The Art of War

The answer was again in the affirmative, so arrangements were made to bring 180 ladies out of the Palace. Sun Tzŭ divided them into two companies, and placed one of the King’s favourite concubines at the head of each. He then bade them all take spears in their hands, and addressed them thus: "I presume you know the difference between front and back, right hand and left hand?"

Sun Tzŭ went on: "When I say "Eyes front," you must look straight ahead. When I say "Left turn," you must face towards your left hand. When I say "Right turn," you must face towards your right hand. When I say "About turn," you must face right round towards your back."

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 Tzŭ 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 Tzŭ: "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 favourite concubines were about to be executed, he was greatly alarmed and hurriedly 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."

Accordingly, he had the two leaders beheaded, and straightway 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 evolutions, turning to the right or to the left, marching ahead or wheeling back, kneeling or standing, with perfect accuracy and precision, not venturing to utter a sound. Then Sun Tzŭ 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, and they will not disobey."

After that, Ho Lu saw that Sun Tzŭ 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 spread his fame abroad amongst the feudal princes. And Sun Tzŭ shared in the might of the King.

About Sun Tzŭ 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 of his time. The historian speaks of him too as Sun Tzŭ, and in his preface we read: "Sun Tzŭ had his feet cut off and yet continued to discuss the art of war." [3] 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. § 19, note.

In the third year of his reign [512 B.C.] Ho Lu, king of Wu, took the field with Tzŭ-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 B.C.], King Ho Lu addressed Wu Tzŭ-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 Tzŭ-ch’ang, [4] 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 succeed." Ho Lu followed this advice, [beat Ch’u in five pitched battles and marched into Ying.] [5]

From this time onward, a number of famous soldiers arose, one after the other: Kao-fan, [7] who was employed by the Chin State; Wang-tzu, [8] 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 necessary, therefore, to say much of such a work as the Wu Yüeh Ch’un Ch’iu, which is supposed to have been written by Chao Yeh of the 1st century A.D. 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 Tzŭ will be found, for what it is worth, in chapter 2. The only new points in it worth noting are: (1) Sun Tzŭ was first recommended to Ho Lu by Wu Tzŭ-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 Tzŭ: "When sovereign and ministers show perversity of mind, it is impossible even for a Sun Tzŭ to encounter the foe." Assuming that this work is genuine (and hitherto no doubt has been cast upon it), we have here the earliest direct reference for Sun Tzŭ, for Huai-nan Tzŭ died in 122 B.C., many years before the Shih Chi was given to the world.

Teng Ming-shih informs us that the surname "Sun" was bestowed on Sun Wu’s grandfather by Duke Ching of Ch’i [547-490 B.C.]. Sun Wu’s father Sun P’ing, rose to be a Minister of State in Ch’i, and Sun Wu himself, whose style was Ch’ang-ch’ing, fled to Wu on account of the rebellion which was being fomented by the kindred of T’ien Pao. He had three sons, of whom the second, named Ming, was the father of Sun Pin. According to this account then, Pin was the grandson of Wu, which, considering that Sun Pin’s victory over Wei was gained in 341 B.C., may be dismissed as chronologically impossible. Whence these data were obtained by Teng Ming-shih I do not know, but of course no reliance whatever can be placed in them.

I have heard that the ancients used bows and arrows to their advantage. [10] The Lun Yu says: “There must be a sufficiency of military strength.” The Shu Ching mentions "the army" among the "eight objects of government." The I Ching says: "‘army’ indicates firmness and justice; the experienced leader will have good fortune." The Shih Ching says: "The King rose majestic in his wrath, and he marshalled his troops." The Yellow Emperor, T’ang the Completer and Wu Wang all used spears and battle-axes in order to succour their generation. The Ssu-ma Fa says: "If one man slay another of set purpose, he himself may rightfully be slain." He who relies solely on warlike measures shall be exterminated; he who relies solely on peaceful measures shall perish. Instances of this are Fu Ch’ai [11] on the one hand and Yen Wang on the other. [12] In military matters, the Sage’s rule 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 Tzŭ 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 Tzŭ 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.

In the bibliographic section of the Han Shu, there is an entry which has given rise to much discussion: "The works of Sun Tzŭ 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 Ssu-ma Ch’ien, or those we possess today. Chang Shou-chieh refers to an edition of Sun Tzŭ’s Art of War of which the "13 chapters" formed the first chuan, adding that there were two other chuan besides. This has brought forth a theory, that the bulk of these 82 chapters consisted of other writings of Sun Tzŭ—we should call them apocryphal—similar to the Wen Ta, of which a specimen dealing with the Nine Situations [15] is preserved in the T’ung Tien, and another in Ho Shin’s commentary. It is suggested that before his interview with Ho Lu, Sun Tzŭ had only written the 13 chapters, but afterwards composed a sort of exegesis in the form of question and answer between himself and the King. Pi I-hsun, the author of the Sun Tzŭ Hsu Lu, backs this up with a quotation from the Wu Yüeh Ch’un Ch’iu: "The King of Wu summoned Sun Tzŭ, and asked him questions about the art of war. Each time he set forth a chapter of his work, the King could not find words enough to praise him." As he points out, if the whole work was expounded on the same scale as in the above-mentioned fragments, the total number of chapters could not fail to be considerable. Then the numerous other treatises attributed to Sun Tzŭ might be included.

