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 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.

6. So, the student of war who is unversed in the art of war of varying his plans, even though he be acquainted with the Five Advantages, will fail to make the best use of his men.
7. Hence in the wise leader’s plans, considerations of advantage and of disadvantage will be blended together.
8. If our expectation of advantage be tempered in this way, we may succeed in accomplishing the essential part of our schemes.
9. If, on the other hand, in the midst of difficulties we are always ready to seize an advantage, we may extri-cate ourselves from misfortune.
10. Reduce the hostile chiefs by inflicting damage on them; and make trouble for them, and keep them constantly engaged; hold out specious allurements, and make them rush to any given point.
11. The art of war teaches us to rely not on the likelihood of the enemy’s not coming, but on our own readiness to receive him; not on the chance of his not attacking, but rather on the fact that we have made our position unassailable.
12. There are five dangerous faults which may affect a general:
(1) Recklessness, which leads to destruction; 31
Sun Tzu on the Art of War
(2) cowardice, which leads to capture; (3) a hasty temper, which can be provoked by insults;
(4) a delicacy of honor which is sensitive to shame; (5) over-solicitude for his men, which exposes him to worry and trouble.
13. These are the five besetting sins of a general, ruinous to the conduct of war.
14. When an army is overthrown and its leader slain, the cause will surely be found among these five dangerous faults. Let them be a subject of meditation.

The Army on the March
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.

Sun Tzu on the Art of War
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 van-quish 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, con-34
