- 161 - Pacific War Podcast - Third Arakan Offensive - December 17 - 24 - , 1944

Last time we spoke about the invasion of Mindoro. Ormoc fell on December the 10th. The 149th Regiment cleared the airstrip at Buri, while the Japanese launched a desperate attack on airfields, only to be repelled by American forces. Amid chaotic battles, the Japanese attempted maritime reinforcements, but their vessels were met with devastating American fire, sinking transports and crippling their efforts. By December 13, the American advance continued through heavy resistance, leading to intense skirmishes, showcasing bravery and the struggles faced on both sides during the conflict. On December 14, US troops of the 2d Squadron, 7th Cavalry, advanced against stubborn Japanese defenses near Limon. While under fire, they strategically pushed forward, capturing enemy positions and equipment. Despite heavy artillery, Troop G utilized flamethrowers and close combat, overcoming formidable foxholes, helping to secure vital ground. Meanwhile, Admiral Nimitz prepared for future invasions, and General MacArthur postponed operations to protect his forces. The successful landings on Mindoro marked a pivotal moment, signaling the approaching assault on Luzon.

As we left off last week, General Bruce’s 77th Division had effectively advanced to Linao and Cogon, securing Ormoc. Meanwhile, General Sibert’s 10th Corps had pushed the weary Japanese forces in the north back to the Lonoy area, with both divisions preparing to continue their assaults through the Ormoc Valley toward Valencia, in line with General Krueger’s strategy. To address the emerging situation, the 68th Brigade was mobilizing to support the 1st Division, while the 5th and 77th Regiments were making their way to Huaton to participate in a counteroffensive against Ormoc; however, only the 77th Regiment would reach its destination in time. Concurrently, the isolated 16th Division in the central Leyte mountains was gradually withdrawing from the Burauen front, losing strength with each passing day, and the 26th Division was gathering north of Talisanyan to prepare for the final retreat to Ormoc. On December 16, with the port secured, Bruce’s forces were poised for the next stage of their advance north along the Ormoc corridor. Given that his patrols reported minimal enemy resistance west of Highway 2, Bruce aimed to encircle the Japanese forces from the east with the 306th and 307th Regiments, while the 305th would advance along the highway. Following this plan, the 305th Regiment quickly eliminated the remaining enemy positions in Cogon and proceeded 400 yards north of the road junction toward Tambuco. Meanwhile, the 307th swiftly moved through the neighborhoods of Jalubon, Liloan, Bao, and Catayom to San Jose, where they encountered and defeated two platoons of paratroopers. The 306th Regiment also advanced to Jalubon but then shifted north toward Tipic to bypass Huaton and directly assault Valencia.

Looking north, while the 126th and 127th Regiments fought bravely against an enemy that restricted the division's progress to just a few dozen yards each day, the 12th Cavalry Regiment continued its advance toward Lonoy. Ultimately, the successful American assault on December 16 left the Japanese defenses exposed, prompting General Suzuki to alter his offensive strategy once more, immediately directing his forces to conduct a delaying action to facilitate a final retreat toward Libongao. Meanwhile, Bruce intensified his attack on December 17. As a result, the 305th Regiment encountered stiff resistance while attempting to reach Tambuco. The Japanese had constructed defensive positions along Highway 2 in the southern part of Ormoc Valley. At the road junction of Highway 2 with the road to Liloan were many trenches three to four feet deep and parallel to the highway. Trenches had also been dug along the sides of a machine gun emplacement that occupied a slight elevation commanding Highway 2 both to the north and to the south. On both sides of the road from Cogon to Catayom foxholes lined Highway 2, in the ditches and under the shacks. Some of these positions were dug on a slant and were six to seven feet deep. At Tambuco the foxholes extended along the highway for 400 yards, with machine gun emplacements on the sides of the foxholes. Other positions along Highway 2 consisted of poorly integrated foxholes and machine guns that covered the road. The field artillery pieces between Tambuco and Catayom were placed along the highway, with the exception of a 75-mm. gun that guarded a bridge and was well concealed inside a roadside shack.

