Selarang Barracks incident

The Selarang Barracks incident, also known as the Barrack Square incident or the Selarang Square Squeeze, was a revolt of British and Australian prisoners-of-war (POWs) interned in a Japanese camp in Changi, Singapore. The events started on 30 August 1942 after the Japanese recaptured four POWs who escaped from the Selarang Barracks camps, and required that the other prisoners sign a pledge not to escape.
