- 166 - Pacific War Podcast - the Mandalay Offensive - January 21 - 28 , 1945

Last time we spoke about the South China Sea Raid. In January, General Krueger reinforced the American beachhead at Lingayen Gulf while Admiral Halsey launched Operation Gratitude, targeting enemy ships based on faulty intelligence. Despite not finding the expected battleships, American forces decimated a Japanese convoy, sinking numerous vessels and claiming 113 enemy aircraft. Meanwhile, on Luzon, the 1st and 14th Corps advanced against Japanese defenses, capturing key positions despite fierce resistance. As both sides prepared for counteroffensives, the battle intensified, marking a pivotal moment in the Philippines campaign. On January 17, the 58th Brigade and supporting regiments launched a daring operation to destroy enemy positions. As American forces advanced, they faced fierce resistance, but some regiments achieved notable successes. Task Force 38 executed airstrikes on Formosa and Hong Kong, inflicting damage despite heavy losses. Meanwhile, Japanese forces struggled to regroup amid American pressure. General Suzuki devised a plan to fortify Leyte, but ongoing air raids hampered supply efforts. Tensions escalated as both sides prepared for decisive confrontations in the ongoing battle for control.

We last left off with, General Krueger strategically positioned General Mullins’ 25th Division on the right flank of the 43rd Division to bolster the assault forces at the Rosario front. This maneuver was also intended to facilitate the continuation of the 14th Corps’ advance to the south. Following the successful repulsion of General Nishiyama’s local counterattack, General Wing ordered the 63rd, 158th, and 172nd Regiments, which had been stalled, to launch an offensive from the west along the Damortis-Rosario road. Simultaneously, the 103rd and 169th Regiments were tasked with advancing northward along Route 3, originating from Pozorrubio. In contrast, while the 58th Independent Mixed Brigade and the 23rd Division worked to contain General Swift’s 1st Corps, General Yamashita was reinforcing the San Jose sector. He further instructed the Shigemi Detachment to maintain a defensive position in Binalonan. Although the 27th and 161st Regiments had successfully relieved the 103rd Regiment in the Binalonan area, Major-General Shigemi Isao ultimately opted to halt further troop movements. He decided to leave only a small garrison in Binalonan while the majority of his forces prepared for a decisive stand at San Manuel.

 

As the situation unfolded, the 3rd Battalion of the 161st Regiment encountered minimal resistance, allowing them to advance into the northern half of Binalonan by nightfall on January 17. In a parallel effort, General Patrick directed the 1st Regiment towards Urdaneta, where they successfully eliminated a small outpost belonging to the Shigemi Detachment. Additionally, he dispatched the 20th Regiment to the Cabaruan Hills, where they achieved their objective by reaching Lunec and securing the central area of the hills by the end of the day. On January 18, the offensive momentum of the 6th and 25th Divisions persisted. The 20th Regiment advanced to a low ridge approximately 2,500 yards west of Cabaruan, where American forces identified the primary defenses of the 2nd Battalion, 71st Regiment. Meanwhile, the 161st Regiment successfully cleared Binalonan, and the 27th Regiment moved forward to seize control of the Bactad area, further consolidating their gains in the region.

Simultaneously, Wing's units were gearing up for a significant new offensive. In line with this strategy, the 2nd Battalion of the 169th Regiment advanced along Route 3, deftly circumventing the town of Sison, and finally reached a crucial road junction located to the northeast of the town. Meanwhile, to the north, the 172nd Regiment executed a successful nighttime ambush against a Japanese artillery battalion. Following this victory, they dispatched a company to seize control of a strategically important hill, rising 600 feet and situated approximately 1,000 yards north of Rosario. This position enabled American forces to exert control over a substantial portion of the surrounding area. By the conclusion of the day, the 158th and 63rd Regiments established contact through patrols about a mile south of Amlang, as they prepared for a coordinated assault that was set to launch on January 19. This offensive culminated in the collapse of the last Japanese defenses just two days later. Concurrently, the 172nd Regiment successfully established a patrol base on Hill 606. From this vantage point, patrols ventured into Rosario, discovering the town was heavily mined, riddled with booby traps, and defended by concealed machine-gunners and riflemen hiding amidst the rubble of the buildings.

