Being unconquerable lies with yourself; being conquerable lies with your enemy.

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.

It is the business of a general to be quiet and thus ensure secrecy; upright and just, and thus maintain order.

Rely not on the likelihood of the enemy's not coming, but on our own readiness to receive him

Sweat more during peace: bleed less during war

If we know that the enemy is open to attack, but are unaware that our own men are not in a condition to attack, we have gone only halfway towards victory.

If their forces are substantial, prepare for them; if their forces are strong, avoid them.
