Sun Tzu's Art of War
1. Sun Tzu said:  The control of a large force
    is the same principle as the control of a few men:
    it is merely a question of dividing up their numbers.

2. Fighting with a large army under your command
    is nowise different from fighting with a small one:
    it is merely a question of instituting signs and signals.

3. To ensure that your whole host may withstand
    the brunt of the enemy's attack and remain unshaken--
    this is effected by maneuvers direct and indirect.

4. That the impact of your army may be like a grindstone
    dashed against an egg--this is effected by the science
    of weak points and strong.

5. In all fighting, the direct method may be used
    for joining battle, but indirect methods will be needed
    in order to secure victory.

6. Indirect tactics, efficiently applied, are inexhaustible
    as Heaven and Earth, unending as the flow of rivers and streams;
    like the sun and moon, they end but to begin anew;
    like the four seasons, they pass away to return once more.

7. There are not more than five musical notes,
    yet the combinations of these five give rise to more
    melodies than can ever be heard.

8. There are not more than five primary colors
    (blue, yellow, red, white, and black), yet in combination
    they produce more hues than can ever been seen.

9. There are not more than five cardinal tastes
    (sour, acrid, salt, sweet, bitter), yet combinations
    of them yield more flavors than can ever be tasted.

10. In battle, there are not more than two methods
    of attack--the direct and the indirect; yet these two
    in combination give rise to an endless series of maneuvers.

11. The direct and the indirect lead on to each other in turn.
    It is like moving in a circle--you never come to an end.
    Who can exhaust the possibilities of their combination?

12. The onset of troops is like the rush of a torrent
    which will even roll stones along in its course.

13. The quality of decision is like the well-timed
    swoop of a falcon which enables it to strike and destroy
    its victim.

14. Therefore the good fighter will be terrible
    in his onset, and prompt in his decision.

15. Energy may be likened to the bending of a crossbow;
    decision, to the releasing of a trigger.

16. Amid the turmoil and tumult of battle, there may
    be seeming disorder and yet no real disorder at all;
    amid confusion and chaos, your array may be without head
    or tail, yet it will be proof against defeat.

17. Simulated disorder postulates perfect discipline,
    simulated fear postulates courage; simulated weakness
    postulates strength.

18. Hiding order beneath the cloak of disorder is
    simply a question of subdivision; concealing courage under
    a show of timidity presupposes a fund of latent energy;
    masking strength with weakness is to be effected
    by tactical dispositions.

19. Thus one who is skillful at keeping the enemy
    on the move maintains deceitful appearances, according to
    which the enemy will act.  He sacrifices something,
    that the enemy may snatch at it.

20. By holding out baits, he keeps him on the march;
    then with a body of picked men he lies in wait for him.

21. The clever combatant looks to the effect of combined
    energy, and does not require too much from individuals.
    Hence his ability to pick out the right men and utilize
    combined energy.

22. When he utilizes combined energy, his fighting
    men become as it were like unto rolling logs or stones.
    For it is the nature of a log or stone to remain
    motionless on level ground, and to move when on a slope;
    if four-cornered, to come to a standstill, but if
    round-shaped, to go rolling down.

23. Thus the energy developed by good fighting men
    is as the momentum of a round stone rolled down a mountain
    thousands of feet in height.  So much on the subject
    of energy.
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.
