Sun Tzu's Art of War
1. Sun Tzu said:  We come now to the question of
    encamping the army, and observing signs of the enemy.
    Pass quickly over mountains, and keep in the neighborhood
    of valleys.

2. Camp in high places, facing the sun.  Do not climb
    heights in order to fight.  So much for mountain warfare.

3. After crossing a river, you should get far away
    from it.

4. When an invading force crosses a river in its
    onward march, do not advance to meet it in mid-stream.
    It will be best to let half the army get across,
    and then deliver your attack.

5. If you are anxious to fight, you should not go
    to meet the invader near a river which he has to cross.

6. Moor your craft higher up than the enemy, and facing
    the sun.  Do not move up-stream to meet the enemy.
    So much for river warfare.

7. In crossing salt-marshes, your sole concern
    should be to get over them quickly, without any delay.

8. If forced to fight in a salt-marsh, you should
    have water and grass near you, and get your back
    to a clump of trees.  So much for operations in salt-marches.

9. In dry, level country, take up an easily accessible
    position with rising ground to your right and on your rear,
    so that the danger may be in front, and safety lie behind.
    So much for campaigning in flat country.

10. These are the four useful branches of military
    knowledge which enabled the Yellow Emperor to vanquish
    four several sovereigns.

11. All armies prefer high ground to low and sunny
    places to dark.

12. If you are careful of your men, and camp on hard
    ground, the army will be free from disease of every kind,
    and this will spell victory.

13. When you come to a hill or a bank, occupy the
    sunny side, with the slope on your right rear.
    Thus you will at once act for the benefit of your soldiers
    and utilize the natural advantages of the ground.

14. When, in consequence of heavy rains up-country,
    a river which you wish to ford is swollen and flecked
    with foam, you must wait until it subsides.

15. Country in which there are precipitous cliffs
    with torrents running between, deep natural hollows,
    confined places, tangled thickets, quagmires and crevasses,
    should be left with all possible speed and not approached.

16. While we keep away from such places, we should
    get the enemy to approach them; while we face them,
    we should let the enemy have them on his rear.

17. If in the neighborhood of your camp there should
    be any hilly country, ponds surrounded by aquatic grass,
    hollow basins filled with reeds, or woods with thick
    undergrowth, they must be carefully routed out and searched;
    for these are places where men in ambush or insidious
    spies are likely to be lurking.

18. When the enemy is close at hand and remains quiet,
    he is relying on the natural strength of his position.

19. When he keeps aloof and tries to provoke a battle,
    he is anxious for the other side to advance.

20. If his place of encampment is easy of access,
    he is tendering a bait.

21. Movement amongst the trees of a forest shows that the
    enemy is advancing.  The appearance of a number of screens
    in the midst of thick grass means that the enemy wants to make us suspicious.

22. The rising of birds in their flight is the sign
    of an ambuscade.  Startled beasts indicate that a sudden
    attack is coming.

23. When there is dust rising in a high column,
    it is the sign of chariots advancing; when the dust is low,
    but spread over a wide area, it betokens the approach
    of infantry.  When it branches out in different directions,
    it shows that parties have been sent to collect firewood.
    A few clouds of dust moving to and fro signify that the army
    is encamping.

24. Humble words and increased preparations are signs
    that the enemy is about to advance.  Violent language
    and driving forward as if to the attack are signs that he
    will retreat.

25. When the light chariots come out first and take
    up a position on the wings, it is a sign that the enemy
    is forming for battle.

26. Peace proposals unaccompanied by a sworn covenant
    indicate a plot.

27. When there is much running about and the soldiers
    fall into rank, it means that the critical moment has come.

28. When some are seen advancing and some retreating,
    it is a lure.

29. When the soldiers stand leaning on their spears,
    they are faint from want of food.

30. If those who are sent to draw water begin
    by drinking themselves, the army is suffering from thirst.

31. If the enemy sees an advantage to be gained and
    makes no effort to secure it, the soldiers are exhausted.

32. If birds gather on any spot, it is unoccupied.
    Clamor by night betokens nervousness.

33. If there is disturbance in the camp, the general's
    authority is weak.  If the banners and flags are shifted
    about, sedition is afoot.  If the officers are angry,
    it means that the men are weary.

34. When an army feeds its horses with grain and kills
    its cattle for food, and when the men do not hang their
    cooking-pots over the camp-fires, showing that they
    will not return to their tents, you may know that they
    are determined to fight to the death.

35. The sight of men whispering together in small
    knots or speaking in subdued tones points to disaffection
    amongst the rank and file.

36. Too frequent rewards signify that the enemy is
    at the end of his resources; too many punishments betray
    a condition of dire distress.

37. To begin by bluster, but afterwards to take fright
    at the enemy's numbers, shows a supreme lack of intelligence.

38. When envoys are sent with compliments in their mouths,
    it is a sign that the enemy wishes for a truce.

39. If the enemy's troops march up angrily and remain
    facing ours for a long time without either joining
    battle or taking themselves off again, the situation
    is one that demands great vigilance and circumspection.

40. If our troops are no more in number than the enemy,
    that is amply sufficient; it only means that no direct attack
    can be made.  What we can do is simply to concentrate all
    our available strength, keep a close watch on the enemy,
    and obtain reinforcements.

41. He who exercises no forethought but makes light
    of his opponents is sure to be captured by them.

42. If soldiers are punished before they have grown
    attached to you, they will not prove submissive; and,
    unless submissive, then will be practically useless.
    If, when the soldiers have become attached to you,
    punishments are not enforced, they will still be unless.

43. Therefore soldiers must be treated in the first
    instance with humanity, but kept under control by means
    of iron discipline.  This is a certain road to victory.

44. If in training soldiers commands are habitually
    enforced, the army will be well-disciplined; if not,
    its discipline will be bad.

45. If a general shows confidence in his men but always
    insists on his orders being obeyed, the gain will be mutual.
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.
