The Battle of Imphal took place in the region around the city of Imphal, the capital of the state of Manipur in northeast India from March until July 1944. Japanese armies attempted to destroy the Allied forces at Imphal and invade India, but were driven back into Burma with heavy losses. Together with the simultaneous Battle of Kohima on the road by which the encircled Allied forces at Imphal were relieved, the battle was the turning point of the Burma Campaign, part of the South-East Asian Theatre of the Second World War. The defeat at Kohima and Imphal was the largest defeat to that date in Japanese history, with many of the Japanese deaths resulting from starvation, disease and exhaustion suffered during their retreat.
At the start of 1944, the war was going against the Japanese on several fronts. They were being driven back in the central and southwest Pacific, and their merchant ships were under attack by Allied submarines and aircraft. In southeast Asia, they had held their lines over the preceding year, but the Allies were preparing several offensives from India and the Chinese province of Yunnan into Burma. In particular, the town of Imphal in Manipur on the frontier with Burma was built up to be a substantial Allied logistic base, with airfields, encampments and supply dumps. Imphal was linked to an even larger base at Dimapur in the Brahmaputra River valley by a road which wound for 100 miles (160 km) through the steep and forested Naga Hills.
Imphal was held by the IV Corps, commanded by Lieutenant-General Geoffrey Scoones. The corps was in turn part of the British Fourteenth Army under Lieutenant General William Slim. Because the Allies were planning to take the offensive themselves, the corps' units were thrown forward almost to the Chindwin River and widely separated, and were therefore vulnerable to being isolated and surrounded.
The Indian divisions were composed of both British and Indian personnel. In each brigade, there was generally one British, one Gurkha and one Indian battalion, although two brigades (37th Brigade in 23rd Division and 63rd Brigade in 17th Division) were composed entirely of Gurkha units. Each division was supported by two field artillery regiments (usually British) and one Indian mountain artillery regiment.
In March 1943, the Japanese command in Burma had been reorganised. A new headquarters, Burma Area Army, was created under Lieutenant-General Masakazu Kawabe. One of its subordinate formations, responsible for the central part of the front facing Imphal and Assam, was the Fifteenth Army. Lieutenant-General Renya Mutaguchi was appointed to command this army in July 1943. From the moment he took command, Mutaguchi forcefully advocated an invasion of India. His motives for doing so appear to be complex. He had played a major part in several Japanese victories, ever since the Marco Polo Bridge incident in 1937, and believed it was his destiny to win the decisive battle of the war for Japan. He may also have been goaded by the first Chindit expedition, a raid behind Japanese lines launched by the British under Orde Wingate early in 1943. The Allies had widely publicised the successful aspects of Wingate's expedition while concealing their losses to disease and exhaustion, possibly misleading Mutaguchi and some of his staff as to the difficulties they would later face.
Mutaguchi planned to exploit the capture of Imphal by advancing to the Brahmaputra Valley. This would cut the Allied lines of communication to the front in northern Burma, where the American-led Northern Combat Area Command was attempting to construct the Ledo Road to link India and China by land, and to the airfields supplying the Nationalist Chinese under Chiang Kai-shek via an airlift over "The Hump" (the Himalaya Mountains). Although the staffs at Burma Area Army and at Southern Expeditionary Army Group (the supreme command for the Japanese forces in southeast Asia and the southern Pacific) had reservations over the scale of Mutaguchi's proposed operation, they were eventually won over by his persistent advocacy. Finally, Prime Minister Hideki Tojo and Imperial General Headquarters gave their approval to the plan.
Mutaguchi intended to isolate and destroy the Allied units in their forward positions and then capture Imphal. His plan was named U-Go, or Operation C. In detail:
At the insistence of Subhas Chandra Bose, leader of the Azad Hind (a movement which sought to overthrow British rule in India by force, with Japanese assistance), the Indian National Army made a substantial contribution. (Originally, the Japanese intended using them only for reconnaissance and propaganda.)
All of Mutaguchi's divisional commanders disagreed with the plan to some extent. Sato distrusted Mutaguchi's motives, and Yanagida openly derided his abrasive superior as a "blockhead." Yamauchi was already very ill and fatalistic. Their main reservations concerned supply. Mutaguchi had assumed that success would be achieved within three weeks, but adequate supplies after that period could be obtained only if the Japanese captured Allied supply dumps, as the torrential rains that spring season would inevitably make supply routes from the Chindwin impossible to traverse. Gambles such as Mutaguchi was making had worked in the past, but could no longer be relied upon, given nearly total Allied air superiority in the area and the improvement in morale and training of British and Indian troops. Mutaguchi proposed to use "Genghis Khan" rations, driving herds of buffalo and cattle rounded up throughout northern Burma across the Chindwin as meat rations on the hoof. However, most of these beasts died from lack of forage and their meat rotted many miles from the troops they were intended to supply.
