 Prior to the Dutch Politionele acties ("police action"), there was an ultimatum for the Indonesian combatants in Bandung to leave, given by the British military command, that temporarily (before the Dutch came back) tried to restore order.As for the answer, on March 24, 1946, the southern part of Bandung was deliberately burned down as they were leaving.This event is known as "Bandung Lautan Api" or "Bandung as the sea of flame".
