Although the Congress had conditionally supported the Allied war effort, following failure of the Cripps mission, the Quit India Movement was launched in India on 8 August 1942 that called for the British Raj to leave India or face a massive Civil Disobedience. Forewarned, the Raj quickly arrested the Congress leadership. However, foreplanning on the part of the Congress meant the movement continued at the local level, and quickly deteriorated into a leaderless act of defiance and descended into violence and general anarchy and mayhem. The movement created alarm amongst the high-command and significantly hindered the Allied war effort.
