Last time we spoke about the landing at Saidor and continuation of advances upon New Guinea and New Britain. Operation Michaelmas was a huge success, isolating countless Japanese and threatening those trying to retreat further north. Taking advantage of the new front on New Guinea, the Australians began pushing more so upon the features across Shaggy Ridge and towards Sio. General Adachi frantically shifted units around in an effort to plug up the multiple advancing allied units, but in the end there was little to be done as the Japanese were pushed further and further north. Features were taken upon Shaggy Ridge and Sio fell nearly uncontested. Over in New Britain, General Rupertus triumphed over the Airdrome and his Marines were expanding their perimeters. Katayama made a bold attack against an enemy he overestimated at it certainly did not pan out for his men at suicide creek.

A while back I covered the start of the Chinese-Indian offensive into the Hukawng Valley and Arakan regions. When I did so it was almost entirely from the allied viewpoint, but what of the IJA war planners? The Burma campaign has been arguably a complete disaster for the allies, the Japanese steamrolled all the way through, claiming vast amounts of territory and key cities and ports, so what really did they need to do but garrison it all? After Wingate unleashed operation Longcloth, the relatively idle Japanese raised the idea of potentially attacking India. Lt General Mutaguchi Renya, the victor of the Singapore campaign in 1942 was made a commander in Burma and wargamed the possibility of attacking India to try and earn support from his superiors at Tokyo General HQ. It was his belief, they could brush past the British in Assam and reach the gateway into India, and he expected the Indians to rise up and greet them with open arms. A lot of money and effort had been spent on Subhas Chandra Bose and his Indian National Army. The fall of India would be an absolutely devastating blow to the British Empire in Asia and in 1942 there was even the belief the Japanese could link up with their German allies in the middle east. But that was 1942, before Stalingrad and Kursk, 1944 was a very very different geopolitical situation. This however did not stop Mutaguchi from continuing his plans to invade India. Lt General Hanaya Tadashi, commanding the Arakan front was given the task of convincing the British that the counterattack in Arakan was the appearance of the main army earmarked to conquer India, thus leading General Slim to send up reserves from Imphal. The operation was codenamed HA-GO and it was intended to be a fent to mask the real attack upon Imphal designated Operation U-GO. Now let me dig a bit deeper into how this all came about.

Until now, General Stilwell had been able to build much of the Ledo Road practically unmolested. Yet by early August, General Kawabe Mazakazu’s Burma Area Army was preparing for a counter offensive. Kawabe actually did not trust Mutaguchi and suspected the man was harboring megalomaniac designs to invade India, which he was 100% right about. The “counter offensive” was really just the beginnings of Operation U-GO and it had been sold to Tokyo HQ as a pre-emptive strike to disable the 14th Army and make it unable to invade Burma. Thus General Mutaguchi’s 15th Army was given the task of destroying any hostile elements in the Imphal region and to establish a strong defensive line. From December 22nd to the 26th, Mutaguchi held a conference pushing for the possibility of launching Operation U-GO and developed detailed missions for each division which would participate by means of a war game. At the same time Kawabe sold the operation HA-GO the diversionary attack in Arakan, with Lt General Hanaya Tadashi’s 55th Division earmarked to pin down as many of the enemy’s units as possible and to draw the British reserves away from the main offensive.

When General Christisons offensive kicked off, this forced Kawabe to reinforce Hanaya with the 54th division, and this in turn established the 29th Army under the command of General Sakurai on January 6th. The 29th Army was under the overall command of the Burma Area Army, and its HQ was initially situated in Moulmein. It was assigned to defend the coastal region of Arakan and the lower Irrawaddy valley and consisted at first of the 55th Division in Arakan, the 54th Division in reserve in Prome, and various garrison units including the 24th Independent Mixed Brigade in Moulmein. It also controlled the 11th Shipping Detachment of Major-General Suzuki Gisaburo, consisting of the 11th Shipping Engineer Regiment and the 3rd Sea Transport Battalion. It had roughly 1,105 men, 85 large landing barges, 54 small landing barges, 47 motored sampans, two armored boats, 10 fishing boats, one messenger boat and one speed boat. The 11th Shipping Detachment was stationed at Taungup and its main supply depot was at Prome.

