Last time we spoke about the invasion of Morotai. After capturing the Marianas and Sansapor, the Allies planned to invade the Palaus and Halmahera. The Japanese stationed the 14th Division at Palau and the 32nd Division at Halmahera. General Ishii, with 11,000 troops, defended Halmahera's nine airfields, while Major Kawashima led 500 Formosans on Morotai. Meanwhile Colonel Nakagawa commanded the forces at Peleliu with extensive defenses, emphasizing attrition tactics. The Allies planned Operation Stalemate for Peleliu and Angaur, with General Geiger's corps set to land on September 15. Aerial reconnaissance and submarine missions informed their strategy. At Morotai, Operation Tradewind was executed by General Krueger’s 31st Division. Supported by air and naval bombardment, Allied troops swiftly secured key areas, encountering minimal Japanese resistance. These operations were part of broader Allied strategies involving coordinated air support and subsequent invasions in the region.

In last weeks episode we talked about the plans and preparations for the invasion of Palau. General Rupertus’ 1st Marine Division was assigned to assault Peleliu while General Mueller’s 81st Division would conduct a dual-pronged landing on Angaur. Meanwhile, Admiral Hoover’s land-based aircraft, General Kenney’s Allied Air Forces, and Admiral Mitscher’s carrier-based aircraft carried out an extensive neutralization program against Japanese airfields within range of Palau. When fighter planes of three fast carrier groups started sweeping over the Palaus on September 6, they found that the efforts of the Southwest Pacific's land-based bombers had succeeded in eliminating many ground targets. Nevertheless, fighters and bombers of the three groups started full-scale attacks on all the principal islands in the Palaus the next day. There was no air opposition, nor had there been any on the 6th. On the 8th, because observable targets were scarce, the weight of attack was reduced, and the carriers began preparing to move to Philippine waters. During their three days at the Palaus, the carrier-based planes flew about 1470 sorties, causing extensive damage to ammunition and supply dumps, barracks, warehouses, and a number of miscellaneous buildings. The groups claimed destruction of only four enemy aircraft, while losing eight of their own.

Admiral Fort’s slower-moving tractor groups, responsible for transporting both divisions to the islands, departed Guadalcanal with their respective screening forces on the morning of September 4. Four days later, fast transports and LSDs also set out to rendezvous with them in the early hours of September 15 after an uneventful voyage. In the interim, Admiral Davison’s carrier group launched a final sweep over the Palaus on September 10. The next day, Rear Admiral Jesse Oldendorf’s Western Fire Support Group and Rear Admiral Ralph Ofstie’s escort carriers arrived to begin the naval gunfire bombardment. Over the following three days, approximately 2,200 tons of naval projectiles were successfully fired on Peleliu. While Japanese positions pinpointed by the fire support ships were generally destroyed, many hidden by natural or man-made camouflage remained intact, as did those in areas not accessible to naval gunfire. Minesweepers cleared the 670 mines laid by the Japanese in the Peleliu-Angaur region and at least 240 more in the Kossol Passage. Nearly 175 mines were destroyed in the four days leading up to the landings, with the remaining mines marked at the cost of one minesweeper. Underwater demolition teams also began clearing obstacles from the landing beaches on September 12, providing the Japanese with clues about the Allied landing plans, leading them to hastily lay many land mines in the last few days.

By 05:15 on September 15, Fort’s transports had finally gathered off the Palaus and taken their assigned positions in the transport areas, ready for the landings to begin. Under clear skies, the small craft and amphibian vehicles of the assault waves formed up without difficulty and moved toward the reefs in front of Peleliu’s White and Orange Beaches. At 05:30, Oldendorf’s cruisers and destroyers started the pre-landing bombardment of the beaches, which was scheduled to cease at 07:50 to allow the carriers to conduct a final sweep. Ten minutes later, the first assault wave began advancing, supported by an LCI rocket barrage and aerial strafing attacks. However, the pre-landing bombardment had been inefficient, leaving many Japanese positions intact. Artillery and mortar fire quickly targeted the American amtracs, with several LVTs taking direct hits. Approximately 26 were destroyed during the landings, their burning hulks cluttering the beaches. Despite the smoke from Japanese fire and burning amtracs, the first wave reached the shore at 08:32. Colonel Chesty Puller’s 1st Marines landed on the left, Colonel Harold Harris’ 5th Marines in the center, and Colonel Herman Hanneken’s 7th Marines on the right. For those of you interested, a rather famous marine was with Harris’s 5th marines this day. Serving with K Company, 3rd battalion, 5th Marines was Eugene Sledge, the author of “with the Old Breed” probably the most famous Pacific War book of all time. If you are a fan of the HBO series: the Pacific, it was based loosely off this book amongst others. I think overall with the Old Breed does an outstanding job, particularly for when it was written, to showcase the brutal reality of the war in the Pacific. Eugene Sledge did not sugar coat things or gloss over terrible things he saw his fellow marines do, such as ripping out gold teeth from dead or even alive Japanese as well as taking human trophies like skulls or hands. Here is a passage:

We learned that our battalion would leave Peleliu as soon as a ship was available to transport us back to Pavuvu. By day we rested and swapped souvenirs, but we had to be on the alert at night for possible Japanese movement. To the south we could hear the constant rattle of machine guns and the thud of mortars and artillery as the 81st Infantry Division kept up the pressure around the Umurbrogol Pocket. “Have you gone Asiatic?” I gasped. “You know you can't keep that thing. Some officer'll put you on report sure as hell,” I remonstrated as I stared in horror at the shriveled human hand he had unwrapped. “Aw, Sledgehammer, nobody'll say anything. I've got to dry it in the sun a little more so it won't stink,” he said as he carefully laid it out on the rock in the hot sun. He explained that he thought a dried Japanese hand would be a more interesting souvenir than gold teeth. So when he found a corpse that was drying in the sun and not rotting, he simply took out his kabar and severed the hand from the corpse, and here it was, and what did I think? “I think you're nuts,” I said. “You know the CO will raise hell if he sees that.” “Hell no, Sledgehammer, nobody says anything about the guys collecting gold teeth, do they?” he argued. “Maybe so,” I said, “but it's just the idea of a human hand. Bury it.” He looked grimly at me, which was totally out of character for his amiable good nature. “How many Marines you reckon that hand pulled the trigger on?” he asked in an icy voice. I stared at the blackened, shriveled hand and wondered about what he said. I thought how I valued my own hands and what a miracle to do good or evil the human hand is. Although I didn't collect gold teeth, I had gotten used to the idea, but somehow a hand seemed to be going too far. The war had gotten to my friend; he had lost (briefly, I hoped) all his sensitivity. He was a twentiethcentury savage now, mild mannered though he still was. I shuddered to think that I might do the same thing if the war went on and on

Its a gripping read, highly recommend it, especially for quote en quote normie friends you might want to get into the Pacific War. Back to the story.Rupertus’ objectives for the first day were to push inland 300 yards to objective line O-1, then attack and capture O-2. Landing simultaneously with the fourth wave were the division's tanks (M-4 Shermans). Because of their excellent waterproofing for the operation, they successfully negotiated the reef, where the worst of the underwater obstacles had been removed by UDTs, and continued toward land in six parallel columns led by their respective LVT guides. The enemy fire, however, proved so intense that over half of 30 tanks organic to the division suffered from one to four hits during the 10 minutes necessary to cross the reef. In the 1st Marines' zone, for example, only one of the assigned tanks escaped being hit during the trip ashore. only three, however, were completely knocked out of action. "Thus within a half hour after the initial landing the infantry had full tank support--a record unsurpassed in any previous Marine landing in the Central Pacific, except for the Marshalls."

To make matters worse, no sooner had the lead elements of 3/1 landed and advanced less than 100 yards inland, than they found themselves confronted by a most formidable natural obstacle, a rugged coral ridge, some 30ft high. This had not shown up on any maps. Worse, the face of this ridge (christened "The Point" by the Marines) was honeycombed with caves and firing positions which the Japanese had blasted into the coral and had turned into excellent defensive positions which resisted all initial assaults. Even after tanks arrived to support the assault troops attempting to storm the northern portion of the ridge, they stumbled into a wide, deep anti-tank ditch, dominated by the ridge itself. Here they came under severe and accurate enfilading fire and were pinned down for hours.

The loss of much communication equipment further left Puller and Rupertus unaware of the situation on the left flank. A major effort was then launched to assault The Point from the rear. It became apparent to the Marines that The Point was unassailable from the front and so eventually units fought inland and assaulted The Point from the rear. These units, commanded by Capt George P. Hunt, fought their way along The Point for nearly two hours, during which time they succeeded in neutralizing all of the enemy infantry protecting the major defensive blockhouses and pill boxes. The principal defense installation was a reinforced concrete casement built into the coral, mounting a 25mm automatic cannon, which had been raking the assault beaches all morning. This blockhouse was taken from above by Lieutenant William L. Willis, who dropped a smoke grenade outside the blockhouse's embrasure, to cover the approach of his men, and Corporal Anderson who launched a rifle grenade through the firing aperture. This disabled the gun and ignited the ammunition inside the blockhouse. After a huge explosion, the fleeing Japanese defenders were mown down by waiting Marine riflemen.

Hunt's surviving 32 men remained isolated on The Point for the next 30 hours, constantly under attack from Japanese infiltrators. Meanwhile, Puller's 2nd Battalion pushed inland about 350 yards against moderate resistance. Despite this success, the 1st Marines' front was divided by two huge gaps. Puller's 1st Battalion was then committed to support the Marines on the left, successfully gaining a foothold on the southern area of The Point, but still unable to close the critical gaps. In the center, Harris' 1st Battalion advanced through coconut groves that provided ample cover, successfully reaching O-1 to link up with Puller's 2nd Battalion in front of the airfield by 09:30. On the right, however, Harris' 3rd Battalion and Hanneken's 3rd Battalion experienced a confused landing and made no progress, with only Harris' Company I reaching O-1 an hour after landing. At 10:30, the two battalions began pushing inland. Harris' Company K rapidly advanced deep into Peleliu's interior under the cover of fairly dense scrub, while the 7th Marines used a large anti-tank ditch to move forward in relative safety.

Again I thought it give more flavor if I took a passage from this moment when K Company advanced from Sledge:

We started to move inland. We had gone only a few yards when an enemy machine gun opened up from a scrub thicket to our right. Japanese 81mm and 90mm mortars then opened up on us. Everyone hit the deck; I dove into a shallow crater. The company was completely pinned down. All movement ceased. The shells fell faster, until I couldn't make out individual explosions, just continuous, crashing rumbles with an occasional ripping sound of shrapnel tearing low through the air overhead amid the roar. The air was murky with smoke and dust. Every muscle in my body was as tight as a piano wire. I shuddered and shook as though I were having a mild convulsion. Sweat flowed profusely. I prayed, clenched my teeth, squeezed my carbine stock, and cursed the Japanese. Our lieutenant, a Cape Gloucester veteran who was nearby, seemed to be in about the same shape. From the meager protection of my shallow crater I pitied him, or anyone, out on that flat coral

Hanneken soon faced strong opposition, leading him to pause his troops and request tank support in the afternoon. The requested tank support became somewhat confused by an unexpected coincidence: the flank battalions of the two assaulting regiments in the center and right were both the 3rd (3/5 and 3/7) with both containing Companies I, K, and L. The unfortunate tank commanders looking for 3/7 who had wandered into 3/5 area due to obstacles - in particular the large anti-tank ditch on Orange 3 - enquired of a body of troops they encountered "is this Company I, 3rd Battalion?" Hearing the right answer in the wrong place, they proceeded to operate with these troops, who were in fact Company I of 3/5 and not Company I of 3/7. Happily, this was one of those confusions of battle that helped more than it hindered. The confusion resulted in a gap between the two regiments as 3/7 paused to take stock of the situation, whereas 3/5 was actually pushing ahead. In an effort to re-establish contact with 3/5, Company L of the 7th Marines worked patrols further and further to the left until its foremost patrol emerged on the southern edge of the airfield. This was completely out of its regimental zone of action and several hundred yards to the rear of the units it was looking for.

By this time, Harris’ 2nd Battalion and Hanneken’s 1st Battalion had landed, with Harris’ battalion pushing vigorously northeast, while Hanneken’s battalion dealt with fierce Japanese resistance and a dense swamp to the south as they advanced toward O-1. Concerned about the slow progress on the right and the heavy casualties suffered by Hanneken’s forces, Rupertus decided to land the divisional reconnaissance company. However, the reserve 2nd Battalion, 7th Marines could not be disembarked until the next day.

One major Japanese counterattack occurred at around 16:50hrs on D-Day, consisting of a tank-infantry sortie in force across the northern portion of the airfield. This attack had been expected by the Marines, especially those of the 5th Marines facing open ground in front of the airfield, and accordingly the regimental commanders had brought up artillery and heavy machine guns as well as tanks to support that area. Increase in Japanese artillery and mortar fire in that area was the first indication that something was brewing. Soon after Japanese infantry was observed advancing across the airfield, not as a fanatical, drunken banzai charge but as a coolly disciplined advance of veteran infantrymen. A Navy air observer spotted Japanese tanks forming east of the ridges above the airfield with more infantry riding on them. These tanks moved forward, passing through the Japanese infantry advancing across the airfield and some 400 yards in front of the Marine lines. For a moment, but only for a moment, the Japanese counter-attack looked like a serious coordinated movement. Then the formation went to pieces. Inexplicably, the Japanese tank drivers opened their throttles wide and raced towards the Marine lines. Charging like the proverbial "Bats outa Hell," with the few infantry atop the tanks clinging on for dear life, they left their accompanying infantry foot support supp far behind. No positive account exists of what happened thereafter. The tanks involved in the charge numbered between 13 and 17 (insufficient pieces were left afterwards to give a definite count) and headed for the Marine lines, cutting diagonally across the front of 2/1, who subjected them to murderous flanking fire from all weapons, small arms, light and heavy machine guns, 37mm antitank guns and artillery. Two of the Japanese tanks veered off into the lines of 2/1, hurtling over a coral embankment and crashing into a swamp, the escaping crews were quickly disposed of by the Marines. Meantime, the remaining tanks came under heavy fire from the marines of 1/5, while the advancing Japanese infantry was subjected to fire and bombing from a passing Navy dive bomber. The tanks and their riding infantry were decimated as they passed right through the Marine lines which simply closed behind them.

At 17:00, a heavy mortar barrage struck Harris’ 3rd Battalion’s command post, causing the Marine companies to lose cohesion, though they eventually formed a defensive line along the airfield's edge. Under this barrage Eugene Sledge had this to say:

Under my first barrage since the fast-moving events of hitting the beach, I learned a new sensation: utter and absolute helplessness. The shelling lifted in about half an hour, although it seemed to me to have crashed on for hours. Time had no meaning to me. (This was particularly true when under a heavy shelling. I never could judge how long it lasted.) Orders then came to move out and I got up, covered by a layer of coral dust. I felt like jelly and couldn't believe any of us had survived that barrage.

By the end of the day, despite 210 men killed and 901 wounded, the progress of the beach expansion was disappointing. Again Eugene Sledge has a passage about getting through the first heat of combat on D-day at Peleliu:

We had to be alert constantly as we moved through the thick sniper-infested scrub. We received orders to halt in an open area as I came upon the first enemy dead I had ever seen, a dead Japanese medical corpsman and two riflemen. The medic apparently had been trying to administer aid when he was killed by one of our shells. His medical chest lay open beside him, and the various bandages and medicines were arranged neatly in compartments. The corpsman was on his back, his abdominal cavity laid bare. I stared in horror, shocked at the glistening viscera bespecked with fine coral dust. This can't have been a human being, I agonized. It looked more like the guts of one of the many rabbits or squirrels I had cleaned on hunting trips as a boy. I felt sick as I stared at the corpses. A sweating, dusty Company K veteran came up, looked first at the dead, and then at me. He slung his M1 rifle over his shoulder and leaned over the bodies. With the thumb and forefinger of one hand, he deftly plucked a pair of hornrimmed glasses from the face of the corpsman. This was done as casually as a guest plucking an hors d'oeuvre from a tray at a cocktail party. “Sledgehammer,” he said reproachfully, “don't stand there with your mouth open when there's all these good souvenirs laying around.” He held the glasses for me to see and added, “Look how thick that glass is. These sonsabitches must be half blind, but it don't seem to mess up their marksmanship any.” He then removed a Nambu pistol, slipped the belt off the corpse, and took the leather holster. He pulled off the steel helmet, reached inside, and took out a neatly folded Japanese flag covered with writing. The veteran pitched the helmet on the coral where it clanked and rattled, rolled the corpse over, and started pawing through the combat pack. The veteran's buddy came up and started stripping the other Japanese corpses. His take was a flag and other items. He then removed the bolts from the Japanese rifles and broke the stocks against the coral to render them useless to infiltrators. The first veteran said, “See you, Sledgehammer. Don't take any wooden nickels.” He and his buddy moved on. I hadn't budged an inch or said a word, just stood glued to the spot almost in a trance. The corpses were sprawled where the veterans had dragged them around to get into their packs and pockets. Would I become this casual and calloused about enemy dead? I wondered. Would the war dehumanize me so that I, too, could “field strip” enemy dead with such nonchalance? The time soon came when it didn't bother me a bit.

During the night, coordinated local counterattacks were repelled with relative ease, thanks to the support from naval gunfire and the artillery of the 11th Marines. However, the enemy’s resistance, which was not the frenzied banzai charges of previous encounters, began to suggest that the prolonged and organized opposition Rupertus had anticipated might indeed persist for a longer time. Meanwhile, with the 3rd Battalion, 15th Regiment cut off to the south, Nakagawa chose to withdraw most of his forces to the ridgelines and high ground north of the airfield, aiming to hold out as long as possible. The 1st Marine Division, enduring a night of harassment from Japanese mortar and artillery fire, faced heavy resistance from these ridgeline defenses on September 16. Despite this, after landing on Peleliu at 09:50, Rupertus made significant progress that day. His only adjustment was to order the reserve 2nd Battalion, 7th Marines to support Puller’s beleaguered 1st Marines to "maintain momentum." On the right flank, the 7th Marines pressed their hold on the southern part of the island despite heavy resistance and thick scrub, capturing all but two small promontories at the southern tip, where isolated defenders established their final positions. In the center, the 5th Marines cleared most of the remaining airfield area and set up defenses at night in a hangar and shop area on the field’s north side, while Puller’s 2nd Battalion secured the northwestern section of the airfield, including several headquarters buildings and barracks.

On the left flank, the 1st Marines struggled to advance against the determined and well-coordinated resistance from Nakagawa’s main defenses, which were concentrated around the Umurbrogol Mountains. Only after intense fighting and with the help of tanks did the Marines manage to capture a 500-yard stretch of the ridge. By nightfall, at the cost of approximately 30 additional men killed and 115 wounded, the division had established a perimeter extending over 3,000 yards from north to south, and about 2,000 yards deep at its farthest point. Over the course of two days, the Americans suffered nearly 1,500 casualties, with more than 1,000 from Puller’s 1st Marines alone. Despite these losses, the crucial objective—the Peleliu airfield area—had been secured. The Japanese defenses had been divided, with two small pockets in the south and the main stronghold in the central ridges. Feeling that operations were progressing well and possibly aiming to keep Peleliu an all-Marine endeavor, Rupertus decided not to request reinforcements from the 81st Division. Consequently, General Mueller’s forces were set to proceed with landings on Angaur the next day. Rear-Admiral William Blandy, commanding the Angaur Attack Group, reported that based on air and naval bombardments, hydrographic surveys, and UDT activities, a successful landing on Angaur appeared achievable. Admiral Fort and General Geiger thus approved the decision. Meanwhile, Major Goto Ushio had stationed his 1,400 men from the reinforced 1st Battalion, 59th Regiment in four defensive sectors with a small reserve in the center.

Expecting the Americans to land on the well-prepared Green Beaches to the southeast, he had fortified that area with his strongest coastal defenses. However, the Americans anticipated this and chose instead to land Colonel Benjamin Venable’s 322nd Regiment on Red Beach to the north and Colonel Robert Dark’s 321st Regiment on Blue Beach to the east. In the early hours of September 17, Blandy positioned his forces off Angaur and at 0530 the Angaur Fire Support Group started its bombardment, employing for the most part slow, methodical area fire rather than shooting at specific targets. The fire was characterized by the 81st Division as being "very satisfactory," and it accounted for about 40 percent of all naval shells thrown at Angaur from 12 through 17 September.

Due to a delay in the arrival of support aircraft, the shore bombardment continued past the scheduled time while General Mueller’s assault troops boarded the landing craft and amphibian vehicles meant to take them ashore. By 08:00, the LVT assault waves began positioning themselves at the line of departure, while the 323rd Regiment executed a feint at Green Beach to distract the Japanese from the actual landing sites. Ten minutes later, the assault waves moved toward the shore, supported by LCI rocket fire, ongoing bombardments, and strafing planes that had also arrived late. Despite encountering only light mortar and small-arms fire, Dark’s forces successfully landed on Blue Beach at 08:31, just one minute behind schedule. Venable’s first wave, however, was delayed and arrived at Red Beach six minutes late. Subsequent waves landed throughout the day amid light resistance but faced challenges such as traffic congestion and limited beach space. By 16:45, all tanks of the 710th Tank Battalion were ashore, and the 316th and 906th Field Artillery Battalions had successfully landed at Red Beach by nightfall. The artillery for Blue Beach was landed the following day. Additionally, Venable’s reserve 2nd Battalion landed by 11:30, and Dark’s reserve 1st Battalion arrived by 13:00.

After landing, Mueller’s green regiments began advancing inland about 300 yards to their first phase line, quickly becoming entangled in dense scrub forests teeming with Japanese machine guns and snipers. On Blue Beach, Dark’s troops proceeded cautiously at first, but by noon they had secured Rocky Point, Cape Ngariois, and established a beachhead approximately 1200 yards long and 350 yards deep. Meanwhile, Venable’s 1st Battalion moved swiftly north and inland through less dense undergrowth to secure its designated beachhead area. The 3rd Battalion bypassed some enemy bunkers set in jagged coral and proceeded south and west, successfully linking up with the 1st Battalion but falling short of reaching Cape Ngatpokul. With two secure beachheads and a 700-yard gap along the first phase line between regiments, Mueller ordered the 322nd Regiment to extend its right flank onto the second phase line about 400 yards inland and to continue pushing south with its left flank towards the sister regiment. By 14:30, the advances resumed, with Venable’s 1st Battalion pushing westward against light resistance into increasingly rough terrain along the coast and into a densely overgrown basin near the north end of Lake Aztec. Meanwhile, the 3rd Battalion engaged in patrol actions against isolated Japanese positions to secure the coastal area between the two landing beaches, though little progress was made. Dark’s forces also struggled, hindered by difficult terrain and mounting Japanese resistance.

Ignoring the gap between regiments, Mueller ordered Venable’s 3rd Battalion to advance to the second phase line. The battalion moved along railroad beds without encountering opposition, reaching the objective by nightfall. Simultaneously, Dark attempted to advance to the second phase line but made little progress before having to dig in. Goto, on the other hand, chose not to launch an immediate mass counterattack, believing that the 81st Division might land at other beaches. Instead, he deployed a company-strength mobile reserve for a counterattack, but this effort was disrupted by air and naval gunfire before it could commence. By late afternoon, realizing that the Americans had firmly established themselves ashore, Goto began moving his units and withdrew the southern defense force to the northwest hills for a final stand. To cover this movement, he ordered a night counterattack by two companies. At 05:50 on September 18, enemy infantry emerged from cover below Rocky Point and attacked Dark’s Company B, pushing the Americans back about 75 yards before being halted by a heavy concentration of fire. Meanwhile, small groups of Japanese forces repeatedly assaulted the defensive line south of Lake Aztec, near the boundary between the 1st and 3rd Battalions. Despite their efforts, they failed to exploit the gap between regiments and withdrew to the northwest hills shortly after dawn.

- 156 - Pacific War Podcast - Battle of Ormoc Bay - November 11 - 18 - , 1944
11 11月· The Pacific War - week by week
Last time we spoke about the advance to Ormoc Valley. As October 1944 unfolded in the Leyte campaign, American forces steadily pushed Japanese troops inland. Despite fierce resistance, they captured key positions, like Dagami, Catmon Hill, and multiple airstrips. While the Japanese reinforced areas like Ormoc, American regiments advanced through challenging conditions, relying on artillery amid minimal air support due to weather and resource constraints. By month's end, American forces had inflicted heavy casualties on the Japanese, securing vital beachheads and pushing closer to full control of Leyte. After suffering losses at Leyte Gulf, the 7th Fleet withdrew, leaving Kenney’s P-38s to defend Tacloban airfields amid Japanese air raids. As kamikaze attacks grew, USS Franklin sustained heavy casualties, while the Americans pressed forward, capturing Carigara on Leyte. Meanwhile, Australian forces began reclaiming New Britain, pushing Japanese forces back through guerilla warfare. Facing tough jungle conditions, Australian and native troops gradually secured strategic positions by December, reinforcing the Allied grip in the Pacific.
This episode is the Battle of Ormoc Bay
Welcome to the Pacific War Podcast Week by Week, I am your dutiful host Craig Watson. But, before we start I want to also remind you this podcast is only made possible through the efforts of Kings and Generals over at Youtube. Perhaps you want to learn more about world war two?

As we have seen over the past few weeks, the Battle of Leyte Gulf saw Generals MacArthur's forces land and successfully defeat the 16th Division of Leyte Island as well as seized Carigara and Pinamopoan over the northern coast. The 24th Division also engaged the enemy’s reinforcements, centred around the elite 1st Division during the battle for the northern entrance into the Ormoc Valley. Meanwhile Admiral Okawachi and General Yamashita aimed to bring more reinforcements to Leyte which would lead to another air-naval battle.
The previous week, Colonel Verbeck’s 21st Regiment was engaged in a mission to capture Breakneck Ridge, fiercely defended by Colonel Miyauchi’s 57th Regiment. Simultaneously, General Kataoka mobilized his remaining two regiments to initiate a broad, four-pronged assault on the Pinamopoan perimeter. However, the rugged terrain slowed their movement toward assembly areas. On the morning of November 8 a typhoon, moving in from the west, swept over the entire island of Leyte. Jan Valtin, a member of the 24th Division, graphically describes it: "From the angry immensity of the heavens floods raced in almost horizontal sheets. Palms bent low under the storm, their fronds flattened like streamers of wet silk. Trees crashed to earth. In the expanse of… [cogon] grass the howling of the wind was like a thousand-fold plaint of the unburied dead. The trickle of supplies was at a standstill. On Carigara Bay the obscured headlands moaned under the onslaught of the… seas. Planes were grounded and ships became haunted things looking for refuge. Massed artillery… barrages to the summit of Breakneck Ridge sounded dim and hollow in the tempest. Trails were obliterated by the rain. The sky was black." In the midst of the storm, the 21st’s infantry attacked.
As the typhoon swept across the island, Verbeck’s forces launched a three-pronged assault on Breakneck Ridge and Hill 1525, facing staunch resistance from Miyauchi’s defenders but making considerable progress toward Hill 1525. Notably, plans for General Suzuki’s offensive were found on a deceased Japanese officer, enabling General Krueger to redeploy his forces effectively. On 10 November General Mudge sent elements of the 1st Cavalry Division to patrol the area of the mountains of central Leyte extensively. From 5 November through 2 December, elements of the 1st Cavalry Division extensively patrolled the central mountain area and had many encounters with small forces of the enemy. At all times the supply situation was precarious. The 12th Cavalry established high in the foothills, at the entrance to the passes through the mountains, a supply base that was also a native camp, a hospital, and a rest camp. About 300 Filipino carriers were kept here under the protection of the guerrillas. The carriers had been hired for six days at a time and were not allowed to leave without a pass from their Filipino leader. This precaution was necessary, since the ration-carrying assignment was extremely arduous. The cavalrymen would frequently skirmish with the 41st Regiment and the 169th and 171st Independent Battalions during this period. Brigadier-General Julian Cunningham’s 112th Cavalry Regiment, expected by November 14, was tasked with relieving General Mudge’s 1st Cavalry Division in the Carigara-Barugo area to enable a southwest advance from the central mountains and ease pressure on General Irving’s 24th Division.
General Bradley’s 96th Division was directed to capture the high ground between Jaro and Dagami, with the 382nd Regiment remaining at Dagami to inflict significant losses on the 16th Division while securing Bloody Ridge. By November 4, the 382nd Regiment had made some progress into Bloody Ridge. The night of 4-5 November was not quiet. The Japanese delivered harassing fire on the 1st Battalion, and at 2205 elements of the 16th Division launched a heavy assault against the perimeter of the 2d Battalion. An artillery concentration immediately stopped the attack, and the Japanese fled, leaving 254 dead and wounded behind them. The following morning, after the artillery had fired a preparation in front of the 1st and 2d Battalions, the two battalions renewed the attack at 0900 and two companies from the 3d Battalion protected the regimental left (south) flank. The battalions advanced about 1,000 yards before they encountered any strong resistance. The defenses of the 16th Division consisted of a great many concrete emplacements, concealed spider holes, and connecting trenches. By nightfall, at 1700, the two battalions, assisted by the tanks from Company A, 763d Tank Battalion, successfully reduced the enemy to their front and captured the ridge. Each battalion formed its own perimeter and made plans to renew the attack on 6 November. At 0830 the 1st Battalion, with light tanks in support, moved out in the attack westward against a strong enemy force that was well entrenched in foxholes and pillboxes. Each of these defensive positions had to be reduced before the advance could continue. At 1300 the 2d Battalion moved to the high ground on the right flank of the 1st. The 1st Battalion encountered a strong concrete enemy pillbox which was believed to be a command post, since there were no firing apertures. As grenades had no effect it became necessary finally to neutralize the pillbox by pouring gasoline down the ventilation pipes and setting it afire. Two officers and nineteen enlisted men of the enemy were killed in the pillbox. The Japanese continued to fight tenaciously. There was no withdrawal, but by the end of the day only isolated pockets of enemy resistance remained. The Japanese 16th Division was taking a bad beating. Its supply of provisions had run out. All the battalion commanders, most of the company commanders, and half the artillery battalion and battery commanders had been killed. On the night of 6 November the 16th Division contracted its battle lines and on the following day took up a new position in the Dagami area. The new position ranged from a hill about four and a half miles northwest of Dagami to a point about three and three-fourths miles northwest of Burauen. On 7 November all three battalions of the 382d Infantry engaged the enemy and maintained constant pressure against his positions. The 1st and 3d Battalions advanced west, while the 2d Battalion drove north and west. The 3d Battalion encountered -the more determined resistance. Advancing, preceded by tanks, it met heavy enemy machine gun and rifle fire. A large enemy force assaulted the troops at close quarters and tried to destroy the tanks, but when the 382d Infantry introduced flamethrowers and supporting machine guns, the attackers fell back in disorder. The regiment overran the Japanese defensive positions and killed an estimated 474 of the enemy. Company E of the 2d Battalion had remained in the Patok area, engaged in patrolling and wiping out isolated pockets of enemy resistance. On 8 November strong patrols from the 1st and 2d Battalions probed west into the hills. They encountered the left flank of the enemy supporting position at a point about 2,600 yards west of Patok. A very heavy rainfall on the night of 8-9 November made an assault against the position impossible on 9 November. After all-night artillery fire, the 1st and 3d Battalions moved out at 0900 on 10 November. They met no resistance, but progress was slow because of the swamps. By 1225 the two battalions, supported by a platoon of light tanks, occupied the ridge formerly held by elements of the 16th Division. The 1st Battalion had advanced 2,500 yards. The 382d Infantry had destroyed all organized enemy resistance in its sector and removed the threat to Dagami.
Meanwhile, General Arnold’s 7th Division stationed at the Burauen-Abuyog area began sending patrols from Baybay toward Ormoc to prepare for a larger advance, while the 2nd Battalion, 32nd Regiment moved to Baybay, successfully ambushing the Japanese unit advancing to Abuyog. Concurrently, Okawachi sent his fourth convoy from Manila, consisting of three transports, four frigates, and six destroyers under Admiral Kimura. This convoy carried the bulk of General Yamagata’s 26th Division and approximately 3,500 tons of supplies, followed by another echelon of three transports with the remainder of the 1st Division.
The echelon reached Ormoc the next day, unloaded successfully, and departed without issue. However, the main convoy encountered air attacks as it approached Ormoc Bay, beginning its debarkation by nightfall. On 10 November the 38th Bomb Group, based on Morotai, sent 32 B-25 Mitchells escorted by 37 P-47 Thunderbolts to attack TA-4 near Ponson Island. Reaching the convoy just before noon, the B-25s attacked at minimum altitude in pairs, sinking the two largest transports, Takatsu Maru and Kashii Maru, disabling a third, and sinking two of the patrol craft escorts at a cost of seven bombers, for which the group was awarded the Distinguished Unit Citation.
Although Yamagata’s troops were finally ashore by November 10, most of the supplies couldn't be unloaded due to ongoing enemy air attacks. Shortly after leaving Ormoc, American planes intercepted the convoy, destroying two transports and one frigate, while further damaging another frigate and a destroyer. Meanwhile, Okawachi dispatched a third convoy, consisting of five transports, a submarine chaser, and five destroyers under Rear Admiral Hayakawa Mikio, transporting special troops and heavy equipment of the 26th Division. When one transport ran aground on Luzon’s Bondoc Peninsula, Kimura sent two frigates and three destroyers to transfer its cargo to Ormoc. As a result, Hayakawa’s convoy arrived at Ormoc Bay on November 11 and began unloading. However, ULTRA intercepts had detected the enemy convoy departing Manila, prompting Admiral Halsey to redeploy Task Force 38 under Admiral McCain. While under repair at Manila on 29 October, Nachi and Kumano were attacked by aircraft from USN Task Force 38. Nachi was hit by a single bomb to her aircraft deck, and this, as well as strafing attacks, killed 53 crewmen and further delayed repairs. On 5 November, again in Manila Bay, Nachi was attacked by three waves of U.S. planes from the aircraft carriers USS Lexington and Ticonderoga. She escaped the first wave undamaged, but was hit by five bombs and two or three torpedoes in the second wave while attempting to get underway. During the third wave, Nachi was hit by five torpedoes in her port side, which severed her bow and stern, and by an additional 20 bombs and 16 rockets. Nachi's flag commander, Vice Admiral Kiyohide Shima, was ashore for a conference at the time of the attack, but arrived at dockside in time to see his flagship blown apart. The central portion of the vessel sank in 102 feet (31 m) of water about 12 nautical miles (22 km) northeast of Corregidor. McCain launched an attack on Kimura’s convoy. Just as unloading began, 347 planes struck, sinking all four transports and four destroyers, including the flagship Shimakaze, on which Hayakawa lost his life. This costly reinforcement operation thus ended in partial failure, with most equipment lost and over 1,500 casualties. Nevertheless, elements of the 1st Division moved immediately toward the Limon area, while Yamagata’s units, though short on weaponry, were ordered to assemble at Dolores to prepare for joining the Imahori Detachment at Daro.
At the same time, noticing the rapid advance of the enemy into the Carigara area, Yamashita concluded that Suzuki’s proposed offensive toward Tacloban was destined for failure. He ordered the main force of the 35th Army to join the 16th Division in the advantageous mountainous positions of the Burauen-Dagami area to regain control of the recently captured airstrips, thereby limiting operations in the Carigara area to a holding action. Concurrently, as this adjustment to the tactical plan was made, Yamashita communicated his growing belief that the overall situation offered little hope for victory on Leyte and unsuccessfully tried to persuade General Terauchi to shift the decisive battle to Luzon. As a result of Terauchi’s decision, the 68th Brigade was still to be sent to Leyte; the 23rd Division was scheduled to go to Manila in mid-November before returning to Leyte; and the 10th and 19th Divisions were planned for movement to the island by the end of the year. With the plans finalized for continuing the decisive battle on Leyte, Terauchi’s headquarters departed Manila for Saigon on November 17. Back on Leyte, on November 9, the weary, mud-stained troops of the 21st Regiment launched another attack, with the 3rd Battalion assaulting the center of Breakneck Ridge and the 2nd Battalion targeting OP Hill, though they made only minor gains. Additionally, Verbeck’s 1st Battalion attacked Limon but was repelled by heavy enemy fire, and fresh Japanese troops subsequently counterattacked the Hill 1525 position, forcing the Americans to retreat. Finally, Colonel Chapman’s 2nd Battalion reached the western slopes of Hill 1525 in the afternoon, but it was too late for them to take part in the battle.
On November 10, Verbeck continued his assault, successfully capturing OP Hill and making significant headway in the area. At the same time, Chapman’s 2nd Battalion began advancing westward to establish a roadblock on Highway 2, approximately 2000 yards south of Limon. Meanwhile, Lieutenant Colonel Thomas Clifford’s 1st Battalion of the 34th Regiment landed on the western shore of Carigara Bay and initiated a wide envelopment around the western flank of the 57th Regiment to secure the high ground known as Kilay Ridge. Additionally, Mudge’s cavalrymen pressed forward toward Mount Minoro. On this day, Yamashita’s adjustments to the tactical plan finally reached Suzuki’s headquarters. As a result, Suzuki abandoned his initial strategy and directed Yamagata to move his troops quickly to Albuera to prepare for an offensive eastward, dubbed Operation Wa. To replace the 26th Division in upcoming operations on the Jaro front, Suzuki decided to deploy the 30th Division, which had not yet departed Mindanao, instructing them to land at Ipil and prepare to support the Imahori Detachment, already skirmishing with Bradley’s patrols.
On November 11, following a heavy artillery barrage, Verbeck resumed his assault, although the 2nd Battalion quickly found itself pinned down, while the 1st Battalion successfully secured a ridge 300 yards southwest of OP Hill. The next morning, the 1st and 3rd Battalions advanced against the crest of Breakneck Ridge, successfully capturing the objective before being halted by Japanese artillery fire. At the same time, Chapman’s 2nd Battalion reached Highway 2, and Clifford’s 1st Battalion, supported by elements of the guerrilla 96th Regiment, arrived in the Cabiranan area. By November 13, Verbeck’s 1st and 2nd Battalions advanced 600 and 400 yards, respectively, without encountering opposition.
Breakneck Ridge was secured, although the Japanese maintained control over several nearby spurs, particularly Corkscrew Ridge. Nonetheless, the 21st Regiment reported approximately 1,779 Japanese soldiers killed, suffering 630 casualties in the process. Additionally, Clifford’s 1st Battalion successfully reached Kilay Ridge undetected and quickly established defensive positions. At 0855 on 13 November a column of Filipino men, women, and children entered the perimeter and brought approximately thirty-five boxes of rations from Consuegra. The battalion left the area at 0930 and reached the ridge without opposition. Trenches and prepared gun positions without a man in them honeycombed the ridge from one end to the other. It was evident that elements of the 1st Division had intended to occupy the area in the latter stages of the battle for Limon. On 14 November Colonel Clifford ordered his battalion to entrench itself along the ridge in positions that would afford the best tactical advantage. The battalion established strong points and observation posts on the knolls, placed blocks on the trails leading through the area, and sent out reconnaissance patrols to locate enemy positions. Colonel Clifford made arrangements to utilize the Filipinos as carriers. These men were to use a trail on the north end of the ridge and bring supplies to the battalion from a supply dump at Consuegra. The first human pack train arrived in the area at 1010 with twenty-eight cases of rations and a supply of batteries for the radios. At 1125 enemy artillery shelled the southern end of the ridge and twenty minutes later shifted its fire to the Limon area. The battalion did not succeed in establishing physical contact with the 2d Battalion, 19th Infantry, which was operating east of the road, but it was able to make radio contact. Throughout the day, patrols of the battalion were active in searching out enemy positions.
Meanwhile the 112th Cavalry was landed at Carigara and attached to the 1st Cavalry Division to strengthen the assault on the central Leyte mountains. Meanwhile, the reserve 32nd Division, led by Major-General William Gill, was also dispatched to the island to relieve the fatigued 24th Division. This newly arrived division was assigned the mission of capturing Limon and advancing down the Ormoc Valley toward Ormoc. On the Japanese side, after receiving the rest of his division, Kataoka chose to move the 1st Regiment to the left flank to assist the 57th, which had also been bolstered by two fresh battalions. This combined force aimed to launch an attack along the main road toward Pinamopoan while the 49th Regiment and the 171st Independent Battalion sought to envelop the enemy's left flank toward Colasian. By mid-November, the headquarters of the 102nd Division and most of the 364th Independent Battalion had also arrived in Ormoc, with Lieutenant-General Fukei Shinpei taking command of the 41st Regiment and his other battalions on the island as they advanced toward Mount Pina. Furthermore, despite significant losses to enemy aircraft, five air regiments had reinforced the 4th Air Army, enabling General Tominaga to make the 4th Air Division fully operational, a unit that had previously focused solely on base activities and anti-submarine patrols.
The replenishment of naval air strength was progressing well, with replacement aircraft for the 1st Combined Base Air Force outnumbering losses by 26% in November. On November 15, the Combined Fleet opted to cease training carrier air groups and instead focus on expanding the base air forces. The 3rd Air Fleet, stationed in the homeland, was tasked with training replacement units for deployment to the Philippines. Due to the successful reinforcement of Japanese air forces in the Philippines and General Kenney’s ongoing inability to provide close air support, Halsey once again directed Task Force 38 to attack enemy airbases on Luzon. On November 13 and 14, McCain’s carriers conducted several strikes against Japanese airfields in Luzon, resulting in a significant decrease in enemy air operations over Leyte.
On 13 November 1944, on the threat of American carrier strikes on Luzon, Kiso was ordered to return to Brunei that evening carrying Vice Admiral Kiyohide Shima. Before she could leave for Brunei, she was attacked on 13 November while underway in Manila Bay by more than 350 carrier planes of Task Force 38's carrier task groups 38.1's Hornet, Monterey and Cowpens, TG 38.3's Essex, Ticonderoga and Langley and TG 38.4's Enterprise and San Jacinto. Three bombs hit Kiso to starboard - one in the bow, one near her boiler rooms and one near her aft gun mounts. Kiso sank in shallow water 13 kilometres (7.0 nmi; 8.1 mi) west of Cavite. Captain Ryonosuke Imamura and 103 of her crew survived, but 175 crewmen went down with the ship. Akebono, while alongside destroyer Akishimo at Cavite pier near Manila, was attacked in a USAAF air raid. A direct bomb hit set both ships ablaze, and the following day a large explosion on Akishimo blew a hole in Akebono, which sank upright in shallow water, with 48 crewmen killed and 43 wounded. After returning to Manila, Hatsuharu was caught in an air raid in Manila Bay. A series of near misses buckled plates and set fires, causing the ship to sink in shallow water. The attack killed 12 crewmen and injured 60 more, but 218 survived. Several other vessels were also sunk.
Meanwhile, on November 14, the Hi-81 convoy, comprising the escort carriers Shinyo and Akitsu Maru, destroyer Kashi, seaplane tender Kiyokawa Maru, submarine chaser No. 156, seven escort ships, five oilers, and three transports, left Imari Bay under Rear-Admiral Sato Tsutomu. The convoy carried most of Lieutenant-General Nishiyama Fukutaro’s 23rd Division and headed into the Yellow Sea, wary of enemy submarines. After stopping for the night in Ukishima Channel near the Gotō Islands, Sato’s convoy resumed its journey on November 15 but was soon ambushed by two submarine wolfpacks. Commander Charles Loughlin’s submarines were the first to strike, successfully hitting the Akitsu Maru with two torpedoes, which later sank, resulting in the loss of 2,046 lives, including most of the 64th Regiment.
After the attack, Sato withdrew to Strange Island, located off the coast of Korea, to take refuge for the day. On the morning of November 17, the convoy resumed its journey but was soon detected by a B-29 Superfortress as it made its way toward the Shushan Islands. By late afternoon, Commander Gordon Underwood's submarines launched an assault on the Japanese ships, successfully striking the transport vessel Mayasan Maru, which sank quickly, resulting in the loss of 3,437 men, including most of the 72nd Regiment. Almost twelve hours later 200 kilometers off Saishu Island, Spadefish surfaced and attacked the Shinyo with six torpedoes. Four struck the carrier on the starboard at 11:03 pm, and it caught fire. At least 1,130 Japanese sailors went down with their ship; only about seventy survived, including Ishii. Kashi immediately dropped several depth charges where the Spadefish was thought to be. An oil slick and other debris eventually made the Japanese believe they had sunk Spadefish so the Kashi broke off the engagement, but Spadefish had escaped apparently without serious damage. Only minor cracks were reported to have appeared on the submarine after the alleged "sinking" by Kashi. Underwood's final strike was against the submarine chaser No. 156, which sustained three torpedo hits and sank rapidly. Following some rescue efforts, Sato continued his advance on November 21, eventually arriving in Kaohsiung five days later. Half of the convoy then proceeded to San Fernando, where the remaining members of the 23rd Division disembarked on December 2.
Yet thats it for today for the Philippines as we now need to shift over to Morotai.With Japanese reinforcements pushed back into the interior of the secured island, General Persons directed the 31st Division to capture several islands off New Guinea that served as observation points for Japanese outposts monitoring Allied movements. On November 15, the 2nd Battalion of the 167th Regiment landed on Pegun Island, followed by a successful attack on Bras Island the next day. By November 18, with the Mapia Islands secured, Company F of the 124th Regiment was sent to occupy the unguarded Asia Islands on November 19.
In the Aitape region, Major-General Jack Stevens' 6th Australian Division was assigned to relieve American forces, similar to the Australian efforts on New Britain and Bougainville, in order to free up troops for the Philippines Campaign. By late October, a base had been successfully set up, allowing the 19th Brigade to arrive by mid-November, with the 17th Brigade scheduled for early December, and the 16th by year-end. Under General Blamey's orders, the new Australian garrisons were to adopt a more active approach than the American units had, so Stevens planned not only to secure the airfield and radar installations in the Aitape-Tadji area, but also to carry out extensive patrols in support of intelligence and guerrilla operations aimed at weakening the enemy in Wewak.
One of General Stevens’ tasks was to give maximum help to AIB. and Angau units in the area in their tasks of gaining Intelligence, establishing patrol bases and protecting the native population. These AIB. and Angau units had been active in the Sepik-Aitape triangle since the time of the landing of American forces at Aitape in April 1944, and the 6th Division came into an area where, from the outset, practically all the deep patrolling had been done by groups of Australians. In the Aitape area, prior to the arrival of the Division (said the report of the 6th Division), Angau long-range patrols operated without troop support and, for their own protection, inaugurated a type of guerilla warfare. Selected village natives called "sentries" were taught to use grenades and Japanese rifles. The sentries, besides furnishing Intelligence, accounted for large numbers of enemy. This system was continued. As each area was freed the sentries were rewarded and returned to their villages.
By early November, the 2/10th Commando Squadron had established a patrol base at Babiang, conducting numerous patrols throughout the month. Intelligence gathered suggested the Japanese forces were weakened, poorly nourished, and mainly focused on sourcing food. In response, Stevens planned two significant December operations: to sever the enemy’s communication line along the Malin-Walum-Womisis-Amam axis and to neutralize enemy positions east of the Danmap River. By November 25, the seasoned 2/7th Commando Squadron had arrived at Babiang, and by month-end, the 19th Brigade took over the area. The commandos then advanced southward, setting up a base at Tong on December 4 and establishing an outpost at Kumbum three days later.
Now to finish this week's episode let's explore the B-29 Superfortress operations during this time. After the Formosa Air Battle and the Omura raid on October 25, General LeMay’s 20th Bomber Command conducted four missions in November. Three of these supported Southeast Asia operations as part of “PAC-AID,” while the fourth targeted the Omura Aircraft Factory, a key focus for the command. On November 3, 44 B-29s from India effectively bombed the Malegon Railway Yards at Rangoon. Two days later, 53 bombers hit Singapore’s King George VI Graving Dock, the largest of several dry docks at Singapore and one of the world’s best. The first of 53 Superforts attacking was over target at 0644, and the bombardier, Lt. Frank McKinney, put a I,ooo-pound bomb into the target within 50 feet of the aiming point, the caisson gate; Lt. Bolish McIntyre, 2 planes back, laid another alongside. This was the sort of pickle-barrel bombing the Air Corps had talked about before the war. Strike photos showed a rush of water into the dock, presumptive evidence that the gate had been strained, and subsequent reconnaissance photos indicated that the dock was out of use (A-2’s estimate of three months of unserviceability was to prove quite accurate). There were other hits on the dock, on a 465-foot freighter in it, and on adjacent shops. For “baksheesh,” as the boys had learned to say in India, seven B-29’s bombed the secondary target, Pangkalanbrandan refinery in Sumatra, and reported direct hits on the cracking plant. The Japanese, evidently relying on the inaccessibility of Singapore, put up a feeble defense, but the long trip took a toll of two planes and twelve crewmen, including Col. Ted L. Faulkner, commander of the 468th Group. On November 11, 96 B-29s launched from China to strike Omura under difficult weather; only 29 reached the aircraft factory unsuccessfully, while 24 more bombed Nanking with limited results. The month’s final mission on November 27 saw 55 B-29s severely damage the Bang Soe marshaling yards in Bangkok.
Meanwhile, in the Marianas, General Hansell’s 21st Bomber Command prepared for strikes on the Japanese Home Islands. In order to properly plan missions to Japan, up-to-date reconnaissance photos of the proposed targets were needed. Other than information which was used during the Doolittle Raid in 1942, there was scant information about the locations of Japanese industry, especially the aircraft industry. On November 1, two days after arriving on Saipan, a 3rd Photographic Reconnaissance Squadron F-13A Superfortress (photo reconnaissance-configured B-29) took off bound for Tokyo. The aircraft flew over Tokyo at 32000 feet for 35 minutes taking picture after picture. A few fighters made it up to the camera plane's altitude but did not attack. These photos, along with other intelligence, gave the 21st Bomber Command the locations of the Japanese aircraft manufacturing plants and enabled mission planners to plan missions for the combat crews to attack. In honor of his mission, the aircraft was named "Tokyo Rose". In response, about ten G4Ms launched from Iwo Jima attacked Isley Field on Saipan the next day, scoring five bomb hits but losing three bombers. Hansell responded with a practice strike on Iwo Jima on November 5, though results were again limited.
On November 7, the Japanese launched a follow-up attack, but it again resulted in minimal damage and cost them three bombers. A retaliatory strike by 17 B-29s the next day also fell short: one squadron had to jettison its bombs into the ocean, while another dropped its load through a gap in the undercast. Between Japanese attacks, American aircrew inexperience, delays in constructing airfields in the Marianas, and the slow movement of B-29s to Saipan, the 21st Bomber Command was behind schedule in its planned offensive against Japan. By November 15, only half of the 73rd Bombardment Wing’s authorized 180 B-29s had arrived, but by November 22, around 118 bombers were finally in place. At this point, General Arnold ordered Hansell to begin Operation San Antonio I, marking the first strike against Tokyo. The chosen target was Nakajima’s Musashi Aircraft Engine Plant, which supplied 27% of Japan's combat aircraft engines. On November 24, 111 B-29s took off for Japan, collectively carrying 277.5 tons of bombs. However, 17 bombers aborted mid-flight, and six others couldn’t bomb due to mechanical issues. For the first time, the B-29s encountered the Jet stream, which was a high-speed wind coming out of the west at speeds as high as 200 mph at precisely the altitudes at which the bombers were operating. This caused the bomber formations to be disrupted and made accurate bombing impossible. As a result, only 24 B-29s bombed the Musashi plant, while 64 hit nearby dock and urban areas instead. The Japanese fighter response was less intense than expected, with the Americans claiming to have downed seven fighters, likely destroyed 18 more, and damaged nine, losing just one bomber in return. Another B-29 was lost on the return trip after running out of fuel and ditching.
Despite disappointing bombing results in the mission—only 48 bombs struck the factory area, causing damage to just 1% of the building area and 2.4% of the machinery, with 57 killed and 75 injured—the raid exposed the weaknesses in Japan's air defense and showed the six million residents of Tokyo that they were vulnerable to attack. Given the limited impact of the November 24 mission, Hansell decided to launch a second major strike, dubbed San Antonio II, targeting Musashi once more. However, in the early hours of November 27, two G4M bombers from Iwo Jima carried out a low-altitude raid on Isley Field, escaping after destroying one B-29 and damaging eleven others.
Later that day, twelve bomb-equipped Mitsubishi A6M "Zero" fighters from the IJN's 252 Kōkūtai (252 Air Group) accompanied by two Nakajima C6N "Myrt" reconnaissance aircraft for navigation purposes departed Iwo Jima for Saipan. The attackers flew just above sea level to avoid US radar, and one of the A6Ms was forced to divert to Pagan after its propeller struck a wave; this aircraft was shot down by a USAAF Thunderbolt while attempting to land. The remaining eleven A6Ms arrived over Saipan at noon, shortly after XXI Bomber Command's second raid on Tokyo had departed. These aircraft strafed Isley Field destroying three or four B-29s and damaging up to two others. One of the Japanese pilots landed his fighter on Isley Field and fired on airfield personnel with his pistol until he was killed by rifle fire; this incident was witnessed by Brigadier General Haywood S. Hansell, the commander of XXI Bomber Command. None of the ten other A6Ms survived; four were shot down by USAAF fighters and six by anti-aircraft guns. The U.S. gunners also downed a USAAF Thunderbolt in circumstances which an official assessment later described as "inexcusable".
Of the 81 bombers launched, 19 aborted, and those that reached Tokyo found the target covered by clouds, forcing them to drop bombs by radar over Tokyo's docks, urban areas, and the cities of Hamamatsu, Shizuoka, Numazu, and Osaka. Ultimately, for the loss of one Superfortress, the damage caused by this second strike was minimal. However, the strong Japanese response led Hansell to relocate some B-29s from Isley to safer Guam, strengthen Saipan’s defenses and radar, and plan coordinated air-sea operations to neutralize Iwo Jima's staging fields.

The Americans pressed through Leyte’s treacherous terrain and fierce resistance, aiming to secure strategic positions. Typhoons, enemy reinforcements, and brutal battles tested them harshly, but they advanced steadily. Despite heavy losses and airstrikes from both sides, American forces captured Breakneck Ridge and pushed onward, inching closer to victory.

4 11月· The Pacific War - week by week
Last time we continued speaking about the Battle of Leyte Gulf. Admiral Toyoda's Operation Sho-Go aimed to eliminate American naval forces but faced setbacks with the loss of key ships. As Japanese forces advanced, miscommunications led to disorganized attacks. Rear-Admiral Clifton Sprague’s Taffy groups used smoke and air assaults to delay the Japanese, ultimately leading to Kurita's retreat after sustaining heavy damage from American air strikes. On October 25, a series of intense naval engagements unfolded, featuring airstrikes and kamikaze attacks. U.S. forces launched multiple strikes against Japanese carriers, inflicting significant damage but facing challenges from anti-aircraft fire and pilot fatigue. The day ended with the sinking of several Japanese vessels, including Zuikaku and Chitose, resulting in substantial casualties. Admiral Halsey attempted to intercept Kurita’s forces but was too late. Despite heavy losses, including the cruiser Abukuma and numerous aircraft, Kurita's forces managed to reach safety. The battle marked a significant defeat for the Japanese, severely weakening their naval capabilities, though Kamikaze attacks prolonged the war.

Last we we covered the climax of the battle of Leyte Gulf seeing the IJN basically annihilated in the waters surrounding the philippines. As the confrontation drew to a close, General Krueger's offensive was ongoing at Leyte. By October 26, General Sibert's 10th Corps and General Hodge's 24th Corps had successfully established two beachhead areas, gradually expanding their perimeter inland and pushing General Makino's 16th Division further into the island's interior. Following the failure of his earlier repositioning after the loss of Hindang and Burauen, Makino acknowledged that he could not prevent the loss of the eastern coastal plain. He decided to retreat his units to rear positions in the mountains west of Dagami and Burauen. Concurrently, as part of Operation TA, Admiral Mikawa successfully delivered the first reinforcements to Ormoc. Consequently, General Suzuki promptly ordered Colonel Sumitani Takayoshi's 41st Regiment to move towards Carigara and then to Jaro, where the remnants of the 33rd Regiment had fallen back to maintain the division's left flank.
After capturing Hills B and C, the 24th Division resumed its westward assault on October 26. With General Mudge's 1st Cavalry Division protecting General Irving's northern flank, the 34th Regiment advanced along Highway 2, reaching Santa Fe, while the 19th Regiment attempted to attack Pastrana but was halted short of its objective by heavy enemy fire. To the south, the 383rd Regiment patrolled towards San Vicente Hill amidst fierce resistance, as the 382nd Regiment attacked Tabontabon but was forced back to the Guinarona River by determined defenders. In addition, the reserve 3rd Battalion, 381st Regiment, embarked on a long march north along Highway 1 towards Tanauan but encountered enemy fire near Vigia Point.
Further south, the 17th Regiment successfully advanced to a position about 600 yards south of Guinarona, while the 32nd Regiment fought persistently to reach the edge of the Buri airstrip. The following day, after fending off several light counterattacks, the 32nd finally secured the airstrip with minimal resistance. Additionally, the 17th pushed forward to a point approximately 2,200 yards south of Dagami, although they faced increased opposition from the retreating enemy. To the east, following an extensive artillery bombardment, the 382nd captured a majority of Tabontabon in a coordinated attack, with Colonel Dill's 1st and 3rd Battalions then moving northeast toward Kapahuan. Colonel Michael Halloran's 3rd Battalion pressed northward and ultimately took Tanauan without opposition before heading towards Kiling. Meanwhile, in the Catmon Hill area, after General Krueger released the remainder of the 381st Regiment to the control of the 24th Corps, General Bradley decided to deploy his reserve regiment to take control of the Labiranan Head position in preparation for an assault against Catmon hill.
Catmon Hill had been under steady naval and artillery fire since A Day, October 20. The 96th Division artillery had constantly fired on targets of opportunity by day and harassed enemy positions in the area during the night. Starting at 21:00 on October 27, the 105-mm howitzers of the 361st Field Artillery Battalion, the 155-mm howitzers of the 198th Field Artillery Battalion, a battery of 155-mm howitzers from the 363d Field Artillery Battalion, and the 75-mm howitzers from the 780th Amphibian Tank Battalion were to deliver harassing fires on the hill until 10:30 the following day. At that time all of the artillery units were to commence firing successive concentrations beginning at the bottom of the hill and working to the top in 50-yard bounds. After the 381st Regiment, less the 3rd Battalion, attacked at 12:00 on October 28, the artillery was to fire concentrations in front of the troops as they advanced. In making his plans for the capture of Catmon Hill, Colonel Michael E. Halloran, commander of the 381st Regiment, decided to have the 1st Battalion make an enveloping movement from the northeast while the 2nd Battalion pushed west along the main ridge. The 1st Battalion, 383rd Regiment, from its position on Labiranan Head, would support the attack by fire.
Further north, Irving's push westward continued as the 34th Regiment advanced unopposed to the Mudburon River, while the 19th Regiment captured Pastrana following another heavy artillery barrage. On that day, the 171st Independent Battalion arrived after a week-long voyage from Panay, preparing to join the 41st Regiment and its sister battalion towards Carigara and Jaro. On October 28, as the 41st Regiment passed through Carigara and approached Jaro, Mikawa launched his second Operation TA convoy, consisting of three echelons. The first echelon left Manila immediately without cover, transporting the 20th Antitank Battalion. Simultaneously, preparations were underway to send the 12th Independent Regiment and the recently arrived 1st Division to Leyte.
Meanwhile, the 34th Regiment swiftly moved through Alangalang and advanced to the Mainit River, where they were ultimately halted by fierce Japanese resistance. Nevertheless, two companies successfully crossed the river unnoticed during a heavy rainstorm. After launching a surprise assault against the defenders, they captured a bridge over the river. At the same time, the 19th Regiment progressed to Tingib, where it established a patrol base. General Hoffman also directed his 2nd Cavalry Brigade to advance toward Carigara, with the 2nd Squadron, 8th Cavalry making an overland move to San Miguel, while Troop C of the 7th Cavalry conducted an amphibious landing at Barugo, later engaging in skirmishes with Japanese forces at Carigara. To the south, after successfully fending off a vigorous counterattack, Colonel Dill’s 2nd Battalion secured the Tabontabon area, enabling it to move north toward Kiling. In spite of determined opposition, the Japanese supply center of Tabontabon had at last been taken and approximately 350 Japanese killed in the area. During the three days of fighting, the 2d Battalion had thirty-four men killed and eighty wounded.
The remainder of the 382nd fought their way to Digahongan before turning towards Kiling, eventually halting at Kansamada. Meanwhile, while the 383rd conducted reconnaissance toward San Vicente and the 9th Regiment began its retreat to Dagami, the 381st Regiment finally launched its assault on Catmon Hill. However, Halloran’s two battalions were met with heavy gunfire from the surrounding foothills. Lastly, as the 184th Regiment patrolled toward Santa Ana, the 17th Regiment attacked toward Dagami. Despite facing strong opposition and difficult swamp conditions, they managed to push 300 yards beyond the enemy stronghold by nightfall, rolling up the defenders’ eastern flank.
Since the 2d Battalion had borne the brunt of the fighting on 28 October and had suffered numerous casualties, the regimental commander decided to have the battalion drop back into reserve. Although the drive to Dagami was to continue, the north-south line of enemy pillboxes on the left flank of the regiment could not be ignored. At 0800 on 29 October the regimental lines were to be reorganized so that the 3d and 1st Battalions, less Company B, would pass through the 2d Battalion, which would become the regimental reserve. Company B with a platoon of M8's would attack the flank and rear of the enemy in the left line of pillboxes. At 0800, under cover of a heavy artillery concentration from the 49th Field Artillery Battalion, the 1st and 3d Battalions, 17th Infantry, passed through the 2d Battalion without incident. Company B, reinforced by the platoon from the Cannon Company, moved out to destroy the enemy force on the regiment's left flank. The company fought the Japanese from pillbox to pillbox, catching the enemy on his flanks and rear by rifle and machine gun fire, together with time-burst fire from the self-propelled howitzers. This completely demoralized the Japanese, some of whom threw down their arms and tried unsuccessfully to escape. More than 120 enemy dead were counted in the area. The 1st Battalion entered the southern part of Dagami without encountering serious resistance. It then came under artillery fire from the hills west of the town. The 3d Battalion proceeded east of the road in a column of companies in the order L, K, and I, and met no serious opposition until it reached a cemetery south of Dagami. Overgrown with weeds seven to ten feet high and containing stone crypts built off the ground, the cemetery was divided by a path running east to west. As Company L moved into the burial ground, Company I swung around the right (east) side to come into position for the night. The leading elements of Company L passed through the cemetery and Company I moved into position without incident, but as the 1st Platoon of Company L, the reserve platoon, crossed the path, a headstone tilted back and from the open grave four Japanese opened fire with an American Browning automatic rifle and other small arms. The small arms of the 1st Platoon had no effect and it became necessary to bring forward a flame thrower to burn the enemy out. At the same time the platoon received fire from other open graves, from which the Japanese had removed the bodies. By punching holes through the stone they used the crypts as individual foxholes. The platoon broke into small units and pushed through the cemetery, destroying the enemy forces wherever they could be located. Company K, which followed Company I, placed two platoons abreast behind Company L. As it came through the weeds past the cemetery path a Japanese officer charged on the right flank with his saber and wounded one man before he could be brought down. Since the platoons were also receiving heavy fire from the tombs, the commander of Company K drew his men back to the path where they reorganized. Preceded by a battery of six flame throwers, the men then marched shoulder to shoulder through the cemetery and burnt out the enemy. About 1900 the regiment completed the action and formed its night perimeter. During the fighting, the regimental operations officer, hearing the heavy fire and not being able to communicate with the 3d Battalion headquarters, called Company K direct to ascertain if the Japanese had broken through the American lines. "Hell no," was the reported reply, "we're breaking through theirs and fighting for our bivouac." During the night small infiltration parties of Japanese tried unsuccessfully to penetrate the regiment's defenses, and sporadic artillery fire was received from the hills west of Dagami.
The following day, the 3rd and 1st Battalions advanced through the 2nd Battalion to continue their northern push, successfully entering Dagami without facing significant opposition. After securing the previous headquarters of the 16th Division, the 17th Battalion spent the next two days conducting mopping-up operations and patrolling the Dagami area, effectively establishing contact with the 19th Regiment across the Binahaan River and the 382nd Regiment to the east. Simultaneously, the 32nd Regiment dispatched its 2nd Battalion toward Abuyog, which was successfully captured by midday. By October 31, Company G had further taken control of Baybay, and the 1st Battalion had landed at Panaon to support the 21st Regiment stationed there. As a result, General Arnold’s 7th Division accomplished its objective of capturing the Burauen airstrips and Dagami while linking up with the 96th Division and 10th Corps. This operation resulted in an estimated 4,211 Japanese casualties, with 19 soldiers taken prisoner, while the division incurred 322 killed, 1,064 wounded, and 21 missing. Meanwhile, on October 29, the 381st Regiment executed a tank-supported offensive and ultimately captured Catmon Hill, which would be thoroughly cleared in the following two days. At the same time, Halloran’s 3rd Battalion stormed and secured Kiling, with Dill’s 2nd Battalion arriving shortly thereafter. On the outskirts of the barrio the battalion met stubborn and determined resistance where the Japanese, with machine guns, mortars, and rifles, fought "to the last man." The resistance was overcome, and by 1500 the Americans occupied the town, which was honeycombed with emplacements and entrenchments. At 1600 the 3d Battalion, 381st Infantry, was relieved by the 2d Battalion, 382d Infantry, which had come up from Tabontabon by truck. At 1800 the 3d Battalion, 381st Infantry, returned by truck to the area north of San Roque. However, the remainder of the 382nd Battalion was unable to penetrate the retreating 9th Regiment towards Kiling, allowing some Japanese forces to evade complete destruction. Nevertheless, Bradley’s 96th Division successfully took control of the Catmon Hill mass and the key towns of Tabontabon and Tanauan, resulting in an estimated 2,769 Japanese casualties and 6 prisoners captured, at the cost of 145 men killed, 564 wounded, and 90 missing.
On October 29, Colonel Newman’s 3rd Battalion advanced northward, leading the charge toward Jaro. They gradually battled through Galotan and quickly captured Jaro without much resistance. The American forces moved so swiftly that Suzuki was unable to implement his strategy of using Jaro as the gathering point for the reinforcements of the 35th Army, compelling him to designate Carigara as the new rendezvous site. Due to the evident Japanese strength in the region, Hoffman ordered his units to bolster defenses in Barugo, with the remaining units of the 1st Squadron, 7th Cavalry arriving by nightfall, followed by the 2nd Squadron, 8th Cavalry on October 31, and the 2nd Squadron, 5th Cavalry on November 1.
At 08:00 on October 30 Colonel Newman ordered the 3rd Battalion of the 34th Regiment to start for Carigara down the highway. As the battalion left the outskirts of Jaro, with Company L in the lead, it came under fire from Japanese who were dug in under shacks along the road. Upon a call from the commanding officer of Company L, the tanks came up in a column, fired under the shacks, and then retired. The leading platoon was drawn back so that artillery fire might be placed on the Japanese, but the enemy could not be located precisely enough to use the artillery. Newman then ordered a cautious movement forward without artillery support, a squad placed on each side of the road and two tanks in the center. The squads had advanced only fifty yards when Japanese fire again pinned them down. When Newman came forward and discovered why the advance was held up he declared, "I'll get the men going okay." Upon hearing that the regimental commander was to lead them, the men started to move forward. The Japanese at once opened fire with artillery and mortars, and Colonel Newman was hit in the stomach. Although badly wounded he tried to devise some means of clearing the situation. After sending a runner back with orders to have the 3rd Battalion fire on the Japanese position, he said, "Leave me here and get mortar fire on that enemy position." As soon as possible Colonel Newman was put on a poncho and dragged back to safety.
The following morning, while the 1st Battalion, 19th Regiment moved toward Jaro, the 34th Battalion launched another attack and managed to reach the Yapan River. Despite their fierce assault, the heavy Japanese artillery and flanking fire once again stalled the Americans on their journey to Carigara, allowing the 41st Regiment to withdraw. At this stage, the 5th Air Force had officially set up its forward units on Leyte, tasked with achieving air superiority and attacking Japanese convoys and troop concentrations. However, as the 13th Air Force focused its primary efforts on airfields in bypassed areas.
Poor weather had taken its toll on General Krueger’s advance. Rainy, monsoon-like conditions confounded his engineers, and airfield construction at Tacloban and Dulag floundered. Landing conditions were still poor. Naval carrier aircraft, from damaged escort carriers, headed to both airfields instead of ditching at sea. As the Navy pilots attempted to land on Leyte, 25 out of 72 planes ended up damaged. Without suitable land-based US air power, the Japanese could continue to launch air attacks. Limited American air power did contest the skies against the Japanese, but could still only provide a minimum of close air support to the American troops. While Japanese aircraft continued to reach targets throughout Leyte, Kinkaid and Halsey’s forces had to depart the Leyte region to resupply, so Kenney had to take over with his limited forces. MacArthur did persuade Halsey to maintain Task Group 38.2 in the area when he withdrew most of his fleet on October 29. Kinkaid also left ten escort carriers only by redistributing fleet supplies, but he also had to refit. Nonetheless, Ground commanders criticized Kenney’s continued failure to provide close air support. During the early invasion period, naval carrier aviators had delivered direct support. For example, out of the 121 troop support missions from October 20 to 25, pilots flew 33 sorties in direct support of soldiers. With Kinkaid and Halsey’s forces departed, Kenney’s focus was on air superiority. He had eliminated most close air support missions until later in the campaign. As a result, the infantry had to rely on artillery.
The escort carriers of the 7th Fleet, significantly diminished following the Battle of Leyte Gulf, were unable to provide support. Although Admiral Mitscher’s carriers did conduct numerous strikes against Japanese shipping in the Visayas and Manila Bay in the last days of October, Task Force 38 had mostly been withdrawn by the end of the month. During the final week of October, the 4th Air Army and the newly-formed 1st Combined Base Air Force maintained a persistent campaign to support ground operations, gradually redirecting their attacks from amphibious shipping and carriers to the enemy-occupied airfields at Tacloban and Dulag.
Though Kenney’s airfields still had minimal capacity, he had 34 P-38s from the 49th Fighter Group based at Morotai deployed to Tacloban Airfield on October 27. Three days later, only 20 P-38s remained, as Japanese air attacks destroyed or damaged several of the twin-tailed aircraft. In response, Kenney deployed more P-38s from the 475th Fighter Group. He also assigned six P-61s from the 421st Night Fighter Squadron to counter night attacks. Kenney later replaced them with F6Fs from VMF (N)-541, which improved night patrol and interception missions to include strikes on Japanese night convoys. Thus, Kenney’s pilots, led by the elite aces Richard Bong and Thomas McGuire, started to make a difference. Additionally, bombing attacks disrupted airfield construction and caused aircraft losses since they were parked close together due to space limitations. Still, Army engineers with Filipino labor made inroads towards rendering the airfields fully operational. Pilots could now use an expanded 5,000ft runway at Tacloban on October 31. With a growing 5th Air Force presence, the Americans improved their ability to intercept bombers; as a consequence, the Japanese relied more on night attacks.
This shift inflicted substantial damage and compelled the Americans to reinforce their positions. Alongside the primary air offensive targeting enemy supply shipping and airfields, Kamikaze units executed suicide attacks against enemy carriers operating off the east coast of the Philippines. Pilots, as well as aircraft of various types, were drawn from the 153d, 601st and 761st Air Groups. The initial corps used only bomb-equipped fighters. However, after the reorganizations of the Kamikaze corps, all types of aircraft were used.
A kamikaze suicide aircraft hit Intrepid on one of her port side gun positions; ten men were killed and another six were wounded, but damage was minimal. The USS Franklin had just refueled and returned to the Leyte action on 27 October, her planes concentrating on a heavy cruiser and two destroyers south of Mindoro. She was under way about 100 miles (160 km) off Samar on 30 October, when enemy bombers appeared bent on a suicide mission. Navy fighters shot down most of the Japanese planes, but six broke through the combat air patrol into Franklin's task group of four carriers defensively surrounded by a circle of about twenty escorting cruisers and destroyers. Shipboard anti-aircraft guns shot down three of the four kamikazes independently diving toward each of the four carriers; but the one targeting Franklin hit the flight deck and crashed through to the gallery deck, killing 56 men and wounding 60. As the remaining two kamikazes attacked, one was shot down by anti-aircraft guns and the second missed Franklin with two bombs before flying into the stern of Belleau Wood. Franklin was able to extinguish fires and patch the flight deck so planes could be recovered 76 minutes after the kamikaze hit. Both carriers retired to Ulithi Atoll for temporary repairs, and then Franklin proceeded to the Puget Sound Navy Yard, arriving on 28 November 1944 for repairs of her battle damage.
Meanwhile, on October 30, the 20th Antitank Battalion was successfully landed at Ormoc. The following day, Mikawa dispatched his remaining two echelons: the second comprised three transports carrying the Imahori Detachment, primarily made up of Colonel Imahori Tetsusaku’s 12th Independent Regiment. The third included four transports and four frigates carrying most of Lieutenant-General Kataoka Tadasu’s 1st Division along with around 9,000 tons of supplies and ammunition, all under the protection of Rear-Admiral Kimura Masatomi’s screen of six destroyers. This would be Mikawa’s last convoy, as he would soon be replaced in command of the Southwest Area Fleet by Vice-Admiral Okawachi Denshichi due to his deteriorating health.
Following a smooth journey, the Imahori Detachment was quickly disembarked at Ormoc on November 1, with the remainder of the convoy arriving later that night to commence the unloading for the 1st Division. During the day, one of the transports was sent to Cebu to pick up the 35th Army Headquarters, which landed the next morning alongside Kataoka’s troops. By noon on November 2, a total of 13,000 soldiers had successfully arrived, culminating in the most effective reinforcement operation of the Leyte campaign, with just one transport lost and another slightly damaged. Turning to the primary action, on November 1, two companies from the 34th Regiment were ordered to execute a broad flanking maneuver and then attack Tunga from the northeast, facing no resistance. This enabled Newman’s 1st and 2nd Battalions to advance swiftly down the highway to a point approximately 1,000 yards from Sagkanan. Concerned about the enemy’s considerable presence at Carigara, Sibert planned for his two divisions to launch a coordinated assault on the town the following day; however, unbeknownst to him, the disorganized Japanese forces chose to abandon the town and retreat to the mountains southwest of Capoocan. Thus, following a heavy artillery bombardment, the Americans captured Carigara without opposition and promptly established a perimeter, while the 34th Regiment advanced further to Balud, where they encountered intense enemy fire. On that same day, the 382nd Regiment took control of Dagami, from which they would engage the positions of the 16th Division on Bloody Ridge over the coming days.
The capture of Carigara marked the completion of the second phase of General Krueger's plan for liberating Leyte. Irving's 24th Division successfully achieved its objectives, resulting in the deaths of approximately 2,970 Japanese soldiers and the capture of 13 prisoners, with their own losses totaling 210 killed, 859 wounded, and 6 missing. Additionally, by October 27, Mudge’s 1st Cavalry Division had killed an estimated 739 Japanese and taken 7 prisoners, incurring a loss of 40 men killed, 199 wounded, and 8 missing. The next phase of Krueger’s strategy involved two offensives converging on Ormoc: one moving south through Ormoc Valley led by Sibert’s 10th Corps and the other advancing north from Baybay under Hodge’s 24th Corps. Initially, while certain units of the 24th Corps continued pushing west to bolster troops along Ormoc Bay and clean up in southern Leyte Valley, Sibert’s forces aimed to secure control of the Carigara Bay coastline from Carigara to Pinamopoan. Simultaneously, Suzuki sent the experienced 1st Division to Carigara to launch an offensive toward Tacloban.
The 1st Division, which had been activated in Tokyo, had served in Manchuria during the "China Incident" and had been transferred to Shanghai in August 1944. Though it had no combat experience, this division was considered by Major-General Tomochika Yoshiharu, deputy chief of staff of the 35th Army, to be the best equipped division of the Japanese Army. Under the command of Lieutenant-General Kataoka Tadasu, it had been held in reserve by Imperial General Headquarters for the decisive battle, and it was sent to Manila with great expectations. Meanwhile the Imahori Detachment moved to the northeastern base of the heights southwest of Jaro to facilitate the assembly of the 26th Division for an impending attack on Jaro. After securing Carigara, the 68th Brigade was set to land in the north as part of the 35th Army reserve, while the 30th Division would land at Albuera on Ormoc Bay and negotiate mountainous trails to Burauen to eliminate all enemy resistance in the Dulag region. As other units of the 102nd Division were moved forward using powered schooners, a reinforced company from the 364th Independent Battalion was also deployed to Albuera to secure the landing site for the 30th Division.
On the morning of November 3, the 34th Regiment moved west once again and quickly seized Capoocan, just as Kataoka's vanguard was getting close. Suzuki immediately approved the emergency dispositions already taken and issued orders temporarily attaching the various reinforcement units to the 1st Division. It was impossible, however, to notify Lt. Gen. Kataoka immediately of the changed situation, and the division advance guard moved into the vicinity west of Capoocan at 0900 on 3 November to find itself unexpectedly engaged by the enemy. Badly surprised, the advance guard fell back toward Colasian with the enemy in pursuit. Meanwhile, at 1000, Lt. Gen. Kataoka reached the high ground south of Managasnas. Finding his advance guard engaged, he immediately ordered the 1st Reconnaissance Regiment and the 20th Antitank Battalion to check the enemy advance. At the same time he dispatch ed an order to the division main body to close up at forced march. Although the defenders were initially taken by surprise, they managed to halt the enemy's progress with fierce resistance, ultimately compelling them to withdraw. It was only after artillery bombardment of the ridge parallel to the road that the 34th finally dismantled the Japanese stronghold, establishing their position for the night. Additionally, earlier in the day, Company K had conducted a reconnaissance mission using amphibian tractors from Capoocan to a location just west of Pinamopoan. However, due to heavy enemy fire, the company withdrew and returned to Capoocan. Unbeknownst to the Americans, Kataoka mistakenly perceived this as a battalion-sized enemy assault, prompting him to retreat southwest and position his forces on the eastern end of a long ridge overlooking the coast, referred to as Breakneck Ridge.
Breakneck Ridge, over which Highway 2 corkscrewed its way between Pinamopoan and Limon for about 7200 yards, was actually a hill mass with many spurs branching off from an irregularly shaped crest line toward the shores of Carigara Bay to the north and the Levte River valley to the south. Shoulder-high cogon grass was thick on the low ground, and the pockets between the hills were heavily forested. The valleys were deep, with precipitous sides. The 1st Division had heavily fortified the area, taking advantage of the innumerable thickly wooded pockets that served as natural forts. The Japanese had also built an elaborate system of trenches and other defensive positions and had honeycombed the area with spider holes. Many of the latter were on reverse slopes some distance below the crests and were protected from direct fire. In front of each spider hole the enemy had cut fire lanes through the cogon grass, which was left so short that even a crawling soldier would be exposed to fire. The constant rainfall made the hills slippery and treacherous, and, more important, provided a protective curtain in the day and covered movements of the enemy at night.
Following the Japanese withdrawal, the 34th quickly secured Colasian and captured Pinamopoan without opposition the next day. Newman’s 3rd Battalion advanced through the town, continuing west along the highway for about 1,700 yards, stopping just short of the ridge. Anticipating a potential enemy amphibious assault via Carigara Bay, Krueger ordered Sibert to defend the Carigara area against any seaborne attack before proceeding southward. Meanwhile, as the divisions of the 10th Corps prepared defensive measures against a possible sea invasion, Colonel Miyauchi Yoshio’s 57th Regiment was ordered to get ready to launch an attack from the ridge, as Kataoka believed that the enemy force could be easily cut off.
As the newly-arrived 21st Regiment took over from the 34th at the Pinamopoan defenses, the Japanese forces launched an attack on a party of artillery forward observers conducting reconnaissance on OP Hill on November 5. With the artillerymen pinned down, Lieutenant-Colonel Frederick Weber's 3rd Battalion moved in to assist them by the afternoon, successfully securing the northern approaches to OP Hill and the undefended Corkscrew Ridge on the left. Although the Americans were able to fend off the enemy's counterattacks, intense mortar fire on November 6 ultimately compelled them to withdraw. Despite suffering heavy casualties during the battle for Breakneck Ridge, the 1st Division had nearly completed its concentration in the Cananga area and was ready to initiate a broad four-pronged assault. However, the Japanese advance through the mountainous terrain remained exceedingly slow, leaving the 57th Regiment to conduct the attack on its own. Concurrently, Irving attached the 3rd Battalion of the 19th Regiment to the 21st Regiment and ordered the combined force to advance towards Breakneck Ridge. Consequently, Weber's troops launched an assault on Miyauchi's positions, but were completely unsuccessful in breaking through. Dissatisfied with the 21st Regiment's progress and feeling that Weber was insufficiently aggressive, Sibert replaced him with Lieutenant-Colonel William Verbeck, a seasoned veteran of the Alaska Campaign. Verbeck then made an unsuccessful attempt at a wide flanking maneuver to the east but ultimately had to entrench at the edge of Breakneck Ridge by nightfall. On the same day, Colonel Chapman dispatched Company G to Hill 1525, but it lost its way and ended up considerably further east.
Thats all we have for today on the Philippines front as we now need to shift over to New Britain. In October, a decision was made to deploy the 40th Division for combat in the Philippines, transferring control of the island to the Australians. This change aligned with the Australian government's intention to utilize their own troops to reclaim territory previously occupied by the Japanese during the war. As a result, General Ramsay’s 5th Division began relocating to New Britain, tasked with containing and isolating the Japanese garrison on the Gazelle Peninsula. Ramsay was instructed to maintain pressure on the Japanese forces while avoiding large-scale deployments, permitted only to conduct patrols and minor raids as limited offensive actions. By late October, the 36th Battalion had assumed control at Cape Hoskins, with the remainder of the 6th Brigade slated to land at Jacquinot Bay in early November.
At this time the Japanese had posts at intervals along the south coast as far west as Awul near Cape Dampier. It was decided that the Australian southern guerilla force would be based at Lakiri, a village in the hills two days' march inland from Waterfall Bay, and in an area into which the enemy had not ventured. It possessed a good site for dropping stores from the air and, as a preliminary, some 25,000 pounds of supplies were dropped there. To give added security to the base the Australian-led native guerillas, commanded at this stage by Captain R. I. Skinner, overcame the enemy's coastwatching posts at Palmalmal and Baien, to the south-west and south-east, respectively, killing 23 and taking three prisoners. None survived at Palmalmal, but two escaped from Baien, and it was learnt later that they reached an enemy post at Milim bearing news of what had happened. The south coast group was now placed under the command of Captain Basil Fairfax-Ross, who counted with five officers, 10 Australian N.C.O's, about 140 native troops, and such native allies as could be maintained on an air delivery of 5,000 pounds of supplies a month.
After the loss of Baien the Japanese reinforced their post at Milim at the south end of Wide Bay until it was 400 strong. Far to the west they retained posts at Massau and Awul and round Cape Beechey. Fairfax-Ross decided to move discreetly into the strongly-held Wide Bay area, advancing through the hills, concentrating first on winning over the natives , and using the air power available from Bougainville as his trump card . At the same time spies would be sent into the Gazelle Peninsula. In the western area also the first task was to gain information. On 5th June an American patrol from the west led by Lieutenant White of Angau attacked the Awul garrison, which withdrew inland. An Australian platoon under Lieutenant Black thereupon marched from Jacquinot Bay to Lau and Atu. In this area they found that native guerillas about 80 strong had killed 14 Japanese and 14 of their native allies. At Awul they met White and his party. It now seemed that the Japanese from the Atu-Awul area were retreating to the north coast. Guerillas were organized and at Kensina on 18th June, "after pretending to entertain a party of about 50 enemy" , the natives attacked and killed 28, losing 5 of their own men. Black's patrol, in pursuit, found the remainder of the enemy about Rang and i n an attack on 24th June killed nine, but had to withdraw after losing one native N.C.O . As they moved north and east through hostile territory other Japanese were killed. In the eastern section in this period Lieutenant Johnson was winning the support of influential natives in the mountains south-west of Wide Bay. A heavy air attack was made on the main Milim positions on the night of 17th-18th July and as a result the Japanese with- drew some men to a new position away to the west and some men right back to Lemingi in the Gazelle Peninsula. By early September the last of the Japanese stragglers on the south coast west of Wide Bay had been killed; the Japanese had heard many reports of a strong Australian base at Jacquinot Bay-reports circulated by the Australians to dissuade the enemy from advancing westward. This base, although non-existent as yet, was soon to become a reality, and from 5th to 7th September a reconnaissance party, including officers from New Guinea Force and the 5th Division, landed from the corvette Kiama and, guided by Black, examined the area.
The two-platoon force reached Milim unnoticed on 12th August, and found the enemy about 150 strong. At dawn they opened an attack in three groups, one to fire on the houses in the Japanese camp, another to fire from the flank, and the third to intercept any reinforcements from the Yaret position 500 yards to the north. Unfortunately a native fired his rifle during the approach, the enemy manned his defenses, and, after a short exchange of fire, the attackers withdrew and placed ambushes across the tracks. The same day the Swan bombarded Milim. After three days of inaction on the part of the Japanese four native soldiers crawled into the enemy's position and killed three, whereafter the Japanese fired into the bush at intervals for 36 hours. This fire ceased on the 18th and soon afterwards the position was found to be abandoned; there was much booty including boats and numerous machine-guns. It was discovered that the enemy had withdrawn to Waitavalo. Fairfax-Ross now moved his forward base to the coast at the Mu River only 6 hours' march from Waitavalo. On 17th and 18th September Fairfax-Ross, Sampson and a platoon, reconnoitring Kamandran, became involved in a fight with a Japanese force about 100 strong. Anticipating that the enemy would retaliate in force the Australians prepared defensive positions and one platoon under Sergeant-Major Josep, an outstanding N.C.O. who had come from the New Guinea Constabulary, was placed on the hillside above Milim to give warning of an enemy advance. On the night of 28th September the Japanese did in fact advance on Milim and on towards the Australian defensive position at the Mu River. Here, however, largely because of Sergeant Ranken's cool handling of his Bren gun, they were repulsed, losing 17 killed. Next day about 200 Japanese reinforcements arrived and, in a firefight with Josep's men whose presence they had not discovered, 16 Japanese and a native ally were killed. The Australians now withdrew inland. Soon the Japanese, about 700 strong, were in their original positions round Milim, where they remained until heavy air attacks on 6th, 7th and 8th October forced them out again. By 10th October the guerilla force was again concentrated at Lakiri. Consequently, on November 4, a small convoy landed the reinforced 14th/32nd Battalion at Jacquinot Bay without encountering any resistance. In the days following the landing, ground forces secured the Jacquinot Bay area, while a New Guinean company executed an amphibious operation to Pomio on November 6.
The 6th Brigade was gradually transferred to Cutarp, with the final units arriving on December 16. Due to shipping shortages and the low priority for reinforcing forces on New Britain, all components of the 5th Division would not advance to Jacquinot Bay until April 1945. The first echelon of the 13th Brigade arrived on November 26, while the remaining units followed by the end of December. Meanwhile, in the north, the 36th Battalion dispatched patrols to connect with Australian guerrillas at Ulamona, Ubili, and Ea Ea, aiding them in fending off an enemy advance on the Balima River by the end of November.

