[1][2] The residents of Camp 30 were mostly Germans captured by the British and sent to Canada for internment in anticipation of a potential invasion of Britain.
The violence began after 126 prisoners were sent to another camp to be shackled as a reprisal for the chaining of Canadian soldiers captured at Dieppe (itself a reaction to captured plans for the shackling of German POWs[3]).
After a period of hand-to-hand fighting, during which one Canadian guard had his skull fractured, 400 prisoners barricaded themselves in a hall.
A group of students at a nearby commando course in Kingston, Ontario arrived on Canadian Thanksgiving, subduing the barricaded prisoners with fire hoses and tear gas.
[4] A number of other prisoners and guards were injured during the revolt, often in hand-to-hand combat.