Meanwhile after the capture of Maungdaw, the 5th Indian division of Major General Harold Briggs was ordered to attack the main Japanese defenses at Razabil. Razabil’s defenses were quite formidable, it dominating the crossroads and road linking Maungdaw with the Tunnels and Buthidaung located 3 miles eastwards, forming the 15th Indian Corps immediate objective following Maungdaw's capture. It was dubbed by its Japanese commander “The Golden Fortress of the Mayu Range”. It was centered on the railway tunnels running through the Mayu Range and at Point 551 to the east with a further forward position at Point 1301. These powerful defenses, built carefully exploiting the rugged mountainous terrain, were tunneled deep into the hills and consisted of bunkers, trenches and other fire positions located amidst dense jungle and camouflaged with customary Japanese skill. The main outworks at Letwedet to the east and at Razabil to the west of the Mayu Range were major fortresses in their own right, requiring careful reduction before the main position could be tackled. With both bastions in direct line of sight from the Tunnels, accurate supporting artillery could be called down with ease, moreover, adding to the problems already facing troops assaulting trenches and bunkers dug into the hillsides invulnerable to all but direct hits by medium artillery.

The offensive against Razabil was codenamed Operation Jonathan, but it would be delayed until the corps artillery became available. At the same time the 7th Indian division seized the initiative on January 18th and launched an attack against the 55th division’s position between Letwedet and Htindaw. The 9th company, 143rd infantry regiment was defending a hill east of Htindaw and stood their ground against repeated attacks until January 24th. The Japanese strongpoints were well dug in on the tops of narrow ridges. On January 26th, Major General Briggs ordered the 161st brigade, with support in the form of Lee-Grant tanks, artillery and aerial bombardment to attack the Tortoise defended by 1st battalion, 143rd regiment in the Razabil area. The Tortoise was a horseshoe defensive position that dominated the highway. It was an elaborate system of bunkers, trenches and all the typical Japanese goodies. For the boys in Burma it would be the first time for most to face such a thing, as Slim wrote in his memories “This was the first time we had assaulted an elaborate, carefully prepared position that the Japanese meant to hold to the last."

The attack opened up with 12 Vultee Vengeance dive bombers of the 3rd Tactical air force, 12 Mitchell medium bombers and 16 Liberator heavy bombers of the Strategic air force followed up by even more dive bombers. It was a visually spectacular event and to those observing from the ground looked devastating. However little to no damage was inflicted on the strongly constructed Japanese defenses burrowed so deeply into the hillsides. Similarly the mountain artillery regiment and batter from a field regiment did little damage with their bombardment as well. The Japanese had simply pulled back 1000 yards during the bombardments and by the time the allies surged forward came back to man their positions. When the Indians began their assault, the fire coming down the steep and jungle clad hillsides was absolutely devastating. The Lee-Grant tanks fired from the valley floor and managed to destroy all the identified bunkers, but the exposed Indian troops suffered massive casualties. It was virtually impossible to keep the defenders heads down long enough to advance even 50 yards towards the summit. Things got even worse when the men reached the defensive lines for the Lee-Grant tanks had to lift their fire lest they hit their own men. By the end of the day, only a toehold had been secured over the lower slopes of Razabil ridge.

The assault carried on for 3 more days, with intense tank and artillery fire from different directions supporting the infantry as closely as possible. The only immediate effect of the bombardment and indirect fire by 25 pounders and 3.7 howitzers was to destroy the vegetation over the hillsides, thus exposing more and more of the Japanese defensive works. During the intense battle, the Lee-Grant medium tank proved itself a real solution in providing effective covering fire for infantry and soon new techniques were evolving. The Japanese defenses were mainly built over the summit of steep, thick, jungle covered hills and the Lee-Grants provided fire support from positions in the paddy fields below them. Their 75mm guns effectively destroyed or at the least neutralized bunker positions. A procedure was quickly developed for providing cover during the last stages of infantry assaults. Tanks would use high explosive shells to clear the vegetation, than delayed action high explosive shells to break up the front of visible bunkers, then armor piercing shells to enable the infantry to advance close behind the creeping barrage as shrapnel was not flying everywhere. All combined this showed the potential of armor vehicles in jungle warfare, when most claimed they had little practical use in such climats. Despite such developments, the casualties were mounting, little progress was being made.

