What went wrong for British forces in 1917? Relive the key battles through first-hand accounts and little-known incidents of World War I. This book offers a fresh, critical history of the 1917 campaign in Flanders. Alan Warren traces the three major battles fought by the British Expeditionary Force in the final months of 1917, from the mines of Messines to the mud of Passchendaele and the tanks at Cambrai. Drawing on a rich array of sources, Warren provides a vivid account of two tragically mismanaged battles, showing that Cambrai further underlined what went wrong for British forces at Passchendaele and thus more fully explains the course of events on the Western front. His compelling narrative history features first-hand accounts, little-known dramatic incidents, and portraits and assessments of the main generals. All readers interested in World War I and the tragic mistakes that led, in the words of Winston Churchill, to “a forlorn expenditure of valour and life without equal in futility” will find this an invaluable military history.