There were other weaknesses in the plan, which were revealed as the campaign progressed. The Japanese assumed that the British would be unable to use tanks on the steep jungle-covered hills around Imphal. For ease of movement and supply, the Japanese left behind most of their field artillery, their chief anti-tank weapon. As a result, their troops would have little protection against tanks.
Based on his experiences in the campaigns in Malaya and Singapore and in the Japanese conquest of Burma in early 1942, Mutaguchi dismissed British and Indian troops as inherently inferior. The troops he had met on those occasions had generally been inadequately trained and led. The Allies had by now largely overcome the administrative and organisational problems which had crippled their early efforts in Burma, and their troops were far better trained and motivated.
In late February, a local Japanese counterattack was launched against Indian XV Corps in Arakan, using much the same tactics as Mutaguchi proposed to use. The engagement became known to the Allies as the Battle of the Admin Box. The attack failed when Allied aircraft parachuted supplies to cut-off troops, allowing them to stand firm, while the Japanese who had infiltrated behind them ran out of supplies. From this point onwards, the Allies were to place increasing faith and reliance on their transport aircraft. Also, the Japanese unexpectedly encountered a number of Indian tanks, to which the lightly equipped infiltrators had little counter. The planning of U-Go, however, was too far advanced to take account of these developments.
Even as the Japanese prepared to launch their attack, the Allies launched the airborne phase of the second Chindit expedition on 5 March 1944. Japanese officers such as Major-General Noburo Tazoe, commanding the Japanese Army Air Force units in Burma, urged Mutaguchi to divert troops from his offensive to secure the Japanese rear areas against the Chindits. Mutaguchi dismissed these concerns, claiming that in a few weeks he would occupy the air bases from which the Chindits were supplied.
When they received intelligence that a major Japanese offensive was impending, Slim and Scoones planned to withdraw their forward divisions into the Imphal plain and force the Japanese to fight at the end of impossibly long and difficult lines of communication. However, they misjudged the date on which the Japanese were to attack, and the strength they would use against some objectives. The Japanese troops began to cross the Chindwin River on 8 March. Scoones gave his forward divisions orders to withdraw to Imphal only on 13 March.
The 20th Indian Division held Tamu near the Chindwin, and Moreh a short distance to the north, where a large supply dump had been established. On 20 March, there was a clash between six Lee tanks of the 3rd Carabiniers and six Type 95 Ha-Go tanks leading Yamamoto's advance from the south. The lighter Japanese tanks were destroyed. Acting major-general Douglas Gracey was opposed to making any retreat, but on 25 March he was ordered to detach some of his division to provide a reserve for IV Corps. As this left the division too weak to hold Tamu and Moreh, they withdrew to the Shenam Saddle, a complex of hills through which the Imphal-Tamu road ran. The supply dump at Moreh was set ablaze, and 200 cattle there were slaughtered. The division fell back without difficulty, mainly because two of Yamamoto Force's battalions from the Japanese 15th Division (II/51 Regiment and III/60 Regiment) were delayed at Indaw in northern Burma by the Chindits and were unable to intervene.
Further south, the 17th Indian Division was cut off by the Japanese 33rd Division. Patrols from the division and from V Force (an irregular force of locally raised levies and guerrillas) warned Cowan of a Japanese force advancing against the rear of the division as early as 8 March, allowing Cowan to regroup the division to protect its rear. On 13 March, the Japanese 215th Regiment attacked a supply dump at Milestone 109, twenty miles behind Cowan's leading outposts, while the Japanese 214th Regiment seized Tongzang and a ridge named Tuitum Saddle across the road a few miles behind the 17th Indian Division's main position.
The Indian division began to withdraw on 14 March. At Tuitum Saddle, the Japanese 214th Regiment were unable to dig in properly before they were attacked by the 48th Indian Infantry Brigade on 15 March. The Japanese suffered heavy casualties and were forced away from the road. Further north, the Japanese captured the depot at Milestone 109 on 18 March, but Indian troops recovered it on 25 March. Cowan had taken steps to secure the most vulnerable point in the rear of his division, the bridge over the Manipur River. The division's rearguard crossed safely on 26 March, demolishing the bridge behind them. The division removed most of the vehicles, food and ammunition from the depot at Milestone 109 before resuming their retreat.