On January 28th, the 123rd brigade attacked Japanese positions on the secondary hill of Wrencat and its smaller neighbor hill Wrenkitten, probably the best hill names I have read on this podcast as of yet haha. These were located on the lower western foothills of the Mayu range. They were extremely steep, cone shaped features with fortified circular trenches around their heads, bunkers, and bamboo jungle. Firing from positions on the valley floor the Lee-Grants and 5.5 inch artillery were able to destroy the bunkers and switch to armor piercing rounds to perform creeping barrages for the infantry. Despite the tank and artillery support, the Japanese were throwing a ton of mortar, grenade and machine gun fire. An officer of the 123rd brigade involved in the fight had this to say 'It appears from our experience that consolidation on the objective which normally consists of a series of deeply constructed bunkers connected one with the other is extremely difficult in the very limited time that the enemy allow.' The failures against the Tortoise and Wrencat, prompted General Christison to call off the attack against Razabil by January30th. Christison regrouped his corps artillery and tanks to instead support the 7th divisions assault against Buthidaung and Letwedet.

Meanwhile further to the north, General Tanaka had brought 6300 men of the 55th and 56th regiments to the Hukawng valley by early January. He wanted to counterattack in strength, but General Mutaguchi believed he could not spare additional motor transport units to give the necessary logistical support to the 18th division since preparations were already going on for operation U-GO. Thus, Tanaka ordered his men to perform a delaying action down the Hukawng valley with the primary objective of holding Kamaing, the ridge line separating Hukawng valley from Mogaung valley. Tanaka weighed his orders and the looming monsoon season that hit the area in May or June. Against Tanaka, Stilwell sought to continue his offensive after successfully taking Yupbang Ga. Stilwell now looked towards Taihpa Ga and convinced both General Wingate and Admiral Mountbatten to unleash the Galahad long penetration unit into the Hukawng valley.

On January 4, 1944, Frank Merrill abruptly relieved a disappointed Brink. Despite having a background with cavalry, like Brink, Merrill understood the Japanese strength, but unlike Brink he respected the chain of command. General Sun met with Stilwell and and it was agreed the bulk of the 114th regiment should swing widely around Tanaka’s left flank while the 113th regiment wheeled to the south to hit Tanaka’s front along the Tanai Hka. Further north the 2nd battalion ,112th regiment would also advance east across the Tarung Hka to secure Warang Ga; the 65th regiment would continue their advance towards Taro, fording the Tanai river by January 9th; south of Kantau, the 3rd battalion, 114th regiment ran into two Japanese companies. The jungle made it difficult for the Chinese forces to organize themselves. The battalion split into 4 fragments and no two of them were in contact. The supporting 6th battery could not fire until fields of fire were cut and while that was being carried out, the Japanese companies performed infiltration maneuvers and quickly surrounded the battery. Fighting for their guns and lives between the 9th and 11th of January the Chinese cannoneers managed to save both. The battalion was nearly wiped out from these Japanese tactics, but thankfully on January 12th, the regimental HQ arrived and reformed the battalion to launch a concerted attack that managed to gradually push back the Japanese. 3 days later the 2nd battalion arrived allowing the 114th regiment to force a crossing of the Sanip Hka by January 16th.

