- 126 - Pacific War - Operation Ichi-Go Unleashed , April 16-23, 1944

Last time we spoke about the defense of India. General Mutaguchi’s megalomaniac dream of invading India was tossed into motion. Battles were raging over countless features and against formidable allied boxes such as the Lion Box. Yet Mutaguchi had relied far too heavily on seizing the allied supply depots while promising his subordinate commanders they would have ample supplies for their tasks. Those like General Sato became so angry with their superior they pretty much were acting insubordinate. The effort to take Kohima fully and thrust into India was falling apart battle by battle. Meanwhile within China, General Chennault's 14th air force was causing major problems for the Japanese, forcing them into action. Operation Ichi-Go was formed, a colossal offensive to neutralize airfields and perhaps end the China Problem once and for all. Meanwhile the Royal Navy received some breathing room in the mediterranean sea and were now moving into the Pacific Theater.

The Imperial Japanese Army, largely because of the losses incurred by the Imperial Japanese Navy and logistical constraints, was virtually powerless to stop the allied advance in New Guinea and the Solomon Islands. Imperial HQ predicted further losses in early 1944 and General Douglas MacArthur was expecting to sweep up the northern New Guinea coast so he could retake the Philippines. New Guinea was thus seen as a holding operation to delay the allied advance. With its shorter supply line, the Philippines was now being regarded as a good location to block MacArthur’s advance towards the home islands. Everyone of course was still waiting for the decisive naval battle. But back on the mainland, the IJA were not dependent on the IJN, their logistical constraints were not the same at all. Hence suddenly in 1944, the IJA decided to unleash incredibly large and bold offensives in Burma, Northern India and of course in China. 

On New Years day of 1944, Chiang Kai-Shek cabled President FDR warning him that the strategy they and Stalin had agreed on at the Tehran Conference in November of 1943, fully emphasizing the European Front was leaving China open to a major attack. “Before long Japan will launch an all-out offensive against China.” Yet western intelligence disagreed with Chiang Kai-Shek’s sentiment. While General Stilwell was completely focused on recapturing Burma, Chiang Kai-Sheks fears were about to be proven correct. In April of 1944, Operation Ichi-Go was launched. It was the largest military operation in Japanese history, it was also a last ditch effort to finally solve the so-called China Problem. It was obvious to the IJA, the IJN were losing the maritime war in the Pacific, thus they were determined to toss the dice in China. If they were successful, overland supply lines from Burma to Korea could be secured. In addition it would be a hell of a bargaining chip when negotiating with the Americans. If they could finally end Chiang Kai-Shek’s Kuomintang government, America would be facing the extremely formidable task of having to invade and reconquer China. Of course the immediate war aims were to knock out General Chennault’s air force some he would not be able to bomb Formosa or the home islands. Emperor Hirohito recalled in his Dokuhaku Roku, post-war testament “One shred of hope remained—to bash them at Yunnan in conjunction with operations in Burma. If we did that we could deal a telling blow to Britain and America …” 

By early April General Hata had amassed 62,000 men, 52,000 Japanese and 10,000 collaborationist units alongside 800 tanks, 1550 artillery pieces, 250 aircraft, 15550 motorized vehicles and 100000 horses. This would turn into 150,000 troops, and believe it or not that was the advance guard of a campaign that would eventually involve 500,000 troops. They would be supplied with enough ammunition for two years. The IJA air force amassed 200 bombers with enough fuel for 8 months to support them. Over the next 9 months, battles would be fought over 3 regions, Henan in central China to the east of Nanjing; Hunan and Guangxi in south China east of Hong Kong and Guangdong province and south of the Yangtze River. While Ichi-Go was unleashed, Chiang Kai-Sheks crack troops, the Y-Force based out of Yunan province, alongside Merrill’s marauders were busy fighting alongside Stilwell in northern Burma.

In spite of the efforts to keep Ichi-Go secret, during early 1944, the Chinese began fortifying their defenses and redeployed troops on a large scale to strengthen their frontlines. Chiang Kai-Shek knew something was coming, but his commanders believed a large-scale Japanese offensive in China was impossible by this point of the war. The Japanese began carrying out a heavy bombardment campaign, targeting Henyang, Guilin, Chongqing and against the heavy concentration of Chinese troops advancing in the Yangtze river area. The aerial attacks greatly hampered the KMT’s logistical lines. The Chinese reacted by unleashing their frontline artillery, destroying the Bawangcheng bridge on March 25th. The Japanese hastily went to work repairing the bridge as Lt General Uchiyama Eitaro’s 12th army would need to cross as pertaining to Operation Kogo. Kogo was the first phase of the battle aimed at opening the Pinghan Railway that ran from Beijing to northern Wuhan. South of Beijing is the Yellow River, that runs southwest to east. Uchiyama’s plan was initially to cross the Yellow River and secure the Zhengzhou area before driving south towards the Luohe area, where the Japanese would ultimately prepare for a drive towards Luoyang. 

