A warrior who is prepared to fight must also be prepared to die.

If there is disturbance in the camp, the general's authority is weak. If the banners and flags are shifted about, sedition is afoot. If the officers are angry, it means that the men are weary.

Therefore, just as water retains no constant shape, so in warfare there are no constant conditions.

Whoever is first in the field and awaits the coming of the enemy, will be fresh for the fight; whoever is second in the field and has to hasten to battle will arrive exhausted.

If you know both yourself and your enemy, you can win a hundred battles without a single loss.

It is more important to outhink your enemy, than to outfight him

The spot where we intend to fight must not be made known; for then the enemy will have to prepare against a possible attack at several different points; and his forces being thus distributed in many directions, the numbers we shall have to face at any given point will be proportionately few.