Meanwhile the 1st battalion, 113th regiment forded the Tarung river near Yupbang Ga and sent patrols north to occupy Tabawng GA on January 13th. From there they advanced southeast to Kaduja Ga then to Brangbram Hka where they formed a line extending to the junction with the Tanai bank by mid january. On January 21st, the Chinese broke through the Japanese lines north of Brangbram Hka and made it to Ningru Ha less than one mile downstream from Taihpa Ga. Simultaneously, the battered 112th regiment swung wide going north east to Warang Ga. By the end of January the 113th continued their advance upon Taihpa Ga where they would meet stronger Japanese resistance. They began fighting within 1,500 yards of Taihpa Ga. Artillery support, the 4th and 5th Batteries, was then brought up. The next 1,000 yards between the 113th regiment and Taihpa Ga took two days to cross; then they spent a week in what was called "preparations for attack." General Sun's men were now approaching the Japanese strongpoint in the area, and Japanese resistance was more freely offered, with heavy shelling by 75- and 150-mm. pieces. At Taihpa Ga, the Kamaing Road crossed the Tanai on a long gravel bar which bullock carts could use quite well. At this point was the village itself, a humble collection of bashas, long since burnt out. About 800 yards upstream was a ferry across a stretch of fairly deep water. The Japanese used this ferry to bring supplies across the Tanai, rather than the vulnerable and easily spotted gravel bar. Here they had their strongpoint, well prepared and stubbornly defended.

Further to the west, the 65th regiment advance was much slower than expected for Stilwell.  Upon reaching the Hukawng Valley, the 65th's commander, despite means more than ample for his mission, contracted the same lethargy that had hastened the demise of the 112th Regiment. Stilwell was greatly frustrated by the delay a few more weeks with Colonel Fu, so he ordered Colonel Liao to relieve him. Stilwell wrote in his diary "Told Liao this included division commanders unless they watched their step. Also that Fu really should be shot. Liao took it OK though it shook him up." On January 22, General Sun was told about this affair, but the news softened somewhat by the presentation of a silk banner for the victory at Yupbang Ga, a dramatic contrast of the respective awards for lethargy and vigor. Having made his point, and hoping that he had given the Chinese a healthy shock, Stilwell restored Fu to his command by January 26. Fu's later performance in combat was rated as excellent.

The Chinese managed to encircle the passive 3rd battalion, 55th regiment on January 23rd, and by the 25th the last Japanese pockets were wiped out. On the 26th the Chinese reached Ahawk Hka and on the 28th crossed the Taro river and occupied Taro on the 30th. This effectively cut behind Tanaka’s flank. The bulk of the 112th now was close enough to the 113th to aid them so Sun began an attack against Taihpa Ga on the 30th. The Japanese held on stubbornly for days and would quietly withdrew on the night of February 4th. Tanaka concluded the loss of the Taro plain meant "the failure of the whole division in its operations along the Tanai". Thus Tanaka decided there was no point in continuing the fighting there. Over at Sanip, Sun ordered the 3rd battalion, 114th regiment to rest. However Stilwell thought this was close to disobedience of his orders,  because he wanted Sun to move quickly and cut behind the 18th Division. On January 13, he had spoken very bluntly to Sun, asking him what orders he gave the 114th Regiment and if there had been any word from Chongqing to slow the operation. Stilwell told Sun that if he could not exercise the commands that Peanut had given him, he would resign and report the whole affair to the US Government. "Regardless of what anyone else may say, I assure you that my report will be fully believed in Washington." General Sun was confronted with the prospect that Chinese lethargy in north Burma might mean withdrawal of all US help from China. Stilwell, Sun was told, had been alone in his fight to convince the United States that the Chinese Army was worth helping. "If I am double-crossed by the people I am trying to help I am through for good and I will recommend very radical measures." Stilwell closed by saying that he had done his part; would Sun reciprocate? But despite Stilwell's arguments and threats, General Sun did not meet Stilwell's ideas of how a dynamic field commander should conduct himself.

Thus the 114th gradually began to dislodge the Japanese from their positions along the river bank, taking care to annihilate all pockets behind. Stilwell was satisfied with the progress of his offensive and established the northern combat area command on February 1st. This organization would be led by Brigadier General Haydon Boatner and would include American, British and Indian units entering North Burma. But that is all for the wild Burma front as we now need to travel over to New Guinea.

