The Art of War
by Sun Tzu (page 24 of 33)
23. If fighting is sure to result in victory, then you must fight, even though the ruler forbid it; if fighting will not result in victory, then you must not fight even at the ruler’s bidding.
[Cf. VIII. § 3 fin. Huang Shih-kung of the Ch’in dynasty, who is said to have been the patron of Chang Liang and to have written the San Lueh, has these words attributed to him: "The responsibility of setting an army in motion must devolve on the general alone; if advance and retreat are controlled from the Palace, brilliant results will hardly be achieved. Hence the god-like ruler and the enlightened monarch are content to play a humble part in furthering their country’s cause [lit., kneel down to push the chariot wheel]." This means that "in matters lying outside the zenana, the decision of the military commander must be absolute." Chang Yu also quote the saying: "Decrees from the Son of Heaven do not penetrate the walls of a camp."]
24. The general who advances without coveting fame and retreats without fearing disgrace,
[It was Wellington, I think, who said that the hardest thing of all for a soldier is to retreat.]
whose only thought is to protect his country and do good service for his sovereign, is the jewel of the kingdom.
[A noble presentiment, in few words, of the Chinese "happy warrior." Such a man, says Ho Shih, "even if he had to suffer punishment, would not regret his conduct."]
25. Regard your soldiers as your children, and they will follow you into the deepest valleys; look on them as your own beloved sons, and they will stand by you even unto death.
[Cf. I. § 6. In this connection, Tu Mu draws for us an engaging picture of the famous general Wu Ch’i, from whose treatise on war I have frequently had occasion to quote: "He wore the same clothes and ate the same food as the meanest of his soldiers, refused to have either a horse to ride or a mat to sleep on, carried his own surplus rations wrapped in a parcel, and shared every hardship with his men. One of his soldiers was suffering from an abscess, and Wu Ch’i himself sucked out the virus. The soldier’s mother, hearing this, began wailing and lamenting. Somebody asked her, saying: ‘Why do you cry? Your son is only a common soldier, and yet the commander-in-chief himself has sucked the poison from his sore.’ The woman replied, ‘Many years ago, Lord Wu performed a similar service for my husband, who never left him afterwards, and finally met his death at the hands of the enemy. And now that he has done the same for my son, he too will fall fighting I know not where.’" Li Ch’uan mentions the Viscount of Ch’u, who invaded the small state of Hsiao during the winter. The Duke of Shen said to him: "Many of the soldiers are suffering severely from the cold." So he made a round of the whole army, comforting and encouraging the men; and straightway they felt as if they were clothed in garments lined with floss silk.]
26. If, however, you are indulgent, but unable to make your authority felt; kind-hearted, but unable to enforce your commands; and incapable, moreover, of quelling disorder: then your soldiers must be likened to spoilt children; they are useless for any practical purpose.
[Li Ching once said that if you could make your soldiers afraid of you, they would not be afraid of the enemy. Tu Mu recalls an instance of stern military discipline which occurred in 219 A.D., when Lu Meng was occupying the town of Chiang-ling. He had given stringent orders to his army not to molest the inhabitants nor take anything from them by force. Nevertheless, a certain officer serving under his banner, who happened to be a fellow-townsman, ventured to appropriate a bamboo hat belonging to one of the people, in order to wear it over his regulation helmet as a protection against the rain. Lu Meng considered that the fact of his being also a native of Ju-nan should not be allowed to palliate a clear breach of discipline, and accordingly he ordered his summary execution, the tears rolling down his face, however, as he did so. This act of severity filled the army with wholesome awe, and from that time forth even articles dropped in the highway were not picked up.]
27. If we know that our own men are in a condition to attack, but are unaware that the enemy is not open to attack, we have gone only halfway towards victory.
[That is, Ts’ao Kung says, "the issue in this case is uncertain."]
28. If we know that the enemy is open to attack, but are unaware that our own men are not in a condition to attack, we have gone only halfway towards victory.
