Art of War

The Art of War is a systematic guide to strategy and tactics for rulers and commanders. The book discusses various maneuvers and the effect of terrain on the outcome of battles. It stresses the importance of accurate information about the enemy's forces, dispositions and deployments, and movements. This is summarized in the axiom "Know the enemy and know yourself, and you can fight a hundred battles with no danger of defeat." It also emphasizes the unpredictability of battle and the use of flexible strategies and tactics. The book's insistence on the close relationship between political considerations and military policy greatly influenced some modern strategists. Mao Zedong and the Chinese communists took from The Art of War many of the tactics they used in fighting the Japanese and, later, the Chinese Nationalists.