At 0830 on 17 December the 305th Infantry moved out along Highway 2. At 1000 the 1st Battalion reported that it was advancing at the rate of 100 yards every ten minutes against light opposition. By 1145 the 305th Infantry was fighting through Tambuco. At a road junction just north of Tambuco, it eliminated some enemy resistance and the advance slowed down. The regiment moved forward to a point about 300 yards north of the road junction and established its night perimeter, which extended 300 yards to the northeast along the Tambuco-Dolores road in order to forestall any Japanese counterattacks from that direction. On the same day the 306th Infantry pushed its attack northeast at 0800. The advancing troops almost immediately encountered Japanese who, apparently taken by surprise, were unable to offer organized resistance. At 1040, when the forward elements were 1,000 yards southwest of Cabulihan, the opposition stiffened and the regimental commander therefore committed the 3d Battalion on the left of the 2d Battalion. The advance continued. As the regiment neared Highway 2, resistance became more intense. The 306th Infantry encountered the Japanese who were fleeing northwest from the assault of the 305th Infantry and the heavy artillery that accompanied it. (Unknown to the Americans, General Suzuki and his staff were among the retreating Japanese. Suzuki succeeded in escaping to Libongao, where he established a new headquarters for the 35th Army.) At 1440 the 306th Infantry reached Highway 2 between Catayom and Cabulihan and proceeded north toward Cabulihan, its objective. Advance elements of the 3d Battalion reached the outskirts of the town but withdrew three or four hundred yards to take advantage of more commanding terrain. After combat patrols had cleared the area, the 306th Infantry established its night perimeter five hundred yards south of Cabulihan at 1600. 

General Bruce had ordered the 307th Infantry to remain in San Jose until further notice. Since the guerrilla forces had reported a large number of Japanese in the area, General Bruce had made arrangements to soften the sector with an aerial bombardment and artillery fire before the infantry attack. In response to Bruce's request, fifteen P-40's from the V Fighter Command had been made available by General Whitehead for an air strike against the Valencia area. The 155-mm. guns of the 226th Field Artillery Battalion at Daro began firing on Valencia and the airstrip on the morning of 17 December and hit a Japanese ammunition dump. At 1245 the artillery fire was halted for the air strike, and for fifty minutes the area was bombed and strafed. With the conclusion of the air attack, at 1335, the artillery began anew to pound the area. "The medium artillery . . . reached out from Ormoc and the 'Long Toms' . . . from Daro joined in the fighting." In the meantime the 902d Field Artillery Battalion moved forward to a point from which it could support the advance of the 307th Infantry. At 1415 the artillery fire stopped and the 307th Infantry moved out astride the San Jose-Valencia road toward Valencia. Though the artillery fire and aerial bombardment had driven some of the Japanese from the area, a strong well-equipped force, including a number of paratroopers, remained to oppose the 307th Infantry. The regiment pushed forward, however, and at 1640 its leading elements were on the southwestern edge of the airstrip and within 1,000 yards of Valencia. The 307th Infantry formed its night perimeter on the edge of the airfield and made preparations to continue the attack on 18 December.

During 17 December, despite the disorganization of the Japanese forces, Colonel Imahori of the 12th Independent Infantry Regiment tried to reach Ormoc, but he was unsuccessful. A few enemy artillery shells landed in the Ormoc area but that was all. General Bruce wrote later: "The men got a laugh because the General's latrine, unoccupied, was struck. He wished about that time that he had remained up front which he had reached by landing in a cub plane on an unimproved jungle road." The following morning, as supplies and ammunition for the 306th and 307th Regiments were running dangerously low, Bruce dispatched an armored column through the 305th’s lines, which bypassed enemy strongholds and successfully delivered supplies to both regiments. The 305th Regiment then faced minimal resistance as it advanced toward Huaton, with its 3rd Battalion decisively eliminating all enemy opposition along the Dolores road. Simultaneously, the 306th Regiment steadily pushed toward Valencia, successfully reaching the southern edge of the town, while the 307th secured the airstrip without any resistance.