On January 19, the 103rd Regiment initiated an assault on Hill 600, located at the southern end of the ridge line east of Route 3. At the same time, the 2nd Battalion of the 169th Regiment faced several intense counterattacks from retreating Japanese forces that had been bypassed at Mount Alava and Sison. Despite the fierce resistance, the relentless pressure from Japanese troops and increasingly heavy artillery fire ultimately compelled the battalion to withdraw by noon. Nevertheless, the American operations succeeded in diminishing the Japanese presence in the region. Looking southward, the 161st Regiment cautiously advanced toward San Manuel, while the 27th Regiment effectively moved into Asingan, successfully cutting off Shigemi’s escape route. Further south, the 1st Regiment rapidly progressed along Route 3 toward the Agno River, capturing the towns of Villasis, Carmen, and Rosales. Meanwhile, the 20th Regiment commenced an assault on the 2nd Battalion of the 71st Regiment stationed in the Cabaruan Hills.

On the front commanded by General Griswold, the 14th Corps was in the process of mobilizing along the Camiling-Anao line, preparing to initiate an advance toward the Tarlac-Victoria line. The 160th Regiment began its march, covering seven miles southward from Camiling along Route 13, while the 129th Regiment took a strong position in Anao, establishing vital contact with other outposts of the 37th Division stationed at Paniqui. The advances made on January 20 were notably swift, with the 148th Regiment successfully capturing the towns of Gerona and Pura. Meanwhile, the 37th Reconnaissance Troop made significant progress by entering the guerrilla-occupied area of Victoria, and units from the 40th Division advanced to within four miles of Tarlac, signaling a promising push toward their objectives.

In the area around Cabaruan, the Japanese forces had sustained heavy losses during the initial attack. In response, Colonel Patrick made the strategic decision to withdraw two battalions from the hills to reinforce the southern advance. Probing slowly through the roughest ground in the Cabaruan Hills on January 20 and 21, the 20th Regiment's reinforced battalion jumped off in the morning of the 22nd in what was expected to be the last attack, its way paved by an especially heavy artillery and air bombardment. But from the start, operations did not go as planned. The air strike, conducted by Fifth Air Force A-20s was four hours late, subjecting the infantry to "a nerve racking wait," and did not include requested napalm. Air and artillery concentrations were, however, well placed, and it seemed improbable to the waiting infantry that many Japanese could have lived through them. A combined tank-infantry assault began about 12:30 and proceeded slowly but steadily for almost two hours. Then the attackers were stopped cold by a tremendous burst of rifle, machine-gun, and light artillery fire from the very hillsides that had received the weight of the bombardments. Company E, in the lead, fell back; Company G's officers were all either killed or wounded, and the company was temporarily scattered; Company F was pinned in place; and two supporting tanks were knocked out. Casualties mounted quickly to 10 men killed and 35 wounded.

As a consequence, Patrick found it necessary to redirect one battalion from the 1st Regiment to support the ongoing attack. Simultaneously, the remainder of the 20th Regiment pressed forward toward Cuyapo, while the bulk of the 1st Regiment continued its eastward movement toward the guerrilla-held Balungao. Additionally, the 6th Reconnaissance Troop reached Guimba, successfully establishing contact with patrols from the 14th Corps, which was crucial for coordinating their efforts. On another front, with Mount Alava now vulnerable, the 169th Regiment launched a vigorous assault on January 20, managing to secure the summit of the mountain by nightfall. In contrast, the 103rd Regiment continued to face heavy casualties during their frontal assaults against Hill 600, ultimately gaining only a precarious foothold on the exposed southern slopes. Meanwhile, in a significant naval development, Admiral Halsey’s Task Force 38 exited the South China Sea through the Balintang Channel on January 20. The task force was poised to execute further strikes against Formosa, aiming to disrupt enemy operations and bolster the Allied offensive in the region.

The following day, with significantly improved weather conditions, Admiral McCain’s aircraft carriers launched a coordinated series of airstrikes targeting Formosa, the Pescadores Islands, and the southern Ryukyu Islands. These operations resulted in the destruction of 104 Japanese aircraft on the ground, the sinking of seven oil tankers, and the loss of seven transport ships, along with additional damage inflicted on another seven vessels. 

