A continuation of the massive official history of Britain's part in the campaigns of Western Europe during World War I, based on documents and prepared under the direction of the Historical Section of the Committee of Imperial Defense by a panel of military historians. The first of the two volumes mentioned deals with the period from June 7 to November 10 (Messines and Passchendaele) and is edited by Brigadier-General Sir James E. Edmonds; the second, compiled by Captain Wilfrid Miles, treats the Battle of Cambrai of the late fall of 1917.
