The Burma Campaign in the
South-East Asian Theatreof World War IItook place over four years from 1942to 1945. During the first year of the campaign, the Imperial Japanese Army(with aid from Thai forces and Burmese insurgents) had driven British Commonwealth and Chinese forces out of Burma, and occupied the country. From May to December, 1942, active campaigning ceased, as the monsoonrains made tactical movement almost impossible in the forested and mountainous border between India and Burma, and both the Allies and Japanese faced severe logistical constraints.
When the rains ceased, the Allies launched two offensives. One, an attack in the coastal Arakan province, failed, with severe effects on Allied morale. This was restored partly by improvements to administration and training, and partly by the much-publicised results of a raid by troops under Brigadier
The effects of this raid may have goaded Japanese commanders into launching their offensives the following year, which failed disastrously.
India and Burma, May - December 1942
Allied and Japanese operations were constrained by terrain and logistics. The frontier region between Burma and India was for the most part almost impassable country, with very few practicable routes through the jungle-clad hills. The Japanese could make use of rail and river transport only as far as the port of
Kalewaon the Chindwin River; the Allies depended on inadequate rail and river links to Dimapurin the Brahmaputra Rivervalley, from where a single road led to the base at Imphal.
The Far Eastern theatre was accorded the lowest priority by the Chiefs of Staff in Britain. British military efforts were instead concentrated on the Middle Eastern theatre, partly in accordance with the declared "Germany First" policy of the United States government under
Franklin Roosevelt. Few resources were allocated to India; and indeed newly raised formations of the British Indian Armywere being trained in desert warfare rather than for jungle warfare, until December 1942, when it was clear that the North African Campaignwas finished to all intents and purposes. [John Masters, "The Road past Mandalay"]
Allied efforts in India were also hampered by the disordered state of Eastern India at the time. In the aftermath of the Allied military disasters in the early months of 1942, there were violent
Quit India movementprotests in Bengal and Bihar, which required large numbers of British troops to suppress. There was also a disastrous famine in Bengal, which may ultimately have led to 3 million deaths through starvation, disease and exposure. Although the immediate cause was a typhoon which devastated large areas in mid-1942, the loss of rice normally imported from Burma and Allied demands for exported rice in other theatres reduced the reserves of food available for relief, while the dislocation caused by sporadic Japanese bombing, and corruption and inefficiency in the government of Bengal prevented any proper distribution of aid, or other drastic measures being taken.
The Japanese were consolidating their position in Burma. Lieutenant General
Shojiro Iida, commander of the Japanese Fifteenth Army, was asked by higher headquarters for his opinion as to whether to resume the offensive after the rains stopped. He in turn consulted the commanders of his forward divisions, who all felt that the logistical problems were too difficult to overcome. Lieutenant General Renya Mutaguchiof the Japanese 18th Division was particularly scathing. Plans for an attack were accordingly dropped.
Within Burma, the Japanese disbanded the Burma Independence Army, which had grown rapidly during the Japanese invasion of Burma, but was only loosely organised and in some cases was opposed to Japanese control, replacing it with the Burma Defence Army, trained by Japanese officers. They also prepared to form a Burmese government, which was eventually established in May, 1943, under
Ba Maw. This government had little real power, and the Japanese remained in control of most aspects of Burma's administration. The Burmese economy, already damaged by the earlier fighting, declined further through damage to the transport infrastructure and lack of commercial markets for exported rice and other products.
Lieutenant General Iida made efforts to promote Burma's interests, but he was repeatedly overruled by directives from Tokyo, and was to be relieved in 1943, partly because he objected to Tokyo's economic policies in Burma. [Allen: "Burma; The longest war", pp. 559-563]
Operations and Plans
First Arakan campaign
In spite of their difficulties, the Allies mounted two operations during the 1942-1943 dry season. The first was a small scale offensive into the coastal Arakan region of Burma. The Indian "Eastern Army" under British General
Noel Irwinintended to reoccupy the Mayu peninsula and Akyab Island, which had an important airfield. Beginning on December 21, 1942, Indian 14th Infantry Division advanced to Donbaik, only a few miles from the end of the peninsula. Here they were halted by a small Japanese force which occupied nearly impregnable bunkers. Indian and British troops made repeated frontal assaults without armoured support, and were thrown back with heavy casualties.