For the first time since November 1944, TF 38 felt the sting of kamikazes. Operating just 100nm east of Formosa, TF 38 was not difficult to find. Just after noon, a single aircraft appeared to conduct a conventional bombing attack on TG 38.3’s light carrier Langley. One bomb hit forward. Personnel casualties were light, but the carrier was conducting flight operations three hours later. Within minutes, another aircraft also evaded radar detection and the CAP to commence a suicide dive against Ticonderoga. The kamikaze struck the flight deck and penetrated where its bomb exploded. An impending strike was spotted and ready to launch; now these aircraft provided fuel for the fire which was quickly spreading. Just before 1300hrs, another group of eight kamikazes and five escorts resumed the attack on TG 38.3. Only two suicide aircraft survived the CAP to dive on the wounded Ticonderoga. One was sent spinning into the water by antiaircraft fire, but the final attacker crashed into the carrier’s island. More fires were started. The crew succeeded in putting out the flames by 1415hrs and correcting a nine-degree list by 1800hrs. Though the ship was saved, the cost was high. Some 143 men were killed and 202, including her captain, were wounded. In addition, the air group lost 36 aircraft. As a final farewell, kamikazes attacked the two destroyers on picket duty just 65nm off Formosa at 1310hrs. A single Zero had joined a returning strike. Before it could be identified as enemy, it dove on destroyer Maddox, striking her amidships. This and the explosion of the bomb aboard created a fire that was quickly extinguished. After a final day of strikes on January 22 against the Ryukyus, during which eight ships were sunk, Task Force 38 set course for Ulithi. Upon arrival, Admiral Halsey transferred command of the Fast Carrier Force to Admiral Spruance, who would lead the final offensives in the Central Pacific. 

Meanwhile, back on Luzon, on January 21, the 160th Regiment swiftly cleared the town of Tarlac and began its advance toward San Miguel. Simultaneously, the 145th and 148th Regiments moved unopposed toward La Paz. The speed of 14th Corps' advance had stretched Griswold’s supply lines abnormally and had exposed his left from Cuyapo to La Paz, a distance of nearly 25 miles. He had no definite information about suspected Japanese concentrations in the vicinity of Cabanatuan, on Route 5 just 15 miles east of La Paz. His worries about the security of his flank were hardly put to rest by reports of new contacts with Japanese forces at Moncada, now 20 miles behind the front, and at La Paz. Elements of the 129th and 145th Regiments easily took care of the Japanese in the Moncada area; but during the night of January 21, a pitched battle developed at La Paz when a platoon of Japanese infantry, supported by one tank, attacked a 148th Regiment perimeter at a road junction a mile west of town. The Japanese finally withdrew after destroying a bridge that carried a secondary road across a river a mile east of La Paz; but because of this, Griswold reported to General Krueger that it would be impossible to extend 14th Corps' left any further south until he had more information about Japanese forces east of La Paz. To mitigate this risk, he decided to keep General Beightler’s 37th Division positioned in reserve while General Brush’s 40th Division continued its advance southward along Route 3 toward Bamban.

As a result, elements of the 160th Regiment and the 40th Reconnaissance Troop reached Capas and conducted patrols toward Camp O'Donnell on January 22. Meanwhile, the 161st Regiment began probing the defenses established by Japanese forces under Shigemi. The 103rd Regiment faced severe losses during their assault on Hill 600, necessitating a withdrawal to reorganize. Concurrently, the 169th Regiment launched an attack on Hill 355, making slow and costly progress against fierce resistance on the steep, barren slopes. By January 24, most of Hill 355 had been cleared, allowing the 3rd Battalion of the 103rd Regiment to move in and conduct mop-up operations in the area.

As the 158th Regiment looked northward and secured the area around Amlang, they initiated an eastward push towards the positions held by the 172nd Regiment. However, their advance was slow, with only a modest gain of 500 yards achieved. Over the next two days, the 158th faced a grueling battle, making painstaking progress as they advanced foot by foot across exposed hills and ridges, all while enduring relentless machine-gun, mortar, and artillery fire. It wasn't until January 26 that they successfully broke through to Cataguintingan, where they provided much-needed support to the 172nd Regiment's ongoing assaults into Rosario. Meanwhile, by the evening of January 23, the 161st Regiment had managed to secure the southern slopes of the barren ridge north of San Manuel. They established trail blocks in the Aboredo Valley, effectively controlling movement in the area. To the south, the 108th Regiment had taken control of the Capas region, while the 160th Regiment successfully captured Bamban. However, it became increasingly evident that the American forces were now confronting the well-fortified and organized defenses of the Kembu Group.

