Burma National Army
The fall of Mandalay also precipitated the change of sides by the Burma National Army and open rebellion against the Japanese by other underground movements belonging to the Anti-Fascist Organisation. In the last week of March Aung San, commander-in-chief of the Burma National Army, appeared in public in Burmese native dress instead of Japanese uniform. Shortly afterwards, most of the Burma National Army paraded in Rangoon and then marched out of the city as if going to the front in Central Burma. They then rebelled against the Japanese on 27 March.
