Pre-war situation

Before the Second World War broke out, Burma was part of the British Empire, having been progressively occupied and annexed following three Anglo-Burmese Wars in the nineteenth century. Initially governed as part of British India, Burma was formed into a separate colony under the Government of India Act 1935
Government of India Act 1935
The Government of India Act 1935 was originally passed in August 1935 , and is said to have been the longest Act of Parliament ever enacted by that time. Because of its length, the Act was retroactively split by the Government of India Act 1935 into two separate Acts:# The Government of India...

 community was becoming increasingly restive. Among their concerns were the importation of Indian workers to provide a labour force for many of the new industries, and the erosion of traditional society in the countryside as land was used for plantations of export crops or became mortgaged to Indian moneylenders. Pressure for independence was growing. When Burma came under attack, the Bamar were unwilling to contribute to the defence of the British establishment, and many readily joined movements which aided the Japanese.

Japanese plans

Japan entered the war primarily to obtain raw materials, especially oil, from European (particularly Dutch) possessions in South East Asia which were weakly defended because of the war in Europe. Their plans involved an attack on Burma partly because of Burma's own natural resources (which included some oil from fields around Yenangyaung

 in Tenasserim. The airfields were difficult to defend and reinforce, but Burma Army HQ had been ordered to hold these outposts because of their importance to the defence of Malaya. The Japanese forced their way over the steep jungle-covered Tenasserim Range, and attacked Tavoy on 18 January. The defenders, the 3rd and 6th battalions of the Burma Rifles, were overwhelmed and forced to evacuate the town in disorder. Mergui was evacuated before it was attacked.

Rangoon was initially defended relatively successfully against Japanese air raids, by small RAF detachments reinforced by a squadron of the American Volunteer Group

, better known as the "Flying Tigers". The majority of the airfields were between Rangoon and the Axis advance and as the Japanese gained use of the airfields in Tenasserim, the amount of warning the Rangoon airfields could get of attack decreased, and they became more and more untenable.

On 22 January 1942, the main body of the Japanese 55th Division began the main attack westward from Rahaeng in Thailand across the Kawkareik

The 2nd Burma Brigade was squeezed into a progressively tighter perimeter, and eventually retreated over river by ferry on 31 January after abandoning a large amount of supplies and equipment. Part of the force was left behind in Moulmein and had to swim the river.

The Sittang Bridge

The 17th Indian Division fell back northward. They attempted to hold the Bilin River and other fallback lines as they did so, but had too few troops to avoid being continually outflanked. The division eventually retreated toward the bridge over the Sittang River

 in general disorder. The retreat was delayed by incidents such as a vehicle breaking through the bridge deck, air attacks (including, allegedly, accidental attacks by the RAF and AVG) and Japanese harassment. The delays allowed Japanese parties to infiltrate to the bridge itself, and the poorly organised defence of the bridge was in danger of collapsing. Fearing that the bridge would fall intact to the Japanese who would use it to advance on Rangoon, the divisional commander, Major-General "Jackie" Smyth, VC

, ordered it to be blown up on the morning of 23 February 1942, with most of the division stranded on the enemy-held side.

Many of the men of the 17th Division who were trapped on the Japanese-held side of the river made their way across to the west bank by swimming or on improvised rafts, but had to abandon almost all their equipment, including most of their small arms. This later led some to question the decision to blow the bridge, arguing that the river itself did not offer much of an obstacle to the Japanese, and that more harm than good was achieved, as it resulted in the stranding of two brigades and delayed the Japanese capture of Rangoon by ten days at most.

Had he not done so, the Japanese might have captured General Alexander and much of the rest of Burma Army.

Supplies were not immediately a problem, as much war material (including material originally meant for shipment to China) had been evacuated from Rangoon, rice was plentiful and the oilfields in central Burma were still intact, but no proper land routes from India existed and only the recapture of Rangoon would allow the Allies to hold Burma indefinitely.

The Allies hoped that the Japanese advance would slow down; instead, it gained speed. The Japanese reinforced their two divisions in Burma with one transferred from Malaya