As General Gill directed his forces northward, the 126th Regiment successfully seized a ridge east of the road, advancing closer to the main enemy defensive line located north of Lonoy. On the morning of December 19, the 126th launched another offensive, overrunning numerous enemy positions and advancing 200 yards before being replaced by fresh troops the following day. Meanwhile, the 12th Cavalry encountered only light and sporadic resistance in its efforts to secure Lonoy, although its 2nd Squadron faced tougher opposition while assaulting a knoll southeast of the barrio. To the south, following the fall of Valencia, the 5th Regiment reached Libongao just as Bruce prepared to press forward in the northern campaign. Thus, the 307th Regiment steadily advanced north along Highway 2, engaging an advanced battalion from the Takahashi Detachment, while the 306th moved successfully northwest across the terrain to a position 300 yards south of the Palompon road. On this day, Suzuki received news of the enemy's invasion of Mindoro, along with General Yamashita’s orders to conduct a strategic delay on Leyte. In response, he commanded all his forces to begin a gradual withdrawal towards Palompon, leaving Libongao for Matag-ob. On December 20, the 306th Regiment reached the Palompon road and dispatched its 1st Battalion west towards the Togbong River, while the 3rd Battalion turned east towards Highway 2. At the same time, the 307th Regiment launched an assault on the Libongao positions and successfully defeated the 5th Regiment, compelling the Takahashi Detachment to retreat towards Matag-ob, where they established Suzuki's final delaying position. Additionally, as the exhausted 126th Regiment was relieved, the 12th Cavalry began moving south from Lonoy to intercept the enemy's retreat route at Kananga.

On December 21, as the 1st and 102nd Divisions began their withdrawal towards Palompon, the 12th Cavalry successfully captured Kananga and established contact with patrols from the 77th Division. Consequently, Highway 2 was finally open from Ormoc to Pinamopoan, and the Ormoc Valley, where the Japanese had fiercely resisted the American advance, was now firmly under the control of the 6th Army. General Mudge, commanding general of the 1st Cavalry Division, said of the 12th Cavalry: “As a result of the stout-hearted efforts of the 12th Cavalry Regiment, elements of the Division are within 2500 yards of making contact with forward elements of the 77th Division. Considering the fact that the regiment has been reduced to 50% strength by the rigors and deprivations of 40 days in the mountains, the display of courage, stamina, and drive on the part of the 12th Cavalry is a credit to the best traditions of the United States Cavalry.” However, we must now shift our focus from the Philippines to Burma to follow the progress of Operation Capital. 

Previously, while General Sultan’s offensive in the north was advancing well, General Slim’s eastern push, led by General Rees’ 19th Indian Division, encountered less resistance than anticipated. This indicated that the enemy was rapidly retreating to stronger defensive positions behind the Irrawaddy River. As a result, Slim’s strategy to encircle General Katamura’s 15th Army on the Shwebo Plain was compromised, necessitating a significant adjustment to his offensive. His forces, stretched from Tamu, were at risk of counterattack while attempting to cross one of the most formidable river barriers. Therefore, Slim aimed to find a way to not only cross his troops over the Irrawaddy without major issues or interference but also to gain the decisive advantage needed to engage the Japanese on his terms, targeting them where their defenses were weakest.

In just a few days, Slim and his team devised a new strategy known as Operation Extended Capital. The objective was to convince the Japanese that nothing had altered and that the 14th Army's advance was still primarily directed toward Mandalay, with its two corps crossing the Irrawaddy to the northwest of the city. The core of Slim's revised plan involved General Stopford's 33rd Corps, which, bolstered by the 19th Division and the 268th Tank Brigade, would maintain its planned crossing of the Irrawaddy north of Mandalay. Meanwhile, General Messervy's restructured 4th Corps would tactically cross the river much farther south in Pakokku, allowing them to launch attacks on Meiktila and Thazi, crucial points along General Kimura’s communication lines that supported both the 33rd and 15th Armies.

