Bruce Gudmundsson guides us expertly through the history of the British Expeditionary Force in 1916 as it struggled to become a modern army and turn the tide of the First World War. Examining the tactical innovations that accompanied this change and the conflicting strategies and tactics that it was expected to pursue, Gudmundsson explores the difficulties facing the British Army, including the bewildering number of new technologies in use, from novelties such as combat aircraft, tanks and armoured cars to trench mortars and more than a thousand pieces of siege artillery.
