The Battle of Cambrai, 1918 was fought between troops of the British First, Third and Fourth Armies and German Empire forces during the Hundred Days Offensive of the First World War. The battle took place in and around the French city of Cambrai, between 8 and 10 October 1918. The battle incorporated many of the newer tactics of 1918, in particular tanks. The battle witnessed over 300 tanks taking part, gaining considerable ground in less than 36 hours, with about 2,000 more British casualties than German, which was light relative to earlier phases of the war.

The Canadian Corps was a World War I corps formed from the Canadian Expeditionary Force in September 1915 after the arrival of the 2nd Canadian Division in France. The corps was expanded by the addition of the 3rd Canadian Division in December 1915 and the 4th Canadian Division in August 1916. The organization of a 5th Canadian Division began in February 1917 but it was still not fully formed when it was broken up in February 1918 and its men used to reinforce the other four divisions.