The Kembu Group's strength lay in the terrain it held, in the depth of its defenses, and in the great number of automatic weapons (aircraft and anti-aircraft) it possessed. Its major weaknesses were its immobility; the inadequate training and armament of the bulk of its troops; shortages of food, ammunition, and field artillery; and the rudimentary state of many defensive installations, a state deriving from the late start in establishing the positions at and west of Clark Field. The health of the command was poor from the start, and medical supplies were short. Morale was not of the highest order, and many of the troops were easily disaffected Formosan, Okinawan, and Korean labor personnel. In brief, the Kembu Group was the poorest armed, prepared, and supplied of Yamashita's three defense commands. On the other hand, as the 40th Division was soon to learn, even poor service troops, whatever their state of training and armament, can put up stiff resistance in good defensive terrain. 

In preparation for the defense of Clark Field, General Tsukada assembled a diverse array of forces, totaling approximately 30,000 troops, although the majority consisted of air and naval personnel. He strategically divided his Army units into four distinct detachments. The Takayama, Takaya, and Eguchi Detachments were positioned along the first and second lines of defense, facing eastward toward Highway 3. Their defensive line extended from the hills west of Bamban to the vicinity of Fort Stotsenburg. In contrast, the Yanagimoto Detachment maintained its mobile units at Angeles and Porac, ready to respond to any potential enemy paratrooper landings on the southern flank of the Clark Field defenses.

Additionally, Rear-Admiral Sugimoto Ushie commanded naval units comprising about 15,000 men, tasked with defending positions behind the two forward lines. In light of this formidable opposition, General Griswold made the strategic decision to utilize January 24 for consolidation and regrouping. This involved preparing for further advances southward while also probing into the enemy defenses that had already been uncovered. The 160th Regiment was able to secure Lafe Hill, although they were unable to establish a foothold on Hill 500, highlighting the challenges that lay ahead. To the north, American forces initiated another offensive against the Cabaruan Hills. The units of the 1st Regiment made only modest progress, yet they managed to advance closer to the main defensive positions as night fell. Meanwhile, at San Manuel, the 161st Regiment launched its first assault against the Shigemi Detachment, which encountered unexpectedly fierce resistance. As a result, the Americans were only able to establish a fragile foothold in the northern section of the town.

Further north, Wing directed the 103rd Regiment to set up a line of departure along Route 3, aiming to strike eastward at the northwestern slopes of Hill 600. At the same time, they were tasked with advancing up the southwestern slopes of the exposed Hill 700 to secure that strategic location, as well as Hill 800 to the northwest. The 169th Regiment, advancing to the left of the 103rd, was assigned to capture Question Mark Hill. Concurrently, the 63rd and 172nd Regiments were ordered to launch simultaneous assaults on Hills 900 and 1500, respectively, while the reserve 3rd Battalion of the 63rd Regiment was also committed to clear Benchmark Hill. This coordinated attack was scheduled for January 25. The initial phases of the assault showed promise, with the supporting forces making significant headway. However, the 103rd Regiment faced considerable difficulties, managing to secure Hill 800 only by nightfall. Notably, the 172nd Regiment achieved tactical surprise, successfully clearing most of Hill 900. Over the next two days, the 63rd Regiment regrouped around Hill 1500 in preparation for its own offensive.

Simultaneously, the 161st Regiment continued its slow advance southward through San Manuel, facing intense opposition. Patrick's units on the Cabaruan Hills managed to gain a mere 300 yards against determined resistance. Meanwhile, Brush pressed his attack on Clark Field, with the 160th Regiment clearing Hill 500 and advancing nearly a mile along the ridge from Lafe Hill, while the 108th Regiment secured Hills E and G. The following day, the 40th Division continued its southward maneuver. Any movement by American troops along the generally open ridges west of Route 3 inevitably brought down Japanese machine-gun and mortar fire, often augmented by fire from the dismounted aircraft automatic weapons, anti-aircraft guns, and light artillery. Seeking cover and usually pinned in place, the American infantry would call for close-in mortar and artillery support, wait for the concentrations to be fired, and then drive forward a few yards, when the process had to be repeated. Each time, the Americans managed to overrun a few Japanese machine-gun or rifle strongpoints. There was little choice of routes of advance. Draws, providing some concealment in scrub growth or bamboo thickets, were usually covered by well-emplaced Japanese weapons both within the draws and on the ridges to each side. Possession of the high ground, as ever, was essential. Yet the troops had to employ draws whenever possible to outflank Japanese ridgeline strongpoints, and often draws and ravines proved to be the only routes by which tanks, tank destroyers, and cannon company self-propelled mounts could get to the front to fire against Japanese cave positions along the sides of the ridges. The capture of one Japanese-held cave served only to disclose another, and one machine-gun position was overrun only to provide access to the next. Dislodging the Kembu Group from such defenses in depth was to prove a slow, laborious, and costly process, demanding the closest teamwork between the infantry and its supporting arms. Casualties, as a rule, would not be heavy on any one day--progress would be too slow and the troops would spend too much of their time pinned down awaiting fire from supporting weapons. But a daily attrition rate of about 5 men killed and 15 wounded for each battalion engaged would soon begin to have its effect.

