Written by a former Harvard professor of decision science and game theory this book presents original insights on the strategies and tactics undertaken in four major battles of the Second World War. That the fighting at Gazala in Libya in the late spring of 1942 constituted what has been called probably the most spectacular series of victories ever gained over a British army was in part due to its having violated the gametheoretic ZeroSum Maxim of Napoleon Do not do what your enemy wishes you to. The sensational British reversal of that disaster later that year at El Alamein in Egypt derived largely from heeding the millenniaold military priority of command unity which has been analyzed and reendorsed by modern decision science.
