New York, 1st US ed., 1972. 284 pp., 20 photo-ills., + 23 maps. D.j., fore-edge uncut; 21 x 15cm. V.G.+. Military men ' and military historians ' have not ceased to debate whether tanks are effective, efficient machines of war. Those best known in the history of tank warfare ' General Fuller, Sir Basil Liddell Hart, Patton, Guderian ' changed their minds often. This book is the definitive history of the policy-makers and the strategists who talked tanks. Perhaps even more important, it is the story of tank warfare itself ' the split-second decisions, the battle-weary tank crews, the mud. Although the use of tank-like vehicles was envisioned long before World War I, it was during that war to end all wars that tanks became a fact of modern military life and strategy. Macksey gives the reader a clear understanding of the technical and tactical development of these "ungainly monsters" which were originally seen as armoured horses but which later, as the spearhead of the German blitzkrieg, came to be recognised as the key component in the mechanized land army's need for mobility and strategic flexibility.