Meanwhile the 160th Regiment swiftly captured Hills 636 and 600 in rapid succession. However, the 108th Regiment lost control of Hill G during the engagement. On January 26, Griswold committed the 37th Division to the fight, with the 145th Regiment successfully capturing Mabalacat and Mabalacat East Airfield. They then shifted westward across Route 3, overrunning Clark Field Runway Number 1. In the Cabaruan Hills, American forces gained only 150 yards at a considerable cost. In response, Patrick decided to deploy another battalion from the 1st Regiment to eliminate this pocket of resistance. The following day, this two-battalion assault proved successful, resulting in the destruction of an entire battalion of Japanese troops, with over 1,400 enemy soldiers killed. Further north, the 161st Regiment finally broke through the main defenses of Shigemi’s forces. Before dawn most of the Japanese left in San Manuel scrambled across the draw on the east side of town and fled to join the 10th Reconnaissance Regiment north of San Nicolas, but not before launching a final counterattack to cover their escape. At 0930 the 161st Infantry's two battalions resumed the drive southward through the town, and by 1330 San Manuel was clear. In a heroic but tactically unimportant stand the Shigemi Detachment had virtually fulfilled its self-imposed desire for annihilation in place. The detachment had lost 750 men killed; all its tanks, artillery, trucks, machine guns, and mortars had been either captured or destroyed. Probably no more than 250 troops escaped, and many of them were unarmed and wounded. The 161st Infantry and attached units had lost approximately 60 men killed and 200 wounded; the 716th Tank Battalion lost 3 tanks.

Meanwhile, Wing's offensive continued on January 27, with the 103rd Regiment successfully reaching the crest of Hill 700 and the northwestern slopes of Hill 600. Unfortunately, they lost both positions to a brutal Japanese counterattack amidst a violent tropical downpour. On January 28, the 172nd Regiment captured Rosario, while the 63rd secured the southern crest of Hill 1500. Both regiments completed the capture of this strategic feature by January 30, thereby finalizing the occupation of the crucial road junction area. Further south, on January 27, the 160th Regiment advanced only 500 to 800 yards to the west and southwest. The 108th Regiment made a more substantial advance of about 1,000 yards southwest from Hills E and G but failed to reach Hill 5. The 145th Regiment pushed south along Route 3 for an additional three miles, reaching Culayo and Dau before taking control of the guerrilla-occupied Angeles, which had recently been abandoned by the retreating Yanagimoto Detachment. In a similar vein, the 148th Regiment secured Magalang without encountering any resistance.

As we shift our focus from Luzon, we turn our attention to Burma, where we will delve into the ongoing developments of Operation Capital. Picking up from our previous discussions, we find ourselves in Central Burma, where the 2nd British Division and the 19th Indian Division are making significant strides toward Shwebo. The 2nd British Division successfully captured Ye-u on January 2, followed by the establishment of a crucial bridgehead across the Mu River just three days later. Meanwhile, the 19th Indian Division also advanced, reaching the Shwebo area by January 5.

On January 8, a coordinated assault was launched by units from both divisions, culminating in the capture of Shwebo after two days of intense and brutal combat. To the west, General Festing’s 29th Brigade began probing the northern flank of the 15th Division at Twinnge. Concurrently, other elements of the 19th Division worked to solidify their positions by establishing additional bridgeheads over the Irrawaddy River at Thabeikkyin and Kyaukyaung. On January 10, the 20th Indian Division captured Budalin and subsequently pushed towards Monywa, where the 33rd Division had only left a small contingent to serve as a rearguard. However, the campaign faced unexpected challenges; heavy rainfall during the first week of January brought all transport operations of the 4th Corps to a standstill, significantly hampering the Lushai Brigade's planned assault on Gangaw.