On the night of April 17th, the main part of the 37th division crossed the Yellow River and advanced towards Zhongmu. The Japanese rapidly penetrated the defenders positions, taking them by surprise. Three KM’s in front of Zhongmu, they waited for the 7th independent Mixed Brigade to follow up behind them. The 7th Independent Mixed Brigade had crossed the Yellow River at the same time as the 37th Division, attacking the flank of the enemy facing the crossing point of the main body of the Brigade. Shortly after dawn the main body of the Brigade began crossing the river at a point near the left flank of the 37th Division. On the 19th, part of the 37th Division attacked Zhangzhou, completely routing the Chinese defenders while the bulk of the Division advanced towards Lihezhen. 

Meanwhile the 110th Division advanced upon Bawangcheng with the 62nd Division and 9th Independent Brigade following behind them. The 62nd Division was accompanied by the 3rd Armored Division and 4th Cavalry Brigade, setting out for Luohe with their tank support. The 110th División continued their advance towards Micunzhen, capturing the town by the 24th. On that same day the 9th Independent Brigade seized Sishuizhen, but would be unable to break through the 177th Division’s defenses. After a breakthrough was made at Zhengzhou, the 3rd armored division and 4th cavalry Brigades tanks advanced past the infantry to puncture the Chinese formations, forcing a quick rout. Meanwhile the 62nd Division, 37th Division and 7th Brigade reached the east-west line of Lihezhen and prepared for an assault on Xuchang. The Chinese simply were unable to respond to this. Chiang Kai-Shek and his commanders assumed this was a punitive expedition and that the Japanese would sooner or later turn back as they had always done in the past. As such, only the 15th and 29th Armies were sent to reinforce Xuchang to contain the Japanese offensive. Yet on the other hand, Uchiyama had also decided to divert his tanks and cavalry northwest, preparing for the future attack on Luoyang.

On the 30th, Uchiyama’s forces began attacking Xuchang, shattering the Chinese defenses at extreme speed and fully occupying the city by May 1st. The 62nd Division encountered the 15th and 29th Armies at Yingqiaozhen, battering them so heavily, the Chinese were unable to reinforce the vital railway. Two infantry battalions and one field artillery battalion of the 37th Division and the 27th Division departed Xuchang to continue marching south in order to re-open the Beijing-Hankou railway. The North China Area Army estimated that Tang Enbo would assemble his main force near Yehhsien, planning to advance to Yencheng and then wheel to the northwest in order to capture this force. However, the main force of the 31st Army Group of General Tang Enbo turned its advance to the north. The Area Army, therefore, changed its plan and decided to turn toward Loyang directly after the capture of xuchang, rather than to wait until Yencheng was captured. Yet we will have to wait until next week to find out what happens to General Tang Enbo’s forces as we are now traveling over to Burma. Don’t worry Operation Ichi-Go is just starting.

After the capture of Walawbum in early March, General Stilwell ordered Merrill’s Marauders to perform a wide envelopment, to cut the Kamaing Road behind General Tanaka’s 18th Division while the 22nd Division with tank support drove down the Kamaing Road from the north. Two Marauder battalions led by Lt Colonel Charles Hunter set out on March 12th, reaching Janpan 4 days later. Once there they received new orders from Stilwell to head south through the hills along the Warong trail, then make their way to Kamaian to block the road at Inkangahtawng. Meanwhile Merrills 1st battalion and their Chinese allies were facing strong enemy resistance. From bivouac areas in the hills northeast of Shaduzup, on the Kamaing Road, the 1st Battalion of the 5307th, followed by the 113th Regiment, moved out on the morning of 13 March to put the northern clamp across the Kamaing Road just south of the Jambu Bum, in the vicinity of Shaduzup. I & R Platoons followed some fresh footprints into an enemy bivouac and stirred up a hornet's nest of Japanese. There was brisk skirmishing, and though the Americans managed to cross the Numpyek Hka just beyond, the Japanese had been alerted and proceeded to delay them expertly. Lieutenant-Colonel William Osborne, commander of the 1st Battalion, decided to cut a fresh trail around the Japanese. This was painfully slow business, and waiting for an airdrop took another day. On 22 March, when Colonel Hunter to the south was one day's march from his goal, aggressive patrolling by Red Combat Team revealed that the Japanese had blocked every trail in the area through which Osborne had to pass, so again Osborne elected to make his own trail, this time over ground so rough that the mules had to be unloaded. The maneuver succeeded, and no Japanese were seen on 23 or 24 March. Osborne's march would have been greatly aided had he known Tilly's Kachin Rangers were in the same general area. By March 22nd they reached Hpouchye.