[Cf. III. § 13 (1).]
29. If we know that the enemy is open to attack, and also know that our men are in a condition to attack, but are unaware that the nature of the ground makes fighting impracticable, we have still gone only halfway towards victory.
30. Hence the experienced soldier, once in motion, is never bewildered; once he has broken camp, he is never at a loss.
[The reason being, according to Tu Mu, that he has taken his measures so thoroughly as to ensure victory beforehand. "He does not move recklessly," says Chang Yu, "so that when he does move, he makes no mistakes."]
31. Hence the saying: If you know the enemy and know yourself, your victory will not stand in doubt; if you know Heaven and know Earth, you may make your victory complete.
[Li Ch’uan sums up as follows: "Given a knowledge of three things—the affairs of men, the seasons of heaven and the natural advantages of earth—, victory will invariably crown your battles."]

Chapter XI. THE NINE SITUATIONS
1. Sun Tzŭ said: The art of war recognises nine varieties of ground: (1) Dispersive ground; (2) facile ground; (3) contentious ground; (4) open ground; (5) ground of intersecting highways; (6) serious ground; (7) difficult ground; (8) hemmed-in ground; (9) desperate ground.
2. When a chieftain is fighting in his own territory, it is dispersive ground.
[So called because the soldiers, being near to their homes and anxious to see their wives and children, are likely to seize the opportunity afforded by a battle and scatter in every direction. "In their advance," observes Tu Mu, "they will lack the valor of desperation, and when they retreat, they will find harbors of refuge."]
3. When he has penetrated into hostile territory, but to no great distance, it is facile ground.
[Li Ch’uan and Ho Shih say "because of the facility for retreating," and the other commentators give similar explanations. Tu Mu remarks: "When your army has crossed the border, you should burn your boats and bridges, in order to make it clear to everybody that you have no hankering after home."]
4. Ground the possession of which imports great advantage to either side, is contentious ground.
[Tu Mu defines the ground as ground "to be contended for." Ts’ao Kung says: "ground on which the few and the weak can defeat the many and the strong," such as "the neck of a pass," instanced by Li Ch’uan. Thus, Thermopylae was of this classification because the possession of it, even for a few days only, meant holding the entire invading army in check and thus gaining invaluable time. Cf. Wu Tzŭ, ch. V. ad init.: "For those who have to fight in the ratio of one to ten, there is nothing better than a narrow pass." When Lu Kuang was returning from his triumphant expedition to Turkestan in 385 A.D., and had got as far as I-ho, laden with spoils, Liang Hsi, administrator of Liang-chou, taking advantage of the death of Fu Chien, King of Ch’in, plotted against him and was for barring his way into the province. Yang Han, governor of Kao-ch’ang, counseled him, saying: "Lu Kuang is fresh from his victories in the west, and his soldiers are vigorous and mettlesome. If we oppose him in the shifting sands of the desert, we shall be no match for him, and we must therefore try a different plan. Let us hasten to occupy the defile at the mouth of the Kao-wu pass, thus cutting him off from supplies of water, and when his troops are prostrated with thirst, we can dictate our own terms without moving. Or if you think that the pass I mention is too far off, we could make a stand against him at the I-wu pass, which is nearer. The cunning and resource of Tzŭ-fang himself would be expended in vain against the enormous strength of these two positions." Liang Hsi, refusing to act on this advice, was overwhelmed and swept away by the invader.]
5. Ground on which each side has liberty of movement is open ground.
[There are various interpretations of the Chinese adjective for this type of ground. Ts’ao Kung says it means "ground covered with a network of roads," like a chessboard. Ho Shih suggested: "ground on which intercommunication is easy."]
6. Ground which forms the key to three contiguous states,
[Ts’au Kung defines this as: "Our country adjoining the enemy’s and a third country conterminous with both." Meng Shih instances the small principality of Cheng, which was bounded on the north-east by Ch’i, on the west by Chin, and on the south by Ch’u.]
