ビルマ国民軍
There were informal contacts between the AFO and the Allies in 1944 and 1945 through the British Force 136. On 27 March 1945, the Burma National Army rose up in a country-wide rebellion against the Japanese. 27 March had been celebrated as 'Resistance Day' until the military renamed it 'Tatmadaw (Armed Forces) Day'. Aung San and others subsequently began negotiations with Lord Mountbatten and officially joined the Allies as the Patriotic Burmese Forces (PBF). At the first meeting, the AFO represented itself to the British as the provisional government of Burma with Thakin Soe as Chairman and Aung San as a member of its ruling committee.
