To capture an enemies army is better than to destroy it.
When your opponent gives you an opening, be swift as a hare.
Without harmony in the State, no military expedition can be undertaken; without harmony in the army, no battle array can be formed.
The line between disorder and order lies in logistics.
To persuade your enemy to (retreat) before the fight is to defeat them even before the battle begins. An enemy made ally is no longer an enemy.
Know thy enemy and know thy self and you will win a hundred battles.
