1st ed., 1967. 243 pp., various maps, plans & photo-plates. D.j., 22 x 14cm. V.G. Cutting tipped-in. The Battle of Cambrai began on November 20th, 1917. Without warning 378 monster tanks lumbered out of their hiding places behind the British lines and headed towards the impregnable German defences of the Hindenburg Line. It was the first great tank battle in history and behind them marched six infantry divisions, including the feared 51st Highland Territorials. Massed in the rear, waiting to take advantage of any breakthrough, were five divisions of cavalry. This book gives an account of how, for the first time since the two opposing armies had become deadlocked in the trenches of the Western Front, the Hindenburg Line was broken and in a matter of hours the Third Army of the B.E.F. had advanced and accomplished more than any other single operation of the war thus far. It vividly describes the Battle of Cambrai through the eyes of those who took part. It traces the events that made the tank possible, and the efforts of a small band of pioneers responsible for what was perhaps the most important invention of the First World War and a major factor in the final victory.