The towns of Meiktila and Thazi represented ground that was vital to the enemy defense, a concept 14th Army had first learned painfully in Arakan. The railway and main road from Rangoon ran through Meiktila before bending north on their way to Mandalay, and the town formed a natural location for supply and ammunition dumps, airfields and hospitals. If Slim could cut off both Honda and Katamura’s corps from this vital logistical center, the Japanese ability to resist General Stopford’s inexorable pressure in the north around Mandalay would be fatally weakened. Slim recognized that without Meiktila, Kimura could not hope to sustain a prolonged battle for Mandalay. Indeed, it might even prove to be the decisive act in the destruction of the whole of Kimura’s army. Thus, the northern advance by 33rd Corps would be a deception to hide the decisive strike by 4th Corps to the south. If Slim could attract the greatest possible number of enemy divisions towards the northern crossing points (where, after all, Kimura expected him to strike), he could minimize opposition to the real focus of his attack in the south. This would provide Slim with, as he put it, ‘not only the major battle I desired, but the chance to repeat our old hammer and anvil tactics: 33rd Corps the hammer from the north against the anvil of 4th Corps at Meiktila – and the Japanese between.’

Simultaneously, a new offensive was gearing up in the south. Unable to execute Operation Dracula, an intended amphibious assault on Rangoon, Admiral Mountbatten was resolved to initiate an offensive in the Arakan region. Codenamed Operation Romulus, it aimed for General Christison's 15th Corps to again attack Akyab, marking the third attempt to regain Arakan since the war began. Christison's strategy involved a three-pronged attack into northern Arakan, with Major-General George Wood’s 25th Indian Division advancing on the right along the coast, Major-General George Bruce’s 82nd West African Division in the center within the valley of the Mayu river, and Major-General Frederick Loftus-Tottenham’s 81st West African Division on the left in the Kaladan river valley. Expecting heightened Japanese resistance along the Donbaik-Rathedaung-Myohaung line, Christison suggested that while his three frontline divisions engaged the Japanese forces with aggressive attacks, Brigadier Peter Young’s 3rd Commando Brigade would land in the Japanese rear on the Myebon peninsula, followed closely by Major-General Cyril Lomax’s 26th Indian Division, in a bid to finally capture Akyab.

Facing them was General Sakurai’s 28th Army, which included the Sakura Detachment, organized around three infantry battalions from the 55th Division along with the 55th Reconnaissance Regiment, stationed along the Godusara-Buthidaung-Kindaung line and the Kaladan Valley. Lieutenant-General Miyazaki Shigesaburo’s 54th Division was responsible for defending the remainder of the Mayu Peninsula and the coastal area extending to Taungup. Meanwhile, Lieutenant-General Sakuma Ryozo’s diminished 55th Division occupied the Irrawaddy Delta region, and Major-General Yamamoto Tsunoru’s 72nd Independent Mixed Brigade was positioned near the oilfields at Yenangyaung. Additionally, the Katsu Force, centered around the 153rd Regiment, was near Yenangyaung, while the Rangoon Defense Unit, which included the Rangoon Anti-Aircraft Unit and various logistical elements, was tasked with protecting Burma’s primary port. Sakurai’s strategy, known as Operation Kan, entailed a defensive stance on the Mayu Peninsula and Yenangyaung, along with safeguarding the southwestern coast near Bassein against potential amphibious assaults. As the defenders slowed the enemy's progress towards their fortified positions, the 54th Division would be promptly sent to launch a counteroffensive. Depending on the nature of the attack, units from the 55th Division and Katsu Force would also participate in this counterattack. If a significant battle erupted near Rangoon, the reserve 2nd and 49th Divisions would be deployed without delay. Meanwhile, with the 26th Division being withdrawn for rest, the 25th Division preparing to move towards Rathedaung, and the 82nd Division advancing into the Kalapanzin Valley, the 81st Division was dispatched on October 1 to progress through the Mowdok Mountain Range toward Kyauktaw.

