You can be sure of succeeding in your attacks if you only attack places which are undefended.You can ensure the safety of your defense if you only hold positions that cannot be attacked.

Generally, management of many is the same as management of few. It is a matter of organization.

The general is the protector of the state. If this protection is all-embracing, the state will surely be strong; if defective, the state will certainly be weak. A sovereign who obtains the right person prospers. One who fails to do so will be ruined.

All warfare is based on deception. Hence, when we are able to attack, we must seem unable; when using our forces, we must appear inactive; when we are near, we must make the enemy believe we are far away; when far away, we must make him believe we are near.

Now war is based on deception. Move when it is advantageous and create changes in the situation by dispersal and concentration of forces. When campaigning, be swift as the wind; in leisurely march, majestic as the forest; in raiding and plundering, like fire; in standing, firm as the mountains. As unfathomable as the clouds, move like a thunderbolt. When you plunder the countryside, divide your forces. When you conquer territory, divide the profits. Weigh the situation, then move.

The crux of military operations lies in the pretense of accommodating one's self to the designs of the enemy.

When the enemy presents an opportunity, speedily take advantage of it. Anticipate him in seizing something he values and move in accordance with a date secretly fixed. The doctrine of war is to follow the enemy situation in order to decide on battle. Therefore at first be shy as a maiden. When the enemy gives you an opening be swift as a hare and he will be unable to withstand you.

If I am able to determine the enemy's dispositions while at the same time I conceal my own then I can concentrate and he must divide.
