To Subdue an enemy without fighting is the greatest of skills

Against those skilled in attack, an enemy does not know where to defend; against the experts in defense, the enemy does not know where to attack.

For them to perceive the advantage of defeating the enemy, they must also have their rewards.

The nature of war is constant change.

On the field of battle, the spoken word does not carry far enough; hence the institution of gongs and drums... banners and flags. Gongs and drums, banners and flags, are means whereby the ears and eyes of the host may be focused on one particular point.

Attack is the secret of defense; defense is the planning of an attack.

To a surrounded enemy, you must leave a way of escape.