Last time we were in New Guinea, Brigadier Chilton’s 18th brigade had just completed their advance upon Shaggy Ridge and Brigadier Hammer’s 15th brigade had just relieved the 25th brigade on January 7th. Thus two brigades were flown in and two were flown out, showcasing how far the allied New Guinea air forces had increased their efficiency during the war. The New Guinea force was now under the command of General Milford, though Vasey still retained his task of  "contain hostile forces in the Bogadjim-Ramu area by vigorous action of fighting patrols against enemy posts”. The division's role was still to prevent enemy penetration into the Ramu-Markham valley from Madang and protect the Gusap airfield and the various radar installations the instruction added that the division would "create the impression of offensive operations against Bogadjim Road by vigorous local minor offensive action". This was to be done by holding in strength with two brigades a "line of localities" from Toms' Post on the right to the Mene River on the left, the boundary between the 18th on the right and the 15th on the left being a line from Bebei through Herald Hill to Kankirei Saddle. In addition the 18th Brigade would "by raids and harassing tactics ensure that no major Jap withdrawal takes place undetected and occupy the Mindjim-Faria divide and the high ground to the north and south of it as the administrative position permits". The 15th Brigade would hold the Yogia-Mene River area, delay any enemy advance up the Ramu from the Evapia River, patrol to the Solu River, and deny the 5800 and 5500 Features to the enemy.

Despite this, Vasey was preparing to assault the Kankirei saddle with the fresh 18th brigade. Designated Operation Cutthroat, the seizure of the Kankieri saddle and ultimately that of Shaggy Ridge, Vasey planned to launch an attack against Mount Prothero which was being defended by the 6th company, 78th regiment. He would attack it from the south, preceded by a diversionary attack against Cam’s saddle. Brigadier Chilton realized however, that frontal attacks along Shaggy Ridge would not be able to achieve surprise, so he instead wanted to attempt a wide encircling maneuver on the left flank via Canning’s saddle to attack Prothero directly. The 18th brigade spent the early part of January patrolling to see if it was possible to advance through Canning’s saddle to Prothero 1 while simultaneously and stealthily building a road to Canning’s in preparation for the coming offensive.

The possibility of occupying Prothero from Canning's Saddle had been suggested to Chilton by Lt-Colonel Lang of the 2/2nd Pioneers, after a patrol performed by Captain McInnes. Captain McInnes had found an approach along a steep, razor backed spur within a short distance of Prothero’s summit where they could hear Japanese. Meanwhile the 2/9th battalion had sent a patrol that found a possible track from McGullough’s ridge vie Geyton’s Hill to the Mene River. Going up the river bed led one to Canning’s saddle. Two companies of the 2/12th spent a few days constructing a track going to the Mene River and they took special precautions to prevent the enemy from finding out. Reconnaissance patrols in general were careful to avoid contact with the enemy and so was the case around Prothero. The jeep track was hurriedly pushed to Guy's Post, existing tracks were improved and shorter and better tracks constructed to improve the supply routes to Shaggy Ridge and Mainstream; reserves of supplies in forward areas were built up, thus enabling a concentration of as many natives as possible to carry for the attacking battalion on the left, and arrangements were made for a limited air dropping at Canning's Saddle at an appropriate time.

To support the upcoming attack, 9 long and two short 25 pounders of the 2/4th field regiment were brought up along with 7000 shells. The guns had to be dragged forward to the Lakes-Guy’s Post area. Lt Colonel Charles Bourne’s 2/12th battalion was to head the attack. Chilton also planned to have Lt Colonel Charles Geard’s 2/10th battalion perform a diversionary attack through Cam’s saddle. After Protharo 1 was captured, the 2/10th were to exploit north to Kankieri and south to the Mainstream area; while Lt Colonel Clement Cummins 2/9th battalion attacked northwest along Shaggy Ridge to join up with the 2/12th. By January 18th, the 4000 yard track to Geyton’s Hill was complete, allowing the 18th brigade to advance. On that same day, B-25 Mitchell bombers unleashed their cannons and bombed the enemy positions at the junction of Mainstream, the Faria and Shaggy ridge. They dropped 60 delayed action bombs over the Faria river valley and some modified Mitchells sporting 75mm cannons mounted on their chins fired upon the crest of ridges. This cannon, the same used by Sherman tanks, was quite a formidable weapon in the air. To enable its fire, the nose of the B-25G model had to be shortened and the cannon breech positioned behind the pilot from where it could be loaded by the navigator for firing. To fire it the pilot would press a button on his control wheel. The weapon would prove inefficient against shipping, but it would be a lot more successful at hitting ground targets. Over three successive days from 18 to 20 January the Mitchells flew 180 sorties against Shaggy Ridge, firing 135 rounds of 75 mm at the ridge as well as dropping around 200 tons of bombs. The aircraft also fired about 90,000 rounds of .50 caliber. The machine-gun salvos were particularly devastating. From his accompanying Boomerang, Alex Miller-Randle recalled ‘Mitchells strip the trees of Shaggy Ridge clean and shatter the limbs and trunks to matchsticks’.

