At the crossing of highways, cultivate intercourse.
When deeply involved, levy and store up the enemy’s property.
Quickly depart from difficult ground.
On enclosed ground, use stratagem.
On death ground, fight.
The skilful fighters of old were at pains to disconnect the enemy’s front and rear; they cut asunder small and large forces of the enemy; prevented mutual help between his officers and men; spread mistrust between high and low. They scattered the enemy, and prevented him from concentrating; if his soldiers were assembled, they were without unity.
If there be a chance of victory, move; if there be no chance of success, stand fast.
If I were asked how a powerful and united force of the enemy should be met, I would say: lay hands on what the enemy cherishes and he will conform to our desires.
In war, above all, speed sustains the spirit of the troops. Strike before the enemy is ready; and attack his unpreparedness from an unexpected quarter.