Additionally the 22nd Division and Colonel Browns tanks had been halling it through the Jambu Bum, making slow progress against heavy enemy resistance because of a lack of tank-infantry coordination. It was difficult to coordinate infantry and tank action, because the tankers found it hard to distinguish their countrymen from the Japanese. A few such cases of mistaken identity and the 22nd's men were understandably reluctant to get too close to the tanks. I remember a circumstance in WW1, when the IJA were laying siege to the German concession of Tsingtao. There was a small British force sent to aid the Japanese and so much friendly firing occurred, the IJA forced the Brits to wear their greatcoats to distinguish them from the Germans. So you know, it happens. By March 20th, Stilwell’s forces crossed the ridge, reaching Hkawnglaw Hka, but yet again the lack of tank-infantry coordination led them to pull back. Once over the Jambu Bum, the 22nd found the road down to be mined and blocked with fallen trees. Two days were lost in clearing the road, and then three battalions made a frontal attack, guiding on the road. Next day they tried a co-ordinated tank-infantry attack and the leading tank platoon reached the Hkawnglaw Hka about four miles south of Jambu Bum, destroying a few machine guns and taking four antitank pieces. But the infantry would not follow the tanks and dug in two miles short of the stream. The tanks patrolled till dark, then fell back to their own lines.

Over in the east, Hunter’s men departed Janpan and reached Inkangahtawng on March 23rd, setting up two road blocks. Hunter sent out patrols and quickly discovered Kamaing was wide open, yet the delay of Stilwell’s others units would force General Merril to deny any attempts to attack south. Tanaka’s reaction to the roads blocks were pretty intense. Beginning on he 24th, vigorous Japanese counterattack followed on another. The Morita Unit, about two companies strong were a hastily assembled force drawn from a battalion gun platoon, an engineer company, a medical company, and division headquarters; they were given two 75-mm. guns, placed under command of the 18th Division's senior adjutant, and rushed south to Inkangahtawng. Tanaka also ordered the 2nd battalion, 114th Regiment over at Kamaing to attack north along the Kumon Range. The attacks were so intense, Hunter’s men were forced to pull back to the Manpin Area by March 24th.

Meanwhile, Merrill’s 1st Battalion advanced to Chengun Hka, placing them really close to Tanaka’s headquarters at Shaduzup. To the north, the 64th and 66th Regiments managed to link up, but the relentless Chinese assaults continued to fail against the tenacious defenders costing the attackers many tanks and lives. It was the 2nd battalion, 66th's turn to lead on 21 March. Again the tanks got well ahead of the infantry. A combination of ambush and counterattack by the Japanese cost five tanks, and then the Japanese came on up the road, almost overrunning the battalion headquarters, which was saved by the courage of two engineer platoons that had been clearing the road. That night the 1st battalion, 64th, which had been making the enveloping move, came in from the east and cut the Kamaing Road, right in the segment held by the Japanese. A tank attack on the 23rd found Japanese antitank guns just south of a small stream north of the Hkawnglaw Hka that prevented the tanks from outflanking the position. The guns knocked out the three lead tanks in quick succession, blocking the road. After heavy fighting at the stream crossing, the tanks finally had to withdraw, leaving the derelicts. In the afternoon the two flanking battalions made their way up the road and joined the 66th. Unfortunately, the meeting of the 64th and 66th Regiments did not signal the end of Japanese resistance. Japanese and Chinese positions on the road were thoroughly intermingled, making movement in the immediate area extremely hazardous. An attempt to break the deadlock with the tanks failed when the device chosen to identify the Chinese infantry backfired. Both the Chinese and the Japanese waved white cloths at the tanks. The armor moved blithely on into a nest of Japanese antitank men, who destroyed five tanks with magnetic mines, effectively blocking the road. General Liao, the 22nd Division's commander, now cut a bypass road for the tanks around his west right flank. A tank platoon tried it, could not cross a ravine improperly prepared for tank crossing, came under artillery fire, and had to be withdrawn. General Liao then committed his 65th Regiment to the main attack, applying immense  pressure, prompting Tanaka to order his frontline regiments to withdraw 10 kilometers. 

On March 28th, Merrill’s 1st Battalion established themselves along the Nam Kawng Chaung on the Japanese rear, from where they would be able to attack Tanaka’s headquarters. Surprised, the Japanese chose to bypass the roadblock and evacuated their position via a track to the west. This resulted in Japanese resistance softening up, allowing the 65th Regiment to secure Shaduzup by March 29. At the same time, Hunter’s encircled Marauders were fiercely resisting the enemy attacks at Nhpum Ga, with his 3rd Battalion subsequently taking up positions at the Hsamshingyang airstrip to the north. The men were extremely fatigued, facing constant marches, dysentery, malaria and malnutrition. They fought on for 5 days under constant attack, successfully pushing back the relentless Japanese assaults.

