Attack is the secret of defense; defense is the planning of an attack.
Those whose upper and lower ranks have the same desire are victorious.
First learn to become invincible, then wait for your enemy's moment of vulnerability.
Rely not on the likelihood of the enemy's not coming, but on our own readiness to receive him
If words of command are not clear and distinct, if orders are not thoroughly understood, the general is to blame. But if his orders are clear, and the soldiers nevertheless disobey, then it is the fault of their officers.
Do not press an enemy at bay.