The Americans were making tremendous progress in the Philippines, advancing through the Ormoc Valley. Despite the terrible odds, it seems the Japanese would not give up an inch of territory without a fight, digging their heels to the very end. Meanwhile the Australians were dealt mop up duty on New Britain and it was going equally as well.

29 10月· The Pacific War - week by week
Last time we spoke about the Battle of Leyte Gulf. General MacArthur's forces landed on Leyte, prompting a response from Admiral Toyoda. Kurita's 1st Striking Force was sent to attack Leyte Gulf, while Shima's force faced confusion and delays. Japanese naval forces were hit hard by American submarines, with significant losses including the sinking of the Atago and Maya. Despite efforts, Japanese counterattacks faltered. On October 24, American forces secured key positions, and MacArthur announced the re-establishment of the Philippine government amidst ongoing naval battles and air attacks. During the fierce Battle of Leyte Gulf, Musashi endured multiple torpedo and bomb hits from American aircraft but continued to fight as it took on severe flooding. Despite efforts from Kurita's fleet, Musashi was eventually abandoned and sank, marking the largest ship ever sunk by air attack. Nishimura's force faced relentless torpedo strikes and a decisive night battle, with the battleship Fuso and cruiser Mogami being heavily damaged or sunk. Ultimately, Nishimura's forces retreated, and the Americans achieved a significant victory.
This episode is the Last Carrier Battle

If you are still hungry for some more history related content, over on my channel, the Pacific War Channel you can find a few videos all the way from the Opium Wars of the 1800’s until the end of the Pacific War in 1945.
Where we last left off during the Battle of Leyte Fulg, the 10th and 24th Corps had established successful beachheads at Palo-Tacloban and Dulag. In response, Admiral Toyoda launched Operation Sho-Go, mobilizing the full strength of the Imperial Japanese Navy to eliminate enemy warships and transports at sea. However, after losing three heavy cruisers to submarines, Admiral Kurita’s 1st Striking Force faced severe damage from Admiral Mitscher’s Task Force 38, culminating in the sinking of the battleship Musashi by the end of October 24. Shortly after the Sibuyan Sea engagement, Admiral Nishimura’s Force C was annihilated by Admiral Kinkaid’s 7th Fleet at the Surigao Strait. Despite these setbacks, Admiral Shima’s 2nd Striking Force was approaching the area. Meanwhile, the Americans had identified Admiral Ozawa’s decoy force by the end of the day. In response, the aggressive Admiral Halsey chose to leave San Bernardino Strait unguarded and pursue the depleted Japanese carrier force to the north, aiming to finish off the IJN. Unknown to him, Kurita, with four battleships, six heavy cruisers, two light cruisers, and several destroyers, was advancing towards San Bernardino Strait to attack Kinkaid’s transports and escort carriers from the rear. This set the stage for one of the final and largest naval battles of the Pacific War. To the north, as the Battle of Surigao Strait was in progress, radar-equipped aircraft from the Independence detected Admiral Matsuda’s battleship carriers and later Ozawa’s carriers in the early hours of October 25. However, due to a transmission error, the location of the Japanese forces was reported inaccurately. After the rendezvous of three of Halsey’s four carrier task groups just before midnight on October 24, TF 38 headed north with every expectation of achieving a great victory. At 0100hrs on October 25, five radar-equipped aircraft flew off Independence to search out to a distance of 350NM. Contact was gained at 0205hrs on Force A and at 0235hrs on the Main Body. Because of a transmission error, the position of the Japanese forces was given incorrectly. The wrong position was plotted out some 120NM nearer to TF 38 than it actually was. In fact, TF 38 and Ozawa were actually about 210NM apart.
Despite this, Mitscher's carrier was readying for morning strikes while Admiral Lee’s Task Force 34 was being reorganized. Meanwhile, Kurita’s 1st Striking Force surprisingly navigated through San Bernardino Strait during the night without encountering resistance, proceeding towards Leyte Gulf and a confrontation with Rear-Admiral Thomas Sprague’s escort carriers near Samar. However, the movement of Shima’s force was not coordinated with Nishimura’s. Shima designed his advance so he could attack separately from Nishimura’s force. The gap between the forces was originally five hours, but Shima reduced this to two hours by the time his force began entering the strait. As he entered Surigao Strait on the night of October 24/25, Nishimura issued reports during the early part of his transit, which Shima received, but when he met serious resistance, the reports stopped. Shima was therefore unaware of the virtual annihilation of Nishimura’s force. The only information available was gunfire flashes in the distance and snippets of radio traffic from Nishimura’s ships under attack. Oldendorf was aware that a second force was moving to support Nishimura. The first firm indication of this was a contact report from the PT boats on Shima’s force at 0038hrs. Oldendorf knew he was dealing with two widely spaced Japanese forces. Just as Nishimura was forced to deal with incessant PT boat attacks, now it was Shima’s turn. These turned out to be more than a mere nuisance. Shima’s introduction to combat came at about 0315hrs when PT-134 mounted an ineffective attack.
One PT boat managed to hit the cruiser Abukuma with a torpedo at 03:25, causing a significant explosion and slowing her to 10 knots, forcing her to exit Shima’s formation. As Shima advanced, he observed several ships ablaze and saw the destroyer Shigure retreat before detecting a radar contact 13,000 yards away. Without Shima’s approval, his chief of staff ordered the two cruisers to maneuver for a torpedo strike against the distant and indistinct radar contacts. At 0422hrs Nachi and Ashigara each fired eight Type 93 torpedoes at the radar contacts. In fact, these were Oldendorf’s flagship Louisville followed by Portland. Despite the element of surprise, the Japanese torpedo attack completely failed. Immediately after firing its torpedo broadside, Nachi faced disaster. The burning Mogami had loomed out of the darkness minutes before. Nachi’s skipper failed to grasp that Mogami was underway, not stationary, and he failed to take proper measures to avoid the damaged cruiser. As Nachi was unable to pass forward of Mogami, the two ships side-swiped each other forward at 04:23. Frantic last-second maneuvers lessened the impact of the collision, but the result was still dramatic. Nachi took the worst of it, suffering a large gash in her bow at the waterline on her port side. Damage to the bow reduced her speed to 18 knots. Shima’s four destroyers then continued north but failed to locate any targets. Fearing inevitable destruction, Shima decided to retreat south at 04:35. Although Oldendorf had dispatched his cruisers and destroyers to pursue the fleeing Japanese, his forces did not aggressively pursue, allowing Shima to escape.
In the end, Oldendorf’s pursuing cruisers only managed to catch the damaged Mogami and Asagumo, which they unsuccessfully attacked at 05:29. Despite sustaining additional hits, the Mogami continued to fight, escorted southwest by the destroyer Akebomo. The Asagumo, however, came under attack again at 07:02 and sank 19 minutes later. As Asagumo slipped under the waves, all that was left of Nishimura’s force were hundreds of survivors in the water. Rescue efforts by at least four American destroyers resulted in only a handful being picked up. When one of Oldendorf’s destroyer skippers asked at 07:35 what to do with the hundreds of men still in the water, Oldendorf simply replied, “Let them sink.” Japanese survivors who reached shore were, in many cases, killed by local inhabitants.
While it seemed the Mogami might escape, Sprague’s Taffy 1 group carriers launched their first strikes before 06:00. Four Avengers attacked the cruiser at 07:41 but failed to score any hits. Around 08:40, 21 aircraft also targeted Shima’s force, but only inflicted minor strafing damage on the destroyer Shiranuhi. Before Sprague could continue his air attacks, new developments were occurring off Samar as Kurita’s warships approached Rear-Admiral Clifton Sprague’s Taffy 3 group. At 06:44, a lookout from the Yamato made visual contact, though he mistakenly identified the escorting destroyers as heavy cruisers and battleships. Kurita’s initial orders increased the confusion generated by the first contact at 06:44. He ordered “General Attack” at 07:03, meaning that each ship or division proceeded on its own against the Americans. This tactic abandoned any pretense of coordination between the various elements of the 1st Striking Force. Battleships Yamato and Nagato remained together, but Kongo and Haruna operated individually. For most of the engagement, the six heavy cruisers operated in three groups of two. The two destroyer flotillas, each led by a light cruiser, were kept to the rear by Kurita. He held his destroyers back to maintain their fuel reserves by not having them maneuver at high speeds, instead sending his heavy cruisers ahead to pursue at full speed. This precluded them from screening the heavy ships and kept them out of position to make a torpedo attack. The General Attack decision was a critical error. It resulted in a loss of control by Kurita and a melee for the next two hours. His rationale for ordering an immediate, but uncoordinated, attack was to close the range as quickly as possible and knock out the carriers’ flight decks. Throughout the battle, Kurita maneuvered to keep the weather gauge; by so doing, he could prevent the carriers from turning into the wind to conduct flight operations. Meanwhile, an Avenger from Kadashan Bay sighted Kurita’s force at 06:47 following radar contacts. Despite his surprise, Sprague immediately ordered Taffy 3 to head east, increased speed to 17.5 knots, directed every ship to lay smoke, and launched all available aircraft at 06:55. Realizing the gravity of the situation, Sprague began sending clear text messages at 07:01 to report his predicament and request assistance.
Sprague's main objective was to delay the Japanese forces until reinforcements could arrive. To achieve this, he decided to use smoke screens and continuous air assaults, supported by Taffy 2’s aircraft, to hinder Kurita’s ships. As Kurita’s cruisers advanced north, Sprague opted to maneuver southwest, moving closer to Leyte Gulf and the potential assistance from the 7th Fleet. Starting at 06:59, Kurita’s battleships began firing from long range, with their salvos becoming more frequent and accurate. To mitigate this pressure, Sprague directed his forces into a rain squall from 07:06 to 07:15. Once clear of the squall, he changed course southward towards the approaching help from Leyte Gulf. Meanwhile, as Kurita’s ships continued east before turning south, the range of Sprague’s carriers was extended, and the rain and smoke impaired the accuracy of the Japanese gunners. Sprague also ordered his three destroyers to launch a torpedo counterattack to shield the escort carriers as they emerged from the squall. The Johnston, charging through enemy fire, engaged the cruiser Kumano with gunfire to close the distance for a torpedo attack. At 10,000 yards, the Johnston fired all ten of its torpedoes, scoring a critical hit that slowed the cruiser and forced it to retreat. It was inevitable that Evans would pay a price for approaching so close to a collection of enemy cruisers and battleships. This came at 0730hrs in the form of three large shells (possibly fired from Yamato) and a number of smaller shells that struck Johnston. The armor-piercing shells failed to explode, but damage was extensive. The aft machinery room was destroyed, which reduced speed to 17 knots. Most of the 5in./38 guns were knocked out, but after repairs were made during a providential 10-minute respite as a squall passed over, three were brought back online. The battleship evaded the torpedoes at 07:33 and retaliated with devastating gunfire against the Hoel.
By 07:30, all operational aircraft were airborne, prompting Sprague to order the initial attacks on the heavy cruisers approaching his port quarter. Unrelenting American air attacks were the main reason for the Japanese defeat. Taffy aircrews were not highly trained for maritime attack, and torpedoes or armor-piercing bombs were in short supply. Most Avengers were launched with bombs instead of more effective torpedoes for two reasons. Torpedoes took more time and preparation to load, and the deck crews on Taffy 3 did not have the luxury of time. Also, once loaded with a heavy torpedo, the Avengers could only be launched if the escort carrier steamed into the wind. Moving downwind, like Taffy 3 was forced to do for most of the action, did not get enough wind across the flight deck. The first attacks by Taffy 3 aircraft were conducted in groups of two or three with aircraft not properly armed for attacking ships. Because Taffy 3 could not steam into the wind while being pursued by Kurita’s force, recovering aircraft during the battle was impossible. When they ran out of ordnance or fuel, they had to land on Taffy 2 or fly 100NM to the newly opened airfield at Tacloban. Even when lightly armed or unevenly unarmed, the aircraft made unceasing strafing runs in the case of the Wildcats or dummy bombing runs in the case of the Avengers. These attacks were poorly coordinated, but the Japanese, on the receiving end of incessant attacks, saw it differently. After the battle, Kurita and others commented that the attacks were well coordinated, skillful, and aggressive.
At 07:35, ten Avengers struck the cruiser Suzuya just as Vice-Admiral Shiraishi Kazutaka was boarding, scoring a near miss that reduced her speed to 20 knots and took her out of the battle. The damaged Hoel then attempted a second torpedo attack on the heavy cruiser Haguro at 07:50 but failed to hit the target. However, this attack forced the Superbattleship Yamato to open fire at 0659hrs. Her third salvo straddled White Plains, with one of the shells striking the carrier and causing some underwater damage. Around 0800hrs, to evade torpedoes fired from Hoel aimed at Haguro, Yamato turned due north. This evasive maneuver forced her to the north for almost ten minutes until the torpedo tracks disappeared, placing her at the rear of Kurita’s formation and effectively removing her from the battle for a period. Nagato opened fire at 0701hrs at a carrier assessed to be 36,000 yards away. After the three salvos, the battleship stopped firing having hit nothing.
At 07:54, the Heermann launched seven torpedoes at Haguro, but they missed. Destroyer escorts Samuel B. Roberts, Raymond, and Dennis also joined in the attack but also failed to score hits, though they managed to escape unharmed. The Heermann subsequently launched a second torpedo attack on the Haruna at 08:00, but once again, none of the torpedoes hit their mark. Despite using smoke and evading shell splashes, the Heermann avoided damage. The first ship to succumb to the barrage of Japanese shellfire was the crippled Hoel. After her run against Haguro, and only able to make 17 knots, she was trapped between Kongo on one side and four heavy cruisers on the other. Using every possible method to evade the storm of shells directed against his ship, Kintberger survived for well over an hour after the first hit was recorded. Hoel took as many as 23 hits, but the actual number will never be known since most passed through the ship without exploding. The final engine was knocked out at 0830hrs, bringing the ship to a halt. As the crew abandoned ship under continued fire, the Hoel finally rolled over at 08:55. Meanwhile, the Japanese cruisers continued to close in on the escort carriers. Under fire from the battleships, Sprague’s initial course was to the eastsoutheast at full speed—17.5 knots. As the Japanese heavy cruisers began to pressure his formation’s port quarter, Sprague was forced to alter course to the southwest. Kalinin Bay was at the rear of the formation. She took a battleship shell at 0750hrs (probably from Haruna) that went through the hangar deck and out of her unarmored hull. As many as 14 other hits followed, all probably from 8in. shells. Kalinin Bay retaliated against the cruisers at 18,000 yards with her aft 5in./38 gun. The smoke generated from all six carriers and from the destroyers and destroyer escorts on their starboard quarter succeeded in hiding the carriers from direct Japanese observation for much of the battle. The Japanese shot slowly and methodically with four-gun salvos, allowing the escort carriers to chase salvos. The smoke and evasive maneuvering kept damage to a minimum, but of the six escort carriers, four were eventually hit. Fanshaw Bay took six 8in. hits, all forward, that killed three and wounded 20. White Plains took a probable 6in. hit and suffered light damage. Kitkun Bay was not hit but suffered several personnel casualties from near misses. St. Lo suffered no damage during the battle.
The Gambier Bay bore the brunt of enemy fire, with an initial shell igniting a fire at 08:10. Ten minutes later, a devastating hit reduced her speed to 11 knots and forced the carrier to lag behind the rest of the formation. At 08:22, Yamato reentered the fray, intensifying the assault on the carrier. Heermann closed on the carrier at 0841hrs to find her burning and listing 20°. Continued Japanese fire resulted in more hits, with most of the armor-piercing shells passing through the ship. Hit by as many as 26 shells from Yamato, Haruna, and several cruisers, Gambier Bay went dead in the water at 0845hrs; five minutes later, the captain gave the order to abandon ship. Gambier Bay capsized at 0907hrs, one of only two carriers sunk by gunfire during the entire war.
Meanwhile, at 08:26, Sprague ordered the destroyer escorts on the starboard side of the formation to position themselves between the carriers and the Japanese heavy cruisers on their port side. As John C. Butler and Dennis engaged the enemy cruisers, the latter sustained minor damage from two hits. Samuel B. Roberts also was struck at 0850hrs. At 0900hrs, the destroyer escort was hit by two or three 14in. shells from Kongo. The large shells tore a huge hole in the side of the ship and knocked out all power. A total of six shells hit the ship. This prompted an order to abandon ship at 0910hrs for the crew of 178. Half (89 of them) did not survive. Samuel B. Roberts sank at 1005hrs.
During this time, Rear-Admiral Kimura Masatomi instructed his destroyers to launch a torpedo attack at 08:45, targeting Kalinin Bay. Fortunately, Johnston detected the new threat and made a daring suicide charge through the smoke. Evans engaged Yahagi with gunfire at 7,000 yards, and several hits were gained. Then Evans engaged the next destroyer in column, again claiming several hits. Kimura ordered his torpedoes fired from about 10,500 yards—not an ideal range for even the formidable Type 93. Yahagi launched seven torpedoes at 0905hrs, followed by three destroyers beginning at 0915hrs, Urakaze fired four, Isokaze eight, and Yukikaze four. Evans may have been responsible for Kimura’s premature torpedo attack, but now his ship was about to pay the ultimate price. The Japanese destroyers and Yahagi took Johnston under fire, joined by as many as three heavy cruisers. The hits began to pile up. By 0920hrs, Evans was reduced to conning the ship by yelling orders through an open hatch on the fantail to men below turning the rudder manually. At 0945hrs, Evans finally gave the order to abandon ship. The Japanese destroyers closed in and continued to pound the wreck. After an epic fight, Johnston rolled over and sank at 1010hrs. Most of the crew of 327 got into the water, but 186, including Evans, were lost. Meanwhile, Rear-Admiral Felix Stump’s Taffy 2 group began their strikes against Kurita’s fleet, with 15 Avengers and 20 Wildcats successfully hitting the Haguro with a bomb at 08:25.
Five minutes later, six Avengers and 20 Wildcats from Taffy 3 joined forces with 16 Avengers and 8 Wildcats from Taffy 2 to launch a major assault on the enemy cruisers. At 08:50, the Chokai was attacked, and by 09:05, it had sustained severe damage from a bomb hit. The destroyer Fujinami arrived to assist at 10:18, but by then, the cruiser was immobilized. The destroyer evacuated the crew and sank the Chokai with torpedoes. At 08:54, four Avengers targeted the Chikuma, landing a critical torpedo hit that caused significant flooding. With American aircraft focusing on the Japanese warships, Kurita decided to withdraw at 09:11, planning to regroup and return to Leyte Gulf. Another attack against Suzuya was mounted at 1050hrs by as many as 30 aircraft. This time, a near miss amidships turned deadly. Shrapnel from the bomb ignited the torpedoes in the starboard forward mount, igniting a fire that caused other torpedoes to explode at 1100hrs. The explosion caused extensive damage to the secondary battery and the machinery, which left the ship unmaneuverable. For a second time in the morning, Vice Admiral Shiraishi had to transfer, this time to Tone. The fires reached the remaining torpedoes, with a large explosion resulting at 1200hrs. In turn, this caused the magazine of the secondary battery to explode, and soon the entire ship was an inferno. Surviving crewmen were taken off by destroyer Okinami after the order to abandon ship was given at 1300hrs, and at 1320hrs Suzuya sank. Twohundred forty-seven men were lost. The Tone suffered a bomb hit at 12:40, and three minutes later, Noshiro experienced minor damage from near misses. The destroyer Nowaki was tasked with rescuing Chikuma’s crew and then scuttling the crippled cruiser, which was completed by 11:00. Due to these air attacks and fearing total destruction if the battle continued, Kurita signaled Toyoda at 12:36 to abandon the attack on Leyte Gulf and began his retreat north. During this withdrawal, Kurita’s force faced attacks from 37 Avengers and 19 Wildcats at 12:45, resulting in only minor damage to Nagato and Tone. Subsequent strikes by Stump’s carriers were also ineffective, but Sprague’s carriers' total of 441 sorties that day was a notable accomplishment.
At 13:15, 100 aircraft from Admiral McCain’s carrier, which had been recalled on October 24 and were now arriving in the area, launched one of the longest carrier strikes of the war. Despite their efforts, they were unable to inflict additional damage. A follow-up strike at 15:00 with 52 planes also failed, allowing Kurita to escape. Tremendously outgunned, the commander of Taffy 3, Rear Admiral Clifton Sprague, began to plead for help minutes into the battle. As Kurita pressed his advantage, these pleas became more urgent. In response, Oldendorf recalled his advance guard at 0723hrs. Kinkaid ordered Oldendorf to bring his entire force north at 0847hrs to assist the escort carriers. He formed a task force of the battleships California, Tennessee, and Pennsylvania, because they had the most armor-piercing shells remaining. They were escorted by three heavy cruisers and 20 destroyers with 165 torpedoes. The next strike consisting of ten Avengers, each with two 500lb bombs instead of torpedoes, escorted by five Wildcats, all from Ommaney Bay, went after Mogami. The Avenger pilots claimed five hits on the cruiser; in fact, only two bombs struck the ship. By the time the attack concluded at 0910hrs, Mogami was dead in the water after the failure of her last turbine. New fires raged beyond control and the danger of the forward 8in. magazine exploding (the others had been flooded) put the entire crew in danger. After evacuating the remaining crew, the Akebono scuttled Mogami at 13:07, resulting in the loss of 191 men.
Additionally, in the morning, Taffy 1 faced Admiral Onishi’s first kamikaze attack. The first ship to be attacked was Santee. At 0740hrs, a kamikaze commenced its dive, gained complete surprise, and encountered no antiaircraft fire before hitting the ship forward on the flight deck. Fires from the resulting explosion were quickly put out, but not before 43 men had been killed or wounded. Within five minutes of the fires being extinguished, submarine I-56 slammed a torpedo into the ship. The converted tanker shook it off with no casualties and no loss of capability. The final aircraft also selected Petrof Bay but ended up going after Suwannee after it was damaged by antiaircraft fire. It struck the carrier on the flight deck forward of the aft aircraft elevator. The Zero’s 551lb bomb exploded, creating a hole on the hangar deck. The fires were put out within minutes, and within two hours flight operations had resumed. The suicide pilots approached the remaining five escort carriers at low level before popping up to altitude a few miles from their target. At this point they were detected on radar, but no interception by defending Wildcats was possible. At 1049hrs, Kitkun Bay was attacked by a single Zero. The pilot failed to hit the carrier’s bridge, but his aircraft hit the port-side catwalk before crashing into the sea. The ship incurred damage when the Zero’s bomb exploded close alongside. Two more suicide aircraft were dispatched by antiaircraft fire. The last two Zeros selected White Plains for their attentions. One came in from astern but missed the ship after crashing into the water close aboard the port side. The other was deterred by antiaircraft fire and headed toward St. Lo. The last kamikaze was the most skillful. At 1053hrs, the Zero came in over the stern of St. Lo and dropped his bomb before performing a shallow dive into the flight deck amidships. The aircraft slid off the bow, leaving a trail of fire on the flight deck from its fuel. The fire was no problem to deal with, but the bomb penetrated the flight deck and exploded in the hangar deck, where six aircraft were being fueled and armed. The resulting explosion forced the ship to be abandoned, and 32 minutes after being struck, the ship sank with 114 crewmen after the fires reached its magazines. St. Lo was the first ship sunk by kamikaze attack. At 1110hrs, another four kamikazes appeared and selected Kalinin Bay for attack. Two were shot down by antiaircraft fire. The other pair both scored glancing hits. One Zero was hit by antiaircraft fire, remained in control, and then hit the flight deck at a shallow angle and slid overboard. The second hit the ship with a glancing blow aft.
Looking north, despite losing contact with Ozawa’s force overnight, Mitscher decided to launch an initial strike of 130 aircraft, led by Commander McCampbell, by 06:00. At the same time, he dispatched search aircraft, which reestablished contact with Ozawa’s now reunited Main Body at 07:10. The American strike was then directed toward the enemy, and McCampbell’s planes successfully located Ozawa’s carriers at 08:10, beginning their assault. Despite encountering 13 Zeros on combat air patrol, the Helldivers struck first at 08:30, targeting the enemy carriers. They were followed by strafing Hellcats and torpedo-armed Avengers. The hour-long attack resulted in significant damage: Zuikaku was hit by three bombs and one torpedo, leading to fires, flooding, and a severe list; Zuiho sustained a single bomb hit causing fires on the hangar deck; Chitose was heavily damaged by three near misses that ruptured its unarmored hull, causing flooding and a severe list, and it sank at 09:37 with 904 casualties; the light cruiser Tama was torpedoed and had to make its way to Okinawa for repairs; the cruiser Oyodo suffered light damage from a bomb hit; and the destroyer Akizuki was hit amidships, caught fire, and broke apart before sinking following a major explosion. As this attack unfolded, Mitscher launched a second wave of 36 aircraft, which arrived at the target area around 09:45. Under McCampbell’s coordination, these planes focused on the carrier Chiyoda, which was hit by one bomb and several damaging near misses that caused flooding and a list, ultimately bringing the carrier to a halt.
Simultaneously, he deployed search aircraft, which reestablished contact with Ozawa’s now reunited Main Body at 07:10. With the American strike directed towards this position, McCampbell’s planes successfully located the enemy at 08:10 and began their assault on Ozawa’s carriers. The Japanese were aware of the impending arrival of the initial strike, since radar aboard Zuikaku had detected the American aircraft at 08:04 about 110NM to the southwest. Four Zeros were already on CAP; these were joined by the last nine fighters on Zuikaku. Such a meager CAP meant that survival of Ozawa’s ships depended on their ability to throw up accurate anti-aircraft fire and maneuver adeptly under dive-bombing and torpedo attack. According to American pilots, Japanese anti-aircraft fire was heavy and began with a display of multi-colored explosions at 15NM out as Ise and Hyuga fired sanshiki-dan incendiary shells from their 14in. main battery. The small Japanese CAP raced toward the approaching American formation, but the escorting Hellcats prevented them from reaching the Helldivers or Avengers. Essex Hellcats claimed nine Zeros, but one Hellcat was shot down and its pilot left in the water to witness the unfolding attack; he was rescued after the battle.
The Helldivers launched the initial attack on the enemy carriers at 08:30, followed by strafing runs from Hellcats and then torpedo attacks from Avengers. Zuikaku came under attack from dive-bombers and torpedo bombers from Intrepid, and two light carriers. Five minutes into the attack, Zuikaku was hit by three bombs amidships, which created a fire on the lower and upper hangar decks. Just minutes later, a torpedo launched by an Avenger from either Intrepid or San Jacinto struck the ship on her port side. One of the engine rooms was flooded, and one of the shafts was damaged and had to be shut down. The ensuing flooding caused a severe list, but this was quickly corrected to a manageable 6°. The veteran carrier had an experienced and capable damage-control team. By 0850hrs, the fires were extinguished, and 23 knots were restored using the starboard shafts. However, steering was uneven, and the ship’s transmitters were out of commission. Since she was no longer suitable as a flagship, plans were made to transfer Ozawa and his staff to cruiser Oyodo. Before this could happen, the second strike showed up.
Zuiho was caught out of formation launching aircraft when the first attack began. Enterprise’s strike group targeted the veteran light carrier known to her crew as a lucky ship, since she had survived three earlier carrier battles. Reports from Enterprise air crew stated that the carrier was left dead in the water and on fire. In exchange, one Enterprise Avenger was seriously damaged by antiaircraft fire and was rolled over the side of the carrier when it landed back onboard. Another Enterprise Hellcat was lost to Zero attack. Intrepid Helldivers also selected Zuiho for attack and claimed hits. In fact, Zuiho suffered three near misses followed by a direct bomb hit at 0835hrs. The explosion caused fires on the hangar deck, but these were out by 0855hrs. After the dive-bombers did their work, torpedo bombers from Essex and Lexington attacked Zuiho, but no hits were gained.
Light carrier Chitose was crippled early and was the first of Ozawa’s carriers to sink. At 0835hrs, she was attacked by dive-bombers from Essex and Lexington. Helldivers from Essex reported dropping 12 bombs and claimed 8 hits, leaving the carrier burning and listing. In fact, Chitose suffered three near misses along her port side. This was enough to rupture the carrier’s unarmored hull. The resulting flooding knocked out two boiler rooms and caused a severe 27° list. Damage-control efforts reduced the list and kept power, but steering was only accomplished by using the engines. At 0915hrs, progressive flooding knocked out the starboard engine room and speed fell below 14 knots. Ten minutes later, flooding caused all power to be lost and the list increased to a dangerous 30°. Hyuga was directed to tow the carrier, but her condition was beyond salvage. Chitose sank at 0937hrs with the loss of 904 officers and men; another 601 were saved. Light cruiser Tama was attacked by torpedo bombers from Belleau Wood and San Jacinto. One torpedo hit the ship in her boiler room. After emergency repairs, the cruiser was ordered to proceed independently to Okinawa at her best speed of 14 knots.
Oyodo was also subjected to attack and was slightly damaged. At 0848hrs, she was struck by a bomb and two rockets and recorded near misses from bombs. The cruiser’s speed was unimpaired. Large destroyer Akizuki also came under attack from aircraft in the first strike. At 0842hrs the ship was struck amidships and set afire. The ship lost power and fell out of formation. Within minutes, a large explosion was noted amidships and at 0856hrs Akizuki broke in two and quickly sank. The cause was either a torpedo or a bomb hit that detonated torpedoes in the amidships torpedo mount. The commanding officer and 150 officers and men were pulled out of the water before more air attacks forced destroyer Maki to abandon rescue operations. Meanwhile, as this attack unfolded, Mitscher launched a second strike of 36 aircraft, which reached the target area around 09:45. Coordinated by McCampbell, these planes focused on the carrier Chiyoda, which was hit by one bomb and several near misses, resulting in flooding and a severe list, ultimately bringing the carrier to a halt.
The climax of Halsey’s battle of annihilation against the Main Body should have been an engagement by Task Force 34 with six of the world’s most powerful battleships. But this was never to be. The plight of the escort carriers off Samar brought a flurry of urgent pleas to Halsey for assistance. These began at 07:07 with a plain text message from Kinkaid. In response, Halsey ordered Task Group 38.1 to steam west from Ulithi to support Kinkaid, but otherwise remained focused on crushing Ozawa with the rest of Task Force 38. This changed when Nimitz weighed in at 10:00 with an inquiry on the location of Admiral Lee’s battleships, which finally prompted Halsey to order Task Force 34, supported by Task Group 38.2, south at 10:15. At this point, Task Force 34 was some 42NM away from Ozawa’s remnants. This order was executed at 11:15 when the battleships turned south, yet the change of orders came too late. Even at their best speed, the battle line could not arrive off San Bernardino Strait until about 01:00 on October 26. At 13:45, Task Force 34 also slowed from 20 to 12 knots to fuel destroyers, something that took until 16:22.
By noon, as Ozawa transferred to the Oyodo, Mitscher launched his third strike. Launched between 1145hrs and1200hrs, the third strike was the largest and most effective of the day. It was active over the target area from about 1310hrs to 1400hrs with some 200 aircraft, 75 percent of which had taken part in the initial strike in the morning. The strike coordinator was Commander T. Hugh Winters from Lexington. By this point, the Main Body’s formation was in a shambles. Two carriers were located to the north with a battleship and what was reported as two cruisers. Another carrier was located some 20NM to the south on fire and listing. A second battleship, a cruiser, and a destroyer were nearby the crippled carrier. Winters ordered TG 38.3’s 98 aircraft from Essex, Lexington, and Langley, to go after the two operational carriers. Aircraft from Lexington focused on Zuikaku. By 1100hrs, Ozawa had departed his flagship and transferred to Oyodo. The nine surviving Zeros on CAP were forced to ditch around 1030hrs, so for the rest of the day the Americans faced no air opposition. Zuikaku worked up to 24 knots shortly after the third strike was spotted at 1308hrs. The attack by Helldivers and Avengers was well coordinated, with the Avengers coming in from both bows in an anvil attack. In less than ten minutes, Zuikaku was subjected to six torpedo hits—two on the starboard side and four on the port side. The first was a hit at 1315hrs that failed to detonate. The last of the six hit at 1323hrs. Within minutes of the last torpedo hit, the mighty carrier was listing to port by 14° and was dead in the water after all power was lost. In addition to the torpedoes, four bombs hit the ship, which resulted in renewed fires on the hangar decks. At 1327, with the list increasing to 21°, the crew was ordered up to the flight deck. The captain gave a final address and then the ensign was lowered. Finally, after this touch of the dramatic, the crew was ordered to abandon ship at 1358hrs. The ship rolled over at 1414hrs and took the captain, 48 other officers, and 794 enlisted men with her. Essex’s strike focused on Zuiho. When aircraft from TG 38.4 arrived, including Enterprise’s second strike of six Hellcats, ten Helldivers, and five Avengers, most were also directed at Zuiho at 1310hrs followed by more at 1330hrs. At 1317hrs, the carrier was hit by one torpedo on her starboard quarter. According to Japanese accounts, one small bomb hit the aft elevator, followed by seven very close near misses, and then 60 more near misses. Bomb fragments caused flooding in the starboard engine room and created a 13° list.
Mitscher’s fourth strike, launched around 13:15 and reaching the target area by 14:45, involved 40 aircraft but only achieved ten near misses on the Zuiho and four near misses on the battleship Ise. Despite this, the Zuiho ultimately sank at 15:26, with 215 men lost. At 16:10, Mitscher launched his fifth strike, while a strong surface force under Rear-Admiral Laurance DuBose closed in on Chiyoda to finish her off. DuBose’s force first encountered Chiyoda dead in the water with light cruiser Isuzu nearby preparing to rescue survivors. Isuzu quickly fled, leaving the heavy cruisers to open fire at Chiyoda at 1624hrs from some 20,000 yards. The carrier responded with her 5in. dual-purpose guns, but against a stationary target the American cruiser scored quickly and often and after 15 minutes the carrier was a mass of flames. A towering column of black smoke marked Chiyoda’s final moments. At 1655hrs, the carrier rolled over—there were no survivors from her crew of 970 men.
Between 17:10 and 17:40, the fifth strike, consisting of 85 aircraft, targeted the Ise. However, due to pilot fatigue, only one bomb hit the battleship, with 34 near misses causing minor flooding. The sister ship, Hyuga, which was positioned south of the Main Body, experienced seven near misses but no direct hits. Mitscher then launched a final strike of 36 aircraft at 17:10, which reached the target area about an hour later but failed to cause further damage. Overall, Task Force 38 executed 527 sorties against Ozawa’s force that day, marking the most intense effort by fast carriers against naval targets up to that point. Despite the lack of significant air opposition and heavy but largely ineffective anti-aircraft fire, the results were underwhelming. The limited damage can be attributed to heavy anti-aircraft fire, effective ship maneuvering, and pilot fatigue from previous attacks on the Sibuyan Sea. The Battle off Cape Engaño was not over yet. As DuBose’s mop-up force continued north, they encountered three destroyers rescuing survivors from Zuikaku and Zuiho. At 18:52, DuBose’s light cruisers engaged the Hatsuzuki, which tried to resist but was ultimately destroyed by the intense gunfire, sinking at 20:59. DuBose ceased his pursuit at 21:30. This decision was timely, as Hatsuzuki’s distress calls led Ozawa to advance south with three battleships and one destroyer at 20:41. Finding no targets, Ozawa turned back at 23:30, bringing the battle to an end.
On his retreat, two wolf packs were lying in wait. Although Ise avoided significant damage from a powerful torpedo attack at 18:44, the Tama, already damaged, wasn't as fortunate. The cruiser was proceeding independently to Okinawa at 14 knots after taking a torpedo in the first air attack. Jallao’s skipper fired three torpedoes from her bow tubes, but they all missed. He quickly lined up another shot with the four stern tubes. Three of the four hit, and two exploded. The damage was catastrophic, causing Tama to break in two and quickly sink. There were no survivors from the crew of some 450 men.
Meanwhile, Halsey had dispatched the fastest ships from his battle line at 16:22 in a last-ditch effort to intercept Kurita’s force before it could navigate the San Bernardino Strait. However, they arrived too late, as aircraft from Independence detected Kurita’s force moving through the strait at 21:40. The only ship that did not make it was the destroyer Nowaki, which, overloaded with survivors from Chikuma, was attacked by the American forces at 00:54 on October 26 and was swiftly sunk by 01:32. During this time, General Krueger’s offensive persisted with General Sibert’s 10th Corps and General Hodge’s 24th Corps making steady progress inland. To the north, cavalry units secured San Juanico Strait, while Colonel Newman’s 3rd Battalion captured Hill C and Colonel Chapman’s 2nd Battalion took Hill B despite heavy resistance. Additionally, Chapman’s 1st Battalion secured Hill 85, and the majority of the 3rd Battalion advanced towards Castilla, 8000 yards southwest of Palo. Further south, a patrol from the 383rd Regiment reached the Binahaan River and linked up with Chapman’s Company K; the 382nd Regiment pushed beyond Aslom and Kanmonhag; Colonel May’s Company K attempted, but failed, to capture Tabontabon; the 17th and 184th Regiments consolidated their newly captured positions on Burauen while sending patrols towards Dagami; and the 32nd Regiment made some headway toward the Buri airstrip but was still unable to capture it.
By October 26, Shima’s two heavy cruisers and two destroyers had successfully evaded several PT boat attacks and made their escape. However, the damaged cruiser Abukuma, under the protection of destroyer Ushio, was struck by 43 B-24 heavy bombers in the Sulu Sea. Usually high-altitude attacks on ships were totally ineffective, so the bombers came in at an altitude of about 6,500ft. In the first attack, Abukuma took a direct hit in the area of her bridge at 1006hrs and another aft. The second group of bombers scored a damaging near miss forward, and then a direct hit aft that knocked out one of the shafts and the steering equipment. The resulting fires spread to the engine rooms and the torpedo mounts located aft. When the fires reached the torpedoes, four exploded at 1037hrs. A third attack at 1044hrs brought only near misses. Abukuma was mortally damaged but remained afloat long enough for 284 of the crew to leave the ship. The veteran cruiser, part of the force that attacked Pearl Harbor, sank at 1242hrs with the loss of 220 men (added to the loss of 37 from the torpedo hit from the PT boat). As they came in at a lower altitude, Abukuma and Ushio were able to account for three bombers in this action.
On the same day, kamikaze attacks resumed against Taffy 1. Three Zeros penetrated the CAP and attacked Suwannee, which had completed repairs from the prior day’s suicide attack. One Zero hit the flight deck and smashed into a group of ten aircraft parked on the bow. The aircraft were quickly engulfed in flames that spread down into the hangar bay, where another ten fueled aircraft were preparing to be brought up to the flight deck. The resulting fires on the hangar deck were put out, followed two hours later by the fire on the flight deck. The crew paid a high price for saving their ship— 85 dead, 58 missing, and 102 wounded. Other kamikazes selected Sangamon and Petrof Bay for attack; both carriers reported being near-missed.
The initial success of the kamikaze attacks, including one carrier sunk and five damaged, gave the Japanese hope that they had found a way to halt the American naval advance. This marked the beginning of the Kamikaze era in the Pacific War. As Kurita’s force moved through the Sibuyan Sea, Admirals McCain and Bogan launched a strike at 06:00 with 257 aircraft. Despite this effort, the exhausted pilots managed only three bomb hits on Kumano, causing moderate damage. Aircraft from Wasp and Cowpens also found Kurita’s main force. Noshiro was able to evade six torpedoes aimed at her, but at 0852hrs one struck with devastating effect. The ship lost all power and within minutes developed a 26° list to port. The next attack was conducted by aircraft from Hornet. A second torpedo hit the lightly protected cruiser at 1039hrs, and at 1113hrs she sank bow first. By this point, Kurita’s destroyers were down to their last few tons of fuel, forcing them to reduce speed. Destroyers had to shift fuel among themselves to reach a tanker positioned at Coron Bay. Hayashimo was forced to temporarily anchor off Semirara Island south of Mindoro. She was attacked by Avengers from 1045hrs to 1050hrs, and had her bow blown off by a torpedo. As a result, she was grounded and sank in shallow water off Semirara Island. Kurita’s remaining ships managed to reach Coron Bay or Brunei, except for the destroyers Fujinami and Shiranui, which were sunk by air attacks on October 27, resulting in the loss of their crews, including those from Chokai aboard Fujinami. By the end of the Battle of Leyte Gulf, the IJN had been effectively decimated.
Despite suffering a severe defeat, Admiral Mikawa assessed that he still had enough resources to carry out Operation TA, which involved transporting reinforcements to Ormoc. On October 24, the cruiser Kinu and the destroyer Uranami escorted five transports through intense strafing fire to Cagayan. After boarding the 41st Regiment, Admiral Sakonju’s convoy set sail the next morning and successfully landed the reinforcements at Ormoc early on October 26. Although they faced occasional enemy air attacks, they did not incur significant troop losses. Sakonju then sent three transports to Manila, but these were targeted by aircraft from Sprague’s carriers. The attacks resulted in two bomb hits on Uranami and three on Kinu, leading to the sinking of both ships in the Visayan Sea. Another transport proceeded to Bohol, embarked the 169th Independent Battalion, and landed them at Ormoc on October 27. Although the Leyte beachheads were secured against sea-based attacks, the Americans could not control all surrounding waters, allowing Generals Yamashita and Suzuki to continue reinforcing the island. This marks the conclusion of the Battle of Leyte Gulf. In exchange for the loss of one light carrier, two escort carriers, two destroyers, one destroyer escort, one submarine, one PT boat, 255 aircraft, and about 2,000 men, the Americans had destroyed approximately 300 enemy planes and sunk 28 warships, including the carrier Zuikaku (the last survivor of the Pearl Harbor attack), three light carriers, three battleships, ten cruisers, and eleven destroyers, with a total of 12,000 Japanese casualties.
Despite losing all his carriers, Ozawa fulfilled his expected role and managed to survive the battle with two battleships and two cruisers. After the war, he noted that the final three strikes were not damaging, and his chief of staff remarked that he was unimpressed with the American pilots' quality. In contrast, Halsey faced severe criticism for his controversial decision to leave San Bernardino Strait unguarded while moving his entire force north. If he had employed more strategic thinking and embraced decentralized decision-making, Mitscher’s carriers could have engaged and defeated both Ozawa and Kurita. Nishimura also performed his duties effectively; despite losing his life and almost his entire force, he diverted the 7th Fleet’s surface forces, leaving Kinkaid’s transports and escort carriers vulnerable to Kurita’s attack. The Shima force contributed nothing to the mission but survived largely intact. Kurita demonstrated bravery throughout the battle but was occasionally indecisive. Although he was not responsible for the losses at the Sibuyan Sea and was unlucky with his lookouts misidentifying cruisers and battleships among Sprague’s escort carriers, he faced American tactics that he perceived as skillful. Sprague’s desperate maneuvers to avoid annihilation were seen by the Japanese as tactical excellence. Kurita acknowledged the effective performance of American destroyers, which broke up his formation with torpedo attacks and utilized smoke screens effectively. Both Kurita and his chief of staff found the American air attacks to be relentless, aggressive, skillful, and well-coordinated, considering them the most proficient attacks encountered by the 1st Striking Force throughout the battle.
In the end, Toyoda’s Sho-Go plan was fundamentally flawed and destined for failure. Although it contained some clever elements that exploited weaknesses in the US Navy’s command structure, it was ultimately incapable of success and served only as a means of the IJN’s destruction. Even if Kurita had advanced into Leyte Gulf, it would have provided no significant military advantage for the Japanese and would likely have led to the complete destruction of Kurita’s forces. The failure of Sho-Go left the Japanese without a fleet and with no realistic hope of defeating the Americans. However, the emergence of Kamikaze attacks allowed Japan to continue the war for a while longer.

The Imperial Japanese Navy was virtually annihilated during the battle of Leyte Gulf. Few of her mighty warships remained and now she would cling to desperate measures to try and force the Americans to sue for an early peace to retain pieces of her empire. How long could Japan drag this war on?

22 10月· The Pacific War - week by week
Last time we spoke about the Return to the Philippines. Admiral Halsey, in preparation for the Leyte invasion, devised a strategic ploy to lure the Japanese forces by feigning vulnerability. Despite significant air engagements and the heavy damage to two cruisers, Halsey’s forces maintained control. Meanwhile, a massive convoy approached Leyte, and the Japanese launched a desperate counterattack. The battle severely depleted Japan’s air strength, leading to the birth of the Kamikaze Corps. As Davison's carrier aircraft attacked, Japanese forces struggled due to bad weather and underestimated the Americans. General Terauchi activated Sho-Go 1, targeting Leyte, despite disagreements with General Yamashita. Pre-landing operations saw U.S. Rangers secure islands, while heavy bombardments prepared Leyte for invasion. MacArthur’s forces landed amidst fierce resistance, capturing key positions. Though logistics were disorganized, U.S. troops gained ground, marking the beginning of a decisive battle in the Philippines, with the Japanese struggling to counter.

As previously mentioned, General MacArthur’s forces successfully landed on Leyte, with General Sibert’s 10th Corps landing in the Palo-Tacloban sector and General Hodge’s 24th Corps at Dulag. In response, Admiral Toyoda activated Operation Sho-Go, ordering Admiral Kurita’s 1st Striking Force to move to Brunei Bay and destroy enemy warships and transports in Leyte Gulf. Meanwhile, Admiral Shima’s 2nd Striking Force prepared to support counter-landings led by Vice-Admiral Mikawa Gunichi’s Southwest Area Fleet. The planning for Admiral Shima’s small force was emblematic of the shambolic state of the IJN organization for the battle. His force was originally assigned to Ozawa as part of the Main Body. Then it was detached to go down to Formosa to mop-up Halsey’s Third Fleet in the aftermath of the Battle off Formosa. Then it was assigned to the Southwest Area Fleet based in Manila to spearhead an envisioned counter-landing on Leyte. The commander of the Southwest Area Fleet, Admiral Mikawa, determined that the Shima force was not required to accomplish the counter-landing mission. On October 19 Toyoda rejected this and instructed Mikawa to use the Shima force as part of the counter-landing force. In spite of this and after confirming that the counter-landing operation did not require Shima’s force, Mikawa sent orders to Shima on the afternoon of the 19th that he was not required to stand by to support the counter-landing. Early in the afternoon on October 21, the Combined Fleet again ordered Shima to take part in the transport mission and ordered his force to Manila. At this point, two forces were assigned to the counter-landing operation with a total of five cruisers and eight destroyers. This was a very questionable use of the Combined Fleet’s limited resources.
Kurita’s 16th Cruiser Division was detached to reinforce the effort, and Admiral Ozawa’s depleted Main Body was tasked with luring the enemy north, allowing Kurita to break through to the landing zone. Vice Adm. Ozawa's Task Force Main Body sortied from the Bungo Channel, at the southern entrance to the Inland Sea, on the afternoon of October 20, immediately after receiving the Combined Fleet battle order. To heighten its effectiveness as a lure, the Ozawa Force sortied with all of the 3d Carrier Division, made up of the regular carrier Zuikaku and the light carriers Zuiho, Chitose, and Chiyoda. The total number of aircraft available to put aboard these ships, however, was only 108. These belonged to the poorly trained air groups of the 1st Carrier Division and represented about half the normal complement. In addition to the half-empty carriers, the force comprised two battleships (Ise, Hyuga), three light cruisers(Oyodo, Tama, Isuzu) and eight destroyers (31st Destroyer Squadron). At around 06:00 on 21 October, Japanese aircraft attempted to bomb the Allied ships in Leyte Bay. An Aichi D3A dive-bomber dove for Shropshire, but broke away after heavy anti-aircraft fire was directed at it. The Aichi, damaged by Bofors fire, turned and flew at low level up the port side of the nearby Australia, before striking the cruiser's foremast with its wingroot. Although the bulk of the aircraft fell overboard, the bridge and forward superstructure were showered with debris and burning fuel. Seven officers (including Captain Dechaineux) and twenty-three sailors were killed by the collision, while another nine officers (including Commodore Collins), fifty-two sailors, and an AIF gunner were wounded. Observers aboard Australia and nearby Allied ships differed in their opinions of the collision; some thought that it was an accident, while the majority considered it to be a deliberate ramming aimed at the bridge. Following the attack, commander Harley C. Wright assumed temporary control of the ship. Since Kurita lacked air cover, Tominaga’s forces were regrouping in the Philippines to bolster Japanese air strength for Operation Sho-Go, while Admiral Fukudome’s 2nd Air Fleet was assembling in the Manila area.
At the same time, with communication lost with General Makino’s 16th Division.Because of the typhoon of October 17-18, signal communications were impossible. Roads were washed out and impassable. Bridges were down; and for about a week from the time the storm first hit the island, elements of the 16th Division were scattered and out of contact with one another. While trying to assemble its forces for operations, the Japanese were then hit by enemy bombardment, which further severely disrupted General Makino’s radio-telegraphic communications. Additionally, the evacuation of Tacloban by the division rear echelon, which began early on October 20, necessitated the abandonment of permanent wireless installations and resulted in complete severance for 48 hours of all contact between the 16th Division and higher headquarters at Cebu and Manila. During this critical period, 14th Area Army and 35th Army were completely without knowledge of developments on Leyte.
General Suzuki initiated the Suzu Plan, preparing the 41st Regiment and two battalions of the 102nd Division to move toward Ormoc. General Terauchi, having decided that the decisive battle would be fought at Leyte, directed General Yamashita to place the provisional Tempei Battalion and the 20th Antitank Battalion under Suzuki’s command and ordered Lieutenant-General Yamagata Tsuyuo’s 26th Division to prepare for early deployment to Leyte. Additionally, reinforcements from the 1st Division and the 68th Brigade, soon to arrive in the Philippines, were assigned to the 35th Army. The Japanese anticipated that the enemy would not move inland until the beachheads at Tacloban and Dulag were connected, so they aimed to gather reinforcements in the Carigara area before launching a major counteroffensive to crush the invading forces. In the meantime, Makino’s 16th Division was tasked with holding off the enemy advance in eastern Leyte long enough to allow reinforcements to assemble. Reacting swiftly to the enemy landings, Makino sent the reserve 1st Battalion, 20th Regiment, and the 7th Independent Tank Company to strengthen the defenses at Palo and Dulag, respectively.
General Krueger, however, intended to move quickly through Leyte Valley, aiming to secure key roads and airfields before the Japanese could regroup and mount a solid defense. The 1st Striking Force departed Lingga at 01:00 on October 18 and headed to Brunei Bay on the north coast of Borneo. At Brunei, Kurita’s ships refuelled, and Kurita took the opportunity to confer with his officers. The details of Sho-1 reached Kurita’s force during the day on October 18. This made for a dramatic conference and reflected the unease many felt about the plan. Many officers at the conference were appalled that the fleet was being risked attacking empty transports and doubted that they would ever get close to Leyte Gulf. Kurita probably had his own doubts about the plan, but after many of those present expressed their doubts, Kurita reminded them of the “glorious opportunity” they had been given. “Would it not be a shame to have the fleet remain intact while the nation perishes?” posed Kurita, and followed with the plea: “What man can say that there is no chance for our fleet to turn the tide of war in a decisive battle?” Whatever their doubts, the crews and ships of the 1st Striking Force departed Brunei at 08:00 on October 22 and headed northeast through the Palawan Passage. Kurita’s 3rd Section—consisting of the old battleships Fuso and Yamashiro, heavy cruiser Mogami, and four destroyers—stayed behind. These ships departed at 15:00 and headed to the Balabac Strait and then into the Sulu Sea. If all went according to plan, they would storm Leyte Gulf through the Surigao Strait and meet Kurita’s ships inside the gulf on the morning of October 25.
To the north, General Mudge’s 1st Cavalry Division continued advancing northwest along San Juanico Strait, with the 7th Cavalry liberating Tacloban with minimal resistance. The 5th and 12th Cavalry Regiments faced tougher opposition in the southwestern foothills, where Colonel Royce Drake was killed by enemy machine-gun fire, but they managed to secure Utap and Caibaan despite the swampy terrain. To the south, Colonel Aubrey Newman’s 34th Regiment repelled a strong enemy counterattack, resulting in 600 Japanese casualties, before launching an assault on Hill 332. Although only the northern knoll was captured by nightfall, the 1st Battalion, 19th Regiment consolidated its position on Hill 522, while the 2nd and 3rd Battalions advanced towards Palo, with the 2nd successfully entering the town.
Further south, Japanese artillery positioned on Catmon Hill targeted the beachhead area while General Bradley's 96th Division advanced. Colonel May’s 1st Battalion attacked the Japanese positions at Labiranan Head, the remaining forces of the 383rd Regiment moved west to a point north of Tigbao, and Colonel Dill’s 382nd Regiment made slow progress towards Tigbao. At the same time, General Arnold’s 7th Division, after repelling two minor tank attacks, began advancing west toward the Burauen airstrips, with the 32nd and 184th Regiments moving side by side. The 184th faced minimal opposition as it captured the Dulag airstrip and continued moving forward about 1000 yards beyond the beachhead, whereas the 32nd had to overcome several bunkers and pillboxes to reach its objective. The next day, both regiments continued their westward advance, with the 184th stopping after 2800 yards due to increased enemy resistance, waiting for the 32nd to close the gap. To the north, May’s 1st Battalion secured Labiranan Hill and San Roque, while the rest of the 383rd Regiment advanced to Anibung to surround Catmon Hill, and the 382nd Regiment pushed through Tigbao and Canmangui. In response to these developments, Makino decided to reorganize his southern forces to better defend Catmon Hill and Burauen, with the 20th Regiment largely disengaging and retreating towards Hindang. Simultaneously, the 34th Regiment captured Hill 332, while Lieutenant-Colonel George Chapman’s 19th Regiment defended Palo from strong enemy counterattacks. The 3rd Battalion managed to reach the town, allowing the 2nd Battalion to launch an attack towards Hill B, though it was unable to capture its crest. Further north, while the 7th Cavalry secured the hills around Tacloban, Brigadier-General William Chase’s 1st Cavalry Brigade continued to face challenges advancing up the western foothills.
In the morning, Kurita set sail from Brunei and headed northeast through the Palawan Passage, leaving Vice-Admiral Nishimura Shoji’s Force C behind to advance through the Surigao Strait into Leyte Gulf. Taking the direct route along the west coast of Palawan, the 1st Striking Force was detected by submarines Darter and Dace in the early hours of October 23. After reporting the enemy task force to Admirals Halsey and Kinkaid, the submarines executed a coordinated attack at 06:10. The first torpedoes struck Atago just as Kurita was having morning tea with his chief of staff. In total, four torpedoes hit the cruiser, dooming her instantly. Nineteen officers and 341 sailors went down with the ship. Kurita and his staff were thrown into the water and had to swim for their lives. The second salvo from Darter hit cruiser Takao, steaming behind Atago. Two torpedoes hit the cruiser, killing 32 crewmen and wounding another 30. Takao was not only out of the battle, but her heavy damage put her out of the war. After eventually reaching Singapore, she was deemed unrepairable.On Dace, Claggett observed Darter’s devastating attack. Claggett identified a Kongo-class battleship for attack and began his approach. Six torpedoes were fired from a range of 1,800 yards toward the target, which was actually heavy cruiser Maya. The cruiser took four hits on her port side and sank in a mere eight minutes, taking with her 16 officers and 320 men.
Kurita narrowly escaped the sinking of the Atago, later transferring to the battleship Yamato after sending two destroyers to escort the damaged Takao back to Brunei. The submarines then endured ineffective counterattacks from Japanese destroyers, although Darter ran aground on a reef while pursuing Takao. This successful submarine attack not only diminished Kurita’s force by three powerful cruisers but also provided the Americans with the location of the 1st Striking Force. In response, Admiral Oldendorf’s fire support group established a battle line across the mouth of Surigao Strait, and Halsey ordered his dispersed carrier groups to prepare for battle, recalling Task Group 38.4 immediately. Additionally, Vice-Admiral Sakonju Naomasa’s 16th Cruiser Division, en route to Mindanao with the 41st Regiment for Ormoc, was tracked by submarine Bream near Manila Bay early on October 23. This led to a torpedo attack that critically damaged the heavy cruiser Aoba, forcing her to return to Japan, where she would never be operational again. Despite these challenges, the first reinforcement successfully arrived in Ormoc on the same day after an uneventful voyage.
At the same time, the IJA and IJN air forces were rapidly assembling their resources in the Philippines in preparation for a coordinated air offensive set to begin on October 24, a day before the scheduled fleet attack. To the north, Ozawa's substantial but ineffective decoy force was positioned due east of Okinawa, moving south into the Philippine Sea, while Shima’s 2nd Striking Force neared the Coron Islands. Back in Leyte, Krueger’s offensive was advancing as well. In the north, the 8th Cavalry had moved through the 7th and successfully captured a bridge over the Diit River. On October 22, elements of the 5th Cavalry were sent to Tacloban to act as a guard of honor for General MacArthur. The guard of honor, consisting of 1st Lt. John Gregory and thirty enlisted men of the 5th Cavalry, arrived at Tacloban later on October 23. President Osmeña of the Philippine Commonwealth was also present, having come ashore for the occasion. A simple but impressive ceremony was held in front of the municipal building of Tacloban, though the interior of the edifice was a shambles of broken furniture and scattered papers. A guard of honor of "dirty and tired but efficient-looking soldiers" was drawn up in front of the government building. General MacArthur broadcasted an address announcing the establishment of the Philippine Civil Government with President Osmeña as its head. Lt. Gen. Richard K. Sutherland then read the official proclamation. President Osmeña spoke appreciatively of American support and of the determination of the Filipinos to expel the enemy. "To the Color" was sounded on the bugle, and the national flags of the United States and the Philippines were simultaneously hoisted on the sides of the building. Colonel Kangleon of the guerrilla forces was then decorated with the Distinguished Service Cross. Few Filipinos except representatives of the local government were present for the ceremony. Apparently the inhabitants had not heard of it, or did not know that they were permitted to attend. Information quickly spread, however, that the civil government had assumed control, and as General MacArthur and his party left town the civil population cheered them.
The 1st Cavalry Brigade continued its slow advance through challenging terrain before being reassigned to support the overstretched 24th Division in its rear. Newman’s 1st Battalion made an unsuccessful attempt to capture Hill Nan, and the 19th Regiment similarly failed to take Hill B. On the night of October 23 Col. Suzuki Tatsunosuke, the commanding officer of the 33rd Regiment, led a raiding detachment, armed with rifles, sabres, grenades, and mines, into Palo from the southwest. Using Filipino civilians in front of them, the men of the detachment tricked the guards at the outpost into believing that they were guerrillas. The Japanese were thus able to capture two machine guns and a 37-mm. gun. They penetrated to the town square and charged, throwing explosives into houses, trucks, and a tank, and broke into an evacuation hospital where they killed some wounded. They then moved toward the bridge and mounted the captured machine guns on it, firing until their ammunition was exhausted and then abandoning the guns. The American guards on the other side of the bridge, however, were able to fire upon the bridge and its approaches so effectively that they killed fifty Japanese, according to a count made the next morning. The raid was completely broken up, and sixty Japanese, including Colonel Suzuki, were killed. The American casualties were fourteen killed and twenty wounded.
To the south, the 383rd Regiment secured the Guinarona River, while the 382nd conducted patrols. Even farther south, Arnold deployed the 17th Regiment, reinforced by the 2nd Battalion of the 184th Regiment and the 767th Tank Battalion, to push through his advance elements and continue the assault westward, with the other two regiments trailing 1000 yards behind. This "flying wedge" maneuver proved highly effective, with the infantry securing San Pablo airfield and the tanks advancing to the western edge of Burauen. They disrupted the disorganized enemy forces and killed Colonel Hokota Keijiro, commander of the 20th Regiment.
Meanwhile, at sea, Kurita's intact warships advanced into Mindoro Strait by nightfall, while Nishimura's force was crossing the Sulu Sea. To the north, Ozawa's decoy force was deliberately broadcasting messages to draw enemy attention. Shima was also directed to penetrate Surigao Strait to support Nishimura’s assault, as Mikawa had determined that the 2nd Striking Force was not needed for the counter-landing mission. On Leyte, the troops continued their engagement on October 24, unaware of the impending major naval battle. In the northern region, to secure San Juanico Strait and prevent Japanese reinforcements from Samar, the 1st Squadron, 7th Cavalry landed successfully at Babatngon; Troop C of the 8th Cavalry did the same at La Paz; and the rest of the 1st Squadron advanced to Guintiguian. By nightfall, these cavalry units had to repel a strong counterattack from the 2nd Battalion, 9th Regiment, which was stationed in Samar. To the south, Newman’s 1st Battalion secured Hills Nan and Mike; his 2nd Battalion fought its way to a small hill southeast of Hill C; Chapman’s 2nd Battalion continued its unsuccessful assault on Hill B; and his Company K captured San Joaquin south of Palo. Further south, the 382nd Regiment pushed through Hindang, causing the 20th Regiment units to retreat, and also secured Anibung, while the 383rd Regiment began patrolling its area. Meanwhile, the 17th Regiment, supported by the 184th, advanced along the road to Burauen, fought through the town, and began preparing for a push north to Dagami. Additionally, the 32nd Regiment attacked toward the Buri airstrip but was eventually forced to withdraw.
At dawn on October 24, the crucial air phase of the Sho-Go plan began, with 200 aircraft of the 1st and 2nd Air Fleets taking off from Clark Field to patrol the waters east of Luzon. At 08:20, Admiral Sherman’s carriers were finally spotted, prompting the launch of three waves of Japanese aircraft for an attack. The first attack in the morning was intercepted by seven Hellcats from Essex led by Commander David McCampbell, the air group commander. The quality of the Japanese air crews was very low. McCampbell methodically proceeded to shoot down nine Japanese aircraft, for which he was awarded the Congressional Medal of Honor, and his wingman claimed six more. After the record action, he managed to return and land in extremis on Langley because the Essex's deck was too busy to accommodate him although he had run short of fuel. Altogether, aviators from Essex were credited with 24 downed enemy aircraft, and fighters from Lexington 13. Despite the Hellcats’ rough handling of the incoming Japanese strike, fleet air defense was never airtight. At 0938hrs, one Judy divebomber used clouds for cover and then made a skillful attack against light carrier Princeton. The aircraft’s 551lb bomb hit in the middle of the flight deck some 75ft forward of the aft elevator. It penetrated several decks to the ship’s bakery, where it exploded. The resulting blast reached into the hangar deck where it engulfed six fully armed and fully fueled Avengers. These aircraft caught fire and soon exploded with a blast so powerful both ship’s elevators were thrown into the air. Water pressure was knocked out, which allowed the flames to spread quickly. All non-essential personnel were ordered off the ship at 1010hrs, followed by all but the fire-fighting personnel ten minutes later. In response, the cruiser Birmingham came to Princeton’s aid but sustained severe damage from a major explosion and had to retreat to Ulithi, leading to Princeton being scuttled later in the afternoon. The subsequent two waves of Japanese aircraft were successfully intercepted, resulting in the loss of 67 Japanese planes by the end of the day. Meanwhile, Tominaga launched full-scale attacks on enemy invasion shipping in Leyte Gulf with minimal results. The failure to neutralize Halsey’s carriers and Ozawa’s undetected diversion mission allowed Admiral Mitscher to conduct a series of strikes against Kurita’s force. That morning, American reconnaissance aircraft detected Kurita’s 1st Striking Force south of Mindoro, prompting Admiral Bogan to dispatch 45 aircraft under Commander William Ellis to attack the battleships Yamato and Musashi as they neared the Sibuyan Sea.
At approximately 10:30, aircraft from the Intrepid and Cabot began their attack. The lead group of Japanese ships included the huge Yamato and Musashi. Of these two, Musashi was nearest, so Commander Ellis selected her as the main target. He split the 12 Helldivers into two six-aircraft divisions to attack both battleships with their 1000lb bombs. The two nearest large ships were the subject of the Avengers’ attack. Two were ordered to go after heavy cruiser Myoko and the other six were directed against Musashi. These were divided into two three-plane sections in order to execute an anvil attack. The four Avengers from Cabot were allocated against Yamato in the center of the formation. American pilots all remarked on the ferocity of the antiaircraft fire from the multi-colored 5in. bursts to the streams of tracers from the 25mm guns. The Japanese also used Type 3 incendiary shells from 18.1in. and 16in. main battery guns. Despite the spectacular appearances of this barrage, Japanese anti-aircraft fire was generally ineffective. The giant Type 3 shells proved totally ineffective, and Japanese records indicate that the battleships fired a relatively low number of 6in. and 5in. shells during each attack, indicating that the fire-control systems were taking too long to generate a targeting solution. These and the ubiquitous 25mm guns damaged many aircraft, but of the over 250 aircraft that attacked during the day, only 18 were shot down. Though the numbers confirm the ineffectiveness of IJN anti-aircraft fire, the American aviators displayed great courage pressing home their attacks through what was described as an impenetrable wall of flak.
Musashi was hit with one torpedo, leading to flooding and listing, and another torpedo struck the cruiser Myoko, which had to return to Singapore. For most of the day, Musashi was the center of attention. Due to a fault in the design of her side belt, slow flooding entered the adjacent boiler room. The effect of some 3,000 tons of water was a 5.5° list, which was quickly reduced to a single degree by pumps in the affected boiler room and counterflooding on the opposite. Facing Musashi’s intact antiaircraft batteries, one Avenger was shot down before it launched its torpedo and a second went down after deploying its weapon. The two Avengers that attacked Myoko were even more successful. At 1029hrs, one torpedo hit the heavy cruiser on her starboard side aft. Her propulsion system was damaged, and her top speed reduced to 15 knots. The cruiser fell astern of the formation. Kurita was forced to send her back to Singapore for repairs without destroyer escort. Since Myoko was the flagship of Sentai 5, at 1100hrs the commander transferred to cruiser Haguro. Myoko limped back to Singapore but was out of the war. Four of Kurita’s heavy cruisers were out of the battle before they had a chance to engage an enemy ship. Cabot’s small group of torpedo aircraft attacked Yamato, but the battleship dodged all torpedoes directed at her.
Concurrently, Nishimura's fleet was located by an enhanced search operation from Admiral Davison’s carriers. At 09:18, 16 Hellcats and 12 Avengers from the Enterprise attacked the Yamashiro and Fuso battleships, hitting the latter with two bombs, though the damage was minimal. Operating to the west of Nishimura was Shima’s Second Striking Force and also in the area was Shima’s detached Destroyer Division 21 with three ships, which was hurrying to rejoin Shima’s main force after having completed a transport mission to Manila. Franklin’s air group was assigned the northern sector of the Sulu Sea. It spotted the three ships of Shima’s Destroyer Division 21 off Panay. Attacking high-speed destroyers was a challenge for any airman, but at 0813hrs Wakaba was hit by a bomb and several near misses. The damage proved fatal—45 minutes later, Wakaba sank with the loss of 30 men. Franklin launched a follow-up strike of 12 Hellcats and 11 bombers that reached the two remaining destroyers just before noon. Only one bomb hit was scored against Hatsushimo, which did little damage. The Japanese commander decided to head back to Manila with the survivors of Wakaba. Inexplicably, he failed to notify Shima of his decision. Destroyer Division 21 was out of the battle.
After this initial strike, Bogan sent a second wave of 42 aircraft, which targeted Musashi between 12:07 and 12:15. Again, Helldivers opened the attack. The 12 bombers scored at least two direct hits and five near misses. One 1,000lb hit forward and passed through Musashi’s bow without exploding. The second hit just to the port side of the stack and penetrated two decks before exploding. The resulting damage forced the abandonment of the port-side inboard engine room, which reduced the ship to three shafts. A fire near one of the boiler rooms was quickly extinguished. Adding to the chaos, Musashi’s steam siren was damaged, and it continued to sound off and on for the remainder of the action. Once again Intrepid’s Avengers deployed to conduct an anvil attack. Of the nine aircraft, eight got their torpedoes in the water and headed toward the huge battleship. As was the case for the entire series of attacks, it is impossible to precisely trace the number of hits suffered by Musashi; American and Japanese records do not even coincide on the overall number of attacks during the day. It is probable that the second wave of Avengers put three torpedoes into Musashi’s port side. One hit near the stack on the junction of the outboard port engine room and the port hydraulic machinery space; it caused slow flooding but little else. Another hit forward of the armored citadel and caused massive flooding into several large spaces. The last confirmed hit occurred abaft Turret No. 2. Despite these three additional hits, Musashi remained on an even keel, but was noticeably down by the bow. In exchange, Musashi antiaircraft gunners forced one Avenger to ditch some 15 miles away and shot down two Helldivers. During this attack, Japanese records indicate nine Type 3 shells were fired. American pilots were impressed that they were engaged at 25,000–30,000 yards, but no aircraft were damaged.
This damage reduced Musashi’s speed to 22 knots, prompting Kurita to slow his formation. Despite taking four torpedoes, Musashi’s skilled damage-control teams managed to keep it afloat throughout the day. At 10:50, Sherman launched 58 aircraft from the Essex and Lexington, focusing on Musashi again at 13:30. With her speed reduced and unable to fully maneuver, she was a much easier target. Despite the heavy fire directed against them, the Helldivers performed their mission of preparing the way for the torpedo bombers. At least four 1,000lb bombs hit Musashi. Three hits caused minimal damage as they impacted near the forward 18in. turret and exploded in the unoccupied crew accommodation spaces below. Damage from the final hit that exploded on contact when it hit the starboard side of the stack was not serious, but the explosion devastated many nearby 25mm triple mounts and caused heavy casualties among the gun crews. While the Helldivers added to the topside carnage, damage from the Avengers was much more serious. Three more torpedo hits were confirmed in the third attack, bringing the total to seven. Two struck forward of the armored citadel on either side of the bow. The design flaw of having comparatively little compartmentation in the unarmored forward section of the ship led to massive flooding. In addition, the explosions forced the hull plating outward creating what looked like a huge plow throwing water up as the ship moved forward. Another torpedo struck the starboard side close to the previous starboard side hit. This increased flooding and forced the abandonment of the starboard hydraulic machinery room. A possible fourth hit was reported by some witnesses near the forward 6.1in. triple turret on the starboard side.
This assault resulted in at least four bomb hits and three torpedo hits, causing severe flooding. Despite this, Musashi continued to fight, but with its speed reduced to 12 knots, Kurita ordered it to move west with destroyers Shimakaze and Kiyoshimo. Additionally, the cruiser Tone was struck by two bombs during this attack, sustaining only light damage.
At 14:26, 12 Helldivers and 8 Hellcats from the Essex launched an assault on the Yamato and Nagato, delivering three bomb hits to the Yamato and two to the Nagato, though the damage was not severe. The fifth air attack of the day was the most intense, with 65 aircraft from the Enterprise and Franklin taking off at 13:15 to strike the heavily damaged Musashi at 15:10. The results against the near-defenseless battleship were devastating. Of the 18 Helldivers that dove on Musashi, 11 claimed hits. On this occasion, the aviators’ claims were not inflated. Japanese sources agreed that within minutes, Musashi was pounded by ten 1,000lb bombs. This barrage can be detailed with some degree of certainty. One bomb hit forward of Turret No. 1 and added to the damage there from earlier bombs. Another bomb hit the roof of the same turret and failed to penetrate its thick roof armor. Another hit to the starboard side of the turret and penetrated two decks before exploding against the main armored deck. Two bombs hit together between the forward 6.1in. turret and the superstructure, exploded on contact, and did minimal damage. Another two hit just to port in the same general area, penetrated two decks, and exploded on the main armored deck without penetrating. The eighth bomb hit the port side of the massive superstructure and exploded on contact, causing devastation to nearby 25mm mounts and their crews. Another projectile hit the top of the superstructure and destroyed the main battery fire-control director and its rangefinder. The resulting explosion caused significant personnel casualties on the bridge and operations room totaling 78 killed and wounded. Among the wounded was the ship’s captain. The final hit landed abaft the superstructure but caused only minor damage. Musashi was equally helpless against the Avengers. The eight Enterprise Avengers conducted an anvil attack, and all claimed hits. At this point in the action, the accounts of Musashi’s surviving crewmembers are not reliable. It is certain that four more torpedoes hit the ship. The first was on the port side in the area of the magazine for Turret No. 1. Another hit on the port side was recorded abeam the superstructure, flooding one boiler room. The third hit to port was placed just aft of the stack. It was in the same area of an earlier hit, and it immediately flooded the outboard engine room. The only confirmed hit on the starboard side occurred in the area of Turret No. 2. On top of the four confirmed hits, some Japanese accounts mention as many as six more. Two of these struck amidships on the port side but did not explode. All attacking aircraft returned safely, confirming the ineffectiveness of Musashi’s defenses at this point.
At 15:21, Helldivers targeted the Haruna, but only managed five near misses. The increasing intensity of the air attacks throughout the day indicated that Japanese land-based air forces had failed to neutralize Halsey’s carriers. Consequently, at 15:30, Kurita ordered his fleet to change course westward, away from the San Bernardino Strait, hoping that this maneuver would reduce the pressure from air attacks and allow Japanese air forces to achieve better results. Meanwhile, Bogan launched his third strike of the day at 15:50, with 31 aircraft under Ellis targeting the Musashi one final time. However, due to fatigue, the attack was ineffective. After this last air strike, Kurita decided to head back towards the San Bernardino Strait and instructed the sinking Musashi to beach itself on Sibuyan Island at 17:15. Before this could be executed, the battleship sank at 19:36, resulting in the loss of 1,023 lives. Thus, the Musashi became the largest ship ever sunk by air attack in what was the largest air-sea battle in history up to that point.
Despite losing 18 aircraft, the Americans succeeded in sinking the Musashi, torpedoing the Myoko, and damaging three other battleships to varying extents. Nevertheless, the 1st Striking Force emerged in better condition than anticipated, with the Musashi absorbing much of the torpedo and bomb damage and allowing the other ships to weather the attack. Kurita planned to navigate San Bernardino Strait during the night, proceed down the east coast of Samar, and reach Leyte Gulf around 11:00. Meanwhile, Admiral Mitscher’s search planes had located Ozawa’s carriers at 16:40. By afternoon, Ozawa had launched most of his aircraft in an attack on Sherman, but the final assault by the once formidable IJN carrier force achieved only limited success, with 28 planes lost before retreating to the Philippines. Remaining undetected, Ozawa then dispatched two battleship carriers and four destroyers under Rear-Admiral Matsuda Chiaki southward, drawing American attention to his position.
In the aftermath of the Battle of the Philippine Sea, the Americans did not know that the IJN had no prospects of replacing its lost aviators. Because the majority of the carriers themselves survived the battle, and the Americans knew other carriers were being added to the force, the IJN’s carrier force was still a threat. The intelligence Halsey received on the IJN’s carrier force indicated that it was fully capable. In every other major battle of the war, the IJN carrier fleet was the main threat. The Pacific War had become a carrier war and surface forces had been firmly supplanted as the primary striking force. The Americans had no way of knowing that the Japanese had turned this thinking on its head in their planning for Leyte Gulf. Nimitz wanted to destroy the Combined Fleet and thus gain an increased measure of operational freedom for future operations. He was disappointed that this did not occur at Philippine Sea and thus had inserted the instruction to Halsey that the destruction of the Japanese fleet would be his primary objective if the opportunity was presented. Achieving this not only would eliminate the main threat to the invasion, but it would cripple the IJN’s ability to interfere with future operations. As the assessment from the aviators was that Kurita’s force no longer posed a threat, at 19:50 Halsey ordered his entire force north to crush what he assessed as the primary threat: Ozawa’s carrier force. He decided to do so with the entirety of his force. By doing so, he decided to ignore the threat posed by the Kurita force, which was headed toward San Bernardino Strait. He kept his whole force together, because that was how TF 38 fought and because, as he stated after the war, he did not want to divide his force in the face of the enemy. A decisive victory was most likely if the carriers of TF 38 worked with the battleships of TF 34. This was USN doctrine and Halsey fully supported it.
At 20:22, Task Force 38 set course north, with the three carrier groups in the area meeting just before midnight. Earlier, at 20:05, a night reconnaissance aircraft from Independence had reported that Kurita's formidable surface force was heading back toward the San Bernardino Strait. This news raised concerns among several of Halsey’s subordinates, including Bogan and Lee, but they were dismissed by the resolute Halsey. As a result, the 3rd Fleet’s full strength continued northward toward Ozawa's decoy force, leaving the San Bernardino Strait completely unprotected. This left Kurita's battleships unopposed between themselves and the American landing vessels, except for Kinkaid’s vulnerable escort carriers off Samar’s coast. Meanwhile, the detection of Nishimura’s force on October 24 gave Kinkaid enough time to prepare for a battle at Surigao Strait. Oldendorf set up his battle line under Rear-Admiral George Weyler near Hingatungan Point in the northern part of the strait, providing maximum sea space while still constraining Japanese movement. Eight cruisers in two groups were positioned south of this line, with 24 destroyers stationed to screen the battleships and cruisers and positioned on both flanks to launch torpedo attacks against the approaching Japanese. Additionally, 39 PT boats were deployed in the southern approaches to the strait and into the Mindanao Sea to provide early warning and execute torpedo attacks when possible. The main issue was that the battleships were primarily equipped with high-explosive shells and would only engage once the Japanese forces were about 20,000 yards away. Moreover, Kinkaid had intercepted an order from Halsey to assemble a powerful task force of fast battleships. Misinterpreting the order's unclear wording, Kinkaid mistakenly believed Task Force 34 was coming to defend San Bernardino Strait, allowing his forces to concentrate on Surigao Strait instead.
Despite Kurita’s delays, Nishimura pressed on to breach the strait, advancing with the heavy cruiser Mogami and three destroyers. Little is known about Nishimura’s precise thinking as he approached the strait. He was planning on arriving off Tacloban at 0430hrs on October 25 in accordance with Toyoda’s master plan that had Kurita’s force arriving off Leyte a short time later. This schedule fell apart after Kurita’s advance was thrown off schedule on the afternoon of October 24 when he temporarily turned around in the face of intensive air attack in the Sibuyan Sea. At 2013hrs Nishimura sent a message to Toyoda and Kurita that he planned to arrive off Dulag at 0400hrs the next morning, a half hour later than planned. This was only a minor change; much more important was the receipt at 2200hrs of Kurita’s message that he would not be in the gulf until 1100hrs. This meant that Nishimura’s force was on its own when it executed its attack into the gulf. However, Nishimura did not change his plan after learning of Kurita’s revised intentions. He was determined to force the strait in darkness and in so doing draw forces away from Kurita’s main attack.
The battle began at 2236hrs when PT-131 gained radar contact on Nishimura’s main force. The three boats of the section headed toward the contact to make a torpedo attack. Two of the boats were slightly damaged, but one was able to close within torpedo range. News of the contact did not reach Oldendorf until 0026hrs on October 25. Another section sighted the advance group built around Mogami at 2350hrs and two of the boats fired a torpedo at the cruiser. Neither hit its target. Demonstrating the confusion in any night battle, at about 0100hrs Mogami was hit by a 6in. shell from Fuso. Though a dud, it killed three men. About an hour later, PT134 closed to within 3,000 yards of Fuso and fired three torpedoes. Again, all missed. This running series of encounters continued up until 0213hrs. Of the 39 boats, 30 contacted the Japanese and launched 34 torpedoes. None of Nishimura’s ships was hit. While Nishimura’s force was successfully fighting its way up the strait in good order, he kept Kurita and Shima informed of his progress. At 0040hrs, the two parts of Nishimura’s force reunited. First blood went to the Japanese, since ten PTs were hit, and one (PT-493) sank, with a total of three dead and 20 wounded. Though unable to exact any attrition on the Japanese, the PTs had provided an invaluable service informing Oldendorf of Nishimura’s location and strength.
Based on an earlier report from one of Mogami’s scout aircraft on the location and numbers of USN ships in Leyte Gulf, Nishimura appeared to believe that the battle would occur inside Leyte Gulf and not in Surigao Strait. If he really believed that Oldendorf would not use favorable geography to his advantage, he was sorely mistaken. Having survived the PT boat attacks with no damage, Nishimura now faced a much more deadly threat. This came in the form of five Fletcher-class destroyers under the command of the aggressive Captain Coward. Two other destroyers from Coward’s Destroyer Squadron 54 were left on picket duty and did not take part in the torpedo attack. The five destroyers assigned to the attack were arrayed to conduct an anvil attack (with torpedoes coming in from both bows of the enemy target), with McDermut and Monssen from the west and Remey, McGowan, and Melvin from the east. Approaching at 30 knots, Coward’s ships would launch torpedoes guided by radar, and refrain from using their 5in. guns so as not to give their positions away. Once the torpedoes were on their way, the destroyers would break off and head north along the coast to clear the area and reduce the possibility of a friendly fire incident. What ensued was one of the most successful attacks of the entire war.
Shortly after 03:00, Coward’s three eastern destroyers launched 27 torpedoes from a range of 8200 to 9300 yards at the advancing Japanese ships. They scored two critical hits on the Fuso at 03:08, causing flooding and fires. The battleship, unaware of the severity of the damage, veered off course and headed south, ultimately sinking at about 03:45 with 1620 lives lost. The Americans claimed that the torpedoes had split the Fuso in two. Meanwhile, Coward’s two western destroyers fired a full salvo of 20 torpedoes at 03:10. In response, Nishimura changed course, exposing his screen to danger. By 03:19, three torpedoes from McDermut struck the Yamagumo, which exploded and sank within two minutes; another torpedo hit the Michishio amidships, causing it to sink 15 minutes later after coming to a halt; and a final torpedo hit the Asagumo, damaging its bow and reducing its speed, forcing it to withdraw from the battle. McDermut’s ten torpedoes were the most effective salvo of the war from any American destroyer.
Monssen's torpedo attack resulted in a single hit on the battleship Yamashiro, causing some flooding and reducing her firepower by a third. Following Coward's devastating torpedo strike, six more destroyers, divided into two groups of three, approached Nishimura's force from the west along the coast of Leyte. The first group commenced their attack at 03:23, launching 14 torpedoes from a range of 6500 to 6800 yards, but only one torpedo struck the Yamashiro, temporarily slowing her to 5 knots. The second group of destroyers fired 15 torpedoes at 03:29, but none of their torpedoes hit their targets, and the gunfire from both sides proved ineffective. After this failed assault, nine destroyers in three sections of three approached Nishimura’s weakened column from both flanks. The first two sections, attacking from either side, fired a half-salvo of five torpedoes from each destroyer, but none hit. Before the final section could launch its attack, a fierce gunnery battle was underway.
The gunnery battle began at 0351hrs when the first American cruiser opened up. Two minutes later, West Virginia commenced fire from 22,800 yards. All ships fired at the largest radar return of the three Japanese ships, which was Yamashiro. The American barrage grew as each battleship gained a fire control solution. The three ships with the most modern fire control systems did most of the work. California joined in at 0355hrs from 20,400 yards followed by Tennessee one minute later. The three battleships with the less capable Mk 3 fire control radar struggled to gain a firing solution. Maryland opened fire at 0359hrs by ranging her Mk 3 radar on the shell splashes from the other battleships. Mississippi took until 0412hrs when she fired a full salvo at Yamashiro from 19,790 yards. Pennsylvania never gained a good solution for her 14in. main battery and failed to fire a single salvo. Unbeknownst to Nishimura, the Americans had executed a "T" maneuver, leaving his ships able to fire only their forward guns while the enemy could unleash full broadsides. Concentrating their fire on the Yamashiro, Oldendorf’s cruisers and battleships landed several hits during the 18-minute engagement. By 03:56, the Yamashiro was seen burning amidships, aft, and in the bridge area. Despite this, the battleship fought back fiercely, targeting the cruisers Phoenix, Columbia, Shropshire, and Denver, though no hits were achieved.
The Mogami endured severe damage during this engagement, with the cruiser Portland focusing its fire on her and inflicting heavy harm. In the early phase of the battle, she took several 5in. hits from American destroyers. In the first minutes of the withering barrage from Oldendorf’s cruisers and battleships, Mogami sustained more damage, including a hit on one of her 8in. turrets. After firing four Type 93 torpedoes at 0401hrs against the gun flashes from enemy ships to the north, she came under fire from heavy cruiser Portland. Two 8in. shells hit Mogami’s bridge at 0402hrs, killing her commanding officer, and other shells disabled two engine rooms. The new commanding officer decided to break off the action and head south at slow speed. While headed south, she encountered the Second Diversion Attack Force.
As American gunfire pummeled Yamashiro’s superstructure, the last destroyer group approached head-on, closing to within 6200 yards before launching 13 torpedoes. Before the torpedoes could reach their targets, the destroyers came under friendly fire and further assault from Yamashiro’s guns, resulting in the Albert W. Grant taking 18 hits before being withdrawn. Observing the friendly fire, Oldendorf ordered a ceasefire at 04:09, allowing Nishimura to begin a retreat south. However, by 04:11, the Yamashiro had been hit by three torpedoes from the final destroyer salvo, causing a severe list and bringing the battleship to a halt. Yamashiro’s valiant yet ultimately futile resistance ended at 04:19 when she capsized to port, taking Nishimura and 1625 others with her.