Both the Japanese and the Indian division had suffered heavy casualties. Yanagida, the Japanese 33rd Division's commander, was already pessimistic, and was apparently unnerved by a garbled radio message which suggested that one of his regiments had been destroyed at Tongzang. He therefore did not press the pursuit against the 17th Division, and advanced cautiously in spite of reprimands from Mutaguchi.
Scoones had nevertheless been forced to send the bulk of his only reserve, the 23rd Indian Infantry Division, to the aid of the 17th Division. The two divisions, supplied by parachute drops from Allied aircraft, made their way back to the Imphal plain, which they reached on 4 April.
Meanwhile, Imphal had been left vulnerable to the Japanese 15th Division. The only force left covering the northern approaches to the base, the Indian 50th Parachute Brigade, was roughly handled in the Battle of Sangshak by a regiment from the Japanese 31st Division on its way to Kohima. The Japanese 60th Regiment cut the main road a few miles north of Imphal on 28 March, while the 51st Regiment advanced on Imphal from the north-east, down the valley of the Iril River and a track from Litan, 23 miles (37 km) north-east of Imphal.
However, the earlier diversionary attack launched by Japanese 55th Division in Arakan had already failed. Admiral Louis Mountbatten, the commander in chief of the Allied South East Asia Command, had taken steps to secure aircraft normally assigned to the "Hump". Slim was able to use these to move the battle-hardened 5th Indian Infantry Division, including all its artillery and first-line transport (jeeps and mules), by air from Arakan to the Central Front. The move was completed in only eleven days. One brigade and a mountain artillery regiment went to Dimapur in the Brahmaputra valley, but the other two brigades, the field artillery and the divisional HQ went to Imphal. The leading troops of the division were in action north and east of Imphal on 3 April.
On the Japanese left flank, the INA's Subhas Brigade, led by Shah Nawaz Khan, reached the edge of the Chin Hills below Tiddim and Fort White at the end of March. From this position, the 2nd Battalion sent companies to relieve Japanese forces at Falam and to Hakha, from where in turn Khan's forces sent out patrols and laid ambushes for the Chin guerrillas under the command of a British officer, Lieutenant-Colonel Oates, taking a number of prisoners. In the middle of May, a force under Khan's Adjutant, Mahboob "Boobie" Ahmed, attacked and captured the hilltop fortress of Klang Klang. The 3rd Battalion meanwhile moved to Fort White-Tongzang area in premature anticipation of the destruction of Major General Frank Messervy's 7th Indian Infantry Division in the Arakan, which would allow it to receive volunteers.
During the early part of the offensive, the Bahadur Group of the INA apparently achieved some success in inducing British Indian soldiers to desert.
From the beginning of April, the Japanese attacked the Imphal plain from several directions:
The Japanese 33rd Division attacked from the south at Bishenpur, where they cut a secondary track from Silchar into the plain. A commando raid destroyed a suspension bridge, making the Silchar track unusable. The 17th and 23rd Indian Divisions were regrouping after their retreat, and Bishenpur was only held by the 32nd Indian Infantry Brigade (detached from 20th Division). The Japanese advanced through the hills to the west of Bishenpur, almost isolating the British in the village, but suffered severely from British artillery fire. Their leading troops were halted by lack of supply only 10 miles (16 km) from Imphal. Other Japanese advancing directly up the Tiddim-Imphal road were halted in Potsangbam 2 miles (3.2 km) south of Bishenpur, as troops of 17th Indian Division rejoined the battle.
Yanagida, the Japanese division's commander, had already infuriated Mutaguchi by his caution. He was finally relieved of command at the end of the month.
Yamamoto Force attacked the Shenam Saddle, defended by the main body of the Indian 20th Division, on the main road from Tamu into Imphal. This was the only metalled road the Japanese could use, and it was vital for them to break through to allow Yamamoto's tanks and heavy artillery to attack the main defences around Imphal itself. Only a few miles north of the saddle was Palel airfield, one of the only two all-weather airfields in the plain, and vital to the defenders.
A Japanese attack up the road on 4 April was disjointed; the infantry were not ready to take part and twelve Japanese tanks were caught exposed on the road by British anti-tank guns. From 8 April to 22 April, there was heavy fighting for five peaks which commanded the road east of the Saddle. The Japanese captured a number of them, but Indian and British counter-attacks regained some of those initially lost. Casualties were heavy on both sides.