D-day was the 20th, seeing the 2/10th on the right and 2/12th on the left. Captain Kumnicks company of the 2/10th advanced to Grassy Patch and over on the left a party of the 2/12th led by Major Fraser took vanguard. All of the preliminary actions were completed back on the 19th when Captain Gunn’s A company of the 2/10th advanced from Tom’s Post for Sprogg’s ridge via a Japanese mule track. Later Captain Humnicks D company would use the same track. On the left the 2/12th battalion and B and D company of the 2/2nd Pioneers advanced along the new line of communication to Geyton’s. At 8:45am Captain Gunn’s company advanced from Sprogg’s ridge to attack Cam’s Saddle, followed 30 minutes later by Captain Kumnick’s company. Operation Cutthroat opened up with artillery and B-25 mitchell bombardments against the Protheros and Kankirei Saddle. By 11 a .m. Captain Gunn was 300 yards from an enemy position on Cam's Saddle while artillery shelled the position until 12.30 pm when the Australians found that the enemy had withdrawn.

Farther on, Captain Gunn’s men would be pinned down by Japanese defending the western end of the saddle as Japanese patrols ambushed a signal line party 500 yards behind. Gunn initially tried to outflank the enemy, but then withdrew 200 yards and dug in for the night astride the mule track. At the same time, the 2/12th battalion reached Canning’s Saddle by 3:30pm. The next morning, the 2/12th began to silently creep along the razor back ridge towards Prothero 1 with Cameron’s C Company taking the lead. At this point Fraser had Captain Cameron’s C Company, Captain Geason’s A Company  and Captain Thomas’s D company enveloping the ridge. They nearly achieved surprise, but the Japanese discovered their advance and rapidly turned their mountain gun upon them causing many casualties. Despite the mountain guns fire, Lt Braithwaites 8th Platoon charged the Japanese and captured the mountain gun upon Prothero 1. The action cost 11 Australian lives with another 44 wounded. The 2/12th had thus captured the key point in the Japanese defenses upon Shaggy Ridge. After the loss of the mountain gun position, Colonel Matsumoto ordered his men to pull back closer to Kankirei. In the process the 2/10th were able to capture Cam’s Saddle. On that same day the 2/9th began their attack, sending A Company to envelope the Green Sniper’s Pimple defended by a platoon of the 78th regiment. A Company managed to seize the position using stealth and would be met by failed counterattacks. By the end of the day the Japanese defenders were now sandwiched between the 2/9th to the south and the 2/12th to the north, while the 2/10th were advancing from the east.

Way further to the east, General Nakano’s men were in an even more dire situation. After the evacuation of Sio, the Japanese were forced to retreat day and night under heavy rainfall, hindered by rough terrain and allied aerial attacks. Lieutenant General Yoshihara Kane, Chief of Staff of the 18th Army, recalled this of the march: “The most wearing part was that with these ranges, when they climbed to the craggy summit they had to descend and then climb again, and the mountains seemed to continue indefinitely, until they were at the extreme of exhaustion. Especially when they trod the frost of Nokobo Peak they were overwhelmed by cold and hunger. At times they had to make ropes out of vines and rattan and adopt "rock-climbing" methods; or they crawled and slipped on the steep slopes; or on the waterless mountain roads they cut moss in their potatoes and steamed them. In this manner, for three months, looking down at the enemy beneath their feet, they continued their move. Another thing which made the journey difficult was the valley streams, which were not usually very dangerous. At times, however, there was a violent squall, for which the Finisterres are famous during the rainy season; then these valley streams for the time being flowed swiftly and became cataracts. Then there were many people drowned... General Shoge was swept away by one of these streams on one occasion but fortunately managed to grasp the branch of a tree which was near the bank and was able to save one of his nine lives.”