The fact that the Han Chih mentions no work of Sun Tzŭ except the 82 p’ien, whereas the Sui and T’ang bibliographies give the titles of others in addition to the "13 chapters," is good proof, Pi I-hsun thinks, that all of these were contained in the 82 p’ien. Without pinning our faith to the accuracy of details supplied by the Wu Yüeh Ch’un Ch’iu, or admitting the genuineness of any of the treatises cited by Pi I-hsun, we may see in this theory a probable solution of the mystery. Between Ssu-ma Ch’ien and Pan Ku there was plenty of time for a luxuriant crop of forgeries to have grown up under the magic name of Sun Tzŭ, and the 82 p’ien may very well represent a collected edition of these lumped together with the original work. It is also possible, though less likely, that some of them existed in the time of the earlier historian and were purposely ignored by him. [16]

Tu Mu’s conjecture seems to be based on a passage which states: "Wei Wu Ti strung together Sun Wu’s Art of War," which in turn may have resulted from a misunderstanding of the final words of Ts’ao King’s preface. This, as Sun Hsing-yen points out, is only a modest way of saying that he made an explanatory paraphrase, or in other words, wrote a commentary on it. On the whole, this theory has met with very little acceptance. Thus, the Ssu K’u Ch’uan Shu says: "The mention of the 13 chapters in the Shih Chi shows that they were in existence before the Han Chih, and that latter accretions are not to be considered part of the original work. Tu Mu’s assertion can certainly not be taken as proof."

There is every reason to suppose, then, that the 13 chapters existed in the time of Ssu-ma Ch’ien practically as we have them now. That the work was then well known he tells us in so many words. "Sun Tzŭ’s 13 Chapters and Wu Ch’i’s Art of War are the two books that people commonly refer to on the subject of military matters. Both of them are widely distributed, so I will not discuss them here." But as we go further back, serious difficulties begin to arise. The salient fact which has to be faced is that the Tso Chuan, the greatest contemporary record, makes no mention whatsoever of Sun Wu, either as a general or as a writer. It is natural, in view of this awkward circumstance, that many scholars should not only cast doubt on the story of Sun Wu as given in the Shih Chi, but even show themselves frankly skeptical as to the existence of the man at all. The most powerful presentment of this side of the case is to be found in the following disposition by Yeh Shui-hsin: [17]—

It is stated in Ssu-ma Ch’ien’s history that Sun Wu was a native of the Ch’i State, and employed by Wu; and that in the reign of Ho Lu he crushed Ch’u, entered Ying, and was a great general. But in Tso’s Commentary no Sun Wu appears at all. It is true that Tso’s Commentary need not contain absolutely everything that other histories contain. But Tso has not omitted to mention vulgar plebeians and hireling ruffians such as Ying K’ao-shu, [18] Ts’ao Kuei, [19], Chu Chih-wu and Chuan She-chu [20]. In the case of Sun Wu, whose fame and achievements were so brilliant, the omission is much more glaring. Again, details are given, in their due order, about his contemporaries Wu Yuan and the Minister P’ei. [21] Is it credible that Sun Wu alone should have been passed over?

In point of literary style, Sun Tzŭ’s work belongs to the same school as Kuan Tzŭ, [22] Liu T’ao, [23] and the Yüeh Yu [24] and may have been the production of some private scholar living towards the end of the "Spring and Autumn" or the beginning of the "Warring States" period. [25] The story that his precepts were actually applied by the Wu State, is merely the outcome of big talk on the part of his followers.

From the flourishing period of the Chou dynasty [26] down to the time of the "Spring and Autumn," all military commanders were statesmen as well, and the class of professional generals, for conducting external campaigns, did not then exist. It was not until the period of the "Six States" [27] that this custom changed. Now although Wu was an uncivilized State, it is conceivable that Tso should have left unrecorded the fact that Sun Wu was a great general and yet held no civil office? What we are told, therefore, about Jang-chu [28] and Sun Wu, is not authentic matter, but the reckless fabrication of theorizing pundits. The story of Ho Lu’s experiment on the women, in particular, is utterly preposterous and incredible.

Yeh Shui-hsin represents Ssu-ma Ch’ien as having said that Sun Wu crushed Ch’u and entered Ying. This is not quite correct. No doubt the impression left on the reader’s mind is that he at least shared in these exploits. The fact may or may not be significant; but it is nowhere explicitly stated in the Shih Chi either that Sun Tzŭ was general on the occasion of the taking of Ying, or that he even went there at all. Moreover, as we know that Wu Yuan and Po P’ei both took part in the expedition, and also that its success was largely due to the dash and enterprise of Fu Kai, Ho Lu’s younger brother, it is not easy to see how yet another general could have played a very prominent part in the same campaign.