Having failed to break through using the road, Yamamoto sent some troops through the rough terrain to the north of the Saddle to raid Palel airfield. The INA's Gandhi Brigade or 2nd Guerrilla Regiment, of two battalions led by Inayat Kiyani, took part in this attack. On 28 April, they attacked Palel. They tried to induce some Indian defenders to surrender, but the defenders rallied after initial hesitation. Another INA detachment carried out demolitions around Palel, but withdrew after they failed to rendezvous with Japanese units. The Gandhi Brigade was short of rations, having brought forward only one day's supplies, and also lost 250 casualties to shellfire after they pulled back from Palel.
The Japanese 15th Division encircled Imphal from the north. Its 60th Regiment captured a British supply dump at Kanglatongbi on the main Imphal-Dimapur road a few miles north of Imphal, but the depot had been emptied of food and ammunition.
A battalion of the Japanese 51st Regiment (which was commanded by Colonel Kimio Omoto) seized the vital Nungshigum Ridge, which overlooked the main airstrip at Imphal. This was a major threat to IV Corps and on 13 April the 5th Indian Division counter-attacked, supported by air strikes, massed artillery and the M3 Lee tanks of B Squadron of the 3rd Carabiniers. The Japanese had expected that the slopes were too steep for tanks to climb, and indeed Lee tanks had never been tried before on such gradients in action. The Japanese regiment had very few effective anti-tank weapons, and their troops were driven from the ridge with heavy casualties. The attackers also lost heavily; every officer of the Carabiniers and the attacking infantry (1st Bn, the 17th Dogra Regiment) was killed or wounded.
By 1 May, all Japanese attacks had come to a halt. Slim and Scoones began a counter-offensive against the Japanese 15th Division. This division was the weakest of the Japanese formations, and if it was defeated, the siege would be broken (once Kohima was recaptured). The progress of the counter-attack was slow. The monsoon had broken, making movement very difficult. Also, IV Corps was suffering some shortages. Although rations and reinforcements were delivered to Imphal by air, artillery ammunition had to be conserved.
The 5th Indian Division (joined by the 89th Indian Infantry Brigade which was flown in to replace the brigade sent to Kohima) and 23rd Indian Division (later replaced by the 20th Division) tried capturing the steep ridges, such as the Mapao Spur, held by the Japanese, but found these to be almost impregnable. Allied artillery was usually unable to hit Japanese positions on the reverse slopes, and the troops often stormed the summits of the ridges, only to be driven off by mortar fire and grenades from the reverse slope positions. IV Corps regrouped. The 23rd Indian Division took over the defence of the Shenam Saddle, while from the end of the May, 5th Division concentrated on driving north from Sengmai up the main road through Kanglatongi, while the 20th Indian Division advanced along the tracks and the Iril River toward Litan and Ukhrul, threatening the Japanese 15th Division's lines of communication.
By this time, the Japanese were at the end of their endurance. Neither the 31st Division which was fighting at Kohima nor the 15th Division had received adequate supplies since the offensive began, and their troops were starving. Lieutenant General Sato, the commander of the Japanese 31st Division, ordered a retreat at the end of May, so that his division could find food. This allowed Indian XXXIII Corps to drive the Japanese from Kohima, and advance south.
The troops of Japanese 15th Division were forced to abandon their defensive positions to scavenge for supplies in local villages or on the Japanese lines of communication. Mutaguchi dismissed the mortally ill Yamauchi, but this did not change matters. After driving rearguards from the Miyazaki Group (an independent detachment from the 31st Division) and the Japanese 60th Regiment from their delaying positions on the Dimapur-Imphal road, the leading troops of IV Corps and XXXIII Corps met at Milestone 109, 10 miles (16 km) north of Imphal, on 22 June, and the siege of Imphal was raised.
South of Imphal, 17th Indian Division had moved back into the line, facing the Japanese 33rd Division. During the first half of May, there were several Japanese air attacks on Bishenpur, and heavy fighting for the village of Potsangbam 2 miles (3.2 km) to the south, in which the British lost 12 tanks. The surviving crews of the 3rd Carabiniers were later flown out of Imphal to be reconstituted in India.
Major General Cowan planned to break the deadlock on this front by sending the 48th Indian Infantry Brigade on a wide left hook into the Japanese division's rear while 63rd Indian Infantry Brigade attacked them in front. The Japanese division's temporary commander (its Chief of Staff, Major General Tetsujiro Tanaka) planned at the same time to infiltrate through Indian 17th Division's front to seize vital objectives in the middle of the Indian positions. Both moves were launched almost simultaneously.
The Gurkhas of 48th Indian Brigade cut the road behind the Japanese on 18 May, but 63rd Indian Brigade were unable to break through to them, and 48th Brigade was forced to fight its way through the Japanese positions to rejoin the division, with heavy losses. Meanwhile, some of Tanaka's troops (the 214th Regiment) captured hills close to 17th Division's headquarters on 20 May. Because of the incursion into their own rear, the Japanese were unable to reinforce their forward troops, and over the following week the isolated Japanese were driven from their positions in the middle of the Indian division, many parties being wiped out.
