General Sir Arthur William Currie, was a senior officer of the Canadian Army who fought during World War I. He had the unique distinction of starting his military career on the very bottom rung as a pre-war militia gunner before rising through the ranks to become the first Canadian commander of the Canadian Corps. Currie's success was based on his ability to rapidly adapt brigade tactics to the exigencies of trench warfare, using set piece operations and bite-and-hold tactics. He is generally considered to be among the most capable commanders of the Western Front, and one of the finest commanders in Canadian military history.

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.
