So the principles of warfare are: Do not depend on the enemy not coming, but depend on our readiness against him. Do not depend on the enemy not attacking, but depend on our position that cannot be attacked.

If, however, you are indulgent, but unable to make your authority felt; kind-hearted, but unable to enforce your commands; and incapable, moreover, of quelling disorder: then your soldiers must be likened to spoilt children; they are useless for any practical purpose.

To conquer the enemy without resorting to war is the most desirable. The highest form of generalship is to conquer the enemy by strategy.

When envoys are sent with compliments in their mouths, it is a sign that the enemy wishes for a truce.

One whose troops repeatedly congregate in small groups here and there, whispering together, has lost the masses. One who frequently grants rewards is in deep distress. One who frequently imposes punishments is in great difficulty. One who is at first excessively brutal and then fears the masses is the pinnacle of stupidity.

Secret operations are essential in war; upon them the army relies to make its every move.

Know the enemy and know yourself; in a hundred battles you will never peril.
