SUN TZU ON THE ART OF WAR
THE OLDEST MILITARY TREATISE IN THE WORLD Translated from the Chinese By LIONEL GILES,
M.A. (1910) Chapter 6: Weak an dStrong Points
1. Sun Tzu said: Whoever is first in the field and awaits the coming of the enemy, will
be fresh for the fight; whoever is second in the field and has to hasten to battle will
arrive exhausted.
2. Therefore the clever combatant imposes his will on the enemy, but does not allow the
enemy's will to be imposed on him.
3. By holding out advantages to him, he can cause the enemy to approach of his own
accord; or, by inflicting damage, he can make it impossible for the enemy to draw
near.
4. If the enemy is taking his ease, he can harass him; if well supplied with food, he
can starve him out; if quietly encamped, he can force him to move.
5. Appear at points which the enemy must hasten to defend; march swiftly to places
where you are not expected.
6. An army may march great distances without distress, if it marches through country
where the enemy is not.
7. You can be sure of succeeding in your attacks if you only attack places which are
undefended.You can ensure the safety of your defense if you only hold positions that
cannot be attacked.
8. Hence that general is skillful in attack whose opponent does not know what to
defend; and he is skillful in defense whose opponent does not know what to attack.
9. O divine art of subtlety and secrecy! Through you we learn to be invisible, through
you inaudible; and hence we can hold the enemy's fate in our hands.
10. You may advance and be absolutely irresistible, if you make for the enemy's weak
points; you may retire and be safe from pursuit if your movements are more rapid than
those of the enemy.
11. If we wish to fight, the enemy can be forced to an engagement even though he be
sheltered behind a high rampart and a deep ditch. All we need do is attack some other
place that he will be obliged to relieve.
12. If we do not wish to fight, we can prevent the enemy from engaging us even though
the lines of our encampment be merely traced out on the ground. All we need do is to throw
something odd and unaccountable in his way.
13. By discovering the enemy's dispositions and remaining invisible ourselves, we can
keep our forces concentrated, while the enemy's must be divided.
14. We can form a single united body, while the enemy must split up into fractions.
Hence there will be a whole pitted against separate parts of a whole, which means that we
shall be many to the enemy's few.
15. And if we are able thus to attack an inferior force with a superior one, our
opponents will be in dire straits.
16. The spot where we intend to fight must not be made known; for then the enemy will
have to prepare against a possible attack at several different points; and his forces
being thus distributed in many directions, the numbers we shall have to face at any given
point will be proportionately few.
17. For should the enemy strengthen his van, he will weaken his rear; should he
strengthen his rear, he will weaken his van; should he strengthen his left, he will weaken
his right; should he strengthen his right, he will weaken his left. If he sends
reinforcements everywhere, he will everywhere be weak.
18. Numerical weakness comes from having to prepare against possible attacks; numerical
strength, from compelling our adversary to make these preparations against us.
19. Knowing the place and the time of the coming battle, we may concentrate from the
greatest distances in order to fight.
20. But if neither time nor place be known, then the left wing will be impotent to
succor the right, the right equally impotent to succor the left, the van unable to relieve
the rear, or the rear to support the van. How much more so if the furthest portions of the
army are anything under a hundred LI apart, and even the nearest are separated by several
LI!
21. Though according to my estimate the soldiers of Yueh exceed our own in number, that
shall advantage them nothing in the matter of victory. I say then that victory can be
achieved.
22. Though the enemy be stronger in numbers, we may prevent him from fighting. Scheme
so as to discover his plans and the likelihood of their success.
23. Rouse him, and learn the principle of his activity or inactivity. Force him to
reveal himself, so as to find out his vulnerable spots.
24. Carefully compare the opposing army with your own, so that you may know where
strength is superabundant and where it is deficient.
25. In making tactical dispositions, the highest pitch you can attain is to conceal
them; conceal your dispositions, and you will be safe from the prying of the subtlest
spies, from the machinations of the wisest brains.
26. How victory may be produced for them out of the enemy's own tactics--that is what
the multitude cannot comprehend.
27. All men can see the tactics whereby I conquer, but what none can see is the
strategy out of which victory is evolved.
28. Do not repeat the tactics which have gained you one victory, but let your methods
be regulated by the infinite variety of circumstances.
29. Military tactics are like unto water; for water in its natural course runs away
from high places and hastens downwards.
30. So in war, the way is to avoid what is strong and to strike at what is weak.
31. Water shapes its course according to the nature of the ground over which it flows;
the soldier works out his victory in relation to the foe whom he is facing.
32. Therefore, just as water retains no constant shape, so in warfare there are no
constant conditions.
33. He who can modify his tactics in relation to his opponent and thereby succeed in
winning, may be called a heaven-born captain.
34. The five elements (water, fire, wood, metal, earth) are not always
equally predominant; the four seasons make way for each other in turn. There are short
days and long; the moon has its periods of waning and waxing.