As they moved southward across challenging and nearly impassable terrain, the West Africans expected to capture Mowdok by October 18, effectively eliminating the last Japanese forces from Indian territory before progressing through the Kaladan Valley. The 55th Reconnaissance Regiment stationed at Paletwa endured multiple assaults until early November, at which point they received orders to retreat to the Kaladan line. On December 15 the Japanese launched a strong attack with artillery support against the 6th (West African) Brigade. Private Kweku Pong, number two on a Bren, was wounded and separated from his section. Well armed with 12 magazines, he engaged the Japanese with short bursts for hours as they searched for him, until he eventually lost consciousness from loss of blood. Havildar Umrao Singh’s gun section of the 30th Mountain Regiment was supporting the brigade when it was overrun and his officer badly wounded. With two other men he defended the position with rifles, bayonets and grenades until they were rushed and he defended it by swinging a rammer until borne down and bayoneted. The Japanese were eventually driven off when both men were found; Singh was awarded a VC and Pong an MM. Slim never changed his view that Africans would be ‘lost’ without British guidance; but he probably never heard of Kweku Pong, who found himself alone, badly wounded in the middle of the night with Japanese rampaging through the bush around him and a battle going on behind. No white man was there to tell him what to do, no African NCO nor any other African for that matter. Nobody would have blamed him for lying doggo, but instead he showed considerable courage and good tactical sense. For this action, the 5th Gold Coast Regiment was awarded the unique honor ‘Tinma’. 

Meanwhile, by late November, Wood had sent the 51st Indian Brigade to assist the African offensive in the Kalapanzin Valley. After successfully completing this mission, the 25th and 82nd Divisions launched their assault on Buthidaung on December 12. Wood’s strategy involved a series of coordinated moves, with units leapfrogging one another, while the pace of the advance depended on how fast the sappers could repair the routes for the subsequent vehicles. Significantly outnumbered, Major-General Sakurai Tokutaro’s troops were ultimately forced to evacuate Buthidaung on December 14. In response to the escalating enemy pressure in both the Kaladan and Mayu regions, the 28th Army ordered the Matsu Detachment, consisting of three battalions from the 54th Division, to take over control of the Kaladan front, while Major-General Koba Tomotoki's forces advanced toward Tinma. However, Loftus-Tottenham wisely decided to outflank this position, compelling the recently arrived detachment to withdraw, while other African units successfully made their way to Kyauktaw by the month’s end. At the same time, the 53rd Indian Brigade progressed along the Kalapanzin River, and the 82nd Division managed to overcome strong resistance at Kindaung village in late December.

On the night of December 21, the 6th Oxfordshire and Buckinghamshire Light Regiment undertook a night march exceeding 20 miles to capture Donbaik, which was taken without resistance. It was only at this point that the remains of the Valentine tanks and crews lost two years prior were discovered. The Sakura Detachment, having reached its limit, had no option but to retreat towards Myohaung, where they would be supported by the Matsu Detachment during their final withdrawal to Prome. With no opposition encountered, the two West African divisions successfully made contact on January 4, resulting in the complete clearance of the Kalapanzin valley. Meanwhile, looking north, Slim had initiated Operation Extended Capital on December 19. In line with this, Stopford instructed the 19th Division to advance along the west bank of the Irrawaddy to launch an attack on Shwebo from the east, while the 2nd British Division, having crossed the Chindwin at Kalewa, approached Shwebo from the west. After capturing Shwebo, the 19th Division was to pivot eastward to secure bridgeheads across the Irrawaddy north of Mandalay, while the 2nd Division continued south towards the Irrawaddy bend near Sagaing. Slim aimed to create the impression that the entire 14th Army was advancing on Mandalay by associating the 19th Division with the 4th Corps. Additionally, the 20th Indian Division was tasked with crossing the Chindwin at Kalewa and moving downstream to capture Monywa. Meanwhile, Messervy was organizing his dispersed divisions to commence their advance down the Gangaw valley, from Tamu to Pakokku.

In the lead would be the Lushai Brigade and the 28th East African Brigade, tasked with clearing the enemy from Gangaw and subsequently advancing to Pakokku. The tour de force of deceptions against the Japanese would aid the crossing of the Irrawaddy. Slim’s intention behind the plan, known as Cloak, was to conceal the main crossing until the last possible moment by persuading the Japanese to believe that the force preparing to move down the Gangaw valley to cross the river near Pakokku and seize Meiktila was merely making a feint to distract attention from the attack on Mandalay by 33rd Corps from the north. Until now 14th Army’s commanders had been reluctant to use any but the simplest signals deceptions, but now they were enthusiastic even to the detriment of operational communications. Thus, three schemes were adopted: Pippin, which covered the withdrawal of the 5th Indian and 11th East African Divisions; Stencil, which created a dummy 4th Corps Headquarters that appeared to control formations under 33rd Corps; and Cloak, which was designed to give a false impression of the forces operating – that the forcing of the Irrawaddy would take place away from the real main effort, and that any movement the Japanese saw in the Gangaw valley was itself only a diversion. There is no doubt the speed the advance into central Burma achieved was in no small measure due to this deception scheme, which also used political channels, displays and deception devices dropped by Mosquitos and Beaufighters.

