The volume surveys major military and political developments of the Great War, beginning with Canada's rapid mobilization and battlefield achievements, including Vimy Ridge and actions at Ypres, and accounts of wartime atrocities used to illustrate enemy tactics. It examines aerial and submarine campaigns such as Zeppelin raids and merchant sinkings, traces political upheaval in Russia from the revolution to Bolshevik ascendancy, and describes Allied and American mobilization, training, and adaptation. It also assesses logistics and civilian contributions—particularly food production and supply measures—that influenced the conflict's course, combining campaign narratives with analysis of technology, diplomacy, and social responses to total war.