The largest naval battle in human history had only just begun. As many historians argue, given the fateful decision of Halsey to try and knock out the IJN combined fleet, the transports had been left completely open to an attack. Absolute carnage could unfold on an unprecedented scale…perhaps enough to cause America to rethink continuing the war?

- 152 - Pacific War Podcast - Return to the Philippines 17 - October 21 - , 1944
15 10月· The Pacific War - week by week
Last time we spoke about the Formosa air battle. In mid-1944, General MacArthur and Admirals Nimitz and Halsey debated their next move in the Pacific. MacArthur, intent on a direct assault on the Philippines, clashed with Nimitz, who favored invading Formosa. MacArthur's persuasive tactics, political savvy and to be more blunt, threats during a rather dramatic visit to Honolulu, convinced President FDR to prioritize the Philippines. Despite MacArthur's grandstanding, FDR did not completely abandon the US Navy’s plans, and MacArthur's plan would require significant Naval support, with carrier strikes planned to soften Japanese defenses. In October, Halsey’s carriers launched devastating strikes against Formosa, leading to heavy Japanese losses and disrupting their air power. Despite some fierce counterattacks and damage to American ships, including the cruiser Canberra, the American forces achieved air supremacy. The successful air campaign set the stage for the invasion of Leyte, marking a pivotal shift in the Pacific War.

We last left off the week before the grand return to the Philippines, Admiral Halsey had dispatched his carrier forces to neutralize enemy bases in Formosa in preparation for General MacArthur’s Leyte invasion. However, Admiral Toyoda's response was unexpectedly strong, resulting in two cruisers being torpedoed, which forced Admiral Mitscher to order a retreat eastward under pressure from Japanese aviators. On October 15, while the cruisers Houston and Canberra were being towed under the protection of Admiral McCain’s carriers, Halsey directed Admirals Bogan and Sherman’s task groups to withdraw eastward out of sight. At the same time, Admiral Davison’s forces carried out intermittent air raids on northern Luzon to keep enemy aircraft at bay.
More significantly, Halsey decided to turn the situation into an opportunity. He instructed McCain’s units to send out open messages, pleading for assistance. This tactic, which Halsey called the "Lure of the Streamlined Bait," was designed to mislead the Japanese into believing that this task group was all that remained of the fleet, enticing them to move in for the kill. Halsey’s other task groups, which had withdrawn eastward, would then return to engage and destroy the enemy. On October 14, Japanese aviators claimed two carriers, one battleship and one heavy cruiser sunk, and one small carrier, one battleship and one light cruiser set afire. The exaggerated claims of the Japanese air force were accepted jubilantly on the home islands. The people felt that the American Navy had indeed been given a death blow, and the Finance Ministry distributed "celebration sake" to all households in the country to commemorate the event. The Tokyo radio made the unfounded claim that "a total of 57 enemy warships including 19 aircraft carriers and four battleships were sunk or heavily damaged by the Japanese forces… the enemy task forces lost the majority of their strength and were put to rout." It also predicted that the Allied losses would delay the invasion of the Philippine Islands by two months. Admiral Halsey's reaction was to report that "all 3rd Fleet Ships reported by radio Tokyo as sunk have now been salvaged and are retiring towards the enemy." The exaggerated claims of success made by Japanese pilots further convinced Toyoda to continue the assault, despite heavy aircraft losses. Meanwhile, Admiral Shima’s strike force was already rushing south from the Inland Sea to support the air forces. However, Shima's force was not the only one speeding towards the battlefront.
On October 13, Admiral Barbey’s convoy, consisting of over 470 ships and carrying the 24th Division and the 6th Army Service Command, finally departed Hollandia, heading toward the designated "Far Shore," Leyte. The next day, the convoy crossed the equator without ceremony. By October 15, Task Force 78, which included the 1st Cavalry Division, joined the massive convoy. With General Sibert’s full 10th Corps now en route to Leyte, the plan was to rendezvous with Admiral Wilkinson’s Task Force 79. Over the course of about two weeks, General Hodge’s 24th Corps had been transported from Hawaii to Eniwetok and then to Manus Island. On October 11, the LSTs carrying the assault battalions departed Manus, followed by Wilkinson’s convoy of 267 ships, which left the Admiralties three days later. Their progress was steady, and by October 17, Wilkinson’s tractor groups began joining the 7th Fleet. This combined fleet formed the largest convoy ever seen in the Pacific up to that point.
Meanwhile, during the Formosa Air Battle, Japanese aviators launched multiple strikes against Task Groups 38.1 and 38.4 from dawn to dusk on October 15. Fortunately, the American carriers' reinforced combat air patrols effectively minimized damage, with only one glancing bomb hit on the Franklin. In retaliation, Admiral Mitscher’s pilots claimed to have shot down more than 100 Japanese planes. Additionally, Admiral Davison’s carriers attacked enemy air concentrations in Luzon, though they faced heavy resistance from Vice-Admiral Teraoka Kinpei’s reorganized 1st Air Fleet. These engagements continued over the next two days, with American forces estimated to have destroyed 99 enemy aircraft on the ground and 95 in the air by October 19.
On the morning of October 16, Mitscher’s carriers conducted long-range searches to determine if the enemy had fallen for Halsey’s trap. Meanwhile, Japanese morning reconnaissance flights over the western Philippine Sea spotted three enemy task groups with a combined total of 13 carriers in the vicinity, forcing Toyoda to reluctantly cancel Shima’s planned attack. As a result, no surface engagement materialized from Halsey's "Lure of the Streamlined Bait." However, 247 naval aircraft were promptly dispatched from Okinawa, Formosa, and Luzon to locate the enemy groups. McCain continued to fend off persistent Japanese air assaults, which managed to land another torpedo hit on the Houston. Hellcats from light carriers Cabot and Cowpens did great execution against a Japanese formation of over 100 aircraft. However, three Jills penetrated the screen. One twin engine plane fought through the CAP and ships' anti-aircraft batteries, surviving just long enough to put a torpedo in the water before the plane itself crashed into the sea. The torpedo struck the after portion of the starboard side of the Houston, blowing 20 men overboard and spreading gasoline fires in the waters around the cruiser. The explosion set fire to the starboard tank that held fuel for the ship's reconnaissance floatplanes, causing a major fire in the aircraft hangar, though the remaining crew suppressed the blaze within fifteen minutes. Flooding from this hit degraded the ship's buoyancy and stability further. Another 300 men were evacuated afterward, leaving just 200 aboard to continue damage control efforts as the ships withdrew. Despite the cruiser suffering significant damage, the towing operation carried on, slowly guiding the task group towards Naval Base Ulithi, which they eventually reached on October 27.
On October 17, the Japanese were still in pursuit of the retreating fleet, but contact was lost, and further attacks were aborted. Nevertheless, the Formosa Air Battle had one final chapter. After the successful strike on Okayama on October 14, General LeMay deemed the damage extensive enough that it wasn’t necessary to send all available B-29s for mop-up operations. On October 16, only the 444th and 462nd Bombardment Groups were dispatched to hit Okayama, while the 468th targeted Heito, an airbase and staging field east of Takao. Of 49 planes airborne against Okayama, only 28 bombed there, but they were aided by five stragglers from the 468th Group. To even things up, a formation of 11 planes from the 444th flew calmly by its Okayama target and struck at Heito through an error by the lead bombardier. Other B-29s bombed alternate or chance targets at Takao, Toshien, Swatow, and Sintien harbors; at Hengyang; and at several airdromes, including Taichu on Formosa. This dual mission was less smooth than the October 14 raid, but no losses were reported. The next day, 23 B-29s from the 40th Bombardment Group attacked the Einansho Air Depot near Tainan to complete the Formosa campaign. Heavy cloud cover prevented 13 of the bombers from reaching the target, so they diverted to bomb Takao harbor instead. Despite these challenges, LeMay’s bombers inflicted significant damage overall.
By the end of the Formosa Air Battle, the Japanese had launched a total of 761 offensive sorties. Toyoda’s pilots reported that nearly the entire 3rd Fleet had been sunk and the American carrier force was in ruins. For comedic effect why not go through the real list shall we: Japanese claims were finally listed as follows: Sunk: 11 carriers, 2 battleships, 3 cruisers, 1 destroyer (or light cruiser). Damaged: 8 carriers, 2 battleships, 4 cruisers, 1 destroyer (or light cruiser), 13 unidentified ships. In addition, at least 12 other ships set afire. These exaggerated claims were heavily promoted by newspapers, although figures like Toyoda within the IJN remained skeptical. In reality, the Japanese air forces were decisively beaten at Formosa, losing around 171 planes in the initial defense and another 321 during attacks on Mitscher’s fleet—a total of approximately 492 aircraft.
The Second Air Fleet, comprising the main strength of the Navy's base air forces, had lost 50 per cent of its strength and was reduced to 230 operational aircraft. The First Air Fleet and Fourth Air Army in the Philippines were left with a combined operational strength of only a little over 100 aircraft. Of 143 carrier planes used to reinforce the Second Air Fleet, about one-third, with their flight crews, had been lost.
Allied estimates, however, place Japanese losses as high as 655. In addition to these aircraft losses, Japan suffered significant casualties among air personnel, which severely weakened Admiral Ozawa's 3rd and 4th Carrier Divisions and left General Yamashita with limited air support for the defense of the Philippines. On the other hand, Halsey’s forces lost only 89 aircraft, with two cruisers suffering serious damage. The radar-guided Hellcats easily repelled the fragmented Japanese attacks, causing no delays to the American operations and inflicting no serious damage on Task Force 38. This defeat significantly diminished Japan’s ability to defend the Philippines, as their surface forces were now left without effective air cover. In the aftermath of the battle, the aggressive Vice-Admiral Onishi Takishiro assumed command of the 1st Air Fleet and initiated the creation of a suicide corps, recruiting volunteers to dive-bomb enemy vessels. Thus, the Kamikaze Special Attack Corps was born. Captain Motoharu Okamura, in charge of Tateyama base and the 341st Air Group Home is theorized to be the first officer to propose the use of kamikaze attack tactics. Commander Asaichi Tamai asked a group of 23 student pilots whom he had trained to volunteer for the first special kamikaze attack force, all of them did so willingly. The names of the four subunits within the Kamikaze Special Attack Force were Unit Shikishima, Unit Yamato, Unit Asahi and Unit Yamazakura.
LeMay reported the destruction of 65 buildings and damage to 9 out of the 80 at Okayama’s assembly plant, along with the destruction of 7 hangars and 16 buildings and damage to 9 others at the airbase. As a result, LeMay’s intelligence team estimated it would take between four and six months to fully restore the Okayama plant to full operational capacity. His final strike of the month occurred on October 25, targeting the Omura Aircraft Factory, with 78 B-29 bombers successfully taking off. Over Omura, 59 planes dropped 156 tons of bombs, while 11 hit various other targets. Despite moderate resistance, one bomber was lost during the attack. Strike photos and subsequent reconnaissance showed significant damage, especially in the aluminum fabrication area. Over the following three months, Omura would become a primary target for Operation Matterhorn, though the 20th Bomber Command also conducted additional strikes to support Allied operations in Southeast Asia, China, and the Philippines.
Meanwhile, minesweepers and other vessels had cleared the way for amphibious flotillas. In the early dawn of October 17 the minesweepers began their work on the channel approaches to Suluan Island. By 06:30 they had accomplished their task and then began to sweep the waters of the landing areas in Leyte Gulf until the storm forced them to suspend operations. At 12:59 they resumed sweeping with great difficulty. Until A Day, intensive area and tactical mine sweeping continued. The sweepers started at dawn each day and worked continuously until nightfall. By October 19 it was known that the Japanese had heavily mined the approaches to Leyte Gulf but that there were no mines within the gulf itself. However the northern part of the main channel into the gulf was not considered safe. By the same date sweeping had been completed in the southern half, 186 mines having been destroyed. At about 01:35 on October 19, the destroyer supporting the mine-sweeping units which were in the gulf struck a floating mine and while maneuvering away from the area struck another. The ship was disabled and retired from action. By A Day, a total of 227 mines had been destroyed and a passage approximately six miles wide had been cleared just north of Dinagat Island. All ships were therefore directed to enter Leyte Gulf through that portion of the strait. As the minesweepers came close to the land, boats containing Filipinos moved out to welcome the advance party of liberators. The reception they met was not enthusiastic. Admiral Oldendorf "suspected that some might have come seeking information so detained them aboard their respective ships… Directed no further patriots be taken aboard ship."With Halsey’s forces still in the Formosa-Ryukyus region, these ships were under the air cover of General Whitehead’s 5th Air Force and Admiral Kinkaid’s escort carriers. While minesweepers and demolition teams worked to clear mines, remove transport barriers, and perform beach reconnaissance, Company D of the 6th Ranger Battalion prepared to land on Suluan Island on October 17. Supported by fire from the USS Denver and in heavy rain, the Rangers successfully landed on the beach at 08:05 without opposition. The men immediately filed south 500 yards on a trail along the coast and then headed east toward the lighthouse. On the way, four buildings, one of which contained a Japanese radio, were found and set ablaze. The company then continued along the trail. Suddenly the enemy fired from a concealed position, killing one man and wounding another. When Company D went into attack formation, the enemy force disappeared into the heavy jungle bordering the trail. The march was resumed and the company reached its objective without further incident. The lighthouse, which had been damaged by naval bombardment, and adjoining buildings were deserted.
Unfortunately, a Japanese radio station successfully reported the enemy convoy’s approach and the start of the Rangers’ landings, revealing that Leyte was the Americans' ultimate target. In response, Toyoda swiftly initiated Operation Sho-Go, ordering Vice-Admiral Kurita Takeo’s 1st Striking Force to move from Lingga anchorage to Brunei Bay, preparing to strike the enemy invasion fleet. Just after midnight on October 18, Kurita’s ships departed Lingga anchorage and began their trek to Leyte. Sentai (Division) 16—heavy cruiser Aoba, light cruiser Kinu, and destroyer Uranami—was ordered to detach from Kurita’s command and head to Manila. These ships were all among the oldest in Kurita’s fleet, but it was a mistake to detach them for a secondary transport mission when they would have been better used to augment the decisive attack planned for Kurita’s force.
Simultaneously, Shima’s 2nd Striking Force, reinforced by Kurita’s detached 16th Cruiser Division, was tasked with supporting counterlandings. The Second Striking Force, for this newly-assigned mission, was to be composed only of the Fifth Fleet (two heavy cruisers, one light cruiser, seven destroyers) plus the 16th Cruiser Division (one heavy cruiser, one light cruiser, one destroyer) detached from the First Striking Force. Under this plan, the 16th Cruiser Division was ordered to proceed to Manila, while the Second Striking Force main body, then at Amami Oshima in the Ryukyus, was ordered to go first to Mako, refuel, and then proceed to the Philippines.
By noon, another order was issued to Ozawa’s Main Body, despite its depleted air power, to coordinate a sortie from home waters in support of the attack planned for the morning of October 25 in Leyte Gulf.
The mission of the Ozawa force was of vital importance to the success of the over-all plan. It was to act as a decoy to draw off the main strength of the enemy naval forces covering the invasion operations in Leyte Gulf, thus allowing the 1st Striking Force to penetrate to the landing point and smash the enemy's troop and supply ships. To heighten its effectiveness as a lure, the Ozawa Force sortied with all of the 3rd Carrier Division, made up of the regular carrier Zuikaku and the light carriers Zuiho, Chitose, and Chiyoda. The total number of aircraft available to put aboard these ships, however, was only 108. These belonged to the poorly trained air groups of the 1st Carrier Division and represented about half the normal complement. In addition to the half-empty carriers, the force comprised two battleships, three light cruisers and eight destroyers. Ozawa fully anticipated that his fleet would be completely wiped out, but this sacrifice was deemed essential to achieve the primary objective: destruction of the entire enemy invasion force. As a result of the transfer of the flying groups of the 3d and 4th Carrier Divisions to Second Air Fleet for the Formosa air battle, the Task Force Main Body had lost much of its planned striking power. The mission assigned to it was therefore less offensive than that assigned in the original Sho-Go battle plan. The original plan had called for a diversionary attack by the Ozawa Force against the enemy's main carrier task forces. Under the more general terms of the 18 October plan, however, Vice Adm. Ozawa was left discretion to choose an attack target more commensurate with the strength of his force.
Meanwhile, Davison’s carrier aircraft launched attacks on air bases around Manila and Legaspi, but neither the 1st Air Fleet nor the 4th Air Army could respond due to adverse weather. As these strikes were carried out in difficult conditions, General Terauchi concluded by nightfall that a significant enemy operation was underway. He then activated the Army component of Sho-Go, instructing Lieutenant-General Tominaga Kyoji to target enemy ships near Leyte. Should the enemy successfully land, General Suzuki’s 35th Army was ordered to delay their advance until reinforcements arrived, with the goal of launching a counterattack to defeat the Americans by October 25. Given the recent actions on Suluan and the American naval presence in the Leyte Gulf, the Army and Navy IGHQ sections surprisingly coordinated their response, with the IJA staff approving the Southern Army’s request to implement Sho-Go 1. It was determined that the coming decisive battle for Japan was the Philippines. One major difference was the battle’s location. Terauchi, Yamashita, and other Southern Army officers believed it would be Luzon, not Leyte. With Sho-Go 1 focused on Leyte, the Japanese would have to fight in the central Philippines, without extensive defensive works or major airfields. Yamashita would also use his limited shipping to send reinforcements to Leyte. If the Japanese lost Leyte, there might not be sufficient strength to defeat decisively any American offensive on Luzon. Deploying the few IJA units to Leyte would make a Luzon defense harder to accomplish. Sho-Go 1 could hand the control of the Philippines to the Americans. Eventually, Terauchi agreed to the IGHQ position of making Leyte the primary location to fight the Americans. Believing that Halsey’s fleet had been defeated off Formosa, Terauchi now thought the Americans could not sustain any major operations or contest reinforcement convoys, both poor assumptions that would later cause suffering for the IJA. Yamashita disagreed with Terauchi and the IGHQ about designating Leyte as the prime battle site; but on October 22, Terauchi finally ordered Yamashita and the Fourth Air Army to make Leyte the main point of attack. His opinion was: “The opportunity to annihilate the enemy is at hand.” However Yamashita was convinced that the Americans had greater strength than anticipated, given the continued American carrier aviation’s presence.
Meanwhile, by 12:30 on October 17, the Rangers had successfully landed on Dinagat Island, finding no Japanese forces there. On the morning of the 18th, the ship's address system clanged out general quarters. The men went below, put on their gear, and checked their weapons. At 0900 the troops were told to prepare to disembark. They bolted up the ladders and spilled out over the deck to the davits. The boats were lowered and the first wave started for the beach. At the same time the guns from the destroyer and frigate which had escorted the transport concentrated fire against the shore line for twelve minutes. Three minutes later, the boats grounded on a coral reef forty yards from the beach, and the men waded the remaining distance to shore. They encountered no resistance and at 1038 the company commander, Capt. Arthur D. Simons, notified the battalion commander, "Beachhead secured, supplies ashore. No resistance. No casualties." The company set up a channel light. They quickly set up a navigation light at Desolation Point to guide the main convoy. However, bad weather and tides delayed the landing on Homonhon Island. Colonel Mucci’s Company B finally made it ashore the next morning without opposition and installed another navigation light. At the same time, Tominaga attempted to retaliate but was thwarted by a violent storm. In the afternoon, Kinkaid’s forces, supported by Mitscher’s carriers, conducted minesweeping and direct-fire missions on the Leyte beaches to protect the underwater demolition teams. Admiral Oldendorf’s warships heavily bombarded the southern beaches, paving the way for transports to enter Leyte Gulf by the following evening.
These pre-landing operations, which continued through October 19 on the northern landing beaches, alerted General Makino to a potential secondary landing closer to Tacloban. This maneuver would outflank the main strength of the 16th Division and directly threaten his headquarters. In response, Makino relocated his headquarters from Tacloban to Dagami and ordered the 33rd Regiment to reinforce the Palo-San Jose coastal sector, while the 2nd Battalion strengthened the southern defenses. Despite these last-minute efforts, Makino’s forces were unprepared for the overwhelming assault. The heavy naval gunfire had destroyed many defensive positions and disabled most of the 22nd Field Artillery Regiment’s guns. Furthermore, although the weather now favored Tominaga’s counterstrikes, American carrier operations had been so effective that he was unable to challenge their air superiority.
Despite the optimism of the High Command with regard to the prospects of gaining eventual air superiority in the battle area, it was already evident that the air phase of Sho-Go was not working out as intended. Those plans had envisaged mass air attacks against the invading enemy naval forces and troop convoys beginning prior to their arrival at the landing point. The enemy, however, had forestalled these plans by striking at Leyte before the planned concentration of Japanese air strength in the Philippines had been completed, and before the Navy's base air forces had time to recover from losses sustained in the Formosa Air Battle and earlier enemy carrier strikes on the Philippines. The 1st Air Fleet, already in the Philippines, had been reduced to an operational strength of less than 50 aircraft. The 2nd Air Fleet, which had lost half its strength in the Formosa Battle, had not yet begun its redeployment from Formosa to the Philippines. Although the 4th Air Army had sustained relatively lighter losses, its strength was widely dispersed. Before it could operate effectively in the Leyte area, it had to concentrate at forward bases in the central Philippines, an operation rendered both difficult and dangerous by enemy action, bad weather, and the virtually useless condition of many of the forward fields due to continuous rains. Under such unfavorable conditions, the concentration required a minimum of several days, and in the meanwhile the enemy was able to operate in Leyte Gulf against extremely light air opposition. On October 19, when weather conditions finally permitted an air attack against the enemy invasion fleet, no more than five naval and three Army aircraft could be mustered against the steadily increasing concentration of enemy shipping in Leyte Gulf.
By the evening of October 19, the preliminary operations were nearly complete, with most of Kinkaid’s fleet positioned outside the gulf. Since the minefield at the entrance hadn't been fully cleared, the ships entered slightly south of the entrance's center, avoiding the main channel and staying close to Dinagat's northern point. Meanwhile, Suzuki had already activated the Suzu Plan, with units from the 30th and 102nd Divisions preparing to move toward Ormoc. However, before they could depart, Oldendorf began October 20 with two simultaneous pre-landing bombardments, each involving three battleships. After two hours of battleship fire, cruisers and destroyers followed with high-explosive shells, causing significant damage. At the same time, Kinkaid’s escort carriers launched bombing and strafing runs against suspected defensive positions and airfields, severely disrupting Makino’s radio and telegraph communications. At 0800 the first anchor chains of the vessels had rattled out; LCVP's were quickly swung over the sides; boats circled mother ships and moved to their rendezvous areas. The LCI mortar and LCI rocket ships took their places at the head of the assault waves. It was now 0945, fifteen minutes before H Hour. The LCI's raced simultaneously to the shores of Leyte, raking the landing beaches with rocket and mortar fire. The bombardment grew heavier and more monotonous. Hundreds of small boats, flanked by rocket ships and destroyers, headed toward the beaches; thousands of rockets hit the beaches with the rumble of an earthquake. It was impossible to distinguish one explosion from another in the unbroken roar. By 09:30, the 21st Regiment successfully landed on Panaon Island without resistance, securing control of the entrance to Sogod Bay. Fifteen minutes later, the transports sped toward Leyte's shores, led by LCI gunboats, which pounded the beaches with rockets and mortar fire. At 10:00, Sibert’s 10th Corps, covered by a heavy rocket barrage, landed on the White and Red Beaches, marking the Americans' return to the Philippines.
Admiral Fechteler’s transports delivered General Mudge’s 1st Cavalry Division to White Beach, where the brigades landed side by side, with the 8th Cavalry Regiment held in floating reserve. Facing only small arms and machine gun fire, the 1st Squadron of the 7th Cavalry Regiment swiftly secured the Cataisan Peninsula and its airfield, while the 2nd Squadron captured San Jose and advanced across the Burayan River, reaching a point 3000 yards from the beach. The 5th and 12th Cavalry Regiments had to navigate a deep swamp to access Highway 1, then pushed westward until they encountered enemy resistance near the foothills of Caibaan. At 10:40, Mudge’s reserve began to land, followed by the division artillery at 13:30. Meanwhile, to the south, Barbey’s transports landed General Irving’s 24th Division on the shallow Red Beach, with the 19th and 34th Regiments landing abreast in battalion columns. The Japanese permitted the first five waves to land, but when the remaining waves were about 2000 yards offshore, they unleashed heavy artillery and mortar fire, sinking several landing craft and causing significant casualties.
The first elements of the 3d Battalion, 34th Infantry, inadvertently landed 300 yards north of the assigned area and were immediately pinned down by heavy machine gun and rifle fire. The commanding officer of the regiment, Col. Aubrey S. Newman, arrived on the beach and, noting the situation, shouted to his men, "Get the hell off the beach. Get up and get moving. Follow me." Thus urgently prompted, the men followed him into the wooded area. To the south the 19th Infantry, with the 3d Battalion in the lead, had also struck heavy opposition on its sector of the beach. Through error the first waves of the regiment landed almost directly behind the 34th Infantry and 800 yards north of the proposed landing point. The later waves landed at the planned spot. Company K did not land on schedule, because its command boat broke down. Going in under heavy fire, the company had all its officers except one killed or wounded. One of its platoons was unable to make contact with the rest of the company until the following day. Upon landing, the first waves were immediately pinned down by intense machine-gun and rifle fire. Despite this, the Americans successfully stormed the initial defenses of the 33rd Regiment. By 12:15, the 34th Regiment had cleared the beach of enemy forces, and after a preparatory concentration, its 3rd Battalion advanced approximately 400 yards. The 2nd Battalion then moved through the 3rd, crossed Highway 1 at 15:50, and established positions for the night 100 yards west of the highway.
To the south, the 3rd Battalion, 19th Regiment had reached Highway 1, while the battered 1st Battalion followed behind under heavy fire. Meanwhile, the 2nd Battalion landed and advanced cautiously, as the 1st Battalion pressed toward Hill 522 amidst fierce resistance. Hill 522, which rose directly from the river's edge north of Palo, overlooked the landing beaches and its upward trails were steep and winding. Hill 522 presented the most significant terrain feature which would have to be overcome before the American forces could push into the interior from Palo and it constituted one of the chief objectives for A Day. Three months earlier General Makino had started to fortify it, impressing nearly all of the male population of Palo for the work. By A Day they had constructed five well-camouflaged pillboxes of rocks, planking, and logs, covered with earth. Numerous tunnels honeycombed the hill; the communications trenches were seven feet deep. They eventually encircled enemy positions and began to make steady progress up the hill. By dusk, Companies B and C had captured the hill’s crests and successfully repelled several enemy counterattacks. This achievement secured Hill 522, which commanded the route into the interior and overlooked Palo, the gateway to Leyte Valley. At 14:30, General Douglas MacArthur landed on Red Beach alongside President Sergio Osmeña, who had taken over from Manuel Quezon following his death on August 1. So if you go on Youtube you can see the footage of MacArthur et al wading ashore and to this day there is a monument to this iconic moment.
MacArthur made a radio broadcast to the Filipino people, declaring, “People of the Philippines: I have returned. By the grace of Almighty God our forces stand again on Philippine soil—soil consecrated in the blood of our two peoples. We have come dedicated and committed to the task of destroying every vestige of enemy control over your daily lives, and of restoring upon a foundation of indestructible strength, the liberties of your people” He had finally fulfilled his promise to the Filipino people. Further south, Hodge’s 24th Corps encountered more resistance as it landed on Orange, Blue, Violet, and Yellow Beaches at 10:00. Under the transport of Rear-Admiral Forrest Royal’s ships and the protection of LCI gunboats, General Bradley’s 96th Division landed with its regiments positioned between the Calbasag River and the town of San Jose. The 382nd Regiment successfully disembarked on the Blue Beaches at 09:50, followed by the 383rd Regiment on the Orange Beaches ten minutes later.As they advanced inland, both units faced intermittent mortar and artillery fire from the 9th Regiment positioned on Catmon Hill. Colonel Macey Dill’s 3rd Battalion initially encountered obstacles such as tank barriers made of coconut logs, debris on the beach, and heavy bombardment from Hill 120. However, with mortar and naval gunfire support, the battalion eventually captured the hill and repelled several enemy counterattacks, though they were unable to continue the advance due to deep swamps. In contrast, Dill’s 2nd Battalion managed to push about 2,500 yards inland despite the intense heat and swampy conditions.
To the north, Colonel Edwin May’s 1st and 2nd Battalions were similarly hindered by an unexpected swamp but still succeeded in securing San Jose and the head of the Labiranan River, advancing approximately 2,600 yards inland. By 18:00, Bradley’s artillery had been landed, although the 381st Regiment remained in floating reserve. Further south, Admiral Conolly’s transports landed General Arnold’s 7th Division between the Calbasag and Daguitan Rivers, with regiments landing side by side. Companies L and K of the 3rd Battalion, 32nd Regiment landed abreast. Company L, on the left, ran into heavy fire from Japanese machine gunners who had waited until the leading elements of the company exposed themselves. The Japanese were entrenched in bunkers emplaced in hedgerows and banana groves. The pillboxes, which were mutually supporting, were located at the ends of the hedgerows and occasionally in the middle of an open field. Each pillbox had machine guns and anti-tank guns. Company L suffered a number of casualties and was pinned down. The enemy gunners then turned to Company K and stopped its forward movement. In the space of 15 minutes, 2 officers and 6 men of the 3rd Battalion were killed, and 1 officer and 18 men wounded. Of the medium tanks that had come ashore at 10:30, 3 were sent to support Company L and 2 to support Company K. The latter 2 were knocked out before they could adjust their fire on the pillboxes. The leading tank sent in support of Company L was knocked out by a direct hit from an antitank gun. With 2 tanks remaining, it was decided to hit the flanks of the entrenched pillboxes at 13:45. A platoon of Company K went to the right and another platoon from the company to the left. Simultaneously the remaining elements of the 2 companies, coordinating with the tanks, assaulted the pillboxes. The heavy volume of fire kept the enemy guns quiet until they could be finished off with grenades. The pillboxes were knocked out without further casualties. Paralleling the route of advance of Company L were several hedge fences, behind which were enemy machine guns and mortars. Although under heavy fire, the company was able to break through the first barriers with the aid of the tanks. At 16:30, since the enemy fire continued in volume, the 32nd Regiment withdrew and established a defensive position for the night. Meanwhile, the 184th Regiment landed its 3rd Battalion at Yellow Beach 2, directly in front of Dulag, and its 1st Battalion at Yellow Beach 1, which was farther south and separated by a swamp. Both beaches saw surprisingly little resistance, allowing the 184th to advance more quickly than expected, successfully capturing Dulag and reaching its airfield.Behind them, the reserve 2nd Battalion and the 3rd Battalion of the 17th Regiment landed after midday. The 3rd Battalion pushed west and south with minimal opposition, successfully securing the bridge over the Daguitan River at Dao.
By the end of the day, both corps had fallen short of their beachhead objectives, with Hodge’s 24th Corps achieving particularly modest results. Despite this, the Sixth Army had successfully landed assault forces along the entire eastern coast of Leyte and gained control of Panaon Strait, with casualties totaling 49 killed, 192 wounded, and 6 missing. Most of the 16th Division had retreated during the naval and air bombardment before the landing, which allowed the Americans to secure most coastal defenses before the enemy could regroup. Consequently, the only Japanese forces encountered were those left behind to delay the invasion. A more substantial enemy engagement was yet to come. Air opposition to the invasion was minimal, as Tominaga and the naval air forces continued to concentrate their strength in the Philippines in preparation for a major air offensive scheduled to begin on October 25. However, 37 Army and Navy planes attacked the invasion shipping off Leyte. At 1600, on 20 October an enemy torpedo plane was sighted as it aimed its torpedo at Honolulu. Despite the skillful maneuvering of Captain Thurber to evade, the torpedo found its mark on her port side. 64 men were killed and 35 were injured. Flooding caused a temporary severe list, but the ship was saved by efficient damage measures. But Honolulu was out of the fight. Honolulu sailed out the next day, arriving at Manus on 29 October for temporary repairs, and then steamed for Norfolk, Virginia, on 19 November, arriving on 20 December via Pearl Harbor, San Diego, California, and the Panama Canal.
Unfortunately, not all went well with logistics. Although 107,450 tons of supplies had been landed on Leyte by the end of A-Day, it was a haphazard operation. The Navy was responsible for transporting the troops and supplies to the target area. Ships' companies unloaded the cargo from the cargo vessels and transported it in small craft to the beaches. Many of the ships had been improperly loaded for the journey to Leyte. The cargo should have been so loaded that articles first needed would be the last put on board; instead it had been stowed haphazardly, with little attention given to the problem of unloading. As a result of the faulty stowage of supplies on the ships, many badly needed items were at the bottoms of the holds, and articles that would not be needed until later in the operation were piled on top of them. The supplies were set ashore in random fashion and then were carelessly thrown on trucks and other vehicles. This sort of handling resulted in a loss of carrying capacity, in slow removal of the loads, and in a consequent delay in the return of vehicles to the landing beaches. Thus, officers complained about the disorganized effort to deliver, store, and distribute supplies. This was a precursor of future resupply problems. As the landings proceeded about as smoothly as could be hoped, Halsey would order Task Groups 38.1 and 38.4 to head to Ulithi on October 22, as he doubted that the Japanese would mount a major operation in response to the American invasion. And yet, the Japanese were about to come calling for another decisive battle.

General Douglas MacArthur had finally done it, he had returned to the Philippines making good on his promise to the Filipino people. It was a colossal effort and thus far it was going very well all things considered. However little did the Americans know, but the IJN was about to toss the kitchen sink at them, literally, in an all or nothing battle to the death.

8 10月· The Pacific War - week by week
Last time we spoke about the conquest of Angaur and the Japanese Triumph in China. By October 18th, the remaining Japanese on Angaur were compressed into a small area, and by the 21st, resistance had ceased. The Americans suffered 264 killed and 1,355 wounded, while approximately 1,300 Japanese were killed. Over in China, Hara's forces suffered heavy losses during a delaying action at Momauk, with troops joining Bhamo's defense by November 16. The 113th Regiment maneuvered to encircle Bhamo from the south, while the 114th Regiment approached from the north, creating a loose encirclement. The 22nd Division's movement prompted concerns of severing key rail lines, leading Japanese forces to reposition defensively. Despite intense fighting, including a strong Chinese offensive on November 19, the Japanese withdrew from key positions, allowing Chinese forces to capture Mangshi and secure a strategic airfield for resupply, significantly impacting the campaign's dynamics.

As we last saw on Peleliu, General Rupertus' 1st Marine Division, bolstered by Colonel Dark's 321st Regiment, successfully secured the island after approximately two weeks of intense fighting. However, Colonel Nakagawa's isolated and outnumbered garrison continued to resist in the Umurbrogol Pocket. As left by nature, the Umurbrogol Pocket was much like the Ibdi Pocket on Biak Island, but larger and rougher. Like Ibdi, the Umurbrogol originally had a thick cover of tropical trees and dense jungle undergrowth which, as the result of continued air, naval, and artillery bombardment (including extensive employment of aerial napalm strikes), was gradually knocked down or burned away. Again, as on Biak, the Japanese had improved upon nature. There were many artificial or semi-artificial caves which had been constructed to protect approaches to the inner sections of the pocket, and the Japanese had improved almost every natural cave. Where no caves were available or could be constructed, the defenders employed rock faults and crevices for defensive positions. Digging new entrances to existing caves or even cutting new levels within some caves, the Japanese were well prepared to execute a long and bloody holding action along the many ridges. These ridges, with the exception of the Five Sisters group at the southern side of the pocket, were generally parallel and oriented north-northeast to south-southwest. Steep-sided and fissured, many of them had razor-back summits upon which no cover could be found. The ridges were separated by deep draws, gullies, and wider valleys, the floors of which were strewn with coral boulders or coral outcroppings similar to stalagmites. Steep as they were, the sides of some ridges also were covered with such chunks and outcroppings.
In late September, the exhausted infantrymen, who were tasked with containing the pocket while the Marines cleared northern Peleliu, made several heavy assaults. They only managed to reach the X-ray phase line, marking what was believed to be the northern edge of the core Japanese defenses, before being relieved by the 7th Marines. With Colonel Hanneken's 1st and 3rd Battalions now holding the X-ray line, Rupertus planned a strong attack southward while other Marine units maintained their positions on the western and southern sides of the pocket. On the morning of September 30, the attack was launched. However, fierce Japanese resistance, heavy rain, fog, and sickness hindered the 7th Marines' progress southward by October 2. On the following day, Hanneken's 2nd Battalion, supported by tanks, secured a foothold along the eastern side and top of Walt Ridge, while the 3rd Battalion finally captured the eastern slope of Boyd Ridge. By October 4, however, the 7th Marines had suffered such heavy losses and were so depleted that Rupertus was left with no choice but to relieve them as well.
As a result, Colonel Harris’s 5th Marines were once again thrust into action. On October 7, following an hour-long artillery and mortar barrage, the 3rd Battalion, along with six tanks, advanced into Mortimer Valley. However, Nakagawa’s determined defenders continued to resist fiercely, successfully repelling two powerful tank-infantry assaults, causing heavy American casualties. Our old friend Eugene Sledge with K Company, 3d Battalion, 5th Marines, wrote about fighting in this area, it is as follows
“Johnny led us on up through a jumble of rocks on Hill 140. Company K's line was emplaced along a rock rim, and we set up the mortars in a shallow depression about twenty yards behind it. The riflemen and machine gunners in front of us were in among rocks along the rim of Hill 140 facing east toward Walt Ridge and the northern end of the infamous Horseshoe. We had previously attacked that valley from its southern end. From the rim of Hill 140 the rock contours dropped away in a sheer cliff to a canyon below. No one could raise his head above the rim rock without immediately drawing heavy rifle and machine-gun fire. The fighting around the pocket was as deadly as ever, but of a different type from the early days of the campaign. The Japanese fired few artillery or mortar barrages, just a few rounds at a time when assured of inflicting maximum casualties. That they usually did, and then secured the guns to escape detection. Sometimes there was an eerie quiet. We knew they were everywhere in the caves and pillboxes. But there was no firing in our area, only the sound of firing elsewhere. The silence added an element of unreality to the valleys. If we moved past a certain point, the Japanese opened up suddenly with rifle, machine-gun, mortar, and artillery fire. It was like a sudden storm breaking. More often than not we had to pull back, and not a man in the company had seen a live enemy anywhere. They couldn't hope to drive us off by then or to be reinforced themselves. From that point onward, they killed solely for the sake of killing, without hope and without higher purpose. We were fighting in Peleliu's ridges and valleys, in terrain the likes of which most Americans could not even visualize, against an enemy unlike anything most Americans could imagine”.
In response to this setback, Rupertus halted further offensive operations and ordered his forces to maintain pressure on the Japanese stronghold through sustained artillery fire and aerial bombardments. Over the next two days, this relentless bombardment cleared so much foliage and undergrowth that visibility across the ridges improved significantly. This allowed the attacks to resume on October 9, and although no ground was gained initially, Harris’s 2nd Battalion succeeded in securing Wattie, Baldy, and 120 Ridges on October 10. They then pushed south to capture the tactically vital Hill 140. From this position, a Marine howitzer provided critical support to the 5th and 7th Marines as they cleared an area approximately 700 yards long and up to 200 yards east beyond the previous containment lines along West Road. However, on October 14, Dark’s 321st Regiment began moving up to relieve the Marines, as General Geiger had decided to end Marine participation in the Battle of Peleliu.
Just before they were relieved, Eugene Sledge wrote a passage about moving through positions in October, finding numerous dead, stinking in the hot sun. One corpse he found made a significant impact on him, here is the passage.
“As we moved past the defilade, my buddy groaned, “Jesus!” I took a quick glance into the depression and recoiled in revulsion and pity at what I saw. The bodies were badly decomposed and nearly blackened by exposure. This was to be expected of the dead in the tropics, but these Marines had been mutilated hideously by the enemy. One man had been decapitated. His head lay on his chest; his hands had been severed from his wrists and also lay on his chest near his chin. In disbelief I stared at the face as I realized that the Japanese had cut off the dead Marine's penis and stuffed it into his mouth. The corpse next to him had been treated similarly. The third had been butchered, chopped up like a carcass torn by some predatory animal. My emotions solidified into rage and a hatred for the Japanese beyond anything I ever had experienced. From that moment on I never felt the least pity or compassion for them no matter what the circumstances. My comrades would field-strip their packs and pockets for souvenirs and take gold teeth, but I never saw a Marine commit the kind of barbaric mutilation the Japanese committed if they had access to our dead. When we got back to the gun pit, my buddy said, “Sledgehammer, did you see what the Nips did to them bodies? Did you see what them poor guys had in their mouths?” I nodded as he continued, “Christ, I hate them slant-eyed bastards!” “Me too. They're mean as hell,” was all I could say.”
About mid-October, a number of command changes occurred in the Palaus area. On the 12th, for instance, the 1st Marine Division was relieved of all responsibilities other than continuing the fight in the Umurbrogol Pocket. The 321st Infantry took over the defenses along the eastern arm, while the Island Garrison Force assumed responsibility for the area south of the pocket. On the morning of October 12, the command post of the 3rd Amphibious Corps moved ashore and General Geiger, the corps commander, declared that the assault and occupation phase of operations on Peleliu was ended. The exact meaning of this announcement is not clear, especially in relation to Admiral Fort's somewhat similar declaration of September 30, stating that Angaur, Peleliu, Ngesebus, and Kongauru had been captured and occupied. However, General Geiger's announcement seems to have been made in preparation for the 1st Marine Division's imminent departure from the Palaus. The statement also bears relation to the passing of control of operations in the Palaus from the 3rd Fleet and Admiral Halsey (as then represented by Admiral Fort's Western Attack Force headquarters) to the Headquarters, Forward Area Central Pacific (Task Force 57), under Admiral Hoover. On the 13th General Geiger issued orders alerting the 321st Regimental Combat Team to relieve the 1st Marine Division elements still at the Umurbrogol Pocket. The next day, control over all operations in the Palaus passed from Admiral Fort to Admiral Hoover's command. With the relief of the Marines at the Umurbrogol, the remainder of the battered 1st Marine Division then began preparations for leaving the Palaus. At the same time, the 1st Battalion, 323rd Regiment, fresh from operations at Ulithi Atoll, started preparations to relieve Marine units in the southwest corner of the pocket, with the rest of the regiment to follow. Consequently, the Marines prepared to depart from the Palaus, with Dark taking over responsibility for the reduction of Umurbrogol.
Since September 29, the Marines had endured an additional 1,000 casualties, bringing their total to 1,252 killed and 5,274 wounded. In return, they estimated having killed between 850 and 1,000 Japanese soldiers, leaving roughly 1,000 defenders in the shrinking pocket as the 321st moved back in. After a failed local attempt to capture the northernmost peak of the Five Brothers Ridge on October 16, Dark launched a general attack the next day, which resulted in a modest gain of about 125 yards and the neutralization of some caves to the east. On the morning of October 18, the attack resumed, with Dark’s 2nd Battalion successfully capturing three peaks of the Five Brothers, thanks to support from mortars, tanks, and LVT-mounted flamethrowers. However, undeterred by this overwhelming firepower, the Japanese immediately counterattacked and reclaimed the three peaks by nightfall. On the southwest side of the pocket, Nakagawa had also sent infiltrators through tunnels and connecting caves to raid the enemy lines, forcing Geiger to redirect elements of the 7th Marines and 323rd Regiment to address this new southern pocket. After much effort, most of the infiltrators were finally pushed north on October 23, though mopping up in the Southern Pocket wasn't completed until November 3. Meanwhile, on October 19, following a deadly napalm strike, Dark’s 1st Battalion advanced up to 50 yards along the ridges west of Hill 140 with the help of howitzers and much-needed sandbags. The battalion's men, lying prone on the ground, inched their sandbags forward with rifle butts or sticks, laboriously expanding their hold and almost realizing the infantrymen's dream of portable foxholes.
The next day, General Mueller formally assumed command of the Peleliu campaign. Following some reconnaissance and a napalm strike, the 321st resumed its assault on October 21, making significant progress by advancing over 100 yards and capturing the northernmost peak of the Five Brothers. On the subsequent day, Dark launched a coordinated attack with his 2nd Battalion securing the first three Brothers, the reinforced 1st Battalion struggling to breach Death Valley, and the 3rd Battalion sweeping through Mortimer Valley with tank support. After this achievement, while Colonel Watson was bringing the remaining 323rd Regiment to the Umurbrogol area, the only major progress was the capture of the fourth Brother on October 23. Two days later, the 323rd began relieving the weary 321st Regiment. By this time, Dark had lost 146 men killed and 469 wounded on Peleliu. As Watson took over, Nakagawa's forces had been reduced to about 700 effective troops, including those lightly wounded. The pocket's dimensions had also been compressed to an average north-south length of about 600 yards. Fortunately for the defenders, heavy rains, fog, and poor visibility significantly hampered Watson’s operations in the Umurbrogol Pocket from October 26 to November 1. This period was used mainly for mortar barrages, napalm strikes, defense enhancements, and extending sandbag fortifications. Despite this pause, Nakagawa launched near-nightly counterattacks over the six days, primarily targeting the Five Brothers, which mostly resulted in further casualties for the defenders. To understand the eventual reduction of the Umurbrogol Pocket, we will need to shift our focus to the plans and preparations for General MacArthur's grand return to the Philippines.
Previously, General MacArthur, along with Admirals Nimitz and Halsey, decided to abandon the preliminary operations for Mindanao and Yap in favor of a direct assault on Leyte. To be much more frank General MacArthur was having a turf war with Admiral Nimitz. After the Marianas campaign, the endgame of Nimitz island hoping across the Pacific forced the Joint Chiefs of staff to make a choice, to invade the Philippines, or leave it to wither on the vine and instead invade formosa. Admiral King, the joint chiefs of staff, Admiral Leahy and General Hap Arnold all favored the Formosa option. For quite awhile Nimitz got everyone onboard with this plan as Formosa was a logical choice being only 900 kms away from Japan and its seizure would cut off southeast asia from the home islands. With Formosa the Americans could even begin an invasion of southern CHina to aid their allies there and toss plenty of B-29s at the home islands from a much closer location. But then there was the force of nature that was Douglas MacArthur. MacArthur argued Formosa would be “a massive operation, extremely costly in men and shipping, logistically precarious and time consuming.” And he was willing to take his case straight to Washington. In July of 1944 he along with Nimitz went to Honolulu to meet with FDR. MacArthur bitterly protested the meeting, as he knew full well FDR was trying to get re-elected for a fourth term “humiliation of forcing me to leave my command to fly to Honolulu for a political picture taking junket.” So not to be outdone by FDR, MacArthur showboated, by landing early with. He went to a local shop in a limousine he borrowed, and had his staff place a 4 star general insignia upon. He wore khaki trousers a brown leather air force jacket and the cap of a Filipino Field Marshall, going out into public waving at crowds gathering to see the president. When he moved into a cabin to meet with FDR he refused to change into cooler attire stating to FDR , “you haven’t been up there where I came from, and it’s cold up there in the sky.” MacArthur then pretended Nimitz was not in the room and dominated the strategic discussions and attempted at every possible moment to impose his will on the rather ailing and sickly president, whose physical decline had become more apparent. During a private meeting between the two MacArthur said this to FDR “Mr. President, the country has forgiven you for what took place on Bataan. You hope to be re-elected president of the United States, but the nation will never forgive you if you approve a plan which leaves 17 million Christian American subjects to wither in the Philippines under the conqueror’s heel until the peace treaty frees them. You might do it for reasons of strategy or tactics, but politically, it would ruin you”
Rather ironic given it was his responsibility to defend those he was now blackmailing FDR to save. But the truth of the matter was, MacArthur had stolen the American press and American peoples hearts, his grand statement to return to the Philippines was a huge issue. There of course was the other issue, MacArthur could run on the Republican ticket against FDR. Some would allege FDR was bullied into an invasion of the Philippines because of this. To twist FDR’s arm, MacArthur assured him the losses in retaking Luzon would be minimal “Mr. President, my losses would not be heavy, any more than they have been in the past … your good commanders do not turn in heavy losses.” Despite it being a slight against Nimitz, MacArthur’s arguments did twist his wrist. That evening FDR spoke to his doctor Ross McIntire stating this “Give me an aspirin before I go to bed. In fact, give me another aspirin to take in the morning. In all my life nobody ever talked to me the way MacArthur did.” When leaving back on his plane, MacArthur turned to his aide and boasted, “We’ve sold it.” and when he returned to his South West Pacific Area Command HQ in Brisbane, MacArthur informed his staff, “the President has accepted my recommendations and approved the Philippines plan.”
MacArthur was a bit too optimistic, although FDR agreed to invade the Philippines he did not do so without recommendations of his joint chiefs of staff. The Navy was to bear the brunt of furnishing air support in the early stages of the campaign. By arrangement with Admiral Nimitz, the Carrier Task Force from Admiral Halsey's 3rd Fleet was to strike northern Luzon and Okinawa or Formosa, or both, from A Day minus 10 to A minus 7. From A minus 4 through A Day, strikes were to be made on Luzon, the Cebu-Negros area, and the Leyte area in support of the landings. As soon as the Palau air base facilities would permit, shore-based air forces from the Central Pacific were to operate in the Bicol area. The Allied Naval Forces was to furnish carrier aircraft as protection for convoys and naval task forces and, supplemented by aircraft of the 3rd Fleet and the Allied Air Forces, to provide direct air support for the landings. In addition, it was to furnish protective air support and cover by carrier aircraft prior to A Day for the preliminary landings in Leyte Gulf and for the mine sweeping. On September 24, General Kenney issued his order for the Leyte operation and assigned missions to the Allied Air Forces. He designated General Whitehead's 5th Air Force as the Air Assault Force. It was to support the operation by intensified air activities against enemy installations, destroy hostile air and surface forces in the Celebes Sea and assigned areas in the Philippine Archipelago, and provide air defense for existing bases and forces in transit to Leyte within range of its capabilities. It was also to be prepared to establish, on order, land-based air forces on Leyte. The 13th Air Force was to support the missions of the 5th Air Force, while the Royal Australian Air Force Command was to destroy Japanese installations and sources of raw materials in the Netherlands Indies.
Additionally, Halsey’s 3rd Fleet was to be on standby to support the Leyte operation, with the objective of "destroying enemy naval and air forces in or threatening the Philippine Area." Submarines from both the Southwest and Central Pacific Areas would provide support through offensive reconnaissance of likely Japanese routes, maintaining observation and lifeguard services, and offering weather reports and strategic patrols. On the ground, General Krueger’s 6th Army would lead the Leyte assault, taking over the operation after the disbandment of Alamo Force on September 25. With this force moving to the Philippines, General Eichelberger’s 8th Army was assigned garrison duties in New Guinea, New Britain, the Admiralties, and Morotai. For King II, Krueger’s forces included General Sibert’s 10th Corps, consisting of the 1st Cavalry and 24th Infantry Divisions, totaling 53,000 men, and General Hodge’s 24th Corps, comprising the 7th and 96th Divisions, totaling 51,500 men.
The corps originally designated for the canceled Yap operation was reassigned to the 6th Army, replacing the 14th Corps, which was meant to carry out the initial Leyte landings after securing Mindanao. However, the 14th Corps was still in the process of being relieved at Bougainville. To further support the operation, Krueger kept the 32nd and 77th Divisions in reserve, totaling approximately 28,500 troops. Krueger's plan involved an advance team landing Lieutenant-Colonel Henry Mucci's 6th Ranger Battalion on the islands guarding the approaches to Leyte Gulf on October 17. As the Rangers took control of these small islands, Admiral Oldendorf's Fire Support Group would initiate a comprehensive bombardment campaign in preparation for the landings. Minesweepers and underwater demolition teams would also begin clearing natural and man-made obstacles from the gulf. On October 20, Admiral Barbey's Task Force 78 was to transport and land the 10th Corps, while Admiral Wilkinson's Task Force 79 was tasked with landing the 24th Corps. The reinforced 21st Regiment was scheduled to land at 09:30 near Panaon Strait, at the southeastern tip of Leyte, to secure control of the entrance to Sogod Bay. Further north, the 10th Corps was to land two divisions abreast in the Marasbaras and Palo areas at 10:00, while the 24th Corps would simultaneously land two divisions abreast in the Dulag area, about 15 miles to the south. Major-General Verne Mudge’s 1st Cavalry Division was to capture Tacloban and its airfield and secure control of San Juanico Strait, while Major-General Frederick Irving’s 24th Division seized Palo and advanced northwest through the Leyte Valley. The two divisions would then converge on Carigara at the northern end of the valley.
Hodge's strategy involved Major-General James Bradley’s 96th Division landing between Dulag and San Roque to secure a segment of Highway 1 within its operational zone, as well as Catmon Hill and the Dagami-Tanauan area. Since Bradley’s task was relatively easier, the 381st Regiment was designated as Krueger’s floating reserve. At the same time, Major-General Archibald Arnold’s 7th Division was tasked with coming ashore in the Dulag area. One part of this division was to move south to capture the Highway 1 bridge and the Daguitan River crossings at Dao, while the main force advanced along the Dulag-Burauen road to take Burauen and then push on to Dagami. From there, Arnold's troops were expected to be ready to seize Abuyog and Baybay, eliminating enemy forces on the west coast and in southern Leyte. With the successful completion of these objectives, Krueger aimed to break the backbone of Japanese resistance. Consequently, with Leyte Valley and its airfields and base sites secured by the 6th Army, the 10th Corps would then advance south through the Ormoc Valley towards Ormoc, while the 24th Corps would move north from Baybay along the Ormoc Bay coast to link up with Sibert. Meanwhile, General Yamashita relied on General Suzuki’s 35th Army, which consisted of four divisions and two independent mixed brigades dispersed across the central and southern Philippines. Specifically, Leyte was defended by Lieutenant-General Makino Shiro’s 16th Division, experienced veterans of the initial Japanese invasion of the Philippines. Aside from minor forces left on Luzon and Samar, Makino commanded the full combat strength of the 16th Division, supplemented by 4th Air Division ground units, 35th Army service units in the area, and elements of the 36th Naval Guard Unit stationed at Ormoc and Tacloban.
Anticipating that enemy landings would most likely occur in the Dulag-Tarragona-Abuyog sector, Makino strategically positioned the majority of his troops in fortified coastal positions between Abuyog in the south and Palo in the north, with the densest concentration around Dulag. By October, the 16th Division had completed three lines of trenches along the shoreline, but these defenses were weak and inadequately placed. The field positions were old-type long connecting trenches prepared in three echelons. These were difficult to defend and easily discovered from the air since camouflage was lacking. The only effective positions were the cave emplacements for artillery, which had been constructed on Catmon Hill. About 60% of the defenses constructed were completed by the time of the invasion.
In the event of an enemy invasion, Suzuki kept the 30th Division and three battalions of the 102nd Division as a mobile reserve, ready to be deployed to destroy the enemy wherever they landed. This strategy was known as the Suzu Plan: if the enemy landed at Davao, the mobile reserve would reinforce the 100th Division; if they landed on Leyte, the main force of the 30th Division and three battalions of the 102nd Division were to land at Ormoc to support Makino's defenders.
Meanwhile, back in September, Mitscher's fast carriers had conducted several strikes against the Philippines, leading to the near destruction of Japanese air forces and shipping in the region. To prevent air reinforcements to the Philippines, Halsey ordered Admiral Sherman's carrier-based aircraft to launch strikes against enemy aircraft staging areas in the Ryukyus, particularly Okinawa, on October 10. These strikes successfully destroyed an estimated 111 planes and sank or damaged 34 ships. Simultaneously, a cruiser force under Rear Admiral Allan Smith shelled Minami Torishima. The following day, the carriers under Admirals McCain and Davison carried out a feint attack on northern Luzon, sinking two more ships off Aparri.
As the attack on the Ryukyus began, Admiral Toyoda was at Shinchiku in northern Formosa, returning to Tokyo after a command inspection in the Philippines intended to boost morale. Upon learning of the strikes, Toyoda believed that the American carriers in the northern Philippine Sea were vulnerable to his powerful land-based air forces. Over 1,800 aircraft were allocated for Sho in total, but they were widely dispersed across the four operation regions. About one third of them were not battle-ready due to casualties and a lack of parts or trained pilots. When the fighting began, Vice-Admiral Fukudome Shigeru (commander of the 2nd Air Fleet based in the Kyūshū-Okinawa-Formosa district) had approximately 700 planes ready in Formosa and Kyushu. 100 or so aircraft in the Seto Inland Sea was later added to his command. Over the next four days, an additional 690 or so planes flew in from bases in Japan and China.
Toyoda saw this as a prime opportunity to deal a crippling blow to the enemy fleet and disrupt the Allied invasion timeline. Consequently, he decided to risk all available naval air power in a determined effort to destroy Mitscher’s carrier forces, taking personal command of the battle operations in Formosa on October 10.
As anticipated, Halsey planned to launch strong carrier-based strikes against Formosa on October 12 and 13. Mitscher’s four task groups were assigned targets in southern, northern, and central Formosa, as well as the Takao area. Additionally, General LeMay’s first two B-29 strikes of October were scheduled to support the attack, targeting the Okayama aircraft repair and assembly facility in Takao with 170 sorties. Originally set for October 11 and 14, these strikes were postponed to October 14 and 16 due to unfavorable weather forecasts.
After a rapid overnight approach on October 11, Mitscher’s carriers reached their positions off Formosa the next morning. All four task groups completed launch of predawn fighter sweeps by around 06:00 hours. Because the Japanese were on alert, Grumman F6F Hellcat fighters from all four groups were intercepted by enemy aircraft and moderate to intense anti-aircraft fire was universally reported. Air-to-air engagements were fiercest over northern and central Formosa, where aircraft from Rear Admiral Gerald F. Bogan's TG 38.2 and Rear Admiral Frederick C. Sherman's TG 38.3 operated. Sherman's USS Lexington and USS Essex claimed almost 50 enemy aircraft shot down between them. Bogan's task group contained three Essex-class carriers – USS Intrepid, USS Bunker Hill and USS Hancock. Intrepid and Bunker Hill claimed over 50 Japanese aircraft destroyed, making the combined claims for the two groups around 100. Many of Japan's more experienced pilots were killed during the first wave of American air raid. American carrier air groups had suffered minimal personnel losses with nine U.S. aircraft shot down with three pilots subsequently recovered by nearby ships or submarines. These lopsided results were in part due to a lack of experience among Japanese pilots. IJAAS fighters stationed to the north of the Philippines were still in training. The bulk of enemy fighter aircraft reported by U.S. aviators were Japanese Army types, primarily the Nakajima Ki-44 (Allied reporting name "Tojo"), Kawasaki Ki-61 ("Tony") and Nakajima Ki-43 ("Oscar") models. Even though there were some experienced Japanese naval aviators operating at this time, IJNAS Mitsubishi A6M Zero fighter units reconstituted after the Battle of the Philippine Sea were still learning to work together and did not execute the kind of section or division flying that yielded tactical advantage.
By the third strike, the Hellcats had established air dominance over Formosa, with Admirals Bogan and Sherman each claiming over 50 Japanese aircraft destroyed at the cost of nine American planes shot down.
This enabled the Americans to carry out four strikes during the day preceded by a fighter sweep. The Hellcats quickly gained air control over Formosa against the 230 Japanese fighters on the island. By the third strike of the day, the Americans faced no air opposition. A total of 1400 sorties were carried out on this day, sinking or damaging 24 vessels off the Pescadores and Takao.
This led Toyoda to order the activation of the air component of Operation Sho-Go at 10:30 on October 12. Although over 1,900 dispersed aircraft were assigned to Sho-Go, most did not arrive in the forward area for several days. Consequently, Vice-Admiral Fukudome Shigeru's 2nd Air Fleet began preparing up to 800 planes in southern Kyushu for an attack, supported by Admiral Ozawa's newly-reconstituted flying groups from the 3rd and 4th Carrier Divisions. Though the day's remaining carrier strikes by Hellcat fighters, Curtiss SB2C Helldiver dive bombers, and Grumman TBF Avenger torpedo bombers did significant damage to military installations on Formosa, they failed to completely neutralize Japanese air power based on the island. Lead aircraft on 14 October had made photos revealing Navy damage which included four buildings destroyed and nine damaged out of eighty at the assembly plant, and five hangars destroyed at the air base. Many surviving structures would be destroyed by B-29 raids during the later days of the battle, however.
The only Japanese attack that day involved about 45 torpedo bombers, which mistakenly reported two carriers as damaged. Meanwhile, the T Attack Force, a special unit for operations in adverse weather, conducted a strike within a sudden typhoon from 19:00 to 20:20 before landing on Formosan bases. Their efforts were largely ineffective as American ships used smoke screens and evasive maneuvers to avoid damage. Eight Japanese aircraft were shot down by ships' guns during the night, and three Mitsubishi G4M "Betty" bombers were claimed by night fighters from the USS Independence. USS Pritchett suffered damage from friendly fire, but no damage from enemy aircraft was incurred. On October 13, Mitscher's forces resumed strikes against Formosa and the Pescadores with up to 600 aircraft, encountering less opposition but achieving only minor damage due to poor weather. Despite this, Halsey reported the destruction of 520 Japanese aircraft, the sinking of 37 ships, and 74 probable sinkings over the two days.
At dusk, the carriers came under attack from 32 planes of the T Attack Force. Despite Belleau Wood’s combat air patrol shooting down 16 enemy aircraft, six G4M bombers managed to evade the interceptors and launched a series of determined attacks on Davison’s carriers, releasing four torpedoes before all six were eventually downed by shipboard anti-aircraft guns. Fortunately, the torpedoes missed their targets. One torpedo ran just ahead of the USS Franklin, and another ran too deep and passed beneath the carrier. One of the Bettys attempted to crash into Franklin on its way down but glanced off the flight deck and slid over the starboard edge of the ship into the water.
However, McCain’s carriers faced more challenges as eight B6N2 bombers, evading radar by flying low, attacked the group. While six of the bombers were shot down by anti-aircraft fire, one successfully torpedoed the cruiser Canberra, killing 23 crew members and causing severe damage. The torpedo struck the cruiser in a vulnerable spot—under the main armor belt between both firerooms. The ship lost all power, laying just 90NM off Formosa. As a result, Halsey organized a unit to tow Canberra to safety, necessitating an additional day of protection for the damaged cruiser. On October 14, Mitscher launched early morning fighter sweeps to suppress enemy air power over Luzon and Formosa, while the newly-formed unit escorted Canberra. Japanese reports claimed two carriers were sunk and one was burning, leading Toyoda to believe the enemy retreating east had been severely damaged. Consequently, Fukudome ordered his full strength of 450 planes to launch from southern Kyushu, and Vice-Admiral Shima Kiyoshide’s 2nd Striking Force was deployed to sweep the waters east of Formosa. However, before the Japanese could counterattack, 130 B-29s from Chengdu attacked Formosa in the afternoon, with 104 bombers successfully dropping about 650 tons of bombs on Okayama and 13 hitting secondary targets. A dozen planes made emergency landings at friendly fields in China, one crashed near Changteh whence its crew walked out, and one was listed as missing. This was a cheap price to pay for very severe damage done to Okayama installation.
At 15:25, Fukudome’s initial wave of 124 planes attacked Bogan’s carriers. A formation of 25 Yokosuka D4Y "Judy" dive bombers, using cloud cover to evade detection, was intercepted by the group's combat air patrol. Only a few Japanese planes made it past the American fighters. The surviving bombers were able to put two bombs in the vicinity of the Hancock, and one hit the forward port side gun tube without detonating on impact. No serious damage was inflicted by this attack. At around 17:00 a large formation of enemies showed up on radar headed towards TG 38.3. As before, a great many of these were shot down by combat air patrol. The surviving enemy planes flew down to the water level to evade further radar detection. These planes – torpedo bombers and fighters – successfully ambushed the formation just minutes later. Evasive maneuvers, squall weather, and poor fighter cover on the part of the Japanese helped TG 38.3 escape without suffering any significant damage.
The only bright spot for the Japanese was another twilight attack by the T Force by 52 aircraft against TG 38.1. Four Jills broke through to attack light cruiser Houston. Three were shot down, but the last succeeded in placing a torpedo in another vulnerable spot that flooded the engineering spaces and caused all power to be lost. As a result, Halsey was left needing to tow two cruisers to safety.

By hook or by crook, General MacArthur bullied FDR into allowing an invasion of the Philippines. To soften up the new targets, strikes were unleashed against Luzon, Formosa and Okinawa. Despite a strong Japanese defense, American air superiority was achieved through aggressive carrier strikes, leading to the destruction of numerous Japanese aircraft and ships.

