This book is an operational history of the Canadian Corps in the battles of the final 100 days of World War I, beginning with the battle of Amiens, August 8, 1918, and culminating in the retaking of Mons on November 11, 1918, only hours before the war ended. During the late summer and autumn of 1918, the Canadian Corps, under Lt. Gen. Sir Arthur Currie, played a crucial role in the defeat of the German Army on the Western Front. This work examines the operational, organizational, and tactical innovations developed by the Corps during this campaign and their subsequent effect on military thought. Six battles are examined for their planning, conduct, and lessons: the Battle of Amiens, the breaking of the Drocourt-Queant line, the Canal du Nord and Cambrai, the pursuit to Valenciennes, the storming of Mount Huoy, and the return to Mons.