On its hilltop the garrison, though suffering no shortage of food or ammunition, aside from the monotony of diet which was itself a hardship, suffered from an acute shortage of water. There were no plaster casts for the wounded, and they took their sulfadiazine dry. The pack animals could not be protected from the Japanese fire. When dead, their carcasses could not be buried, and the stench and the carrion flies added more miseries to the battle. Sergeant Matsumoto, who had played an important part at Walawbum, was a pillar of strength to the garrison, constantly scouting between the lines, overhearing Japanese conversations, and informing Colonel McGee accordingly. On one occasion, when Matsumoto learned of plans to surprise a small salient at dawn, the Americans drew back their lines, booby-trapping the abandoned foxholes. Punctually the Japanese attacked, straight into the massed fire of the waiting Americans. Throwing themselves into the foxholes for cover, they set off the booby traps. Matsumoto completed the debacle by screaming "Charge!" in Japanese, causing a supporting platoon to throw itself on the American guns.

An ailing General Merrill would be evacuated to Ledo, leaving Colonel Hunter to assume formal command of the Galahad Unit. He then sent his 3rd Battalion to counterattack, unsuccessfully attempting to clear the trail as the Japanese repelled all his assaults. Finally on April 4th, Hunter got a breakthrough. The Japanese were believed to be moving ever more troops up the Tanai and it was believed that the 1st Battalion, which had been ordered to aid, would not arrive for four more days at least. Hunter's reaction was to attack on the 4th with everyone but the sick and the mule skinners, with his large patrols called in and Kachins used to replace them. A fake fight, using carbines, which sounded like the Arisaka rifle, was staged to deceive the Japanese, and the air support made three passes at them. The first two were genuine, the last a feint which made the Japanese take cover, only to come out and find the American infantry on them. Hunter's force gained that day and came within 1,000 yards of the besieged. About this same time Capt. John B. George and a small party, sent north by Hunter to find the Chinese regiment which Hunter understood would support him in this area, met the 1st battalion, 112th regiment at Tanaiyang, about eight miles northeast. After an interval, presumably used to obtain permission to do so, its commander moved toward Hsamshingyang. His first element arrived at the airfield on 4 April and was used to guard a trail junction. Despite this increasing pressure the Japanese made a very heavy attack on the Nhpum Ga garrison, actually reaching the foxholes at one point, and being driven out by two soldiers using hand grenades.

Over the next few days, the Marauders were reinforced by the 112th regiment and Merrill’s 1st battalion, allowing Hunters men to crawl closer and closer to Nhpum Ga. By Easter Sunday,  the Japanese vanished, leaving cooking fires and equipment. There was no pursuit, as Stilwell wanted no movement beyond Nhpum Ga as they were facing large supply issues at this time. The battalion of the 114th made its way to Myitkyina, where General Tanaka, anxious about the town, added it to the garrison. The 1st Battalion, 55th Regiment, however, withdrew towards the vicinity of Warong. The Marauders had suffered 59 deaths and 314 wounded during the Inkangahtawn roadblock engagement and the siege of Nhpum Ga. The Galahad Unit and 114th regiment suffered so heavily from exhaustion, the men would be very weakened for future engagements. 

Further to the south, Stilwell was concerned about the recently offensives aimed at Imphal and Kohima, but he was relieved somewhat, when at the Jorhat conference of April 3, attended by Slim, Lentaigne, Stilwell and Mountbatten, he was told the situation was under control and for him to continue his northern offensive. During the conference, Slim also notified the others he had decided to divert the Chindits 14th and 111th Brigades, further south to help out his 4th Corps. However Brigadiers Fergusson and Calvert argued strongly against it, not wanting to get tangled up in the battle for Imphal. Calvert instead wanted to preserve White City and Broadway whilst Fergusson wanted another attempt at Indaw. The Chindits were still formally under the command of Stilwell in May and he wanted them to hold firm at Indaw to prevent the flow of Japanese reinforcements going north. It was estimated the Chindists could endure roughly 90 days of this action and would need to pull out my mid-June. This estimation did not sit well with Stilwell. General Lentaigne wanted to abandon the strongholds around Indaw and move north closer to Stilwell’s forces. Therefore, Calvert’s brigade would be prepared to open the drive to the town of Mogaung by attacking Mohnyin. Before this could occur, General Hayashi would initiated a general attack against White City on the night of April 6. 

The attack began with a three hour artillery bombardment, then the 1st and 2nd Battalions, 4th Regiment; and 3rd battalion, 114th Regiment stormed Calvert’s defenses. When the shelling died away, Hayashi’s three infantry battalions attempting to punch a hole along the southeast perimeter of the stronghold, defended by the Lancashire Fusiliers, Gurkhas, and other West Africans of the 6th Nigerian Regiment. Secure behind a row of machine guns with a line of mortars behind them, the defenders opened fire. Bullets and projectiles whipped through the air, the bright flashes of tracers lending an ethereal air to the proceedings. Rounds poured into the attacking Japanese who began to suffer heavy casualties. Determined bands of Japanese brought up Bangalore torpedoes to destroy the wire, but all malfunctioned. The battle went on for most of the night.

