An excellent and scholarly survey of the principles of simulated warfare, with four board games, including a simple game of medieval warfare during the Hundred Years War, a grand Napoleonic campaign game, a cat and mouse wargame of WWII espionage and airpower during the last days of the battleship Tirpitz, and a thoughtful examination of the psychology of battle in the form of a WWII Pacific Theater role-playing game of personal man-to-man combat.
