Thus the skilful general conducts his army just as though he were leading a single man, willy-nilly, by the hand.
Attack where he is unprepared; sally forth when he does not expect you.
For to win one hundred victories in one hundred battles is not the acme of skill. To subdue the enemy without fighting is the acme of skill.
Keep your friends close and your enemies even closer.
Weigh the situation, then move.
It is only one who is thoroughly acquainted with the evils of war that can thoroughly understand the profitable way of carrying it on.