A new forceful commander, Lieutenant General Nobuo Tanaka, took command of the 33rd Division on 22 May, and ordered repeated attacks which reduced many of his division's battalions to mere handfuls of men. In June, he received reinforcements (a regiment from the Japanese 53rd Division, and a detachment from the 14th Tank Regiment) and used them to launch another attack. After initial success, the fresh regiment suffered heavy casualties from shellfire. By the end of June, the 33rd Division had suffered so many casualties that they could make no further effort.
Yamamoto Force had also suffered heavy casualties, but before withdrawing, they launched two successful raids on Palel Airfield in the first week of July, destroying several parked aircraft.
Towards the end of May, the INA's 1st and 2nd Guerrilla Regiments (the latter commanded by Malik Munawar Khan Awan) had been redirected to Kohima. They moved north across the Japanese rear but by the time they reached Ukhrul, the Japanese had already begun to withdraw. They decided to attack Imphal instead. At Imphal, both units suffered some desertions, but not on the scale that the Commonwealth forces expected.
The Japanese had realised that the operation ought to be broken off as early as May. Lieutenant General Hikosaburo Hata, the Vice-Chief of the General Staff, had made a tour of inspection of Southern Army's headquarters in late April. When he returned to Tokyo, he reported pessimistically on the outcome of the operation at a large staff meeting to Prime Minister Hideki Tojo, but Tojo dismissed his concerns as their source was a junior staff officer (Major Masaru Ushiro, at Burma Area Army HQ). Messages were sent from Imperial Headquarters, urging that the operation was to be fought to the end.
Lieutenant General Kawabe travelled north from Rangoon to see the situation for himself on 25 May. Several officers whom he interviewed expressed confidence in success if reinforcements could be provided, but actually concealed their losses and the seriousness of the situation. At a meeting between Mutaguchi and Kawabe on 6 June, both used haragei, an unspoken form of communication using gesture, expression and tone of voice, to convey their conviction that success was impossible, but neither of them wished to bear the responsibility of ordering a retreat. Kawabe subsequently became ill with dysentery and perhaps physically unfit for duty. He nevertheless ordered repeated attacks, stating later that Bose was the key to Japan's and India's future.
Mutaguchi ordered the Japanese 31st Division, which had retreated from Kohima when threatened with starvation, to join the 15th Division in a renewed attack on Imphal from the north. Neither division obeyed the order, being in no condition to comply. When he realised that none of his formations were obeying his orders to attack, Mutaguchi finally ordered the offensive to be broken off on 3 July. The Japanese, reduced in many cases to a rabble, fell back to the Chindwin, abandoning their artillery, transport, and many soldiers too badly wounded or sick to walk. The Allies recovered Tamu at the end of July. It was found to contain 550 unburied Japanese corpses, with over 100 more dying amongst them.
The defeat at Kohima and Imphal was the largest defeat to that date in Japanese history. They had suffered 54,879 casualties, including 13,376 dead (plus 920 casualties in the preliminary battles in Assam). Most of these losses were the result of starvation, disease and exhaustion.
The Allies suffered 12,603 casualties.
The Japanese had also lost almost every one of the 12,000 pack horses and mules in their transport units and the 30,000 cattle used either as beasts of burden or as rations, and many trucks and other vehicles. The loss of pack animals was to cripple several of their divisions during the following year. Mutaguchi had sacked all of his divisions' commanders during the battle. Both he and Kawabe were themselves subsequently relieved of command.
In December, Slim and three of his corps commanders (Scoones, Christison and Stopford) were knighted by the viceroy Lord Wavell, at a ceremony at Imphal in front of Scottish, Gurkha and Punjab regiments. Slim was created KCB, the others were made KBEs.
By mid-1944, the Allied air forces enjoyed undisputed air supremacy over Burma. The last major effort by the Japanese Army Air Force had been over the Arakan in February and March, when they had suffered severe losses. During the Imphal and Kohima battles, they were able to make barely half a dozen significant raids.
IV Corps enjoyed close air support from fighter-bombers and dive bombers of 221 Group of the RAF. Allied fighter bombers and medium bombers shot up and bombed enemy concentrations, supply dumps, transport, roads and bridges all the way to the Chindwin river. The monsoon, which occurred every year from May to September, in no way diminished their activity. The RAF Third Tactical Air Force increased their sortie rate to 24,000 sorties during the worst four months of the monsoon, nearly six times the figure of the previous year’s record.