After enduring a heavy aerial bombardment, the attack on Gangaw finally commenced on January 10. The Lushai Brigade managed to overpower the limited defending forces, forcing them to retreat after a brief skirmish. With Gangaw now under their control, the Lushai Brigade refocused their efforts on reconnaissance, monitoring the flanks of the 7th Indian Division. Meanwhile, the 28th East African Brigade took the lead in the advance, successfully displacing a Japanese garrison at Tilin on January 22. By this time, the 114th Brigade had begun to follow in the wake of the East Africans, while the 89th Brigade executed a long maneuver to the left, advancing toward Pauk in parallel with the other offensives. Although General Kimura was aware of some movements on his southern flank, he perceived these as mere feints by minor forces intended to divert his attention southward.

Following a relentless barrage of artillery and air strikes, the 20th Division launched its offensive against Monywa on January 20. This assault faced fierce resistance, and it took two days of intense and bloody combat before the division was able to secure control of the town. After capturing Monywa, the 80th Brigade advanced towards Myaung, while the 110th Brigade shifted its focus to Ayadaw before launching an attack on Myinmu. By January 25, they had successfully established a bridgehead in that area. Meanwhile, to the east, the 2nd Division commenced its assault on Sagaing on January 14. They made significant headway against the forward defenses of the 31st Division, with other units managing to secure a bridgehead at Ywathitgyi. General Katamura, concerned about the expanding bridgeheads established by the 19th Division across the Irrawaddy River, ordered the 15th and 53rd Divisions to neutralize these positions before they could become fortified.

As a result, during the last week of January, the Japanese forces executed a series of coordinated night attacks on Kyaukmyaung. By this time, British-Indian troops had dug in deeply, supported by formidable artillery and machine-gun positions. The ensuing conflict was marked by brutal carnage, with the 15th Division suffering a staggering loss of one-third of its personnel, while the 53rd Division was compelled to withdraw to Kyaukse after incurring heavy casualties. In parallel, the 89th Brigade successfully occupied Pauk on January 28, as General Messervy’s forces geared up for a decisive push towards Meiktila. Looking northward, General Sultan was also advancing his own offensive aimed at reopening the Burma Road to China. He ordered the 50th Chinese Division to move towards Lashio and deployed the Mars Task Force to Hosi. Additionally, he dispatched the 36th British Division towards Mongmit, although the British advance was expected to be slow until additional forces could be brought into alignment for a more coordinated effort.

General Sun’s newly established 1st Army initiated a delayed offensive against Namhkam, which resumed in early January. This resurgence was marked by the 90th Regiment's strategic capture of the hill that overlooks the southwestern entrance to the Shweli River valley. Concurrently, the 112th Regiment advanced through Loiwing, subsequently crossing the river to approach Namhkam from the northeast. Meanwhile, the 88th Regiment entered the valley via the main road, making a direct push across the small plain toward Namhkam. The 89th and 114th Regiments executed a broader maneuver around the southern end of the Shweli valley; the 89th crossed the river on January 7 and advanced northward toward Namhkam, while the 114th crossed three days later, navigating through the hills toward the Namhkam-Namhpakka trail.

To the south, the 475th Regiment progressed through Mong Hkak and reached Mong Wi on January 6, preparing for another challenging march across the hilly terrain toward Hosi, with the 124th Cavalry Regiment following closely behind. So close is Tonkwa to the mountains that the 475th found the trail rising steeply on the 1st day's march east. Like a crazily twisted drill it bored its way farther east and ever higher. In some places it was 15 to 20 feet across; in others, just wide enough for a man and a mule. As they rounded the turns, the men would peer ahead and look out across the valleys to where lay row on row of hills. Trees were everywhere. In flat places carved by erosion, the Burmese had cut and farmed terraces, and little villages clung to the mountains like limpets to a rock. Because existing maps were unreliable, so that map reconnaissance could not locate water and bivouac areas, and because the sheer fatigue of climbing the steeper slopes was formidable, march schedules went down the mountain side, with quite a few steel helmets and an occasional mule. Halts were a matter of common sense leadership at platoon or company level. The march was tactical but no Japanese were encountered, though rumor of their nearness kept the men alert. The Chinese had passed that way before, while a screen of Kachin Rangers was preceding the American column. Speaking the local dialects and carrying radios and automatic weapons, the Kachins were an excellent screen which masked the MARS Task Force while reporting anything that might be suspicious. Despite the difficult march, crossing the 400-foot wide Shweli was not too hard. The bridge built by the Chinese some weeks before still stood, a triumph of Oriental ingenuity, with bundles of bamboo for pontons and vines for cable. The Shweli was beginning to tear it apart, but work parties from the 475th kept it operable. 

