Amid the turmoil and tumult of battle, there may be seeming disorder and yet no real disorder at all.

What is essential in war is victory, not prolonged operations.

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

The ultimate in disposing one's troops is to be without ascertainable shape. Then the most penetrating spies cannot pry in nor can the wise lay plans against you.

It is essential to seek out enemy agents who have come to conduct espionage against you and to bribe them to serve you. Give them instructions and care for them. Thus doubled agents are recruited and used.

All warfare is based on deception. Therefore, when capable, feign incapacity; when active, inactivity. When near, make it appear that you are far away; when far away, that you are to lure him; feign disorder and strike him. When he concentrates, prepare against him; where he is strong, avoid him. Anger his general and confuse him. Pretend inferiority and encourage his arrogance.

Subjugating the enemy's army without fighting is the true pinnacle of excellence.
