The Art of War by active 6th century B.C. Sunzi

2. _Ssu-ma Fa_, in 1 _chuan_ or 5 chapters. Wrongly attributed to

Ssu-ma Jang-chu of the 6th century B.C. Its date, however, must be early, as the customs of the three ancient dynasties are constantly to be met within its pages. See _Shih Chi_, ch. 64. The _Ssu K’u Ch’uan Shu_ (ch. 99, f. 1) remarks that the oldest three treatises on war, _Sun Tzŭ_, _Wu Tzŭ_ and _Ssu-ma Fa_, are, generally speaking, only concerned with things strictly military—the art of producing, collecting, training and drilling troops, and the correct theory with regard to measures of expediency, laying plans, transport of goods and the handling of soldiers—in strong contrast to later works, in which the science of war is usually blended with metaphysics, divination and magical arts in general.
