" Again the girls assented. The words of command having been thus explained, he set up the halberds and battle-axes in order to begin the drill. Then, to the sound of drums, he gave the order "Right turn." But the girls only burst out laughing. Sun Tzu said: "If words of command are not clear and distinct, if orders are not thoroughly understood, then the general is to blame."
So he started drilling them again, and this time gave the order "Left turn," whereupon the girls once more burst into fits of laughter. Sun Tzu: "If words of command are not clear and distinct, if orders are not thoroughly understood, the general is to blame. But if his orders ARE clear, and the soldiers nevertheless disobey, then it is the fault of their officers."
So saying, he ordered the leaders of the two companies to be beheaded. Now the king of Wu was watching the scene from the top of a raised pavilion; and when he saw that his favorite concubines were about to be executed, he was greatly alarmed and hurried ly sent down the following message: "We are now quite satisfied as to our general's ability to handle troops. If we are bereft of these two concubines, our meat and drink will lose their savor. It is our wish that they shall not be beheaded."
Sun Tzu replied: "Having once received His Majesty's commission to be the general of his forces, there are certain commands of His Majesty which, acting in that capacity, I am unable to accept." Accordingly, he had the two leaders beheaded, and straig htway installed the pair next in order as leaders in their place. When this had been done, the drum was sounded for the drill once more; and the girls went through all the evolution, turning to the right or to the left, marching ahead or wheeling back, k neeling or standing, with perfect accuracy and precision, not venturing to utter a sound.
Then Sun Tzu sent a messenger to the King saying: "Your soldiers, Sire, are now properly drilled and disciplined, and ready for your majesty's inspection. They can be put to any use that their sovereign may desire; bid them go through fire and water, an d they will not disobey."
But the King replied: "Let our general cease drilling and return to camp. As for us, We have no wish to come down and inspect the troops." Thereupon Sun Tzu said: "The King is only fond of words, and cannot translate them into deeds." After that, Ho Lu saw that Sun Tzu was one who knew how to handle an army, and finally appointed him general. In the west, he defeated the Ch`u State and forced his way into Ying, the capital; to the north he put fear into the States of Ch`i and Chin, and spre ad his fame abroad amongst the feudal princes. And Sun Tzu shared in the might of the King.
About Sun Tzu himself this is all that Ssu-ma Ch`ien has to tell us in this chapter. But he proceeds to give a biography of his descendant, Sun Pin, born about a hundred years after his famous ancestor's death, and also the outstanding military genius o f his time. The historian speaks of him too as Sun Tzu, and in his preface we read: "Sun Tzu had his feet cut off and yet continued to discuss the art of war. "  It seems likely, then, that "Pin" was a nickname bestowed on him after his mutilation, unless the story was invented in order to account for the name. The crowning incident of his career, the crushing defeat of his treacherous rival P`ang Chuan, will be found briefly related in Chapter V. ss. 19, note.
To return to the elder Sun Tzu. He is mentioned in two other passages of the SHIH CHI: In the third year of his reign [512 BC] Ho Lu, king of Wu, took the field with Tzu-hsu [i.e. Wu Yuan] and Po P`ei, and attacked Ch`u. He captured the town of Shu and slew the two prince's sons who had formerly been generals of Wu. He was then meditating a descent on Ying [the capital]; but the general Sun Wu said: "The army is exhausted. It is not yet possible. We must wait" . [After further successful fighting ,] "in the ninth year [506 BC], King Ho Lu addressed Wu Tzu-hsu and Sun Wu, saying: "Formerly, you declared that it was not yet possible for us to enter Ying. Is the time ripe now?"
The two men replied: "Ch`u's general Tzu-ch`ang,  is grasping and covetous, and the princes of T`ang and Ts`ai both have a grudge against him. If Your Majesty has resolved to make a grand attack, you must win over T`ang and Ts`ai, and then you may s ucceed." Ho Lu followed this advice, [beat Ch`u in five pitched battles and marched into Ying.] 
This is the latest date at which anything is recorded of Sun Wu. He does not appear to have survived his patron, who died from the effects of a wound in 496.
In another chapter there occurs this passage:  -- From this time onward, a number of famous soldiers arose, one after the other: Kao-fan,  who was employed by the Chin State; Wang-tzu,  in the service of Ch`i; and Sun Wu, in the service of Wu. These men developed and threw light upon the principles of war.
It is obvious enough that Ssu-ma Ch`ien at least had no doubt about the reality of Sun Wu as an historical personage; and with one exception, to be noticed presently, he is by far the most important authority on the period in question. It will not be nec essary, therefore, to say much of such a work as the WU YUEH CH`UN CH`IU, which is supposed to have been written by Chao Yeh of the 1st century AD
The attribution is somewhat doubtful; but even if it were otherwise, his account would be of little value, based as it is on the SHIH CHI and expanded with romantic details. The story of Sun Tzu will be found, for what it is worth, in chapter 2. The onl y new points in it worth noting are: (1) Sun Tzu was first recommended to Ho Lu by Wu Tzu-hsu. (2) He is called a native of Wu. (3) He had previously lived a retired life, and his contemporaries were unaware of his ability.
The following passage occurs in the Huai-nan Tzu: "When sovereign and ministers show perversity of mind, it is impossible even for a Sun Tzu to encounter the foe.