- 150 - Pacific War Podcast - Fall of Angaur 3 - October 10 - , 1944
1 10月· The Pacific War - week by week
Last time we spoke about the ongoing battles of Peleliu, Angular and Operation Ichi-Go. On September 23, Colonel Venable's regiment struggled to breach Lake Salome's defenses, leading to tactical changes and propaganda attempts to force Japanese surrender, which ultimately failed. The American command underestimated Japanese resolve, resulting in heavy bombardments and a strategic advance. By September 26, American forces had divided Peleliu and isolated Japanese defenders, facing fierce resistance but making significant progress. On September 27, 1944, Company F secured two ridges in Peleliu but struggled with Japanese forces entrenched in caves, halting progress. Despite controlling the northern shore, Marines faced persistent underground resistance from skilled Japanese miners. Meanwhile, the 5th Marines captured Hill 3, Ngesebus Island, and Radar Hill. In October, Japanese offensives continued against minimal resistance.
This episode is the Japanese Triumph in China

In our previous episode, General Mueller’s infantry on Angaur had driven Major Goto’s isolated forces into the Romauldo Pocket by October 1. After this victory, it was decided to shift away from costly full-scale infantry assaults. Instead, tanks, mortars, and artillery were deployed to target the remaining enemy positions directly. On 6 October artillery and mortars undertook an especially heavy bombardment. From 0700 to 1030, 155-mm. howitzers fired at especially chosen targets, including a suspected Japanese observation post, while 105-mm. howitzers, 4.2-inch mortars, 81-mm. mortars, and 60-mm. mortars laid concentrations on the flanks and rear of the remaining Japanese-held area to prevent any Japanese from escaping. At 1030 the artillery and mortars switched to smoke shells to blanket the Japanese area and at 1035 these weapons ceased fire.
Following the bombardment, two companies were dispatched to feint attacks on the Japanese flanks, aiming to force them out of their fortified positions. The defenders, deceived by the ruse, were then subjected to another intense artillery and mortar barrage, which inflicted significant casualties. Additionally, in the afternoon, a major concrete and steel emplacement, likely serving as Goto's command post, was uncovered and destroyed by direct fire. With the enemy defenses considerably weakened, infantry operations resumed, focusing on sniper teams, small patrols, ambushes, and booby traps to encircle the remaining Japanese forces and cut off their supply and escape routes. Over the next few days, the Americans also rescued 183 captive natives during the final stages of their assault.
The Japanese had under their control in the final pocket a number of Angaur natives, three of whom had managed to make their way into the 322nd Regiment lines after a surrender broadcast on October 1. These related stories of hardships suffered in caves where the Japanese had kept them closely guarded and also told the 322nd that more natives were being held in the northwest pocket. First attempts by native volunteers to lead some of the others out were unsuccessful; but on October 8,137 more natives made their way out of the pocket to an area where elements of Company B, 306th Engineers, were working. The next day, three native volunteers led 90 more out of the pocket. About 1/5 of the total of 183 natives rescued from the Japanese needed extensive medical attention and all the rest were suffering from malnutrition. The healthier ones rebuilt their own village and some were ultimately used as labor on various projects at Angaur.
On October 13, a coordinated attack was launched, with the 1st Battalion advancing from the west and the 2nd Battalion pushing from the north and northeast. Despite fierce resistance, by October 18 the Americans had successfully compressed the remaining Japanese into a pocket approximately 100 yards long and 50 yards wide. The following night, Major Goto was killed, and by October 21, the last pockets of resistance were eliminated.
The engagement ended two days later when the Americans realized they had eliminated nearly all the Japanese troops, with only a few stragglers remaining. By the conclusion of the Battle of Angaur, approximately 1,300 Japanese soldiers had been killed, and 45 were captured. The Americans, on the other hand, suffered 264 men killed and 1,355 wounded, primarily from the 322nd Regiment. To be more specific the 321st Infantry's part in the operation had cost that regiment 26 men killed and 135 wounded. The 322d Infantry, which fought longer and against stiffer opposition, lost 211 men killed and 772 wounded.
Despite the heavy losses, capturing Angaur proved crucial in securing the Palaus and removing the island group as a threat to Allied lines of communication across the western Pacific toward the Philippines. Airdrome construction on Angaur was begun on 20 September, F plus 3, by the 1884th and 1887th Engineer Aviation Battalions. The first plane, a C-47, landed on the field on F plus 28, 15 October. Four days later two 6,000-foot landing strips were completed and work on taxiways, gasoline storage, and other air-base installations was well along. Air-base construction on Angaur presented difficult problems. There was available no conveniently located Japanese airfield which the Allies could repair, improve, and expand. Instead, the work had to begin at the beginning. Jungle had to be cut away, swamps filled, and rough terrain leveled. There was no hope that an airstrip could be prepared in three or four days as had been the case on many other islands in the Pacific. The completion of two 6,000-foot runways by 19 October, F plus 32, represented a considerable accomplishment. In defending Angaur, the Japanese lost a well-equipped, highly trained, and well-led infantry battalion. While this force might have been more effectively deployed elsewhere in the Palaus, it succeeded in its mission of delaying the American advance.
Meanwhile, General Ishii of the 32nd Division decided to reinforce the limited Japanese presence in Morotai to hinder the development of an enemy airbase capable of supporting an assault on the Philippines. Consequently, three temporary raiding detachments from the 10th Expeditionary Unit and the 211th and 212th Regiments were formed, with the 210th Regiment preparing a battalion as a follow-up force. On the night of September 26, Ishii’s reinforcements began their movement to Morotai in barges, with two detachments successfully landing near Tilai and the other near Cape Posiposi despite interference from Allied PT boats. Enemy patrols around the island's perimeter blocked the use of coastal tracks, forcing the reinforcements to navigate through dense jungle.
As the concealed Japanese raiders made their way toward Major Kawashima’s main force in the Pilowo-Sabatai River area, the 3rd Battalion of the 210th Regiment landed in the Boesoboeso sector on October 9. The raiding detachments finally joined up with the 2nd Provisional Raiding Unit on October 20. Without waiting for the 210th battalion, Kawashima initiated a series of new infiltration raids, some of which reached the airfield itself. Although these reinforcements created some disruptions by harassing Allied outposts, they did not significantly impact the situation at Morotai. This was due to high disease rates among the reinforcements and the inability to deliver enough supplies through the Allied air and naval blockade. General Anami decided more decisive action was needed to prevent the enemy from utilizing their airbase effectively. He instructed Ishii to deploy as much force as possible to Morotai to destroy the enemy. In response, Ishii planned to send additional reinforcements, including the main forces of the 210th and 211th Regiments and the 18th Shipping Engineers. By November 16, approximately 1,900 troops successfully landed south of Wadjaboela, with Colonel Kisou Ouchi taking command of all Japanese forces on Morotai. Raiding activities intensified in December, but with the new year, American torpedo boats further tightened the blockade, making it impossible for the 32nd Division to supply the ammunition and rations needed for a major offensive. Unable to dislodge the enemy from Morotai, the Japanese eventually had to withdraw to the center of the island, where they remained until the end of the war.
The most notable Japanese response to the Allied landing was a series of frequent but mostly ineffective air raids. The first raid occurred on September 16 when a solitary enemy aircraft dropped three bombs on the Red Beach area, causing no damage. Between September 15, 1944, and February 1, 1945, General Sudo’s 7th Air Division conducted 82 raids on Morotai, involving 179 sorties. The initial 54 raids caused minimal damage, with only twelve Allied soldiers wounded by October 4. However, the later raids resulted in 42 Allied aircraft destroyed, 33 damaged, 19 men killed, and 99 wounded. Despite these efforts, Morotai was successfully developed into a crucial base for the return to the Philippines. In Bougainville, with General Griswold’s 14th Corps initially slated for the Leyte invasion, efforts were made to replace it with the Australian 2nd Corps. Although Griswold’s corps would not participate in the October 20 operation, advance elements of General Savige’s headquarters landed on October 6 to facilitate the transition. By mid-November, the 7th Brigade had relieved the 129th and 145th Regiments, and on November 22, Savige officially took command of Allied operations on Bougainville. By December 12, the replacement of American frontline troops by Australians was complete, and with only a few service personnel remaining, all American troops had departed by February 1, 1945.
Despite having 30,000 men—though always short on heavy equipment and shipping—Savige's forces were considered sufficient to continue monitoring the Japanese and defending the perimeter around the airfields from any potential counterattacks. However, General Blamey disagreed with this approach and preferred a more aggressive strategy. He wanted his troops to actively seek out and destroy the enemy by patrolling deep into Japanese-held territory, targeting supply areas and bases to starve and eventually annihilate the Japanese garrisons. This shift in strategy signaled the start of a new offensive phase in the Bougainville Campaign. At the same time, attention shifts to North Burma, where the Allied campaign continued after the victories at Myitkyina and Mogaung. However, the strained relationship between General Stilwell and Chiang Kai-Shek was approaching its breaking point. Confronted with the impending loss of Guilin, Stilwell persuaded President Roosevelt to issue an ultimatum to Chiang, threatening to cut off American aid to China unless Stilwell was given full command of all forces in China. Chiang, perceiving this as an attempt to dominate China, countered by demanding Stilwell's immediate replacement and welcoming any other qualified American general. As a result, on October 19, Stilwell was recalled and replaced by Major-General Albert Wedemeyer by the end of the month. The China-Burma-India Theater was then reorganized: Lieutenant-General Daniel Sultan took over the India-Burma Theater, while Wedemeyer assumed command of the newly established China Theater. However, Wedemeyer would only serve as chief of staff to Chiang, not taking effective command of the Chinese forces.
Thus, no American officer would be held accountable for the loss of eastern China. Nonetheless, this represented another significant diplomatic victory for Chiang Kai-Shek, though it would be his last for many years. However, it also marked the end of his relationship with Roosevelt, who had previously championed China's and the Generalissimo's interests. Meanwhile, upon taking command, Wedemeyer faced open dissent among the Chinese Nationalists, with local commanders in eastern China on the verge of insurrection against Chiang’s regime, as he had refused to supply arms to those defending against the Japanese advance in Operation Ichi-Go.
There were many detailed reports that the east China commanders bitterly resented the Generalissimo's failure to support them. When Hengyang fell on August 8, Chinese claiming to be emissaries of these men presented to American authority a plan for a separatist regime and pleaded for American support. Unknown to the Americans, Chinese making identical representations had been negotiating with the Japanese since the winter of 1943-44. Intelligence reports were received at US headquarters to the effect that the Generalissimo's attitude toward the east China campaign reflected an understanding between him and the Japanese under which they would leave him undisturbed in southwest China if he in turn would not interfere while they took the airfields that presented so obvious a menace to the Japanese homeland. In 1951 a group of senior Japanese staff officers of China Expeditionary Army were interrogated on the question of Sino-Japanese relations in 1944. They denied that there had been any understanding between the Japanese and the Chinese Central Government. Two of them, Lt. Cols. Yoshimasa Okada and Yoshio Fukuyama, stated that an agreement was reached between the Japanese 23rd Army at Canton and the local Chinese commander, General Yu Hanmou, in February 1944 under which General Yu agreed not to disturb Canton when the Japanese marched north from it. Yu kept his word, according to Okada, even though the Generalissimo was ordering him to attack Canton. The Japanese officers agreed among themselves that there had been extensive contact with dissident Nationalist commanders in southeast China, and stated that through many channels they had sought to inform the Chinese that the east China drive offered no threat to them, but only to the US airfields.
One of Wedemeyer’s key objectives was to prevent China from fragmenting into warring factions. Additionally, he observed that air transport was delivering supplies to China at unprecedented rates, with 35,131 tons arriving in October 1944—four times the amount sent to support Stilwell in October 1943. The strength of the Allied forces in northern Burma and the weakened state of the Japanese meant that time was on Wedemeyer’s side; each day China remained an active belligerent bolstered the prospect of significant American supplies soon being available. Consequently, his mission involved continuing support for General Chennault’s 14th Air Force, General LeMay’s 20th Bomber Command, and air transport over the Hump; further training and advising the Y-Force in Yunnan and the Z-Force in eastern China; and assisting the Generalissimo with military operations against the Japanese.
Speaking of Chennault's 14th air force, by November 1944, they now had an average strength of 398 fighters, 97 medium bombers, and 47 heavy bombers. In that same month the Fourteenth received 13,578 tons of supplies flown in over the Hump, of which 9,357 tons were gas and oil. From the Kunming airfields, the China Wing of the ATC flew these supplies to Chennault's forward fields, this intratheater transport being of course a charge on Hump tonnage. The apparent crisis in east China made it seem advisable to use all available Chinese trucks for concentrating the Chinese for the defense of Kunming; the quartermaster truck companies of the SOS were not by themselves enough to support the Fourteenth Air Force. These resources of air power, unimpressive in contrast to what Allied commanders had in Europe or the Pacific, but a good deal more than the Japanese had in China, were divided among two composite wings--the 68th and 69th--the 312th Fighter Wing, the Chinese-American Composite Wing (CACW), and the 308th Bombardment Group (H). An example of Chennault's flexibility, the 68th Wing had three fighter squadrons assigned, with bombers attached as the mission required. The 69th had four fighter squadrons and three medium squadrons. With headquarters at Kunming, it was shifting its attention from the campaign in Burma to the defense of Kunming against a Japanese attack from the south or southeast. The Chinese-American Composite Wing, headquarters at Peishiyi, had two fighter groups and one bombardment group. The 312th had two fighter groups (50 P-47's, 60 P-51's, and 6 P-61's), a total of five squadrons, protecting the B-29 fields at Cheng-tu.
After the air effort and the attempts to move tonnage to the airfields and to the troops, the remaining US project in China was liaison with and training and observation of Chinese troops. On the Salween front, liaison and technical advice was given in the forward areas, while troop training continued in the rear. In east China, the reluctance of the Chinese to attempt a stand after Hengyang's fall on August 8 led to the withdrawal of almost all the Americans who had tried since January 1, 1944 to train a second 30 Divisions in east China. The so-called Z-Force Operations Staff that remained comprised an observer group with the headquarters of the Chinese 9th War Area and a liaison team of 28 under Col. Harwood C. Bowman in the city of Liuchow. This handful of Americans, in the first months of Wedemeyer's command, sought to give technical aid to the Chinese defenders of Guangxi while sending a flow of information back to theater headquarters in Chongqing. They provided air-ground liaison, supervised demolitions, helped distribute the 500 tons of munitions flown into east China in late October 1944, and helped with administrative and logistical matters. The remaining 625 men of Z-FOS, including the headquarters, were in Kunming, their future mission dependent on Wedemeyer's estimate of the situation.
While these events were unfolding, Allied forces in northern Burma were preparing to launch an offensive with six divisions to eliminate the remaining Japanese presence in the region and establish a new supply route to China. Following the capture of Myitkyina and Mogaung, efforts were underway to organize two new Chinese armies, while experienced Chinese divisions continued their rigorous training in anticipation of resuming their advance southward. As the new commander of the Northern Combat Area Command and the Chinese Army in India, Sultan had the New First Army, under General Sun Liren, included the 30th and 38th Divisions. The 38th Division had been engaged since 30 October 1943, and had previously taken a creditable part in the First Burma Campaign of 1942. The division had been trained, re-equipped, and brought up to strength at Ramgarh Training Center in Bihar Province, India. Its sister division, the 30th, was also Ramgarh-trained. Its 88th and 89th Regiments had fought at Myitkyina. There was also New Sixth Army consisting of the 14th, 22nd, and 50th Divisions, commanded by General Liao Yaoxiang. The 22nd Division had fought in the First Burma Campaign, then been rebuilt at Ramgarh. It had been in action since January 1944. Lastly there was General Festing’s 36th Division, and the recently-formed 5332nd Provisional Brigade at his disposal.
Current plans called for brigading the 1st Chinese Separate Infantry Regiment, which had been trained at Ramgarh in long-range penetration tactics, with two American regiments, the 475th Infantry and the 124th Cavalry. The combined unit would be the equivalent of a division, but would have the designation 5332d Brigade (Provisional). To carry out the project, the 5332d Brigade (Provisional), known later as MARS Task Force, was activated 26 July 1944. Brig. Gen. Thomas S. Arms assumed command the same day. The activating order provided for most of the brigade's subordinate units to be attached to it as they arrived in India or were activated--as of 26 July the brigade was still very much in the preparatory stage. Thus, the 475th Infantry Regiment (Long Range Penetration Regiment, Special), Lt. Col. William L. Osborne, was not activated until 5 August 1944. It included many survivors of the original American experiment in long-range penetration tactics--GALAHAD, or "Merrill's Marauders." Its companion regiment, the 124th Cavalry (Texas National Guard), Col. Milo H. Matteson, arrived in India on 30 August 1944. It did not reach the brigade's training area until 27 October. Also attached were the 612th Field Artillery Battalion (Pack), Maj. John W. Read, and six quartermaster pack troops. In mid-August 1944 the training area which had been set up about ten miles north of Myitkyina on the west bank of the Irrawaddy began receiving members of the 475th Infantry Regiment. The area was designated Camp Robert W. Landis in honor of the first member of GALAHAD to be killed in action. Unit after unit started moving into Camp Landis as the 5332d began to put on flesh and assume the likeness of a pair of regimental combat teams. Another battalion of pack artillery, the 613th under Lt. Col. James F. Donovan, the 18th Veterinary Evacuation Hospital, the 44th Portable Surgical Hospital, the 1st Chinese Separate Infantry Regiment, Col. Lin Kuan-hsiang, arrived during the fall.
Unfortunately, after overseeing the 5332nd’s organization and training, Arms was injured in a motor accident and was succeeded by Brigadier-General John Willey on October 31. In support of Operation Capital, it was agreed that Sultan’s forces would advance through the Katha-Bhamo area towards Kunchaung, Sikaw, and Namhkam in mid-October, followed by a southern advance to the Mogok-Mongmit-Lashio line in coordination with General Slim’s push towards Mandalay. Sultan planned a three-pronged attack south from Myitkyina into Japanese-held territory in northern Burma. The British 36th Division and the Chinese 50th Division would advance south along the Railway Corridor to secure the Katha-Indaw area; the Chinese 22nd Division would move southeast to capture the Broadway airstrip northeast of Katha and establish a bridgehead over the Irrawaddy at Shwegu; and the Chinese 38th Division, followed by the 30th Division, would move south from Mogaung to secure the Bhamo-Mansi area.
By the end of August, Festing’s forces had followed the 53rd Division to Pinbaw, then advanced cautiously until they secured Nanma in September. The British moved out on 15 October. At first, contact was light, but by the time they reached Mawlu on 31 October Japanese posts were stronger and closer together and their artillery and mortar fire was progressively heavier. However, at Mawlu the 36th was eighty miles south of Mogaung and very near the great bend of the Irrawaddy which was the goal for 15 December. The Japanese stiffened at Mawlu, and the 1st Battalion, Royal Scots Fusiliers, met artillery, mortar, and machine gun fire that took thirteen casualties. By evening the town was occupied. Road conditions were very bad, for the ground was still wet, and vehicles had trouble moving. After occupying Mawlu the division paused until 9 November. There were brushes with Japanese, snipings, patrol actions, but no heavy fighting. Festing used the lull to bring up the 72d Brigade, and so make his advance one of brigades in line, with the 72d on the east, the 29th on the west. The 72d would make the main effort.
Moving down a dry-weather road parallel to the railway tracks, elements of the 72d Brigade on 10 November met stubborn resistance a few miles northwest of a railway station called Pinwe. It came from a cluster of bunkers, which together with heavy artillery fire and the identification of Japanese from a number of units all pointed to one conclusion for the 36th--it had met the Japanese main line of resistance in this area centering on Pinwe. The Pinwe area was well adapted to defense. Farther north the 36th had fought its way over rice fields, but here the bush made an impenetrable screen on either side of the jungle tracks. Flanking movements were so difficult that they were judged to be impossible. Frontal attacks after artillery and air preparations became the order of the day. The Japanese lines at Pinwe were held by the 119th Regiment, 53d Division. Pinwe was the hardest fighting the 53d had encountered, and the 119th received a diploma of merit for its work there. At night their infiltration parties harassed the British rear areas and sought to destroy their artillery. On one occasion, they thrust so deftly into the British positions as to cut off two companies of infantry, which had to be withdrawn at night. The fighting resolved itself into British attempts at prying the Japanese out of their strongpoints, while maintaining a close guard against Japanese raiding parties. In these days the 72d Infantry Brigade, which had been trying to force its way over the stream covering the principal Japanese positions, took heavy casualties and had to be relieved by the 29th Infantry Brigade. On 25 November the British did put a company across the stream, but found they could not reinforce or supply it. The 53d Division was also ordered to execute limited but bold attacks to its front. To relieve the pressure on the 53d Division, the 15th Division was directed to attack the right flank and rear of the enemy 36th Division along the Meza River. Although the attacks of the 15th Division and the counterattacks of the 53d failed to destroy the enemy, they were successful in checking the offensive of the 36th and enabled the 53d Division to hold the line for approximately three weeks. The order to the 53d showed the DiVision commanders the caliber and determination of the new Army commander and the 53d's success in holding bolstered the sagging combat spirit of the entire 15th Army. Pressure on the 53d Division increased as the weeks went by; and when enemy elements infiltrated into the gap between the 53d and 15th Divisions in late November, the 15th Army finally ordered the 53d to withdraw to Katha and the sector north of Tigyaing. The 15th Division was ordered to withdraw its right wing to maintain contact with the revised battle line of the 53d Division. The 15th Army finally issued orders to the 53d and 15th Divisions directing the commencement of the withdrawal movement to the Irrawaddy River line on 1 December. The 33d Division was directed to withdraw on 4 December, giving the Division additional time for disposal of munitions in its area. From positions in the Kamaing area, far behind the outposts held by the 36th Division in the Railway Corridor, the 22d began its march on 15 October. It was to move southeast toward Mogaung, but bypassing the town to save ten miles, then toward Pinbaw, then Hopin. As the march got under way it appeared that the long rest after combat had left troops and animals in poor condition. The troops were traveling as light as possible, but fatigue was evident when after three days the division reached Hopin. Predawn departures were ordered to keep to a minimum the time spent marching under the full sun, and a day of rest was spent at Hopin. At Hopin the division turned east, to take a route that would sorely test the marching powers of its troops, for the chosen trail led over the ridge that marked the eastern boundary of the Railway Corridor, down into a plain formed by a tributary of the Irrawaddy, where the old Chindit airstrip BROADWAY was located, and up again over a hill mass overlooking the Irrawaddy valley. On 26 October the division reached the airstrip, twenty-seven miles southeast of Hopin. General Liao Yueh-shang, commanding the New Sixth Army, of which the 22d Division was part, flew in to BROADWAY, and gave the division detailed orders for the final move to the Irrawaddy. The division was formed into two columns. On the west, the 64th Regiment was directed to take Shwegugale, which lay on the south bank downstream from Shwegu. The 65th and 66th were to move off as one column, then to split into combat teams just north of the Irrawaddy and cross on a broad front. Kachin irregulars and patrols reported there were no Japanese ahead, and after a three-day rest the division resumed its advance. On 3 November the division occupied the north bank of the Irrawaddy without opposition. The troops rested while commanders studied maps and waited for rubber boats and outboard motors to be airdropped. Three days later the 64th Regiment crossed the Irrawaddy and took Shwegugale against light opposition. Next day the 65th Regiment took Shwegu, and the division had its first objectives. Meanwhile, after the unsuccessful Dan offensive, General Honda reorganized the 33rd Army. The 56th Division resumed defending Longling and Mangshi, while the 18th Division took over the defense of Namhkam. Although the Yoshida Force and the Bhamo Garrison remained with the 33rd Army, the 2nd Division was reassigned to the area army and began relocating to the Pyinmana-Toungoo area by the end of October to be available for operations in central Burma.
Unbeknownst to Honda, he was soon to encounter the full force of Sultan's renewed offensive. Major-General Li Hong’s 38th Division had departed from Myitkyina on October 15, advancing cautiously along the road to Bhamo with minimal contact until October 28. On that date, they encountered Japanese patrols two miles north of the Taping River, which were quickly dispatched. At Myothit was the Japanese outpost line of resistance; the Chinese patrols speedily found that the Japanese meant to defend it. Strong Japanese positions were seen on the south bank, and the commander of the 38th Division, General Li Huang, saw that he would have to force a defended river line unless he could turn the Japanese position. General Li decided to use the 112th and 114th Regiments, which had been the main body of the 38th, as an enveloping force. Since they were some seven miles to the north the 112th and 114th were out of contact with the Japanese and well placed to make a wide swing to the east. The two regiments began their march through the hills, while the 113th made a show of activity around Myothit to keep the Japanese attention focused there. Once again envelopment proved its worth. The Japanese were too few to defend a long line, and the enveloping force was able to cross the Taping at an unguarded bridge upstream, go around the right end of the Japanese outpost line of resistance, and emerge on the Bhamo plain on 10 November. Pressing on west toward Bhamo, the enveloping force met a strong entrenched Japanese force at Momauk, which is eight miles east of Bhamo and is the point at which the Myitkyina-Bhamo road swings to the west for the last stretch into Bhamo. Here there was savage fighting between the 114th Regiment and the Japanese defenders. Heavily outnumbered, the Japanese outpost at Momauk was driven into the main defenses at Bhamo. The appearance of its survivors, some without rifles, others without shoes, depressed the Bhamo garrison.
Hara’s forces endured significant losses as they conducted a delaying action at Momauk, with the remaining reconnaissance units joining the defense of Bhamo by November 16. Meanwhile, the 113th Regiment moved west along the south bank of the Taping River and approached Bhamo from the north. However, instead of directly attacking the town, the 113th Regiment repositioned south and southeast of Bhamo. Concurrently, the 114th Regiment advanced west from Momauk to encircle the town from the north, creating a loose encirclement around the Japanese outposts in the Bhamo suburbs. This maneuver allowed the 112th Regiment to bypass the confrontation entirely and continue south towards Namhkam. By early November, Japanese patrols had also detected the presence of the 22nd Division in the region between Bhamo and Katha, apparently moving towards Mandalay. Fearing that this force might sever the Mandalay-Lashio rail line by advancing through Mongmit, Honda’s staff decided to keep the 55th Regiment stationed at Namhkam and reassign the rest of General Naka’s 18th Division to Mongmit to prevent the effective separation of the 15th and 33rd Armies.
While the 64th Regiment remained to secure the crossing area, the 22nd Division advanced towards Man Tha along the main road south from the Japanese stronghold of Bhamo, which was captured without incident on November 14. Continuing along the Bhamo-Myitson road, the Si-u area was secured by late November, with Colonel Ernest Easterbrook’s 475th Regiment also moving there after bypassing Bhamo successfully. Meanwhile, after a period of recovery due to heavy losses in September, General Wei’s Y-Force was preparing to resume its Salween offensive. On October 29, Lieutenant-General Huang Jie assaulted Longling, defended by the 146th Regiment's main force with artillery support up to 1,700 rounds and 30-40 air sorties per day carried out by 37 P-40s of the 14th Air Force.
Elements of the 200th Division attacked from the south and west, targeting positions behind Colonel Imaoka’s defenses, while two divisions of the 71st Army exerted heavy pressure from the north. With many positions being devastated and numerous defenders killed or wounded, General Matsuyama ordered the 146th to retreat from Longling to Mangshi on November 3. Although the Japanese managed a midnight withdrawal, the Chinese succeeded in capturing their main objective. The Japanese respite, however, unsettled the Americans, who promptly urged Chiang to continue the offensive. Following the Generalissimo’s orders to advance on November 9, Wei directed the newly arrived 53rd Army through the hills north of the Burma Road to Chefang, while the 2nd and 6th Armies moved south towards Mangshi, and the 71st Army proceeded down the road itself.
Against the expected offensive, the 56th Division consolidated its defense around Mangshih with eight infantry and two artillery battalions on an established defense perimeter. The Yoshida Force, which was under the direct command of the Army at Wanting, was assigned the missions of protecting the rear of the 56th Division with its main force in the area north of Chefang and the 3d Battal- ion in the Menka area. At the same time, the 3d Battalion of the 146th Infantry Regiment was moved from Mangshih to join the Yoshida Force. A detachment of about 100 replacement troops was assigned to hold Chefang Pass. Although the 56th Division continued to be optimistic about its chances of holding against the expected Chinese attack, Army Headquarters took a less hopeful view. The Division was ordered to conduct a flexible holding operation north of Wanting and not cling too tenaciously to Mangshih.
After a strong Chinese offensive on November 19, and following Colonel Tsuji's insistence, Matsuyama had no choice but to withdraw during the night to the Chefang Pass. General Matsuyama was strongly in favor of conducting a holding action in the Mangshi area and merely directed a partial withdrawal of his forces to be effected on November 22, 23 and 24. Col. Tsuji, of the 33rd Army headquarters, was present at the 56th Division headquarters and warned the chief of staff against over-optimism. Tsuji stressed the point that, once the withdrawal had been decided upon, the Division should withdraw simultaneously from the entire line to the south of Chefang Pass, preferably on the eve of the general attack or on the following night, at the latest. However, Col. Kawamichi, the Division chief of staff, would not change the order because it had already been passed down to the subordinate units. Subsequently, following an inspection of the front lines and an observation of enemy activity on the 18th, Tsuji came to the conclusion that the enemy would launch a general attack at dawn on the 19th or early on the 20th. He bluntly advised General Matsuyama to change his division order and at his insistence the order was changed to a withdrawal at midnight on November 19 to Chefang Pass. At dawn of the 19th, the Chinese launched a heavy attack in an attempt to envelop the entire line, just as Tsuji had predicted. All frontline units held in their prepared positions and inflicted heavy losses. Throughout the day they were able to check the enemy, but with the tremendous forces arrayed against the Division it is probable that many of the positions would have been overrun the following day. The Division, however, succeeded in withdrawing from the entire line at midnight on November 19.As a result, the strategic Mangshi airfield fell to Wei, enabling him to land supplies rather than relying solely on airdrops.

24 9月· The Pacific War - week by week
Last time we spoke about the battles for Peleliu and Angaur. Following the amphibious assaults on Peleliu and Anguar, US Marines under General Rupertus intensified their offensive. On September 17, Colonel Hanneken’s 7th Marines advanced in Peleliu's southern sector, as the 1st and 5th Marines pushed north, confronting the fortified Umurbrogol Mountains, where Colonel Nakagawa’s defenses stalled their progress. Despite reaching key positions by mid-morning, intense Japanese counterattacks continued, causing heavy casualties. On September 18, the 7th Marines, aided by armor, resumed their slow advance, securing the southern part of Peleliu by day's end. Meanwhile, the 1st and 5th Marines faced brutal combat in the central ridges, suffering significant losses. By September 21, the capture of nearby Ulithi Atoll provided a strategic base for future operations. Despite securing important positions, the Marines encountered severe resistance in the Umurbrogol Mountains, leading to high casualties and necessitating reinforcements. By September 23, the Americans secured footholds on Peleliu and Anguar, yet fierce fighting persisted in Nakagawa’s fortified positions.

This week we are picking up back over on Peleliu and Anguar where the Japanese are still providing stiff resistance. On September 23, Colonel Venable’s 322nd Regiment had made little progress breaking into the Lake Salome bowl. With their commanding officer severely injured, a change in tactics was imminent. On the morning of September 24, propaganda broadcasts over a public address system were used to try and persuade the remaining Japanese to surrender. However, only two Japanese soldiers surrendered, reporting that over 300 defenders remained in the bowl under Major Goto. This accurate estimate was disregarded by the American command, who believed only about 150 defenders remained. Following this failed attempt, all available artillery bombarded the bowl in preparation for an attack from the north, altering the appearance of the bowl's interior and rims to aid the upcoming assault. Back at Peleliu, after heavy bombardment, Colonel Dark’s 321st Regiment resumed its advance north along the coast on September 24, despite continued harassment from Japanese fire from the central ridges. By noon, they had secured the trail-road junction south of Garekoru. Some troops explored the trail to the east, encountering heavy resistance, while Company G advanced rapidly north through Garekoru, reaching the O-4 Line. Behind them, Dark’s 3rd Battalion and Colonel Hanneken’s 3rd Battalion also pushed northwards. Further east, the 7th Marines pressed against Colonel Nakagawa’s main defenses on the Umurbrogol Mountains. By nightfall, having successfully resisted Japanese counterattacks on O-4, General Rupertus’ northward drive had proven to be a significant success.
He next planned to cut across the island on September 25 through the eastern trail to completely isolate the Japanese forces in the Umurbrogol ridges. At 07:00, Dark’s troops began moving eastward, with Company E successfully reaching the edge of East Road against light opposition. They halted in front of Hill B, which dominated the eastern area. However, the 3rd Battalion encountered heavier resistance from pillboxes and emplacements protected by steep walls and sheer cliffs guarding the northern approaches to the Umurbrogol defense system, making little progress. Meanwhile, to the north, a strong tank-infantry patrol advanced about 1,200 yards, killing 30 Japanese and destroying four pillboxes and two large supply dumps before reaching the O-5 Line. The weak resistance encountered by the patrol suggested that remaining Japanese strength was concentrated in the Umurbrogol Pocket. Thus, at 10:30, Rupertus decided to commit the 5th Marines for a drive to the northern tip of Peleliu. Rapidly relieved by the 1st Marines on eastern Peleliu.
Orders to move to the western portion of Peleliu found the 5th Marines in static positions on Eastern Peleliu, where the regimental mission had been to prevent enemy counterlandings. The 1st Battalion was deployed in the vicinity of the radio direction finding station near Ngardololok, the 2d Battalion was holding the islands north of the northeastern peninsula, while the 3d Battalion, less one company, occupied defensive positions along Purple Beach. The 1st Marines completed the relief of the 5th shortly after noon and assumed command of the 5th Marines sector at that time. In order to expedite movement of the regiment to the West Road, the battalions moved out on trucks at 1300, with 1/5 in the lead, followed by 3/5 and 2/5.
By 1600, the 5th Marines had executed the passage of the lines, and the regiment passed through Phase Line O-4 near Garekoru. As 1/5 continued its advance up the West Road, it encountered erratic resistance from what appeared to be Japanese holdouts. The level terrain was devoid of the dense jungle growth abounding elsewhere on Peleliu and offered ideal conditions for the movement of tanks and LVT flamethrowers accompanying the advance battalion. Aside from occasional Japanese sniper and mortar fire, the advance continued for about 500 yards without interruption to Road Junction 15, where the West and East Roads met. This vital point was defended by a small Japanese force, which had installed itself on a ridge dominating the road forks. Around 1700, as the Marines approached this point, the enemy opened fire, which served only to delay the Marines. When the firefight ended the Japanese had lost 20 killed. The battalion continued its advance for another 100 yards and seized the Japanese radio station, whose towers the forward elements of RCT 321 had spotted on the previous day. Having secured this objective, the battalion established night defenses north of the radio station from the beach to the high ground east of the West Road. Upon reaching Road Junction 15 in the wake of the advance of 1/5, the 3d Battalion pivoted to the southeast and headed down East Road, where it established night defenses on the road and along the western slopes of Hill 80. The latter hill, in itself an isolated terrain feature, owed its importance to its location, for it was the only link separating the Kamilianlul ridges to the south from the Amiangal ridges, which formed the northernmost hill mass on Peleliu.
Throughout the evening and night, the forward elements at the radio station were continuously and heavily attacked and bombed but managed to hold against the enemy onslaught. Meanwhile, at Angaur, after a heavy and prolonged artillery bombardment, the 3rd Battalion, 322nd Regiment pushed forward to launch its assault from the north. Finding no route south over the cliffs, they assembled near the northern end of the Milwaukee Railroad for an attack west the following day. At 07:30 on September 26, the infantry launched their assault on Lake Salome, quickly taking control of the eastern rim with minimal resistance. Facing increasing enemy fire, the Americans made their way down the eastern rim to the bowl floor. However, by the end of the day, they were halted by Goto’s positions on the northern cliffs and "The Island," a gap between an overgrown coral mound and the eastern rim. To the south, the 2nd Battalion supported the attack by advancing north, capturing the southeast rim and clearing out several enemy cave positions.
Back over on Peleliu the Marines had a very rough night full of Japanese infiltrator harassment. In fact our old friend Eugene Sledge wrote about the night of September 25th and what his unit of K Company, 3rd battalion, 5th marines went through.
The Japanese who had come across the road in front of me were probably members of what the enemy called a “close-quarter combat unit.” The enemy soldier shot by Sam was not dressed or equipped like their typical infantryman. Rather he wore only tropical khaki shorts, short-sleeved shirt, and tabi footwear (splittoed, rubber-soled canvas shoes). He carried only his bayonet. Why he entered our line where he did may have been pure accident, or he may have had an eye on our mortar. His comrade angled off toward the right near a machine gun on our flank. Mortars and machine guns were favorite targets for infiltrators on the front lines. To the rear, they went after heavy mortars, communications, and artillery. Before Company K moved out, I went down the road to the next company to see what had happened during the night. I learned that those blood-chilling screams had come from the Japanese I had seen run to the right. He had jumped into a foxhole where he met an alert Marine. In the ensuing struggle each had lost his weapon. The desperate Marine had jammed his forefinger into his enemy's eye socket and killed him. Such was the physical horror and brutish reality of war for us.
The 1/5 spent the early hours of 26 September in consolidating its positions around the radio station and preparing for continuation of its attack later in the day to the northern tip of Peleliu. Shortly after 0600, 3/5 jumped off for an attack against Hill 80 with Company K on the left and Company I on the right. The attack carried the hill and by 0830 the assault force reached a swamp bordering the east coast of Peleliu. This advance of the 3d Battalion was of major importance because it effectively cut the island in two. Late in the afternoon most of the battalion moved back from Hill 80 to a reserve position near the junction of East and West Roads. The unit's southern flank extended south from the junction along East Road to Hill 80, where Company I was stationed for the night. Between Company I, 5th Marines, and the 2d Battalion, 321st Infantry, at Hill B, lay a gap approximately 1,800 yards long through which only the 321st Infantry's Neal Task Force had passed. In this gap lay 1,500-yard-long Kamilianlul Mountain, held by an unknown number of Japanese and as yet not even reconnoitered by American units. The 5th Marines consolidated their positions and resumed their assault.
The 1st Battalion, 5th Marines, ran into stiff opposition from the Amiangal ridges dominating northern Peleliu. The northern portion of the L-shaped hill system consisted of ridges running generally from northeast to southwest for about 1,000 yards; the southern leg extended from northwest to southeast. The southern leg of the ridges was not continuous but broken into four separate hills or knobs, designated from northwest to southeast as Hill 1, Hill 2, Hill 3, and Radar Hill, so named because it had at one time served as an enemy radar installation. These four knobs were to gain ill repute as Hill Row. The entire Amiangal ridge system was held in strength by the Japanese, particularly the portion paralleling the route of advance of 1/5. This part contained some of the most elaborate caves and tunnels on Peleliu. The battalion had barely started out along the West Road when the enemy in and on Hill 1 opened up on the Marines with 37mm and 75mm guns as well as automatic weapons and mortars. This curtain of fire from the Amiangal ridges was reinforced by heavy fire from Ngesebus Island. All forward movement soon halted. Attacking eastward from the West Road, Company B assaulted the second knob, Hill 2, but also encountered opposition. Through sheer determination the company was able to gain a firm foothold on the hill by early afternoon. This accomplishment in effect served to outflank the Japanese on Hill 1, but Japanese resistance on the last mentioned hill continued throughout the day. An attempt by Company C to seize all of Hill 1 during the remaining hours of daylight was unsuccessful, and continuation of the assault had to await the following day. During the bitter fighting in which 1/5 engaged during the night of 25-26 September and for most of the following day, 2/5 remained stationary on the southern flank of the regiment. At 1600 on 26 September, when it had become apparent that 1/5 could make no further progress, 2/5 was ordered to attack. The battalion advanced northward through the left wing of 1/5, carefully bypassing embattled Hill 1. In the course of its advance, the battalion drew heavy fire from Japanese emplacements in the plain, from the ridges on its right, as well as from Ngesebus. Enemy mortars proved especially troublesome. As a result of the heavy fire, Company F lost four of its supporting tanks before it had advanced very far beyond Hill 1. Attempts by the artillery to give all possible support to the battalion were largely ineffectual. "We fired frequent missions throughout the day on these mortars; the reported effect was that the mortars were neutralized while we fired but that they were not destroyed. The enemy apparently withdrew into the caves during the period of our fire." As evening approached, the 5th Marines occupied a jagged front line. The 1st Battalion, though out of contact with the 2d, was tied in with the 3d on the right. The mission of the 3d Battalion was to support either the 1st or 2d Battalion in the event of a major Japanese counterattack. Further progress of the 2d Battalion was impeded by a large antitank ditch, which blocked the approach to the remnants of the Peleliu phosphate plant. The Japanese had converted the reinforced concrete foundation of the otherwise demolished structure into a major defensive installation. Exposed to the enemy fire from Ngesebus Island and plunging fire from caves and defensive positions from the hills, 2/5 found itself in a very unenviable situation.
Further south, after some necessary adjustments, Dark’s forces assaulted Hill B with two battalions. Initially repelled, Dark then sent a task force led by Captain George Neal to attack from the north. After a complex maneuver north and then south, the Neal Task Force attacked Hill B just as other elements of the 321st fought their way to the top through challenging terrain. The hill eventually fell to the Americans, completing the isolation of the Umurbrogol Pocket. By the end of the day, the island was divided in two places, leaving Nakagawa’s determined defenders isolated in two major pockets. On September 27, with the Umurbrogol Pocket now contained, the 5th Marines continued their operations against Amiangal Mountain. At the same time, the 1st Battalion, 321st Regiment advanced north from the Hill B area to close the long gap along East Road up to Hill 80. Dark's infantrymen secured Kamilianlul Mountain with minimal resistance and then moved towards the Marines’ road junction.
The 2d Battalion was to find progress extremely rough for the remainder of the day. First, the erstwhile phosphate plant, which the Japanese had turned into a blockhouse, had to be secured in an area that bristled with snipers. The problem confronting Colonel Harris was a formidable one. The blockhouse in front of 2/5 could not be taken until the antitank ditch blocking the approaches to it had been seized. This was a job that the infantry could not tackle without armored support. The regimental commander decided to utilize all arms available in reducing these obstacles. First of all, Colonel Harris called naval gunfire and artillery in on Ngesebus and any other targets suspected of harboring artillery or mortar positions. A medium tank, equipped with a bulldozer blade, was pressed into service to level the antitank ditch, and filled it by 0830. A LVT flamethrower then was able to come within effective range of the Japanese fortification. Moments later, when the flame and smoke had cleared, all resistance from this stronghold had ceased and more than 60 dead Japanese remained in the rubble. While this action was in progress, patrols from Company E seized a small, weakly defended ridge abutting the road from the east. The 2d Battalion thereafter resumed its advance northward along the road as well as over the adjacent ridge. Company F, at the head of the column, soon found itself embroiled in some of the most bitter and frustrating action of the entire campaign. Aside from receiving heavy Japanese artillery and mortar fire, the company faced a series of pillboxes and field fortifications on level ground, and layer upon layer of caves in the hillsides. Even though they were not aware of it at the time, the men of the 5th Marines had come upon the most skillfully constructed defenses on Peleliu. The Japanese Army had utilized all of the many natural caves possessing tactical value, adapting them for the emplacement of heavier weapons with great ingenuity. On the other hand, Japanese naval troops had preferred to construct their own caves with the help of the 214th Naval Construction Battalion, composed of men who had been professional miners and tunnel workers in civilian life. Since most of these Navy caves were located near the northern end of Peleliu, they proved a serious obstacle to the advance of the 5th Marines. Eugene Sledge faced these obstacles and saw firsthand the effectiveness of flamethrowers. Here is a passage from him:
Burgin's order to us to continue firing into the opening interrupted my musings. We kept up a steady fire into the pillbox to keep the Japanese pinned down while the flamethrower came up, carried by Corporal Womack from Mississippi. He was a brave, good-natured guy and popular with the troops, but he was one of the fiercest-looking Marines I ever saw. He was big and husky with a fiery red beard well powdered with white coral dust. He reminded me of some wild Viking. I was glad we were on the same side. Stooped under the heavy tanks on his back, Womack approached the pillbox with his assistant just out of the line of our fire. When they got about fifteen yards from the target, we ceased firing. The assistant reached up and turned a valve on the flamethrower. Womack then aimed the nozzle at the opening made by the 75mm gun. He pressed the trigger. With a whoooooooosh the flame leaped at the opening. Some muffled screams, then all quiet. Even the stoic Japanese couldn't suppress the agony of death by fire and suffocation. But they were no more likely to surrender to us than we would have been to them had we ever been confronted with the possibility of surrender. In fighting the Japanese, surrender was not one of our options.
Sheer courage and heroism in themselves proved inadequate for the task. In the course of the morning of 27 September, Company F seized the two ridges forming the northwestern anchor of the Amiangal system and established observation posts on the crests. But this did not solve the problem of what to do about the Japanese occupying the caves about half way up the hill. Marine casualties mounted steadily, and evacuation of the wounded became more and more difficult. Since the cave openings completely dominated the road leading past the northernmost ridge of Peleliu, the advance of the entire 2d Battalion ground to a halt. The first tank attempting to squeeze through the narrow gap between the hill and the northwestern shore was hit, and the Marines occupying the crest of the hill were powerless to cope with the caves underneath.
Although the Americans now controlled the northern shore and blocked further enemy reinforcements, skilled Japanese miners continued their resistance underground. What the Marines did not know was that they were facing the most comprehensive cave system on Peleliu which was the underground home of the Japanese naval construction units who were, luckily for the Marines, better miners than infantrymen. The Japanese Army had utilized all of the many natural caves possessing tactical value, adapting them for the emplacement of heavier weapons with great ingenuity. On the other hand, Japanese naval troops had preferred to construct their own caves with the help of the 214th Naval Construction Battalion, composed of men who had been professional miners and tunnel workers in civilian life. Since most of these Navy caves were located near the northern end of Peleliu, they proved a serious obstacle to the advance of the 5th Marines. In the end, it would take weeks for the Marines to finally quash all resistance on Akarakoro Point, then only by blasting closed all the tunnel entrances, sealing the Japanese defenders inside to their fate.
To the south, Harris’ 1st Battalion pressed on with their attack on the mountain's southern leg, successfully capturing Hill 1. Meanwhile, the 322nd Regiment resumed its assault on the Lake Salome bowl, fighting to secure the base of the north rim but encountering less resistance in the south as most Japanese defenders had been evacuated towards Romauldo. The following day, despite a successful enemy mortar barrage that initially forced a temporary withdrawal and reorganization, the Americans cleared the entire bowl floor of Japanese troops, isolating Goto’s remaining forces in the Romauldo area. This progress enabled the 322nd to launch a final coordinated attack on October 1, with its three battalions trapping the enemy in the Romauldo Pocket, though they were unable to penetrate Goto’s final defenses.
On September 28 at Peleliu, while Dark’s 1st Battalion engaged Japanese infiltrators while mopping up the Kamilianlul Mountain area, Harris’ 1st and 2nd Battalions continued their assault on Amiangal and successfully captured Hill 3. This action isolated the remaining Japanese forces at Radar Hill. Meanwhile, the 3rd Battalion, 5th Marines executed a successful landing on Ngesebus Island with minimal resistance after a comprehensive artillery, air, and naval bombardment.
The curtain on the drama of Ngesebus opened on the morning of September 28, when the massed fire of five artillery battalions from Peleliu, as well as heavy fire from warships and aircraft, blanketed the island. Near the northwestern shore of Peleliu, an impressive gathering of high-ranking officers had assembled to witness the operation. The group included such notables as Admiral Fort, and Generals Julian C. Smith, Geiger, Rupertus, Mueller, Oliver P. Smith, and Bell. The weather was cool and cloudy and interspersed with frequent rain squalls. For the Corsair pilots of VMF-114, air support for the Ngesebus landings represented a very interesting and original assignment. The operation marked the beginning of combat work for the squadron, which had reached Peleliu only two days earlier. At 06:30, the Corsairs hit the airstrip on Ngesebus with 500-pound bombs and strafed the entire island as well as Kongauru to the northeast. "Strafing runs were made just a few feet off the deck and a hail of lead laid all over the island." At 08:40, 20 Corsairs preceded the landing craft and gave the island another heavy strafing. In the course of this attack, Japanese mortar positions were spotted and one especially prominent square blockhouse with an iron door was fired on and neutralized. Whenever aircraft were not directly over the island, the artillery on Peleliu and naval guns offshore gave Ngesebus a heavy going over, starting at 07:00 and concluding at 09:05. Both quick and delay fuzes were used. Observers reported that the island was completely covered with fire. In the course of the preliminary bombardment, naval gunfire ships pounded the northern portion of Ngesebus and continued to fire on that part of the island throughout the landing.
The Marines advanced inland, swiftly securing the airstrip and the eastern portion of Ngesebus. One platoon then landed on Kongauru and Murphy islands to secure them against light opposition. However, the attack to the northwest encountered strong resistance from Japanese forces entrenched in caves and dugouts, prompting the deployment of tanks to support the Marine assault. By 5:00 PM, nearly all of Ngesebus was under American control, with only a few hundred yards at the extreme northwestern tip remaining in Japanese hands and some caves on the ridges still needing to be cleared.
The 3d Battalion spent a relatively quiet night on Ngesebus. On the morning of 29 September, Companies I and K resumed the attack. Progress was normal until the two companies had nearly reached the northern tip of Ngesebus, when a 75mm gun opened up at point blank range. The Marines quickly destroyed this weapon and went on to overcome the rest of the resistance on the island. At 1500, 29 September, Ngesebus was declared secure. An hour later, 2/321 relieved the Marines and completed mopping up. Having accomplished the mission on the island, 3/5 returned to Peleliu. The battalion had secured the island at a cost of 15 killed and 33 wounded. In return, the Marines killed or captured 470 Japanese. Infantrymen of 2/321 were to account for another hundred of the enemy during the ensuing mop-up. Eugene Sledge wrote this about the final capture of Ngesebus:
The next morning, again with the help of tanks and am-tracs, our battalion took most of the remainder of Ngesebus. Our casualties were remarkably low for the number of Japanese we killed.* In midafternoon we learned that an army unit would relieve us shortly and complete the job on the northern end of Ngesebus. Our mortar section halted to await orders and dispersed among some open bushes. In our midst was the wreckage of a Japanese heavy machine gun and the remains of the squad that had been wiped out by Company K. The squad members had been killed in the exact positions to be occupied by such a squad “according to the book.” At first glance the dead gunner appeared about to fire his deadly weapon. He still sat bolt upright in the proper firing position behind the breech of his machine gun. Even in death his eyes stared widely along the gun sights. Despite the vacant look of his dilated pupils, I couldn't believe he was dead. Cold chills ran along my spine. Gooseflesh tickled my back. It seemed as though he was looking through me into all eternity, that at any instant he would raise his hands—which rested in a relaxed manner on his thighs—grip the handles on the breech, and press the thumb trigger. The bright shiny brass slugs in the strip clip appeared as ready as the gunner, anxious to speed out, to kill, and to maim more of the “American devils.” But he would rot, and they would corrode. Neither he nor his ammo could do any more for the emperor.
The rest of the 5th Marines continued their operations on September 29, launching a full-scale assault on Radar Hill using flamethrowers, bazookas, and demolition charges, finally capturing the position by the morning of September 30. Following the completion of operations in northern Peleliu, the 5th Marines were relieved by the 321st Regiment. However, as the Army troops took over, the remaining Japanese, who had been hiding underground, reoccupied some positions, requiring two additional days of fighting to fully secure northern Peleliu. Nonetheless, the Japanese presence in Peleliu had now been reduced to Nakagawa’s Umurbrogol Pocket, so Peleliu was officially secured. Total losses during this battle so far included 843 killed, 3845 wounded and 356 missing of the 1st Marine Division; 46 killed, 226 wounded and 7 missing from the 321st Regiment; and an estimated 9076 Japanese dead plus 180 prisoners of war. Yet that is all for today with Peleliu and Anguar as we now need to travel to China where the Japanese are still carrying out Operation Ichi-Go in an effort to capture Guilin and Liuzhou.
As we last observed, General Yokoyama's 11th Army had taken control of Lingling Airdrome and Quanzhou by September 14. Following this, they reorganized their units in preparation for resuming their offensive in October. Meanwhile, the 34th Division was deployed towards Changning, and the 37th Division moved to capture Shaoyang, which fell by the end of the month. The 23rd Army also made final preparations for their offensive in early September. General Tanaka directed the Kawakami Raiding Unit in a wide flanking maneuver along the Zhukeng-Huaiji road towards Wuzhou, while the 23rd Independent Mixed Brigade embarked on a long march north to Guiping. On September 13, the 22nd Independent Mixed Brigade and the 22nd and 104th Divisions began their main advance towards Wuzhou. However, the Kawakami Raiding Unit successfully captured Wuzhou on September 22 and seized the Danzhuzhen airfield six days later. Each unit then continued its advance westward to Guiping, which fell to the 23rd Brigade on October 11. So far, Tanaka’s forces had encountered little to no resistance, but this was about to change.
After the war, in discussing the performance of the Chinese divisions supposed to defend Guilin and Liuzhou, the political situation in east China, and the attitudes of the east China commanders, Marshal Hata remarked that in his opinion Li Zongren and Bai Chongxi had kept their forces out of serious fighting in order to conserve them "for the future." At the time, there were rumors that these men were planning a coup against Chiang Kai-Shek. Chinese resistance was light, but with its supply situation improved the 14th Air Force again did its best on the Salween as well as in east China. In all September the force dropped 1897.6 tons of bombs and fired 1281382 rounds of machine-gun ammunition, some of the latter of course at aerial targets. In early September, Japanese fighter reinforcements from the homeland also entered combat. The Japanese were pleased at the performance of the latemodel fighters with one of the air regiments they sent to China. Thanks to the air cover thus supplied, for the first time in the east China campaign they found themselves able to move supplies regularly on the Xiang Jiang, which paralleled their line of advance, and so thought their prospects "brightened."
At the beginning of the month, Yokoyama renewed his offensive, with the 58th Division successfully taking Xing’An and the 34th Division capturing Changning. The 37th Division was then deployed to Dao, and the 34th Division was sent to Xing’An in preparation for the final push toward Guilin. On October 20, this attack commenced as Yokoyama directed the 216th Regiment to advance to Lehecun, the 58th Division to assault the area north of Guilin, the 40th Division to move to Gaoshangzhen, the 13th Division to advance to Quanhuicun, and the 3rd Division to push toward Fuchuan. With minimal resistance from the retreating Japanese forces, most of these movements were completed by the end of the month. The 3rd Division pushed further to Pingle, while the 37th Division occupied Gongchengzhen and Yanshan to approach Guilin from the south. On November 3, the 3rd Division captured Lipu and began preparations for the advance towards Liuzhen, encircling Guilin and opening the route to Liuzhen.
Meanwhile, on October 22, Tanaka ordered the reinforced 23rd Brigade to continue its advance toward Guigang, with the 104th and 22nd Divisions pushing toward Wuxuan. Their progress, previously unopposed, was now challenged by the Chinese 46th and 64th Armies, which launched daily attacks against Guiping with substantial air support. As a result, the 22nd Division was redirected to counter the Chinese forces, successfully forcing their withdrawal by October 29. Following this victory, the 23rd Brigade captured Guigang on November 3, and the 104th Division seized Wuxuan the following day. This allowed Tanaka’s forces to begin a northern pursuit to support Yokoyama’s assaults on Guilin and Liuzhen.
After the third Anshan strike, General LeMay began implementing reforms within the 20th Bomber Command. These changes included reorganizing the command, enhancing the logistics system, adjusting target priorities, and improving coordination with Pacific operations. As a result, the frequency of missions increased each month, with each mission becoming more substantial and effective. Concurrently, following the successful completion of the newly renamed Isley Field on Saipan, the 73rd Bombardment Wing was redirected to the Marianas instead of the CBI Theater. There, it would join Major-General Haywood Hansell’s 21st Bomber Command, tasked with executing high-altitude, daylight precision attacks to cripple Japan's aircraft industry.
The XXI Bomber Command arrived on Saipan on October 12, 1944, and from the start General Hansell was beset by a host of serious command problems, the worst of which were continued teething problems with the B-29, tardy delivery of aircraft, aircrews untrained in high altitude formation flying, primitive airfield conditions, lack of an air service command for logistical support, no repair depots, a total absence of target intelligence, stubborn internal resistance to daylight operations by his sole combat wing, subordinates in the XXI Bomber Command who lobbied for his removal, and Hansell's inferiority in rank in dealing with other AAF commanders in the theater. Furthermore, Hansell was soon prohibited from flying combat missions with his command, possibly because of limited knowledge of the atomic bomb or the perception that he knew the existence of Ultra.
As plans for a sustained bomber offensive against Honshu progressed, the strategic focus of Operation Matterhorn diminished. The 20th Bomber Command shifted to flying missions in direct support of other Pacific operations, with target priorities moving from coke ovens to the aircraft industry. In preparation for the upcoming invasion of the Philippines, the command was tasked with two closely spaced maximum missions against Okayama in Formosa, totaling 170 sorties, along with very-long-range reconnaissance missions. Yet now we have to travel over to the India-Burma theater. As the advance towards the Chindwin continued and the resilient 33rd Division finally crossed the river in late November, General Katamura was finalizing his plans for a withdrawal to the Mandalay sector, scheduled for December. This decision was driven by the intense pressure the British 36th Division was putting on General Takeda’s defensive positions at Pinwe, forcing the defenders to prepare for a final retreat by the end of November. Meanwhile, General Slim was preparing for Operation Capital. He planned to stretch airpower to its limits to move four and two-thirds divisions across the Chindwin, along with two tank brigades. After establishing bridgeheads at Sittang, Mawlaik, and Kalewa, he intended to cross the Chindwin and confront General Kimura’s forces between the Chindwin and the Irrawaddy. The 4th Corps, now under the experienced General Messervy, would break out from the Sittang bridgehead, advance east through the mountains, capture Pinlebu, and then approach the Shwebo plain from the north. Simultaneously, General Stopford’s 33rd Corps would move from Kalewa, following the Chindwin southeast to Yeu and Monywa. Once the Japanese forces were pushed onto the open plain, Slim planned to exploit his overwhelming advantage in airpower and tanks to decisively defeat them, anticipating that the enemy would fiercely defend Mandalay.
The combination of the defeats at Kohima, Imphal, Mogaung and Myitkyina meant that by the autumn of 1944, Kimura’s role was reduced to defending southern Burma as the northern flank of their new ‘South-East Asia defense zone’. With few reinforcements or supplies to look forward to, Kimura had grim prospects. On paper he had ten divisions (2nd, 15th, 18th, 31st, 33rd, 49th, 53rd, 54th, 55th, & 56th), though this was really seven, since little remained of the three divisions that had been devastated at Kohima-Imphal. He also had the dubious support of Bose’s INA and Aung San’s seven-battalion Burma National Army, but the civilian population was increasingly going over to the side of the likely winners. Unexpectedly, Kimura received 30000 fresh troops in the period June–October, but his problem was more commissariat than raw numbers, since he was rapidly running out of supplies. Even those he had (45000 tons of food, 500 lorries and 2000 pack animals) were difficult to get to the front, and Kimura was painfully aware that the situation could only get worse. The South-East Asia zone was slowly being throttled by the Allied naval blockade, all approaches to Rangoon were mined, and in 1944 total Japanese shipping losses amounted to 2.3 million tons. Even those ships that ran the blockade would proceed no farther than Penang in Malaya.
Kimura chose to deploy smaller units to delay the British-Indian forces while the main body of the 15th Army retreated across the Irrawaddy River. His strategy was to launch a counterattack once the British crossed the river, aiming to replicate a reverse Imphal by wearing down the British-Indian forces through attrition and then destroying them during their retreat in the May 1945 monsoon. Meanwhile, Admiral Mountbatten was also seeking a victory of his own. On November 8, he ordered an assault on Japanese positions in Arakan, with a deadline set for the end of January. This operation was assigned to General Christison’s 15th Corps.

The fighting on Peleliu and Angaur raged asAmerican forces struggled against resilient Japanese defenses. Significant advances were made, including the isolation of the Umurbrogol Pocket and the capture of Ngesebus Island. Despite heavy casualties, Peleliu was eventually secured, leaving a small pocket of Japanese resistance.

17 9月· The Pacific War - week by week
Last time we spoke about the invasion of the Palau Islands. General Rupertus’s 1st Marine Division was tasked with attacking Peleliu, while General Mueller’s 81st Division would land on Angaur. Prior to the landings, extensive neutralization of Japanese airfields was carried out by Allied forces. On September 6, carrier-based aircraft attacked the Palaus, significantly damaging enemy targets but encountering minimal resistance. The invasion fleet, led by Admiral Fort, began landing operations on September 15. Despite strong Japanese defenses, especially around Peleliu’s rugged coral ridges, the Marines made some progress but faced intense resistance. Notable figures such as Eugene Sledge, author of “With the Old Breed,” provided personal insights into the brutal conditions faced. The landing saw heavy casualties and challenges, including ineffective pre-landing bombardments and fierce counterattacks, but the Marines managed to secure key positions by the end of the first day. The 81st Division then proceeded with landings on Angaur on September 17, facing lighter resistance but difficult terrain.

Last time we left off, Peleliu and Anguar had just been amphibiously assaulted by US Marines. While the landings on Angaur were underway, General Rupertus pressed on with the Peleliu offensive on September 17. In the southern sector, Colonel Hanneken’s 7th Marines made headway against the isolated Japanese defenders. The 3rd Battalion cleared a minefield and captured the southeast promontory, while the 1st Battalion took on the southwestern promontory but only managed to secure half of it due to fierce enemy resistance. To the north, the 1st and 5th Marines advanced further, encountering the Umurbrogol Mountains for the first time, where Colonel Nakagawa had fortified his defenses. On the left flank, Colonel Puller’s 1st and 3rd Battalions encountered minimal opposition as they moved along the relatively flat coastal plain but had to halt their advance when the 1st Battalion was impeded by a reinforced concrete blockhouse. On the right, Colonel Harris’ 2nd Battalion progressed well while staying hidden from Japanese artillery and mortar fire. However, despite reaching their objectives by mid-morning, Harris’ 1st Battalion faced difficulty when Puller’s 2nd Battalion, after making initial gains, was halted by the Umurbrogol defenses. They fought hard to secure Hill 200 but were immediately met with fire from the next ridge. Additionally, Harris’ 3rd Battalion was pinned down by heavy flanking fire from the left. That night, additional armor was sent to the 7th Marines to support the ongoing operations in the south. The next morning, Hanneken’s 3rd Battalion launched a final assault. During the night of D+2, additional armor (tanks and 75mm gun-mounted halftracks) was brought up and at 10:00 on September 18 the advance was resumed. Again progress was painfully slow with many reserve elements being attacked by Japanese from bypassed caves and underground emplacements. At 13:44 elements of Companies A and C reached the southern shores, though the area being assaulted by Company B was still heavily defended. Tank support had withdrawn to re-arm and before Company B was in a position to resume the attack, a bulldozer was needed to extricate the gun-mounted half-tracks, which had become bogged down. At that time, several explosions were heard from the Japanese defenses and it was found that remaining Japanese defenders had finished the job for the Marines. The final handful leaped from the cliff tops into the sea in an effort to escape, only to be picked off by Marine riflemen. With the taking of the two promontories, the southern part of Peleliu was secured. 1/7 and 3/7 squared themselves away for a well-earned rest, while headquarters reported "1520 hours D+3, 7th Marines mission on Peleliu completed." Unfortunately, this was not quite the case. Despite the slow progress and intense Japanese resistance, the Marines managed to secure the southern portion of Peleliu by the end of September 18.
At the same time, the 1st and 5th Marines continued their fierce and costly push north. On the right flank, Colonel Harris’s 2nd Battalion faced only sporadic resistance as it cut through the dense jungle. The Americans eventually reached a causeway leading east to Peleliu’s northeastern peninsula, a potentially dangerous obstacle to their advance. After a successful patrol, Harris opted to call in an airstrike before crossing, but the strike missed its target and hit the area while the Marines were crossing. Despite this, the bridgehead was established, though further casualties were incurred due to friendly artillery and mortar fire. With this new foothold, Harris redirected his 3rd Battalion eastward across the causeway to support the 2nd Battalion’s advance. On the left flank, the 1st Marines, having sustained 1,236 casualties, were urged by Rupertus to "maintain the momentum." This led Colonel Puller to commit all available reserves, including engineers, support personnel, and Hanneken’s reserve 2nd Battalion. The 1st Marines suffered about 240 casualties during the 17th and in Japanese counterattacks the ensuing night; the 3rd Battalion was reduced to about one third of its original strength; and two companies of the 1st Battalion were practically finished as fighting units. On the other hand, there was some reason for optimism. Progress on the 17th had been measured in hundreds of yards in the rough, high ground at the southern end of the central ridges and strong Japanese resistance had been overcome. Whatever optimism may have existed was not to last too long. On the 18th, in what the Marine Corps' history of the operation characterizes as "savage and costly fighting," elements of the 1st and 7th Marines managed to advance more than 500 yards in the center, principally along the ridge lines and hills oriented north and south. But the advance during the day was held up at a group of peaks which seemed at first to form a continuous ridge line that was oriented more east and west than the rest of the Peleliu ridges. Soon, the name Five Sisters came to be applied to a cluster of peaks forming the western side of the terrain feature. A towering hill at its eastern extremity, separated from Five Sisters by a saddle, was designated Hill 300, or Old Baldy. With the 7th Marines held up in the center, at Five Sisters, the units on both sides of the central ridges halted so as not to create exposed flanks. Puller’s 3rd Battalion made progress along the coastal plains but had to pause to stay in contact with other units. Meanwhile, the 2nd Battalion struggled against the Umurbrogol Mountains, capturing Hill 210 before being forced to withdraw due to a fierce Japanese counterattack on Hill 200 behind them. At Anguar, following a three-hour artillery bombardment supported by aircraft, General Mueller’s 321st and 322nd Regiments resumed their advance north and west with tank support. After linking their advances, Colonel Venable pushed west and reached the high ground where Major Goto had established his main defenses, while Colonel Dark made significant progress south until his forces encountered the formidable defenses at Green Beach.
The night of 18-19 September was noisy and nerve-racking all along the front and few troops got much sleep. Minor Japanese attacks harassed the exposed salient held by the 3d Battalion, 322d Infantry, while bats and large land crabs helped the Japanese to create distraction and started troops firing on nonexistent enemy infiltrators. Apparently no casualties resulted either from Japanese action or indiscriminate small arms fire. Friendly artillery fire did, however, cause some casualties. About 2030, four or five 105-mm. shells from the 316th Field Artillery Battalion hit the lines of the 2d Battalion, 321st Infantry, killing 4 men and wounding 15 others. The artillery fire was stopped before further damage could be done.
On September 19, following a night of numerous Japanese infiltrations and small-scale counterattacks, the 322nd Regiment swiftly secured Saipan Town and advanced to the north shore of Garangaoi Cove. Meanwhile, the 321st Regiment successfully attacked and captured the Green Beach fortifications from their vulnerable side. To manage the exposed Japanese forces on the beaches, Dark’s 2nd Battalion, supported by tanks, maneuvered left and progressed down the southwest of the island, halting just short of the shoreline by nightfall. At Peleliu, Harris’ Marines made headway towards the Ngardololok area, overcoming light resistance and quickly dispatching the few enemy stragglers they encountered, reaching Purple Beach by day's end. However, in front of the O-3 line, Puller’s weary troops, having endured a grueling night of Japanese counterattacks, resumed their assault on the Umurbrogol Mountains.
Despite some local advances, by evening on 20 September the 1st Marines had been stopped and, ". . . as an assault unit on the regimental level, had ceased temporarily to exist," having suffered almost 1,750 casualties, well over half its strength. Relief was absolutely necessary, not only because casualties were heavy but also because the survivors were physically exhausted from heat, lack of water, and continuous combat. Elements of the 7th Marines therefore relieved all 1st Marines units except those along West Road. While the 7th Marines took over from the exhausted 1st Marines on the right, the 5th Marines continued their advance through western Peleliu, securing its two peninsulas, including Island A and Ngabad Island, by September 21. General Mueller, concerned lest the Japanese reported on the south break through gaps or weak points in the forward lines, had special defenses in depth set up at RED and BLUE Beaches, utilizing Shore Party and antiaircraft troops. All units were alerted to expect Japanese attacks during the night. The division expected (and perhaps hoped) that the Japanese still believed to be located in southern Angaur might launch a suicidal desperation charge during the night or at dawn on the 20th. The night proved very quiet until, toward morning, some small, scattered Japanese parties infiltrated through the lines of both regiments. There was no banzai effort--rather, these Japanese troops were apparently attempting to escape to the northwest hill mass from positions in the mangrove swamp and GREEN Beach 3 areas. Action at dawn was limited to a mopping-up operation directed against four Japanese discovered in the headquarters area of the 2d Battalion, 321st Infantry. By 11:00 on September 20, Mueller reported to General Geiger that all organized resistance on Angaur had ended and that the island was secure.
General Mueller's statement was probably prompted by his realization that the remaining Japanese were compressed into the northwest hills and by the reports that about 850 of the enemy had been killed through the 20th. This casualty figure was an overestimation. Probably fewer than 600 Japanese had been killed through the 20th, and Major Goto still had possibly 750 men with which to conduct an organized defense in the northwest. On orders from General Inoue, Goto planned no final banzai attack which would decimate his forces. Instead he withdrew over half his force to rugged terrain and emplaced them in natural or prepared fortifications. His lines of defense in the northwest were well conceived; many of his positions were mutually supporting; the amphitheater configuration of the bowl provided him with defensive areas whence heavy cross fires could be directed at attackers; the broken coral, with its crevices, fissures, caves, and ridgelets, gave him defensive advantages at least as good as those at the Ibdi Pocket on Biak; and he had available a number of artillery and anti-tank weapons, heavy and light mortars, and heavy and light machine-guns, most of them so emplaced as to give maximum support to his riflemen. In addition, he could still exercise effective control over the men he had gathered in the Lake Salome bowl. For whatever it was worth, Goto was ready to conduct a protracted defense, though the best he could hope for was to tie down the 322nd Regiment. Nevertheless, the real issue at Angaur--securing the prospective airfield area--had already been decided.
To the north, while southern Angaur was being secured, Venable’s men were probing the enemy's northwestern defenses with a series of company-sized attacks. These attacks allowed the Americans to gather crucial information about Goto’s remaining positions, centered around the Lake Salome bowl. Venable discovered that organized resistance was still strong, prompting him to rearrange his units for a final push. Following a heavy artillery and air bombardment, the 322nd Regiment attacked the bowl with tank support, initially making some gains but soon encountering obstacles due to the terrain and enemy fire. By the end of September 21, Venable deemed the newly gained positions too exposed and decided to withdraw to the previous night's defenses. Meanwhile, the 1st and 7th Marines continued to face heavy casualties as they fought through the Umurbrogol Mountains, with the latter advancing less than 175 yards after two days of intense combat. Nakagawa’s fierce defenders managed to halt the 1st Marine Division on the rough and well-defended terrain, resulting in a total of 4,000 casualties by this time. After visiting the front, Geiger decided to replace the battered 1st Marines with Dark’s 321st Regiment, which had suffered minimal casualties and had completed its mission at Angaur. The 1st Marines by this time reported 1749 casualties. One Marine later described the fighting in the Umurbrogol, which attests to the level to which the 1st Marines had deteriorated: "I picked up the rifle of a dead Marine and I went up the hill; I remember no more than a few yards of scarred hillside, I didn't worry about death anymore, I had resigned from the human race. I crawled and scrambled forward and lay still without any feeling towards any human thing. In the next foxhole was a rifleman. He peered at me through red and painful eyes. I didn't care about him and he didn't care about me. As a fighting unit, the 1st Marines was finished. We were no longer human beings, I fired at anything that moved in front of me, friend or foe. I had no friends, I just wanted to kill."
OnSeptember 19, he also dispatched Colonel Arthur Watson's reserve 323rd Regiment to secure Ulithi Atoll. After a successful reconnaissance mission, the infantrymen landed on September 22, discovering that the atoll’s airfield and seaplane base had been abandoned by the Japanese. The Americans later established a major advanced fleet anchorage, a Marine airbase, and a Navy seaplane base there. Ulithi Atoll contained a 300-berth anchorage and a seaplane base. Occupation of these Western Caroline islands provided still another base from which future operations against the enemy could be supported. The construction of an airstrip on Ameliorate Island made possible fighter plane protection for the anchorage and afforded a base from which US aircraft could continue neutralization of the nearby Japanese bases on Yap. Together with Angaur and Peleliu Islands to the southwest and Guam, Tinian, and Saipan to the northeast, the capture of Ulithi Atoll completed a line of American bases that isolated Japanese holdings in the Central and South Pacific. The occupation of Ulithi Atoll further denied it to the enemy as a fleet anchorage, weather and radio station, and possible air and submarine base, in addition to precluding its use by the enemy to observe and report the activities of American forces in the sector. By September 25 the unloading of all the support ships had been completed and Vice Admiral John H. Hoover, Commander, Forward Areas Western Pacific, took over the task of developing Ulithi Atoll into an advanced fleet base. Within a month after its capture, more than 100 Navy craft from self-propelled types to lighters, floating drydocks, barges, landing craft, and seaplane wrecking derricks were en route to the island. During subsequent operations in the Philippines, the Pacific Fleet found Ulithi to be an extremely valuable base. Prior to the invasion of Okinawa, the island served as a staging area for fleet and amphibious forces. The atoll thus fulfilled a vital strategic role in the final phase of the Pacific War.
On that day, Venable resumed his assault on the Lake Salome bowl. The coastal offensive faced little resistance, but the attack through the southern defile encountered heavy enemy fire. Despite this, the troops reached the shores of Lake Salome. However, Venable was severely wounded during the action and had to be evacuated, with his troops retreating to more defensible positions by nightfall. The main strength of the attack was placed on the right (southeast) section of the bowl, and tanks fired along the eastern rim about 200 yards in front of the leading elements. The mediums had been undisturbed by enemy fire all morning, but, apparently attracted by an incautious grouping of officers and men near the lead tanks and defile exit, a Japanese anti-tank gun opened fire from a hidden emplacement along the east rim. Three officers (including Colonel Venable, who was in the forward area to observe the new attack) and one enlisted man were severely wounded and had to be evacuated. During the retirement on the 22nd, one of the three forward tanks was so badly damaged by a mine or buried shell that it could not be moved through the defile. This tank blocked the defile's northern entrance and prevented the withdrawal of another medium, which had to be destroyed to keep it from falling into Japanese hands. In four days of fruitless effort to push into the bowl from the south, three tanks and two 75-mm SPM's had been lost. Heavier infantry losses also began to be sustained now that the Japanese, cornered, were fighting to the death. On that day, for instance, the 2nd Battalion lost 2 men killed and about 35 wounded.
At 0730 on the morning of the 23d, the 2d Battalion, with Companies B, C, and E attached, continued the attack into the bowl from the south. Companies B and C worked up the east shore of Lake Salome. Companies I and G pushed toward the southwest and western shores, while Company F paid particular attention to caves along the southwest rim of the bowl. During the first part of the attack all companies moved forward rapidly, and Company I reached the northwest corner of the lake without much trouble. But Company B, pushing forward against increasingly heavy Japanese fire from the north, was pinned down by this fire when it reached the northeast corner of the lake. Company C was sent north on B's right to try to outflank the enemy machine gun and mortar positions from which the fire on Company B originated. The intention was to flush the Japanese from their positions and push them southwest and south against the main body of the 2d Battalion. But Company C could make little progress toward the northern section of the bowl, and its own position became precarious as Japanese mortar and machine gun fire increased and the 1st Battalion's own 81-mm. mortar ammunition ran out, making further mortar support impossible. Japanese fire continued to increase and the positions of all forward companies became untenable. A general withdrawal to the defile entrance was ordered. The withdrawal was painfully slow; companies were broken up; all units suffered more casualties. One small group of Company I, separated from its parent unit, worked over the cliffs and ridges at the bowl's western rim to the coast at BLACK Beach. Company B, retreating in small segments, lost men as it withdrew from the northeast corner of the lake. All told, the 2d Battalion and attached companies lost 18 men killed and over 75 wounded during the day.
Concurrently, as the 1st and 7th Marines continued to struggle with the formidable Umurbrogol Mountains, Harris’ Company G successfully secured the undefended Carlson Island, finally completing the 5th Marines' original mission. Despite concerns about a potential enemy attack on Koror and Babelthuap after the Peleliu operation, General Inoue decided to reinforce Nakagawa’s beleaguered garrison. By 21 September effective Japanese infantry strength in the central ridges was down to 1,300 men. That, of course, does not paint a true picture of the situation in the central pocket. A trained soldier, well armed, can be tenacious on the defense in such terrain as the central ridges of Peleliu whether or not he be trained for infantry service. There were probably 4,000 Japanese troops (including the 1,300 infantrymen) still firmly ensconced in the central pocket as of 21 September, and there were at least 1,000 more troops in the Amiangal Mountain area at northern Peleliu. Nevertheless, Colonel Nakagawa, commanding the Peleliu Sector Unit, clearly needed reinforcements if he was to hold out much longer. There were perhaps 30,000 Japanese troops in the northern Palaus to draw from, including two battalions of the 59th Infantry, two battalions of the 15th Infantry, and four or five recently organized infantry battalions of the 53d Independent Mixed Brigade.
The Japanese were not to reach their destination undetected. At 0535, the destroyer H.L. Edwards spotted seven enemy barges about 1,000 yards northeast of Akarakoro Point at the northern tip of Peleliu, obviously headed for the island. The destroyer opened fire, sinking one barge before the remainder reached the beach. A combination of bombing and strafing, naval gunfire, and artillery hit the barges on the beach, and by 0845 the cruiser Louisville reported all barges destroyed. The enemy version of this incident agrees only in part with the American account, adding that "despite receiving severe enemy air and artillery fire at a point two kilometers off the coast, they made a successful landing at 0520 hours under the command of 1st Lieutenant Murahori".
Knowing that some Japanese forces had reached Peleliu, Rupertus decided to deploy his own reinforcements between the central ridges and the western shore, targeting the enemy's weak spot for an offensive up the western coast. The 7th Marines supported the Army by attacking enemy positions from the south and center, with Hanneken’s 3rd Battalion advancing along the high ground to the right rear of the 321st. After relieving the 1st Marines, Dark sent patrols up the coastal flat to Garekoru, encountering little opposition initially. However, Dark’s 2nd Battalion faced heavier resistance in the afternoon and had to retreat, postponing the northward advance until the next day. During the night, Inoue sent the remainder of the 2nd Battalion, 15th Regiment, and despite being shelled, most reinforcements reached Peleliu. By September 23, the Americans had secured important footholds on Peleliu and Angaur. However, intense fighting remained, with the 321st Regiment relieving the 1st Marines against Nakagawa’s fortified positions, while the 322nd Regiment continued to attack Goto’s defenses on the northwest hills. Yet that is it for the Palau’s as we now need to turn to Mortai.
General Persons’ troops quickly secured and expanded the island perimeter, successfully repelling the enemy's night raids with little difficulty. An example of these raids is the September 18 attack. This is the Japanese report: “On 18 September the main body of the 2nd Provisional Raiding Unit, which had moved into position along the upper Tjao, launched a strong night infiltration attack with the objective of disrupting the enemy's rear area in the vicinity of Doroeba and Gotalalmo. Although deep penetration of the enemy lines was achieved and considerable casualties inflicted, the attack failed to reduce the beachhead or to interfere with the enemy's rapid preparation of Doroeba airfield.” In truth, the Americans easily repelled this attack, suffering very few casualties. These raids would continue throughout September and October.
American engineers were busy constructing a new fighter strip at the Pitoe Drome area. This strip was scheduled to be ready for use by September 29 but was eventually abandoned and downgraded to an emergency field. A number of factors influenced the decision to abandon the site, which was renamed Pitoe Crash Strip. Japanese air reaction had been so ineffectual that the need for a fighter base on Morotai was not as urgent as had been expected. Aircraft based on escort carriers, some of which remained in the Morotai area for weeks, were able to keep away most of the Japanese planes, and their efforts were supplemented by long-range land-based fighters from Sansapor. Moreover, the line of approach which planes had to use to land on Pitoe Crash Strip interfered with that of the more important bomber base at Wama Drome. Finally, the terrain at the crash strip was by no means as well drained as that at other locations on the Doroeba Plain, and it was necessary to expend much engineer effort to keep the strip operational.
The new field, which acquired the designation Pitoe Drome, was located about 1,200 yards north of Wama Drome. Construction proceeded slowly at Pitoe Drome because so much engineer effort had to be devoted to the completion of Wama Drome. By 4 October almost 7,000 feet at the new site had been cleared, but it was not until the 17th, D plus 32, that even one runway was surfaced, let alone taxiways and dispersal lanes. Meanwhile, the construction of a new bomber field at Wama Drome faced significant delays due to heavy rainstorms and a shortage of suitable surfacing material. Despite almost constant struggles with soggy ground and tropical downpours, engineers managed to make 4,000 feet of Wama Drome operational by October 4. However, the overall progress on building Morotai’s new airbase, intended for the upcoming invasion of the Philippines, was slower than anticipated. Nevertheless, the Tradewind Task Force was disbanded on September 25, as the island was considered secure enough. General Hall then assumed command of the Morotai base as the commander of the 11th Corps. However, unbeknownst to the Americans, who believed the only possible Japanese response to the invasion was the ineffective air raids already carried out against them, troops in Halmahera were preparing to embark on a dangerous mission to reinforce Morotai and contest control of this key island.
In the meantime, after the successful invasion of the Palaus, new developments were unfolding on the Philippines front following Admiral Mitscher’s Task Force 38's recent successful strikes. These strikes had revealed an unexpected vulnerability in the enemy's air defenses, prompting Admirals Halsey and Nimitz to cancel the Yap operation, thereby freeing up many resources for the Philippines Campaign. Approximately 500 aircraft, or about 57% of the 884 believed to be in the Philippines, were rendered nonoperational or destroyed during these air attacks. Consequently, General MacArthur decided to cancel the preliminary Mindanao operations and instead make a direct jump from the Palaus-Morotai line to Leyte on October 20. Shortly after this change in schedule, MacArthur informed the Joint Chiefs that he could advance from Leyte to Luzon by December 20, two months earlier than planned. Meanwhile, the carrier raids on Mindanao and the Visayas strengthened the Southern Army command's belief that the Allies were preparing for an early invasion of the Philippines. As a result, Marshal Terauchi recommended accelerating the reinforcement of the Philippines, activating Operation Sho-Go, and authorizing the 4th Air Army to employ its main strength against enemy carrier task forces. This was in contrast to the current policy of not committing available air strength against enemy raiders, which was failing to conserve Japanese air power for a decisive battle. However, Tokyo denied these last two requests while also receiving concerning reports about General Kuroda’s neglect of his duties as field army commander. In the middle of September, IGHQ decided to replace General Kuroda with General Yamashita. Not only did General Kuroda have a concept of the Philippine operations that differed from that of his superiors, but he was charged with neglecting his duty as field army commander. Lt. Col. Yoshie Seiichi of the Personnel Bureau of the War Ministry, who had been sent to the Philippines to investigate personnel matters in the Southern Army, said of the incident: “Stories reached the War Ministry that Lt. Gen. Kuroda was devoting more time to his golf, reading and personal matters than to the execution of his official duties. It appeared that his control over staff officers and troops was not sufficiently strong and that there was a good deal of unfavorable criticism of his conduct among the troops. There were also indications that discipline was becoming very lax. On September 4, I left Tokyo under orders . . . to investigate. As a result I obtained many statements substantiating the unfavorable stories in regard to Lt. Gen. Kuroda. The recommendations of all the staff was that Lt. Gen. Kuroda be relieved as soon as possible, and be replaced by Gen. Yamashita . . . who was a superb tactician and excellent leader.” Random note, for those interested, over on my personal podcast at the Pacific War Channel I did a single episode covering how Yamashita became the Tiger of Malaya and plan to do more pieces on him as I find him to be one of the more interesting generals of the Pacific War.
Before an effective change in command could take place, the Japanese were about to experience a more dramatic display of Allied offensive power that they would soon encounter in the Philippines. On September 18, Mitscher’s Task Force 38 was ordered to head back toward the islands for a major strike against Luzon, the heart of Japanese control in the Philippines. The American carriers achieved complete surprise and successfully attacked Luzon three days later. Despite the fierce defense by approximately 42 Zeros, between 09:30 and 18:00 on September 21, four waves of over 400 aircraft targeted the harbor area and airfields around Manila with bombs and strafing runs. The assault on the harbor and shipping along the west coast resulted in the sinking or severe damage of 34 vessels totaling over 100,000 gross tons, while the raids on the airfields inflicted significant damage on grounded aircraft. At 0610 the following day, 22 September, search planes discovered the enemy carrier groups still lurking off the coast of Luzon, and at 0730 a hit-and-run attack was carried out by 27 Japanese aircraft, with reported bomb hits on two carriers and one cruiser. Naval air units at Legaspi attempted to carry out a second attack on the enemy carriers during the late afternoon, but the attack force of 19 planes failed to locate the carrier groups. Following the failed Japanese hit-and-run counterattack, Mitscher continued his assaults on Manila, destroying an estimated 110 aircraft in the air and 95 on the ground, and sinking or damaging 44 vessels. After the apparent withdrawal of enemy carriers, the Japanese decided to relocate their remaining ships in Manila Bay to other anchorages, many of which were directed to the secure docks of Coron Bay. However, Mitscher’s carriers returned on September 24 to launch further strikes against Luzon, including a raid by about 96 Hellcats and 24 Helldivers on Coron Bay, which resulted in the sinking or damaging of 10 more vessels. Additional attacks on other targets led to the sinking or damaging of 12 more ships.
Despite the ongoing air attacks, the Imperial Japanese Navy still deemed it premature to fully activate Operation Sho-Go, believing the decisive battle would take place in or after late October. Meanwhile, the Imperial Japanese Army accelerated its preparations to defend the Philippines. The reserve 1st Division was ordered to move to the islands immediately, and plans were made to assign ten surface raiding regiments to the area. On September 26, as plans for air reinforcement to the Philippines were being approved, General Yamashita was confirmed as the new commander of the 14th Area Army. He arrived in the Philippines on October 6 and found the situation "unsatisfactory," with poor planning for the Leyte campaign and many of his staff unfamiliar with the conditions in the Philippines. Lt. Gen. Makino Shiro, now commanding the 16th Division, which was the major force on Leyte, had directed his efforts since April 1944 toward the construction of defensive positions on the island. The first line of defense, which was on the east coast in the Dulag area, was practically completed by the middle of October. The third defensive line was in the middle of Leyte Valley in the vicinity of Dagami. The second line of defense was between the two others, while the bulk of supplies was assembled in the central mountain range at Jaro. The distribution of the other troops at the time of the American landings was as follows: one battalion of the 9th Infantry Regiment in the Catmon Hill and Tanauan district, and the main strength of the 33d Infantry Regiment in the Palo and Tacloban area. The larger part of the 33d Infantry Regiment, which was less adequately trained than the other regiments, had arrived on Leyte in mid-September from Luzon. Its officers were unfamiliar with the terrain and did not fortify their positions.
However, the supply situation was favorable, with Manila serving as the main Japanese depot in the region. Following established plans, he instructed his subordinates that the Area Army would "seek decisive battle on Luzon" while in the central and southern Philippines, the focus would be to delay the enemy's advance and prevent them from securing naval and air bases. However, the September air strikes had led to a noticeable increase in guerrilla activity and civil disorder due to widespread destruction and panic. Small Japanese garrisons were attacked, pro-Japanese Filipinos molested and intimidated, and communications disrupted. In central Luzon there were indications that some guerrilla units were planning a move to the Lamon Bay area in order to be the first to cooperate with an American landing force, and on Negros and Panay guerrilla raids on Japanese airfields became boldly persistent. The Fourteenth Area Army feared that, as soon as enemy forces landed, the guerrillas would not only give them direct assistance as scouts and guides, but seriously hamper Japanese operations by attacking rear communication lines. Consequently, martial law was declared across the archipelago in anticipation of enemy landings.

