The Art of War by active 6th century B.C. Sunzi

25. The end and aim of spying in all its five varieties is knowledge of

the enemy; and this knowledge can only be derived, in the first instance, from the converted spy. [As explained in §§ 22-24. He not only brings information himself, but makes it possible to use the other kinds of spy to advantage.] Hence it is essential that the converted spy be treated with the utmost liberality.

Chapter I. LAYING PLANS Ch.52
2. It is a matter of life and death, a road either to safety or to Ch.53
3. The art of war, then, is governed by five constant factors, to be Ch.54
4. These are: (1) The Moral Law; (2) Heaven; (3) Earth; (4) The Ch.55
7. _Heaven_ signifies night and day, cold and heat, times and seasons. Ch.56
8. _Earth_ comprises distances, great and small; danger and security; Ch.57
9. _The Commander_ stands for the virtues of wisdom, sincerity, Ch.58
10. By _Method and discipline_ are to be understood the marshalling of Ch.59
11. These five heads should be familiar to every general: he who knows Ch.60
12. Therefore, in your deliberations, when seeking to determine the Ch.61
13. (1) Which of the two sovereigns is imbued with the Moral law? Ch.62
14. By means of these seven considerations I can forecast victory or Ch.63
15. The general that hearkens to my counsel and acts upon it, will Ch.64
16. While heeding the profit of my counsel, avail yourself also of any Ch.65
17. According as circumstances are favourable, one should modify one’s Ch.66
18. All warfare is based on deception. Ch.67
19. Hence, when able to attack, we must seem unable; when using our Ch.68
20. Hold out baits to entice the enemy. Feign disorder, and crush him. Ch.69
21. If he is secure at all points, be prepared for him. If he is in Ch.70
22. If your opponent is of choleric temper, seek to irritate him. Ch.71
23. If he is taking his ease, give him no rest. Ch.72
24. Attack him where he is unprepared, appear where you are not Ch.73
25. These military devices, leading to victory, must not be divulged Ch.74
26. Now the general who wins a battle makes many calculations in his Ch.75
Chapter II. WAGING WAR Ch.76
1. Sun Tzŭ said: In the operations of war, where there are in the field Ch.77
2. When you engage in actual fighting, if victory is long in coming, Ch.78
3. Again, if the campaign is protracted, the resources of the State Ch.79
4. Now, when your weapons are dulled, your ardour damped, your strength Ch.80
5. Thus, though we have heard of stupid haste in war, cleverness has Ch.81
6. There is no instance of a country having benefited from prolonged Ch.82
7. It is only one who is thoroughly acquainted with the evils of war Ch.83
8. The skilful soldier does not raise a second levy, neither are his Ch.84
9. Bring war material with you from home, but forage on the enemy. Thus Ch.85
10. Poverty of the State exchequer causes an army to be maintained by Ch.86
11. On the other hand, the proximity of an army causes prices to go up; Ch.87
12. When their substance is drained away, the peasantry will be Ch.88
15. Hence a wise general makes a point of foraging on the enemy. One Ch.89
16. Now in order to kill the enemy, our men must be roused to anger; Ch.90
17. Therefore in chariot fighting, when ten or more chariots have been Ch.91
18. This is called, using the conquered foe to augment one’s own Ch.92
19. In war, then, let your great object be victory, not lengthy Ch.93
20. Thus it may be known that the leader of armies is the arbiter of Ch.94
1. Sun Tzŭ said: In the practical art of war, the best thing of all is Ch.95
2. Hence to fight and conquer in all your battles is not supreme Ch.96
3. Thus the highest form of generalship is to baulk the enemy’s plans; Ch.97
4. The rule is, not to besiege walled cities if it can possibly be Ch.98
5. The general, unable to control his irritation, will launch his men Ch.99
6. Therefore the skilful leader subdues the enemy’s troops without any Ch.100
7. With his forces intact he will dispute the mastery of the Empire, Ch.101
8. It is the rule in war, if our forces are ten to the enemy’s one, to Ch.102
9. If equally matched, we can offer battle; Ch.103
10. Hence, though an obstinate fight may be made by a small force, in Ch.104
11. Now the general is the bulwark of the State: if the bulwark is Ch.105
12. There are three ways in which a ruler can bring misfortune upon his Ch.106
13. (1) By commanding the army to advance or to retreat, being ignorant Ch.107
14. (2) By attempting to govern an army in the same way as he Ch.108
15. (3) By employing the officers of his army without discrimination, Ch.109
16. But when the army is restless and distrustful, trouble is sure to Ch.110
17. Thus we may know that there are five essentials for victory: (1) He Ch.111
18. Hence the saying: If you know the enemy and know yourself, you need Ch.112
Chapter IV. TACTICAL DISPOSITIONS Ch.113
1. Sun Tzŭ said: The good fighters of old first put themselves beyond Ch.114
2. To secure ourselves against defeat lies in our own hands, but the Ch.115
3. Thus the good fighter is able to secure himself against defeat, Ch.116
4. Hence the saying: One may _know_ how to conquer without being able Ch.117
5. Security against defeat implies defensive tactics; ability to defeat Ch.118
6. Standing on the defensive indicates insufficient strength; Ch.119
7. The general who is skilled in defence hides in the most secret Ch.120
8. To see victory only when it is within the ken of the common herd is Ch.121
9. Neither is it the acme of excellence if you fight and conquer and Ch.122
10. To lift an autumn hair is no sign of great strength; Ch.123
11. What the ancients called a clever fighter is one who not only wins, Ch.124
12. Hence his victories bring him neither reputation for wisdom nor Ch.125
13. He wins his battles by making no mistakes. Ch.126
14. Hence the skilful fighter puts himself into a position which makes Ch.127
15. Thus it is that in war the victorious strategist only seeks battle Ch.128
16. The consummate leader cultivates the moral law, and strictly Ch.129
17. In respect of military method, we have, firstly, Measurement; Ch.130
18. Measurement owes its existence to Earth; Estimation of quantity to Ch.131
19. A victorious army opposed to a routed one, is as a pound’s weight Ch.132
20. The onrush of a conquering force is like the bursting of pent-up Ch.133
1. Sun Tzŭ said: The control of a large force is the same principle as Ch.134
2. Fighting with a large army under your command is nowise different Ch.135

