orks in 83 PEN. [38] It opens with a preface by
Sun Hsing-yen (largely quoted in this introduction), vindicating
the traditional view of Sun Tzu's life and performances, and
summing up in remarkably concise fashion the evidence in its
favor. This is followed by Ts`ao Kung's preface to his edition,
and the biography of Sun Tzu from the SHIH CHI, both translated
above. Then come, firstly, Cheng Yu-hsien's I SHUO, [39] with
author's preface, and next, a short miscellany of historical and
bibliographical information entitled SUN TZU HSU LU, compiled by
Pi I-hsun. As regards the body of the work, each separate
sentence is followed by a note on the text, if required, and then
by the various commentaries appertaining to it, arranged in
chronological order. These we shall now proceed to discuss
briefly, one by one.

Sun Tzu can boast an exceptionally long distinguished roll
of commentators, which would do honor to any classic. Ou-yang
Hsiu remarks on this fact, though he wrote before the tale was
complete, and rather ingeniously explains it by saying that the
artifices of war, being inexhaustible, must therefore be

extraordinary man, whose biography in the SAN KUO CHIH reads like
a romance. One of the greatest military geniuses that the world
has seen, and Napoleonic in the scale of his operations, he was
especially famed for the marvelous rapidity of his marches, which
has found expression in the line "Talk of Ts`ao Ts`ao, and Ts`ao
Ts`ao will appear." Ou-yang Hsiu says of him that he was a great
captain who "measured his strength against Tung Cho, Lu Pu and
the two Yuan, father and son, and vanquished them all; whereupon
he divided the Empire of Han with Wu and Shu, and made himself
king. It is recorded that whenever a council of war was held by
Wei on the eve of a far-reaching campaign, he had all his
calculations ready; those generals who made use of them did not
lose one battle in ten; those who ran counter to them in any

brevity, are so thoroughly characteristic of the stern commander