Despite fierce and costly combat, American forces made significant advances in the Palaus, securing critical islands and establishing bases. The battle for Peleliu was marked by high casualties and intense fighting, with heavy losses on both sides. The successful capture of strategic locations like Ulithi Atoll and the subsequent strikes on Luzon further demonstrated Allied dominance and strategic planning in the Pacific Theater.

- 147 - Pacific War Podcast - Invasion of the Palau Islands 9 - September 18 - , 1944
10 9月· The Pacific War - week by week
Last time we spoke about the invasion of Morotai. After capturing the Marianas and Sansapor, the Allies planned to invade the Palaus and Halmahera. The Japanese stationed the 14th Division at Palau and the 32nd Division at Halmahera. General Ishii, with 11,000 troops, defended Halmahera's nine airfields, while Major Kawashima led 500 Formosans on Morotai. Meanwhile Colonel Nakagawa commanded the forces at Peleliu with extensive defenses, emphasizing attrition tactics. The Allies planned Operation Stalemate for Peleliu and Angaur, with General Geiger's corps set to land on September 15. Aerial reconnaissance and submarine missions informed their strategy. At Morotai, Operation Tradewind was executed by General Krueger’s 31st Division. Supported by air and naval bombardment, Allied troops swiftly secured key areas, encountering minimal Japanese resistance. These operations were part of broader Allied strategies involving coordinated air support and subsequent invasions in the region.
This episode is the Invasion of the Palau Islands

In last weeks episode we talked about the plans and preparations for the invasion of Palau. General Rupertus’ 1st Marine Division was assigned to assault Peleliu while General Mueller’s 81st Division would conduct a dual-pronged landing on Angaur. Meanwhile, Admiral Hoover’s land-based aircraft, General Kenney’s Allied Air Forces, and Admiral Mitscher’s carrier-based aircraft carried out an extensive neutralization program against Japanese airfields within range of Palau. When fighter planes of three fast carrier groups started sweeping over the Palaus on September 6, they found that the efforts of the Southwest Pacific's land-based bombers had succeeded in eliminating many ground targets. Nevertheless, fighters and bombers of the three groups started full-scale attacks on all the principal islands in the Palaus the next day. There was no air opposition, nor had there been any on the 6th. On the 8th, because observable targets were scarce, the weight of attack was reduced, and the carriers began preparing to move to Philippine waters. During their three days at the Palaus, the carrier-based planes flew about 1470 sorties, causing extensive damage to ammunition and supply dumps, barracks, warehouses, and a number of miscellaneous buildings. The groups claimed destruction of only four enemy aircraft, while losing eight of their own.
Admiral Fort’s slower-moving tractor groups, responsible for transporting both divisions to the islands, departed Guadalcanal with their respective screening forces on the morning of September 4. Four days later, fast transports and LSDs also set out to rendezvous with them in the early hours of September 15 after an uneventful voyage. In the interim, Admiral Davison’s carrier group launched a final sweep over the Palaus on September 10. The next day, Rear Admiral Jesse Oldendorf’s Western Fire Support Group and Rear Admiral Ralph Ofstie’s escort carriers arrived to begin the naval gunfire bombardment. Over the following three days, approximately 2,200 tons of naval projectiles were successfully fired on Peleliu. While Japanese positions pinpointed by the fire support ships were generally destroyed, many hidden by natural or man-made camouflage remained intact, as did those in areas not accessible to naval gunfire. Minesweepers cleared the 670 mines laid by the Japanese in the Peleliu-Angaur region and at least 240 more in the Kossol Passage. Nearly 175 mines were destroyed in the four days leading up to the landings, with the remaining mines marked at the cost of one minesweeper. Underwater demolition teams also began clearing obstacles from the landing beaches on September 12, providing the Japanese with clues about the Allied landing plans, leading them to hastily lay many land mines in the last few days.
By 05:15 on September 15, Fort’s transports had finally gathered off the Palaus and taken their assigned positions in the transport areas, ready for the landings to begin. Under clear skies, the small craft and amphibian vehicles of the assault waves formed up without difficulty and moved toward the reefs in front of Peleliu’s White and Orange Beaches. At 05:30, Oldendorf’s cruisers and destroyers started the pre-landing bombardment of the beaches, which was scheduled to cease at 07:50 to allow the carriers to conduct a final sweep. Ten minutes later, the first assault wave began advancing, supported by an LCI rocket barrage and aerial strafing attacks. However, the pre-landing bombardment had been inefficient, leaving many Japanese positions intact. Artillery and mortar fire quickly targeted the American amtracs, with several LVTs taking direct hits. Approximately 26 were destroyed during the landings, their burning hulks cluttering the beaches. Despite the smoke from Japanese fire and burning amtracs, the first wave reached the shore at 08:32. Colonel Chesty Puller’s 1st Marines landed on the left, Colonel Harold Harris’ 5th Marines in the center, and Colonel Herman Hanneken’s 7th Marines on the right. For those of you interested, a rather famous marine was with Harris’s 5th marines this day. Serving with K Company, 3rd battalion, 5th Marines was Eugene Sledge, the author of “with the Old Breed” probably the most famous Pacific War book of all time. If you are a fan of the HBO series: the Pacific, it was based loosely off this book amongst others. I think overall with the Old Breed does an outstanding job, particularly for when it was written, to showcase the brutal reality of the war in the Pacific. Eugene Sledge did not sugar coat things or gloss over terrible things he saw his fellow marines do, such as ripping out gold teeth from dead or even alive Japanese as well as taking human trophies like skulls or hands. Here is a passage:
We learned that our battalion would leave Peleliu as soon as a ship was available to transport us back to Pavuvu. By day we rested and swapped souvenirs, but we had to be on the alert at night for possible Japanese movement. To the south we could hear the constant rattle of machine guns and the thud of mortars and artillery as the 81st Infantry Division kept up the pressure around the Umurbrogol Pocket. “Have you gone Asiatic?” I gasped. “You know you can't keep that thing. Some officer'll put you on report sure as hell,” I remonstrated as I stared in horror at the shriveled human hand he had unwrapped. “Aw, Sledgehammer, nobody'll say anything. I've got to dry it in the sun a little more so it won't stink,” he said as he carefully laid it out on the rock in the hot sun. He explained that he thought a dried Japanese hand would be a more interesting souvenir than gold teeth. So when he found a corpse that was drying in the sun and not rotting, he simply took out his kabar and severed the hand from the corpse, and here it was, and what did I think? “I think you're nuts,” I said. “You know the CO will raise hell if he sees that.” “Hell no, Sledgehammer, nobody says anything about the guys collecting gold teeth, do they?” he argued. “Maybe so,” I said, “but it's just the idea of a human hand. Bury it.” He looked grimly at me, which was totally out of character for his amiable good nature. “How many Marines you reckon that hand pulled the trigger on?” he asked in an icy voice. I stared at the blackened, shriveled hand and wondered about what he said. I thought how I valued my own hands and what a miracle to do good or evil the human hand is. Although I didn't collect gold teeth, I had gotten used to the idea, but somehow a hand seemed to be going too far. The war had gotten to my friend; he had lost (briefly, I hoped) all his sensitivity. He was a twentiethcentury savage now, mild mannered though he still was. I shuddered to think that I might do the same thing if the war went on and on
Its a gripping read, highly recommend it, especially for quote en quote normie friends you might want to get into the Pacific War. Back to the story.Rupertus’ objectives for the first day were to push inland 300 yards to objective line O-1, then attack and capture O-2. Landing simultaneously with the fourth wave were the division's tanks (M-4 Shermans). Because of their excellent waterproofing for the operation, they successfully negotiated the reef, where the worst of the underwater obstacles had been removed by UDTs, and continued toward land in six parallel columns led by their respective LVT guides. The enemy fire, however, proved so intense that over half of 30 tanks organic to the division suffered from one to four hits during the 10 minutes necessary to cross the reef. In the 1st Marines' zone, for example, only one of the assigned tanks escaped being hit during the trip ashore. only three, however, were completely knocked out of action. "Thus within a half hour after the initial landing the infantry had full tank support--a record unsurpassed in any previous Marine landing in the Central Pacific, except for the Marshalls."
To make matters worse, no sooner had the lead elements of 3/1 landed and advanced less than 100 yards inland, than they found themselves confronted by a most formidable natural obstacle, a rugged coral ridge, some 30ft high. This had not shown up on any maps. Worse, the face of this ridge (christened "The Point" by the Marines) was honeycombed with caves and firing positions which the Japanese had blasted into the coral and had turned into excellent defensive positions which resisted all initial assaults. Even after tanks arrived to support the assault troops attempting to storm the northern portion of the ridge, they stumbled into a wide, deep anti-tank ditch, dominated by the ridge itself. Here they came under severe and accurate enfilading fire and were pinned down for hours.
The loss of much communication equipment further left Puller and Rupertus unaware of the situation on the left flank. A major effort was then launched to assault The Point from the rear. It became apparent to the Marines that The Point was unassailable from the front and so eventually units fought inland and assaulted The Point from the rear. These units, commanded by Capt George P. Hunt, fought their way along The Point for nearly two hours, during which time they succeeded in neutralizing all of the enemy infantry protecting the major defensive blockhouses and pill boxes. The principal defense installation was a reinforced concrete casement built into the coral, mounting a 25mm automatic cannon, which had been raking the assault beaches all morning. This blockhouse was taken from above by Lieutenant William L. Willis, who dropped a smoke grenade outside the blockhouse's embrasure, to cover the approach of his men, and Corporal Anderson who launched a rifle grenade through the firing aperture. This disabled the gun and ignited the ammunition inside the blockhouse. After a huge explosion, the fleeing Japanese defenders were mown down by waiting Marine riflemen.
Hunt's surviving 32 men remained isolated on The Point for the next 30 hours, constantly under attack from Japanese infiltrators. Meanwhile, Puller's 2nd Battalion pushed inland about 350 yards against moderate resistance. Despite this success, the 1st Marines' front was divided by two huge gaps. Puller's 1st Battalion was then committed to support the Marines on the left, successfully gaining a foothold on the southern area of The Point, but still unable to close the critical gaps. In the center, Harris' 1st Battalion advanced through coconut groves that provided ample cover, successfully reaching O-1 to link up with Puller's 2nd Battalion in front of the airfield by 09:30. On the right, however, Harris' 3rd Battalion and Hanneken's 3rd Battalion experienced a confused landing and made no progress, with only Harris' Company I reaching O-1 an hour after landing. At 10:30, the two battalions began pushing inland. Harris' Company K rapidly advanced deep into Peleliu's interior under the cover of fairly dense scrub, while the 7th Marines used a large anti-tank ditch to move forward in relative safety.
Again I thought it give more flavor if I took a passage from this moment when K Company advanced from Sledge:
We started to move inland. We had gone only a few yards when an enemy machine gun opened up from a scrub thicket to our right. Japanese 81mm and 90mm mortars then opened up on us. Everyone hit the deck; I dove into a shallow crater. The company was completely pinned down. All movement ceased. The shells fell faster, until I couldn't make out individual explosions, just continuous, crashing rumbles with an occasional ripping sound of shrapnel tearing low through the air overhead amid the roar. The air was murky with smoke and dust. Every muscle in my body was as tight as a piano wire. I shuddered and shook as though I were having a mild convulsion. Sweat flowed profusely. I prayed, clenched my teeth, squeezed my carbine stock, and cursed the Japanese. Our lieutenant, a Cape Gloucester veteran who was nearby, seemed to be in about the same shape. From the meager protection of my shallow crater I pitied him, or anyone, out on that flat coral
Hanneken soon faced strong opposition, leading him to pause his troops and request tank support in the afternoon. The requested tank support became somewhat confused by an unexpected coincidence: the flank battalions of the two assaulting regiments in the center and right were both the 3rd (3/5 and 3/7) with both containing Companies I, K, and L. The unfortunate tank commanders looking for 3/7 who had wandered into 3/5 area due to obstacles - in particular the large anti-tank ditch on Orange 3 - enquired of a body of troops they encountered "is this Company I, 3rd Battalion?" Hearing the right answer in the wrong place, they proceeded to operate with these troops, who were in fact Company I of 3/5 and not Company I of 3/7. Happily, this was one of those confusions of battle that helped more than it hindered. The confusion resulted in a gap between the two regiments as 3/7 paused to take stock of the situation, whereas 3/5 was actually pushing ahead. In an effort to re-establish contact with 3/5, Company L of the 7th Marines worked patrols further and further to the left until its foremost patrol emerged on the southern edge of the airfield. This was completely out of its regimental zone of action and several hundred yards to the rear of the units it was looking for.
By this time, Harris’ 2nd Battalion and Hanneken’s 1st Battalion had landed, with Harris’ battalion pushing vigorously northeast, while Hanneken’s battalion dealt with fierce Japanese resistance and a dense swamp to the south as they advanced toward O-1. Concerned about the slow progress on the right and the heavy casualties suffered by Hanneken’s forces, Rupertus decided to land the divisional reconnaissance company. However, the reserve 2nd Battalion, 7th Marines could not be disembarked until the next day.
One major Japanese counterattack occurred at around 16:50hrs on D-Day, consisting of a tank-infantry sortie in force across the northern portion of the airfield. This attack had been expected by the Marines, especially those of the 5th Marines facing open ground in front of the airfield, and accordingly the regimental commanders had brought up artillery and heavy machine guns as well as tanks to support that area. Increase in Japanese artillery and mortar fire in that area was the first indication that something was brewing. Soon after Japanese infantry was observed advancing across the airfield, not as a fanatical, drunken banzai charge but as a coolly disciplined advance of veteran infantrymen. A Navy air observer spotted Japanese tanks forming east of the ridges above the airfield with more infantry riding on them. These tanks moved forward, passing through the Japanese infantry advancing across the airfield and some 400 yards in front of the Marine lines. For a moment, but only for a moment, the Japanese counter-attack looked like a serious coordinated movement. Then the formation went to pieces. Inexplicably, the Japanese tank drivers opened their throttles wide and raced towards the Marine lines. Charging like the proverbial "Bats outa Hell," with the few infantry atop the tanks clinging on for dear life, they left their accompanying infantry foot support supp far behind. No positive account exists of what happened thereafter. The tanks involved in the charge numbered between 13 and 17 (insufficient pieces were left afterwards to give a definite count) and headed for the Marine lines, cutting diagonally across the front of 2/1, who subjected them to murderous flanking fire from all weapons, small arms, light and heavy machine guns, 37mm antitank guns and artillery. Two of the Japanese tanks veered off into the lines of 2/1, hurtling over a coral embankment and crashing into a swamp, the escaping crews were quickly disposed of by the Marines. Meantime, the remaining tanks came under heavy fire from the marines of 1/5, while the advancing Japanese infantry was subjected to fire and bombing from a passing Navy dive bomber. The tanks and their riding infantry were decimated as they passed right through the Marine lines which simply closed behind them.
At 17:00, a heavy mortar barrage struck Harris’ 3rd Battalion’s command post, causing the Marine companies to lose cohesion, though they eventually formed a defensive line along the airfield's edge. Under this barrage Eugene Sledge had this to say:
Under my first barrage since the fast-moving events of hitting the beach, I learned a new sensation: utter and absolute helplessness. The shelling lifted in about half an hour, although it seemed to me to have crashed on for hours. Time had no meaning to me. (This was particularly true when under a heavy shelling. I never could judge how long it lasted.) Orders then came to move out and I got up, covered by a layer of coral dust. I felt like jelly and couldn't believe any of us had survived that barrage.
By the end of the day, despite 210 men killed and 901 wounded, the progress of the beach expansion was disappointing. Again Eugene Sledge has a passage about getting through the first heat of combat on D-day at Peleliu:
We had to be alert constantly as we moved through the thick sniper-infested scrub. We received orders to halt in an open area as I came upon the first enemy dead I had ever seen, a dead Japanese medical corpsman and two riflemen. The medic apparently had been trying to administer aid when he was killed by one of our shells. His medical chest lay open beside him, and the various bandages and medicines were arranged neatly in compartments. The corpsman was on his back, his abdominal cavity laid bare. I stared in horror, shocked at the glistening viscera bespecked with fine coral dust. This can't have been a human being, I agonized. It looked more like the guts of one of the many rabbits or squirrels I had cleaned on hunting trips as a boy. I felt sick as I stared at the corpses. A sweating, dusty Company K veteran came up, looked first at the dead, and then at me. He slung his M1 rifle over his shoulder and leaned over the bodies. With the thumb and forefinger of one hand, he deftly plucked a pair of hornrimmed glasses from the face of the corpsman. This was done as casually as a guest plucking an hors d'oeuvre from a tray at a cocktail party. “Sledgehammer,” he said reproachfully, “don't stand there with your mouth open when there's all these good souvenirs laying around.” He held the glasses for me to see and added, “Look how thick that glass is. These sonsabitches must be half blind, but it don't seem to mess up their marksmanship any.” He then removed a Nambu pistol, slipped the belt off the corpse, and took the leather holster. He pulled off the steel helmet, reached inside, and took out a neatly folded Japanese flag covered with writing. The veteran pitched the helmet on the coral where it clanked and rattled, rolled the corpse over, and started pawing through the combat pack. The veteran's buddy came up and started stripping the other Japanese corpses. His take was a flag and other items. He then removed the bolts from the Japanese rifles and broke the stocks against the coral to render them useless to infiltrators. The first veteran said, “See you, Sledgehammer. Don't take any wooden nickels.” He and his buddy moved on. I hadn't budged an inch or said a word, just stood glued to the spot almost in a trance. The corpses were sprawled where the veterans had dragged them around to get into their packs and pockets. Would I become this casual and calloused about enemy dead? I wondered. Would the war dehumanize me so that I, too, could “field strip” enemy dead with such nonchalance? The time soon came when it didn't bother me a bit.
During the night, coordinated local counterattacks were repelled with relative ease, thanks to the support from naval gunfire and the artillery of the 11th Marines. However, the enemy’s resistance, which was not the frenzied banzai charges of previous encounters, began to suggest that the prolonged and organized opposition Rupertus had anticipated might indeed persist for a longer time. Meanwhile, with the 3rd Battalion, 15th Regiment cut off to the south, Nakagawa chose to withdraw most of his forces to the ridgelines and high ground north of the airfield, aiming to hold out as long as possible. The 1st Marine Division, enduring a night of harassment from Japanese mortar and artillery fire, faced heavy resistance from these ridgeline defenses on September 16. Despite this, after landing on Peleliu at 09:50, Rupertus made significant progress that day. His only adjustment was to order the reserve 2nd Battalion, 7th Marines to support Puller’s beleaguered 1st Marines to "maintain momentum." On the right flank, the 7th Marines pressed their hold on the southern part of the island despite heavy resistance and thick scrub, capturing all but two small promontories at the southern tip, where isolated defenders established their final positions. In the center, the 5th Marines cleared most of the remaining airfield area and set up defenses at night in a hangar and shop area on the field’s north side, while Puller’s 2nd Battalion secured the northwestern section of the airfield, including several headquarters buildings and barracks.
On the left flank, the 1st Marines struggled to advance against the determined and well-coordinated resistance from Nakagawa’s main defenses, which were concentrated around the Umurbrogol Mountains. Only after intense fighting and with the help of tanks did the Marines manage to capture a 500-yard stretch of the ridge. By nightfall, at the cost of approximately 30 additional men killed and 115 wounded, the division had established a perimeter extending over 3,000 yards from north to south, and about 2,000 yards deep at its farthest point. Over the course of two days, the Americans suffered nearly 1,500 casualties, with more than 1,000 from Puller’s 1st Marines alone. Despite these losses, the crucial objective—the Peleliu airfield area—had been secured. The Japanese defenses had been divided, with two small pockets in the south and the main stronghold in the central ridges. Feeling that operations were progressing well and possibly aiming to keep Peleliu an all-Marine endeavor, Rupertus decided not to request reinforcements from the 81st Division. Consequently, General Mueller’s forces were set to proceed with landings on Angaur the next day. Rear-Admiral William Blandy, commanding the Angaur Attack Group, reported that based on air and naval bombardments, hydrographic surveys, and UDT activities, a successful landing on Angaur appeared achievable. Admiral Fort and General Geiger thus approved the decision. Meanwhile, Major Goto Ushio had stationed his 1,400 men from the reinforced 1st Battalion, 59th Regiment in four defensive sectors with a small reserve in the center.
Expecting the Americans to land on the well-prepared Green Beaches to the southeast, he had fortified that area with his strongest coastal defenses. However, the Americans anticipated this and chose instead to land Colonel Benjamin Venable’s 322nd Regiment on Red Beach to the north and Colonel Robert Dark’s 321st Regiment on Blue Beach to the east. In the early hours of September 17, Blandy positioned his forces off Angaur and at 0530 the Angaur Fire Support Group started its bombardment, employing for the most part slow, methodical area fire rather than shooting at specific targets. The fire was characterized by the 81st Division as being "very satisfactory," and it accounted for about 40 percent of all naval shells thrown at Angaur from 12 through 17 September.
Due to a delay in the arrival of support aircraft, the shore bombardment continued past the scheduled time while General Mueller’s assault troops boarded the landing craft and amphibian vehicles meant to take them ashore. By 08:00, the LVT assault waves began positioning themselves at the line of departure, while the 323rd Regiment executed a feint at Green Beach to distract the Japanese from the actual landing sites. Ten minutes later, the assault waves moved toward the shore, supported by LCI rocket fire, ongoing bombardments, and strafing planes that had also arrived late. Despite encountering only light mortar and small-arms fire, Dark’s forces successfully landed on Blue Beach at 08:31, just one minute behind schedule. Venable’s first wave, however, was delayed and arrived at Red Beach six minutes late. Subsequent waves landed throughout the day amid light resistance but faced challenges such as traffic congestion and limited beach space. By 16:45, all tanks of the 710th Tank Battalion were ashore, and the 316th and 906th Field Artillery Battalions had successfully landed at Red Beach by nightfall. The artillery for Blue Beach was landed the following day. Additionally, Venable’s reserve 2nd Battalion landed by 11:30, and Dark’s reserve 1st Battalion arrived by 13:00.
After landing, Mueller’s green regiments began advancing inland about 300 yards to their first phase line, quickly becoming entangled in dense scrub forests teeming with Japanese machine guns and snipers. On Blue Beach, Dark’s troops proceeded cautiously at first, but by noon they had secured Rocky Point, Cape Ngariois, and established a beachhead approximately 1200 yards long and 350 yards deep. Meanwhile, Venable’s 1st Battalion moved swiftly north and inland through less dense undergrowth to secure its designated beachhead area. The 3rd Battalion bypassed some enemy bunkers set in jagged coral and proceeded south and west, successfully linking up with the 1st Battalion but falling short of reaching Cape Ngatpokul. With two secure beachheads and a 700-yard gap along the first phase line between regiments, Mueller ordered the 322nd Regiment to extend its right flank onto the second phase line about 400 yards inland and to continue pushing south with its left flank towards the sister regiment. By 14:30, the advances resumed, with Venable’s 1st Battalion pushing westward against light resistance into increasingly rough terrain along the coast and into a densely overgrown basin near the north end of Lake Aztec. Meanwhile, the 3rd Battalion engaged in patrol actions against isolated Japanese positions to secure the coastal area between the two landing beaches, though little progress was made. Dark’s forces also struggled, hindered by difficult terrain and mounting Japanese resistance.
Ignoring the gap between regiments, Mueller ordered Venable’s 3rd Battalion to advance to the second phase line. The battalion moved along railroad beds without encountering opposition, reaching the objective by nightfall. Simultaneously, Dark attempted to advance to the second phase line but made little progress before having to dig in. Goto, on the other hand, chose not to launch an immediate mass counterattack, believing that the 81st Division might land at other beaches. Instead, he deployed a company-strength mobile reserve for a counterattack, but this effort was disrupted by air and naval gunfire before it could commence. By late afternoon, realizing that the Americans had firmly established themselves ashore, Goto began moving his units and withdrew the southern defense force to the northwest hills for a final stand. To cover this movement, he ordered a night counterattack by two companies. At 05:50 on September 18, enemy infantry emerged from cover below Rocky Point and attacked Dark’s Company B, pushing the Americans back about 75 yards before being halted by a heavy concentration of fire. Meanwhile, small groups of Japanese forces repeatedly assaulted the defensive line south of Lake Aztec, near the boundary between the 1st and 3rd Battalions. Despite their efforts, they failed to exploit the gap between regiments and withdrew to the northwest hills shortly after dawn.

- 146 - Pacific War Podcast - Invasion of Morotai 2 - September 9 - , 1944
3 9月· The Pacific War - week by week
Last time we spoke about the end of Operation Dan. In Yunnan, by late July, General Wei's Y Force worked to eliminate Japanese garrisons at Tengchong, Mount Song, Pingda, and Longling. The 33rd Army prepared for Operation Dan, anticipating resistance from General Honda's garrisons until September. The fall of Myitkyina prompted Honda to expedite his plans. Reinforcements were expected in Mandalay by September. General Matsuyama's forces, cut off and surrounded, provided support only through radio messages. At Tengchong, Colonel Kurashige vowed to defend against relentless attacks. Chinese forces, after intense fighting and bombing raids, breached the city's defenses. Despite heavy casualties, the Japanese resisted fiercely. Major Kanemitsu’s garrison defended Moung Song with dwindling supplies. The Chinese forces employed siege tactics and underground mines to break Japanese strongholds. The Chinese launched coordinated attacks, capturing key positions and ultimately compelling Japanese retreats.

After the Marianas fell and Sansapor was captured, the Allies set their sights on their next objectives: the Palaus and Halmahera, slated for simultaneous invasion by mid-September. The Japanese had stationed the 14th Division at Palau and the 32nd Division at Halmahera as their primary defenses. The Halmahera-Morotai area had not assumed much importance to the Japanese until early 1944, when they began to develop Halmahera as a focal point for the defense of the southern approaches to the Philippines. In addition to the 32d Division, the Japanese had on Halmahera innumerable service organizations, and they completed or had under construction nine airfields on the island, most of them in northern Halmahera. On that island they concentrated nearly 30,000 men, including at least 11,000 combat troops.
On Halmahera, General Ishii commanded approximately 11,000 troops to safeguard nine airfields, despite having already lost most of their air power. Meanwhile, Morotai Island was defended by around 500 Formosans of the 2nd Raiding Unit, led by Major Kawashima Takenobu. General Ishii planned to counterattack from Halmahera if the Allies landed on Morotai, but soon realized Allied air and naval superiority would foil these efforts. Following their defeat in the Marianas, Tokyo reassigned the Bonin Area Group directly under its command and placed the Palau Area Group under the Southern Army, leaving General Mugikura’s 31st Army to defend Truk and other isolated outposts. General Inoue fortified Palau with elaborate defenses along the coast and inland, manned by 21,000 Imperial Japanese Army (IJA) troops, 7,000 Imperial Japanese Navy (IJN) personnel, and 10,000 laborers.
The IJN had by 1944 constructed numerous reinforced concrete blockhouses and bunkers plus dug an extensive tunnel system near the end of the northeast peninsula as well as taking full advantage of Peleliu's natural caves. This elaborate, multi-level tunnel system could shelter 1000 troops. These defenses, tunnels, the airfield, and the many support facilities were built by the 204th, 214th, and 235th Construction Battalions, mostly manned by Koreans and Okinawans. Detachments of the guard forces manned eight 120mm dual-purpose, and about three 200mm coast defense guns. There was no ammunition for the 200mm short guns nor did any ships report being fired on by coast defense guns. The 114th and 126th Anti-aircraft Units manned single and twin-barreled 25mm automatic guns (estimated at 30) and 13.2mm machine guns. A dozen 20mm cannons, removed from destroyed aircraft, were set up on makeshift mounts, mostly around the airfield. His strategy emphasized prolonged attrition over suicidal charges, aiming to exhaust the American forces. In preparation for the intense pre-landing bombardment, Inoue instructed his troops to utilize natural terrain features like coral caves and sinkholes, tactics that proved effective against the advancing Allies.Based in Koror, the Japanese commander stationed Colonel Nakagawa Kunio’s 2nd Regiment on Peleliu, the reinforced 1st Battalion of the 59th Regiment on Angaur, and deployed the 15th and 59th Regiments across Babelthuap and other islands. Major-General Yamaguchi Takeo’s 53rd Independent Mixed Brigade defended the central islands, complemented by 4,000 personnel from the Imperial Japanese Navy on Peleliu.
Prior to General Inoue’s arrival in the Palaus, the defense of the Palaus had been under the command of Vice-Admiral Ito Yoshioka. Upon his arrival on Koror, where he established his headquarters, Inoue appointed Colonel Nakagawa Kunio as Peleliu's new commander, with his 2nd Regiment (Reinforced). Nakagawa was a most able commander, possibly one of Japan's finest defensive tacticians, in the same league as General Kuribayashi on Iwo Jima. Nakagawa would make full use of all his defenses and troops on Peleliu, making the Americans pay dearly for every inch, as he had been ordered to do. Although a very capable commander, the appointment of an Army colonel over a Navy vice-admiral caused a great rift between the Army and Navy on Peleliu, which deteriorated into farce. To resolve matters and calm the Navy down somewhat, Inoue sent Major-General Murai Kenjiro from his headquarters on Koror Island to Peleliu to provide the Army with sufficient rank to satisfy the vice-admiral's honor, although the defense of Peleliu seems, to practical purposes, to have remained in the hands of Nakagawa. It appears that Murai, after inspecting Nakagawa's defensive works and battle plans for the defense of Peleliu, was content to let Nakagawa continue without interference from himself, lending only the weight of his rank to acquire the required cooperation of the Navy elements on Peleliu.
Nakagawa, divided the island into four defense sectors, each manned by an infantry battalion. His 1st Battalion, alongside the 14th Division Tank Unit and Engineer Company, served as a mobile reserve for counterattacks against potential landings. Meanwhile, Admirals Nimitz and Halsey had been planning Operation Stalemate, targeting Palau since May 29. Originally slated for September 8, General Geiger’s 3rd Amphibious Corps would assault Peleliu and Angaur, with General Hodge’s 24th Corps landing on Babelthuap.
Intelligence was gathered by aerial reconnaissance photographs. Also, in June 1944 the submarine USS Seawolf (SS-197) carried out photographic reconnaissance of the invasion landing beaches. A further reconnaissance was carried out by the submarine USS Burrfish (SS-312) on Peleliu and Yap beaches. An 11-man reconnaissance group of underwater demolition team (UDT) frogmen landed on the Peleliu beaches from the Burrfish for closer investigation relating to water depth, location of potholes and sandbars, and obstacles. With thousands of Japanese on the island they understandably did not reconnoiter inland, and the rugged terrain of the interior would come as an unpleasant surprise to the Marines. A similar operation was carried out on the Yap invasion beaches, but this time only two of a five-man reconnaissance team made it back to the pick-up point. After several unsuccessful attempts to locate their missing comrades the remaining two men returned to the Burrfish. After this incident, Admiral Nimitz banned any further missions of this type. Given delays in the Guam operation, Operation Stalemate was canceled on July 7, replaced by Stalemate II.
An unusual staff arrangement was established to plan Stalemate II. IIIAC was committed to take Guam under General Geiger. The IIIAC staff would thus be unable to plan the Palaus operation, which it was to execute. Consequently, Major General Julian Smith, designated to command the Expeditionary Troops, was tasked to plan the operation using his own small staff augmented by some IIIAC staff officers. This temporary planning staff was designated X-Ray Provisional Amphibious Corps. It would plan the operation and IIIAC would execute it – an awkward arrangement, but necessary in order to maintain the increasing tempo of operations. As Commander, Expeditionary Troops, Smith was also to be in control of all ground action in the western Carolines; a position roughly analogous to that of General Krueger of ALAMO Force in the Southwest Pacific. X-Ray was finally dissolved on August 15, 1944. This revised plan scheduled Geiger’s forces to land on Peleliu with the 1st Marine Division and on Angaur with the 81st Division on September 15, while the 77th Division remained in floating reserve and the 5th Marine Division in area reserve.
Then, on October 8th, the 24th Corps planned to launch an assault on the islands of Yap and Ulithi in the western Carolines. This was aimed at securing an additional airfield and fully neutralizing Truk and the remaining islands in the group. For this operation, Halsey divided his 3rd Fleet into two main echelons: his Task Force 30, which included covering forces such as Admiral Mitscher’s Fast Carrier Task Force (now Task Force 38), and Admiral Wilkinson’s Task Force 31, the Joint Expeditionary Force. At Peleliu, General Rupertus’ 1st Marine Division was to land with five battalions advancing over the White and Orange Beaches on the southwest coast. The 1st Marines were to land on the left, pushing up the western shore to clear Japanese forces from ridges overlooking the airfield; the 5th Marines would land in the center to secure the airfield; and the 7th Marines on the right to capture the southern end of the island. Meanwhile, at Angaur, Major-General Paul Mueller’s 81st Division planned a two-pronged amphibious assault. The 322nd Regiment was to land on Red Beach on the northeast coast, while the 321st Regiment would land on Blue Beach about 2000 yards to the southeast. Both forces would then push inland to secure a first phase line approximately 300 yards from the beaches, before continuing their advance west and south. The reserve 323rd Regiment was tasked with a feint landing at Beach Black on the northwest coast, with potential deployment to Ulithi if the Palau operations proved successful.
Meanwhile, General MacArthur aimed to establish an airbase in the Halmahera area, strategically positioned between the Vogelkop and Mindanao. This location would provide crucial flank protection against Japanese forces in the Dutch East Indies and support land-based operations for the upcoming invasion of Mindanao. Optimistically, in mid-June, MacArthur had tentatively scheduled the invasion of Mindanao for October 25. Nimitz, however, believed that MacArthur's hope of reaching Mindanao by October 25 was too optimistic. During conferences at Pearl Harbor in July, called at the suggestion of Nimitz to coordinate Southwest and Central Pacific plans for the Morotai, Palau, and Mindanao operations, Southwest Pacific planners learned that less amphibious craft and assault shipping could be made available to them than had previously been anticipated. Moreover, restudy of range and weather factors made it appear somewhat risky to depend upon the ability of Morotai-based aircraft to provide air support for Southwest Pacific forces on Mindanao after carriers had to leave the latter area and before airdromes could be developed there. To obtain adequate land-based air support for the Mindanao invasion force, MacArthur returned to discarded plans to seize air-base sites on the Talaud Islands, about equidistant from Morotai and Sarangani Bay, Mindanao, where the first landings in the Philippines were then scheduled to take place. The employment of amphibious means for the Talaud operation would delay preparations for Mindanao, as would the development of airdromes on the Talauds. Finally, to have the invasion of Mindanao take place much before the middle of November would involve a conflict in timing with anticipated employment of assault shipping and carrier support by Admiral Nimitz for the occupation of Yap and Ulithi in the western Carolines, an operation scheduled for the first week in October. MacArthur therefore revised his program to call for the invasion of Morotai on September 15, the Talauds on October 15, and Mindanao on November 15.
As Allied carriers were engaged in the Palau operation, MacArthur needed a target within range of fighters and medium bombers stationed at Sansapor. Thus, Morotai Island was chosen for Operation Tradewind due to its perceived light defenses and ample space for airfield and light naval base facilities. General Krueger selected the 31st Division and the 126th Regiment, totaling approximately 28,000 troops under the overall command of General Hall's 11th Corps, for this operation. Admiral Barbey's Task Force 77, comprising 12 destroyers, 2 APAs, 5 APDs, 1 LSD, 39 LCIs, 12 LSTs, and 12 LCTs, along with a covering force led by Admiral Berkey and an escort carrier force under Rear-Admiral Thomas Sprague, facilitated the amphibious movement. Additionally, Vice-Admiral John McCain's fast carrier group provided support. Anticipating minimal resistance, the landings were planned near prospective airfield sites on the Doroeba Plain in southwest Morotai. General Hall's strategy involved the 155th and 167th Regiments landing on Red Beach on the southwestern coast to swiftly capture the abandoned Pitoe Drome and secure the new Pitoe Airfield site. Meanwhile, the 124th Regiment landed at White Beach, about 1500 yards to the south, to secure the Gila Peninsula and the Wama Airfield site. The reserve 126th Regiment was scheduled to land the following day, with its 1st Battalion initially supporting the 124th Regiment's operations at the beachhead.
Both the Palau and Morotai operations were supported by a coordinated strategic air support program. Admiral Hoover's land-based aircraft were tasked with neutralizing Japanese airfields at various islands including Yap, Woleai, Truk, Ponape, Pagan, Bonin, and Marcus Islands. Concurrently, General Kenney's Allied Air Forces reinforced these efforts and targeted enemy air centers in Palau, Mindanao, western Dutch New Guinea, Halmahera, the Talaud Islands, the Moluccas, the Celebes, and the Arafura Sea islands. Additionally, Mitscher’s fast carriers embarked on an ambitious campaign, launching strikes from the Bonin and Volcano Islands to the Palaus and Mindanao between late August and the start of the invasions.
This strike had a twofold objective: the temporary neutralization of Japanese airfields on those island groups and, more important, the creation of a diversion on the north preceding stronger attacks against targets in the Philippines and western Carolines. Carrier action in the latter area was to begin on 6 September, with strikes on the Palaus, Yap, and Ulithi. The bulk of the carrier forces was to leave the western Carolines on the afternoon of the 8th to take up positions off Mindanao. Japanese airfields on Mindanao presented difficult targets because they were scattered over that large island, but it was believed that the cluster of airfields and associated installations in the Davao area would provide profitable targets for carrier-based aircraft attacks. The Davao and Sarangani Bay areas, as well as Japanese shipping routes from Davao to Zamboanga and thence north toward Manila, were also expected to provide profitable targets. Strikes against airdromes and shipping in the Mindanao area were to be carried out on 9 and 10 September, while on the 10th and 11th part of the carrier force was to hit the Palaus and Yap-Ulithi again.
Rear-Admiral Ralph Davison’s carrier-launched aircraft struck Chichi Jima and Iwo Jima from August 31 to September 2. The Fast Carrier Task Force continued with strikes on Yap and the Palaus from September 6 to 8, and on Mindanao from September 9 to 10. Enemy air resistance was surprisingly weak throughout these operations, prompting Halsey to redirect plans for a follow-up attack on Mindanao to the Central Philippines. While the Japanese forces in the Philippines hastened to complete preparations against anticipated Allied invasion, enemy carrier-borne aircraft served sudden warning on September 9 that the date of this invasion was fast drawing near. In the first large-scale air operation by the Allies against the Philippines, an estimated 400 carrier planes staged a devastating ten-hour offensive against southern Mindanao, concentrating their attacks on Davao, Sarangani, Cagayan and Digos. Since Japanese air patrols had failed to discover the enemy task force, the attacks achieved complete surprise and inflicted widespread and severe damage to ground installations, airfields, anchorages, and lines of communication. Reconnaissance units of the 1st Air Fleet immediately flew off search missions, which revealed that the attacks originated from three enemy naval task groups boldly maneuvering in the waters southeast of Mindanao. As per the Sho-Go directives, however, the 1st Air Fleet withheld retaliatory action pending further developments. Ground and naval units in the Davao area were nevertheless ordered on the alert to meet the possible contingency that an invasion attempt would follow the air strikes, and the Japanese armed forces throughout southern Mindanao became tense with expectancy. A feeling of nervousness gripped the weak local forces at Davao and rapidly spread to the large Japanese civilian colony. A wave of wild rumors swept the city. On September 10, a second series of heavy enemy raids aggravated this state of alarm. The city and harbor were reduced to a shambles and communications paralyzed. Panic and civil disorder broke out.
Less than 48 hours after the termination of the raids on Mindanao, the enemy struck again; this time in the central Philippines. On the morning of 12 September, a navy radar picket station on Suluan Island, in Leyte Gulf, broadcast over the general air-warning net that a vast formation of enemy carrier planes was heading westward toward the Visayas. Since the Suluan Island lookout was only about twenty minutes' flying time from Cebu, the air forces there could not be alerted quickly enough to put up an effective defense. By 0920 the enemy planes were already swarming over the Cebu airfields, where the main fighter strength of the First Air Fleet was based following its transfer from Davao. Although the attacks extended over the entire Visayan area and later took in Tawitawi, in the Sulu Archipelago, the Cebu fields appeared to be the principal objective. In the three days over which this air offensive continued, the First Air Fleet suffered damage to 50 Zero fighters on Cebu alone, while in other areas 30 additional aircraft of all types were rendered non-operational. Flight personnel suffered numerous casualties, and training was disrupted. Heavy damage was also sustained by Army air units. The 13th Air Brigade, made up of Type I fighters, was so hard hit that it had to be ordered back to Japan for regrouping, while the 45th Fighterbomber Regiment was reduced to half strength. In addition, 11 transports totalling 27,000 gross tons and 13 naval combat vessels were sent to the bottom of Cebu harbor.The unexpected weakness in enemy air defenses led Nimitz to reconsider bypassing Yap and Mindanao, instead focusing forces on an early invasion of Leyte. McCain’s group continued with attacks on Zamboanga, the Talauds, and Menado en route to Morotai. Meanwhile, between September 1 and 14, Kenney’s aircraft conducted heavy raids on Japanese air bases within range of Morotai, effectively isolating the island. Targeted locations included Halmahera, the northern Celebes, Ceram, western New Guinea, and Mindanao.
After rehearsals and preparations were completed, Barbey’s convoy departed Aitape on September 9. Two days later, they rendezvoused at Maffin Bay with the majority of General Persons’ 31st Division. The entire convoy departed the area on September 12, joined the next day by the covering force and escort carriers. The voyage proceeded smoothly, and Barbey successfully reached Morotai on the morning of September 15. Meanwhile, McCain’s carrier aircraft conducted a bombing and strafing mission over Japanese air bases in the Manado area, destroying 28 enemy aircraft. Kenney’s bombers also struck Japanese air installations on Batjan Island, while Berkey’s cruisers and destroyers shelled enemy positions along Galela Bay. Barbey’s surface warships conducted a bombardment of the landing area.
During the naval and air bombardment, assault ships moved into their assigned positions west of the landing beaches efficiently and without confusion. The initial waves formed quickly and landed the 155th and 167th Regiments on Red Beach at 08:30, followed by the 124th Regiment on White Beach one minute later. Encountering no opposition, the troops swiftly reorganized on shore and advanced toward their objectives inland. By 13:00, the 167th Regiment had secured Pitoe Drome, and by 15:00, Colonel Starr’s 1st Battalion had secured Gila Peninsula. Other units also advanced inland, establishing the 2000-yard beachhead line. Although there were some minor skirmishes, the Japanese could not mount significant resistance against the overwhelming Allied force and retreated into Morotai's rugged interior. The day's action resulted in seven wounded among the 124th Regiment and the loss of twelve Japanese soldiers, with one captured.
Beach conditions, however, proved unexpectedly poor, severely hindering the unloading efforts. Consequently, starting on September 16, all the LSTs, along with numerous LCTs and LCMs, had to be unloaded at Blue Beach, a favorable landing spot on Pitoe Bay's shores. Simultaneously, as the reserve 126th Regiment was disembarking, Persons resumed advancing inland against minimal opposition. Swiftly, they secured a perimeter around the Pitoe Drome area, spanning over 7000 yards wide and approximately 5000 yards deep. Following this, American patrols were dispatched to eliminate small Japanese groups, radar stations and observation posts were established on various offshore islands and Morotai's coastline, and efforts were made to expand the perimeter to the Sabatai River to accommodate additional bivouacs and supply installations.
Leaving Morotai behind, attention shifts to Burma to explore the aftermath of Operation U-Go. Following the decisive victories at Imphal-Kohima, General Slim opted to pursue retreating Japanese forces toward the Chindwin River, despite the need for rest among his weary British-Indian divisions. Consequently, the 23rd Division spearheaded the pursuit to Tamu, at the head of the Kabaw Valley, where Major-General Charles Fowkes' 11th East African Division took over in early August. Meanwhile, to the south, General Evans' 5th Division pressed toward Tiddim, encountering stubborn resistance from General Tanaka's 33rd Division. Slim's strategy aimed for both divisions to eliminate remaining Japanese forces west of the Chindwin and converge at Kalemyo. Subsequently, the Tiddim road would be abandoned as a supply route in favor of the Kabaw Valley and aerial resupply drops.
As a result, the 31st Division, now led by Lieutenant-General Kawata Tsuchitaro, successfully reached Sittaung. Their mission was to cover the withdrawal of other units in the region. Meanwhile, the 33rd Division faced challenges as it conducted delaying actions along the Tiddim road, with the added threat of East African forces potentially cutting off their withdrawal route towards Yazagyo. Japanese delaying tactics were always the same, and the means of dealing with them was also always the same. A crater would be found beyond which the lead infantry would come under fire and would have to be filled or covered using a Valentine bridgelayer, while air strikes would break up the blocking position to allow tanks from 3rd Carabiniers forward to support them.
To disrupt Tanaka’s communications south of the road, an ad hoc light unit, the Lushai Brigade, was deployed. By mid-August, General Mutaguchi ordered his forces to commence withdrawal towards the Zibyu Range. The 15th and 31st Divisions were directed to cross the Chindwin River by August 25, despite shortages of small boats. At the beginning of the crossing operation, a serious setback was experienced. It had been planned to bring small boats upstream to the crossing area with supplies for the Army and to utilize the same boats to evacuate casualties and heavy weapons south to Kalewa. Because of the enemy air activity over the Chindwin River, it was impossible to bring the boats to the crossing points. As a result, approximately 3000 sick and wounded were forced to cross the river and continue to the rear on foot with increasingly heavy death losses.
By August 31, they were expected to reach the eastern bank of the Chindwin, with the 15th Division consolidating along the Pinbon-Pinlebu line by the end of September and the 31st Division reaching Shwebo by mid-October. By the end of August, key command changes occurred following the setbacks of Operation U-Go. Lieutenant-General Katamura Shihachi replaced General Mutaguchi as commander of the 15th Army, while Lieutenant-General Kimura Heitaro took over from General Kawabe as commander of the Burma Area Army. Kimura Heitaro, noted for his strategic flexibility and acumen, subsequently directed the 33rd Army to secure a defensive line from Lashio to Mandalay, safeguarding the right flank of the 15th Army. The 15th Army, in turn, was tasked with holding the Irrawaddy River from Mandalay to Pakkoku, while the 28th Army was assigned to defend the Yenangyaung oilfields, the Arakan coast, and the Rangoon delta.
Meanwhile, on September 12, the 33rd Division crossed the Manipur River and proceeded with their retreat towards the Kabaw valley. They left the 215th Regiment to guard the rear at Tonzang, while units of the 5th Division infiltrated the area between Tonzang and Kalemyo to disrupt Tanaka's withdrawal and mount significant attacks against the 215th. By September 20, the Japanese forces were forced back to Tiddim, where the 214th Regiment covered the retreat of the rest of the division. Simultaneously, the 26th King’s African Rifles moved east from Tamu to Sittang, crossing the Chindwin River on September 8 to assess enemy strength across the river and prepare bridgeheads for a broader crossing. Encountering unexpectedly strong resistance, they were compelled to retreat back across the river. Under persistent pressure, the Japanese evacuated Tiddim on the night of October 6. Tanaka consolidated his division in the Kalemyo-Kalewa area by the end of October, while pursuing forces captured Fort White and Kennedy Peak. On October 10, the 4th King’s African Rifles launched an assault on Leik Ridge, suffering significant casualties but ultimately securing the main hill twelve days later. Meanwhile, after withdrawing from Mogaung, the 53rd Division regrouped at Mawhun by September 10, where they successfully defended against enemy units until the end of the month. They then retreated towards Pinwe and came under the command of the 15th Army on October 5.
Following the Quebec conference in September, a strategic overview of Burma emerged: the Combined Chiefs of Staff approved two plans. The first, codenamed Dracula, proposed an amphibious assault on Rangoon with a target date of March 15, 1945. The second plan, Capital, aimed at the conquest of north and central Burma, with General Slim suggesting an overland capture of Rangoon as part of the operation. Initially skeptical, the Americans reluctantly agreed to Dracula, contingent on ensuring that northern Burma received adequate resources. However, due to Allied setbacks at Arnhem and during the Battle of the Bulge, it became clear that reinforcements from the European theater could not be spared for the Rangoon offensive. Consequently, it was announced that the operation would need to be postponed until after the 1945 monsoon season.

- 145 - Pacific War Podcast - Operation Dan 26 - August - September 2 , 1944
27 8月· The Pacific War - week by week
Last time we spoke about the battle of the Driniumor River. In July and August, American and Japanese forces clashed near Afua in New Guinea. Troop A of the 112th Cavalry engaged Japanese units, pushing them back temporarily. Troop C replaced Troop A but was soon isolated by Japanese attacks. The American TED Force, including the 124th and 169th Infantry, launched a counteroffensive, facing heavy resistance. Despite supply and terrain challenges, TED Force advanced, forcing the Japanese to gradually withdraw. By early August, the Japanese launched fierce and desperate attacks, but American defenses held firm. TED Force continued its advance, encountering further fierce Japanese resistance but successfully disrupting their supply lines. The Japanese, suffering heavy losses, were finally forced to begin a general retreat, as the American forces consolidated their positions by early August. It seemed Green Hell was still living up to its dreadful nickname.
This episode is Operation Dan

This week we are picking up with the action along the CBI theater. In Yunnan, by the end of July, General Wei's Y Force was still engaged in efforts to eliminate the resilient but small Japanese garrisons at Tengchong, Mount Song, Pingda, and Longling. Simultaneously, the 33rd Army was striving to accelerate preparations for Operation Dan, anticipating resistance from General Honda's main garrisons until September's end. Following the fall of Myitkyina in August, Honda recognized the need to expedite his offensive plans, despite delays in the deployment of the 2nd and 18th Divisions. Additional reinforcements from the 49th Division were expected in Mandalay by September, bolstering Honda's position. Meanwhile, General Matsuyama faced the challenge of isolated garrisons cut off from his 56th Division, surrounded by superior enemy forces. With his main forces focused on imminent offensive preparations, Matsuyama could only provide moral support through radio messages. Colonel Matsui's recent successes reduced Chinese activity on the Mangshi front, allowing for the rehabilitation of the 113th Regiment by August, despite occasional small-scale raids. At Tengchong, Colonel Kurashige resolved to defend the Walled City to the last man against relentless infantry assaults, air bombardments, and continuous enemy artillery preparations.
Compared with the defenses of Lameng, the positions at Tengchong were much less effective due to the factors of disadvantageous terrain and the lack of time to make defense preparations. Tengchong Castle covered an area slightly over a half-mile square; and was surrounded by a rampart 16 to 20 feet in height and over six feet thick at the top. Although the rampart had a stone facing and was backed with clay, it was not proof against an artillery bombardment and considerable work was required to strengthen it. Concrete or stone pillboxes were constructed adjacent to all gates and at the four corners. Shelters were built to protect guns and machine guns mounted on the rampart as well as for the troops and supplies inside the wall. Other entrenchments were prepared within the castle itself. While these measures greatly strengthened the defenses, the castle was still not proof against an intensive air or artillery bombardment. Recognizing the southeast as the primary avenue of approach, General Huo directed his forces to concentrate their main efforts in that direction.
On August 2, following another bombing raid by twelve B-25s that created a gap fifteen feet wide, the 36th and 116th Divisions initiated a new general assault. The Japanese quickly worked to repair the breach and fired machine guns to cover it. It was only after concentrating guns, rockets, and flamethrowers on the southwest pillbox, along with five waves of fighter cover fire, that the Chinese were able to position scaling ladders against the wall. Two companies then seized the top of the wall just east of the southern corner on August 3. Overnight, Kurashige led a successful counterattack that restored defenses along the rampart, except for one platoon that held its ground all night. This platoon's resilience allowed Chinese reinforcements to pass through the breach on August 4 and seize a pillbox inside the city. With the walls breached, the fall of Tengchong became inevitable, but the determined defenders continued to resist fiercely in the coming days, inflicting heavy casualties on the Chinese attackers. Meanwhile, Major Kanemitsu’s Lameng Garrison defended Moung Song fiercely. After the Hondo Position fell, the 308th Regiment resumed the advance on 3 August it had flamethrowers which it used with devastating effect to take the crest of Kung Lung-po. There the Chinese found several Japanese tankettes, which had been dug in for use as pillboxes. Despite repelling enemy attacks with great effort, the Japanese faced dangerously low ammunition supplies. As a result, Kanemitsu decided to raid the 8th Army's artillery positions and supply dumps to replenish his ammunition stocks. Twenty-nine men, selected from the artillery battalion, were divided into two teams for the purpose. One team was to raid the artillery positions on Shirakabe and Haraguchi Hills as well as to attack motor vehicles on the road between Lameng and Huitung Bridge. The second team was to operate in the area to the south and west of the Gake and Hondo Positions.
On the night of August 9, seven groups of Japanese volunteers launched a surprise attack, destroying several howitzers and seizing light weapons and ammunition. Despite Kanemitsu’s initial success and his troops' resilient defense against Chinese infantry assaults, General Song opted to revert to conventional siege tactics starting August 11. His divisions began digging tunnels beneath key Japanese strongholds in the Mount Song triangle, each tunnel stretching 22 feet to accommodate two powerful mines aimed at enemy pillboxes.One mine held 2,500 pounds of TNT, the other mine held 3,500 pounds of TNT. The mines detonated on August 20, causing significant damage that engineers exploited swiftly with flamethrowers, capturing Kanemitsu’s primary stronghold. In one pillbox forty-two Japanese were buried alive, of whom five were rescued. The prisoners stated that they had been asleep and had never suspected that they were being undermined. At 0920 the 3d Regiment against light opposition took the few strongpoints that remained on Sung Shan proper. In spite of particularly heavy pressure being exerted against the Sekiyama Position, the enemy had made little progress. However, on 19 August, following a heavy bombardment three tremendous blasts shook the Sekiyama Position. The Chinese, becoming discouraged with trying to storm the position, had tunneled under it, the defenders of the Sekiyama Position were virtually annihilated and the position fell to the enemy. On 23 August the Lameng Garrison regrouped to make final resist- ance in the Otobeyama, Nishiyama, Matsuyama, Yokomata and Urayama Po- sitions. The total number available for defense had been reduced to about 150 men, all of whom were wounded, some seriously. Even those who had lost an arm or a leg were propped up in positions where they could fire a rifle or sight a gun. The Lameng Garrison continued to resist in scattered pockets, launching futile counterattacks, Song recognized the battle's turning point.
During the latter part of July and early August, the Yunnan Force made new troop dispositions and moved in three divisions to attack the town. The main force of the Chinese 87th Division was on the east front, with an element along the Tien-Mien Road; the New 28th Division was between the two elements of the 87th; elements of the 1st Honor Division were on the north front with the New 39th Division on the south and west of Longling. At dawn on 14 August, preceded by an intense concentration of artillery fire and air bombardment, the Chinese forces launched a coordinated attack from all sides. Hill 6 bore the brunt of the enemy attack for eight hours but managed to hold, as did the defenders on the main line of resistance. After the attack had ceased, the Garrison spent the entire night rebuilding defenses, using rubble and half-burned mate- rial from the town. However, five days later, Chinese forces captured the eastern hills, weakening the entire Japanese defensive line. Consequently, by August 23, the eastern front collapsed, compelling the Japanese to retreat from their main defensive positions to reserve positions within the town.
Matsuyama was aware that under the current conditions, Longling would likely fall before September began. While the timely reinforcement of the 3rd Battalion, 148th Regiment would enable the garrison to hold out for a few more days, he understood the urgency of accelerating the Dan offensive to relieve Longling. Starting on 26 August, the 2nd Division began moving from Namhkam to Mangshih under cover of darkness, requiring three nights to complete the movement. Shortly thereafter, the headquarters of the 16th Regiment was called from Bhamo to Mangshih and Col. Hara Yoshimi, commanding officer of the 2nd Reconnaissance Regiment, succeeded Col. Sakai as commander of the Bhamo Garrison, which was placed under 18th Division control. On 30 August, the Division conducted a war game followed by a conference to brief subordinate commanders on the plans and missions of the Dan Operation.
With the recent arrival of the 4th and 146th Regiments, Matsuyama planned to send Matsui’s Task Force and the 146th Regiment northwestward to clear the western sector. Meanwhile, General Okazaki’s 2nd Division would attack northeastward to defeat the main enemy force in the eastern sector, thus fully relieving Longling. Subsequently, the 56th Division would advance towards Tengchong, while the 2nd Division moved towards Lameng, to relieve both isolated garrisons. However, before this offensive could begin, new developments emerged from Tengchong. Realizing that assaults on the ramparts were too costly, Huo ordered his Chinese troops to start tunneling under the walls. Additionally, air attacks increased in intensity, and on August 13, several large bombs struck the headquarters, killing Kurashige and leaving the garrison nearly leaderless. The following morning, after a heavy artillery bombardment of about 20,000 rounds, Huo launched his second general attack.
Despite the garrison's determined defense against Chinese attempts to breach or scale the ramparts, Huo reinforced his southern assault with the 198th Division, applying intense pressure. While defenders held against the combined attacks of more than two divisions, the 198th Division, which had made several ineffectual attacks in the northwestern sectors, was brought south to reinforce the units already there. Three divisions pitted against the badly damaged southern wall could not be held off and Chinese troops began infiltrating beyond the rampart. The garrison launched successive counterattacks and, while they were successful in driving the enemy out on the first two occasions, the third counterattack so exhausted the defenders that the enemy held the southwest corner of the compound. The Chinese were not, however, able to make any appreciable headway in breaching any other part of the castle's defenses.
Three days later, following another heavy air and artillery bombardment that succeeded in making seven breaches in the southern rampart, the Chinese resumed the offensive and managed to force the garrison to relinquish all but the southeast corner of the southern part of the castle compound. On August 22, a fourth attack was then launched; and, in spite of valiant efforts by the defenders, the west gate of the castle was finally taken by the 198th Division early in the morning of August 24. The following day, about 500 grenades and medical supplies were dropped by 12 Japanese fighters, which bolstered the garrison’s morale even though their fate was pretty much sealed already.
Simultaneously, Matsuyama initiated Operation Dan on August 26, with Matsui’s Task Force struggling for six days to secure control of Komatsu Hill before advancing towards Shuangpo on September 1. The Dan Offensive opened inauspiciously with an unsuccessful attack on Komatsu Hill, about three miles south of Lungling. Launched by the 1st Battalion, of the 113th Infantry (Takeda Battalion), on the morning of the 26th, the attack was thrown back and it was not until the following morning after the 3d Battalion, of the 113th (Murakami Battalion) had been thrown into the attack that the Takeda Battalion succeeded in seizing the western half of the hill. Upon achieving the objective, the Murakami Battalion was withdrawn and the Takeda Battalion was exposed to severe counterattacks which the enemy repeated for four days. The Takeda Battalion sustained extremely heavy losses, including the loss of three company commanders. The Inose Battalion attacked the hill from the northeast on 30 August and succeeded in making contact with the Takeda Battalion the following day but the northern part of the hill still remained in the possession of the enemy. Unable to hold up the advance any longer, the Inose Battalion was left at Komatsu Hill to clean out the remnants of the enemy and the main body of the Matsui Column advanced to Shuangpo on 1 September, fighting their way through enemy resistance.
The 146th Regiment successfully bypassed Chinese forces blocking the Tien-Mien Road, reaching the ridge west of Shuangpo. The 113th and 146th Regiments continued their northwestward advance, reaching the Longling River line by September 6, where they nearly wiped out the New 39th Division. Meanwhile, Okazaki assembled his 4th, 16th, and 29th Regiments at Shuangpo, preparing for an offensive. To the south, the 76th Division persisted in defending Komatsu Hill despite heavy casualties. Okazaki directed the 4th Regiment to attack the enemy’s northern positions on September 3, resulting in repeated assaults over the next three days. Despite suffering significant losses, the Japanese were compelled to halt their local offensive.
In the meantime, the 16th and 29th Regiments moved northeastward. The 29th Regiment successfully breached enemy positions and linked up with the besieged garrison by September 6. Despite this victory at Longling, subsequent events at Mount Song and Tengchong rendered Operation Dan futile. On August 29, following the fall of the Otobeyama Position, Kanemitsu realized that resistance could only last a few more days. On September 5 Major Kanemitsu sent to the commander of the 56th Division a final radio message: “All of my brave officers and men have determinedly defended our position for 120 days since May 10 with a sublime spirit of self-sacrifice and an attitude of absolute obedience. However, our ammunition has been entirely expended and practically every officer and man is wounded. The final moment has come. We will burn the colors and code books and make a suicide stand with what strength remains. I do not have the words to apologize for the fact that, because of my unresourceful command, we have been unable to hold out as long as expected. We are deeply moved by your long and special consideration of our situation. I respectfully ask that everything possible be done for the bereaved families of the officers and men of the Lameng Garrison. Our souls will continue to pray for the eternal prosperity of the Imperial Throne and the final victory of the Japanese Forces.”
Consequently, on September 5, he concentrated his remaining forces in the northernmost positions, which came under heavy enemy fire the next day. After Kanemitsu's death from a mortar shell, the Japanese burned their colors and euthanized their wounded. They launched a final suicide charge on September 7, resulting in the death of the remaining 50 survivors. Of the 1260 Japanese at Lameng Garrison, only 9 were captured and 10 believed to have escaped, with the rest perishing at the hands of Song's divisions, totaling approximately 41,675 troops. The significance of Mount Song lies in the four-month siege to clear the block from the Burma Road, during which the Chinese suffered 7675 casualties, including around 5000 from the 8th Army, leaving it with only two understrength regiments fit for further combat at Longling. Meanwhile, on August 31, Huo's fifth attack pressed with great enthusiasm, eventually succeeding in taking the southeast corner, which had withstood the onslaught of two divisions for over a month. The garrison was then pressed back to a line running from the east gate through the center of the palace grounds to the northwest corner of the castle grounds. The number of survivors had been reduced to approximately 350, virtually all of whom were wounded. Five days later, the Chinese attacked once again, successfully effecting a breakthrough of the defensive line which split the defending force into two groups. By September 9, the northwest corner had been completely overrun and only 70 men remained to hold the northeast corner. Realizing that the end was near, the Japanese burned their colors and on September 14 launched a last suicide charge in which the remainder of the garrison was finally cut down.
In a valiant defense, rivaling that of the Lameng Garrison, the 2025 men of the Tengchong Garrison held off the Chinese 20th Army, numbering an estimated 50,000 troops, for approximately 80 days. Despite this, the capture of Tengchong marked a significant victory for Y Force, as it opened a viable route to Myitkyina known as the "Tengchong cut-off". Moreover, the fall of Tengchong and Lameng allowed the Chinese to deploy more troops to counter the Dan offensive. In the early hours of September 7, the 113th and 146th Regiments crossed the Longling River and launched an assault on the 1st Honor Division, entrenched in strong defensive positions. Although General Matsui’s battalions were repelled by determined defenders, the 146th Regiment made notable progress on the left, gradually pushing the Chinese forces northward. By September 9, the western and northern sectors had been partially cleared, and the Longling Garrison was nearly completely relieved. Simultaneously, the 29th Regiment, supported by remnants of the 16th Regiment and the 2nd Field Artillery Regiment, advanced northeast towards the eastern hills, encountering difficulty in capturing them. By September 9, they had only secured one of the hills. With Honda growing impatient due to the slow progress of the 2nd Division. Okazaki directed increased attacks in the following days. An attack was launched on 11 September but did not succeed. Then an attack conducted on the 12th, y the 3d Battalion, 29th Infantry was successful in seizing the hill, however a counterattack by the enemy resulted in the annihilation of the Battalion and the retaking of the hill by the Chinese.
Furthermore, Okazaki also noted that the Chinese were still holding their ground to the south. Consequently, orders were issued for the 1st Battalion, 16th Regiment to address this lingering threat. However, the battalion exhibited such limited initiative that Colonel Tsuji Masanobu of the 33rd Army staff assumed direct command of the frontline units. With the addition of another battalion, this proactive commander led his troops in a series of vigorous assaults, culminating in the capture of the southern hill by September 15. Meanwhile, to the north, Matsuyama successfully relieved Longling, yet a new challenge emerged. The formidable 200th Division had arrived from Kunming and launched immediate attacks against the 113th and 146th Regiments by September 9. Fortunately, Matsuyama received reinforcements in the form of the 3rd Battalion, 148th Regiment and the reserve 168th Regiment, effectively clearing the northern sector by September 11. Positioned defensively, Matsuyama’s forces continued to fend off repeated counterattacks from the aggressive 200th Division, while the 168th Regiment moved westward to confront a significant element of the 36th Division advancing south from Tengchong. At this juncture, the Japanese had suffered approximately 1800 killed and 2500 wounded, while Honda estimated inflicting over 63,000 casualties since May. Despite the costly relief of Longling by mid-September, the 33rd Army had failed to reach the Nu Chiang River or rescue the Lameng or Tengchong Garrisons. Moreover, with Tengchong's fall, the entire 20th Army Group was mobilizing to reinforce Chinese forces engaged in the Longling campaign.
Realizing that Operation Dan faced inevitable failure, Honda opted to halt the offensive. Instead, he directed the 2nd Division to undertake a defensive stance south of Longling. Simultaneously, the 56th Division and the 168th Regiment disengaged from the enemy, moving southwards to relieve the Pingda Garrison. On September 16, the divisions rotated smoothly: the 56th Division gathered east of Mangshi, while Colonel Yoshida Shiro’s 168th Regiment initiated a covering attack to the east. This left the Longling Garrison vulnerable, prompting its commander to defy Honda’s orders and withdraw during the night. Lt. Col. Komuro's action came as a shock to Army and Division headquarters and, although he later committed suicide to atone for his act, the commander and the Garrison were considered to have disgraced themselves and the Japanese Army. Lt. Col. Nagai, a staff officer of the 56th Division, when questioned in 1959 made the following statement: "The Longling Garrison had twice before made great and courageous stands against tremendous odds. They were all exhausted by their efforts and had expected to be relieved. It is understandable that the Garrison should bitterly resent being placed in a position where they might possibly be surrounded in Longling a third time. The defense line of the 2nd Division was so drawn as to leave Longling projecting and constituting a primary target for enemy attacks. It should also be borne in mind that the Garrison was not an organic unit but was, instead, a composite group composed of various elements without the esprit de corps of a regular unit. Although Lt. Col. Komuro was a respected officer, his tendency toward a philosophical approach to life may have made it impossible for him to hold out against the unanimous discontent and resentment of his subordinates."
Fortunately, Matsui’s 3rd Battalion arrived in Longling two days later without encountering Chinese forces. Despite being outnumbered, the 2nd Division managed to maintain its extended front by destabilizing the enemy and conducting nightly raids. On September 17, Matsui launched a successful relief operation, driving the 9th Division from the Sahngzhai area. Concurrently, the 146th Regiment embarked on a forced march towards Pingda; by September 22, it breached the enemy lines, reaching the besieged city. Having been isolated for nearly six months, there were scenes of wild rejoicing as the besieged Garrison welcomed the Imaoka Column. Carrying about 150 casualties on stretchers the combined forces of the Imaoka Column and the Pingka Garrison broke through the enemy lines at night and, on the 24th, reached Liangtzuchai where they were covered by the Matsui Column. Both units withdrew to Mangshih and, when the Yoshida Force subsequently pulled back from Isao Hill, the Pingka relief operation was concluded. Following the conclusion of the Pingda relief operation, Honda began preparations for the impending enemy offensive.
Subsequently, the 56th Division was tasked again with defending Longling and Mangshi, while the 2nd Division relocated to Muse to prepare for a potential counterattack in the Shweli River valley. Meanwhile, the rested and reorganized 18th Division, now under Lieutenant-General Naka Eitaro, successfully concentrated at Namhkam by the end of September. The 33d Army expected that the main force would arrive prior to the end of the month, but the movement was executed very slowly and units were arriving in Namhkan throughout the month of September. Upon arrival of the Division at Namhkan, the units continued the work on fortification construction that had been started by the 2d Division. The main body of the Division moved via rail through Mandalay, while the 55th Infantry Regiment, with one artillery battalion and one engineer company advanced through Katha, Kunchaung and Sikaw on foot. The Division was gradually built up and, by the end of September, had achieved a strength of about 7,000 men. Since the replacements for the most part consisted of men recently discharged from hospitals, the complete recovery of the Division was understandably slow. The 18th Division finally managed to concentrate in Namhkam by 1 the early part of October. On 2 October, when Lt. Gen. Naka, who was replacing Lt. Gen. Tanaka, arrived at Namhkam, he found that the Division still had not fully recovered from the effects of the Hukawng Operation. However, abundant food supplies in the area, combined with excellent climate, enabled the division to make an unexpectedly rapid recovery during the month of October. By early November, the strength of the Division had been built up to about 9,000 men of whom about 3,000 were reinforcements from Japan. Some tanks and two 149-mm howitzers had been supplied and six mountain guns repaired. During this period of rehabilitation the Division engaged in the construction of defense positions on both sides of the Shweli River in the general area of Namhkam.
This period allowed the Japanese ample time to strengthen their defenses, as Y Force had suffered significant casualties. General Wei found it necessary to retrain and reorganize his depleted divisions before resuming the offensive in Yunnan. Because all of his immediate reserves had been drawn into the fight for Longling, and considering that the Chinese Government had ignored his earlier pleas, Wei Lihuang asked General Dorn, chief of staff of the American personnel working with Y-Force, to present his further requests for 20000 trained replacements (Wei had not received one since the offensive began); for two more divisions; for permission to use the 5th Army's tank battalion; and for Baoshan to be developed as a supply base. Dorn, however, was only partially successful in that the National Military Council renewed its promises to send replacements.
Shifting focus from Yunnan, we turn to the new operations of the 20th Bomber Command. Following the unsuccessful Yawata strike on August 20, Saunders continued planning for the return to Anshan, initially set for August 30 but postponed to September 8. On August 29, Major-General Curtis LeMay assumed command of the 20th Bomber Command. Despite the change in leadership, Saunders' plan remained unchanged: to deploy every serviceable B-29 aircraft. Saunders’ plan was to dispatch every B-29 fit to fly; and so, by September 8, 115 bombers had gathered in the forward area and 108 successfully got off the runways. Of these, 95 reached Anshan to find good weather, with 90 of them dropping 206.5 tons of bombs at the Showa works and 3 bombing other installations while another 5 hit the Xinxiang Railroad Yards and 3 others hit various targets of opportunity. Total losses for the mission were four: a crack-up near Dudhkundi on the way up; two forced landings in China, one destroyed on the ground by enemy planes and one partly salvaged; and a plane listed as missing. The crew of this last plane later walked out with the loss of only one man. The Americans in turn claimed 8 kills, 9 probables and 10 damaged.
The following day, a B-29 reconnaissance plane reported significant damage to the steelworks. Out of the sixteen coke oven batteries, three were estimated to be out of commission for a year, and another three for six months. Additional damage to related installations and the byproducts plant further compounded the impact. Overall, command intelligence officers calculated that the two attacks had reduced Showa's coking output by 35.2%, which in turn would decrease total Japanese rolled steel production by 9.3%. In response to the extensive damage, the Japanese launched their first counterattack against the 20th Bomber Command. Shortly after midnight, Japanese bombers came over Xinjin and attacked the American headquarters, storage areas, and the parked B-29s. Aided apparently by ground signals, the intruders made four runs, dropping fragmentation and high explosive bombs to inflict minor damage on one Superfortress and a C-46, and to wound two soldiers.
Meanwhile, LeMay, who had accompanied the mission to Anshan, was encouraged by the promising results. Despite this, he had been tasked with implementing significant changes to the command. He began revising tactics, tightening and expanding formations, and enhancing training for greater bombing precision—effects that would become evident in the following months. Specifically, LeMay intended to substitute for the current 4-plane diamond formation a 12-plane formation similar to one he had used with his heavies in the ETO. He proposed further to follow 8th Air Force practice by subordinating night missions, so far numbering four of the command’s eight strikes, to daylight precision attacks. This would not mean the abandonment of radar bombing, so vital in variable weather. LeMay’s doctrine called for “synchronous bombing” in which both the bombardier and radar operator followed the bomb run in, with visibility determining who would control the plane during the crucial seconds before release. Precision bombing required training more sustained than the sporadic sessions which the command’s crews had undergone, and fortunately new arrangements for nourishing strikes out of China would release B-29s and their crews from much of the Hump transport duty which had handicapped training. On September 5 LeMay had ordered each group to select 6 lead crews (later increased to 8) upon which other crews in a formation would drop. A week later a school was set up at Dudhkundi, occupied since early July by the 444th Group. Ground training and a simulated mission and critique on each of 10 successive days made the 11-day course at “Dudhkundi Tech” both strenuous and valuable. Meanwhile, the other crews of the 4 combat groups had been working with the 12-plane formation and had made some progress when training was interrupted for the ninth mission.
Most of September was spent initiating LeMay’s reforms, leaving time for only one major operation at the end of the month. Consequently, LeMay decided to finish off Anshan with another 100-plane strike. By September 26, he consequently had 117 B-29s forward, with 109 of them successfully getting airborne the following morning. Though take off had been improved since the last mission, bad weather and a cold front would see only 86 bombers reaching Anshan; 73 of them actually bombing the Showa works, all by radar. Subsequent photographic coverage, however, indicated absolutely no new darnage. In addition, two B-29s bombed Dairen, four Xinxiang, and nine bombed various targets of opportunity. Japanese opposition was likewise ineffective, with the Americans suffering no losses. but during the night, enemy bombers managed to sweep into the Chengdu area to drop three strings of bombs and damage five bombers, two of them seriously. The Chinese warning net had tracked the Japanese planes in from Hankow airfields and the 317th Fighter Control Squadron at Chengtu had ample time to alert command personnel. But the one P-47 up could not make contact. The 312th Wing had suffered with other China-based units from lack of supplies, and in the interest of economy of fuel one of its P-47 groups had been exchanged for the 311th Fighter Group, equipped with P-51B’s. Chennault, reluctant to tie down two full groups for the static defense of Chengtu, had disposed part of the wing forward where the planes could take a more active part in the war, and events were to prove that this policy constituted no serious danger to the B-29 fields.

