This small book by C. R. M. F. Cruttwell contains several lectures delivered in 1936 for the Lees-Knowles Foundation, at Trinity College, Cambridge. Divided into five chapters, the volume examines the role of British strategy in the First World War, considering such themes as the British tradition in continental coalitions, lost opportunities and the war of attrition, and significant points of struggle and achievement during the last phase of the war.