However, the most important contribution to the Allied victory was made by both British and American transport aircraft. The Allies could fly men, equipment and supplies into the airstrips at Imphal (and Pallel also, until the onset of the monsoon rains), so although cut off by land, the town was not without a lifeline. By the end of the battle the Allied air forces had flown 19,000 tons of supplies and 12,000 men into Kohima and Imphal, and flown out 13,000 casualties and 43,000 non-combatants. Among the supplies carried during the siege were over a million gallons of fuel, over a thousand bags of mail and 40 million cigarettes. Several thousand mules were used to supply outlying outposts, for example 17th Indian Division up the Bishenpur trail, so animal fodder was also flown in during the siege. Allied aircraft could also parachute ammunition, rations and even drinking water to surrounded units.
At the start of the battle, South East Asia Command had 76 transport aircraft (mainly C-47 Skytrain) available, but many others were dedicated to supplying the Nationalist Chinese under Chiang Kai-Shek, or to establishing USAAF bomber bases in China, via "the hump". Not even Admiral Louis Mountbatten, the Commander-in-Chief, had the authority to commandeer any of these aircraft, but at the crisis of the battle in the middle of March he nevertheless did so, acquiring 20 C-46 Commando aircraft (equivalent to another 30 C-47s). He was supported by American officers at SEAC and the American China-Burma-India Theater headquarters.
The 100th Indian Infantry Brigade was an infantry brigade formation of the Indian Army during World War II. It was formed in April 1920 at Jhansi. The brigade was assigned to the 34th Indian Infantry Division until June 1943, when it was transferred to the 20th Indian Infantry Division until the end of the war. It was known for its participation in Battle of Imphal or known as "Imphal Campaign" where it fought along with other Indian Infantry regiments converged to form the 20th Indian Division and drove back the Japanese Army back to Burma inflicting heavy losses. This was a turning point in the Burma Campaign, part of South-East Asian theatre of World War II.15th Division (Imperial Japanese Army)
The 15th Division (第15師団, Dai Jūgo Shidan) was an infantry division in the Imperial Japanese Army. Its tsūshōgō code name was the Festival Division (祭兵団, Sai Heidan), and its military symbol was 15D. The 15th Division was one of four new infantry divisions raised by the Imperial Japanese Army in the closing stages of the Russo-Japanese War (1904–1905). With Japan's limited resources towards the end of that conflict, the entire IJA was committed to combat in Manchuria, leaving not a single division to guard the Japanese home islands from attack. The 15th Division was initially raised from men in the area surrounding Nagoya under the command of Lieutenant General Okihara Kofu.1944 in India
Events in the year 1944 in India.20th Infantry Division (India)
The 20th Indian Infantry Division was an infantry division of the Indian Army during World War II, formed in India, and took part in the Burma Campaign during World War II. In the immediate aftermath of the War, the bulk of the division was deployed to French Indochina to oversee the handover from Japanese to French rule.23rd Infantry Division (India)
The 23rd Indian Infantry Division was an infantry division of the Indian Army during World War II. It fought in the Burma Campaign. It was then reformed as a division of the independent Indian Army in 1959.33rd Division (Imperial Japanese Army)
The 33rd Division (第33師団, Dai-sanjūsan Shidan) was an infantry division of the Imperial Japanese Army. Its call sign was the Bow Division (弓兵団, Yumi Heidan). The 33rd Division was raised in Utsunomiya, Tochigi prefecture, simultaneously with 32nd, 34th, 35th, 36th and 37th Divisions. Its headquarters were initially in Sendai. It was raised from conscripts largely from the northern Kantō prefectures of Tochigi, Ibaraki and Gunma.50th Parachute Brigade (India)
The 50th Parachute Brigade is a brigade-sized formation of the Indian Army, first formed in 1941. The brigade was initially raised as part of the Indian Army during World War II. It was formed in October 1941, during the Second World War, as an independent parachute brigade. Later it was one of two parachute brigades in the 44th Indian Airborne Division. Its main force is formed of battalions of the Parachute Regiment, which became the Parachute Regiment (India) after Indian independence in 1947.