By mid-September, intense battles in the CBI theater saw the Japanese forces grappling with diminishing supplies and overwhelming Chinese offensives. Despite heroic defenses at Tengchong and Lameng, Japanese positions fell after heavy casualties and strategic missteps. General Matsuyama's relief efforts at Longling achieved temporary success, yet the broader objectives of Operation Dan were unmet, marking a turning point in the campaign.

- 144 - Pacific War Podcast - Battle of the Driniumor River 19 - August - 26, 1944
20 8月· The Pacific War - week by week
Last time we spoke about the fall of Myitkyina. By late July 1944, the Japanese at Myitkyina in northern Burma were facing severe challenges. Despite holding out through a long siege, they were cut off from supplies and suffering heavy casualties. A leadership conflict between Colonel Maruyama and General Minakami further complicated things. Maruyama defended the city intensely, while Minakami aimed to deny Allied access to strategic roads. With depleted forces, including wounded troops trying to escape via the Irrawaddy River, the Japanese defense weakened. Allied forces, reinforced and ready, made significant gains, shrinking Japanese-held areas. On August 1, Minakami agreed to withdraw, and the remaining Japanese began escaping across the river. The Allies launched a final attack, securing Myitkyina on August 3. The 10 week siege resulted in substantial casualties on both sides. This victory allowed the Allies to improve logistical routes and marked a critical point in the Burma campaign.
This episode is the Battle of the Driniumor River

Last time we were seeing action kick up at the Driniumor River. While the Japanese offensive had initially been successful, General Hall's forces managed to halt the enemy advance and reform their river line by July 15, despite a 1500-yard gap in the center. The Japanese were aware of this weakness in the American lines and exploited it, especially during the night. However, Colonel Starr's 3rd Battalion patrolled this area and occasionally engaged the enemy, killing 135 Japanese on the night of July 14. Despite this, General Cunningham claimed that his South Force had extended its lines nearly 1000 yards beyond its assigned sector without encountering any elements of the 124th Regiment. Consequently, on July 15, Starr concluded that his regiment had not advanced as far south as previously reported and ordered his units to adjust their lines southward and extend their defenses up the Driniumor towards Cunningham's Troop E. The following morning, Starr's 3rd Battalion began moving south to close the gap. As they reached the area by nightfall, Troop E was attacked by two companies of the 1st Battalion, 239th Regiment. While the cavalrymen sought cover, Starr's 3rd Battalion was also attacked by Colonel Nara's 3rd Battalion, which had turned south after its defeat at the Paup villages. This split the American forces in two, with Companies L and M pushing south through increasing opposition to reach South Force lines, while Companies I and K dug in for the night in their current positions. Despite the intense fighting, several Japanese were killed, and the gap was reduced to 500 yards.
In the course of the day's fighting the Coastal Attack Force had lost all its artillery and had suffered heavy casualties. Additional losses were sustained on succeeding days, but Major Hoshino and his men were not completely removed as an irritant until the night of 16-17 July. During that night remnants of the Coastal Attack Force, about thirty-five men strong, attacked North Force and 124th Infantry command post installations at Anamo. At 23:00 the group charged out of the jungle southwest of the Anamo perimeter. Repulsed by machine gun fire, the enemy temporarily disappeared, only to reappear at 03:00 on 17 July moving west against Anamo along the beach. Machine gun fire from the American positions broke up this second attack, but about ten minutes later the Japanese tried again, this time moving on Anamo from the north by wading in from the sea. Once ashore, Major Hoshino's men broke up into small groups, attempting to destroy mechanized equipment, automatic weapons positions, and communications installations. The Coastal Attack Force remnants had apparently scouted well, for they were reported to have moved purposefully toward the most important installations and they easily found their way about in terrain they had vacated only four days previously. Whatever Major Hoshino's plans were, they were not realized. About forty of his men were killed and the rest dispersed.
Behind them, Hall dispatched Colonel Howe’s 1st and 2nd Battalions to clear the remaining enemy units west of the Driniumor River. Over two days of complex and sometimes uncoordinated company actions, the Americans successfully overran Nara’s stragglers in the area. Further south, as Japanese troops were seen crossing the Driniumor at a fording point about 2,500 yards south of Afua, Cunningham sent Troop A south to high ground behind the Driniumor to halt the Japanese movements westwards. There, the 78th and 80th Regiments, under Major-General Miyake Sadahiko, were assembling for a renewed offensive. Adachi’s new plan involved Miyake striking Afua from the south while the 239th Regiment prepared to move against the Kawanaka Shima area. Additionally, the retreating 237th Regiment and the reserve 66th Regiment were ordered south to join future attacks by the 20th Division, though they wouldn’t arrive until July 25. As the Miyake Force maneuvered into position to the right and rear of Cunningham’s 1st Squadron, Starr struggled to close the gap in the center, which was eventually sealed on the morning of July 18. That night, Miyake launched an attack with two battalions on the 1st Squadron's command post and the adjacent perimeter held by Troop A, successfully pushing them 250 yards to the northeast.
Early in the afternoon of 19 July fresh Japanese units began to surround the Troop A position, moving in from the north, northwest, west, and southwest. The 1st Squadron commander called for artillery fire to break up this enemy maneuver. Upon cessation of the fire, Troop A attacked to the south and west for a second time. Driving at least a company of Japanese before it, the troop pushed 600 yards southwest of its original positions astride the Afua-Palauru trail and temporarily disrupted enemy plans to seize the position. About 140 Japanese had been killed during the two days' operation around Troop A. South Force, at the same time, lost 8 men killed and 29 wounded, all from the 1st Squadron, 112th Cavalry. There were strong indications that more attacks might occur in the 1st Squadron area, but Troop A was not destined to take part in any of these actions. It was replaced on the 21st by Troop C.
Following this victory on July 21, Troop C relieved the battered Troop A, Howe’s battalions successfully set up a patrol base on the East Branch of Koronal Creek, and Starr’s 2nd Battalion moved to Palauru to provide additional outer security southwest of the airfield. On July 19, the first elements of General Wing’s 43rd Division began landing at Aitape, with the 2nd Battalion, 169th Regiment subsequently taking over about 1,000 yards of the river line on the right of the 124th Regiment by July 22. Meanwhile, Adachi ordered the still-reorganizing Miyake Force to attack Afua from the north and west while General Nakai’s 79th Regiment crossed the Driniumor and attacked from the south. On the evening of July 21, Miyake launched his attack on Troop C’s position, successfully cutting it off from the rest of South Force. While the cavalrymen resisted heavy Japanese attacks, Miyake’s units also repelled Cunningham’s attempts to relieve the beleaguered troop over the next few days. Not knowing what other plans the Japanese might have in mind, General Cunningham was unwilling to pull any more troops away from the river defenses. Moreover, he now considered the position of his right flank untenable. He therefore withdrew Troop B north of Afua about 1,000 yards and used the unit to form a new defense line which ran westward about 500 yards from Troop A's right flank, anchored on the Driniumor. South Force's right flank was now refused and additional protection had been secured for medical, supply, and command post installations at the dropping ground banana patch. Troop C was left isolated behind Japanese lines, and Afua was again released to the enemy.
It was not until the night of 21-22 July that the Japanese forward units were able to organize for any sort of attack. During that night, elements of the 124th Infantry received considerable mortar, machine gun, and rifle fire from east of the Driniumor. This fire increased the next morning, and about noon the 3d Battalion, 124th Infantry, was attacked from the west by elements of the 237th Infantry. The first Japanese attack was ". . . finally broken up by a bayonet charge . . ." conducted by elements of the 3d Battalion, 124th Infantry, but other attacks followed as troops of the 1st Battalion, 239th Infantry, tried to move across the Driniumor from the east, striking both the 124th Infantry's unit and part of the 2d Battalion, 169th Infantry. Before dark on the 22d, the 3d Battalion, 124th Infantry, counted 155 new Japanese dead in its area. That unit and the 2d Battalion, 169th Infantry, reported their own losses as five killed and twenty-five wounded.
The 1st Battalion, 239th Regiment made further unsuccessful attempts to reopen the river crossing. By July 25, Adachi decided to send the 41st Division south to assist in the southern effort. After the fall of Afua, Hall ordered Howe’s battalions to leave their East Branch base and reinforce Cunningham’s South Force, arriving at the new line by July 23. With these reinforcements, Cunningham decided early in the afternoon to send Troops A and B to attack west toward Troop C while Howe’s 2nd Battalion pushed southeast toward the isolated troop. Despite being uncoordinated, the infantry successfully moved into Troop C's perimeter from the northwest and helped repel a heavy Japanese attack from the southwest, while the cavalry troops reoccupied Afua and established new defensive positions. However, American attempts to break out on July 24 were unsuccessful due to the Japanese defending all tracks, trails, and ridgelines in the heavily jungled ground northeast of the perimeter. On July 25, Howe’s Companies E and B unexpectedly established contact about 500 yards north of the besieged forces against light resistance, allowing the battered Troop C to withdraw. With Troop C relieved, Howe’s units continued to attack south and west towards the Afua-Palauru trail, successfully pushing the Japanese into the Torricelli Mountains.
Many Japanese troops remained positioned in a triangular area bounded by the dropping ground, Afua, and Company G's ridgeline position, where they continued to harass Cunningham’s forces. Rifle fire, intensifying as darkness approached, harassed the rear and right flank of the two battalions, and the Japanese began intermittently to drop light artillery or mortar shells into the banana patch area, where the command posts of South Force, the 112th Cavalry, and the 127th Infantry were now located. Finally, Japanese patrols, coming in from the west, had scouted the banana patch area during the day, action which seemed to presage an enemy attack during the night. To get out of range of the enemy fire and danger of enemy attack, General Cunningham moved the command post installations 500 yards to the north before dark. Additionally, 127th Infantry patrols had found a Japanese map which indicated that the 66th Infantry, 51st Division, was concentrating in the Kwamagnirk area. Indeed, the 66th Infantry, which, with attached units, was at least 1,000 men strong, had crossed the Driniumor on or about 24 July. Bypassing the right flank of South Force, the regiment had moved into the heavily jungled high ground west of the banana patch and dropping ground. In addition, the remnants of the 237th Infantry, probably about 300 men strong, had finally arrived in the Afua area on 25 July and had passed to the control of the Miyake Force. Rear elements of the 20th Division, including additional men from the 26th Field Artillery and engineer units, had also crossed the Driniumor south of Afua. The number of Japanese troops in the South Force area by nightfall on the 26th of July was at least 2,500 and may have been over 3,000.
On July 27, the battalion launched a successful southward attack, but ongoing Japanese movements to the west eventually necessitated an American withdrawal, despite other units under Cunningham managing to repel enemy advances. The following day, Cunningham consolidated his positions to bolster defenses in anticipation of potential large-scale Japanese assaults. However, on July 29, efforts by the 1st Squadron and the 2nd Battalion to attack south and west into the Triangle were thwarted by determined Japanese defenders led by Adachi. As a result, only localized patrol actions were conducted on July 30 and 31, as Cunningham devised plans for another offensive into the Triangle.
Major combat activity revolved around the withdrawal of Company G, 127th Infantry, from its exposed outpost west of Afua. On the afternoon of the 29th the unit had been driven more than 400 yards east of its original position by Japanese attacks and had established new defenses on high ground about 300 yards west of Afua. On the 30th the company was surrounded and spent all day fighting off a series of small-scale attacks. The next morning it fought its way north to the dropping ground, where it arrived about 1330. Thence, it moved on to the Driniumor and joined the rest of the 2d Battalion, 127th Infantry, which had switched positions with the 3d Battalion. During the period from 13 to 31 July, South Force had suffered almost 1,000 casualties, of which 260 had been incurred by the 112th Cavalry. For the understrength cavalry regiment, this was a casualty rate of over 17 percent. The 2d Battalion, 127th Infantry, had also lost heavily and was in need of rest, reorganization, and re-equipment--needs which had prompted General Cunningham to change the places of the 2d and 3d Battalions, 127th Infantry. South Force casualties were as follows: 106 killed, 386 wounded, 18 missing, and 426 evacuated as a result of disease and sickness. South Force estimated that it had killed over 700 Japanese. By the end of July, with the arrival of most of the 41st Division, Adachi believed he had amassed enough reinforcements near Afua to launch a final offensive.
The 238th Regiment, the 41st Mountain Artillery, and the 8th Independent Engineers were across the river in time by the 30th but the 2nd and 3rd Battalions, 239th Regiment, had missed the crossing point on the Driniumor and were lost. Fortunately for the 18th Army, the South Force withdrawals on July 29 and 30 gave the 20th and 41st Divisions time to complete their organization. New orders were issued for the attack to start on August 1, with the 20th Division on the west and the 41st Division on the east. The strength that the 20th Division could muster for the attack was a little over 2000 men. Most of these troops had been without food for some time. They were suffering from starvation, malaria, and skin diseases, and morale was cracking. They were short of both ammunition and weapons. The 41st Division and its attached units, totaling nearly 1750 men by the morning of August 1, were in equally bad shape. Nevertheless, General Adachi was determined to make one last attack with the nearly 4000 troops now available to him in the Afua area.
Despite sensing minimal Japanese resistance to the north, Hall was eager to mount a robust counteroffensive against the 18th Army. The 2d Battalion, 124th Infantry, which had been patrolling in the Palauru-Chinapelli area, was relieved from that duty by the 1st Battalion, 169th Infantry, and on the 30th joined its regiment at the Driniumor. The 2d Battalion, 169th Infantry, was already at the river. Tactical control of the counteroffensive was vested in Col. Edward M. Starr, commanding officer of the 124th Infantry, whose counterattack organization was to be known as TED Force. The 1st Battalion, 124th Infantry, was commanded by Maj. Ralph D. Burns; the 2d Battalion by Lt. Col. Robert M. Fowler; the 3d Battalion by Lt. Col. George D. Williams; and the 2d Battalion, 169th Infantry, by Maj. William F. Lewis. To avoid confusion, the four battalions were referred to by the last names of their commanders rather than by their number designations. Fowler's battalion, attacking along the coast, was to be supplied by ration trains moving along the coastal trail from Anamo. The rest of TED Force, pushing through trackless, dense jungle, was to be supplied by airdrop. The 149th Field Artillery Battalion, augmented by the Cannon Company, 124th Infantry, was responsible for artillery support, but when necessary the 129th Field Artillery was to add its fire to that of the 149th. All the artillery units were emplaced on the beach west of the Driniumor's mouth. The positions which the 124th Infantry and the 2d Battalion, 169th Infantry, left vacant on the Driniumor were to be occupied by the 2d and 3d Battalions, 128th Infantry. Colonel Starr had succeeded General Stark as commander of North Force on 18 July when the arrival of elements of the 43d Division at Aitape made it necessary for General Stark, the assistant division commander, to move back to BLUE Beach for administrative duties. General Stark apparently also reassumed command of the Western Sector, in place of General Hutchinson, Assistant Division Commander, 31st Division, who had rejoined his division when it, less the 124th Infantry, moved to a new operational area in western New Guinea. When TED Force was organized, North Force as such apparently ceased to exist, and the 128th Infantry took over the defensive functions previously assigned to North Force on the Driniumor. The name TED Force originated from the diminutive for Colonel Starr's first name. There were always so many units from different divisions and regiments operating along the Driniumor that the task force usually found it more convenient to use names rather than numbers for unit designations. The names, usually derived from the commanding officers, served not only to lessen confusion but also did double duty as code names.
The attack was to be carried out with three battalions abreast along a front of 3,000 yards, and the fourth in reserve and in position to protect the right flank of the advancing force. The four battalions were to move east to the line of Niumen Creek, destroying all enemy found between that stream and the Driniumor within the 3,000-yard-wide zone of responsibility. Upon their arrival on the Niumen the battalions were to reorganize and prepare for further advances either east or south upon orders from General Hall. All three battalions of the 124th Infantry began crossing the Driniumor on schedule at 0800, 31 July, moving into terrain concerning which only incomplete and sometimes inaccurate information was available. The 1st Battalion faced delays from enemy delaying actions but eventually reached the creek by August 1, while the remaining battalions advanced inland, also reaching Niumen successfully.
The 1st Battalion’s advance company had been held up about 800 yards east of the Driniumor by elements of the 1st Battalion, 239th Infantry, which had been left along the river when the rest of that Japanese regiment had moved south to Afua on 26 July. Burns' men continued to encounter strong opposition from 239th Infantry elements throughout the day and did not break off contact until 1730, when the battalion bivouacked for the night still 800 yards west of Niumen Creek. Company A had become separated during the day and remained some 550 yards northwest of the main body for the night. Both sections of the battalion were out of touch with the rest of TED Force. The 3d Battalion, 124th Infantry (Williams), crossed the Driniumor at a point about 3,000 yards inland and reached the Niumen about 1400, having encountered only scattered rifle fire. Lewis' 2d Battalion, 169th Infantry, which followed Williams' command, made no contact with the enemy and bivouacked for the night about 500 yards west of Williams. All battalions spent the next day, 1 August, consolidating and patrolling along Neumen Creek, and Burns' unit moved up into line with the others.
Meanwhile, Cunningham planned his own offensive aimed at dismantling the Triangle position following a reconnaissance mission along the Afua-Palauru trail. However, preliminary actions were disrupted when two companies launched a surprise attack from the southwest against Troop C's lines at 06:20 on August 1. General Cunningham immediately canceled the planned reconnaissance in force into the triangle area and turned his attention to this new threat. The first Japanese assault units were quickly reinforced, and the enemy moved forward against Troop C in massed waves along a narrow front. A bloody battle ensued as the enemy, apparently determined to commit suicide, continued his mass attacks. South Force called for artillery support, which was quickly forthcoming and which greatly helped Troop C to throw back the enemy assaults. By 0800 the Japanese had withdrawn and the battle area had become strangely quiet. Patrols were sent out from the cavalry perimeter to reconnoiter. These parties counted 180 dead Japanese in front of Troop C's lines, and it was considered probable that the enemy had carried off many more dead and wounded. Troop C, on the other hand, had lost but 5 men killed and 6 wounded. Examination of the enemy dead disclosed that elements of both the 80th and 238th Infantry Regiments had participated in the attacks. Thirty minutes later, Cunningham proceeded with his reconnaissance mission, encountering minimal resistance before returning in the afternoon. Despite capturing documents indicating an impending major assault, Cunningham deployed the 2nd Squadron as a mobile reserve at his command post.
Although the movement of the 2d Squadron had apparently been well advised, the Japanese did not attack the command post area. Instead, at 1900, elements of the 41st Division struck the 1st Battalion, 127th Infantry, at its lines south of the dropping ground. This attack was preceded by fire from a 70-mm. or 75-mm. artillery piece which the Japanese had managed to sneak into the area within 150 yards of Company B, 127th Infantry. Following a few rounds from this weapon, Japanese infantry charged forward in four separate waves, employing perhaps 300 men on a very narrow front. Few of the enemy got near Company B's positions, for the attack was thrown back with artillery, mortar, and machine gun fire, which caused heavy losses among the enemy forces. By 2030, action in the dropping ground area stopped for the night. During the early hours of the next morning, 3 August, the 1st Battalion, 127th Infantry, again heard enemy activity to its front, and about 0730 a small Japanese party struck between Companies A and C. This attack was quickly repulsed, principally by mortar fire from 1st Battalion units. By noon all activity in the 1st Battalion area had ceased, and the Japanese had withdrawn to the southwest.
Concurrently, Cunningham’s 1st Squadron faced attacks from Nakai’s 20th Division, but their suicidal charges were also turned back by resilient defenders. The 1st Squadron, 112th Cavalry, on the left rear of the 1st Battalion, was attacked by another group of Japanese at 1945. This action was probably meant to have been coordinated with the attack on Company B, but, if this were the enemy's intention, something had gone wrong. Apparently there had also been some mix-up in unit dispositions, for both enemy efforts had entailed the use of elements of the 78th, 80th, and 238th Infantry Regiments. After the day's action was finished, the combined effective strength of the first two units was probably not more than 250 men, and the 2d Battalion, 238th Infantry, was practically wiped out. The desperate attacks during the day had been carried out with a complete disregard for self-preservation, and had probably cost the Japanese 300 men killed and at least twice that number wounded.
TED Force was subsequently directed to advance south along Niumen Creek toward the Torricelli Mountains foothills to disrupt Adachi’s supply lines and flank the 18th Army. Supply challenges and dense jungle terrain initially delayed Starr’s southern movement, with his northern battalions only linking up with the southern ones by day's end. The next morning, Starr launched a southward offensive, immediately encountering fierce resistance from the 1st Battalion, 239th Regiment, which held a stubborn defense throughout the day. In response, Starr ordered his 1st Battalion to bypass the engagement and move southwest, advancing unopposed for up to 1000 yards. August 3rd proved relatively calm for Cunningham, as the 1st Battalion, 169th Regiment arrived to bolster the South Force perimeter. However, vigilance remained high in anticipation of Mano’s impending final assault.
On 1 August General Adachi learned that American forces were active in the Yakamul area. It was erroneously reported to him that this was an amphibious operation, a maneuver which the 18th Army commander had feared for some time (actually, the report referred to patrolling by the 2d Battalion, 124th Infantry, along the coast from the mouth of Niumen Creek). He therefore ordered the remaining elements of the 237th Infantry to extricate themselves from the operations in the Afua area and hurry back to Yakamul to reinforce service units in that vicinity. Events moved so rapidly that the remnants of the 237th Infantry never got to Yakamul. Instead, the advance of TED Force made it necessary for General Adachi to change his plans and accelerate a general withdrawal. Communications within forward units of the 18th Army had so broken down that it was not until 3 August that General Adachi learned of the TED Force movement across the Driniumor, although the 1st Battalion, 239th Infantry, had been in contact with TED Force since 31 July. When General Adachi did hear of the American movement, he grossly underestimated the strength of TED Force. Thinking that the American operation was being carried out by only 400 troops, General Adachi merely changed the orders of the 237th Infantry and instructed that regiment to hold the 18th Army's crossing point on the upper Niumen Creek. On the same day, 3 August, General Adachi issued detailed plans for the withdrawal of all 18th Army units to the east side of the Driniumor, a withdrawal which was to begin on 4 or 5 August. The 66th Infantry, 51st Division, was to protect the 20th and 41st Division units as they crossed the Driniumor. The continued advance of TED Force on 3 August prompted General Adachi to change his plans and early on the 4th he ordered the 20th Division to start retreating at noon that day and the 41st Division to break contact on the 5th.
The following morning, elements of the 238th and 239th Regiments emerged from the jungle southwest of the 1st Squadron in a final, desperate charge. Violent action continued in front of the 1st Squadron for about two hours, during which time nearly 200 Japanese were killed at the very edge of the squadron perimeter, principally by machine gun and rifle fire. How many more of the enemy were killed by artillery and mortar fire during the period cannot be estimated, but the banzai tactics undoubtedly cost the Japanese more than the 200 dead counted in front of the 1st Squadron which, in the same two hours, lost only 3 men killed and 4 wounded. By 0900 the last enemy attacks had ceased and the remaining Japanese had withdrawn generally to the south.
Following the enemy withdrawal, Troop E pursued the retreating Japanese southward, encountering sporadic rifle fire as they eliminated remaining stragglers. The terrain encountered on August 4 and subsequent days during the operations of the TED Force east of the Driniumor proved next to impassable. Dense jungle undergrowth covered the ground; the area was thick with heavy rain forest; low but knifelike ridges, separated from each other by deep gullies, were encountered; and swampy spots were plentiful. To add to the difficulties, rain fell during the day--a downpour which turned much of the ground into a quagmire and flooded many dry stream beds. A few new, rough trails, recently cut by the Japanese, were found, but mud made them nearly useless as routes of advance. Low clouds coming in from the Torricelli Mountains to the south prevented ration and ammunition drops and increased communication difficulties. Battalions ran low on drinking water, for weather conditions prevented resupply of water purification tablets and the assault companies had neither time nor equipment to clean water by other means. Radio communication between battalions, from battalions to TED Force headquarters, and from the latter to higher echelons was nearly nonexistent, for the heavy jungle and the damp weather cut down the efficiency of all radio equipment.
It had been hoped that the advance on the 4th would carry TED Force south to the main Japanese supply route, but the trail reached by Burns', Lewis', and Williams' battalions was another route which had not been used by military traffic for some time. Possibly, it was a section of the native trail to Afua and, as such, purposely avoided by the Japanese inasmuch as parts of it could be seen from the air. In any case, the track cut on the 4th lay about 1,200 yards north of the east-west trail which most of the Japanese forces moving to and from the Afua area had been using. Colonel Starr, realizing that the main Japanese supply route had not yet been severed, ordered his units to continue southward on the 5th, on which day the advance was resumed about 0800 hours with Williams leading and Lewis' battalion about 400 yards to the rear. Pushing south along now precipitous and mountainous banks of the upper Niumen, Williams' unit was opposed by only scattered rifle fire until 1100, when it was decisively halted by a strong Japanese force conducting a stubborn defense. On August 5, learning that TED Force was approaching the point at which the 18th Army's main line of communications crossed the upper reaches of Niumen Creek, General Adachi had also ordered the 8th Independent Engineers to aid the remnants of the 237th Infantry in holding the crossing point. It was this combined 237th Infantry-8th Engineers force that Williams' 3d Battalion, 124th Infantry, had encountered about 1100 on 5 August. The composite Japanese unit was dug in along a 1,000-foot high ridge across Williams' line of advance and threatened to outflank the battalion by occupying other high ground nearby. Despite artillery and mortar support, Williams' men were unable to advance. Colonel Starr ordered Lewis' unit to bypass the fight and continue south to locate and cut the Japanese main supply route. Fighting at Williams' front continued through most of the afternoon, and Colonel Starr realized that the Japanese force could not be dislodged that day. Fowlers' battalion was brought up to the rear of Williams' and late in the afternoon set up a new perimeter with the regimental command post. Before dark, Williams' men withdrew slightly from their most forward positions so that artillery concentrations could be placed along the front. Lewis' unit, which had moved off to the southeast to bypass Williams' fight, made little progress in very rough terrain and was cut off from the rest of TED Force before it could swing westward.
Meanwhile, another battalion to the west encountered minimal resistance as it intercepted the main enemy trail east of the Driniumor, linking up with patrols from Cunningham’s 2nd Squadron. Action on the 6th started earlier than TED Force expected. About 0300 approximately 400 Japanese attacked Williams' perimeter. This enemy force comprised elements of the 41st Division, supported by men of the 26th Field Artillery of the 20th Division and some remnants of the 8th Independent Engineers. Attacking under cover of fire from machine guns, mortars, and 75-mm. mountain guns, the Japanese force was attempting to secure fords over the upper reaches of Niumen Creek and protect the withdrawal of other elements of 18th Army units from Afua. Though surprised, Williams' men held back the initial onslaught. Reportedly, Japanese riflemen then climbed trees surrounding Williams' perimeter to pin down the American troops while other Japanese continued to attack on the ground.
Fowler's unit, under orders to bypass Williams' fight and move around the enemy left, started moving about 0800 hours but soon found the terrain made it impossible to avoid contact with the Japanese opposing Williams. The Japanese, having control of most commanding ground in the area, stopped Fowler's leading company. Action was not rapid. The terrain made all movements slow and laborious, and much time had to be taken to co-ordinate artillery support fire properly. Under cover of artillery fire, another company of Fowler's battalion, creeping slowly through ravines and up an almost vertical cliff, worked around to unoccupied high ground on the Japanese left. The rest of the battalion was successfully disengaged to secure more commanding terrain in the same area. The Japanese, finding themselves outflanked and subjected to increasingly heavy artillery and mortar fire, began to withdraw southward in midafternoon, relieving the pressure on Williams' front. Fowler's battalion, in enveloping the Japanese left, had moved north and then westward and the maneuver had carried the unit by dark to a point just north of the main trail about 750 yards east of Burns' battalion. Williams' men withdrew to reorganize, after disengaging from the enemy forces late in the afternoon; at dark, having resumed the march westward, they secured high ground north of the trail. The ground covered during the day by Williams' battalion was little more than 500 yards west of the position it had occupied the previous night. The unit probably could have moved farther, but Colonel Starr halted it so as not to increase the distance from Lewis' battalion which was, in effect, lost. The unit had laboriously struggled over extremely rough and trackless ground during the day, fighting in the afternoon against a number of Japanese who had withdrawn from Williams' front. For the night, Lewis' men set up a perimeter about 800 yards south-southeast of the scene of Williams' fighting. With Adachi’s escape route blocked, Starr’s battalions advanced southwestward, achieving notable success by killing around 500 Japanese soldiers between August 6 and 7.
In the interim, Cunningham’s South Force completed operations in their sector, achieving a successful attack led by Howe that ousted the remaining disorganized Japanese presence from Afua on August 6. Two days later, the 124th Regiment advanced to the Driniumor, claiming to have eliminated approximately 1800 Japanese soldiers since the start of their counteroffensive, at the cost of 50 men killed and 80 wounded. With the rest of Adachi’s 18th Army retreating towards Wewak, General Gill declared Afua secure by the evening of August 9. Following the conclusion of the Battle of the Driniumor River, the fatigued units of the 32nd Division, including the 124th Regiment and 112th Cavalry Regiment, were relieved by units from Wing’s 43rd Division. From August 16 to 25, Wing’s regiments conducted final combat missions in the Aitape region, encountering minimal Japanese resistance east of the Driniumor, except for delaying actions near the mouth of the Dandriwad River by patrols of the 103rd Regiment. Consequently, General Krueger declared the Aitape operation concluded on August 25, confident that the 18th Army posed no further threat to the Tadji airstrips. Adachi’s forces had indeed suffered a decisive and costly defeat, rendering them incapable of posing a significant threat to Allied forces anywhere in New Guinea. The campaign to secure the Aitape area and defeat the 18th Army resulted in approximately 440 Allied soldiers killed, 2550 wounded, and 10 missing, while inflicting losses of around 8821 Japanese killed and 98 captured, including 2669 killed and 34 taken prisoner from August 2 to 9 alone. Adachi himself reported losing 9000 men and virtually annihilating seven regiments.

- 143 - Pacific War Podcast - Fall of Myitkyina 12 - August 19, 1944
13 8月· The Pacific War - week by week
Last time we spoke about the fall of Guam and actions in New Guinea. General Shepherd's Marines had secured the Orote Peninsula, while General Turnage's Marines pushed the Japanese northwards. General Bruce's 77th Division prepared for an eastward assault, and engineers attempted, but failed, to build a supply road to Yona. Geiger's offensive began on July 31, with Marines quickly capturing Agaña and advancing despite dense jungle and resistance. The 77th Division faced tough terrain but liberated 2,000 Guamanians. The push north continued, facing logistical challenges and mined roads. By August 7th, coordinated attacks cleared key areas, culminating in the defeat of remaining Japanese forces by August 11. Guam was back in American hands although scattered Japanese forces continued guerrilla warfare until the war's conclusion. Thus the Marianas campaign had finally come to a conclusion, and now the allies were adding more bass of operation to hit the Japanese home islands.
This episode is the Fall of Myitkyina

This week we are diving back over to the northern Burma front. Despite holding Myitkyina through a rainy, muddy summer-long siege, by late July, the Japanese had been gradually cornered into a small perimeter, cut off from all supply lines and running short on ammunition. The situation worsened due to a leadership crisis, between the two Japanese leaders was a matter of semantics. Colonel Maruyama of the 114th Regiment who was in charge of the defense of the city, interpreted his orders to “facilitate the future operations of 33rd Army ‘by securing the vital areas in the vicinity of Myitkyina’,” as a call to defend the city street-by-street, house-by-house. When General Minakami of the 56th Division arrived, he pointed out that all Maruyama had to do to satisfy his orders was simply to continue to deny the Allies access to the Ledo-Kamaing road. Minakami thus found himself in a rather difficult position in regard to the command of the Myitkyina Garrison. Maruyama had conducted an excellent defense, was fully familiar with the situation and, because of his position as former commander, exercised considerable authority. Shortly after Minakami’s assumption of command, General Honda asked how long Myitkyina could stand. Minakami replied that the garrison might be able to hold out for as long as two months. A few days later, Honda was surprised to receive a second message stating, "The Myitkyina Garrison finds it difficult to hold with the poor defense facilities and meager supplies of ammunition." The Army staff concluded that the first message was undoubtedly Minakami's personal opinion as it reflected his determined character and that the second message incorporated the views of Maruyama who was more cognizant of the actual situation. In order that there should be no doubt as to the importance of holding Myitkyina, Honda sent the following message, "Maj. Gen. Minakami will defend Myitkyina to the death” — a message sent with deep regret and sadness according to the staff officers who wrote and dispatched the order.
Heavy casualties had reduced the Japanese forces from around 3,000 to fewer than 1,500, further weakening the garrison's defensive capabilities. This number included the heavily wounded and hospital patients, who could only be evacuated by drifting down the Irrawaddy River on rafts, often intercepted by the unforgiving Kachin Levies. On July 24, eight rafts and a boat laden with Japanese were attacked on the Irrawaddy by Kachins of the OSS Detachment 101. Twenty-four Japanese were killed, two captured, and then it was learned these were hospital patients fleeing Myitkyina. Three more Japanese seized by friendly Burmans revealed that hospital patients were being evacuated by the simple expedient of letting them drift down the river on rafts.
As these fierce defenders began to falter, General Wessels felt ready to launch his final push. Reinforced by the 149th and 90th Regiments, the American-Chinese forces made daily gains of several hundred yards during the last days of July, though at a significant cost. As the Japanese-held area shrank, counterattacks became less dynamic, captured positions were less fortified, and many Japanese dead were found to be severely wounded men returned to the line. Unbeknownst to the Americans, the desperate defenders had requested a withdrawal to the east by the end of the month. Though Minakami had intended to fight to the last, he ultimately agreed to preserve his men’s lives. On the night of August 1, the Japanese began their escape, crossing the Irrawaddy east of the town.
Weighing the many evidences that control of the situation was rapidly passing into their hands, Wessels and his colleagues drafted a new plan of attack. It included an ingenious device, credited to General Pan Yu-kun of the 50th Division. A raiding party, formed into fifteen heavily armed sections, was organized and briefed on infiltrating Japanese lines facing the 50th Division. Having made its way through the Japanese lines in darkness, it was to remain hidden until 0430 when the 50th would assault while the raiders spread confusion behind the Japanese lines. Meanwhile, air reconnaissance revealed many rafts moored against the Irrawaddy within the Japanese lines. "At 0300 hours (3 August), when the moon went down and rain and thunder set in, the raiding party of the 50th Division moved out. The approach was detected only once and some shots were fired at the raiders, who hit the ground. The Chinese did not return fire however, and after laying low for a while, moved out again quietly and cautiously."
While the raiders created confusion behind Japanese lines, the 50th Division launched a full attack, quickly overwhelming the remaining enemy positions and capturing 187 prisoners, thus securing Myitkyina for the Chinese. However, about 800 Japanese managed to escape eastward and later rejoined their allies. Minakami was not among them. As the 3rd of August meandered on in a haze of gunfire, blood and rain, Minakami went to sit with his back against a tree. There came the sound of a pistol shot. Japanese officers nearby sprinted to the scene. The general’s orderly was in tears. They found Minakami’s body erect against the tree trunk, facing northeast, towards Japan. The ten-week siege resulted in approximately 3,000 Japanese killed or captured; 972 Chinese killed, 3,184 wounded, and 188 evacuated due to illness; and 272 Americans killed, 955 wounded, and 980 evacuated sick. Overall, the total American-Chinese casualties in 1944 amounted to 13,618 Chinese and 1,327 American casualties. A week later, the Galahad Unit, reduced to only 130 combat-effective men from the original 2,997, was disbanded.
The fall of Myitkyina was General Stilwell’s greatest victory, earning him a promotion to full general on August 1, two days before the city fell. The attack was costly in terms of suffering and losses, but the Mogaung-Myitkyina area was a significant prize. It allowed Ledo Road builders and American transport planes to move to Myitkyina and enabled ground forces to link up with other Chinese forces in neighboring Yunnan. As the fighting moved further south down the Hukawng and Mogaung valleys, it became safer for transports to use the lower, more southerly routes to China. This, in turn, increased Hump deliveries to China from 13,686 tons in May to 18,235 tons in June and 25,454 tons in July.
While the Allies celebrated victories in northern Burma, the situation in China was dire as the Ichi-Go offensive resulted in many Chinese casualties. By August 1, General Yokoyama had amassed 110,000 troops around Hengyang, equipped with five heavy artillery pieces, fifty mountain artillery pieces, and 40,000 shells. Conversely, General Fang’s resilient defenders had dwindled to 3,000 exhausted troops, with their defenses largely destroyed. General Xue Yue’s reinforcements had failed to reach Hengyang, leaving the Chinese forces to rely on the 46th Army to launch an attack along the railway.
On August 4, Yokoyama initiated his main offensive. The 68th and 116th Divisions launched a significant assault from the south and southwest, while the 58th Division quietly positioned itself near the enemy’s northern defenses. Initially, progress was slow. However, by August 5, Yokoyama’s forces had captured Yoping and School Hill. The next day, the 116th Division secured part of the city's defenses. On August 6, the 58th Division breached the city walls from the north, forcing Fang to redeploy troops to counter this new threat. Intense street fighting broke out on August 7 as the defenders valiantly tried to repel the Japanese attacks. By nightfall, the 68th Division had overrun the southern defenses and entered part of the Walled City. Gradually, enemy troops began to surrender, and before dawn on August 8, after 48 days of fierce resistance, Fang was compelled to surrender.
Following the capture of Hengyang, Yokoyama declared the successful completion of the initial phase of Operation Togo and promptly began preparations for the subsequent offensive. In this phase, the Japanese reported casualties of over 3860 killed, 8327 wounded, and 7099 sick, with an estimated Chinese casualty count exceeding 100,000, including 8400 killed and 5000 captured in Hengyang alone. To spearhead the next stage of Operation Togo targeting Guilin and Liuzhou, General Okamura Yasuji's 6th Area Army was established on August 25, comprising the 11th, 23rd, and 34th Armies, along with the 27th, 40th, 64th, and 68th Divisions, alongside additional support units. This allowed General Hata to focus on countering potential American landings on the Chinese coast while Okamura directed the offensives in eastern China. Ahead of this operation, Lieutenant-General Tanaka Hisakazu of the 23rd Army initiated a preliminary offensive in late June, positioning the 23rd Independent Mixed Brigade in the northeastern sector of the Luichow Peninsula, advancing the 22nd Independent Mixed Brigade to the Tanjiang River, securing the Jiangmen area with the 22nd Division, and capturing the Qingyuan sector with the 104th Division. By late August, Yokoyama had deployed six divisions along the Shuangfeng-Leiyang line, poised to eliminate the enemy in the district west of Hengyang. On August 29, he launched the offensive, with over 100,000 troops advancing southwest amidst heavy artillery bombardment. Intense ground and aerial combat ensued, resulting in the loss of 10 Japanese planes and 15 enemy aircraft. Despite fierce resistance from Chinese defenders over three days, their entire line collapsed on September 1, prompting a retreat towards Shaoyang, Qiyang, and Jiahe.
However, the Japanese advanced relentlessly, covering nearly 100 kilometers in the following days without pause. By September 5, both Qiyang and Huochangpingzhen had fallen, followed by the seizure of Lingling Airdrome on September 8 by the 3rd Division. Progressing along a north-south axis, Japanese forces secured Shaoyang and Changning, while the 58th Division captured Dongan on the same day. With initial objectives achieved, Yokoyama ordered further pursuit, with the 3rd and 54th Divisions converging in the Quanzhou area by September 14. Meanwhile, Tanaka prepared for his offensive, with the bulk of the 104th Division moving towards Taipingzhen, and a raiding unit conducting a wide envelopment maneuver along the Zhukeng-Huaiji road towards Wuzhou by September 6. Subsequently, the 23rd Brigade began its northward march from Suixi. However, Tanaka's offensive wouldn't commence for a couple of weeks.
Turning to the broader context of the Pacific War, General Stilwell celebrated a major victory with the fall of Myitkyina, while General Slim's successful defense against Operation U-Go further bolstered Allied morale in the CBI Theater. In Thailand, Prime Minister Phibun's regime faced a significant crisis as Japan struggled to meet the country's essential import needs, leading to inflation, rationing, shortages, black markets, smuggling, corruption, and profiteering. The anti-Japanese Free Thai underground movement, spearheaded by Regent Pridi Banomyong, infiltrated the government, stoking public discontent against both the Japanese occupiers and Phibun's administration.
As a result, following the downfall of the Tojo government, Phibun found himself compelled to step down in late July. For his part, Phibun also was thinking of ways, he claims, to prepare to turn against the Japanese. Part of these preparations included proposals to move the capital to remote Phetchabun, north of Bangkok, and construct a “Buddhist City,” a sort of center for world Buddhism, near Saraburi—both grandiose projects in typically extravagant Phibun style. Moving to the isolated, mountain-ringed Phetchabun, Phibun later argued, would facilitate a Thai uprising against the Japanese. Yet on July 18, the Tojo government in Japan resigned, and only six days later the Thai National Assembly turned down both government bills and forced the resignation of Phibun as prime minister. The deputies in the assembly voted against these plans motivated in part by the fall of Tojo, who was closely associated in their minds with Phibun, in part by their feeling that the war was turning against Japan, and in part by their feeling that Phibun was too closely identified with an authoritarian past that must now be buried for the sake of improving relations with the Allies.
Politician Khuang Aphaiwong then assumed his position as Prime Minister on August 1. Serving as a compromise candidate, he navigated between Phibun's supporters and the opposition while maintaining cooperation with the Japanese and safeguarding Free Thai members who had collaborated with the Allies. Meanwhile, in China, the success of Operation Ichi-Go led to another leadership crisis. Despite the initial rejection of Stilwell commanding troops in China in 1942, the effective Japanese offensive posed a threat of defeat to the Chinese Government, reigniting the debate over command authority. This was especially significant as Chinese troops under Stilwell’s command were achieving significant victories in northern Burma. However, Stilwell's vocal criticism of Chiang Kai-Shek’s corrupt regime and incompetent generals strained their relationship. Chiang favored General Chennault, who proposed that with a monthly allocation of 10,000 tons for operations in northern China, his 14th Air Force could halt the Japanese offensive. Despite his strained relationship with Chennault, Stilwell redirected Hump allocations to increase the 14th Air Force's allocation to 8,425 tons, although he couldn't secure an additional 1,500 tons from the Matterhorn allocation. Chennault's aircraft managed to disrupt the Japanese advance, but failed to halt it completely. In late June, Stilwell faced criticism when Vice-President Henry Wallace visited Chongqing. While Wallace persuaded Chiang to allow a small American observer mission into Communist territory, he also recommended Stilwell's recall due to his perceived lack of diplomacy and strained relations with the Chinese leadership.
Nonetheless, Stilwell maintained the backing of the Joint Chiefs of Staff, and President Roosevelt eventually nominated him to lead the China Theater, on the condition that he make every effort to avoid upsetting the Generalissimo. In July, the President attempted to persuade Chiang to accept this arrangement, but the Generalissimo employed various diplomatic maneuvers to reject the proposal, agreeing "in principle" only after an unspecified period for his forces to adjust. He also requested the presence of a presidential representative to facilitate smooth relations between himself and Stilwell. Major-General Patrick Hurley was appointed to this role and arrived in China in August. Concurrently, the Dixie Mission arrived in Yan'an, where over the following months, American observers assessed Communist society, military tactics, and guerrilla operations, issuing reports that commended them and suggested increased collaboration.
Following the fall of Hengyang, tensions escalated in China, with rumors swirling about potential coup plans involving Marshall Li Zhongren and General Xue Yue against the Generalissimo. Meanwhile, Chennault urged Stilwell to divert Hump airlift capacity to supply ground forces in eastern China, a move opposed by Chiang, who feared supporting potential insurgents with lend-lease equipment. Stilwell, anticipating his imminent assumption of leadership in the China Theater, refrained from challenging Chiang's stance. With significant developments looming, the intensifying rift between Stilwell and Chiang foreshadowed the downfall of one of them.
Elsewhere in the South Pacific, General MacArthur’s troops had finished their final offensive in New Guinea and were preparing to return to the Philippines by way of an intermediate stop at Halmahera Island. To the east, Rabaul was completely surrounded, enduring heavy bombardment from Allied air forces. Meanwhile, on Bougainville, the remaining forces of the 17th Army had retreated to the island's southern region, unable to launch further counterattacks. The living conditions of the Japanese soldiers, never good under the best of circumstances, became increasingly desperate. Added to the dangers that forward troops always faced, such as contact with large American combat patrols, was the growing specter of starvation. Sealed off from regular supplies from New Ireland or New Britain, General Hyakutake's army had to depend entirely on its own laborers to acquire food. The normal rice ration of 750 grams of rice for each soldier was cut in April 1944 to 250 grams, and beginning in September there was no rice ration. A large portion of the available army and naval personnel had to be put to work growing food. Allied pilots took delight in dropping napalm on these garden plots whenever possible. The native workers who had been impressed into service were the first to defect, but soon many soldiers also just walked away from their units, taking the chance of surviving in the jungle on what could be gathered. After the failure of the March attack, morale in most units became deplorably low. There were instances, normally unimagined in the Japanese army, of open insubordination and even mutiny. Although General Hyakutake dreamed of a midsummer offensive, it became obvious that no operations as large as that smashed in March could be undertaken for months, if ever. Thus, almost as if by agreement, both sides adopted a defensive posture that minimized the conflict in the no-man's-land between them.
In the Central Pacific, significant progress had been made over the past year, marked by the complete capture of the Gilbert, Marshall, and Mariana Islands, strengthening the Allied presence and providing a launching point for future offensives into the heart of the Japanese Empire. The next target for Admiral Nimitz was the Palaus, to be invaded concurrently with Halmahera. However, the architect of this southwestern advance was not Admiral Spruance, who had been overseeing operations with the 5th Fleet. Instead, it was Admiral Halsey’s 3rd Fleet, known as the "Department of Dirty Tricks," that had been strategizing the next moves from Hawaii. Now, Admiral Halsey was set to assume command of the Pacific Fleet, leading the charge to the Palaus and the Philippines. This rotation in leadership between Halsey’s 3rd Fleet and Spruance’s 5th Fleet was orchestrated by Nimitz to maintain operational tempo and confuse the Japanese. The alternating command structure allowed for continuous planning of future operations while the active fleet conducted current ones.
However, Tokyo was apprehensive about a potential invasion of the Philippines and sought to bolster its defenses. Following the surrender of the US Army Forces in the Philippines, the 14th Army, led by Lieutenant-General Tanaka Shizuichi, worked to establish military administration, secure cooperation from civilian institutions, and quell guerrilla groups across the countryside. Despite their endeavors, their control over certain regions, particularly in the Visayas and Mindanao, remained fragile. Allied submarines and aircraft from Australia and New Guinea also delivered supplies like signal equipment, weapons, explosives, propaganda materials, and counterfeit currency to support the guerrilla forces, further impeding Japanese efforts. Additionally, with the deteriorating situation in the South and Central Pacific, more troops were redirected from the Philippines’ garrison to other areas, weakening the 14th Army, now commanded by Lieutenant-General Kuroda Shigenori since May 19, 1943. Undermanned and stretched thin, the Japanese halted their suppression operations in August, hoping that the imminent declaration of independence by the Second Philippine Republic would lead guerrillas to surrender. However, this strategy backfired, as the guerrillas only grew stronger during the pause. Consequently, Kuroda restarted intensive suppression operations in 1944, but guerrilla activities escalated in anticipation of the imminent liberation by American forces. As a result, the guerrillas gained strength in the following months, providing valuable intelligence to MacArthur’s forces in preparation for their eventual return. Given this context, it was evident that the 14th Army would be ill-equipped to withstand an American invasion under the current circumstances.
Due to its crucial strategic location bridging Japan and the southern region rich in natural resources, Japan couldn't risk losing the Philippines. It served as their primary rear base supporting the main defense perimeter. The Philippines were also to play the role of a rear base of operations–an assembly and staging area for troops and supplies and a concentration area for air reserves, to support operations at any threatened point on the main defense perimeter from the Marianas south to Western New Guinea and the Banda Sea area. To implement these plans, IGHQ in October 1943 directed the 14th Army to complete the establishment of the necessary base facilities by the spring of 1944. Major emphasis in this program was laid upon the construction of air bases. The Army alone planned to build or improve 30 fields in addition to 13 already in operational use or partially completed. The Navy projected 21 fields and seaplane bases to be ready for operational use by the end of 1944, expanding its total number of Philippine bases to 33. Line of communications and other rear area base installations were also to be expanded and improved. Of the 30 Army airfields projected in October 1943, six had been generally completed by May 1944, and 24 under construction. Of the 21 projected Navy fields, 15 were still incomplete by then.
Consequently, in early 1944, the decision was made to strengthen the garrison in the Philippines. Initially, this involved reorganizing and expanding existing garrison units to establish four new independent mixed brigades. These brigades were primarily tasked with suppressing guerrilla activity, while infantry divisions were assigned to defend against potential enemy landings. However, despite the estimation that at least seven divisions were necessary for the defense of Luzon, the Visayas, and Mindanao, only the 16th Division was available. Additionally, it was deemed crucial to bolster air strength with at least two air divisions, anticipating Allied invasions in Halmahera and Palau before advancing to the Philippines. Plans were formulated in March to deploy reinforcements within eight months. In mid-May, General Terauchi relocated his headquarters to Manila to oversee operations more closely. Concurrently, efforts were made to transport the 30th Division to Mindanao and bring the 4th Air Army to Manila. Furthermore, the Philippines were reinforced with the 2nd and 4th Air Divisions, the latter being tasked with constructing 30 new airfields.
In June, approximately 20,000 inexperienced replacements were transported to the Philippines to bolster the recently-formed independent mixed brigades, filling them up to division strength. Subsequently, in July, the 100th, 102nd, 103rd, and 105th Divisions were activated, along with the establishment of the 54th and 55th Independent Mixed Brigades. It's ironic that despite this reinforcement, the main Japanese forces were as inexperienced as the Philippine Army during MacArthur’s defense. Nonetheless, Terauchi was resolute in further fortifying the Philippines to prevent its fall, unlike MacArthur's situation. By mid-July, the reinforced 58th Independent Mixed Brigade arrived at Lingayen. Later that month, the 14th Army underwent reorganization into the 14th Area Army, with units directly under its command tasked with defending the northern Philippines. Meanwhile, the 35th Army, led by Lieutenant-General Suzuki Sosaki, was established under the 14th Area Army to defend Mindanao and the Visayas. Additionally, Tokyo finalized plans for decisive battle operations, codenamed Sho-Go, covering the Philippines-Formosa-Ryukyus-Japan-Kuriles area. This determined the disposition of Army and Navy air forces across the Pacific, with the Philippines receiving the reorganized 1st and 2nd Air Fleets and the 4th Air Army. The Philippine garrison was strengthened to a total of nine divisions and four brigades, with the 1st Division at Shanghai and the 68th Independent Brigade at Formosa designated as general reserves. Defenses and fortifications were constructed at Luzon in preparation for the decisive battle there.
Known as the Combined Fleet Top Secret Operations Order No. 84, issued on 1 August, this fixed the new tactical grouping of naval forces for the Sho-Go Operations. Almost the entire surface combat strength of the Fleet was included in a Task Force placed under the overall command of the First Mobile Fleet Commander, ViceAdm. Ozawa Jisaburo. This force was broken down into three tactical groups: (1) the Task Force Main Body, directly commanded by ViceAdm. Ozawa and consisting of most of the Third Fleet (carrier forces): (2) the First Striking Force, commanded by Vice Adm. Kurita Takeo and made up of the Second Fleet with part of the 10th Destroyer Squadron attached: (3) the Second Striking Force, commanded by Vice Adm. Shima Kiyohide and composed of the Fifth Fleet plus two destroyer divisions and the battleships Fuso and Yamashiro. The First Striking Force would be stationed at Lingga Anchorage, while the Task Force Main Body and the Second Striking Force would be stationed in the western part of the Inland Sea. However, if an enemy attack was expected, the First Striking Force would advance from Lingga Anchorage to Brunei, Coron or Guimaras while the Task Force Main Body and the Second Striking Force remained in the Inland Sea and prepared to attack the north flank of the enemy task force. During August, the Navy Section of Imperial General Headquarters also took action to give the Combined Fleet more unified operational control of naval forces in order to facilitate the execution of the Sho-Go plans. On 9 August the General Escort Command and units assigned to naval stations were placed under operational command of the Combined Fleet, and on 21 August the China Area Fleet was similarly placed under Combined Fleet command. On 10 August the 1st Carrier Division, reorganized around two newly-commissioned regular carriers, was added to the Task Force Main Body. Vice Adm. Ozawa, Task Force Commander, meanwhile set 15 October as the target date for completion of the reorganization and training of the 3d and 4th Carrier Division air groups. Concurrently with these preparations, steps were taken to strengthen the antiaircraft armament of combat units.
Accordingly, the Japanese sought to deploy the 8th and 26th Divisions, the 2nd Tank Division, and the 61st Independent Mixed Brigade to the Luzon region for a decisive battle. However, enemy submarines posed a constant threat. Since February, they had been patrolling the South China Sea, targeting the Hi Convoys supplying Japanese territories in Southeast Asia and Japan itself. During these engagements, Admiral Ijuin was killed aboard the patrol boat Iki. Between August 18 and 25, Admiral Kajioka's Hi-71 convoy, carrying the 26th Division, was attacked by six American submarines. The escort carrier Taiyo, destroyers Yunagi and Asakaze, two oilers, four transports, and three kaibokans were sunk, with 7420 soldiers of the 26th Division lost. The submarine Harder was the only American vessel sunk in retaliation. Kajioka's Hi-72 convoy, returning from Luzon, was also attacked, resulting in the sinking of his flagship, the kaibokan Hirato, and the loss of the destroyer Shikinami, three transports, and one oiler. Despite these setbacks, advance units of the 8th Division, 2nd Tank Division, and 61st Independent Mixed Brigade successfully reached the Philippines in September.

After months the siege of Myitkyina had finally ended. The Japanese had held out as long as they could, but lack of supplies and rather terrible leadership lost them the fight. Meanwhile, in China, Japanese offensives intensified, challenging Chinese defenses and leadership. It seemed war was coming to the Philippines, where the Japanese prepared to fight to the death.

- 142 - Pacific War Podcast - Fall of Guam August 5 - August 12, 1944
6 8月· The Pacific War - week by week
Last time we spoke about fall of Tinian and battle of Sansapor. Following the capture of Noemfoor and Biak, the Allies advanced to the Vogelkop Peninsula, constructing vital airbases. MacArthur initially focused on seizing Sorong and Waigeo Island, but operations accelerated, making Klamono oilfields non-viable, and oil rehabilitation projects in the Dutch East Indies were prioritized by the Joint Chiefs of Staff. MacArthur planned reconnaissance in the Mar-Sansapor area. The 6th Division launched Operation Typhoon, and Task Force 77 executed landings on July 30, 1944. Airfields were built, and patrols eliminated Japanese forces. Meanwhile, Tinian saw intense fighting, with Marines securing key objectives by July 31. Following massive bombardments, Marines continued advancing, encountering heavy resistance but eventually declaring Tinian secure on August 1. Guam operations saw similar advances with coordinated attacks overcoming Japanese defenses.
This episode is the Fall of Guam

This weeks podcast brings us back into the intense action in Guam. As we previously observed in Guam, General Shepherd’s Marine brigade had effectively captured the Orote Peninsula, while General Turnage’s 3rd Marine Division had reached the designated beachhead line, pushing back a weakened Japanese force retreating northward. Meanwhile, General Bruce’s 77th Division maintained control of the southern beachhead line, preparing for a general eastward assault. An engineer battalion began constructing a supply road towards Yona, a project that ultimately failed to support the infantry's advance.
On July 30, Turnage’s Marines and the infantrymen sent patrols to gauge the strength of the Japanese forces, but dense foliage obscured enemy movements. Geiger eventually concluded that defensive positions were likely near the Agaña-Pago Bay Road. He planned an initial advance toward the general line of Agaña-Famja-Pago Bay, followed by a northeastward attack. Turnage’s Marines were assigned to capture the capital, Agaña, and the strategic Tiyan Airfield on the left, while Bruce’s infantry aimed to secure the Pago Bay area on the right.
Following two days of intense artillery and naval bombardment, Geiger’s offensive commenced at 06:30 on July 31. On the left, Turnage’s units encountered minimal resistance. The 3rd Marines, now led by Colonel James Stuart, quickly occupied the ruins of the abandoned Agaña and moved beyond the O-1 Line to secure the main northbound roads. The 21st Marines advanced through dense underbrush, reaching O-1 after neutralizing an enemy pillbox near Famja. When Lieutenant Colonel Duplantis 3rd battalion, 21st marines brought his command post forward, a curious incident occurred which illustrated the confusion of the Japanese. Someone in the battalion command group sighted one of the bypassed enemy groups, estimated to be about 15-20, led by an officer, moving toward the new CP area. The Marines held their fire, and when the small unit got to within 150 yards of the waiting men, an interpreter called to the Nipponese to surrender. Apparently thinking they had finally reached friendly lines, they started forward, then stopped to hold a hurried conference. The chattering was interrupted by the interpreter urging them forward, but by this time the aggregation had decided they were in unfriendly territory. They broke and ran in all directions; the Marines opened fire, killing and wounding about half of the intruders. Those still alive escaped into the protecting foliage. The 9th Marines destroyed a delaying detachment at Ordot and two tanks during their successful push to O-1.
Colonel Hamilton’s 1st and 3rd Battalions, along with Colonel Tanzola’s 3rd Battalion, advanced to the right, moving through steep slopes and narrow gorges in columns. They successfully reached Yona and the Pago River without encountering any opposition. With the Reconnaissance Troop protecting the south flank, General Bruce's 77th Infantry Division started toward the east coast of Guam at 7:00, 31 July. Elements of the 307th, with 3/305 attached, led the way in a column of battalions. Lack of enemy resistance permitted battalions to move with companies in column; even so, the march proved most difficult. The troops initially scaled steep slopes, slid down into narrow gorges, and followed along the foothills southwest of the central mountain range of Guam. For a time, vehicles followed, but soon the terrain became so rough that even jeeps could not traverse it. As one infantryman later wrote: “The distance across the island is not far, as the crow flies, but unluckily we can't fly. The nearest I came to flying was while descending the slippery side of a mountain in a sitting position. . . . After advancing a few yards you find that the [bolt] handle of the machine gun on your shoulder, your pack and shovel, canteens, knife, and machete all stick out at right angles and are as tenacious in their grip on the surrounding underbrush as a dozen grappling hooks. . . . The flies and mosquitos have discovered your route of march and have called up all the reinforcements including the underfed and undernourished who regard us as nothing but walking blood banks. We continue to push on. . . .”
During this movement, Hamilton’s Company L liberated 2,000 Guamanians from a concentration camp near Asinan. Soldiers willingly gave their rations and cigarettes to the undernourished men and women who were almost overcome with joy at once again seeing Americans. Men of the 77th Division soon forgot the long, tiresome cross-island march as the full realization of the expression, "liberation of enslaved peoples," came to the troops. Following the Orote operations, Shepherd’s brigade was ordered to take over the southern half of the beachhead line from Inalas to Magpo Point, relieving the 305th and 306th Regiments. On August 1, Geiger’s northward push continued, with the 305th moving to the Yona area and the 306th heading to Pago Bay. The 305th and 307th Regiments advanced slowly through rough terrain without opposition, reaching the O-2 Line by nightfall. On the left, Turnage began his advance with three regiments abreast, but the 3rd and 9th Marines eventually pinched out the 21st upon reaching the intermediate D-2A Line. At 15:00, these two regiments resumed their advance against slight resistance and reached O-2 by nightfall. The main challenge during this period was moving supplies forward, as both divisions relied on the same coastal road, heavily mined by the Japanese. With the rapid advance came the necessity to move supply distribution points closer to the front. Trucks began to roll over the already crowded coast highway to establish an advanced division dump in the Agaña Central Plaza area. Artillery units started to displace forward so that continuous direct support would be available to the assault units. This added traffic, plus the fact that the 77th Division would have to move supplies over the same road, presented a problem to the engineers. In an effort to alleviate the situation, the 25th Naval Construction Battalion and the 19th Marines put all available men to work improving existing roads and trails. Yet despite these efforts, by August 1, the problem of getting supplies forward was becoming more serious. The main coast road –and only one that ran from west to east on northern Guam– over which all traffic had to move had been heavily mined. The Japanese had placed aerial bombs and single-horned mines at road junctions and intersections in and around Agaña. In addition to being mined and heavily congested, the two-lane, hard-surfaced Agaña-Pago Bay Road was overused, poorly maintained and, with frequent rain, soon deteriorated badly. In the end, the engineers could not properly maintain the road and still allow the essential supply convoys through. On the morning of August 2, artillery and warships bombed the new positions General Obata was trying to establish around Mount Santa Rosa. Meanwhile, the Marines and infantrymen continued their pursuit northwards, aiming to reach the O-3 Line behind Japanese delaying positions at Finegayan and Mount Barrigada.
On the left, the 9th Marines swiftly captured Tiyan Airfield, but their advance was hampered by dense jungle. Despite this, they managed to gain 1800 yards while the 21st Marines cleared the Saupon Point-Ypao Point area of small enemy groups. On the right, the 77th Division's advance was initially covered by a 14-tank patrol conducting reconnaissance in the Barrigada area, where they faced heavy resistance. The 307th Regiment quickly secured Price Road, but Tanzola’s 3rd Battalion was halted by concealed machine-gun positions near Barrigada Well. Subsequently, the 307th, now led by Lieutenant-Colonel Thomas Manuel, was also stopped near the village, with Manuel’s 1st and 3rd Battalions becoming mixed up just as an enemy tank broke through their lines. After numerous failed attempts to dislodge the enemy, Companies G and E managed to penetrate the Japanese lines in the afternoon, although Company G had to be evacuated by nightfall. Meanwhile, the 305th moved up and consolidated its lines with the 307th. Since Bruce’s infantrymen failed to link up with the Marines, Colonel Butler’s 2nd Battalion was sent to fill the gap between the divisions. Following a reorganization, the 305th and 307th Regiments attacked again the next morning, encountering surprisingly little resistance as they moved through Barrigada and secured the vital well. The 77th Division had a special reason for wanting to reach Barrigada quickly. The reservoir and pump, located 100 yards northwest of Road Junction 306, could supply 20000 gallons of water daily to the troops. Until now, the men of the division had quenched their thirst by getting water from streams and creeks. But in the northern part of Guam there were no streams, and the reservoir would be the only source of supply. With tanks leading the way, Manuel’s 3rd Battalion advanced quickly and reached the summit of Mount Barrigada, although the 2nd Battalion lagged behind. Meanwhile, the 305th Regiment engaged in several isolated skirmishes but still managed to link up with the 307th.
To the left, Turnage had also resumed his advance toward O-3. Although the 3rd Marines encountered little resistance and reached their objective successfully, Colonel Craig’s 1st Battalion was halted by heavy fire near Finegayan after destroying a Japanese stronghold. That night, the Marines faced mortar and tank attacks, but these assaults made little progress. Meanwhile, as the 22nd Marines patrolled southern Guam, the 4th Regiment was held in reserve at Toto. On August 4, the remainder of Shepherd’s brigade began moving to Toto, leaving only Colonel Schneider’s 1st Battalion and the 6th Defense Battalion behind. Following Turnage’s orders, the 21st Marines were positioned between the other two regiments to reach O-3 near Dededo. At the same time, Craig’s 1st Battalion made minimal gains toward Finegayan, while the rest of the 9th Marines advanced to O-3 and successfully severed the Finegayan-Barrigada Road. To the right, Bruce’s infantrymen, following an artillery barrage, advanced to O-3, overcoming terrain difficulties and securing the objective line by nightfall. On August 5, Turnage’s three regiments continued their advance, pushing past O-3. The 3rd Marines reached Amantes Point, and Craig’s 1st Battalion finally overran the remaining Japanese positions at Finegayan. Behind them, Shepherd’s brigade moved to Dededo, preparing to take over the left flank for the final push. Meanwhile, as the 306th Regiment relieved the exhausted 307th, Tanzola’s men continued to fight through the dense jungle, with his 2nd Battalion reaching the O-4 Line by nightfall.
During a nighttime raid, the 1st Battalion was targeted, resulting in 48 casualties. Following this, the 2nd Battalion encountered the tanks the next morning, eventually neutralizing them but suffering an additional 46 casualties. Bruce’s regiments gathered at O-4 to prepare for an attack on Mount Santa Rosa, where Obata had concentrated his forces. Turnage’s regiments also resumed their attack, advancing with minimal resistance. Geiger initiated the final push on August 7, with Turnage’s Marines facing minor obstacles due to jungle terrain. Despite this, the 3rd Marine Division reached the O-5 Line by nightfall. Shepherd’s brigade swiftly progressed along the coast, joining forces with the 3rd Marines. Meanwhile, the 306th and 307th Regiments prepared for a coordinated attack. Bruce's strategy involved the 306th securing ground north of the Japanese defensive lines, the 307th leading a tank-infantry assault on Yigo, and the 305th closing in on Mount Santa Rosa. Once each objective was secured, Santa Rosa would be encircled from Anao to Lumuna Point, leaving the enemy with no escape route except into the sea.
By midday, despite facing delays from the narrow road and enemy sniper activity, Manuel's tanks surged ahead of the infantry, veering right to swiftly eliminate several Japanese machine-gun positions at the road's edge. However, their advance was halted by heavy Japanese fire from the left rear as they crested a slight elevation. In a wedge formation, commanded by Captain Seger from his tank at the right rear, the light tanks swept rapidly over the slight crest. As they pushed on there was an explosion to the left of the tanks directly in front of Seger. He radioed to Colonel Stokes: "There's a burst in front of me; could be mine or antitank gun. Call for the mediums." Just before the mediums came up more explosions sounded from the left. The tankers could not locate the source of the fire because of the dense woods to the left and the absence of flash and smoke. When the mediums reached the open area, their crews could tell that the light tanks were in trouble but they could not see where the fire was coming from. Only when they advanced up the slight rise and began themselves to have steel shrapnel and bullets smash on the left of their hulls and turrets did they turn and pour fire back into the woods at the left rear. Fifty yards behind the stricken tanks the infantrymen struggled to push through the positions by the road that the tanks had overrun. Japanese still fired from a pillbox that had been blasted by the medium tanks as they raced ahead. The troops put rifle and machine-gun fire into it. They threw six grenades before one landed inside the position. The enemy continued to fire from it. A flame-thrower man maneuvered cautiously up to the position and put the searing flame in through an opening. The heat was too much for the defenders; one of them scurried out and fell before the American guns. The enemy position, so skillfully concealed from the front but vulnerable from the rear, was built around two light tanks. Two antitank guns, two 20mm guns, six light and two heavy machine guns, plus about a makeshift battalion of infantry added their fire to make the Yigo defense formidable. One medium was hit in its gas tank. Flames shot out of the bottom and quickly enveloped the sides. The crew hastily clambered out of it just before the ammunition inside began exploding. Another tank stalled under the heavy fire. As bullets hit the vehicle, the tankers dashed for a shell hole. Some of the mediums moved on out of the area. One of them tried to sweep around to the right below the line of enemy fire and promptly threw a track. As more tanks came up, they swung their cannons and machine guns around for brief fire on the enemy positions to the left and then passed on to the objective ahead. The leading light tank had similarly been destroyed and another was destroyed shortly afterwards.
The American armor suffered losses against this well-concealed enemy position. Fortunately, Colonel Smith's 3rd Battalion, encountering minimal resistance in the jungle, directed Company K to flank the Japanese from the rear, catching them off guard and eliminating them without casualties. This enabled the 307th to secure the Yigo area and the elevated terrain to the northeast in readiness for the Santa Rosa assault. Meanwhile, the 306th consolidated west and north of Yigo, while the 305th advanced to the Lumuna Point line. The day also witnessed the inaugural combat flights of Marine planes from the newly completed Orote airfield over Guam. By nightfall, Obata dispatched his remaining tanks on a futile infantry-tank raid against the 306th, which repelled the attack successfully. On August 8, as the 305th and 307th Regiments closed in on Santa Rosa, Smith's forces continued north towards Lulog to complete the encirclement. Although the 306th captured Lulog, the 307th encountered minimal resistance in capturing Santa Rosa. Consequently, Bruce instructed Smith to push north towards Salisbury, but progress was limited by day's end.
On the left flank, Shepherd’s brigade and Turnage’s division continued their advance. The 22nd Marines progressed to Ritidian Point, establishing three roadblocks. The 4th Marines secured O-5 and advanced to RJ 462. The 21st Marines patrolled the Chaguian area, while the 3rd Marines fought through dense jungle to defeat a Japanese roadblock and reach the Salisbury-Tarague Road. Patrols returned late in the afternoon and reported few enemy contacts, but one such unit from 3/21 had discovered a Japanese truck containing the bodies of 30 native men who had been beheaded. According to the official account of the incident, the Guamanians, found near Chaguian, had not been dead more than 24 hours. The next morning another patrol found an additional 21 bodies in the jungle near the same village.
The 9th Marines faced heavy resistance as they dug in around Salisbury, close to Obata’s headquarters. A tank-infantry counterattack targeted Stuart’s 2nd Battalion at night, dispersing the enemy but necessitating retreat due to the threat of Obata’s remaining tanks. Stuart’s 3rd Battalion and Butler’s 1st Battalion attacked the next morning but found no sign of the tanks. Meanwhile, the 77th Division patrolled the Yigo-Salisbury area, and the 9th Marines advanced rapidly towards the northeastern coast before redirecting patrols to Savana Grande, where 3000 Japanese were suspected to be hiding. Following artillery bombardment, the Marines occupied Savana Grande and Pati Point but found little evidence of Japanese presence. Patrols from the 4th and 22nd Marines also reached the northern beaches, leading Shepherd to declare an end to organized resistance in the brigade zone. The last known resistance persisted in the 3rd Marines’ sector, where Obata’s tanks were last observed.
Accordingly, on August 10th, Stuart’s 2nd Battalion initiated an attack to the east, establishing contact with two tanks on the road. Swiftly disabling these tanks, the Marines pressed forward, swiftly overpowering the Japanese positions and successfully seizing a total of seven abandoned tanks. By 11:30, Geiger declared an end to organized resistance on Guam. American casualties up to this point totaled 1214 killed, 5704 wounded, and 329 missing, with 10971 Japanese reported dead. Despite this announcement, Obata persisted at Mount Mataguac, fending off Bruce’s infantry patrols since August 8th. Finally, on August 11th, Smith’s 1st Battalion launched a meticulously planned attack supported by tanks and mortar barrages, stunning the defenders and enabling soldiers to destroy cave entrances. When the caves were reopened four days later, more than 60 bodies, including General Obata’s, were found inside the well-fortified command post. Following the battle, Major-General Henry Larsen’s garrison forces maintained intensive patrols on Guam throughout the remainder of the year under close scrutiny from Island Command.
Island Command, Guam under General Larsen, had taken command of Orote Peninsula and Cabras Island on August 2 to begin base development, namely the airfield and seaport. It then assumed formal command of Guam on August 15. Island Command grew rapidly as it took over all logistics, construction, and civil affairs tasks in stages. It included the 5th Naval Construction Brigade with the 27-29th Seabee Regiments with 12 Seabee, four Army, and one Marine engineer battalions plus "Lion 6", a Navy advance base force responsible for building and operating Naval Operating Base, Guam. Island Command was also responsible for the care of 21000 Guamanian civilians and built replacement housing for 15000. Both the 3rd and 77th Divisions maintained an infantry regiment and an artillery battalion in the north to deal with diehards. Up to 80 Japanese were killed each day during the first two weeks after Guam was declared secure. The nightmare would continue for the Japanese for some time to come. The 3rd Marine Division took over sole responsibility for island defense under Island Command on August 22. The 1st Provisional Marine Brigade then departed for Guadalcanal on August 31, where it would be expanded into the 6th Marine Division to fight on Okinawa. The 3rd Marine Division finally remained on the island to train for Iwo Jima, as did the 77th for Leyte and later Okinawa.An estimated 8500 Japanese soldiers remained scattered in the jungles of the north and the mountains of the south, engaging in guerrilla warfare until the war's conclusion. However, most were either killed or captured before then. The final tally for Guam by August 1945 included 18377 Japanese killed and 1250 captured, with American losses totaling 1407 killed, 6010 wounded, and 376 missing.
By the conclusion of the Marianas Campaign, the Japanese suffered casualties exceeding 50,000, while the Americans solidified their control by positioning themselves strategically along the inner ring of Imperial defenses. This positioning enabled them to cut off the flow of supply ships and submarines that had previously supported remote enemy garrisons. Additionally, the Americans established a naval base with the capacity to support one-third of the Pacific Fleet, set up extensive forward supply depots, which posed a threat of swifter assaults on the Japanese home islands, and constructed several B-29 airfields. These airfields facilitated the unleashing of devastating aerial bombardments on Japan, bringing the full force of total war to its people through a relentless barrage of explosives and fire. That finishes up the story of the Marianas, now we need to travel back over to New Guinea.
Despite the initial success of the Japanese offensive, General Hall's forces successfully halted the enemy advance and reorganized their river line by July 15th, although there remained a 1500-yard gap in the center. Aware of this vulnerability in the American defenses, the Japanese exploited it, particularly under the cover of darkness. However, Colonel Starr's 3rd Battalion actively patrolled this area and occasionally engaged with the enemy, such as the night of July 14th when they eliminated 135 Japanese soldiers. Nonetheless, General Cunningham reported that his South Force had expanded its lines nearly 1000 yards beyond its designated sector without encountering any elements of the 124th Regiment. Consequently, on July 15th, Starr concluded that his regiment had not advanced as far south as previously thought, prompting him to order his units to adjust their positions southward and fortify their defenses along the Driniumor River towards Cunningham's Troop E location.
The next morning, the 3rd Battalion began its journey southward to close the gap. However, upon reaching the area by nightfall, Troop E came under attack from two companies of the 1st Battalion, 239th Regiment. As the cavalrymen sought cover from this assault, Starr’s 3rd Battalion also faced fire from Colonel Nara’s 3rd Battalion, which had redirected southward following its defeat at the Paup villages. This division split the American force, with Companies L and M encountering increasing resistance as they pressed southward towards South Force lines, while Companies I and K fortified their positions for the night. Despite the engagement resulting in the death of several Japanese soldiers and the narrowing of the gap to 500 yards, nightfall on the coast witnessed General Adachi’s Coastal Attack Force launching suicide banzai charges towards Anamo, only to be swiftly repelled by the defenders' lethal machine-gun fire, resulting in the complete annihilation of the force. In the rear, Colonel Howe’s 1st and 2nd Battalions were dispatched by Hall to eliminate remaining enemy units west of the Driniumor. Over the course of two days, in a series of complex and occasionally disjointed company maneuvers, the Americans successfully subdued Colonel Nara’s remaining troops in the area. Meanwhile, further south, Japanese groups were spotted crossing the Driniumor at a fording point approximately 2500 yards south of Afua, prompting Cunningham to deploy Troop A to strategic high ground behind the river to halt westward Japanese movements. There, the 78th and 80th Regiments, led by Major-General Miyake Sadahiko, were gathering in preparation for a fresh offensive.
Adachi devised a fresh strategy, envisioning Miyake's forces striking Afua from the southern front, while the 239th Regiment prepared to advance against the Kawanaka Shima area. Furthermore, the retreating 237th Regiment and the reserve 66th Regiment received orders to head south to reinforce future assaults by the 20th Division, although they wouldn't reach the destination until July 25. Meanwhile, as the Miyake Force gradually maneuvered into position on the right and rear of Cunningham’s 1st Squadron, Starr faced ongoing challenges in filling the gap in the center, eventually managing to close it by the morning of July 18. That night, Miyake finally dispatched two battalions to launch an assault on the 1st Squadron's command post and the adjacent perimeter held by Troop A, successfully pushing them back 250 yards to the northeast. However, swift reinforcements enabled Cunningham to recapture the lost ground the following morning, prompting the enemy to retreat northwest into the jungles. By afternoon, fresh Japanese units had once again encircled the Troop A position; yet, after an effective artillery barrage, the cavalrymen thwarted Adachi’s plans by pushing 600 yards to the southwest. Following this triumph, on July 21, Troop C relieved the battered Troop A; Howe’s battalions successfully established a patrol base on the East Branch of Koronal Creek; and Starr’s 2nd Battalion relocated to Palauru to enhance outer security southwest of the airfield. Concurrently, on July 19, the initial units of General Wing’s 43rd Division commenced landing at Aitape, with the 2nd Battalion, 169th Regiment subsequently assuming control of approximately 1000 yards of the river line on the right flank of the 124th Regiment by July 22.
Meanwhile, Adachi instructed the still-reorganizing Miyake Force to launch another assault on Afua from the north and west, while General Nakai’s 79th Regiment crossed the Driniumor River to strike from the south. On July 21, in the evening, Miyake initiated an attack on Troop C’s position, effectively isolating it from the remainder of South Force. Despite the cavalry's resistance against the intense Japanese onslaughts, Miyake's units successfully thwarted Cunningham’s efforts to relieve the besieged troop in the subsequent days. Faced with the threat to his command post and reluctant to divert more forces from the river defenses, Cunningham ultimately opted to establish a new defensive line 1000 yards north of Afua, consequently abandoning the town and leaving Troop C stranded.
It was not until the night of 21-22 July that the Japanese forward units were able to organize for any sort of attack. During that night, elements of the 124th Infantry received considerable mortar, machine gun, and rifle fire from east of the Driniumor. This fire increased the next morning, and about noon the 3d Battalion, 124th Infantry, was attacked from the west by elements of the 237th Infantry. The first Japanese attack was ". . . finally broken up by a bayonet charge . . ." conducted by elements of the 3d Battalion, 124th Infantry, but other attacks followed as troops of the 1st Battalion, 239th Infantry, tried to move across the Driniumor from the east, striking both the 124th Infantry's unit and part of the 2d Battalion, 169th Infantry. Before dark on the 22d, the 3d Battalion, 124th Infantry, counted 155 new Japanese dead in its area. That unit and the 2d Battalion, 169th Infantry, reported their own losses as five killed and twenty-five wounded.
Despite further unsuccessful attempts to reopen the river crossing by the 1st Battalion, 239th Regiment, Adachi eventually decided on July 25 to dispatch the 41st Division south to reinforce the southern front. Following the fall of Afua, Hall directed Howe’s battalions to depart from their East Branch base and reinforce Cunningham’s South Force, successfully arriving at the new defensive line by July 23. With these reinforcements in place, Cunningham early in the afternoon of the same day decided to deploy Troops A and B to advance westward toward Troop C, while Howe’s 2nd Battalion pushed southeast to support the isolated troop. Despite the lack of coordination in the attack, infantrymen managed to infiltrate Troop C's perimeter from the northwest, aiding in repelling a fierce Japanese assault from the southwest, while the cavalry troops reclaimed Afua and established new defensive positions.
Despite an initial triumph, American efforts to advance on July 24 were thwarted by the resolute defense of the Japanese, who fiercely guarded all paths, trails, and ridges in the densely forested terrain northeast of the perimeter. However, on July 25, Companies E and B under Howe surprisingly made contact roughly 500 yards north of the besieged forces, encountering minimal resistance, which allowed the beleaguered Troop C to retreat. With Troop C relieved, Howe’s units continued their assault southward and westward toward the Afua-Palauru trail, driving the Japanese forces into the Torricelli Mountains. Nonetheless, a significant number of Japanese troops remained within a triangular area delineated by the sloping ground, Afua, and Company G's ridgeline position, persistently harassing Cunningham’s forces. Throughout the night, additional Japanese reinforcements, including the 66th Regiment, maneuvered behind Howe’s 2nd Battalion, securing control over trails leading southeast through dense jungle from the banana patch to a point on the Afua-Palauru trail near the 2nd Battalion's command post. Consequently, on July 26, Howe’s 1st Battalion was withdrawn toward the sloping ground, with the 2nd Battalion expanding its positions to the east to cover the vacated area. On July 27, the battalion launched a successful southward attack; however, menacing Japanese movements to the west compelled the American forces to withdraw, despite other units under Cunningham also repelling enemy advances. Subsequently, Cunningham reorganized his lines on July 28 to strengthen defenses, anticipating imminent large-scale Japanese assaults. Nonetheless, on July 29, the 1st Squadron and the 2nd Battalion renewed their offensive toward the south and west into the Triangle, yet this time Adachi’s determined defenders successfully rebuffed them.
Therefore, local patrol activity was the primary focus on July 30 and 31 while Cunningham devised plans for another offensive into the Triangle. Major combat activity revolved around the withdrawal of Company G, 127th Infantry, from its exposed outpost west of Afua. On the afternoon of the 29th the unit had been driven more than 400 yards east of its original position by Japanese attacks and had established new defenses on high ground about 300 yards west of Afua. On the 30th the company was surrounded and spent all day fighting off a series of small-scale attacks. The next morning it fought its way north to the dropping ground, where it arrived about 1330. Thence, it moved on to the Driniumor and joined the rest of the 2d Battalion, 127th Infantry, which had switched positions with the 3d Battalion.
During the period from 13 to 31 July, South Force had suffered almost 1,000 casualties, of which 260 had been incurred by the 112th Cavalry. For the understrength cavalry regiment, this was a casualty rate of over 17 percent. The 2d Battalion, 127th Infantry, had also lost heavily and was in need of rest, reorganization, and re-equipment--needs which had prompted General Cunningham to change the places of the 2d and 3d Battalions, 127th Infantry. South Force casualties were as follows: 106 killed, 386 wounded, 18 missing, and 426 evacuated as a result of disease and sickness. South Force estimated that it had killed over 700 Japanese.

