The
army on the march
"There
is no instance of a country having benefited from prolonged warfare"

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.
