but a power of estimating the adversary,
A general should always utilise, but never rely wholly on natural advantages of terrain.
of controlling the forces of victory,
This is one of those condensed expressions which mean so much in Chinese, and so little in an English translation. What it seems to imply is complete mastery of the situation from the beginning.
and of shrewdly calculating difficulties, dangers and distances, constitutes the test of a great general.
As Chang Yü remarks, these are “the essentials of soldiering,” ground being only a helpful accessory.
22. He who knows these things, and in fighting puts his knowledge into practice, will win his battles. He who knows them not, nor practises them, will surely be defeated.
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.
Huang Shih-kung of the Ch’in dynasty [says]: “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 [
literally
, 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 Yü also quotes the saying: “Decrees of 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 presentment, 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.
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, ‘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’üan mentions the Viscount of Ch’u, who invaded the small state of Hsiao during the winter. The Duke of Shên 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 straight-way 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.
An adage states: “Injury comes out of kindness.” 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 Lü Mêng 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. Lü Mêng 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, as Ts’ao Kung says, “the issue in this case is uncertain.”