8. There are not more than five primary colours (blue, yellow, red, Ch.141
10. In battle, there are not more than two methods of attack—the direct Ch.142
11. The direct and the indirect lead on to each other in turn. It is Ch.143
12. The onset of troops is like the rush of a torrent which will even Ch.144
13. The quality of decision is like the well-timed swoop of a falcon Ch.145
14. Therefore the good fighter will be terrible in his onset, and Ch.146
15. Energy may be likened to the bending of a crossbow; decision, to Ch.147
16. Amid the turmoil and tumult of battle, there may be seeming Ch.148
17. Simulated disorder postulates perfect discipline; simulated fear Ch.149
18. Hiding order beneath the cloak of disorder is simply a question of Ch.150
19. Thus one who is skilful at keeping the enemy on the move maintains Ch.151
20. By holding out baits, he keeps him on the march; then with a body Ch.152
21. The clever combatant looks to the effect of combined energy, and Ch.153
22. When he utilises combined energy, his fighting men become as it Ch.154
23. Thus the energy developed by good fighting men is as the momentum Ch.155
Chapter VI. WEAK POINTS AND STRONG Ch.156
1. Sun Tzŭ said: Whoever is first in the field and awaits the coming of Ch.157
2. Therefore the clever combatant imposes his will on the enemy, but Ch.158
3. By holding out advantages to him, he can cause the enemy to approach Ch.159
4. If the enemy is taking his ease, he can harass him; Ch.160

13. By discovering the enemy’s dispositions and remaining invisible Ch.169
14. We can form a single united body, while the enemy must split up Ch.170
15. And if we are able thus to attack an inferior force with a superior Ch.171
16. The spot where we intend to fight must not be made known; for then Ch.172
17. For should the enemy strengthen his van, he will weaken his rear; Ch.173
18. Numerical weakness comes from having to prepare against possible Ch.174
19. Knowing the place and the time of the coming battle, we may Ch.175
20. But if neither time nor place be known, then the left wing will be Ch.176
21. Though according to my estimate the soldiers of Yüeh exceed our own Ch.177
22. Though the enemy be stronger in numbers, we may prevent him from Ch.178
23. Rouse him, and learn the principle of his activity or inactivity. Ch.179
24. Carefully compare the opposing army with your own, so that you may Ch.180

27. All men can see the tactics whereby I conquer, but what none can Ch.183
28. Do not repeat the tactics which have gained you one victory, but Ch.184
29. Military tactics are like unto water; for water in its natural Ch.185
30. So in war, the way is to avoid what is strong and to strike at what Ch.186
31. Water shapes its course according to the nature of the ground over Ch.187
32. Therefore, just as water retains no constant shape, so in warfare Ch.188
33. He who can modify his tactics in relation to his opponent and Ch.189
34. The five elements (water, fire, wood, metal, earth) are not always Ch.190
1. Sun Tzŭ said: In war, the general receives his commands from the Ch.191
2. Having collected an army and concentrated his forces, he must blend Ch.192
3. After that, comes tactical manœuvering, than which there is nothing Ch.193
4. Thus, to take a long and circuitous route, after enticing the enemy Ch.194
5. Manœuvering with an army is advantageous; with an undisciplined Ch.195
6. If you set a fully equipped army in march in order to snatch an Ch.196