The Chindits fought like lions throughout the night and managed to toss back numerous enemy attacks. Then to their dismay 27 IJA medium bombers appeared,  blowing holes in the wire. The Bofors engaged them, shot down six and claimed six probables. Desperate efforts were made to repair the defenses before the next attack came in. White City received over 100,000 yards of barbed wire and 600 50ft coils of Dannert wire. The wire was 20 yards thick in places and festooned with mines and booby-traps. Dakotas continued to pour reinforcements into White City. The transport planes were relegated to flights during dawn and dusk times, but they kept coming, concentrating reinforcements at White City. Fresh companies of troops materialized to take up station, until in the words of Lt. Norman Durant of the South Staffords, the place was a “complete babel, for it contained  British troops, West Africans, Chinese, Burmans, a New Zealand RAF officer, Indians, and an American Neisei who acted as interpreter, or better said interrogator of prisoners. Large groups of West Africans from the 7th and 12th Nigerians landed, filling out the columns and battalions already at White City. As the planes continued to bring in reinforcements, Calvert managed to muster roughly seven battalions in and around “White City” against Hayashi. 

Over the next few nights, Calvert’s defenders continued to repel Hayashi’s attacks, until he was finally relieved by Brigadier Abdy Rickett’s 3rd West African Brigade on April 10th. This allowed Calvert to lead a strike force against Hayashi’s HQ at Mawlu from the south. While the Japanese continued their onslaught of White City, Calvert’s strike force advanced to Thayaung, before effortlessly seizing Sepein on the 13th. Then the 7th Nigerians fell upon Mawlu, prompting the HQ staff to flee south in a rout. With Mawlu now in their hands, the Nigerians soon found themselves under heavy fire, pinned down for the next four hours under relentless Japanese firing and dive-bombing by Japanese aircraft that put in a surprise appearance. Soon, the Gurkhas at Sepein also reported that they were under fire from the main Japanese positions at the edge of the village, hidden under mounds of flowering lantana scrubs. The sight was inordinately beautiful and lethal, concealing hordes of Japanese infantry, whose gunfire twinkled through the red, yellow, purple and green of the scrub. Three Gurkha ground attacks failed to dislodge the defenders and the men were becoming dispirited. Calvert decided to withdraw. As dusk settled at Mawlu, Vaughn began to pull his troops out of Mawlu and under the cover of a mortar barrage, taking with him a large collection of vital documents and an even larger trove of Japanese ceremonial swords and military equipment, which would serve as presents for Air Commando and RAF aircrews at White City.

While this was going on, Brigadier Brodies 14th Brigade were advancing to the Wuntho-Indaw railway where they managed to successfully attack the main bridge close to the Bonchaung Station,  interdicting the 15th Division’s lines of communication. To the northeast, Morris Force captured Myothit on April 9 and then continued to set up ambushes on the Bhamo-Lashio Road. Back at White City, Calvert decided to try and get behind the enemy from the flanks and hit them from the rear, pinning them against the stronghold’s wire. On the night of April 16, the Nigerians prepared an ambush on the Mawlu-Henu road, subsequently killing 42 Japanese. 

Yet realizing his strike force had trapped 2000 Japanese, Calvert ordered his men to infiltrate forward while the West Africans at White City launched an attack. This was met by a vicious and chaotic Japanese response as Hayashi’s men tried to break free. During these actions its estimated the Japanese suffered 700 casualties while Calvert suffered 70 men dead with 150 wounded. The last Japanese attack against White City occurred on April 17th. After this Calvert felt he could hold White City indefinitely, but Lentaigne was concerned with the looming monsoon season, so he ordered White City and Broadway to be abandoned on May 3rd in favor of a new stronghold codenamed Blackpool. The site chosen for Blackpool originally codenamed “Clydeside” was a stretch of hilly ground by the railway, near the village of Namkwin, some 32 km southwest of Mogaung. There was water and suitable places to build an airstrip and deploy the 25-pdr artillery guns when they got them. Beyond a large tract of paddy was a hill, which the troops christened “Blackpool Hill” which curved like the sharp-spined back of a wild boar, with the head down, fore-arms and legs extended sideways. The Blackpool position effectively blocked the railway and main road at Hopin, drawing closer to Stilwells forces.

