12 September 1945. While its troops may remain intact and under British command until disarmament terms are negotiated, SEAC declares that the MPAJA is no longer operational after 12 September.

Henceforth, a number of guerrillas are arrested for extra-judicial killings.
12 September 1945. The remnants of the once-vast Japanese forces in Burma formally surrender to the Allies; about 70,000 troops are taken prisoner. Since the disastrous failure of the main Japanese army in July to break out of Burma, its few survivors together with other detachments (including units of the Indian National Army) have struggled to retreat east into Thailand or south into Malaya. Many have been killed by Karen irregulars.