Japanese reinforcements, amounting to an understrength division, arrived from Central Burma. Crossing rivers and mountain ranges which the Allies had declared to be impassable, they hit 14th Division's exposed left flank on
April 3, 1943and overran several units. The division's headquarters was replaced by that of Indian 26th Infantry Division, which attempted to hold a defensive line south of the town of Buthidaung, and even surround the Japanese as they pressed their advantage. 26th Division's exhausted units were unable to hold this line and were forced to abandon much equipment and fall back almost to the Indian frontier.
Irwin was dismissed, partly as a result of this disaster. He made several disparaging remarks regarding the state of equipment, training and morale of Eastern Army. Although not wholly inaccurate, they were widely resented. [Bayly and Harper, "Forgotten Armies", pp. 274-75] Irwin's successor, General
George Giffard, concentrated on restoring the army's administration and morale.
First Chindit expedition
The second action was much more controversial. Under the command of Brigadier
Orde Wingate, the 77th Indian Infantry Brigade, better known as the Chindits, infiltrated through the Japanese front lines and marched deep into Burma with the initial aim of cutting the main north-south railway in Burma. The operation (codenamed Operation "Longcloth") had originally been conceived as part of a much larger coordinated offensive, which had to be aborted due to lack of supplies and shipping. Rather than let the Chindits' training be wasted, Wingate nevertheless carried out the operation, even though its original purpose was invalid.
Some 3,000 men entered Burma in many columns. They did cause damage to the communications of the Japanese in northern Burma cutting the railway for possibly two weeks. However, they suffered heavy casualties; 818 killed, wounded or missing, 27% of the original force. Those that did return were wracked with disease and quite often in dreadful physical condition. Though the operational results can be questioned, the Chindits proved that British and Indian soldiers could live, move and fight as effectively as the Japanese in the jungle, and this aspect of the campaign was used to great propaganda effect, countering the impression created after the battles of early 1942 that the Japanese could not be beaten in the jungle. It was also said by the Japanese commanders after the war that the Japanese in Burma decided later to take the offensive, rather than adopt a purely defensive stance, as a direct result of the Chindit operation.
There was continual patrol activity and low-key fighting on the frontier south of Imphal, but neither army possessed the resources to mount decisive operations.
17th Infantry Division (India)held positions around the town of Tiddimat the end of a precarious supply line, and skirmished with units of the Japanese 33rd Division. The Japanese had a shorter and easier supply line from Kalewa and had the upper hand for most of 1942 and 1943. [William Slim, "Defeat into Victory", p. 284] V Force, an irregular force raised by GHQ India in the frontier areas of Burma and India, also patrolled and scouted in the large areas controlled by neither army, but could have no decisive effect on Japanese operations.
Burma Road and the "Hump"
One of the overriding Allied strategic aims was the maintenance of supplies to the Nationlist Chinese government under
Chiang Kai-Shek. When the Japanese had occupied Burma, the supply route via Rangoon had been cut. The American liaison headquarters under General Joseph Stilwellorganised an airlift of supplies over the Himalayamountain range (the "Hump"). At this stage of the war, the transport aircraft were vulnerable to Japanese fighter aircraft operating from Myitkyinaairfield in northern Burma.. [Allen: "Burma; The longest war", p. 390]
At Stilwell's insistence, the Allies also began construct the
Ledo Roadto link India with China, which was to prove an enormous engineering task. Chinese troops who had retreated into India in 1942 were re-equipped and trained by the Americans, and American logistical units (especially railway operating personnel) improved the Allied supply lines in North Eastern India, in preparation for an offensive from Ledo in 1944.
