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 10: Terrain
1. Sun Tzu said: We may distinguish six kinds of terrain, to wit: (1) Accessible
ground; (2) entangling ground; (3) temporizing ground; (4) narrow passes; (5) precipitous
heights; (6) positions at a great distance from the enemy.
2. Ground which can be freely traversed by both sides is called accessible.
3. With regard to ground of this nature, be before the enemy in occupying the raised
and sunny spots, and carefully guard your line of supplies. Then you will be able to fight
with advantage.
4. Ground which can be abandoned but is hard to re-occupy is called entangling.
5. From a position of this sort, if the enemy is unprepared, you may sally forth and
defeat him. But if the enemy is prepared for your coming, and you fail to defeat him,
then, return being impossible, disaster will ensue.
6. When the position is such that neither side will gain by making the first move, it
is called temporizing ground.
7. In a position of this sort, even though the enemy should offer us an attractive
bait, it will be advisable not to stir forth, but rather to retreat, thus enticing the
enemy in his turn; then, when part of his army has come out, we may deliver our attack
with advantage.
8. With regard to narrow passes, if you can occupy them first, let them be strongly
garrisoned and await the advent of the enemy.
9. Should the army forestall you in occupying a pass, do not go after him if the pass
is fully garrisoned, but only if it is weakly garrisoned.
10. With regard to precipitous heights, if you are beforehand with your adversary, you
should occupy the raised and sunny spots, and there wait for him to come up.
11. If the enemy has occupied them before you, do not follow him, but retreat and try
to entice him away.
12. If you are situated at a great distance from the enemy, and the strength of the two
armies is equal, it is not easy to provoke a battle, and fighting will be to your
disadvantage.
13. These six are the principles connected with Earth. The general who has attained a
responsible post must be careful to study them.
14. Now an army is exposed to six several calamities, not arising from natural causes,
but from faults for which the general is responsible. These are: (1) Flight; (2)
insubordination; (3) collapse; (4) ruin; (5) disorganization; (6) rout.
15. Other conditions being equal, if one force is hurled against another ten times its
size, the result will be the flight of the former.
16. When the common soldiers are too strong and their officers too weak, the result is
insubordination. When the officers are too strong and the common soldiers too weak, the
result is collapse.
17. When the higher officers are angry and insubordinate, and on meeting the enemy give
battle on their own account from a feeling of resentment, before the commander-in-chief
can tell whether or no he is in a position to fight, the result is ruin.
18. When the general is weak and without authority; when his orders are not clear and
distinct; when there are no fixes duties assigned to officers and men, and the ranks are
formed in a slovenly haphazard manner, the result is utter disorganization.
19. When a general, unable to estimate the enemy's strength, allows an inferior force
to engage a larger one, or hurls a weak detachment against a powerful one, and neglects to
place picked soldiers in the front rank, the result must be rout.
20. These are six ways of courting defeat, which must be carefully noted by the general
who has attained a responsible post.
21. The natural formation of the country is the soldier's best ally; but a power of
estimating the adversary, of controlling the forces of victory, and of shrewdly
calculating difficulties, dangers and distances, constitutes the test of a great
general.
22. He who knows these things, and in fighting puts his knowledge into practice, will
win his battles. He who knows them not, nor practices 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.
24. The general who advances without coveting fame and retreats without fearing
disgrace, whose only thought is to protect his country and do good service for his
sovereign, is the jewel of the kingdom.
25. Regard your soldiers as your children, and they will follow you into the deepest
valleys; look upon them as your own beloved sons, and they will stand by you even unto
death.
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.
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.
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.
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.
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.
