Re: Re: Sun Tzu's Art of War
From IX.  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.
 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.
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.
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.
Unfortunately, Sun Tzu doesn't always explain the rationale behind his advice.