The brigade's initial composition included 151st British Parachute Battalion, 152nd Indian Parachute Battalion, and 153rd Gurkha Parachute Battalion. When the British battalion was recalled to the United Kingdom, it was replaced by a 154th Gurkha Parachute Battalion. Other components of the brigade included 411th (Royal Bombay) Parachute Squadron, Indian Engineers and 50th Medium Machine Gun Company. The brigade took part in the Battle of Sangshak, which has been credited with delaying the Japanese forces moving up for the Battle of Imphal which allowed British and Indian reinforcement to reach Kohima.53rd Division (Imperial Japanese Army)
The 53rd Division (第53師団, Dai-gojūsan Shidan) was an infantry division of the Imperial Japanese Army. Its call sign was the Peace Division (安兵団, Yasushi Heidan). It was formed on 16 September 1941 at Kyoto and initially assigned to Central District Army. The nucleus for the division formation was the headquarters of the 16th division. The men of the 53rd Division were drafted from Shiga, Fukui, Mie and Kyoto prefectures, belonging to Kyoto mobilization district.
The 53rd Division was initially assigned as the reserve of the Southern Expeditionary Army Group in November 1943. In December 1943, the division sailed from Moji, with a stop-over in Kaohsiung and in January 1944 landed in Saigon and Singapore. On 29 April 1944, the division was assigned to the 33rd army, and arrived in the northern outskirts of Mandalay on 13 May 1944.
In June 1944 the 153rd Infantry Regiment was detached to reinforce the 33rd division in the ailing Battle of Imphal and was largely wiped out. The main body of the division took part in several battles against the Chindits, a large British and Indian long-range penetration force which was operating north of Indaw. In late May, they defeated a Chindit brigade to clear the lines of communication to the 18th division, but at the end of June the division was driven from Mogaung, with 1600 casualties.From January 1945, the division was used as a reserve force in the Battle of Meiktila and Mandalay, with the main body of the 53rd division staying south of Mandalay. The 119th infantry regiment was attached to the 18th division for its attacks on Meiktila. After the attacks on Meiktila were broken off, the remnants of the division attempted to hold a position near Pyawbwe but were overrun by allied tanks.Finally, after retreating south, the division suffered further heavy casualties to artillery fire and airstrikes in the Battle of the Sittang Bend in July–August 1945. The remnants of the division ceased fighting on the lower Sittang River on 17 August 1945, after the surrender of Japan.55th Division (Imperial Japanese Army)
The 55th Division (第55師団, Dai-gojūgo Shidan) was an infantry division of the Imperial Japanese Army during World War II. Its call sign was the "Sou" Division (壮兵団, Sou Heidan). It was formed on 10 July 1940 at Zentsūji, simultaneously with 51st, 52nd, 54th, 56th, and 57th divisions. The formation nucleus was the headquarters of the 11th Division. Its manpower came primarily from the four prefectures of Shikoku Island. The 55th Division was initially assigned to the Central District Army.
In 1941, the division was assigned to the 15th Army and participated in the Japanese conquest of Burma. The division had the 143rd Regiment detached to separately capture Dawei (Tavoy) and Myeik (Mergui), while the main troop had captured Mawlamyine (Moulmein) on 31 January 1942. In March 1942 the division fought for 14 days around the city of Taungoo against the weakened Chinese 200th Division. The fight ended when the Chinese broke through and disengaged. On 18 April 1942, the 55th Division had encircled the Chinese 55th Division, eventually wiping it out. During the Burma Campaign, the 144th Infantry Regiment was detached from the division and sent to New Guinea. The rest of the 55th was used to counter an ill-planned British attack at Donbaik (Sittwe (Akyab)) from 18 March 1943. By 3 April 1943 the division had started to advance past the Mayu range, eventually surrounding and defeating a number of British units; encountering stiffer resistance from May 1943 onwards. Mid November 1943 the 55th was still in the Arakan area. Finally, the division fought a failed offensive which become the Battle of the Admin Box in February 1944. On 19 February 1944, the commander of the 112th Infantry Regiment, at that time down from 3000 to 400 men, had broken radio communication with the division headquarters and withdrew his men. In the aftermath of the disastrous Battle of Imphal, the division was assigned to the 28th Army in Burma and, after retreating to the Irrawaddy river, was subordinated to 38th Army. On 15 August 1945, when the Surrender of Japan was spoken out, the 55th Division was in Phnom Penh.Azad Hind
The Provisional Government of Free India, or, more simply, Free India (Azad Hind), was an Indian provisional government established in occupied Singapore in 1943 and supported by the Empire of Japan, Nazi Germany, Italian Social Republic, and their allies.