Meanwhile, spurred into action by General Wedemeyer after a month of inactivity, General Wei’s Y-Force finally resumed its offensive operations in late December. They promptly dispatched the 2nd, 6th, and 71st Armies to launch an assault on the forward positions of the 56th Division at Wanting. Simultaneously, the 53rd Army executed a wide flanking maneuver to the west, aiming to encircle and attack the Japanese forces from the rear. Faced with the intense pressure of this four-pronged offensive, General Matsuyama was compelled to withdraw the 148th Regiment to a position north of Mongyu. He also ordered the Yoshida Force to mount a counteroffensive toward Muse and committed the reserve 2nd Regiment to secure Namhpakka. On January 5, the 53rd Army reached the vicinity of Muse and began crossing the river; however, they were met with fierce resistance from Matsuyama's timely counterattack, which thwarted their advance.

Ten days later, Sun’s forces initiated a well-coordinated offensive against Namhkam, which ultimately succumbed on January 16 as the 55th Regiment retreated toward Khonung. With the Shweli Valley now firmly under Allied control, Matsuyama began to tighten his defensive perimeter in anticipation of a final withdrawal toward Hsenwi. On January 17, the Mars Task Force made significant progress by reaching the Hosi sector, where they immediately engaged Japanese outposts. The 475th Regiment successfully secured the advantageous high ground near Nawhkam village. Over the next two days, American forces clashed with the 4th Regiment, capturing the strategically important Loikang Ridge and the elevated terrain overlooking Namhpakka. On January 19, the Mars Task Force attempted to disrupt Japanese supply lines by blocking the Burma Road through demolition and artillery bombardment, coinciding with the arrival of the 55th Regiment, which was sent to bolster the defenders. In a parallel effort, the 114th Regiment managed to sever the Namhkam-Namhpakka trail at Loilawn on the same day.

Faced with this escalating threat from the south and the intensifying Chinese assaults on Wanting, the 56th Division was compelled to further contract its defensive perimeter. As a result, Wanting fell on January 20. Fortunately for Matsuyama, General Wei received orders from the Generalissimo to conclude the Salween campaign immediately, which meant that the Chinese forces would remain in their positions until they could be relieved by Sultan’s units. Over the course of nearly nine months of intense combat, Wei’s Y-Force had successfully reoccupied an impressive 24,000 square miles of Chinese territory and had defeated one of the most elite divisions of the Japanese army, along with elements from two additional divisions. However, the fighting was far from over. Sun continued to dispatch the 112th and 113th Regiments toward Wanting and Mongyu, aiming to clear the final stretch of the road leading to China. Meanwhile, the 89th and 114th Regiments pressed eastward to cut off the Burma Road north of Namhpakka, further complicating the situation for the Japanese forces.

In the southern region, from January 20 to January 24, the Mars Task Force continued its strategic operations, executing ambushes and demolition missions while successfully repelling several intense counterattacks from enemy forces. By late January, pressure by MARS Task Force and that of the Chinese forces in the north began to register on the Japanese. The soldiers of the 4th Regiment could see the aerial activity that kept MARS supplied. Not recognizing what they saw, they were so impressed by a big supply drop on the 24th that they sent a report to the 56th Division of a large airborne force being landed along the Burma Road. Accepting this report, General Matsuyama decided to destroy his ammunition and retreat south. His superiors on January 24 agreed to let him retreat, but only after he had evacuated casualties and ammunition. Forty vehicles with gasoline accompanied by a Major Kibino of the 33rd Army staff were sent north to support the 56th in its withdrawal. The Japanese truck convoy made its run north the night of January 24. The trucks were heard, and the Americans placed heavy fire on the road. Kibino had been making the trip in a tankette. Hit by a 4.2-inch mortar shell, it burst into flames clearly visible from the American lines. Kibino clambered out, jumped on a truck, and succeeded in getting his convoy through to the 56th Division. Next day the derelict tankette was credited to the 2nd Battalion, 475th Regiment. But  Encouraged by the additional supplies of gasoline and inspired by the heroic examples of Major Kibino and the personnel of the truck companies, the 56th Division renewed its efforts and, during the next four days effected the evacuation of over 1000 casualties and moved several tons of ammunition to Hsenwi. 

