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

When your opponent gives you an opening, be swift as a hare.

If this is long delayed, weapons are blunted and morale depressed.

To perceive victory when it is known to all is not really skilful. Everyone calls victory in battle good, but it is not really good.

If the enemy leaves a door open, you must rush in.

Unless you know the mountains and the forests, the defiles and impasses, the lay of the marshes and swamps, you cannot maneuver with an armed force. Unless you use local guides, you cannot get the advantages of the land.

If we do not wish to fight, we can prevent the enemy from engaging us even though the lines of our encampment be merely traced out on the ground. All we need to do is to throw something odd and unaccountable in his way.