Following them, the 7th Indian Division aimed to capture Pakokku, secure the west bank of the Irrawaddy, and establish a bridgehead across the river. Once this bridgehead was established, the 17th Indian Division and the 255th Tank Brigade would cross the Irrawaddy and race towards Meiktila. However, before initiating this advance, Messervy needed to enhance the pathway through the valley to facilitate the movement of his artillery and armored units. The Lushai Brigade, already forward, also needed artillery support before launching their assault on Gangaw. Therefore, while Messervy’s engineers promptly began upgrading the road and track south of Kalemyo, only Stopford’s units would engage in combat in late December. Moving swiftly, the advance elements of the 2nd Division, along with the tanks from the 254th Brigade, passed through Pyingaing on December 23 and continued towards Paga, successfully overcoming several rearguard positions held by elements of the retreating 33rd Division, which eventually reached Monywa in early January. At the same time, the 19th Division captured Wuntho and began its advance southward towards Shwebo.

In the meantime, Messervy’s engineers worked diligently for two weeks to prepare the track, and by the end of the month, his field artillery was en route to Gangaw. The 28th East African Brigade departed Imphal on December 22, followed by the 7th Division four days later. However, in the northeast, Sultan continued his northern offensive with minimal success. With the Ledo Road now extended from Kamaing to connect with the Myitkyina-Bhamo road, the 112th and 113th Chinese Regiments received orders to eliminate the Japanese rear guards along the final segment of the road to China. In the period between the split of the CBI Theater in October 1944 and the fall of Bhamo on 15 December, the Ledo Road engineers under General Pick brought the survey of the Ledo Road from a point just below and east of Kamaing, 211 miles from Ledo, to a juncture with the Myitkyina-Bhamo road. The Ledo Road was to bypass Myitkyina, for there was no point to running heavy traffic through an inhabited place, and Myitkyina's supply needs could be served by an access road. Metaling and grading were complete almost to Mogaung. The Mogaung River had been bridged near Kamaing, and a temporary bridge placed across the Irrawaddy. Tonnage carried on the road for use within Burma was steadily rising. In early October it had carried 275 tons a day; by the latter part of the month the rate was twice that. Immediately after Bhamo's capture, the advance headquarters of the road engineers was moved to that town. A combat supply road was made from Mogaung, below Myitkyina, to a point just ten miles west of Namhkam.

The 113th Regiment advanced up the valley along the established road from Panghkam, while the 112th proceeded through the hills. The primary assault was to be led by the 30th Chinese Division, with its 90th Regiment advancing straight along the road toward Namhkam, while the 88th and 89th Regiments executed a shallow envelopment to the south of the road. Although conditions were favorable for a rapid advance into the Shweli valley, the commander of the 90th Regiment hesitated, causing delays along the flanks, as they formed the center of the Chinese line. Concurrently, Sultan ordered the Mars Task Force to embark on a challenging march through the hill country to the Mong Wi area, aiming to cut off the Burma Road near Hosi and effectively encircle the enemy 33rd Army. The 50th Chinese Division, which had been following the 36th British Division down the Railway Corridor, was set to occupy the vacated positions at Tonkwa and Si-u. Its objective was to cross the Shweli near Molo and proceed southeast to capture Lashio.

Amidst fierce battles, General Bruce's troops advanced against Japanese forces in Leyte, securing key positions and paving the way for further assaults amid strategic retreats. In a strategic deception, Slim's forces advanced on multiple fronts, aiming to outmaneuver the Japanese, ultimately leading to decisive victories in Burma and weakening enemy defenses.
