Book excerpt: This fully illustrated WWI battlefield guide provides essential historical context and visitor information for exploring this site on the Western Front. Located near the Belgian border, the French town of Cambrai was a vital supply point for the German forces along the Hindenburg Line. It is best known for the First Battle of Cambria, an epic tank battle which took place there in 1917. Although the British Expeditionary Force were successful in the first day of combat, the tables soon turned. As on other occasions throughout the War, the area changed hands many times. Illustrated with then and now pictures, this book presents a detailed overview of the battle from multiple perspectives. It then provides five walking tour itineraries taking readers through the La Vacquerie Battlefield, Bonavis Farm, Les Rues Vertes, Bapaume, and more.