The 11th Brigade had already been dispatched to the north to establish Blackpool. The now rested 16th Brigade managed to capture the Indaw West airfield by April 27th, facing no opposition. Ferguson noted, “This second approach to Indaw was an anti-climax, and for two reasons. First, just before we went in we were told that even if we captured the airfield of Indaw West, no troops, no divisions would be available from India for flying in: all hands and the cook, it seemed, were tied up in the great battle for Manipur. We were to capture the field for two or three days and then to abandon it…. Secondly, it was early apparent that the birds had flown. The Queen’s got right on to the airfield without a shot being fired.” Lentaigne also decided to abandon the Aberdeen stronghold, evacuating Ferguson’s men along with other units. 

Meanwhile, by the end of April, the Joint Chiefs of Staff had also decided that capture of Myitkyina was of vital importance to increase the Hump tonnage. This of course was heavily influenced by the new opportunity for land-based bombers in Chinese airfields to bomb Formosa, the Ryukyu islands, the philippines and the eastern Chinese coast. Now to capture the Moguang-Myitkyina area, Stilwell would receive the Ramgarh-trained 30th Division,the 50th and 14th Divisions, all of which were airlifted over the Hump in April. Stilwell’s plan was to drive down the Mogaung valley on Kamaing with such vigor as to persuade General Tanaka that this was the principal effort. The final directive on the 23rd, was for the 22nd Division to attack, rather than hold, and to swing the 64th and 65th Regiments around General Tanaka's left flank, while the 66th Regiment fought down the road. Once again the 112th was told to block off Kamaing from the south. The orders directed the "22nd and 38th to be in Pakhren and Lawa areas by April 27.  As Stillwell would remark in his diary “Now I've shot my wad,". Meanwhile the Marauder-Chinese force, now codenamed End Run would sneak east over the Kumon Range to attack Myitkyina directly.

Tanaka’s mission at this point was to hold Kamaing with all his strength until the rainy season while the 53rd Division, led by Lieutenant-General Kono Etsujiro moved to reinforce him. Elements of the 53rd Division began to sprinkle into the Indaw Area, but the Japanese HQ for northern Burma, from the newly activated 33rd Army led by Lt General Honda Masaki could not decide to commit them towards either Kamaiang or Myitkyina. Thus Tanaka’s hopes for a counterattack were lost. Tanaka received two understrength regiments, the 146th and 4th in April and May, both of whom had suffered terrible losses against the Chindits the previous month. By mid-April General Sun’s 38th Division was assembling in front of Tingring with the 114th regiment locked down in a fight with Tanaka’s 55th regiment. After a visit to the Sun’s command post on April 11th, Stilwell wrote in his diary: "At least it looks like a start! The piled-up inertia is terrible. . . ." On the next day the 114th Regiment relieved the 113th on the line of three villages all named Tingring. This move placed the 114th and 112th in line, the 112th to the east forming with its lines a small salient about Nhpum Ga. The 114th Regiment was operating in rugged terrain which was almost as much an obstacle as the delaying positions directly about Kamaing defended so skillfully by the Japanese. On at least one occasion the 114th lost its way and had to be located by aerial reconnaissance. The battle raged so heavily, it forced the 55th regiment to pull back, while the 114th regiment fought a Japanese rearguard from Hill 1725. By April 20th, they finally secured Tingring and quickly began a march south. On April 23, Stilwell ordered Liao to commence the drive south from Warazup, with the 22nd Division trying to make their way along Tanaka’s extreme left flank. The Chinese forces were advancing slowly however, very apprehensive because Chiang Kai-Shek had ordered Generals Sun and Liao to be as cautious as possible. And that is all for today on the Burma front as we now need to jump over to New Guinea. 

The last time we were talking about New Guinea, General Shoge’s 239th regiment at Madang were getting ready to cover the continued Japanese retreat to Hansa and Wewak. On the other side, General Vasey’s men were in hot pursuit. To the east, the 58th/59th battalion and Shoge’s 3rd Battalion were patrolling extensively in the Bonggu-Melamu area, playing a sort of game of hide and seek. Several patrols just missed one another in the Wenga, Barum, Damun, Rereo and Redu areas. There were also several clashes. For instance, on March 26, reports from local natives and police boys indicated that the Japanese were again approaching Barum, which had become the main trouble area, from the direction of Damun just to the north. Both sides engaged one another with fire, particularly mortar bombs, but the brush was a cursory one with neither side gaining any advantage. Exchange of fire and a few sporadic attacks by the Japanese continued for about five hours from 5 p.m. While Corporal Tremellen, in the leading section, was moving among his weapon-pits, with a Bren gun in his left hand and two magazines in his right, he was attacked but, not being able to bring his Bren into action, he bashed the Japanese over the head with the Bren magazines. This Japanese thus had the distinction of probably being the only one to be killed by the Bren magazine rather than what was inside it. This would all last until April 11th, when the Japanese had finally withdrawn back to Madang.

