With regard to marshes:—
Cross salty marshes quickly; do not linger near them.
If by chance compelled to fight in the neighbourhood of a marsh, seek a place where there is water and grass, and trees in plenty in the rear.
In open country place the army in a convenient place with rising ground in the right rear; so that while in front lies death, behind there is safety.
Such is war in flat country.
Huangti, by observing these things, gained the victory over four Princes.
As a rule, the soldiers prefer high ground to low. They prefer sunny places to those the sun does not reach.
If the health of the troops be considered, and they are encamped on high and sunny ground, diseases will be avoided, and victory made certain.
If there be rising ground, encamp on its sunny side and in front of it; for thereby the soldiers are benefited, and the ground used to our advantage.