Meanwhile, General Matsuyama began to systematically reposition his forces toward Namhpakka, a strategic maneuver that would enable Chinese troops to occupy Mongyu on January 27. In a broader context, by the end of January, the 36th and 50th Divisions were also engaged in crossing the Shweli River, preparing to advance their offensives further southward. In the Arakan region, Operation Romulus exceeded expectations. The 1st Battalion of the 111th Regiment had been defending Akyab. On December 31, as the rear guard of the Sakura Detachment crossed the Kaladan River and moved eastward the Battalion was ordered to withdraw to Ponnagyun. As intelligence suggested very few Japanese were left on Akyab island, a recce aeroplane reported the locals showing no anxiety and on January 2 messages were dropped in Urdu and Burmese asking them to sit on the ground if the island was still occupied or stand with their hands in the air if not. Captain Jimmy Jarrett of ‘C’ Flight, 656 AOP Squadron, then landed to a rousing reception and found the Japanese had quit on December 31, although nobody believed him until a senior officer flew in to confirm it.

This prompted General Christison to swiftly initiate an amphibious invasion. Notably, this operation was executed without the anticipated naval bombardment and without deploying the reserve 26th Indian Division. As a result, the 3rd Commando Brigade successfully captured Akyab on January 3, facing no resistance, and the 25th Indian Division soon followed, reinforcing the area. From Akyab, the 9th York and Lancasters were transported by boat to establish a strategic blockade along the Yo River at Ponnagyun. There, they encountered significant Japanese forces. After a fierce engagement, however, the Japanese defenders were compelled to retreat toward Myohaung by January 11. In response to the evolving situation, Admiral Mountbatten devised a plan to land the 3rd Commando Brigade and the 25th Division on the Myebon Peninsula. This operation aimed to sever the primary lines of communication for Japanese forces, while preparations were made for the 26th Division to conduct a landing on Ramree Island.

In response to the urgent military situation, Operation Passport was swiftly conceived and executed on January 12. British-Indian forces successfully landed at the southern tip of the peninsula, supported by both air and naval operations. Once ashore, the commandos advanced inland, facing intense resistance from fortified hill positions. Their efforts culminated in the capture of Pagoda Hill and the village of Myebon. However, as they pushed forward, opposition intensified, making it increasingly difficult for the British-Indian troops to reach Hill 831.

Simultaneously, the 82nd West African Division, now commanded by Major-General Hugh Stockwell, entered the Kaladan Valley to relieve the 81st Division, which had been engaged in combat for over a year. The West African forces began to apply pressure against the Matsu Detachment units stationed at Myohaung and Minbya, although these Japanese forces managed to maintain their positions despite the mounting assaults. Meanwhile, planning was underway for the deployment of the 3rd Commando Brigade and the 51st Indian Brigade to land at Kangaw, coinciding with General Lomax’s invasion of Ramree Island. 

Early on January 21 the naval bombardment group opened fire. Christison and the other Force Commanders were watching through field glasses from the bridge of HMS Queen Elizabeth in her first engagement since the Dardanelles in 1915. Christison later said: ‘Some shells fell on a marsh behind the Jap defences, and I saw a number of duck spring up. “Duck”, I shouted. “The Royal Navy never ducks”, said the Admiral.’ With her second salvo Queen Elizabeth scored a direct hit on the Japanese ammunition depot, which facilitated the landing operations. The 71st Indian Brigade successfully captured Kyaukpyu with minimal resistance. This victory enabled them to advance toward Minbyin and Kyaupyauk, both of which fell into their hands by January 23.

In the subsequent days, the brigade continued its advance toward the Yanbauk Chaung, where they encountered fierce Japanese defenses. At the same time, other elements of the division worked to secure Cheduba and Sagu Kyun Islands, further consolidating their strategic position in the region. On January 22, the commandos and the 51st Brigade successfully landed in the Kangaw area near the Min River. However, they faced violent and frequent counterattacks from Japanese forces, which hindered their ability to expand their beachhead. Despite these challenges, the intense pressure from the commandos ultimately forced the Japanese defenders at Hill 831, Myohaung, and Minbya to retreat toward Kani, marking a significant shift in the operational landscape.

General Krueger's forces advanced against Japanese defenses, capturing key positions despite heavy resistance and casualties. Meanwhile, in Burma, British-Indian troops advanced, seizing key locations despite heavy resistance. Both fronts faced intense combat, leading to significant territorial gains against Japanese forces by the end of January.