With the capture of Guam, the Marianas campaign had finally come to an end. Yet it seemed apparent to the frontline commanders, the closer the island hopping got to the Japanese home islands, casualties were exponentially mounting. How much American blood was it going to take to end the Pacific War?

- 141 - Pacific War Podcast - Battle of Sansapor July 30 - August 5, 1944
30 7月· The Pacific War - week by week
Last time we spoke about invasion of Guam and Tinian. Japanese forces, led by General Obata on Guam and Colonel Ogata on Tinian, prepared defenses with trenches, pillboxes, and artillery. The Americans bombarded these defenses extensively. Despite resistance, they successfully landed on Guam and Tinian, securing beachheads. Intense fighting ensued, with Marines facing heavy casualties. Despite Japanese counterattacks, American forces gradually expanded their footholds, leading to the eventual containment of the Japanese on Orote Peninsula. The Japanese launched a fierce assault against Marine positions on Guam, engaging in close combat with heavy casualties on both sides. Despite initial success, the Japanese offensive was repelled by intense artillery and machine-gun fire, leaving the remaining enemy forces to defend Orote Peninsula. On Tinian, after extensive naval bombardment, Marines landed successfully, repelling Japanese counterattacks and establishing a beachhead. Despite heavy Japanese casualties, the Marines suffered relatively few losses, ultimately breaking the enemy's resistance.
This episode is the Battle of Sansapor

Following the successful capture of Noemfoor and Biak, the Allies possessed ample air and supply bases to advance to the Vogelkop Peninsula, fulfilling General MacArthur's aim of establishing a vital airbase supporting further operations northwestward, potentially towards Mindanao or via Halmahera. Initially considering Manokwari as a non-critical objective, MacArthur's plan centered on seizing Sorong and Waigeo Island for crucial supply and air bases in New Guinea. However, the rapid pace of Pacific theater operations raised doubts about the feasibility of bringing the Klamono oilfields into production before the war's end, prompting the cancellation of exploitation plans by the Joint Chiefs of Staff.
The Joint Chiefs assumed responsibility for the direction and coordination of oil rehabilitation projects in the Dutch East Indies and undertook necessary liaison with British and Dutch agencies. By mid-February 1943 they had decided that military units would at least start all oil rehabilitation and exploitation projects in the Indies, although the final development of the oil resources might be left to civilian agencies. MacArthur was instructed to plan the location and timing details of oil rehabilitation projects in the Indies, and, subject to the Joint Chiefs' approval, execute those plans. At the same time, the Joint Chiefs directed that the organization of special military petroleum production and refining units begin. The requisite troops, most of them US Army engineers and many especially recruited from civilian pursuits, soon began to assemble and train in California. Orders were also placed with manufacturers for the special production and refining equipment, which was sent to California as it was obtained. While these steps were being taken to coordinate oil rehabilitation projects, it had become obvious that in accordance with MacArthur's plans the first significant oil producing region that could be recaptured in the Netherlands East Indies would be the Klamono district on the Vogelkop Peninsula. The Klamono oil was especially valuable in that it could be used as fuel for naval vessels without refining beyond a little "topping" to remove excess naphtha. With limited effort, the wells could be expected to bring in some 16000 barrels of crude oil per day; with additional development, about 25000 barrels. Such production would presumably save the Allies considerable shipping space and time, for, instead of the long haul from United States ports, navy bunker fuel could be produced and topped as necessary much nearer to the scene of combat.
With the oilfields no longer a priority and aerial surveys indicating unsuitable conditions for airstrips on Waigeo, MacArthur opted for ground reconnaissance of the Mar-Sansapor area. This exploration revealed promising landing beaches and potential airfield sites, albeit requiring significant effort to develop. Consequently, MacArthur directed Alamo Force to secure the lightly-defended Sansapor-Mar area instead of Sorong-Waigeo, scheduling a landing for July 30. General Krueger tasked General Sibert’s 6th Division with Operation Typhoon, designating the 20th Regiment at Wakde-Sarmi as reserve and arranging relief by Major-General John Persons’ 31st Division.
Admiral Fechteler’s Task Force 77 had devised a strategy: to deploy Colonel Forbie Privett’s 1st Regiment, consisting of the 1st and 2nd Battalions, onto the Red Beaches northeast of Mar. Concurrently, Sibert’s 6th Cavalry Reconnaissance Troop was tasked with securing Middleburg Island. Following the landings, airfields were to be constructed at these sites. The subsequent phase involved Privett’s 3rd Battalion executing a shore-to-shore movement to establish a PT base on Sansapor’s Green Beach, scheduled for the day after the initial landings.
To set this plan in motion, the 31st Division commenced unloading operations at Maffin Bay on July 14 and successfully relieved Sibert’s units four days later. The two regimental combat teams of the 31st Division, the 155th and the 167th, which operated at Wakde-Sarmi had no previous combat experience but received much valuable training in a series of patrol actions, company-sized scouting missions, and battalion reconnaissances in force. General Persons wanted to mount an offensive to drive the Japanese from a main line of resistance which they had established in the low hills between Metimedan Creek and Sarmi, but the demands for labor at the Maffin Bay staging area and the necessity for committing many troops to the defense of that area made it impossible to assemble sufficient strength for such an attack. Then, by the time the 6th Division's requirements had been met, the 31st Division itself had to begin preparations for another operation. The 31st Division therefore had to confine itself principally to its patrolling missions, both west and east of the perimeter. Patrols east of the perimeter were sent out to hunt down stragglers from the Japanese Hollandia garrison, and most of them, comprising armed natives of the Wakde-Sarmi area, were led by a Dutch officer, 1st Lt. C.J. Sneeuwjagt. Meanwhile, work went on at the Maffin Bay staging area; and during the period July 18-August 31 a daily average of 2,500 tons of various supplies was unloaded at the bay. During the same period the 31st Division lost 39 men killed, 195 wounded, 34 injured, and 3 missing. The division in turn killed 294 Japanese, found 497 dead, and captured 14 others.
However, the deployment of the 6th Division faced delays due to heavy congestion in the Wakde-Sarmi area. It wasn’t until July 27 that Sibert’s combat units began departing from Maffin Bay towards Sansapor. Maintaining the element of surprise was paramount to General Krueger, hence no preliminary naval or air bombardment was conducted in the Sansapor-Mar area. Instead, General Kenney’s aircraft targeted Japanese bases at Manokwari, Sorong, and the Halmahera-Ceram-Ambon region.
To further deceive the Japanese, Fechteler’s convoy took a circuitous route to approach Sansapor, apparently arriving undetected around 05:00 on July 30. As anticipated, no opposition was encountered, and the first wave successfully landed at 07:01. While Privett’s troops swiftly unloaded on the mainland, one LST proceeded toward Middleburg Island. By 07:30, it began deploying the amtracs carrying the reinforced 6th Cavalry Reconnaissance Troop, which safely landed by 08:00. Encountering no resistance, the island was promptly secured, and the troop regrouped before setting sail for nearby Amsterdam Island, which was also secured unopposed by 11:30.
Upon returning to the mainland, following the incident where three unarmed Japanese were killed, Privett’s 2nd Battalion proceeded inland and eastward. They successfully established defenses along low hills roughly 800 yards from the shore. Meanwhile, the 1st Battalion encountered challenges navigating through dense jungle undergrowth. At 07:40, the 3rd Battalion landed and moved west along the beach to the Wewe River mouth, preparing for the next day's advance to Sansapor. By nightfall, all units were ashore, securing the desired beachhead perimeter. The following day, Privett’s 3rd Battalion embarked for Green Beach at Cape Sansapor, meeting no resistance upon landing at 08:44. They then proceeded south along the beach to secure Sansapor Plantation and Village by 10:00. While Cape Sansapor proved unsuitable for the planned PT boat base due to reef-bound shorelines and poor beaches, Amsterdam Island emerged as a promising alternative location. Subsequent operations in the Sansapor-Mar area involved patrolling to eliminate scattered Japanese groups, expanding the beachhead, and safeguarding airfield installations. A significant event occurred on August 3 when 92 sick or wounded Japanese and Formosan troops were captured at a Japanese hospital near Cape Opmarai. Concurrently, General Anami acknowledged the untenable positions on the northeastern Vogelkop and General Ikeda’s 35th Division abandoned Manokwari on July 16, embarking on a challenging overland march towards Sorong with limited supplies. Around the same time, General Teshima’s headquarters at Manokwari and other small garrisons in the region commenced an overland journey to Windehsi.
By August 15, as units of the 35th Division approached the Kor River, the 63rd Regiment moved into the vicinity, engaging in skirmishes with retreating Japanese forces. In these encounters, they eliminated 17 enemy combatants and captured 4. By August 31, the 63rd Regiment had further success, neutralizing 155 Japanese soldiers and capturing an additional 42, with minimal losses on their own side: 3 soldiers killed and 4 wounded. Similarly, patrols from the 1st Regiment on the western flank encountered retreating Japanese forces, resulting in the elimination of 197 enemies and the capture of 154, with only 4 soldiers wounded by the end of August. The total casualties for the Typhoon Task Force amounted to 14 killed, 35 wounded, and 9 injured, while they managed to account for 385 Japanese and Formosans killed and 215 captured. Ikeda’s division remnants reached Sorong on August 25 after enduring a grueling 40-day march. Additionally, construction of the Middleburg strip was successfully completed by August 14, and the Mar Drome was slated to be operational by September 3 to accommodate Kenney’s fighters and medium bombers.
Transitioning to Tinian, following the successful landing on July 24 and the subsequent destruction of the Japanese counterattacking force, General Schmidt's primary objectives for July 25 included landing the 2nd Marine Division and expanding the beachhead. While General Watson’s Marines disembarked swiftly, General Cates’ 4th Marine Division initiated their advance at 10:00. Colonel Jones’ 23rd Marines navigated through dense canefields and underbrush along the coast beyond the O-1 Line. Colonel Batchelder’s 25th Marines executed an enveloping maneuver against Mount Maga, securing its summit after intense combat supported by mortars and tanks. Colonel Hart’s 24th Marines swiftly moved south and eastward, reaching the O-2 Line.
Upon arrival, Colonel Wallace's 8th Marines assumed control of the far left flank and proceeded slowly through the rugged coastal terrain and dense undergrowth toward Ushi Point. Following the successful capture of a Japanese stronghold, the Marines advanced unopposed, advancing 200 yards past O-2 swiftly. However, the day brought hardship for the 14th Marines, facing heavy counter-battery fire resulting in the loss of 13 soldiers killed and 22 wounded. Admiral Mitscher's Task Force 58 conducted a reconnaissance-in-force of the western Carolines and launched a third raid on the Volcano-Bonin Islands to thwart enemy bomber interference, resulting in the destruction of five ships, damage to others, and the loss of 13 enemy planes for only 16 aircraft lost. The next day, Schmidt's undermanned divisions, later reinforced with 1782 replacements to fill Saipan-related gaps, commenced the advance to the O-3 Line. While the 23rd Marines steadily advanced with minimal resistance towards the vicinity of the O-4 Line, the bolstered 25th Marines cleared Mount Maga and, securing the summit of Mount Lasso, advanced into the O-4A Line virtually unchallenged. Meanwhile, the 8th Marines rapidly secured the Ushi Point flats and its airfield, Colonel Stuart's 2nd Marines swiftly advanced eastward, securing Asiga Point upon reaching the east coast by 12:30, and Colonel Riseley's 6th Marines, after landing, pushed southward to establish a line abreast of the 2nd Marines.
On July 27 and 28, encountering minimal opposition, the Marines advanced southward in a concerted effort, with riflemen in formation and skirmishers leading the way. The NTLF G-2 Lieutenant Colonel Thomas R. Yancey came to a conservative conclusion on July 27 that summarized not only that day's enemy situation but the entire operation's enemy situation as well: “Without saying so, he seemed to indicate the importance of all units conducting aggressive patrolling far to the front: To date there have been no indications that our front line units have encountered the 50th Infantry Regiment in force [since the first night's counterattacks]. It is believed that this unit is largely intact and it is known that they are well equipped and seasoned troops. They are capable of intervention at any time and may be expected to offer a strong opposition when encountered.” In the same report, Yancey noted that the "most likely enemy capability" was: "To fight a delaying action, withdrawing to, and organizing further defenses in, the high ground in the southeastern end of the island." Faced with this enigmatic enemy situation, General Schmidt formulated his scheme of maneuver and assigned his objectives on July 27 and 28 to facilitate an irregular "elbowing" advance. From the front lines held on the morning of July 27, Objective O-4 was near for the 4th Division, far for the 2nd Division; once Objective O-4 had been reached, the emphasis would shift--Objective O-5 would be near for the 2nd Division, far for the 4th Division. The Corps' attack on these two days, then, would find the 2nd Division carrying the ball on July 27, the 4th Division on the 28th. On the first day the 2nd Division would push forward at 07:30, the 4th Division at 10:00; on the second day the 4th Division would attack at 07:00, the 2nd Division at 10:00. Variations in these attack hours were consistent with plans to punch first with the left, then with the right. Principal advantage of this arrangement was that the bulk of the supporting fires could be allotted first to one division, then to the other. Not only did the 14th Corps Artillery mass its fires to support the main effort, but two 105mm howitzer battalions of the division executing the secondary attack were also made available to support the principal thrust in each case.
Despite the gradual progress made by Cates’ Marines as they secured key positions on higher terrain, they successfully reached the O-4 Line by the end of the first day. Simultaneously, Watson’s Marines made significant strides on more favorable terrain, aided by tanks, covering a distance of 4000 yards to also reach the O-4 Line. The following day, amidst worsening weather conditions, the 2nd and 6th Marines quickly moved forward to secure the O-5 Line. The weather at Tinian had been unpleasant. Nearly every day featured rain squalls, gusty winds, and ominous clouds. And yet, for Jig-Day and three days following, the seas remained calm enough for reasonably convenient shore activities. The "three days of good weather" that Admiral Hill had considered vital had already expired. On the afternoon of 28 July the weather got worse--much worse. This condition resulted from the effects of a typhoon that built up west of the Marianas and sent its swells and winds against Tinian's west coast. The seas surrounding Tinian changed to a dirty gray-blue as the winds mounted and the waves boiled over one another and grew into larger, uglier masses. Surf roaring against the tiny WHITE Beaches and their rocky flanking shelves forced temporary suspension, at 1800 on 28 July, of all unloading over the beaches.
On the left flank, after intense artillery bombardment, Cates’ Marines swiftly advanced to the O-5 Line, then, supported by naval forces, resumed their march to secure Gurguan Point and its airfield, advancing to the intermediate O-6A Line, with Jones’ 23rd Marines covering a total distance of 7300 yards. On July 29, with half of the island under control, Schmidt directed his forces to push beyond the O-6 Line. Accordingly, the 24th and 25th Marines advanced with minimal resistance and reached the O-6 Line. Although Watson’s Marines faced initially light opposition, resistance intensified as they crossed the O-6 Line. The 6th Marines managed to secure advantageous positions just shy of the intermediate O-7A Line, while the 2nd Marines encountered opposition around the Masalog Point hill, halting their progress. The next day, Cates’ Marines resumed their southward advance, encountering resistance from Japanese machine-gunners and riflemen entrenched in coastal caves.
While tanks engaged the enemy, the 24th and 25th Marines surged forward, effectively securing Tinian Town and its airfield, and eventually reaching the O-7 Line. On the right flank, Watson’s Marines also pressed southward, with the 2nd Marines swiftly securing Masalog Hill and advancing along the coast despite heavy machine-gun fire, reaching O-7, while the 6th Marines advanced against sporadic resistance, also reaching O-7. Additionally, the 8th Marines took position at the center of the corps’ line. With the capture of four-fifths of the island and over 3000 Japanese either killed or captured, Schmidt’s Marines successfully pushed the remaining Japanese forces under Colonel Ogata’s command into an unnamed ridge between Lalo and Marpo Points at Tinian's southern end.
On July 31, following a massive artillery, air, and naval barrage, the Marines launched another assault to the south. The 24th Marines made significant progress along the coast and on less steep cliffs, securing the road to the ridge top. The 23rd Marines faced stiffer resistance but advanced with remarkable discipline, aided by tanks, gaining high ground. On the right flank, the 2nd and 6th Marines advanced against light machine-gun and mortar fire, reaching the intermediate O-8A Line. In the center, the 8th Marines encountered stronger resistance but managed to establish a foothold on the zigzag road to the top. By nightfall, a 600-yard gap emerged between the 8th and 23rd Marines, which the Japanese could exploit.
At 23:00, a banzai charge was repelled; however, at 01:00 on August 1, a 150-man force blocked Wallace’s rear road and launched an attack. A counterattack force was quickly organized, driving back the enemy. Ogata's final banzai charge at 05:15 was directed at the left of Company E but failed to breach Marine defenses. Both Colonel Wallace and the enemy commander probably still Colonel Ogata had realized the tactical implications of the cliff-line penetration. Both knew that it provided a route over which thousands of Marines could move into the Japanese rear. The two commanders' reactions were classic. As soon as one of his battalions grasped a toe hold, Wallace exploited the success by committing his reserve there. The enemy commander, as soon as he received word of the penetration, ordered a counterattack to throw the Marines off the cliff and restore the position. Each selected a tactically sound course of action. Only one could be successful.
At dawn, as the Japanese began to withdraw, Cates’ Marines continued the attack southward, with the 24th Marines reaching the O-8 Line at Lalo Point, and the 23rd Marines, after encountering a sheer cliff, retracing their steps to reach the cliffline in front of O-8. On the right flank, the 8th Marines swiftly advanced to O-8A and moved alongside the 6th Marines toward the cliffs overlooking the water. Finally, the 2nd Marines secured the high ground to prevent enemy escape along the east coast. Despite not reaching Marpo Point, organized resistance crumbled, leading Schmidt to declare Tinian secure at 18:55.
Organized resistance had ceased. But on the early morning of August 2, an enemy force–estimated variously from 100 to 250–struck headlong into the command post of the 3rd Battalion, 6th Marines. Headquarters personnel, armed for the most part with carbines and pistols (although two automatic rifles were also used), considered the enemy group very well "organized." Initially, personnel of the aid station bore the brunt, but soon everyone in the headquarters group–clerks, communicators, corpsmen, assault engineers, mortarmen, and staff personnel–rallied behind their commanding officer, Lieutenant Colonel Easley, to defend themselves. The Japanese, carrying rifles, grenades, and machine guns, hurled themselves at the Marines with characteristic violence. As soon as one fell, another took his place. In search of substantial assistance, Captain John R. Steinstra, Headquarters Company commander, dashed to the nearby Company F, 6th Marines, acquired a medium tank and a rifle platoon, and led them back to the fight. Here was welcome reinforcement to the 3rd Battalion Headquarters Group, which had fought the enemy at close quarters for over two hours. The machine barged into the battle with guns blazing, and the tide turned. The battalion executive officer later stated that he considered the tank's appearance "vitally important" to the outcome. Those enemy soldiers who remained on their feet hastily departed the area. Daylight made results of the enemy effort visible: 119 Japanese bodies lay almost side by side in and around the 3rd Battalion command post. But the Marines had also taken casualties, one of the dead being Colonel Easley.
Nearly 400 Japanese perished in the week following the island's capture. From August 7 onward, the 8th Marines conducted cleanup operations on Tinian until January 1, 1945, eliminating an additional 542 Japanese at the cost of 38 killed and 125 wounded. Throughout the Battle of Tinian, a total of 5,745 Japanese were killed and 404 captured, while American losses amounted to 389 killed and 1,816 wounded. Similar to Saipan, around 4,000 civilians either took their own lives or were killed, but unlike Saipan, the majority—approximately 13,000 civilians—were interned.
On April 15, 1944, there were 16,029 civilians residing on Tinian, out of which 1,658, primarily consisting of women, children, and the elderly, were relocated to Japan prior to the American invasion. Approximately 2,610 civilians lost their lives during the conflict. Journalist Robert Sherrod observed that most casualties occurred due to direct combat, as the Americans heavily utilized artillery, aerial bombardment, and naval attacks, often forcing civilians to seek refuge alongside soldiers. Some perished from diseases, thirst, or hunger. Tragically, some were also victims of atrocities committed by Japanese soldiers, such as being tied together and attacked with grenades. Instances of mass suicide occurred, notably at the "Suicide Cliff," where parents threw their children off the 120-foot precipice, and some civilians were pushed by Japanese soldiers. According to a captured Japanese soldier, a large group willingly perished in caves at the military's behest. By August 1, only 2,468 civilians had been documented, but within three days, this number surged to 8,491. The 2nd Marine Division established a camp for civilians at Ushi Point Airfield, while the 4th Marine Division set up another at the ruins of Churo village, which became a permanent settlement for all displaced civilians. By October 15, Camp Churo housed 10,926 civilians, comprising mainly Japanese and Korean nationals, with nearly half being children under 15 years old. The military administration struggled to provide adequate care due to shortages of relief supplies. Seabees oversaw the construction of temporary shelters initially, which were later replaced by more durable structures using salvaged materials. The internees also supplemented their provisions by salvaging food and cultivating gardens, with Seabees stepping in to provide improvised diesel stoves as firewood became scarce. In late 1945, Admiral Spruance, who succeeded Nimitz as CINCPOA, ordered the repatriation of all Japanese and Korean civilians, a process completed by late 1946.
Shifting focus to Guam, by July 25, General Geiger's Marines had secured two beachhead areas, with General Turnage's 3rd Marine Division advancing on the Fonte Plateau and General Shepherd's brigade sealing off the Orote Peninsula. Despite a fierce enemy counterattack on both fronts, Japanese resistance was effectively shattered. On July 26, while mop-up operations continued in General Turnage's sector, General Shepherd's Marines prepared to assault Orote. Following coordinated air, naval, and artillery bombardment, the 4th Marines launched their attack at 07:00, making swift progress. However, the 22nd Marines faced delays due to enemy artillery fire, necessitating the 4th Marines to extend their line to cover the exposed flank. Although the mangrove swamp hindered Colonel Schneider's Marines, they successfully cleared the area by afternoon, establishing contact with Colonel Shapley's forces at RJ 15, albeit with a slight eastern bend in their line. Meanwhile, Shepherd's units encountered mines, pillboxes, and bunkers, halting their advance by nightfall.
On the morning of July 27th, the offensive recommenced, yet the 4th Marines encountered difficulties in penetrating the robust enemy defenses without tank support. However, once the mines were cleared, the Shermans neutralized enemy positions, enabling the Marines to take control of the ridge ahead, although they couldn't advance further through the coconut grove. Meanwhile, the 22nd Marines, moving alongside Shapley’s 3rd Battalion along the inland road, faced delays due to the swamp. They encountered numerous obstacles including pillboxes, trenches, dugouts, and mines near the old Marine Barracks. Remarkably, the determined enemy abandoned their fortified line around 5:00 PM after a substantial bombardment, allowing Schneider’s Marines to swiftly advance ahead of the 4th Marines and seize strategic terrain by nightfall.
Following another intense bombardment, Shepherd’s forces prepared to attack on July 28th. Despite Japanese resistance, Schneider’s tank-supported advance reached the O-4 Line by 10:05 AM, creating a significant gap between Marine regiments. Nonetheless, the 22nd Marines persisted, fighting through the Marine Barracks and halting just 100 yards east of Sumay. Meanwhile, the 4th Marines faced slow progress and fierce opposition, stopping within 150 yards of the airfield. On June 29th, Shepherd launched a final assault after yet another heavy barrage, with both regiments successfully advancing the entire length of the airstrip against minimal resistance, establishing a defensive line 150 yards beyond the strip by 2:00 PM.
As the 22nd Marines redirected their efforts to clean up the devastated Sumay area, effectively eliminating the last remaining enemy stronghold the next day, the 4th Marines continued their advance northward, with a combined tank and infantry patrol reaching the tip of the peninsula. With the peninsula now under control, the American flag was once again raised over the ruins of the Marine Barracks.General Shepherd proclaimed “On this hallowed ground, you officers and men of the 1st Marine Brigade have avenged the loss of our comrades who were overcome by the numerically superior enemy three days after Pearl Harbor.” Orote saw over 2500 Japanese casualties, while Marine losses amounted to 115 killed, 721 wounded, and 38 missing.
Moving northward, following a failed Japanese counterattack, Takashina’s forces were preparing to retreat further into the island's interior, but the Americans were relentless in their pursuit. After regrouping and subjecting the enemy to heavy bombardment, battalions from Turnage’s regiments launched an assault towards the Fonte Plateau on July 27, albeit encountering stubborn resistance from the still-active enemy. Meanwhile, Colonel Butler’s 3rd Battalion successfully advanced to the D-2 Line on the same day. Following successful defense against several small-scale enemy counterattacks overnight, Turnage initiated the main push towards the objective beachhead line on the morning of July 28.
The depleted 3rd Marines, with Colonel Craig’s 2nd Battalion attached, launched another assault, encountering minimal resistance and securing the D-3 Line by afternoon, thereby completely controlling the abandoned Fonte area. Further bolstered by the 3rd Battalion, 307th Regiment, the 9th Marines made progress in their attack towards the strategic Chachao-Alutom-Tenjo ridgeline, marking a significant initial victory. Simultaneously, the 2nd Battalion, 307th Regiment, supported by units from the 305th Regiment, advanced towards Mount Tenjo from the south.
Under the protective cover of artillery neutralization fire, Craig’s 3rd Battalion effectively demolished a concrete emplacement at the center of Mount Chachao’s summit and swiftly secured the beachhead line adjacent to Mount Alutom. Simultaneously, General Bruce’s infantry units swiftly captured Mount Tenjo, with Craig’s 1st Battalion joining them by day's end. The 21st Marines faced minimal resistance, eliminating remaining enemy pockets around the radio towers and reaching the designated beachhead line. Thus, Turnage’s attack objectives were achieved, extending the beachhead line across the entire front. Additionally, the 21st Marines overran the 29th Division command post near the Fonte River, resulting in Takashina's demise as he supervised his retreating units. Consequently, General Obata assumed direct command of the remaining forces, adhering to Takashina’s plan for a strategic withdrawal to Mount Santa Rosa, with delaying positions established at Finegayan and Mount Barrigada. The Japanese launched eleven localized counterattacks against Turnage’s beachhead line on July 29, all of which were successfully repelled, inflicting 800 casualties on the attackers. The 3rd Marine Division then focused on consolidation and reorganization for the remainder of the day while rear areas were cleared of enemy presence. In the meantime, as the 306th Regiment secured the unoccupied Mounts Alifan and Taene, Bruce had also dispatched several patrols to the southern end of the island since July 27, successfully discovering by the end of July that the sector had been completely abandoned.

26 7月· The Pacific War - week by week
Last time we spoke about beginning of the bombing campaign against Japan. The Japanese 11th Army faced setbacks at Hengyang due to resilient Chinese defenses and supply shortages. Reinforced by General Xue Yue, Chinese forces launched effective counterattacks, regaining some territories before being pushed back. By July 20, the Japanese resumed their offensive but faced heavy resistance and were paused. American air raids on Japan and Manchuria intensified under General Arnold’s orders, despite logistical challenges. In Burma, Allied forces under General Stilwell made slow but steady advances, capturing strategic positions and repelling Japanese counterattacks. The Chindits, severely depleted, were eventually evacuated. In Yunnan, Chinese forces encircled and assaulted Japanese positions, achieving significant gains despite heavy resistance and logistical issues.

Today our week begins with the ongoings of Operation Forager. By late July, American plans for the invasions of Guam and Tinian were finalized. General Cates’ 4th Marine Division was assigned to land on Tinian’s White Beaches, while General Geiger’s 3rd Amphibious Corps planned two amphibious landings nearly seven miles apart to trap the Japanese in a double envelopment. General Obata, who had relocated his headquarters to Guam, commanded several troops on these islands. On Tinian, Colonel Ogata Keiji's forces included the 50th Regiment, the 1st Battalion of the 135th Regiment, the tank company of the 18th Regiment, and the 56th Naval Guard Unit, totaling 8,039 men. Similar to Saipan, he divided Tinian into three sectors, with most troops defending Tinian Town and Asiga Bay. The 1st Battalion of the 135th Regiment, supported by Ogata’s artillery, formed the Mobile Counterattack Force, ready to respond swiftly to landings. This left only Ogata’s 3rd Company to defend the northwest coast where the Americans planned to land.
Meanwhile, General Takashina’s 29th Division was assigned to Guam and reinforced by Major-General Shigematsu Kiyoshi’s 48th Independent Mixed Brigade and Colonel Kataoka Ichiro’s 10th Independent Mixed Regiment. Takashina’s units fortified the landward neck of the Orote Peninsula and established strong positions on the beaches of Agat, Asan, Tumon, and Agaña Bays. The main fortified area ran along the west coast from Tumon Bay to Facpi Point and included, of course, Orote Peninsula. Other fortified beaches, on the south and east coasts from Merizo to Pago Bay, had been abandoned before W Day, their defenders having moved to the north. Outside the main fortified area, the airfields were provided local defense by anti-aircraft and dual-purpose guns. The most notable and certainly the most effective fortifications on the island were constructed across the neck of Orote Peninsula, which contained a fairly elaborate system of trenches and foxholes arranged in depth, together with large numbers of pillboxes and heavy-caliber weapons. Outside of Orote, the prepared defenses were generally hastily constructed and often incomplete. The typical beach defense was arranged, from the seaward side, in four parallel lines: first were obstacles and mines on the fringing reef offshore; second came beach obstacles and tank traps; third were trenches, machine-gun positions, pillboxes, heavy weapons, artillery, and coast defense guns on the beaches or immediately inland; and, finally, came the machine-guns, heavy weapons, and artillery emplaced on the high ground inland. Insufficient advantage was taken of the high ground, and except on Orote little provision was made for defense in depth. Even as late as the five-week period of pre-invasion bombardment, the Japanese continued to work frantically on improving offshore obstacles and beach defenses, to the neglect of positions in the rear.They also had three tank companies in reserve to strike the beachhead alongside the infantry. Additionally, the 54th Naval Guard Unit, equipped with coastal defense and anti-aircraft guns, secured many positions with reinforced concrete.
The Japanese set up specific defense sectors on this island. Shigematsu’s brigade and Colonel Ohashi Hikoshiro’s 18th Regiment held the Asan Beaches and the Agaña and Tumon Bays. Colonel Suenaga Tsunetaro’s 38th Regiment defended the Agat Beaches, while Kataoka’s forces manned the southern defenses. Additionally, Takashina had a mobile reserve behind the Fonte Plateau, which included five infantry companies, one naval unit, and one tank company. Only Ohashi’s 2nd Battalion was positioned at Guam’s northern end, while Kataoka’s 1st Battalion was deployed to Rota Island. The Americans conducted the longest preliminary air and sea bombardment of the war against Guam, beginning on June 16 after the invasion of Saipan. This bombardment intensified after July 8, when American warships launched the greatest single naval bombardment program of the war, coordinated with Admiral Mitscher’s carrier aircraft. Over the next 13 days, a total of 836 rounds of 16-inch, 5422 of 14-inch, 3862 of 8-inch, 2430 of 6-inch, and 16214 of 5-inch shells were fired at Guam’s main defenses.
At the invasion of Roi-Namur Admiral Conolly had earned the sobriquet "Close-in Conolly" for his insistence that warships cruise close to shore when firing at land targets. At Guam, he reaffirmed his right to the title, but more important was the systematic procedure he introduced for coordinating naval gunfire and aerial bombardment and checking the results of each. A target board of six officers, representing the air, gunnery, and intelligence sections of the staff, was set up to assign primary missions for air strikes and naval gunfire and assess the damages daily before designating the next day's targets. Aerial photographs were taken each morning and on the basis of these damage was assessed and new targets were assigned. In these operations, the admiral's staff was aided by the presence aboard Appalachian of General Geiger who, as commanding general of the landing force, naturally had the greatest personal concern about the accuracy both of the bombardment and of the damage reports submitted afterward.
In the final three days before the landing, Mitscher’s planes conducted 1430 bombing sorties and 614 strafing attacks, dropping a total of 1131 tons of bombs, depth charges, and rockets, while losing only 16 aircraft. Despite the extensive bombardment, positions reinforced with coral and concrete remained in good condition. Anti-aircraft artillery and harbor installations suffered minimal damage, power installations in caves were unharmed, and communications were not interrupted.
The intensity of the attacks on the western defenses suggested a likely amphibious landing there, prompting Takashina to abandon the ineffective southern and northern defenses. Meanwhile, Conolly's vessels, carrying Geiger's Southern Landing Forces, departed Eniwetok for Guam between July 11 and 18, arriving successfully by July 21. Between July 14 and 17, three underwater demolition teams scouted the landing beaches, and under the protection of LCI gunboats, they removed 640 obstacles from the Northern Beaches and 300 from the Southern Beaches. On the morning of July 21, in excellent weather conditions, the Americans began a preliminary bombardment. Admirals Conolly and Reifsneider directed the shelling of Asan and Agat beaches, respectively, while Admiral Mitscher’s carrier aircraft bombed and strafed the fourteen miles of coastline from Agaña to Bangi Point. At 07:40, the assault waves crossed their departure lines under the cover of rocket fire from LCI gunboats. Eight minutes before landing, when the vehicles were 1200 yards from shore, Conolly's warships launched a final massive bombardment, and Mitscher’s fighters provided covering strafing attacks. These attacks were to be shifted inland as the troops approached the shore. Despite the intense bombardment from ships and aircraft, the Japanese managed to target the assault waves, destroying nine amtracs from the 3rd Marine Division. Nevertheless, the waves of vehicles advanced, and at 08:28, the first LVTs landed, two minutes ahead of schedule. Further south, shore fire was even heavier, hitting one LCI gunboat and destroying 13 amtracs. However, the landing formation held, and the troops landed on schedule.
Despite numerous concrete pillboxes still manned by the Japanese, both assault regiments advanced rapidly. Colonel Merlin Schneider’s 22nd Marines successfully captured Agat amid strong resistance but were eventually halted at a hill position northwest of the town. Meanwhile, Lieutenant-Colonel Alan Shapley’s 4th Marines cleared Bangi Point and Hill 40, setting up a roadblock supported by five tanks on Harmon Road. By the end of the day, General Shepherd had established a beachhead approximately 1300 to 2300 yards deep, at the cost of around 350 casualties and 24 lost LVTs.
At 08:30, the infantrymen of Lt. Col. Robert D. Adair’s 2nd Battalion were climbing down cargo nets from their transports into the bobbing landing craft that were to carry them to the edge of the reef. By 10:30 all boats were in position near the line of departure waiting for the signal to go in. For three and a half hours they circled impatiently. At last, at 14:05, came the message to proceed to the beach and assemble in an area 300 yards inland from Gaan Point. Unfortunately, no amphibian tractors were on hand to transport Adair's men over the reef and onto the shore line, and of course their LCVPs were too deep-drafted to negotiate either the reef or the shallow waters inland of it. Over the sides of their boats the men climbed, and waded the rest of the way in water at least waist deep. Some lucky few were able to pick up rides in Marine LVTs on the landward side of the reef, but most stumbled in over the rough coral bottom, cutting their shoes en route and occasionally falling into deep potholes. Luckily, no enemy fire impeded their progress, and except for the dousing they got and the exhaustion they suffered the troops of the 2nd Battalion, 305th Regiment completed their ship-to-shore movement without injury.To the north, Colonel Edward Craig’s 9th Marines advanced steadily against fairly heavy machine-gun and rifle fire, securing a beachhead about 1500 yards deep. Colonel Arthur Butler's 21st Marines, facing only moderate opposition but difficult terrain, cleared Asan Town and gained a foothold on the face of the Fonte Plateau.
On the left flank, Colonel William Hall’s 3rd Marines encountered the heaviest resistance from two complex cave defense systems on Chonito Cliff and Bundschu Ridge. Hall’s men cleared Chonito Cliff and Adelup Point after several costly assaults and heavy casualties, but progress against Bundschu Ridge was limited, resulting in a 200-yard-wide gap between the 3rd and 21st Marines. Nevertheless, General Turnage secured a beachhead approximately 1600 by 4000 yards and had landed all division infantry, artillery, and support units, at the cost of 105 killed, 536 wounded, and 56 missing.
Upon receiving the alert of enemy landings, Takashina promptly mobilized his reserve units to the Fonte Plateau in an attempt to contain Turnage’s Marines within their limited beachhead. Throughout the night, he initiated several fragmented counterattacks, all of which were easily thwarted, resulting in significant Japanese casualties. In the southern sector, the 4th and 22nd Marines heroically fended off numerous well-coordinated counterattacks, managing to destroy four enemy tanks and eliminate Colonel Suenaga along with his 38th Regiment. By July 22, Geiger’s forces began to expand their footholds on the beaches. In the northern front, Hall’s assault on the Bundschu Ridge faced formidable resistance. Despite some Marines reaching the ridge with support from 20mm and 40mm fire, they were compelled to withdraw due to intense mortar shelling. Unbeknownst to them, their relentless attack forced the Japanese to abandon the position, albeit at a significant cost to the 3rd Marines, which suffered up to 615 casualties and was unable to sustain the advance. Meanwhile, Butler’s 21st Marines encountered difficulty clearing the ravine separating them from the 3rd Marines, necessitating the deployment of their reserve 1st Battalion to support the depleted 2nd Battalion. On the right flank, Craig’s 9th Marines encountered minimal resistance as they swiftly secured the Piti Navy Yard, followed by the landing of the 3rd Battalion on Cabras Island after extensive naval and aerial bombardment. The only significant engagement during the night was a Japanese bayonet charge backed by mortar fire, which Butler’s 1st Battalion successfully repelled, inflicting heavy losses on the enemy.
To the south, following the night landings, the 305th Regiment underwent reorganization while Tanzola's 2nd Battalion relieved Shapley’s 2nd Battalion. Schneider’s 22nd Marines encountered moderate resistance as they moved northward after crossing the Ajuya River. Despite lacking tank support, they advanced until halting approximately 250 yards north of RJ 5. Simultaneously, Shapley’s 4th Marines launched an assault towards Mount Alifan's steep slopes, successfully neutralizing entrenched enemy positions using demolitions and grenades, though hindered by rugged terrain. Eventually, a platoon reached the summit, finding no enemy presence. Tanzola’s 1st and 3rd Battalions then advanced along Harmon Road towards the Maanot Pass, navigating eroded hills and dense vegetation to secure the O-a high ground line.
The 306th Infantry Regiment's landing on the White Beaches required the entire day because of communications problems and landing craft shortages. It was not until the next day that the 4th Marines was fully replaced by the 306th. 3rd Amphibious Corps Artillery was landing over White 1 at this same time, as was the 77th Division Artillery, leading to a great deal of congestion, especially when coupled with the landing of smaller units, supplies, and ammunition. Most artillery battalions were in-place by nightfall as was the 9th Defense Battalion deployed along the beaches. The defense battalions, besides providing air defense and direct fire support on ground targets, were positioned to engage any Japanese counter-landing attempts on the beachhead. The 77th Division, with the 305th on the right (center of the beachhead) and the 306th on the left, would secure the southern portion allowing the 4th Marines to move north with the 22nd Marines to seal off the neck of Orote Peninsula.
They continued their advance beyond Harmon Road and Maanot Pass, securing commanding positions overlooking Orote Peninsula. Meanwhile, Schneider’s 22nd Marines, initially advancing rapidly against scattered resistance, encountered intense enfilade fire from hills surrounded by rice paddies while attempting to maneuver across the neck of Orote Peninsula. This compelled them to withdraw approximately 400 yards to a line of hills south of Old Agat Road.
Further to the north, Hall’s 3rd Marines eventually discovered that the Bundschu Ridge had been deserted. However, following their clean-up operations, they were not in a condition to advance any further. Craig’s 3rd Battalion successfully secured Cabras Island and then relieved the 2nd Battalion on the mainland. Meanwhile, Butler’s 21st Marines faced challenges in bridging the gap with the 3rd Marines and encountered limited progress against well-fortified enemy pillboxes on the plateau’s slopes. Turnage initiated the first contact attempt with Shepherd’s brigade on July 24th, but the 30-man patrol was forced to retreat due to enemy fire. Despite Butler’s 2nd Battalion's efforts to close the gap by attacking up the ravine, they were repeatedly hindered by heavy machine-gun fire from caves on the cliff sides. Although both the 3rd and 9th Marines managed to enhance their positions, Turnage's casualties rose to 2034 since the initial landing.
Further south, Shepherd, in response to the formidable defense on the neck of the Orote Peninsula, instructed Schneider to advance the 1st and 3rd Battalions in company columns along the Agat-Sumay Road. The objective was to penetrate the enemy lines and seize the O-2 Line from the coast to Apra Harbor, while the 2nd Battalion shifted to occupy strategic high ground near Atantano from its position on the Old Agat Road. This maneuver not only flanked the Japanese strongholds guarding the rice paddies but also established a barrier across the neck of Orote, securing the beachhead line in front of the brigade.
Following an extensive air, artillery, and naval bombardment, Schneider's primary thrust along the Agat-Sumay Road encountered determined resistance but successfully advanced to the R-2 Line. The 1st Battalion then spread out to the right, while the 3rd Battalion veered further east across the hills, swiftly capturing the fortified positions around the rice paddies that had posed significant challenges the previous day. By nightfall, the 1st Battalion had reached the O-2 Line, but the 3rd Battalion halted 400 yards short of its target, prompting Shapley's 2nd Battalion to fill the breach between them. After repulsing a vigorous counterattack, the 2nd Battalion pushed forward with minimal opposition and secured Atantano. Consequently, by the end of July 24, Shepherd had firmly established his beachhead and contained the enemy on the Orote Peninsula, albeit with casualties totaling 200 killed, 748 wounded, and 97 missing. General Bruce, with the remainder of the 77th Division, assumed control of most of the beachhead perimeter, while Shepherd's Marines readied for the capture of Orote. Subsequently, after repelling several tank-led counterattacks resulting in the destruction of 12 Japanese tanks, they sealed off the peninsula entirely on July 25. By afternoon, approximately 2500 troops under Commander Tamai Asaichi were confined to the eight square miles of Orote Peninsula. Meanwhile, Turnage pressed his forces to secure the objective beachhead definitively.
Accordingly, the 9th Marines progressed southward along the Apra Harbor shoreline towards the Aguada River, reaching the midpoint before being compelled to retreat to the Laguas River due to Craig's stretched lines. Meanwhile, the 21st Marines faced formidable defenses at the Mount Chachao-Aluton-Tenjo complex, managing to establish defensive positions just shy of Mount Tenjo Road after slow progress. Simultaneously, the beleaguered 3rd Marines, with reinforcements from Craig's 2nd Battalion, launched a determined assault, overcoming moderate resistance and mortar fire to seize Mount Tenjo Road and gain a vantage point. Despite the extended frontline, troops stationed on the newly captured high ground could finally survey the terrain ahead by nightfall.
As Takashina consolidated his forces on the plateau, he prepared for a coordinated counterattack aimed at dividing and conquering the enemy. The 48th Independent Mixed Brigade planned to strike Turnage's left flank before pivoting northeast to target Hall's rear. Meanwhile, the 18th Regiment aimed to assault Butler's positions and advance toward the coast to establish a new defensive line, targeting the enemy's headquarters, artillery, and supply units. Additionally, elements of the 10th Independent Mixed Regiment were tasked with exploiting an 800-yard gap between the 9th and 21st Marines, protected only by the 3rd Reconnaissance Company.
In a desperate move following a failed attempt to evacuate by barge, Tamai opted for a nighttime banzai charge with his trapped 2500-strong force, seeking to break free from the Orote Peninsula and join Takashina's troops at Fonte. After dusk, the intermittent showers that had been falling all day became more frequent. A heavy downpour hampered organization of the brigade's defense for the night. On the other hand, the pitch blackness and the unpleasant weather aided the Japanese in making preparations for their supreme effort. Marines in the front lines could hear screaming, yelling, laughter, and the breaking of bottles as the Japanese made final arrangements. At times so much clamor could be heard that reports reached the command post that the assault had started. Afterwards someone aptly said that the confusion "sounded like New Year's Eve in the Zoo." While the enemy made ready and drank, Marine artillerymen laid down normal barrages along the swamp's edge and at all other points of possible penetration. Shortly before midnight the Japanese commanders felt that their men had reached the proper emotional state, and the assault began. Sake-crazed attackers swarmed from the cover of the mangroves in front of the 3rd Battalion, 22nd Marines. Led by flag-waving, sword-swinging officers, the enlisted men stumbled forward, carrying everything conceivable. Unsteady hands clutched pitchforks, sticks, ballbats, and pieces of broken bottles, together with the normal infantry weapons. The assault faced formidable resistance from Marine forces, particularly Shapley’s 1st Battalion, which alone accounted for 256 enemy casualties.
When the surging Japanese mass came within range, Marine forward observers and company commanders gave the order to commence firing. Brigade, 77th Division, and corps artillery, 37mm guns, 81mm and 60mm mortars, machine guns, rifles, and grenades saturated the entire area. At one time officers brought the fire of the Pack Howitzer Battalion, 22d Marines, to within 35 yards of 3/22's front lines in an at tempt to stop the swarming horde. One weapons company lieutenant reported: "Arms and legs flew like snowflakes. Japs ran amuck. They screamed in terror until they died." But in a powerful attack it is inevitable that some men will seep through the blocking fire. Company L, 3/22, received the brunt of the subsiding attack and repulsed it before too much damage could be done. Those Japanese who survived fled to the momentary safety of the swamp. But observers shifted the artillery fire and between midnight and 0200 some 26,000 shells took a heavy toll of the remaining peninsular defenders. On the right flank of the 22d Marines a second counterattack hit. The Island War describes the action quite vividly: “. . . At its height, flares revealed an out-of-this-world picture of Nipponese drunks reeling about in our forward positions, falling into foxholes, tossing aimless grenades here and there, yelling such English phrases as they had managed to pick up, and laughing crazily, to be exterminated in savage close-in fighting. Succeeding waves were caught in a deadly cross-fire. Not until dawn did this attack finally dwindle out, at which time more than four hundred bodies were counted in front of the position.” In contrast to the frenzied close quarter action in the 3/22 zone, the platoon from Company A (1/4) that filled the gap between the two regiments participated in a shooting gallery affair with the Japanese. Enemy troops made no attempt at a concerted attack, and the platoon plus artillery, without the loss of a single Marine, killed 256 Imperial soldiers. This fantastic figure was verified by officers from regiment the following morning.
Despite the intense machine-gun and artillery fire, some Japanese managed to infiltrate Marine positions, engaging in fierce hand-to-hand combat. However, by dawn, the Japanese offensive had been halted, with most remaining enemy forces eliminated, leaving Tamai with no option but to defend Orote Peninsula to the end. Meanwhile, Takashina's main assault, launched on July 26 at 04:00, faced initial success in overrunning Company B positions but was ultimately contained by the relentless machine-gun fire of the 1st Battalion.
Major Maruyama's men (2/18) advanced noisily, shouting, "Wake up American and die." The initial impetus of the assault passed completely over Company B in the center, previously reduced to about 50 men, and streamed through the gap down a draw toward the cliff. Despite the breakthrough, companies held the shoulders of the penetration and Lieutenant Colonel Williams ordered the units to refuse their flanks to the cliff. Company A on the left, commanded by Captain William G. Shoemaker, rallied in the face of the withering fire and overwhelming numbers. Shoemaker pulled back his right platoon to deny his flank to the enemy and to permit regrouping for a local counterattack. Company C (Captain Henry M. Helgren, Jr.) also successfully refused its flank to protect the position and immediately began firing into the onrushing Japanese. Tanks parked in the rear of the Marine positions took a great toll as the intruders surged through the widening gap. One report described the rush on the tanks as resembling a horde of ants. It went on to say of the Nipponese: “Savagely they swarmed upon the mechanized vehicles, oblivious of the vicious machine-gun fire, and frantically pounded, kicked, and beat against the turrets in an attempt to get the crew within. When this seemed futile they leaped to the ground and continued their wild rush down the draw to the rear areas. . .” Demolition charges were forgotten in the mad scramble to reach deeper into Marine-held territory. Machine gunners of 1/21 had a field day. Never had they seen such lucrative targets, but grenades and bayonets soon silenced the Marines as enemy soldiers overran the gun positions. Many of the Japanese were killed as they moved through the lines and into the ravine.
Although some of the infiltrating Japanese got down the cliff to attack the battalion command post and Butler’s mortar platoons, killing most of the mortarmen before being repelled by service troops, To the left, Craig’s tenacious 2nd Battalion, in its exposed position, received the brunt of Shigematsu’s attack, yet it managed to defeat seven determined counterattacks without losing any ground. Nonetheless, though they killed 950 Japanese, they suffered 50% casualties as well. Looking right, Ohashi’s 3rd Battalion hit Butler’s 3rd; and although two machine-guns were initially captured, their attack ended up being rapidly repelled. Consequently, the Japanese slid along the front and attacked down the vulnerable 800-yard gap, successfully defeating a strong roadblock to set up a dangerous line on the high ground behind Butler’s 3rd Battalion.
The lack of a swiftly organized regimental reserve line led to approximately 70 Japanese infiltrating into the Division Hospital area, where they were eventually repelled by a pioneer force. The first warning came about 6:30 when corpsmen reported that a number of enemy soldiers could be seen on the high ground to the right of the hospital. Division headquarters immediately ordered Lieutenant Colonel George O. Van Orden (Division Infantry Training Officer) to take command of two companies of pioneers standing by for just such an eventuality and clear the enemy from the hard-pressed area. At the hospital, doctors ordered patients to evacuate the tents and go to the beach. Onlookers saw a pathetic sight as half-clothed, bandaged men hobbled down the coast road helping the more seriously wounded to safety. 41 of the patients grabbed rifles, carbines, hand grenades, and whatever else they could find and joined the battle. The hospital doctors, corpsmen, and pajama-clad patients presented a rare sight as they formed a defensive line around the tents. It was a solid line, however, and one that held until the recently organized reinforcements arrived. Only one patient was wounded during the fighting, but one medical officer and one corpsman later died of wounds. The casualty list also included one medical officer, one dental officer, one Navy warrant officer, 12 corpsmen, and 16 Marines from the medical companies wounded in action. This does not include those casualties suffered by Van Orden's force. After cleaning out the assigned area, Van Orden proceeded up the Nidual River Valley in pursuit of the fleeing Japanese. The attack had pushed the enemy back to the hill at the head of the ravine by 11:00, but a request to send a Marine patrol to the ridge to determine the hostile strength was denied. Other plans had already been made for the assault of this dominating terrain. It was from this high ground that Major Yukioka's men paralyzed the operation of 3/21's CP and threatened the flank of both the 9th and 21st Marines.
While this action was taking place, the 12th Marines CP and several of its battalions were engaged in stopping the suicide squad attacks. In order to have these parties in position to make their foray in conjunction with the all-out offensive, enemy commanders had ordered the groups to infiltrate behind Marine lines on the night of 24-25 July. With typical Japanese patience, the raiders lay hidden in caves all day. As soon as darkness came on the night of 25-26 July they started firing random shots into the headquarters of the 12th Marines and began to move in small groups down the Asan Valley. A hand grenade duel went on during the early hours of darkness, but some of the intruders sought the safer confines of a cave not 20 feet from the headquarter's fire direction center. The artillerymen's perimeter defense held, and only one of the enemy succeeded in getting through to the guns. He was killed in the 3d Battalion's area before he could do any damage. In the five-hour long fighting around the regimental headquarters, 17 explosive-laden Japanese died. Most of them carried packs containing about 20 pounds of TNT with ready detonators, while others carried magnetic mines. With the coming of daylight, patrols went out to clean up any troops that might cause trouble later in the day. Men of the 12th Marines killed approximately 50-60 more enemy soldiers and drove the remainder into other areas where they were liquidated one by one.
Despite the initial success of Takashina’s well-coordinated counterattack, by noon, his forces had suffered defeat, marking the breaking of the backbone of Japanese resistance on Guam. Marine casualties were significant, with around 166 killed, 645 wounded, and 34 missing between July 25 and 27. Consequently, the 9th Marines retreated approximately 1500 yards to establish better defensive positions, and a battalion of Colonel Stephen Hamilton’s 307th Regiment was deployed near Piti Navy Yard. However, the focus now shifted to covering the invasion of Tinian. While naval guns had intermittently harassed Tinian since June 11, the preliminary bombardment of Saipan’s sister island commenced on June 20, with the first Army artillery battery targeting northern Tinian. By July 9, the 531st Field Artillery Battalion had fired a total of 7571 rounds. Following the fall of Saipan, the remaining 24th Corps Artillery and Marine howitzers intensified the bombardment, maintaining a continuous round-the-clock schedule and expending a total of 24,536 rounds on northern Tinian.
For the most part, 14th Corps Artillery confined its efforts to the area north of the line between Gurguan Point and Masalog Point, while aircraft restricted their efforts to the southern half of the island. Naval ships were assigned any targets on Tinian deemed unsuitable to either of the other two arms. Coordination of the three supporting arms was assigned to the corps artillery representative attached to General Schmidt's staff. In one instance, an artillery air observer discovered three 140-mm. coastal defense guns on Masalog Point that were within easy firing range of White Beaches 1 and 2, but were masked from field artillery. The battleship Colorado was called in and, with its main batteries adjusted by an airborne artillery observer, succeeded in neutralizing or destroying the enemy weapons. Because the spotting plane was not in direct radio contact with the ship, it was necessary for the plane to submit its spotting data to the artillery post by radio, whence they were relayed by telephone to General Schmidt's headquarters, and in turn by radio on another frequency to the firing ship. In spite of this somewhat complicated system of communications, the time lag was so slight as to be insignificant.
Meanwhile, starting from June 22, the P-47s belonging to the 318th Fighter Group maintained a relentless barrage on the airfields at Ushi, Gurguan Point, and just east of Tinian Town through constant strafing and bombing, further devastating the town to ruins. Beginning on July 15, naval gunfire operations were reinstated, with Admiral Hill’s cruisers and destroyers delivering destructive bombardment daily against Tinian’s harbor defenses. Then, on July 22, two P-47s dropped the first napalm bombs used in the Pacific war on Tinian, proving highly effective in incinerating canefields, underbrush, and enemy personnel located in open trenches and dugouts. The following day, Hill intensified preparatory fire with a formidable naval force comprising three battleships, two heavy cruisers, three light cruisers, and sixteen destroyers, positioned strategically to shell Tinian from all directions. However, there was no attempt to focus on the White Beaches to mislead the Japanese about the actual landing point. Throughout the rainy night, destroyers and cruisers maintained control over crucial road junctions while an UDT conducted a last-minute underwater reconnaissance, albeit unsuccessfully attempting to detonate recently discovered mines due to adverse weather conditions. At dawn on July 24, Hill’s transports carrying the 2nd and 4th Marine Divisions finally departed from Tanapag Harbor for the short journey to Tinian, successfully reaching their designated areas by 06:00. Simultaneously, the onslaught of artillery, air raids, and naval bombardment persisted over the Japanese defenses, intensifying into a full-scale onslaught by 07:00, with particular focus on the White Beaches. Additionally, efforts were made to neutralize mines on White 2, although these attempts proved futile.
As the assault waves took shape, General Watson’s Marines effectively executed the demonstration near Tinian Town without suffering any casualties. This demonstration effectively held the defenders in place, preventing them from deploying northward. However, a cleverly concealed Japanese battery managed to inflict significant damage on the battleship Colorado and the destroyer Norman Scott, resulting in the loss of 62 lives and 245 wounded before being neutralized. At 07:17, the initial landing wave crossed the designated line and began the 3000-yard journey to the beach, supported by intense pre-landing bombardment and rocket fire from LCI gunboats.
At about the same moment small-caliber fire--estimated variously as 50-caliber, 20mm and 40mm--began falling around the LST's. Its source could not be located because of the pall of smoke and dust that cloaked the island. Regarding this incident the logistics officer of the 2d Battalion, 23d Marines, aboard one of the LST's in the area, recalled: “The fire . . . wounded two or more Navy enlisted men of the crew of the vessel, and possibly a couple of Marines belonging to the landing team. . . . My recollection concerning the Marines who were wounded is hazy . . . the incident created a stir and speculation concerning the source of the fire, but everyone soon settled down to the business at hand.” Despite encountering the sporadic small-caliber fire, the LVTs successfully reached the narrow beaches by 07:50. Upon landing, Company E of the 24th Marines swiftly engaged and eliminated a small beach-defense unit on White 1, while the remainder of the battalion made landfall. On White 2, the 2nd and 3rd Battalions of the 25th Marines landed simultaneously but faced a delay in advancing due to the need for engineers to clear 100 horned mines that had destroyed three LVTs. Subsequently, Colonel Batchelder’s Companies G and I circumvented two enemy blockhouses and initiated an inland attack, while other units subdued strongpoints. However, the presence of additional mines and staunch resistance from caves and ravines prevented them from reaching their objective at the O-1 Line and Mount Maga. Meanwhile, Colonel Hart’s 1st and 2nd Battalions of the 24th Marines successfully advanced to the O-1 Line amid minimal opposition. Later in the day, reserve and artillery battalions were landed, along with Colonel Jones’ 23rd Marines, although their landing was delayed due to communication issues. This delay proved beneficial due to heavy congestion on White 2 at the time.
By nightfall, Colonel Wallace’s 1st Battalion, along with the 2nd and 4th Tank Battalions, under Hill's command, successfully disembarked 15614 men ashore. General Cates, anticipating Japanese counterattacks, directed his troops to halt at 16:30 to fortify defenses, achieving a beachhead spanning about 7000 yards. This came at a cost of 15 Marines killed and 225 wounded. Ogata, as expected by Cates, immediately ordered counterattacks with the 1st and 2nd Battalions of the 50th Regiment and mobilized the Mobile Counterattack Force. While Japanese probes commenced at 22:30, the major assaults, marked by fierce banzai charges, began after midnight.
The attack on the left came first and lasted longest. At 2:00, men of the 1st Battalion, 24th Marines, straining their eyes through the black moonless night, suddenly saw a compact group of Japanese a short 100 yards away. The Marines opened fire. The compact group became a screaming mass of attackers as the first Marine bullets and shells found targets. Now the shadows were alive with about 600 leaping Japanese naval troops, loaded with aggressive spirit, requiring no instructions to make their screaming charge. Marines called flares into action; the battlefield became light. Marines needed no orders either: the 37mm guns sprayed canister; machine guns cut into the enemy area with grazing fire; rifles pounded out at sighted or suspected targets; mortars crunched into the defilade areas; artillery crashed steadily behind the Japanese to shatter and destroy any reinforcement group. The tightly packed foe was a choice target for all these weapons, and hundreds of shells lashed his ranks. At no time did the enemy penetrate the 1st Battalion; but extremely heavy pressure against Company A, the unit that bore the brunt, caused the battalion commander to reinforce it with engineers, corpsmen, communicators, naval gunfire liaison and shore party personnel. The fight continued hot and heavy until about 0545, when dawn and the vigor of the enemy effort broke simultaneously. Medium tanks from Company B, 4th Tank Battalion, entered the fray at this time and stopped all further thrusts at the Marines' lines. Many Japanese, convinced that all was lost, committed suicide with grenades. While armored amphibians afloat fired on enemy groups hiding along the coast, Marines of the 1st Battalion, 24th Marines, mopped up the area to their front, an activity completed by 0700. They counted 476 Japanese bodies, most of them within 100 yards of Company A's lines. Although no figures are available for Marine casualties in this action, the battalion commander estimated that ". . . Company A was reduced to about 30 men with usable weapons before the enemy was repulsed."
Ogata’s infantrymen struck Cates’ center thirty minutes later, yet their efforts were thwarted by intense small-arms, mortar, and 37mm fire. Despite briefly breaching the line through weak points, they were ultimately defeated by rear elements after prolonged and heavy fighting.
This time, though many of the attackers fell forward of the lines, others penetrated a weak spot at the boundary between the two Marine regiments. About 200 Japanese poured through this spot before the flow could be stopped. After pausing in a swamp behind the lines, the enemy force speared out in two prongs: one straight into the beachhead toward U. S. artillery positions, the other turning west into the 25th Marines' rear areas. The latter group of Japanese attained first contact when they met a well-prepared support platoon from the 3d Battalion, 25th Marines. Positioned to contain just such a penetration as had occurred, the Marines quickly eliminated this Japanese threat, killing 91 in a brief, violent skirmish. The other prong pushed deep into the rear of the beachhead, finally reached the 75mm howitzer firing positions of the 2d Battalion, 14th Marines. Battery D, firing a mission for the 24th Marines, suddenly found itself beset from the front by many determined Japanese. Marines not actively engaged in servicing the howitzers rallied to the defense of their positions with small arms, while the remainder continued firing an artillery mission for the 24th Regiment. Later, as pressure mounted, all hands turned to the task of stopping the Japanese close at hand. At this juncture the .50-caliber machine guns of the other two batteries (E and F) of the battalion levelled a heavy volume of enfilading fire into the area forward of besieged Battery D. This fire, in the words of the battalion executive officer, "literally tore the Japanese . . . to pieces." To reinforce Battery D in its bitter fight, Company C, 8th Marines, arrived at 0445. But by then the situation was well in hand; the Japanese had faltered and stopped before the deluge of small-arms fire. Morning revealed about 100 dead Japanese in the area, while the artillerymen had lost but two of their number--both killed manning a .50-caliber machine gun with Battery D. The only Japanese penetration of the night had shattered itself against a prepared rear area. Up at the front, meanwhile, Marines of the 25th Regiment and the right (2d) battalion of the 24th Regiment, fought off a series of frontal rushes upon their positions. In each case the Japanese were stopped at the barbed wire forward of the Marines' lines. The all-night firing had taken a heavy toll of the Marines' ammunition stocks, however, and by shortly before daylight there was concern along the lines that another heavy attack might exhaust supplies. Dawn came first. Attached tanks moved up at once to range the area forward of the lines. They blasted points of resistance with their 75mm guns, killing or chasing such few Japanese as had survived the night melee. Nearly 500 Japanese were killed in the attacks against the center of the beachhead and in the skirmishes behind the lines following the penetration.
The third and last major enemy effort struck the extreme right (south) flank of the beachhead at 3:30. The 2d Battalion, 23d Marines, in position along the coast, bore the brunt of this thrust, although the 2d Battalion, 25th Marines, also figured prominently in the action. Moving north along the coastal road, the enemy force consisted of five or six light tanks (about half of those available to the Japanese at Tinian) with infantrymen riding and following on foot. First warning of the enemy move came when Marine listening posts stationed along the road a short distance forward of the lines reported enemy tanks rumbling in from the south. With the tanks an estimated 400 yards in front of the lines, Marine artillery opened up. The tanks came on. Ready for just this situation, U. S. ships began firing illuminating shells over the area, virtually turning night into day. Bazookas, 75mm half-tracks, and 37mm guns attached to three battalions now went into action. One of the 37mm platoons, positioned astride the coral road, leveled point-blank fires into the enemy armor. Even so, one fast-moving tank weathered a 37mm hit and drove through the front lines into rear areas before a Marine bazookaman finished it off. An officer present on the scene described the action as he saw it: “The three lead tanks broke through our wall of fire. One began to glow blood-red, turned crazily on its tracks, and careened into a ditch. A second, mortally wounded, turned its machine guns on its tormentors, firing into the ditches in a last desperate effort to fight its way free. One hundred yards more and it stopped dead in its tracks. The third tried frantically to turn and then retreat, but our men closed in, literally blasting it apart. . . . Bazookas knocked out the fourth tank with a direct hit which killed the driver. The rest of the crew piled out of the turret, screaming. The fifth tank, completely surrounded, attempted to flee. Bazookas made short work of it. Another hit set it afire, and its crew was cremated.” Thus, five tanks stood immobile on the field of battle. If a sixth accompanied this incursion, it escaped, since there was no trace of it the following morning when Marines moved through the area. Despite the fact that their armor was gone, enemy foot soldiers from the 1st and 2d Battalions, 50th Infantry, and the 1st Battalion, 135th Infantry, pressed toward the Marines. The fighting that ensued was close-in and savage, but the Japanese never cracked the tight defense. The few who seeped through the lines met a quick end at the hands of the 23d Marines' reserve (1st Battalion), positioned to provide depth in this precise area. The operations officer of the 2d Battalion, 23d Marines, described the weird termination of the Japanese activities: “. . . as it began to get light, Jap bodies began to fly ten to fifteen feet in the air in the area in front of our lines. . . . We knew that hand grenades did not have the power to blow a man's body that high and could not figure out what was happening. [Later] we moved out to mop up. . . . It turned out that about fifty percent of the dead Japs carried magnetic mines and had obviously been ordered to break through our lines and destroy the tanks in the rear of us. . . . The Japs who were wounded and unable to flee were placing the tank mines under their bodies and tapping the detonators.” Daylight revealed that the enemy had expended 267 men and five tanks (of 12 on the island) against the right flank of the beachhead with no success. By the end of the night's counterattacks, 1241 Japanese bodies lay scattered along Cates’ front, with the 1st Battalion, 135th Regiment virtually decimated, while Marine casualties numbered less than 100. Reflecting on the engagement, they later concluded: "It was there and then that [we] broke the Jap's back in the battle for Tinian". This assessment proved accurate, as Ogata’s forces began retreating towards the southern end of the island.

Similar to the experience invading Saipan, Guam and Tinian proved to be literal horror shows. The savagery of the Island hoping campaign had increased ten-fold. The Japanese hoped by inflicted as much pain as possible, the Americans might simply come to the peace table, but was there any real chance of that?

- 139 - Pacific War -First Bombing Campaign against Japan, July 16-23,1944
16 7月· The Pacific War - week by week
Last time we spoke about battle of Noemfoor. General MacArthur initiated a successful offensive on Noemfoor, with General Patrick's troops securing a beachhead. American forces encountered minimal resistance, occupying key positions. Despite initial skirmishes, American defenses held firm, inflicting heavy casualties. Meanwhile, in Aitape, ongoing clashes saw American forces repelling Japanese assaults. Despite setbacks, American defenses held, and preparations for a counteroffensive were underway. The Japanese breached American lines, occupying a 1300-yard gap but faced intense resistance. Martin ordered counterattacks and reorganization of forces along the X-ray River-Koronal Creek line. Despite some delays, American forces repelled Japanese assaults. In the Battle of Imphal, British-Indian troops repelled Japanese attacks, leading to their retreat. Operation Crimson saw successful naval and air assaults on Japanese positions, though with some setbacks. Admiral Somerville's diplomatic transfer followed, amidst reorganization of SEAC's higher officers due to internal conflicts.
This episode is the First Bombing Campaign against Japan

