The Art of War

18. In raiding and plundering be like fire,
    is immovability like a mountain.

19. Let your plans be dark and impenetrable as night,
    and when you move, fall like a thunderbolt.

20. When you plunder a countryside, let the spoil be
    divided amongst your men; when you capture new territory,
    cut it up into allotments for the benefit of the soldiery.

21. Ponder and deliberate before you make a move.

22. He will conquer who has learnt the artifice
    of deviation.  Such is the art of maneuvering.

23. The Book of Army Management says:  On the field
    of battle, the spoken word does not carry far enough: 
    hence the institution of gongs and drums.  Nor can ordinary
    objects be seen clearly enough:  hence the institution
    of banners and flags.

24. Gongs and drums, banners and flags, are means
    whereby the ears and eyes of the host may be focused
    on one particular point.

25. The host thus forming a single united body,
    is it impossible either for the brave to advance alone,
    or for the cowardly to retreat alone.  This is the art
    of handling large masses of men.

26. In night-fighting, then, make much use of signal-fires
    and drums, and in fighting by day, of flags and banners,
    as a means of influencing the ears and eyes of your army.

27. A whole army may be robbed of its spirit;
    a commander-in-chief may be robbed of his presence of mind.

28. Now a soldier's spirit is keenest in the morning;
    by noonday it has begun to flag; and in the evening,
    his mind is bent only on returning to camp.

29. A clever general, therefore, avoids an army when
    its spirit is keen, but attacks it when it is sluggish
    and inclined to return.  This is the art of studying moods.

30. Disciplined and calm, to await the appearance
    of disorder and hubbub amongst the enemy:--this is the art
    of retaining self-possession.

31. To be near the goal while the enemy is still
    far from it, to wait at ease while the enemy is
    toiling and struggling, to be well-fed while the enemy
    is famished:--this is the art of husbanding one's strength.

32. To refrain from intercepting an enemy whose
    banners are in perfect order, to refrain from attacking
    an army drawn up in calm and confident array:--this
    is the art of studying circumstances.

33. It is a military axiom not to advance uphill
    against the enemy, nor to oppose him when he comes downhill.

34. Do not pursue an enemy who simulates flight;
    do not attack soldiers whose temper is keen.

35. Do not swallow bait offered by the enemy. 
    Do not interfere with an army that is returning home.

36. When you surround an army, leave an outlet free. 
    Do not press a desperate foe too hard.

37. Such is the art of warfare.


VIII. VARIATION IN TACTICS


 1. Sun Tzu said:  In war, the general receives
    his commands from the sovereign, collects his army
    and concentrates his forces

 2. When in difficult country, do not encamp.  In country
    where high roads intersect, join hands with your allies. 
    Do not linger in dangerously isolated positions. 
    In hemmed-in situations, you must resort to stratagem. 
    In desperate position, you must fight.

 3. There are roads which must not be followed,
    armies which must be not attacked, towns which must
    not be besieged, positions which must not be contested,
    commands of the sovereign which must not be obeyed.

 4. The general who thoroughly understands the advantages
    that accompany variation of tactics knows how to handle
    his troops.

 5. The general who does not understand these, may be well
    acquainted with the configuration of the country, yet he
    will not be able to turn his knowledge to practical account.