It was a part of a political movement originating in the 1940s outside India with the purpose of allying with the Axis powers to free India from British Rule. It was established by Indian nationalists-in-exile during the latter part of the Second World War in Singapore with monetary, military and political assistance from Imperial Japan. Founded on 21 October 1943, the government was inspired by the concepts of Subhas Chandra Bose who was also the leader of the government and the Head of State of this Provisional Indian Government-in-exile. The government proclaimed authority over Indian civilian and military personnel in Southeast Asian British colonial territory and prospective authority over Indian territory to fall to the Japanese forces and the Indian National Army during the Japanese thrust towards India during the Second World War. The government of Azad Hind had its own currency, court and civil code, and in the eyes of some Indians its existence gave a greater legitimacy to the independence struggle against the British.However, while it possessed all the nominal requisites of a legitimate government, it lacked large and definite areas of sovereign territory until Japan gave it nominal authority of the Andaman and Nicobar Islands in 1943 and the occupation of parts of Manipur and Nagaland. Japanese officials made all the decisions, and throughout its existence it was entirely dependent on Japanese support.Immediately after the formation of the government-in-exile, Azad Hind declared war against the Anglo-American allied forces on the Indo-Burma Front. Its army, the "Azad Hind Fauj" (Indian National Army or the INA), went into action against the British Indian Army and the allied forces as part of the Imperial Japanese Army in the Imphal-Kohima sector. The INA had its first major engagement at the Battle of Imphal where, under the command of the Japanese Fifteenth Army, it breached the British defences in Kohima, reaching the salient of Moirang before suffering a catastrophic defeat as the Allied forces held, and Allied air dominance and compromised supply lines forced both the Japanese and the INA to retreat.The existence of Azad Hind was essentially coterminous with the existence of the Indian National Army. While the government itself continued until the civil administration of the Andaman Islands was returned to the jurisdiction of the British towards the end of the war, the limited power of Azad Hind was effectively ended with the surrender of the last major contingent of INA troops in Rangoon. The death of Bose is seen as the end of the entire Azad Hind Movement.
Some historians contend that the Azad Hind was a free and independent government.The legacy of Azad Hind is, however, open to judgment. After the war, the Raj observed with alarm the transformation of the perception of Azad Hind from traitors and collaborators to "the greatest among the patriots". Given the tide of militant nationalism that swept through India and the resentment and revolts it inspired, it is arguable that its overarching aim, to foster public resentment and revolts within the Indian forces of the British Indian Army to overthrow the Raj, was ultimately successful.Japanese Burma Area Army

The RAF Third Tactical Air Force (Third TAF), which was formed in South Asia in December 1943, was one of three tactical air forces formed by the Royal Air Force during the Second World War. It was made up of squadrons and personnel from the RAF and the air forces of the British Commonwealth. Third TAF was formed shortly after the establishment of South East Asia Command to provide close air support to the Fourteenth Army.
It was first formed on 19 December 1943 designated the Tactical Air Force (Burma) and renamed as the Third TAF on 28 December 1943. Along with parts of the USAAF Tenth Air Force, it was subordinate to Joint Allied Eastern Air Command which was also formed in December 1943.As the Air Force was formed, it was felt that at last British forces could go over to the offensive against the Japanese in the Burma Campaign. A start was made towards establishing a general offensive in Arakan in early 1943, but this was forestalled by a Japanese offensive. The Japanese were decisively beaten, but they shifted the focus of their attack to central Burma. Third TAF gave sterling service to Fourteenth Army during the Battle of Kohima and the Battle of Imphal, strafing and bombing the besieging Japanese troops, often at very low level.
After the defeat of the Japanese by IV Corps and XXXIII Corps in Assam, the monsoon intervened before many counterattacks could take place. After the enforced period of reduced operations, the Third TAF supported the advance of Fourteenth Army against the Japanese forces. However, command arrangement changes at the end of 1944 cutting short the life of the Third TAF. It was redesignated HQ RAF Bengal and Burma on 4 December 1944.The Third TAF had two commanders, Air Marshal John Baldwin up until 15 August 1944, and then Air Marshal Sir Alec Coryton.Renya Mutaguchi

The Women’s Auxiliary Service (Burma) (WAS(B)) was formed on 16 January 1942 and disbanded in 1946. The WAS(B)s were a group of British and Australian women who manned Mobile Canteens for the troops of Burma Command in World War II. They moved through Burma with the British Fourteenth Army living in dangerous and uncomfortable conditions, sleeping in bombed out, rat infested houses or tents with their stores and equipment brought in by air. They improvised stoves from old ammunition boxes. They were evacuated from Myitkyina on the last plane, and from the Battle of Imphal during the siege, but returned as soon as the Japanese retreated, eventually reaching Japan with the British Commonwealth Occupation Force. Many were mentioned in dispatches. General Slim later 1st Viscount Slim, Commander of the 14th Army known as the "Forgotten Army", said of them "They showed the highest standard of devotion and courage."