To the west, the 57/60th Battalion departed from Kwato on April 5 to rapidly secure Aiyau. From there they immediately sending patrols towards the Bogadjim Plantation. At this point, however, General Morshead had finally decided that it was time for Vasey’s 7th Division to get some rest, so General Boase’s 11th Division would assume responsibility for all units in the Ramu Valley and the Finisterres on April 8. Over at Atherton, General Herring had also retired in February, so General Savige had been appointed to command his 1st Corps. When recommending Savige's appointment Blarney had written to the Minister for the Army: “Two officers have been considered for this vacancy, Major-General S. G. Savige and Major-General G. A. Vasey. Both have been very successful in command in New Guinea operations, and I have some difficulty in determining the recommendations to be submitted, since each is capable and very worthy of advancement to higher responsibilities. Having regard to their respective careers, however, I recommend that Major-General S. G. Savige be appointed.” The significance of Blameys final sentence is a matter for speculation. It could hardly refer to past careers since Vasey's experience in command was wider than that of Berryman, a contemporary who had recently become a corps commander, and no less than Savige's. Alongside this Blamey also decided to do a changeover of corps HQ, seeing Savige take over 2nd Corps in the New Guinea front

On April 10, the 57/60th then managed to break through the Japanese bridge positions to the high ground beyond at Bau-ak while patrols reconnoitered Bwai on the Gori River. The attack on the 10th on the enemy position at Bridge 6—two step heavily-timbered spurs running down from each side of the Ioworo River and making a defile was described by Hammer as "a textbook operation and in actual fact it developed perfectly " . One platoon advanced down the road to "fix" the enemy positions while the remainder of the company encircled the enemy position to come in from the high ground to the north . In the first encounter the leading platoon lost two men killed and two wounded. While it engaged the enemy with fire the rest of the company with Lieutenant Jackson's platoon in the lead clambered into position and , later in the day, clashed with the enemy in a garden area on one of the spurs. For a while the Japanese held on, but the pressure of the Australians and the accurate fire from Private Hillberg's Bren in an exposed position in the enemy's rear forced them to withdraw . Towards dusk an Australian patrol moved down a track towards the road where a small Japanese band was found to be still resisting with machine-gun fire . The Australians did not attack for they were sure that the enemy would disappear during the night. As expected there were no signs of the Japanese next morning at Bridge 6 only bloody bandages and bloodstains on the tracks to remind the Australians of yesterday's fight. McCall occupied the area and sent patrols forward to Bau-ak, the last high ground overlooking Bogadjim. Two days later, Brigadier Hammer sent strong patrols forward to Bogadjim and Erima, which found no enemy resistance in front and managed to secure both important hubs by April 15. At this point, while the 18th Brigade began to be evacuated back to Australia, Brigadier Hammer decided to withdraw the 58th/59th Battalion and the 2/2nd Commando Squadron, as the 57/60th would be the only one to continue the advance to Madang. 

 

On April 17, however, General MacArthur instructed Savige that a brigade from General Ramsay’s 5th Division should relieve the 32nd Division at Saidor in preparation for the Hollandia-Aitape operation’s, so the 8th Brigade and portions of the 30th Battalion would be flown to Saidor five days later. Thus the 300 odd troops were carried over to Bogadjim as Savige ordered the 15th BRigade to rest up and for the 30th battalion to take Madang.  Hammer was anxious to get there first, so he had immediately dispatched patrols to Amele and Madang on April 20th. Shoge was able to fully evacuate Madang and join his comrades as they fled for Hansa. Amele was secured by the 24th, but the Australians would find it very difficult to cross the Gogol River afterwards. After this the 30th battalion and Hammer’s patrols landed at Ort and resumed their advance. Both units cleared the Japanese from the Huon Peninsula, before entering an abandoned Madang. During the Australian advance an enemy mountain gun fired a dozen shells, and there was a sudden burst of machine-gun fire and a couple of grenade explosions from somewhere in the Wagol area. The machine-gun fire did not appear to be directed at the Australians and the shells from the gun landed out to sea. In all probability this was the final defiant gesture by the rearguard of the 18th Army as it left its great base of Madang which had been in Japanese hands since 1942. Madang had been heavily hit by Allied air attacks and possibly some demolitions had been carried out by the retreating Japanese. The airfield was cratered and temporarily unserviceable; the harbor was littered with wrecks, but although the two wharves were damaged they could be repaired and Liberty ships could enter the harbor. The Australian advance through the Markham, Ramu and Faria Valleys was a tremendous ordeal. The 7th division suffered between September 18, 1943 and April 8, 1944 204 killed and 464 wounded while it was estimated the Japanese suffered 800 killed, 400 wounded and 800 died from disease. The occupation of Madang ended the Huon Peninsula and Ramu Valley campaigns. 

