The map shows the divisional boundary line for the 3rd Canadian Infantry Division and their planned northwest axis of attack towards the Canal de Nord on Sept. 27, 1918. The Canadian Corps assault on the Canal de Nord was a critical component of the Allied offensive that led to the capture of the city of Cambrai and the breaking of the German Hindenburg Line. The Allies’ hundred days offensive would lead to the German surrender on November 11, 1918 and the end of World War One.
