Burma Campaign 1942–45: Retreat, Chindits, Kohima, Imphal & Fourteenth Army — Complete Field Guide

Burma began with one of the longest retreats in British military history and ended with Fourteenth Army advancing back to Rangoon.

The campaign involved British, Indian, African, Gurkha, Burmese, Chinese and American forces across some of the most demanding terrain of the Second World War.

1942: retreat

Japanese forces invaded Burma after their successes in Malaya. British Imperial forces withdrew toward India through heat, jungle, monsoon and collapsing communications.

Learning jungle warfare

Early Allied formations were often poorly prepared for Japanese infiltration tactics and jungle movement. Training, organisation and medical systems changed substantially over the next two years.

Chindits

Orde Wingate's long-range penetration groups operated behind Japanese lines in 1943 and 1944. Air supply allowed deep operations, but casualties from combat, disease and exhaustion were severe.

Imphal and Kohima

Japan's 1944 U-Go offensive into India culminated in defeat at Imphal and Kohima. Gallus already covers those battles in a dedicated guide. Air supply and increasingly effective Allied infantry tactics helped turn the Japanese advance into a disaster.

Slim and Fourteenth Army

General William Slim's Fourteenth Army emphasised realistic training, morale, logistics and the ability of surrounded units to hold while supplied from the air. Those methods shaped the 1944–45 advance.

Meiktila and Mandalay

In 1945, mobile operations across central Burma captured Meiktila and Mandalay, disrupting Japanese communications and opening the route south.

Rangoon

Allied forces captured Rangoon in May 1945 before the monsoon fully closed the campaign season.
