A wise general makes a point of foraging of the enemy.

One who has few must prepare against the enemy; one who has many makes the enemy prepare against him.

In a position of this sort, even though the enemy should offer us an attractive bait, it will be advisable not to stir forth, but rather to retreat, thus enticing the enemy in his turn; then, when part of his army has come out, we may deliver our attack with advantage.

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.

It is a doctrine of war not to assume the enemy will not come, but rather to rely on one's readiness to meet him; not to presume that he will not attack, but rather to make one's self invincible.

If fighting is sure to result in victory, then you must fight.

Convince your enemy that he will gain very little by attacking you; this will diminish his enthusiasm
