1st Division, Canadian Expeditionary Force (CEF) was the first division ever put in the field by the Dominion of Canada. In this book, detailed studies are made of training methods, unit organization, equipment, staff duties and procedures, and personnel problems. There are copious references to research documents and an extensive bibliography for each chapter. The primary focus of this study is the infantry, examining the work of individual units and their commanders, noting the improvement in staff duties as the war progressed. It also examines the substantial British contribution to Canadian skill at arms. Staff officers were with few exceptions British, since Canada had almost no trained staff officers at the beginning of the war, and only a few even at the end. The final chapters show how all the training, staff work, organizational changes and team work came together in 1918 during the battle of Amiens, Canal du Nord and the final offensive.
