Know thy self, know thy enemy.

Place your army in deadly peril, and it will survive; plunge it into desperate straits, and it will come off in safety.

Perfection in war lies in so sapping your opponents will that he surrenders without fighting.

If you fight with all your might, there is a chance of life; where as death is certain if you cling to your corner

It is the rule in war, if ten times the enemy's strength, surround them; if five times, attack them; if double, be able to divide them; if equal, engage them; if fewer, defend against them; if weaker, be able to avoid them.

Rapidity is the essence of war.

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