Our week's story first takes us over to the China Theater. Last time we spoke about China, the 11th Army's progress was halted at Hengyang in early July due to the resilient defense led by General Fang and a severe shortage of ammunition. General Yokoyama had to pause the offensive until his artillery unit could arrive to bolster the siege. Meanwhile, the 64th Division was dispatched to Changsha to relieve garrison duties. Despite these setbacks, the 13th Division secured Leiyang by July 4, and the 40th Division took control of Yongfeng on the same day, followed by Zhajiang on July 6. Although Hengyang was nearly surrounded, the Japanese forces had to entrench due to lack of supplies, which were delayed and harassed by General Chennault’s aircraft. Seizing this opportunity, General Xue Yue sent reinforcements and launched counterattacks against the besiegers. The 58th Army recaptured Liling on July 8 before being pushed back by the 27th Division two days later, while the Chinese forces began encircling Maoshizhen from the southwest by mid-July. By July 10, Yokoyama had received sufficient artillery and ammunition to resume the attack on Hengyang. Despite heavy air and artillery support, the 116th Division's assaults from the southwest failed to breach Fang’s defenses once again.
On July 15, the Japanese launched another assault, this time managing to displace the exhausted defenders from their outer positions and into the city itself. Two days later, the 13th Division also gained control of the airfield on the east bank of Hengyang and strategic points along the railway near the town. Despite these territorial gains, they were deemed insufficient considering the significant loss of life endured during the intense fighting of that week. Consequently, Yokoyama decided to pause the offensive once more on July 20, intending to concentrate his forces around Hengyang. The 40th and 58th Divisions were already en route to reinforce the front lines. However, during this period, two significant aerial operations occurred. Initially, following the bombing of Yawata, General Arnold ordered a subsequent night raid on Japan to underscore that Operation Matterhorn marked the beginning of a sustained bombing campaign, distinct from the isolated nature of the Doolittle raid. This was followed by a 100-plane attack on Manchuria and a 50-plane attack on Palembang.
Two days after the Yawata show General Arnold informed Wolfe that, despite the depleted fuel stocks in China, it was “essential” to increase pressure against Japan. Immediate objectives were: a major daylight attack on Anshan, small harassing raids against the home islands, and a strike against Palembang from Ceylon. When Arnold asked for an estimate of the command’s capabilities, Wolfe’s reply was none too hopeful. With low storage tanks at Chengdu (only 5000 gallons) he could not with his own resources build up for an all-out mission to Anshan before August 10. Ceylon fields would not be ready before July 15, and either the Palembang mission or the night raids would delay the Anshan attack. In spite of Wolfe’s cautious estimate, Arnold on June 27 issued a new target directive calling for a 15-plane night raid over Japan by July 10, a minimum of 100 planes against Anshan between by July 30, and a 50-plane mission to Palembang as soon as Ceylon airfields were ready. To meet this schedule, Wolfe was admonished to improve radically the operations of C-46s and B-29s on the Hump run. He outlined conditions necessary for fulfilling the directive: build-up of his B-29 force and a flat guarantee of ATC Hump tonnage. Even when it was decided that the command would get back its 1500 tons for July, Wolfe’s operational plan set up the Anshan mission for 50 to 60 B-29s, not 100 as Arnold wanted. Arnold received this plan on July 1. On the 4th General Wolfe was ordered to proceed immediately to Washington to take over an “important command assignment” and two days later he departed. Thus General Wolfe was in reality sacked, leaving General Saunders to assume temporary leadership.
Subsequently, on July 7, the requested night raid was carried out, involving 18 B-29s targeting the Sasebo Naval Base, with an additional six attacking other sites in Nagasaki, Omura, Yawata, and Tobata. Of the 24 bombers, 11 successfully bombed Sasebo using radar; individual planes struck Omura and Tobata, while the B-29 assigned to Yawata inadvertently bombed the secondary target at Laoyao harbor. Two other bombers, experiencing fuel-transfer issues, redirected to bomb Hankow, narrowly missing it by 20 miles. Despite witnessing explosions in all targeted areas, the damage inflicted on Japanese infrastructure was minimal. Only one bomber sustained damage, yet the successful attack heightened panic within the Home Islands.
After the disastrous loss of Saipan, it was clear to many of Japan's elite that the war was all but lost. Now Japan needed to make peace before the kokutai and perhaps even the Chrysanthemum Throne itself was destroyed. Tojo had been thoroughly demonized by the United States during the war, thus for the American people, Tojo was clearly the face of Japanese militarism. It was thus inconceivable that the United States would make peace with a government headed by Tojo. British historian H. P. Willmott noted that a major problem for the "doves" was that: "Tojo was an embodiment of 'mainstream opinion' within the nation, the armed services and particularly the Army. Tojo had powerful support, and by Japanese standards, he was not extreme." Tojo was more of a follower than a leader, and he represented the mainstream opinion of the Army. This meant his removal from office would not end the political ambitions of the Army who were still fanatically committed to victory or death. The jushin, elder statesmen, had advised Emperor Hirohito that Tojo needed to be sacked after Saipan and further advised against partial changes in the cabinet, demanding that the entire Tojo cabinet resign. Tojo, well aware of the efforts to bring him down, sought the public approval of the Emperor Hirohito, which was denied. Hirohito sent him a message to the effect that the man responsible for the disaster of Saipan was not worthy of his approval. Tojo then suggested reorganizing his cabinet to retain his position, but was rebuffed again. Hirohito said the entire cabinet simply had to go. Once it became clear that Tojo no longer held the support of the Emperor, his enemies had little trouble bringing down his government.The politically powerful Lord Privy Seal, Marquis Kōichi Kido spread the word that the Emperor no longer supported Tojo. Thus after the fall of Saipan, he was forced to resign on July 18, 1944.
Admiral Yonai Mitsumasa and General Koiso Kuniaki were appointed by Hirohito to form a new government, with Koiso ultimately becoming Prime Minister as Tojo's replacement. Meanwhile, Lieutenant-General Shimoyama Takuma’s 5th Air Army discovered Chennault’s aircraft and two Chinese squadrons concentrated at Guilin airfield on July 13. Seizing this opportunity, Shimoyama launched a daring raid that caught the Allies off guard, resulting in 80 aircraft destroyed on the ground. Despite this initial setback, Chennault’s P-51 Mustangs maintained superiority over the Zero, downing 88 Japanese aircraft in the following weeks at the cost of 27 Allied planes.
In Hengyang, preliminary artillery bombardment commenced on July 27 as Yokoyama’s forces prepared for their final offensive. Despite minor attacks in the subsequent days, little progress was made while the Japanese awaited the arrival of the 58th Division. Concurrently, the 27th and 34th Divisions advanced towards Lianhua to eliminate the 58th Army, resulting in heavy casualties and their subsequent withdrawal. By August 1, Yokoyama had amassed 110,000 troops around Hengyang, along with heavy artillery and mountain artillery pieces. In contrast, only 3,000 exhausted Chinese troops remained, valiantly resisting despite being cut off for over a month.
Returning to Matterhorn, Arnold insisted on a meticulously planned daylight attack involving 100 planes to be executed in July. Saunders managed to fit in the Anshan strike at the month's end by delaying Palembang until mid-August. The primary target was the Showa Steel Works at Anshan in Manchuria–specifically, the company’s Anshan Coke Plant, producing annually 3793000 metric tons of metallurgical coke, approximately ⅓ of the Empire’s total. About half of this was used by Showa’s own steel works, second in size only to Imperial’s, and the rest for various industrial purposes in Manchuria, Korea, and Japan. The secondary target was Qinhuangdao harbor whence coking coal from the great Kailan mines was exported to Japan. Tertiary target was the Taku port near Tianjin, which handled coal, iron ore, and pig iron. And as a last resort, bombers were to hit the railroad yards at Zhengxian, a possible bottleneck along a Japanese supply route. Aiming point at Anshan, as at Yawata, was to be a battery of coke ovens and again the bomb load was set at eight soo-pound GPs per plane.
Consequently, on July 25, 111 B-29s began staging to China, with 106 successfully arriving four days later. However, on July 29, only 72 B-29s managed to take off for the Anshan strike due to rain muddying the runway at Guanghan, preventing the 444th Group from launching. Mechanical issues further hindered eleven bombers from reaching Anshan, resulting in one bombing Qinhuangdao, two targeting Zhengxian, and four hitting other targets of opportunity. Despite these challenges, the sixty B-29s that reached Anshan maintained formation and bombed from altitudes close to the designated 25,000 feet under clear skies. However, the first wave mistakenly bombed a by-products plant adjacent to the aiming point, enveloping it in thick smoke. Anti-aircraft opposition was relatively light, with heavy flak damaging five B-29s and Japanese fighters downing only one bomber, whose crew escaped with the help of Chinese guerrillas. B-29 gunners claimed three probable hits and four damaged Japanese fighters. Chinese forces aided in rescuing a stranded bomber near Ankang. The plane was on the ground for five days while an engine, spare parts, tools, and mechanics came in by C-46 from Hsinching to effect an engine change and other repairs. Air cover was furnished by 14th Air Force fighters, who shot down a Lily bomber during a night attack. With full assistance from the Chinese and American garrisons at Ankang, the B-29 took off on August 3 and returned to Chiung-Lai. Another B-29 crash-landed in Vladivostok. Fortunately, on July 30, the wet strip at Kwanghan had dried sufficiently to launch 24 bombers of the 444th, albeit nearly five hours behind schedule. However, they were too late for Anshan, with 16 bombing the Taku port and three targeting Zhengxian instead. The day's efforts, though not flawlessly executed, brought encouragement to the command. American reconnaissance reported significant damage at Anshan, including hits and near misses on several coke-oven batteries, related installations, and the by-products plant. Taku and Zhengxian also showed substantial damage. The command gained valuable insights into conducting daylight missions, and despite the loss of five B-29s, it was deemed acceptable. That is all for now for the China theater as we now need to jump over to Burma.
Meanwhile, in north Burma, General Wessels decided to resume the offensive on July 12. Following a heavy air and artillery bombardment, a coordinated attack was launched, supported by 39 B-25s and the 88th Fighter Squadron, which successfully dropped 754 tons of bombs on Myitkyina. However, approximately 40% of the bombs landed among American troops north of Sitapur, resulting in casualties and confusion. Consequently, the coordinated attack stalled, with minimal gains by the 88th and 89th Regiments. Subsequently, Wessels' forces reverted to patient day-by-day advances, pushing back Japanese forces gradually. The tightening grip around Myitkyina was evident, with previously separated units now in close contact, preventing Japanese movement. Further south, General Stilwell directed the weary Chindit brigades to converge on Sahmaw and eliminate the 18th and 53rd Divisions. West African troops fought for control of Hill 60 to the north, while the depleted 111th Brigade engaged in battles at Taungni and the heavily fortified Point 2171. Stilwell also ordered the 300-man 77th Brigade towards Myitkyina, but Brigadier Calvert opted to cut off radio communications and withdraw his men to Kamaing, eventually evacuating them to India.
After returning back to Allied lines, Calvert and Lentaigne drove to Stilwell’s headquarters, where they found the general at a table with his son and Boatner. Then, speaking with the same sort of blunt honesty that Stilwell prided himself on, Calvert went into a long monologue explaining that despite their crippling losses and lack of heavy weapons, his men had sacrificed so much at Mogaung that now they had nothing left to give. To order the survivors into combat now was to pass nothing more than a death sentence. Stilwell seemed stunned at Calvert’s contained monologue. Then his shock turned to scathing anger towards his own staff. “Why wasn’t I told?’ he demanded. It quickly became obvious to Calvert that Stilwell had not realized the true tribulations his Chindits had gone through since the gliderborne invasion some months ago. As Calvert later wrote: “It became obvious from Stilwell’s repeated ‘Why wasn’t I told? Is this true?’ that his sycophantic staff had kept the true nature of the battle from him.” Overcome with the truth of it all, Stilwell apologized. “You and your boys have done a great job, I congratulate you.” Calvert was then allowed to evacuate his brigade. Their campaign was finally over.
The other brigades, nearing the edge of their endurance, didn’t experience the same fortune and had to persist in battling against the determined Japanese defenders. With morale faltering, Major Masters' only opportunity for success came through a bold flank attack on July 9 led by Company C of the 3/9th Gurkhas. As the Gurkhas fell back in disarray, savaged by machine-guns firing straight down the ridge, the surviving men scattered, diving into the jungle. Major Gerald Blaker moved on alone, firing his M1 carbine, yelling: “Come on, C Company!” Seeing him, the Japanese threw grenades. Braving the blasts despite an arm savaged by shrapnel, he charged the Japanese. At the last moment, the enemy gunners found the range and a volley of seven bullets plunged into Blaker who fell against a tree, bleeding profusely. He turned his head to call on his men: “Come on, C Company, I’m going to die. Take the position.” The Gurkhas surged forward, bayonets glinting in the dull light, crying: “Ayo Gurkhali, the Gurkhas have come!” Point 2171 then fell into Allied hands. 50 Japanese dead were counted on the summit. Major Gerald Blaker sacrificed his life during the assault and earned a posthumous Victoria Cross.
Shortly thereafter, the 14th Brigade relieved the exhausted 111th, which now counted only 119 fit men; and on July 17, Stilwell finally authorized the evacuation of Masters’ men. Thankfully, the seasoned 36th Division under Major-General Francis Festing would arrive in the frontline area to replace the depleted Chindits by the end of July, enabling General Lentaigne’s remaining forces to be brought back to India. The final to depart were the West Africans, who assisted the British in capturing Hill 60 on August 5, prompting the Japanese to withdraw towards Pinbow and Mawhun. Since the inception of Operation Thursday, the Chindits had suffered 5000 casualties, including killed, wounded, or missing, 3800 of them after Wingate’s demise. Their unconventional warfare had effectively diverted numerous potential reinforcements away from Imphal and Myitkyina; severed the 18th Division’s supply line, rendering its holding operation futile; and highlighted the importance of air supply as the sole means of sustenance during military campaigns, a lesson pivotal in the 14th Army’s subsequent offensives. Shifting focus to Yunnan, by the beginning of July, General Wei’s Y Force had successfully halted General Matsuyama’s counteroffensive in the Longling region.
In the interim, General Kawabe's Burma Area Army was formulating strategies to address the impending aftermath of Operation U-Go's unfavorable results. Following the completion of the 15th Army's retreat in central Burma, plans were set in motion for Operation Ban, a defensive maneuver aimed at countering anticipated Allied advancements along the Irrawaddy River. Concurrently, General Sakurai's 28th Army was organizing Operation Kan in anticipation of potential Allied incursions along the Bay of Bengal coastline. Additionally, General Honda's 33rd Army initiated preparations for Operation Dan, a synchronized offensive designed to repel the invading Chinese forces eastward across the Nujiang River and deep into Yunnan, thus thwarting the establishment of a land route between India and China by the Allies. Consequently, the 2nd Division under Lieutenant-General Okazaki Seisaburo was reassigned to the 33rd Army on July 19 to partake in the offensive, while Matsuyama's 56th Division was tasked with maintaining defensive positions in Yunnan. The 18th and 53rd Divisions were directed to safeguard the western flank against potential assaults originating from Myitkyina. Subsequently, Matsuyama opted to relocate his primary force from Longling to Mangshi, where he planned to rendezvous with Okazaki at a later date. To facilitate this relocation, Colonel Matsui's task force was dispatched on July 5 to dislodge the 76th Division from Mukang. Following a stealthy infiltration behind enemy lines on July 7, Matsui launched a surprise attack the following day, compelling the Chinese forces to retreat. With the route to Mangshi cleared, the 56th Division vacated Longling and began regrouping in the Mangshi vicinity, leaving a modest garrison of 2500 men to secure Longling. Throughout July, the city faced intense aerial and artillery bombardments, culminating in the capture of East Hill by the 87th Division on July 17.
Fortunately, Y Force's efforts were now focused on the previously bypassed blocks at Tengchong, Lameng, and Pingda, as the Chinese prioritized securing the flow of supplies to the front lines. At Tengchong, Colonel Kurashige was compelled to abandon Feifeng Hill after his 3rd Battalion departed to join Matsui’s task force, leaving him with just 2025 men. Facing him, Lieutenant-General Huo Kuizhang’s five divisions spread out around Tengchong, occupying the surrounding heights. Despite attempts at medium-level bombing causing severe damage to the residential area, it only resulted in rubble piling around Japanese positions. Thus, entrenched in their dugouts, the Japanese remained steadfast and successfully repelled Chinese attacks, with the Chinese managing to take Kaoliang Hill only by July 9th. Meanwhile, from the south, the 2nd Reserve Division severed Tengchong from Longling and initiated unsuccessful assaults against Laifeng Hill. By mid-July, with the city completely encircled, Huo was poised to launch a coordinated assault, but heavy rains delayed the operation. Concurrently, with the arrival of the 8th Army at Lameng, General Song aimed to continue his attacks against Major Kanemitsu’s garrison. Following a night-long artillery bombardment, the 1st and 39th Divisions fiercely assaulted Japanese positions on July 5th, successfully overrunning some of them and destroying Kanemitsu’s main water reservoir. However, despite ammunition shortages, Japanese counterattacks pushed them back to their original positions by nightfall. In the second week of July, Song deployed the 82nd and 103rd Divisions for an attack against Kanemitsu’s southwest defenses, initially achieving success but ultimately being repelled by Japanese counterattacks.
In the meantime, the Pingda garrison, devastated by cholera, was reaching its breaking point. Consequently, the Matsui Force was dispatched to provide relief on July 11, successfully reaching their designated gathering point northwest of Pingda after a challenging two-day march. On July 13, Matsui's initial assaults only secured the forward positions of the 226th Regiment; however, the following day, they managed to breach the Chinese defenses, delivering much-needed supplies to the Pingda Garrison and evacuating its sick patients. Having performed its mission, the Matsui Task Force started its return trip on the morning of 15 July. The following evening, an enemy group was discovered near Chungchai and the Task Force prepared to attack. Just before the actual launching of the attack, Col. Matsui received a message from division headquarters stating that, "A powerful enemy force is advancing toward Mangshih. The Matsui Force will return as soon as possible."
To the north, Song opted to halt the sporadic attacks and initiated a synchronized assault with his four divisions on July 23. Backed by intense artillery fire, the Chinese exerted significant pressure, eventually overrunning the Hondo Position by the end of July. Only the timely intervention of Japanese fighters halted the offensive. Further north, following the subsiding of the storms and a heavy air bombardment, Huo finally launched a general offensive on July 26, supported by artillery and mortars. Moving swiftly and with strength, the Chinese successfully demolished all fortifications on Laifeng Hill, compelling the Japanese, grappling with ammunition shortages and heavy casualties, to abandon their other outposts in the vicinity.
The Chinese attack that followed revealed that previous experiences with Japanese positions had not been wasted. The Chinese infantry moved off quickly, on time, and as whole regiments rather than squads committed piecemeal. Mortar and artillery fire was brought down speedily on suspected Japanese positions, and the infantry took full advantage of it by advancing again the minute it lifted. Having taken one pillbox, the Chinese infantry kept right on going rather than stopping to loot and rest. At nightfall they were on top of the mountain and had taken a fortified temple on the summit. After mopping up the next day, the Chinese tallied about 400 Japanese dead. They themselves had lost 1200. Nevertheless, the speedy capture of Laifeng Hill was a brilliant feat of arms and dramatic evidence of the capabilities of Chinese troops when they applied proper tactics While the simultaneous attack on the southeast wall of Tengchong did not breach the massive wall, the Chinese now held a solid position in the sparse cluster of mud huts just outside the wall. Yet that will be all for today for the Burma-Yunnan front as we now are heading over to the Marianas.
As we remember, Admiral Spruance devised a plan to initiate the invasions of Guam and Tinian following the capture of Saipan. Tinian's strategic significance stemmed from its close proximity to Saipan and its relatively flat terrain, making it more suitable for bomber airfields compared to its mountainous counterpart. However, its natural features also posed challenges for a seaside landing, with most of its coastline characterized by steep cliffs. Consequently, the American forces had limited options for landing: the well-defended beaches of Tinian Town, particularly the northeast Yellow Beach at Asiga Bay, or the less fortified but narrow White Beaches on the northwest coast. However, the latter option risked congestion and immobility due to the confined space. After assessing the landing beaches firsthand, they opted for the latter, anticipating lower resistance. General Smith's Northern Landing Forces were tasked with this operation, although there were some changes in the chain of command. Smith was appointed commander of Fleet Marine Force, Pacific, overseeing all Marine Corps combat units in the region. General Schmidt assumed command of the 5th Amphibious Corps and the Northern Landing Forces, while Major-General Clifton Cates replaced him as commander of the 4th Marine Division. Additionally, Admiral Hill assumed command of a reorganized Northern Attack Force for the amphibious assault.
The strategy outlined was for Cates’ 24th and 25th Marines to land on the White Beaches on July 24, securing a beachhead line encompassing Faibus San Hilo Point, Mount Lasso, and Asiga Point. This offensive would receive heavy artillery support from Saipan, as well as backing from carrier-based aircraft, Aslito airfield-based planes, and naval gunfire. One of the main justifications for the final decision to land over the unlikely beaches on the northwestern shore of the island was the feasibility of full exploitation of artillery firing from Saipan. Consequently, all of the field pieces in the area except for the four battalions of 75-mm. pack howitzers were turned over to 14th Corps Artillery during the preliminary and landing phase. General Harper arranged his 13 battalions, totaling 156 guns and howitzers, into three groupments, all emplaced on southern Saipan. Groupment A, commanded by Col. Raphael Griffin, USMC, consisted of five 105-mm. battalions, two each from the Marine divisions and one from V Amphibious Corps. It was to reinforce the fires of the 75-mm. pack howitzers and be ready to move to Tinian on order. Groupment B, under the 27th Division's artillery commander, General Kernan, was made up of all of that division's organic artillery except the 106th Field Artillery Battalion. It was to reinforce the fires of Groupment A and also to be ready to displace to Tinian. Groupment C, commanded by General Harper himself, contained all the howitzers and guns of 24th Corps Artillery plus the 106th Field Artillery Battalion. It was to support the attack with counterbattery, neutralization, and harassing fire before the day of the landing, deliver a half-hour preparation on the landing beaches immediately before the scheduled touchdown, and execute long-range counterbattery, harassing, and interdiction fire.
Concurrently, General Watson’s 2nd Marine Division would stage a feint near Tinian Town before landing behind the main assault force post-beachhead establishment. Meanwhile, General Griner’s 27th Division would remain on standby in corps reserve, ready to embark on landing craft at short notice. A notable logistical innovation for Tinian involved a dual shuttle system to prevent congestion. Loaded trucks and Athey trailers shuttled between Saipan's base supply dumps and Tinian's division supply depots, while amphibious vehicles directly transported supplies from ship to shore to division dumps, aiming to minimize beachside handling of supplies. Additionally, General Geiger’s 3rd Amphibious Corps, comprising the 3rd Marine Division and the 1st Provisional Marine Brigade, assisted by Admiral Conolly’s Southern Attack Force, were tasked with capturing Guam. Due to formidable coastal defenses, Geiger's plan necessitated landings north and south of Apra Harbor on July 21, bypassing the heavily fortified Orote Peninsula.
General Turnage's 3rd Marine Division was tasked with landing on the shores between Adelup Point and the Tatgua River mouth, proceeding southward to occupy the eastern area of Apra Harbor. Simultaneously, General Shepherd's 1st Provisional Marine Brigade was to land between Agat village and Bangi Point, then pivot northward towards the base of the Orote Peninsula. The establishment of a secure beachhead line from Adelup Point to Facpi Point was crucial before Geiger's forces could launch their assault on Orote Peninsula and subsequently secure the rest of the island. With the 27th Division committed elsewhere, Major-General Andrew Bruce's 77th Division, slated to assemble at Eniwetok by July 18, was designated as the new reserve under Geiger's command. The 305th Regiment was assigned to land behind Shepherd's Marines to reinforce the beachhead line. To optimize support for the troops, Conolly divided his Southern Attack Force into two: his Northern Attack Group, backing the 3rd Marine Division's landing, and Rear-Admiral Lawrence Reifsnider's Southern Attack Group, aiding the 1st Provisional Brigade's landing. Coordination of pre-landing bombardments was planned between Conolly's ships and aircraft, synchronized with scheduled strikes by aircraft from Admiral Mitscher's Task Force 58.

The time had finally come for the Japanese home islands to be subjected to the horrors of modern bombing campaigns. It would begin gradually, but would escalate to a literal horror show that starved the population of Japan into submission. Meanwhile Hideki Tojo was finally sacked, though by no means was he gone.

- 138 - Pacific War - The Battle of Noemfoor, July 9-16,1944
9 7月· The Pacific War - week by week
Last time we spoke about the fall of Saipan. General Smith's coordinated attacks on June 27th led to significant progress, with the 4th Marine Division notably advancing. The 27th Division encountered resistance, and casualties rose. By early July, Americans gained ground, pushing toward Marpi Point. Japanese resistance remained fierce, but American forces steadily advanced, capturing strategic positions. The assault on Petosukara was swiftly countered, but intense action unfolded in the Makunsha region. The 3rd Battalion, 24th Marines faced a fierce enemy thrust, with over 200 attackers killed. Facing defeat, General Saito ordered a suicidal assault, resulting in a chaotic and desperate charge. Despite heavy losses, American forces repelled the onslaught. The battle lasted until midday on July 7, with sporadic skirmishes continuing. Efforts to persuade cave occupants to surrender intensified, yet many civilians chose mass suicide. Saipan was declared secured after extensive casualties on both sides.
This episode is the battle of Noemfoor

General MacArthur unleashed a new offensive, seeing General Patrick’s troops successfully landed on Noemfoor with little opposition, securing a beachhead. While the 3rd Battalion, 503rd Parachute Regiment was being airdropped on July 4, Colonel Sandlin’s 3rd Battalion continued eastward through scattered minefields toward Kornasoren Drome, meeting no resistance. Simultaneously, the 1st Battalion crossed the Kamiri River and occupied Kamiri village without encountering any opposition. Moving out of Kamiri, the American forces followed a southeastern road to a sizable Japanese garden area, where they faced resistance on Hill 201.
The Japanese garden area was about 600 yards long, east and west, and 350 yards across, north to south. The ground was devoid of large trees except for a few atop Hill 201, but thick, secondary jungle growth covered the eastern and southern slopes of the hill, while the rest of the garden area was overgrown with partially cultivated papaya, taro, and cassava, all averaging about eight feet in height. The trail from Kamiri village passed over the southern slope of Hill 201, and 300 yards away, near the eastern edge of the gardens, joined the main road from Kamiri Drome to Namber Drome, located about six miles to the south. Another trail ran along the eastern side of the hill, branching to the north and northwest at the northeastern corner of the low terrain feature.
To counter this, a double envelopment tactic was initiated, with Company C seizing Hill 180 to the north while Company B pushed the Japanese southeast over Mission Hill, a lower terrain feature situated southeast of Hill 201. By 15:15, the battalion secured the ground on both flanks of Hill 201 and consolidated around the hilltop for the night, establishing a tight defensive perimeter. At 05:20 on July 5, the Japanese launched an attack along the southern and southeastern sides of the perimeter with mortar support. The American forces responded with a deadly barrage of mortar and artillery fire, driving the enemy back and neutralizing their machine-gun positions. Some Japanese managed to get through the mortar and artillery barrages and continued up the sides of the trail from the south through fire from Company D's machine guns. The enemy found cover behind a low, 150-yard-long log fence which led from the southeast toward the center of the 1st Battalion's defenses. While the fence afforded some protection, the attacking infantrymen were silhouetted as they tried to clamber over the top. The main body of the attacking force therefore kept down behind the fence, trying to crawl along it to the top of the hill. Advancing cautiously, the attackers encountered sustained machine-gun and rifle fire from the defenders atop the hill, as the fence did not extend beyond the outer defenses of the 1st Battalion.
The assault quickly deteriorated into a sequence of small suicide charges carried out by groups of three to six Japanese soldiers. The 1st Battalion now sent patrols out over the battlefield. From prisoners it was determined that the attacking force had consisted of 350 to 400 men--the 10th and 12th Companies, 219th Infantry, reinforced by approximately 150 armed Formosan laborers. During the morning over 200 dead Japanese were counted around the 1st Battalion's perimeter, and the number of enemy dead found or enemy wounded captured on subsequent days along trails leading south from the hill indicated that virtually the entire original attacking force had been annihilated.
By 06:30, the skirmish had concluded, with over 200 Japanese casualties tallied. Following this engagement, operations on Noemfoor transitioned into a series of patrol activities as Allied forces extended their dominance over the island and rapidly expanded the airfield facilities. On the morning of July 6, Sandlin’s 2nd Battalion executed an amphibious landing on the deserted Namber Drome following a brief naval bombardment. By July 10, intensive patrolling had only encountered small Japanese groups, leading Patrick to conclude that no significant organized enemy presence remained on Noemfoor. To eradicate the remaining opposition, the 503rd Parachute Regiment was dispatched to the island's southern sector while the 158th addressed the northern half. By the end of August, Sandlin’s efforts had resulted in the death of 611 Japanese soldiers, the capture of 179, the loss of 6 American lives with 41 wounded, and the liberation of 209 slave laborers.
The Japanese had never brought the Melanesians of Noemfoor entirely under their control, for the natives had either offered a passive resistance or had faded into the interior to live off the land. A few were impressed into service by the Japanese, while others who were captured but still refused to cooperate were executed. The natives greeted the Allied landings with great enthusiasm and came out of hideaways in the hills carrying Dutch flags which they had concealed from the Japanese. Under the direction of the Netherlands Indies Civil Administration, the natives were gradually resettled in their old villages. Late in July the village chiefs gathered in formal council and officially declared war on the Japanese. Thereafter, native cooperation increased. Up to August 31 the natives had captured and brought to Allied outposts more than 50 Japanese and had killed another 50. One tale of horror concerns the Javanese on Noemfoor. According to information gathered by the NICA Detachment, over 3000 Indonesians were shipped to Noemfoor in late 1943, mostly from Soerabaja and other large cities on Java. The shipment included many women and children. The Japanese, without regard to age or sex, put the Javanese to work constructing roads and airfields almost entirely by hand. Little or no clothing, shoes, bedding, or shelter was provided, and the Javanese had to supplement their very inadequate allowance of rations by shifting for themselves. Driven by hunger, many attempted to steal Japanese rations but for their pains were beheaded or hung by their hands or feet until dead. Starvation and disease took a steadily increasing toll. The dead were periodically collected for mass burial, and survivors alleged that many of the sick were buried alive. It was considered probable that not more than 10 or 15 Javanese were killed accidentally by Allied forces. Yet only 403 of the 3000-odd brought from Java were found alive on Noemfoor by August 31.
Meanwhile, Colonel Jones pursued the remnants of Colonel Shimizu’s Noemfoor Detachment to Hill 670 in the south. From July 13 to 16, both sides engaged in fierce combat for control of the hill, with the Japanese ultimately managing to evade capture. Contact was reestablished on July 23 near Inasi, but Shimizu eluded capture once more. The primary Japanese force was finally located on August 10 near Hill 380, prompting Jones’ 1st and 3rd Battalions to converge in an attempt to trap the enemy. However, on August 15, Shimizu once again evaded capture, slipping away towards Pakriki.
Although the Japanese forces were either captured or eliminated by August 17, Shimizu evaded capture or death and remained at large by the operation's conclusion. Jones' forces endured 57 fatalities and 302 injuries, but managed to neutralize over 1100 Japanese soldiers and apprehend approximately 560 individuals, while liberating an additional 194 enslaved laborers. This brings the total casualties for the Battle of Noemfoor to 1730 Japanese casualties, with 740 taken prisoner, and 63 American fatalities, 343 wounded, and 3 missing, alongside the liberation of 403 slave laborers. Transitioning to the developments on the Aitape front post-Operation Persecution, significant changes occurred under General Gill's command starting May 4. The defensive setup in the Aitape region was revamped, and Colonel Howe's 127th Regiment bolstered its eastern positions, with the Nyaparake Force extending patrols to the Danmap River. However, General Nakai's advance forces arrived in early May. Shortly after 2:00am on 14 May, after a short preparation by grenades, light mortars, and light machine guns, 100 to 200 Japanese of the 78th Infantry, 20th Division, attacked from the east against the coastal sector of the perimeter. This assault was broken up by rifle and automatic weapons fire and by lobbing mortar shells to the rear of the advancing enemy group. The Japanese disappeared into the jungle south of the narrow beach. For the next hour Captain Fulmer's mortars placed harassing fire into suspected enemy assembly points east of the small stream. Meanwhile, the eight-man outpost reported that many small parties of Japanese were moving up the beach within 300 yards of the main perimeter and then slipping southward into the jungle. Such maneuvers seemed to presage another attack. The second assault came about 0330, this time against the eastern and southeastern third of the defenses. The Japanese were again beaten back by small arms and mortar fire, but at 5:00am they made a final effort which covered the entire eastern half of the perimeter. This last attack was quickly broken up and the Japanese quieted down. About 7:30am on the 14th, elements of Company A, 127th Infantry, began moving into the forward perimeter to reinforce Captain Fulmer's beleaguered units. The 1st Platoon of Company C and the 81-mm. mortar section also moved forward in preparation for continuing the advance.
General Martin took charge of the East Sector on the same day, relocating all troops except the Nyaparake Force to the west bank of the Driniumor River. The East Sector forces were supplied by a variety of methods. Units along the coast were supported directly by small boat from BLUE Beach or by native ration trains moving along the coastal track. Supplies to the Afua area went south from the coast along the Anamo-Afua trail or, later, over the inland track from the Tadji fields through Chinapelli and Palauru. Wheeled transport was impracticable except along short stretches of the coastal track. In early June, when the Japanese ambushed many ration parties which attempted to reach Afua, experiments were made with air supply from the Tadji strips. Breakage and loss were heavy at first, but air supply rapidly became more successful as pilots gained experience and ground troops located good dropping grounds. A dropping ground cleared on the west bank of the Driniumor about 2200 yards north of Afua soon became the principal source of supply for troops in the Afua area. Communications during operations east of the Driniumor were carried out principally by radio, but between units along the river and from the stream back to higher headquarters telephone became the principal means of communication. Keeping the telephone lines in service was a task to which much time and effort had to be devoted. The Japanese continually cut the lines, or American troops and heavy equipment accidentally broke the wires. The enemy often stationed riflemen to cover breaks in the line, thus making repair work dangerous. Usually, it was found less time consuming and less hazardous to string new wire than to attempt to find and repair breaks. As a result, miles of telephone wire soon lined the ground along the trails or was strung along the trees in the Driniumor River area and back to the Tadji perimeter. Despite this adjustment, Nakai escalated pressure, advancing beyond Yakamul by month's end. In response, Gill replaced the Nyaparake Force with the 1st Battalion, 126th Regiment, which swiftly recaptured Yakamul and Parakovio. Despite initial success, Nakai's forces launched a heavy counterattack in early June, reclaiming Yakamul by June 5.
In the meantime, additional Japanese units had been conducting exploratory missions inland against Afua since the beginning of the month. However, Howe’s 1st Battalion ultimately succeeded in repelling them. This allowed Martin’s forces to establish an outer defensive line along the Driniumor River. From there, they continued forward patrols toward the Japanese lines. While the 41st and 51st Divisions struggled to move personnel and supplies to the forward assembly area, Nakai efficiently organized a counter-reconnaissance screen along Niumen Creek to prevent East Sector troops from gathering intelligence about deployments farther east. On June 20, due to the increasingly dire situation in Western New Guinea, the 18th Army was suddenly transferred from 2nd Area Army control to the direct command of the Southern Army. Although General Terauchi's directive was to execute a "delaying action at strategic positions," General Adachi opted to adhere to his original plans for a westward offensive. He was determined to maximize the effectiveness of his forces while they still possessed fighting capability, aiming to divert as much enemy strength as possible away from the Western New Guinea battlefront. Sensing an imminent heavy enemy assault, Generals Krueger and MacArthur decided to reinforce Aitape with General Cunningham’s 112th Cavalry Regiment, arriving on June 27, and Colonel Edward “Ted” Starr’s 124th Regiment, expected to arrive in early July. They also expedited the shipment of the 43rd Division from its New Zealand staging area to Aitape, necessitating the establishment of Major-General Charles Hall’s 11th Corps. Upon assuming command of the task force on June 29, Hall reorganized his forces and implemented several troop redeployments in preparation for the looming enemy attack.
By June 30th, Adachi had completed concentrating his forces in the assembly area. Consequently, he swiftly initiated preparations for launching an attack against the Driniumor River line on July 10th. His strategy involved Colonel Nara Masahiko’s 237th Regiment crossing the river and launching an assault westward towards Koronal Creek, and northwest to clear Anamo and other Paup villages. Meanwhile, the 78th and 80th Regiments were tasked with clearing the Afua area and advancing all the way to Chinapelli. Success in this endeavor would pave the way for Japanese units to advance towards the Tadji airstrips. Furthermore, a Coastal Attack Force was designated to carry out a diversionary maneuver along the coast, aiming to engage the enemy and constrain them with artillery fire.
In early July, as the Japanese finalized their preparations, Hall and Martin made the decision to dispatch robust patrols east of the Driniumor to the Harech River. However, these patrols were only able to advance as far as Yakamul, where they encountered only the enemy’s forward units. Consequently, on July 10th, Hall and Martin ordered the 1st Battalion, 128th Regiment, and the 2nd Squadron, 112th Cavalry to conduct a reconnaissance mission across the Driniumor. Subsequently, the infantry faced significant resistance as they pushed towards Yakamul, while the cavalry's progress was limited to about a mile due to the dense jungle terrain. Despite these efforts yielding disappointing results, a captured Japanese soldier disclosed that their attack was imminent that night. However, this critical piece of information was mistakenly disregarded by the American command, leaving Adachi and Nakai poised to launch their counteroffensive.
Around midnight, the assault commenced with the 1st Battalion, 78th Regiment charging across the Driniumor River, facing Company G of the 128th Regiment along a narrow front.
The Japanese attacked in two or three screaming waves, broadening the front after the first assault by throwing in the rest of the 78th Infantry and possibly elements of the 80th Infantry. Japanese reconnaissance had been good--the attackers knew the locations of company and battalion command posts all along the American defenses but not quite good enough. The enemy did not know that Company G had been reinforced during the afternoon of 10 July nor, apparently, had he discovered that the company's front was protected by low barbed wire. The attacks of the 78th Infantry were thrown back with heavy losses. Machine gun and mortar fire from the 2d Battalion, 128th Infantry, accounted for many Japanese, numbers of whom were caught as they tried to cross the barbed wire in front of Company G. According to Japanese sources, the results of American artillery fire were even more disastrous. As soon as the enemy attack had begun, the 120th and 129th Field Artillery Battalions had started firing previously prepared concentrations along the bed and east bank of the Driniumor. The Japanese units in or near the impact areas suffered heavy casualties. The 1st Battalion. 78th Infantry, was quickly reduced from 400 to 30 men, principally as a result of the American artillery fire, which also destroyed large numbers of artillery weapons, machine guns, and mortars.
Despite this, the Americans, skillfully backed by artillery support, ultimately repelled them with significant casualties. Following this initial repulse, Martin concluded that a reconnaissance in force was unnecessary and ordered the units involved to retreat behind the Driniumor River. Confusion among many Japanese units, arriving late, had delayed the commencement of the 80th Regiment's attack, which was directed at Company E and was similarly pushed back. But a second wave of attackers, probably comprising the 237th Infantry and heretofore uncommitted elements of the Right Flank Unit, began pouring across the Driniumor toward Company E at approximately 0200. The new attackers overran the company command post and surrounded most of the unit's widely separated strong points. Fighting continued in the company sector for a little while, but the unit could not long withstand the overwhelming enemy pressure. Company organization and communications broke down. Worse still, the troops began to run out of ammunition. A general withdrawal commenced.
By 03:00, the Japanese had breached a gap approximately 1300 yards wide in the American lines, physically occupying that territory. Fortunately, the following hours remained relatively calm as the 78th and 80th Regiments regrouped to the south to resume the offensive. This lull enabled Martin to dispatch the 1st Battalion, 128th Regiment to counterattack along the Anamo-Afua trail, aiming to reinforce the 2nd Battalion's positions. Initially encountering no resistance for the first 1500 yards, the Americans were eventually halted by intense enemy fire at 10:30, compelling them to retreat back to Tiver. This fierce opposition convinced Martin that the enemy could advance directly westward with minimal hindrance towards the Tadji strips unless he abandoned the Driniumor River line. He decided to reorganize his forces along the secondary delaying position at the X-ray River-Koronal Creek line, preparing for further counterattacks against the Japanese.
Accordingly, while Company F maintained their position along the coast, the 128th Regiment began to fall back towards the creek. Further south, Cunningham opted to withdraw his cavalrymen in two stages, successfully reaching X-ray by midnight. However, communication issues delayed Howe’s 3rd Battalion, with most of the unit arriving at the river the following day. A small contingent had to engage in combat with Japanese forces and couldn't reach X-ray until July 13. Despite this, Krueger and Hall disagreed with the decision to abandon the Driniumor, promptly deploying the 124th Regiment for a potential counterattack. Martin, who was instructed to hold his position, was replaced by Gill, assuming direct command of the divided covering force, now split into North and South Forces. However, before the American counterattack could commence, Nara’s infantry launched an assault towards Tiver and Koronal Creek on July 12. The 128th Regiment successfully repelled them after a fierce confrontation. Meanwhile, Adachi dispatched the main body of the 41st Division and the reserve 66th Regiment towards the Driniumor, augmenting pressure on the Paup coast. To the south, Nakai’s units gathered across the river near Afua and Kwamrgnirk, preparing for a final northward push. Finally, at 07:30 on July 13, the American counteroffensive commenced as the 1st Battalion, 128th Regiment swiftly moved from Tiver to Chakila, only to be ambushed by Japanese artillery. Nevertheless, precise artillery counterfire silenced most of the enemy artillery, enabling the Americans to advance eastward toward the mouth of the Driniumor.
Meanwhile, the 124th Regiment under Starr's command advanced southward along the Anamo-Afua trail, facing strong opposition from the 237th Regiment. Despite encountering resistance, they managed to reach the river, although still positioned considerably north of their designated centerline. Cunningham's South Force began its eastward movement from the X-ray River at 10:00, successfully overcoming enemy positions along several stream crossings to reach the Driniumor near Afua. Consequently, all original crossing points on the Driniumor fell to the Allied forces, isolating the 20th Division and the 237th Regiment several miles west of the river's bank. By nightfall, Nara had regrouped his 237th Regiment for another assault on the 2nd Battalion, 128th Regiment. Company E demonstrated its combat effectiveness by holding firm and repelling the Japanese forces, with the rest of the battalion successfully defending against subsequent small-scale attacks, marking the conclusion of Nara’s offensive actions. The following morning, Gill’s forces consolidated their defensive positions along the reformed river line, albeit with a 1500-yard gap remaining in the center. Yet this all for today with Noemfoor as we now need to head over to the India-Burma theater.
The final phase was coming for the Battle of Imphal. By the start of July, the reopening of the Imphal–Kohima Road facilitated the resupply of the 4th Corps, enabling them to launch an offensive against the fatigued and under-resourced troops under General Mutaguchi's command. Additionally, three brigades from General Stopford’s 33rd Corps advanced from the north, swiftly joining General Gracey’s 20th Division in an endeavor to reopen the Ukhrul Road.
Under intense pressure, General Yamauchi’s battered 15th Division units hastily abandoned Tongou and Sokpao, leading to the 80th Brigade occupying Lamu by July 2. The next day, the ailing general, who had long fallen out of favor with Mutaguchi, was carried from the battlefield on a stretcher and later died in a hospital at Maymyo. Lieutenant-General Shibata Uichi replaced him and promptly prepared the 51st and 67th Regiments to retreat. To cover their withdrawal, the newly arrived and utterly exhausted 60th Regiment was tasked with attacking towards Lamu, while General Miyazaki’s troops assembled behind Ukhrul. However, the 60th Regiment was so weakened that its attacks were easily repelled, and the 67th Regiment retreated in disorder, leaving the 51st encircled. On July 8, Colonel Omoto’s troops fiercely broke through the encirclement in three columns, allowing Stopford’s brigades to finally overcome Japanese resistance at Ukhrul and capture the town. This forced Shibata to regroup his forces along a new line from Lungshong through Sangshak to Sakok, ultimately enabling the British-Indian forces to reopen the Ukhrul Road by July 10. With both supply roads reopened, the arrival of Stopford’s brigades from the north, and the Japanese forces nearly routed, General Slim decided it was time to go on the offensive. Slim's plan involved the 33rd Corps taking over the Shenam Saddle and the Tamu–Palel Road while the 4th Corps cleared the Japanese from the Silchar Track and the Tiddim Road.
On the other hand, Mutaguchi was still planning a combined attack on the Palel area involving the 15th Division, remnants of the 31st Division, and some units from the 33rd Division. Although he issued an attack order, the divisions were too battered to comply. The overall situation of the 15th Army went from bad to worse and the only hope remaining was to rally the 31st at Humine, give the troops a few days rest and then, after a reorganization, to dispatch them to the northern flank of the Yamamoto Detachment to capture Palel. In early July the 31st Division was concentrated in the area east of Myothit but discipline had disintegrated to the point that the Division could scarcely be termed a combat force. The Torikai Unit was organized with the 138th Infantry Regiment (less one battalion); the 2d Battalion, 124th Infantry Regiment and one artillery battalion to reinforce the Yamamoto Detachment. At the same time,the 15th Army ordered the 33rd Division to attack Palel from the south with the 214th Infantry Regiment. The newly formed Torikai' Unit, however, failed to join the Yamamoto Detachment and the order for the 33rd to attack Palel was never carried out.
Consequently, on July 9, General Kawabe had no choice but to order preparations for a withdrawal to a line connecting the Zibyu Mountains, Mawlaik, Kalewa, and Gangaw. Mutaguchi intended to begin the retreat on July 16, directing the 15th Division towards Sittaung, the 31st Division to Thaungdut, and the 33rd Division to Tiddim, while the Yamamoto Detachment would hold the Shenam Saddle until July 24 and then retreat to the Kuntaung-Moreh line to cover the main Army's withdrawal from the Kabaw Valley.
On the southwest front, General Tanaka’s forces had already started retreating from the Bishenpur area, leaving a small covering force at Ningthoukhong to prevent a pursuit by the 17th Division. As a result, General Cowan’s brigades made limited progress against the stubborn rearguard, ultimately securing Ningthoukhong on July 16 after heavy bombardment, coinciding with Mutaguchi’s general withdrawal. By the middle of July, Japanese resistance centered on Ningthoukhong Kha Khunou. A small hamlet about 300 meters wide and 500 meters long, it lay to the immediate south of Ningthoukhong. Despite probing attacks by the 48th Indian Brigade’s infantry and artillery firing on their defenses, the Japanese held on. Finally, in the early hours of 16 July, this small space was subjected to what some describe as one of the heaviest artillery concentrations yet in the Burma Campaign; in the space of an hour, approximately 9,000 shells were fired on Ningthoukhong Kha Khunou. Fortunately for the Japanese, they had withdrawn from the village just before the shelling began. By the time it ended, the village had been completely flattened and was pockmarked with waterlogged craters. And so the last Japanese stronghold in the Imphal Valley was taken. The 63rd Indian Brigade also reached and occupied the Laimanai area around the same time. The 5th Indian Division, the other division in the reconstituted IV Corps, now took over and commenced the chase of the Japanese 33rd Division down the road towards Tiddim.
The 5th Division, now led by Major-General Geoffrey Evans, continued the pursuit while Stopford’s brigades harassed the disordered retreat of the 15th and 31st Divisions. Despite their efforts, the 15th and 31st Divisions reached Thaungdut by early August, and the 33rd Division managed to assemble around Chikha by mid-August, under significant pressure and the serious threat of having their withdrawal route cut off. The 33rd Division distinguished itself by displaying almost superhuman fighting power and repeatedly launched counterattacks against the pursuing British-Indian 5th Division. The Yamamoto Detachment, however, had failed to cover the Yazagyo area and, in mid-August the 33rd Division found itself the vicinity of Chikha facing the serious threat of having its route of withdrawal cut by the enemy which was infiltrating into the Yazagyo area from Moreh and Shuganu through the Kabaw Valley.
On the south-eastern approach to Imphal, the two armies continued to face each other on the Shenam Saddle. Yamamoto Force remained in place on these heights and the front line was still on Scraggy. It was in the second half of July that a final, concerted effort was made to evict Yamamoto Force and push it down the Tamu–Palel Road towards the India–Burma frontier. Led by the 23rd Indian Division , the operation involved five brigades in a three-pronged attack. The central thrust was by the 37th Indian Brigade on the Shenam Saddle, with the support of all available artillery and tanks; the 5th British Brigade was deployed behind it and readied to provide assistance. D-day was to be 24 July. The 1st Indian Brigade was sent through the hills on the right, to arrive behind the saddle. The two were to push the Japanese back on the road. It was hoped their withdrawal route would be cut by the 49th Indian Brigade, which would arrive on the road after looping in from the far left; the 268th Indian Brigade would be to its left, protecting its flank.
Before the Japanese could retreat, the 49th Brigade had cut off General Yamamoto’s withdrawal route by looping in from the far left. However, Mutaguchi had sent Colonel Sato Genpachi’s reserve 61st Regiment to Tamu, which quickly counterattacked and reopened the route. Consequently, Yamamoto withdrew to Moreh, allowing Roberts to swiftly capture Nippon Hill and Scraggy. Within two days, the 23rd Division advanced down the road, forcing the Yamamoto Detachment to retreat toward Mawlaik on July 30. This marked the end of the Battle of Imphal and Operation U-Go, the Japanese Army’s largest land defeat. Estimates vary, but about 30,000 Japanese soldiers died and 23,000 were injured during the operation, including 6,000 killed at Kohima and 16,000 at Imphal. Additionally, the INA lost about 2,000 dead and 2,000 wounded. On the other hand, the British-Indians suffered 16,000 casualties, with over 12,000 at Imphal. Though Mutaguchi’s plan was initially effective and nearly succeeded in capturing Imphal, he underestimated the enemy’s ability to resist his troops and quickly bring reinforcements. Slim’s overall strategy for Imphal succeeded, as the Japanese overextended themselves from the Chindwin River to the Imphal Valley, just as he had predicted. A crucial factor in the British-Indian success was the air support, which kept the 14th Army supplied despite the road to Kohima being cut off. Ultimately, in an attempt to thwart a potential British-Indian advance into Burma, Mutaguchi’s 15th Army was utterly decimated by the failed attempt to capture Imphal. This failure allowed Slim to seize the moment and launch a rapid offensive into Burma, countering the Japanese U-Go plan. The Allies thus gained the upper hand, marking the beginning of the end for Japanese control over Burma.
As a final note for this week by late July, Admiral Somerville executed Operation Crimson, a coordinated naval and air assault on Japanese airfields in Sabang, Lhoknga, and Kutaraja. Departing Trincomalee on July 22, Somerville’s Task Force 62, comprising two carriers and four battleships, arrived off Sabang on the morning of July 25, ready to commence the bombardment. On 5th July 1944 the carriers Victorious and Indomitable arrived in Colombo. The former sailed with Illustrious on 22 July for Operation ‘Crimson’, a bombardment of Sabang by the battleships over which the carrier-borne aircraft were to provide cover and take photographs of the damage. Illustrious embarked the same aircraft as before with Victorious for a total of thirty-nine Corsairs; together they comprised 47 Naval Fighter Wing commanded by Lieutenant Commander Turnbull. The force assembled for the operation was designated TF 62 and the carriers were supported by Queen Elizabeth, Valiant, Renown, Richelieu, Nigeria, Kenya, Gambia, Ceylon, Cumberland, Phoebe, Tromp, Relentless, Rotherham, Racehorse, Raider, Roebuck, Rocket, Rapid, Quilliam, Quality and Quickmatch. The submarines Templar and Tantalus were deployed to ASR positions. The carriers operated only thirty-five miles north of Sabang, not far from the battleships, which approached their bombardment positions at 06:40.
The initial launch was planned for thirty-three minutes before sunrise but this proved to be too early as the morning was exceptionally dark and the launch was delayed for five minutes. Even then it was too early and the form-up was clumsy and slow, delaying departure. The fighters were briefed to attack Sabang, Lho Nga and Kotaraja airfields but 1838 NAS made a bad landfall since maps lacked detail and no photographs were available. When the target airfields were found it was still too dark for accurate strafing but the enemy was alert and opened fire as soon as aircraft came within range. To aircrew accustomed to the excellent intelligence material by then available in the Home Fleet, this caused concern and it had to be accepted that it was difficult to obtain good targets without losing the element of surprise. At very low level on a dark morning, flying at 400 knots with flashes from antiaircraft gunfire all around, camouflaged aircraft in revetments were inconspicuous and the strafing runs were not a success. One Corsair was shot down but the pilot was rescued.
Concurrently, the battleships targeted harbor facilities and military barracks at Sabang, while cruisers and destroyers shelled radar and wireless stations and engaged enemy shore batteries. After the main bombardment, the destroyers Tromp, Quality, Quickmatch, and Quilliam entered Sabang harbor, attacking Japanese positions and launching torpedoes, sustaining light damage from return fire. On the return journey, two enemy reconnaissance aircraft were intercepted and shot down by fighters. Additionally, ten Zeros attacked Somerville’s convoy but were intercepted by 13 Corsairs, leading to two Zeros being shot down and another two damageFollowing this engagement, British pilots noted that the Japanese airmen were not as proficient as they had been in 1942.
Although Operation Crimson's outcomes were not spectacular, Somerville’s final offensive was still deemed successful enough. Due to health concerns, he was subsequently transferred to diplomatic duties at Admiral Mountbatten’s request. Currently, Admiral Mountbatten was moving toward a complete rearrangement of the higher officers in SEAC. From the time of his arrival in the Far East, he had had trouble with his three commanders in chief. When the Imphal crisis arose, Mountbatten was dissatisfied with General Giffard's conduct of operations, and when he later found Giffard taking what Mountbatten considered a highly negative approach toward an aggressive conduct of operations he resolved to ask for Giffard's relief. Mountbatten's relations with Admiral Somerville had been equally difficult. Somerville had refused to treat him as a Supreme Commander and in Mountbatten's opinion tried to make him simply the chairman of a commanders-in-chief committee. As for the RAF commander, Air Chief Marshal Peirse, Mountbatten was not seeking his relief because he did not wish to change all of his principal subordinates simultaneously. After his relief, Somerville was placed in charge of the British naval delegation in Washington DC in October 1944 where he managed—to the surprise of almost everyone—to get on very well with the notoriously abrasive and anti-British Admiral Ernest King, the United States' Chief of Naval Operations.

- 137 - Pacific War - Fall of Saipan, July 2-9,1944
2 7月· The Pacific War - week by week
Last time we spoke about operation forager and the Changsha-Hengyang campaign. On Saipan, General Holland Smith's forces advanced with the 4th Marine Division targeting Hill 600 and the 2nd Marine Division capturing Mounts Tipo Pale and Tapotchau. The 27th Division supported these efforts, encountering resistance and challenging terrain. Meanwhile, the 27th Division, under new leadership, made progress despite difficulties. Concurrently, Japanese forces initiated a three-pronged assault in Hunan, capturing significant territory despite supply challenges and heavy rain. On June 11, the 40th Division took control of Yiyang while the 34th Division moved toward Yuelu Mountain. The 68th and 116th bypassed Changsha towards Guanqiao, with the 3rd and 13th facing resistance near Liuyang, which fell on June 14. Xue Yue retreated to Liling as Chinese defenses crumbled. Concurrently, the U.S. initiated Operation Matterhorn, targeting Japan's industrial sites. Despite challenges, the initial bombing runs prompted further strategic bombings, marking a significant phase in the Pacific War.
This episode is the Fall of Saipan

As we last saw, the Americans had begun their advance into Central Saipan. They achieved significant success on the right with the 4th Marine Division, but faced difficulties breaking through on the left and center. Following the victory in the Philippine Sea, Admiral Turner successfully completed unloading operations, landing approximately 60,000 troops and 75,000 tons of supplies by June 26. To maintain air superiority, Admiral Mitscher conducted raids on the islands of Pagan, Tinian, Guam, Rota, and Iwo Jima, and continued these raids over the next few days, despite ongoing Japanese night air attacks against the American beachhead.
In a strategic effort to keep the Japanese unsettled and unable to prepare for counterattacks, Carrier Task Group One raided Pagan Island on June 23rd. The neighboring islands in the Marianas were also not ignored; almost daily photo reconnaissance missions were conducted over Guam and Tinian to monitor any changes in their situation or positions before the landings. On June 25, Carrier Task Group Three carried out intense bombing raids on Guam and Rota to further incapacitate the airfields and installations there.
The first significant naval raid following the battle, beyond routine operations, was an attempted strike against the Volcano-Bonin group, which escalated into a substantial air battle initiated by the Japanese. At 6:00 on June 24th, Vice Admiral Joseph J. Clark's Task Group 58.1, comprising the Hornet, Yorktown, and Bataan launched a long-range fighter sweep of 48 Hellcats against Iwo Jima, which was intercepted by numerous enemy fighters. In the ensuing battle, four U.S. Hellcats were lost, while Japanese losses were estimated at 68 fighters and bombers. Despite this defeat, the Japanese attempted another attack against Clark's task group with the remnants of their local air force. This attempt ended disastrously for them, as U.S. interceptors shot down an additional 46 aircraft, bringing the day's total to 114. Task Group 58.1, having completed its mission without bombing the airfields, safely returned to Eniwetok without incident.
On the opposing side, after the fall of Mount Tapotchau, General Saito organized a final line of resistance between Tanapag, Radar Hill, and Tarahoho. In a brief resume on the morning of 27th June, Major General Igeta summarized the situation: “The summit of Tapotchau was occupied yesterday evening. Front line units tried to retake it with a night attack, but did not succeed as planned. In Donnay the enemy broke through with a number of tanks, but their advance was slow. Thereafter, no great change in the situation. The defense force, along with the firmest possible defense of its present front line and its activities toward annihilation of the enemy, is at present setting up with a line between Tanapag--Hill 221 (Radar Hill)--Tarahoho as the final line of resistance… Meanwhile, about 50 men of the 118th Infantry are improving their positions on the east side of Hill 343, and one company of the 136th Infantry is improving its position on Hill 268, and about 50 men of the 118 Infantry are digging in on the north side of that hill. The main body of the 9th Expeditionary Force, about 200 men, and about 100 men from the 9th Tank Regiment are consolidating their positions north and east of there in the high ground (Chacha water area).”Although the pre-landing preparations had been largely ineffective, continuous naval bombardment during the battle forced his troops to stay low and defend under intense pressure.
For the June 27 attack, General Smith ordered the three divisions to advance side by side and capture the O-6 Line. On General Schmidt’s front, progress was swift. The 23rd Marines advanced quickly, facing only sporadic rifle fire from the villages of Donnay and Hashigoru, and reached their objective. Meanwhile, the 165th Regiment moved rapidly through the hills but struggled to maintain contact, requiring the deployment of a battalion from the 24th Marines to fill the gap and repel an enemy tank attack. In the center, the 106th Regiment encircled Hell’s Pocket and established a cordon at the north end of Death Valley, although they made little progress against Hill Able. To the left, General Watson’s Marines advanced about 200 yards along Mount Tapotchau's western slopes while the division realigned its lines.
Despite largely ineffective pre-landing preparations, the continuous naval bombardment during the battle forced enemy troops to stay under cover and defend under intense pressure. In General Saito’s words “The practical experiences of the defense forces of Saipan… have to do with the power of the enemy naval bombardment. If there just were no naval gunfire, we feel with determination that we could fight it out with the enemy in a decisive battle.” Underwater mines, which the Japanese had used as land mines, were found along the road and railroad in the vicinity of Donnay. Tanks detoured these mined areas without difficulty, however. A Japanese supply dump, found near Hashigoru, contained new clothing, ammunition, and infantry weapons. Lieutenant Colonel Dillon's 2nd Battalion, moving through the matted vegetation and ragged cliff line along the coast, experienced difficulty keeping abreast of the faster-moving 3d Battalion. Since a detailed search of the gnarled coast line could not be instituted without sacrificing the momentum of the attack, Colonel Jones ordered the 1st Battalion to follow Dillon's unit at 400 yards, mopping up and investigating suspicious areas. By 4:40pm the 23rd Marines had trudged to objective O-6. Both battalions immediately dispatched security-reconnaissance patrols to their front but made no contacts with the enemy.
The next day, Major-General George Griner arrived to assume command of the 27th Division, immediately reorganizing his units and deploying the reserve 3rd Battalion, 105th Regiment. The 3rd Battalion, 106th Regiment had suffered heavy casualties in its Death Valley fight. By June 28 its effective strength of riflemen numbered approximately 100, and it was reorganized into a single rifle company. Among the 3rd Battalion's casualties on June 28 was the commanding officer, Lieutenant Colonel Harold I. Mizony, USA, killed in action when two Japanese tanks unexpectedly appeared just forward of his battalion observation post. By chance, the two enemy vehicles had found a lucrative target; commanders of the 2nd and 3rd Battalions, together with their company commanders, were gathered to plan the next move. Tightly grouped a short distance behind them were the men of the two battalions, waiting for the orders that would send them into action. Within a matter of moments the enemy tankers reaped an awful harvest, including 12 killed and 61 wounded, and then disappeared unscathed.
On General Watson’s front, Major Hunt's 2nd Battalion continued to fight across the open canefield toward its objective, a low ridge line north of Tipo Pale. Japanese riflemen and machine gunners, secure in their hillside grotto, raked the clearing with grazing fire. Light flame-thrower and medium tanks were available to the 6th Marines, but their use in this instance was limited because of difficult routes of approach to enemy positions, and support had to be delivered from long ranges. This left the task to the infantrymen. As everywhere demonstrated, reduction of cave positions proved a slow, painful job. By late afternoon the situation had improved slightly and the volume of Japanese fire had diminished somewhat, but the 2nd Battalion's unceasing efforts since 6:30 found it still short of the ridge line objective and very tired. A great store of energy had been burned in moving across the murderous field, yet more effort would be required. It appeared that the Japanese were rooted to the pock-marked ridge line. The Tipo Pale strong point, at which Company K, 6th Marines, had been whittling for many days, finally was secured on 28 June, permitting the company to rejoin its battalion. The tenacious Japanese soldiers in this pocket had sold their lives but had exacted from the 6th Marines a high price in time, men and effort.
The 8th Marines encountered tough Japanese resistance and difficult terrain while advancing against four small hills known as the Pimples, achieving minimal progress. Meanwhile, Schmidt, positioned well behind the 27th Division, received orders to maintain current positions. However, the 23rd Regiment conducted patrols beyond its lines up to 500 yards, and the 165th Regiment secured Hill 700 to complete the movement to the O-6 Line. Over the following two days, combat fatigue and the need for the 27th Division to catch up slowed the Marine divisions almost to a halt. Beginning their attack at 11:00 on June 29, the 3rd Battalion, 105th Regiment successfully closed the gap on Griner’s right flank by about 800 yards, eventually linking up with the 24th Marines the next day. On the left, the 106th Regiment encountered heavy resistance but eventually captured Death Valley and Hell’s Pocket, establishing contact with the 8th Marines by June 30. Behind them, the 2nd Battalion, 165th Regiment secured Hill Able and the remaining portion of Purple Heart Ridge. Meanwhile, the Marines and the 165th Regiment conducted patrols, cleared out remaining enemy forces, and fortified their positions. The 6th and 8th Marines also made some limited progress northward, culminating in the capture of Bill’s Pimple.
During the night of June 30, the Japanese commenced their withdrawal towards Saito’s final defensive line in an organized manner despite facing artillery fire. This new defensive line, though shorter, provided an opportunity for Saito to regroup his troops and strengthen their defense. However, failure to hold this position would spell disaster for him and his soldiers. Upon learning of the Japanese retreat, the American forces resumed their offensive on July 1, encountering stubborn resistance from remaining Japanese pockets that needed to be cleared out. The following day, General Smith's forces launched a coordinated attack. On the left flank, Colonel Stuart’s 2nd Marines swiftly advanced through Garapan, Flametree, and Sugarloaf Hills, while the 6th Marines made significant gains after neutralizing an enemy stronghold. The 8th Marines, after securing the Pimples, faced heavy Japanese resistance at Limestone Hill. In the meantime, evacuation of casualties had become a problem: Marines had fallen on the open field, and all attempts to rescue them only resulted in more men being hit. The scheme finally adopted, and the one which brought success, was for a tank to position itself between the casualty and the limestone hill. By following directly behind the tanks, hospital corpsmen could then move safely to the wounded, apply hasty bandages, give them a shot of morphine, and place them on stretchers. Then, carefully coordinating their moves with the tank by talking to the driver through the sound-powered phone on the rear sponson, the stretcher bearers would precede the tank from the site, all the while shielded from Japanese fire. White phosphorous rounds dropped on the hill by the 81mm mortar platoon plus frontal blasts from the chaperoning medium tanks also contributed to the success of this resourceful project. The fact that only small arms fire spattered against the thick hulls of the tanks indicated that the Japanese had no heavier weapons readily available in the limestone hill. By dark, all wounded had been rescued, but the task of seizing the hill still remained.
Only a clever night tank raid, utilizing illuminating shells and flamethrower tanks, could eliminate this stubborn Japanese position. In the center, the 106th Regiment advanced despite sporadic fire, while the 105th Regiment had to overcome the Papako strongpoint to make modest gains. With the arrival of the 27th Division at the O-6 Line, the right units could resume their advance. Consequently, the 165th Regiment encountered minimal opposition, advancing 1700 yards, while the 23rd and 24th Marines made virtually unopposed progress to the intermediate O-6A Line.
On June 3, the general offensive persisted, now targeting the O-7 Line. On the front under Watson's command, the 2nd Marines successfully took control of the remaining portions of Garapan, though they encountered difficulty clearing Mutcho Point on the town's northwestern edge. Duty in the town had little to commend it; battered skeletons of what had once been buildings, and humans, and animals, dotted the area; the choking smell of death hung about like a fog. And everywhere were the pieces of corrugated iron which the Japanese and natives had used as roofing for almost every structure from the hen house to the bank. To step on one of these huge rattling sheets was to inform everyone thereabouts of one's presence. Garapan's trash and garbage dump appearance was further enhanced by odd clothing, shoes, papers, books, and miscellaneous bric-a-brac strewn through the area. Perhaps the only bright point was the copious wells, providing adequate water for the 2nd Marines to bathe away some of the filth on their bodies.
The 6th Marines also advanced, halting 1000 yards from the coast, while the 8th Marines faced minimal resistance and gained approximately 1000 yards. Meanwhile, Schmidt's three regiments advanced side by side and in formation, making swift progress over challenging terrain but were ultimately halted before Hill 721 and 4th of July Hill. Nonetheless, the 24th Marines managed to capture Radar Hill, situated at the center of Saito’s final defensive line.
In the central area, Japanese delaying units hindered the 27th Division's progress towards the coast, with the 106th advancing another 1000 yards and the 165th about 500 yards. During the night of July 3rd the 165th Infantry command post became the scene of violent activity when 27 Japanese advanced into the installation, apparently by mistake. All of the Japanese intruders were killed with no loss to personnel of the 165th. In the morning, when an identification could be made, Colonel Ogawa Yukimatsu, commander of the Japanese 136th Infantry, was discovered among the dead. Piecing the story together, it appears that Ogawa and his headquarters group had been by-passed by U. S. advance and that he was attempting to displace to the northeast when he blundered into the 165th's command post. Detailed instructions pertaining to the establishment of Saito’s final line of defense were found on his body, providing the Americans with valuable intelligence for future operations.
The next morning, Griner’s forces continued their northward advance, successfully securing Flores Point and the surrounding high ground. To the right, despite a disappointing artillery barrage, Schmidt's Marines swiftly captured Hill 721 and 4th of July Hill, with a bold patrol securing Hill 767 to the northeast. On the left flank, while the 2nd Marines cleared Mutcho Point and Tanapag Harbor, the 6th and 8th Marines rapidly pushed to the coast, reaching the O-7 Line.
Watson's involvement in the offensive came to an end, with subsequent shifts in the axis of attack by the 27th Division and the 4th Marine Division towards the northeast.
Mindful of the significance of the day in American history and pleased with progress at Saipan, General Holland Smith distributed the following message to the landing force on the evening of July 4th: “The Commanding General takes pride on this INDEPENDENCE DAY in sending his best wishes to the fighting men on Saipan. Your unflagging gallantry and devotion to duty have been worthy of the highest praise of our country. It is fitting that on this 4th of July you should be extremely proud of your achievements. Your fight is no less important than that waged by our forefathers who gave us the liberty and freedom we have long enjoyed. Your deeds to maintain these principles will not be forgotten. To all hands a sincere well done. My confidence in your ability is unbounded.” The entire northern part of the island remained to be seized, including the important Marpi Point area; and this demanded a swing of the axis of attack to the northeast. Holland Smith, therefore, split the unconquered portion in half, assigning the left segment to the 27th Division and the right to the 4th Division. To allow sufficient time for the juggling of frontages and zones, the attack hour was delayed until noon of 5 July. Generals Griner and Schmidt, of the 27th and 4th Divisions respectively, were to "conduct such adjustment of their lines or make minor attacks prior to King-hour as they [deemed] necessary to launch a coordinated attack. . . ." The 4th Division's thrust had pushed well into the newly-assigned zone of the 27th Division, so that the previously described reliefs and shifts were necessary.
The Japanese forces remaining in the upper end of the island were poorly equipped, supplied, and often in poor health, yet they maintained high morale and a readiness to fight to the end. In the final push northward, Griner assumed control of the western front on June 25th. However, the advancement of his 105th and 165th Regiments was hindered by difficult terrain and strong resistance from fortified positions around Harakiri Gulch. On the right flank, the 24th and 25th Marines made successful progress to the O-8A Line after the 23rd Marines secured the intermediate O-7Z Line. Despite concerns of a potential Japanese counterattack during the night, accurate artillery fire dispersed enemy concentrations. The following day, Griner aimed to reach Makunsha by midday, but faced slow progress against obstacles like Harakiri Gulch and along the coastline. Consequently, Smith decided to adjust division boundaries, allowing Schmidt’s Marines to expand northwestward, envelop the 27th Division north of Makunsha, and assume responsibility for the entire front for the sweep to Marpi Point. Under this revised plan, the 27th Division resumed its assault in the afternoon, breaking through a coastal ditch but encountering resistance at the Gulch. Meanwhile, the 23rd Marines, on Schmidt's front, pushed northwest and northeast, with limited progress towards Makunsha. The 24th Marines gained approximately 1800 yards, and the 25th Marines secured Mount Petosukara, where 800 civilians surrendered.
Overnight, attempts to counterattack against Petosukara were swiftly thwarted, but significant action unfolded in the Makunsha region. For the 3rd Battalion, 24th Marines, stationed to protect the regiment's exposed left flank, the action was particularly vicious. Just before dawn the enemy rushed forward, armed with grenades and "idiot sticks," encouraging themselves with loud shouts and screams. Though this thrust failed to penetrate the Marines' lines, some of the enemy fell within five yards of the foremost foxholes. The action report of the 3d Battalion, 24th Marines, estimated the number of enemy killed in this attack at "more than 200."
On July 6, facing the complete breach of his last line of defense and with no options left, Saito realized the futility of the situation. With his forces depleted of essential supplies and under relentless artillery barrage, he issued orders for the remaining troops to execute gyokusai, a final suicidal assault aimed at inflicting maximum damage on the enemy. Several days prior to Saito's final order the assembly of remaining Japanese forces had begun. Some Japanese were out of reach behind U. S. lines, others were hidden in the deep shadows of caves, but all available were mustered. Marpi Point, Paradise Valley and Harakiri Gulch were sites for mobilization and reorganization. Many provisional units were formed in an effort to achieve some degree of tactical unity among the assorted groups and individuals. Weapons and equipment were wanting and some Japanese were armed only with grenades or crudely-fashioned spears. One Japanese staff officer, Major Kiyoshi Yoshida who participated in the battle estimated the total participants at 1,500, many with no weapons. In the light of subsequent events, however, his estimate appears too low. Assuming that he was misinformed on this point, it is not at all surprising; even at the assembly points, U. S. artillery and mortar fire hampered Japanese efforts to organize their troops and an accurate count was impossible. As the conglomerate force moved toward Makunsha, which would serve as a point of departure, it was subjected to persistent, heavy concentrations of artillery fire. This resulted in a limping approach with leaders calling upon every conceivable device to maintain the unity of their commands. Greater silence by the sprawling force would have helped; early in the evening patrols from the 27th Division Reconnaissance Troop had detected unusual activity. This had resulted in the large number of unobserved fire concentrations thrown into the Makunsha vicinity. By nightfall, Generals Saito and Igeta, along with Admiral Nagumo, performed seppuku after a final meal, while Colonel Suzuki Takuji gathered 3000 Japanese fighters, including naval and support personnel, unarmed civilians, and the injured, for a final desperate charge.
The blow fell at 4:45am. First and hardest struck were the isolated positions held by the 1st and 2nd Battalions, 105th Infantry. The attack on these units hit from front, flank and, after moving through the gap, the rear. Almost as soon as the attack was launched, communications to the rear were cut. It was then simply a matter of two isolated battalions of soldiers fighting for their lives. This they did and did well. Some of the soldiers stacked so many dead Japanese forward of their positions that it was necessary to move to get fields of fire. Major McCarthy, commanding the 2d Battalion, described the onslaught: “It reminded me of one of those old cattle stampede scenes of the movies. The camera is in a hole in the ground and you see the herd coming and then they leap up and over you and are gone. Only the Japs just kept coming and coming. I didn't think they'd ever stop.” The sheer weight of this attack, its ponderous momentum, carried it through the soldiers' lines. In addition, hundreds of Japanese moved past the isolated defense area, using the gap on the right. The fanatical surge then carried to the 3rd Battalion, 105th Infantry, located on the high ground overlooking Harakiri Gulch. Here the soldiers were on better defensive terrain; the Japanese had to climb up to them. The lines held, and the Japanese suffered staggering losses. This portion of the battle did not cease with the coming of daylight on 7th July but continued until midafternoon. Next to feel the impetus of the determined thrust was the 3d Battalion, 10th Marines, in firing positions about 500 yards southwest of Tanapag Village. The Japanese mass that struck this unit was apparently that portion of the banzai force which had moved through the gap between the 1st and 3rd Battalions, 105th Infantry. Hardest hit were Batteries H and Headquarters and Service, in position on the left of the railroad track. Batteries I and G, set up on the right of the track also got into the fight, although they were not as closely engaged as the other two. The only battery that actually fired its howitzers during the melee was H, the others being forced to remain silent by the presence of other artillerymen to their front. During the early phases of the battle, before Battery H was forced to abandon its firing positions, one of its howitzers was turned completely around to engage a Japanese medium tank which had ploughed through to the rear. At a range of less than 50 yards the artillerymen sent 105mm shells crashing into, and destroying, their armored target. Eventually, however, the pressure from Japanese infantrymen was too great; Battery H's outnumbered survivors pulled back. In the frantic confusion and haste of the retreat, they failed to remove the breech blocks or firing locks from the howitzers. The Japanese, oddly enough, neither used nor destroyed the weapons while they had control of the area. Battery I had been attacked at 0455, with Japanese advancing astride the railroad track. The first thrust was repulsed and the Japanese fell back to reorganize. A series of actions, followed this same pattern, continued until 0650, when all of the battery's small-arms ammunition was expended. At this time the battery commander, Captain John M. Allen ordered the firing locks removed from the howitzers and the unit to fall back to the positions of Battery G. Here the two batteries continued the fight until relieved by elements of the 106th Infantry later in the day. Located directly behind Battery H, headquarters and service personnel of the battalion were forced to retire after heavy, close-in fighting. Among the 136 casualties in the battalion was the commanding officer, Major William L. Crouch, who was killed. Japanese killed in the encounter numbered 322. Even as the Japanese surged directly against the 3rd Battalion, brother artillerymen of the 4th Battalion, 10th Marines, in position to the southeast, received pressure from the fringe of the main enemy tide. In defense of its firing positions, the battalion killed about 85 Japanese. Despite the turmoil of the banzai attack, the 4th Battalion responded on the morning of 7 July to an urgent request for support originated by the 23d Marines, fighting down the cliffs above Makunsha.
By 05:30, they had advanced further, reaching the command post of the 105th Regiment, where Bishop's hastily assembled American forces, aided by artillery, managed to repel the attack. Concurrently, secondary assaults were launched in Paradise Valley and Harakiri Gulch but were promptly quelled by American firepower. By midday, the banzai charge had been effectively halted, and the few surviving Japanese soldiers retreated to Mamushka, engaging in sporadic skirmishes with American troops throughout the day. Despite a counterattack by the 106th Regiment, they were forced to halt just 200 yards short of the Tanapag perimeter, and by midnight, the remaining American survivors were successfully evacuated.
During this engagement, the 105th incurred 406 fatalities and 512 injuries, while Marine artillery units sustained 45 deaths and 82 injuries. On July 8, at 04:30, the remaining Japanese forces launched another attack on the 106th's positions, only to be swiftly repelled. Against the coastal portion of this line the Japanese executed a vigorous thrust during the night of July 7th. Though the strength, organization and planning of this second attack were weak by comparison with the previous effort, the vigor and determination with which it was executed did not vary. Shortly after midnight a report came from the observation post atop Hill 767; Japanese force moving south. Enemy "feeler" patrols probing for weak spots were engaged as early as 3:00am, but the information that they took back to their commanders must not have been encouraging. No holes existed. The attack, launched about 4:30am, struck the 1st Battalion, 106th Infantry, along the beach. Grazing defensive fires swept across the flat beach like a scythe, cutting all in its path. The Japanese never seriously threatened penetration of the lines and those that attempted to swim around the flank were spotted and killed. Shortly after 7:00am the Japanese attack petered out and died. The 106th Infantry estimated that it had slaughtered about 1,000 of the enemy, while at the same time its own losses were practically negligible.
Watson's Marines then assumed control over most Army units and conducted cleanup operations for the ensuing two days. They discovered a total of 4,311 Japanese casualties, including those inflicted earlier by artillery and naval bombardment. Meanwhile, Schmidt's regiments, supported by the 2nd Marines, faced resistance as they advanced northeast and northwest. The NTLF Operation Order for 8 July instructed the 2d Marine Division, less detachments, to "advance in the present 27th Infantry Division zone of action, pass through elements of [that] division on its front line, attack, mop up and destroy enemy elements. . . . Upon passing through the 27th Infantry Division assume operational control 165th Infantry and 3d Battalion, 6th Marines, . . . assume tactical control within the assigned zone of action at 0630 [8 July]." Upon passage of its lines the 27th Division would revert to NTLF reserve. No effective resistance was offered the 2nd Marine Division after it had passed through the 27th Division on the morning of 8 July, although large numbers of poorly armed and totally disorganized enemy were encountered. Some Japanese used the familiar device of hiding in caves and firing from the deep shadows, but the bulk seemed eager to die and made headlong rushes at the Marines. This foolish expenditure simplified the mop-up. The 6th Marines' action report characterized the day's activities as an "attack . . . against a disorganized, swarming mass of Japs . . . waiting for the final death blow. . . ." Adding the hundreds found strewn through its zone to the number that it disposed of, the 6th Marines made a "conservative estimate" for 8 July of 1,500 dead Japanese in its area. On more rugged terrain inland the 8th Marines encountered much the same type of resistance. Here, with more caves to investigate, the sweep was somewhat slower. One wooded pocket encountered, a deep ravine, caused a minor delay. The tactic that previously had worked so well was again employed: one company stayed behind to contain and mop-up while the rest continued the push. The 8th Marines' zone, being inland of the main path of the banzai attack, contained fewer enemy bodies; but, even so, there was conclusive evidence that a terrific battle had taken place.With this final push, Turner declared the island secured, although General Jarman's garrison troops continued mop-up operations for several months.
Following the declaration that the island was secured, efforts to induce cave-occupants to surrender were intensified. Interpreters, using public address systems, pleaded with people in caves to come out. The device was not only attempted from land but from sea as well. LCI gunboats moved close inshore and broadcast promises of good treatment, for which they were answered with fire from Japanese soldiers in the caves. Even some of Saipan's leading citizens, who had surrendered and received good treatment, talked to those in the caves, urging them to yield. But, for the effort expended, the results were not encouraging. The primary reason for this failure was that the people had been saturated with Japanese propaganda to the effect that the Americans intended to torture and kill them. This had been repeated so often that the people came to believe it. At this time the very zenith of horror occurred. Hundreds of civilians, believing that the end had come, embarked on a ghastly exhibition of self-destruction. Casting their children ahead of them, or embracing them in death, parents flung themselves from the cliffs onto the jagged rocks below. The places they jumped from would become known as "Suicide Cliff" and "Banzai Cliff". Some waded into the surf to drown or employed other gruesome means of destroying themselves. How many civilians died in this orgy of mass hysteria is not known, but it is estimated that around 1000 committed suicide. A commander of a patrol craft (YP) said that the progress of his boat around Marpi Point at this time was slow and tedious because of the hundreds of corpses floating in the water.
On July 13, Colonel Riseley's 3rd Battalion executed the last Marine operation on Saipan, successfully assaulting Maniagassa Island, resulting in 14 Japanese deaths and the capture of 15 others. By the end of the battle, almost the entire Japanese garrison of approximately 28,000 personnel had been eliminated. About 1,700 were taken prisoner, including roughly half who were Korean laborers. Nearly 10,000 Saipan civilians, roughly 40% of the population, perished, with another 14,000 interned. American forces suffered approximately 16,500 casualties, comprising 3,100 fatalities and 13,000 wounded out of a total assault force of 71,000. This casualty rate, exceeding 20%, was comparable to Tarawa and marked the costliest battle for the Americans in the Pacific theater up to that point. That is all for today with Saipan as we now need to head over to New Guinea.
General MacArthur’s next offensive was to be the invasion of Noemfoor Island, codenamed Operation Cyclone. Noemfoor served as a crucial staging ground for Japanese forces destined to reinforce the Biak Detachment, owing mainly to its possession of two vital airfields. Despite being guarded by a modest contingent, primarily consisting of six infantry companies from Colonel Shimizu Suesada’s 219th Regiment, the Japanese presence on the island was scattered, rendering their defense disorganized. Allied estimates of Japanese strength on Noemfoor were too high, for there were not more than 2,000 Japanese on the island. Probably not more than 900 of these could be counted infantry effectives. In addition to the 2,000 Japanese, there were 600-odd Formosan laborers and approximately 500 Javanese slave laborers. The 3d Battalion, 219th Infantry, contained the bulk of the combat troops, but there were also present about 180 men of the 2d Battalion, 219th Infantry, and a like number of the 222d Infantry, 36th Division, troops which had been unable to reach Biak. The Japanese garrison on Noemfoor was commanded by a Colonel Shimizu, who was also the commanding officer of the 219th Infantry. Another unit, commanded by a Major Mori, but apparently under Colonel Shimizu's operational control, seems to have been a provisional organization containing mostly armed service personnel and numbering about 600 men.
General Krueger, anticipating minimal resistance, tasked Colonel Sandlin’s 158th Regiment with Operation Cyclone, overseen by General Patrick. The assault was to be facilitated by Admiral Fechteler’s Task Force 77, supported by cruisers under Admiral Berkey and aircraft from the 5th and 13th Air Forces, which had been conducting preparatory bombings on Noemfoor and enemy air bases in the Vogelkop Peninsula. Patrick's strategy involved landing on Yellow Beach, where the enemy's defenses were perceived to be strongest, aiming for swift American control over Noemfoor's airfields. In many essentials, the landing plans for Noemfoor were very similar to those used at Biak; but in one major essential the Noemfoor landing plan differed radically from that employed at Biak. At the latter island the HURRICANE Task Force had used a beach which, while within easy marching distance of the principal objectives and the main concentration of enemy troops, was relatively undefended. But at Noemfoor, the landing was to be made in the face of the enemy's strongest defenses, known to be located in the Kamiri Drome area. YELLOW Beach, as the landing area was designated, extended approximately 800 yards along the western end of the airfield, which was situated almost at the high water mark. The reef presented fewer hazards there than elsewhere, since it was somewhat narrower than at most other points along the island's coast. The relative narrowness of the reef at Kamiri would also permit LCIs, LCTs, LCMs and LSTs to approach to within 450 yards of the beach, which was believed to be firm at the airfield. Moreover, landing at YELLOW Beach had the advantage of placing the assault troops immediately on their objective, permitting a rapid seizure of Kamiri Drome before the Japanese could recover from the shock of the naval and air bombardments. Enemy forces on the island would be split, and those stationed at Namber and Kornasoren Dromes would be isolated. To minimize casualties during the assault, the landing plan required the most intense naval bombardment witnessed in the Southwest Pacific Area thus far. Additionally, Krueger kept the 503rd Parachute Regiment on standby at Hollandia for airdrop once a suitable landing zone was secured, with the 34th Regiment stationed at Biak in reserve.
With all preparations finalized by the end of June, Fectheler’s unit set off from Toem at 18:00 on June 30, reaching southeastern Biak around 17:40 the following day. Subsequently, the American forces sailed towards Noemfoor, commencing deployment off Yellow Beach by 05:00 on July 2. Prior to the landings, the island had endured significant bombardment from General Kenney’s aircraft the previous day, with additional air assaults conducted leading up to the arrival of the troops. As the soldiers readied for the shoreline assault, Berkey’s cruisers and Fechteler’s destroyers bombarded Yellow Beach and its surroundings for approximately 50 minutes. Immediately before the landing, air bombardment, like much of the naval gunfire, was directed against the low coral ridges and hills behind Kamiri Drome. It was believed that the most determined enemy opposition would come from positions in these ridges, and to neutralize these possible defenses the 33 B-24's, at approximately H minus 15 minutes, dropped 500-pound bombs along the ridge lines.
The intensity of the Allied air and naval bombardment effectively dispersed most of the Japanese forces from the beach or kept those remaining pinned down. With the cessation of bombing, the initial wave of troop-carrying LVT's approached the outer edge of the reef, supported by rocket fire from LCI gunboats. Encountering no resistance, Sandlin’s 1st and 2nd Battalions disembarked near a coral ledge overlooking Kamiri Drome. The American forces then commenced advancement in the west, east, and south directions to expand the beachhead, facing only minor resistance from caves approximately 500 yards from the eastern end of Kamiri Drome. Simultaneously, Sandlin’s 3rd Battalion landed and swiftly joined mop-up operations at the east end of the airstrip, enabling the 2nd Battalion to turn southward towards the Kamiri River without encountering opposition along the way.
By 4:00, the 158th had successfully secured a rectangular area approximately 3000 yards wide and around 800 yards deep, reaching south to the banks of the Kamiri River. Despite enemy mortar fire, unloading operations had progressed well, with over 7100 men, 500 vehicles, and 2250 tons of supplies successfully brought ashore by evening. American casualties for the day were limited to 3 killed, 19 wounded, and 2 injured, while the Japanese suffered 115 dead and 3 captured. In anticipation of potential Japanese resistance elsewhere, Patrick had requested reinforcements, leading Krueger to order Colonel George Jones’ 503rd Parachute Regiment to advance to Kamiri. On July 3 around 05:15, regimental headquarters and the 1st Battalion began loading onto 38 C-47s at Cyclops Drome, with plans for the other two battalions to drop over the following days. Launching was completed by 07:47, with successful arrival over Noemfoor at 10:00. The leading C-47's paratroopers were on the ground just ten minutes later.
The planes were to fly over Kamiri Drome in flights of two each, the first plane at a height of 400 feet and the second echeloned slightly to the right rear at 450 feet. Subsequent flights were to follow at a distance of 300 yards. Contrary to plans, the first two C-47s flew over the strip at a height of about 175 feet, and the next eight planes all flew below 400 feet. Dropping from this low altitude caused the paratroopers in the first ten C-47s to suffer many casualties; more casualties resulted because the planes flew over the strip two abreast. The broad formation caused many paratroopers to land off the southern edge of the 100-foot-wide runway in an area where Allied vehicles, bulldozers, supply dumps, and wrecked Japanese aircraft were located. Additional hazards beyond the cleared area were jagged tree stumps, trees partially destroyed by pre-assault air and naval bombardments, and a number of anti-aircraft gun emplacements. The drop resulted in 72 casualties among the 739 men dropped on July 3, including 31 severe fracture cases, many of whom would not be able to parachute again. Despite these challenges, Jones’s 1st Battalion took control of approximately 2000 yards in the center of the defenses around Kamiri Drome upon arrival, allowing Sandlin’s 2nd and 3rd Battalions to concentrate at the eastern end of the field and expand the perimeter. These battalions then proceeded eastward toward Kornasoren Drome, encountering well-prepared but unmanned defensive positions. Additionally, the 1st Battalion conducted patrols south of the Kamiri River but encountered only a few scattered enemy soldiers. The next day, Jones’ 3rd Battalion initiated their drop on Kamiri Drome. They encountered casualties, with 56 jump injuries among the 685 paratroopers who landed by 10:25. Given the significant injuries from both drops, Krueger and Patrick opted to transport his remaining battalion via water. They would arrive at Noemfoor by July 11. But for now, let's shift focus from Noemfoor to the Wakde-Sarmi area to discuss its final clean-up.
Following the main conflict's conclusion on June 25, General Sibert directed the 3rd Battalion, 1st Regiment and the 3rd Battalion, 63rd Regiment to clear Lone Tree Hill. By June 30, they successfully secured the area. On the same day, the 1st Battalion, 20th Regiment moved through the defile south of the hill and encountered only a few stragglers. Seeking to fully secure the Maffin Bay staging area, Sibert extended the perimeter to the Woske River on July 1 through the 1st Regiment's efforts. By July 4, elements of the 63rd occupied Hill 225, seizing the crest of Mount Saksin the following day. However, Hill 265, located southwest of Hill 225, presented greater challenges due to Japanese resistance and difficult terrain. Yet by July 9, the 1st Battalions of the 1st and 63rd Regiments secured the hill crest, previously held by elements of the 224th Regiment. With the capture of Hill 265, the last enemy stronghold in the Maffin Bay region fell. Meanwhile, General Tagami abandoned the idea of a decisive battle in the Woske sector, opting instead to withdraw the majority of his 36th Division toward Sarmi and Sawar, with remnants of the 224th Regiment assuming defense of Woske.

The fall of Saipan pierced the Japanese inner defensive perimeter, now the home islands were vulnerable to strategic bombing. The battle claimed nearly 50,000 casualties and at least 8000 civilian deaths. The intense percentage of casualties suffered by the Americans would have a profound effect on future American planning for the Pacific War.