Meanwhile, the remainder of the 5th Division assembled at the Madang-Bogadjim area, fanning out patrols to the west and sending small detachment of the 30th Battalion to land on small islands off the coast, preparing a future advance against Alexishafen. Shoge’s detachment rejoined its parent division, the the 41st Division over at the Hansa area, allowing General Katagiri’s 20th Division to continue their advance to Wewak. The 51st Division who had already arrived at Wewak got to watch the allied airshow as Hansa and Wewak we bombed without mercy, seeing countless barges destroyed. This would hamper Katagiri’s efforts to cross the Ramu and Sepik Rivers. Meanwhile General Nakai came across an alternative route in late April known as the Wangan-Garun–Uru-Kluk-Bien-Marienburg-Kaup route. This allowed the 20th Division to resume their march to Wewak. On April the 29th a barge carrying Katagiri was intercepted by a PT boat. General Katagiri was killed in the engagement, leaving Nakai to assume formal command of the Division. After May 1, the 41st Division then began to follow Nakai’s route across the river, with all Japanese units leaving Hansa by May 15th and finally arriving at Wewak at the end of May after a 20-day movement. 

Meanwhile General Adachi’s plan for the coming weeks of April was for the 20th Division to immediately head towards Aitape, while the 51st Division would reinforce Hollandia once the 41st Division had reached Wewak. As such, a force was created around the 66th regiment led by Major-General Kawakubo. They were dispatched on April 19th, but would fail to arrive on time and would have to turn back to defend Wewak. Additionally, Adachi personally sent a part of his units under direct command to reinforce Hollandia. 

Now after the neutralization of Hollandia and the Palaus, General Teramoto’s remaining air units would have to move over to Manado and Genjem on April 15th, leaving only 25 serviceable aircraft from Major-General Inada Masazumi’s 6th Air Division at Hollandia. After April 3rd, although plagued by bad weather, the 5th Air Force virtually owned the air over Hollandia. There would be only one resurgence of air opposition, on April 11th. The Japanese 14th Air Brigade staged a small fighter force to Wewak which, despite the loss of a Tony to the 8th Fighter Squadron, shot down three P-47s of the 311th Fighter Squadron, a new organization that had lately arrived from the United States and had only begun operations at Saidor on April 7. The enemy force perhaps had withdrawn to Hollandia by the next day, because some twenty enemy fighters pounced on a straggling B-24 there and shot it down. Aerial gunners of the 403rd Bombardment Squadron claimed destruction of one of the interceptors, and the 80th Fighter Squadron claimed eight others destroyed. In this action, Captain Richard I. Bong scored his twenty-sixth and twenty-seventh aerial victories, thus topping the score of twenty-six victories established by Rickenbacker in World War I. Promoted the same day to major, Bong was taken out of combat and returned to the United States on temporary duty at the suggestion of General Arnold, who feared adverse reaction among younger pilots if Bong were to be lost in combat after establishing such a record.

Three were also small night attacks, combining 5th Air Force Liberators with Navy PB4Y's and Catalinas, made against Wakde Island during the early morning hours of 6, 13, and 16 April. These attacks seem to have been more profitable than similar missions against the Sentani airfields, probably because Wakde was only a small island easily identified by radar and so jammed with military objectives that a hit anywhere would be damaging. A captured Japanese diary recorded that the 6 April raid killed eleven men, destroyed a barracks, cratered the runway in five places, and destroyed or severely damaged ten planes. A daylight attack against Wakde by seven squadrons of Liberators was scheduled for 6 April, but weather forced its cancellation.

The 24th and 41st Divisions were also carrying out their last rehearsals for Operation Reckless. Allied ground and amphibious forces had been engaged in final preparations and training for the coming assault and, on 8, 9, and 10 April, had undertaken last rehearsals. The 24th Division's rehearsal at Taupota Bay, on the coast of New Guinea south of Goodenough Island, was incomplete. Little unloading was attempted, and the area selected did not permit the employment of naval gunfire support. The 41st Division had a more satisfactory rehearsal, with realistic unloading and naval fire, near Lae, New Guinea. The Final loading began on April 10th, with the LCIs leaving their loading points six days later in order to allow the troops aboard to disembark at the Admiralty Islands for a day of exercising, resting, and eating. Ships carrying the Persecution Task Force, meanwhile, moved out of the Finschhafen area on April 18 and on the same day rendezvoused with the vessels bearing the 41st Division towards the Admiralties. All convoys under Admiral Barbey then moved north around the eastern side of the Admiralties and, at 7:00 on April 20th, the various troops assembled at a rendezvous point northwest of Manus Island. Thus, all seemed ready for the beginning of another amphibious assault.

The Imperial Japanese Army tossed a final hail mary attempt to improve the war situation with the grand Ichi-Go offensive. If they could manage to seize their objectives, this would perhaps give them a better hand at the negotiating table. Because the allies certainly would not be keen on having to liberate most of China, it was a very bold strategy.
