13,14. With this loss of substance and exhaustion of strength, the homes of the people will be stripped bare, and three-tenths of their income will be dissipated; while government expenses for broken chariots, worn-out horses, breast-plates and helmets, bows and arrows, 6
Sun Tzu on the Art of War
spears and shields, protective mantles, draught-oxen and heavy wagons, will amount to four-tenths of its total revenue.
15. Hence a wise general makes a point of foraging on the enemy. One cartload of the enemy’s provisions is equivalent to twenty of one’s own, and likewise a single picul of his provender is equivalent to twenty from one’s own store.
16. Now in order to kill the enemy, our men must be roused to anger; that there may be advantage from defeating the enemy, they must have their rewards.
17. Therefore in chariot fighting, when ten or more chariots have been taken, those should be rewarded who took the first. Our own flags should be substituted for those of the enemy, and the chariots mingled and used in conjunction with ours. The captured soldiers should be kindly treated and kept.
18. This is called, using the conquered foe to augment one’s own strength.
19. In war, then, let your great object be victory, not lengthy campaigns.
20. Thus it may be known that the leader of armies is the arbiter of the people’s fate, the man on whom it depends whether the nation shall be in peace or in peril.

Attack by Stratagem
1 . Sun Tzu said: In the practical art of war, the best thing of all is to take the enemy’s country whole and intact; to shatter and destroy it is not so good. So, too, it is better to recapture an army entire than to destroy it, to capture a regiment, a detachment or a company entire than to destroy them.
2. Hence to fight and conquer in all your battles is not supreme excellence; supreme excellence consists in breaking the enemy’s resistance without fighting.
3. Thus the highest form of generalship is to balk the enemy’s plans; the next best is to prevent the junction of the enemy’s forces; the next in order is to attack the enemy’s army in the field; and the worst policy of all is to besiege walled cities.
4. The rule is, not to besiege walled cities if it can possibly be avoided. The preparation of mantlets, movable shelters, and various implements of war, will take up three whole months; and the piling up of mounds over against the walls will take three months more.
5. The general, unable to control his irritation, will launch his men to the assault like swarming ants, with the result that one-third of his men are slain while the 8

town still remains untaken. Such are the disastrous effects of a siege.
6. Therefore the skillful leader subdues the enemy’s troops without any fighting; he captures their cities without laying siege to them; he overthrows their kingdom without lengthy operations in the field.
7. With his forces intact he will dispute the mastery of the Empire, and thus, without losing a man, his triumph will be complete. This is the method of attacking by stratagem.
8. It is the rule in war, if our forces are ten to the enemy’s one, to surround him; if five to one, to attack him; if twice as numerous, to divide our army into two.
9. If equally matched, we can offer battle; if slightly inferior in numbers, we can avoid the enemy; if quite unequal in every way, we can flee from him.
10. Hence, though an obstinate fight may be made by a small force, in the end it must be captured by the larger force.
11. Now the general is the bulwark of the State; if the bulwark is complete at all points; the State will be strong; if the bulwark is defective, the State will be weak.

12. There are three ways in which a ruler can bring misfortune upon his army:—
13. (1) By commanding the army to advance or to retreat, being ignorant of the fact that it cannot obey.
This is called hobbling the army.
14. (2) By attempting to govern an army in the same way as he administers a kingdom, being ignorant of the conditions which obtain in an army. This causes restlessness in the soldier’s minds.
15. (3) By employing the officers of his army without discrimination, through ignorance of the military principle of adaptation to circumstances. This shakes the confidence of the soldiers.
16. But when the army is restless and distrustful, trouble is sure to come from the other feudal princes. This is simply bringing anarchy into the army, and flinging victory away.
17. Thus we may know that there are five essentials for victory:
(1) He will win who knows when to fight and when not to fight.