The men were malnourished, fatigued, but kept going day by day anticipating an abundant food supply at Gali. When they reached Gali in late January they would find nothing there. This anguish was just the beginning. The base had been shelled by allied warships and bombed by allied aircraft. General Muroya was injured on January 17th during the bombardment. Luckily for the Japanese there was no offensive towards Gali. Since the Saidor landing, General Martin’s men were busy expanding the perimeter with outposts extending towards Sel and Bilau. Martin was reinforced with the 1st and 3rd battalions of the 128th regiment on January 16th. Although Martin believed launching an eastern attack upon the withdrawing enemy would provide an excellent opportunity to destroy some of their divisions, General Kreuger refused to permit such a thing. This was because the 32nd division was required for an upcoming offensive in the Hansa Bay area.

Meanwhile General Nakai had brought the bulk of his detachment over to the Mot River area and established a strong outpost on Gabumi. Nakai also sent the 3rd battalion 239th regiment to Bilau to try and contest the control of its outpost. On January 12, the Japanese attacked Biliau, forcing the Americans to retreat behind the river. 30 Americans then tried to retake the outpost the following day but were repelled by the Japanese. On January 15th, the Japanese withdrew, allowing the 1st Battalion, 128th Regiment to occupy it on January 20. Another Japanese attack on January 26 would force them to retreat; and two days later, the Americans were successfully ambushed when they tried to reoccupy the outpost. Nakano’s men had thus successfully carried out a fighting withdrawal from Lae. They had suffered horribly for it, crossing unbelievable difficult terrain, with basically no supplies, apart from what meager amounts could be airdropped or brought over via submarine. Yet now they needed to break through towards Madang, and there were 3 possible options of doing so. Number 1, they could advance along the coast, but this one was disregarded immediately because they would have to break directly through the new American defenses. Number 2, codenamed A would be an advance inland through Cabutamon, Monara, Sibog and Bilau towards Mindiri. Option 3 codenamed B was an advance even further inland crossing over the foothills of the Finisterre, through Nokopo, Kwembum, Yugayuga, Gabumi and Singor towards Mindiri. Nakano elected to send the 20th division over plan A while his division would advance in 3 echelons over plan B.

On January 23rd, the 51st division departed Gali along the B route while the 1st battalion, 115th regiment and General Katagiri’s 20th division would advance along the A route. Katagiri’s 80th regiment and 20th engineer regiment tried the best they could, but the march was only advancing a single kilometer per day. Katagiri’s troops had to cut through dense jungle and were facing strong enemy patrols along their route. Facing greater difficulties than expected, Katagiri decided to follow Nakano’s 51st division along the A route in the end. Yet unbeknownst to him, the 3rd battalion, 126th regiment had just established new outposts at Sibog and Paramusi on January 22nd. From there they were sending out patrols to Langani and Sindaman. The Americans still could not break through Nakai’s defenses at Gabumi giving the Japanese some relief. The bulk of Nakano’s forces were withdrawing smoothly, seeing just sporadic harassment from American patrols. On the 1st of February, the 1st battalion, 115th regiment finally made contact with Nakai’s forces at Gabumi while the bulk of the 51st division advanced through Yugayuga. A week later, Nakano himself reached Gabumi and began advancing towards Madang. By the 16th of February, the 1st battalion, 115th regiment reached Madang and the 20th division had successfully pulled out of Gabumi.

Late February would see 1667 men in total arrive at Madang, 5469 would reach Singor and 1235 would reach Gabumi. Thus 80% of Nakano’s strength had effectively withdrawn. Nakai also managed to collect 500 patients that had been abandoned at Yugayuga and brought them over to Madang by March 1st. It seemed once again, Nakano’s men had escaped doom. On the other side, Brigadier Cameron had begun his advance towards Saidor on January 25th. His 4th battalion led by Lt Colonel Percy Crosky, with a Papuan company reached Kiari on January 28th. Without taking a break they continued towards Singor the next day, then Malasanga and Crossingtown by the 31st.
