is normally to keep the peace, and to move his forces only
when occasion requires. He will not use armed force unless
driven to it by necessity.
Many books have I read on the subject of war and
fighting; but the work composed by Sun Wu is the profoundest
of them all. [Sun Tzu was a native of the Ch`i state, his
personal name was Wu. He wrote the ART OF WAR in 13 chapters
for Ho Lu, King of Wu. Its principles were tested on women,
and he was subsequently made a general. He led an army
westwards, crushed the Ch`u state and entered Ying the
capital. In the north, he kept Ch`i and Chin in awe. A
hundred years and more after his time, Sun Pin lived. He was
a descendant of Wu.] [13] In his treatment of deliberation
and planning, the importance of rapidity in taking the field,
[14] clearness of conception, and depth of design, Sun Tzu
stands beyond the reach of carping criticism. My
contemporaries, however, have failed to grasp the full
meaning of his instructions, and while putting into practice
the smaller details in which his work abounds, they have
overlooked its essential purport. That is the motive which
has led me to outline a rough explanation of the whole.

One thing to be noticed in the above is the explicit
statement that the 13 chapters were specially composed for King
Ho Lu. This is supported by the internal evidence of I. ss. 15,
in which it seems clear that some ruler is addressed.
In the bibliographic section of the HAN SHU, there is an
entry which has given rise to much discussion: "The works of Sun
Tzu of Wu in 82 P`IEN (or chapters), with diagrams in 9 CHUAN."
It is evident that this cannot be merely the 13 chapters known to
