There are routes not to be followed, armies not to be attacked, citadels not to be besieged, territory not to be fought over.

When I have won a victory I do not repeat my tactics but respond to circumstances in an infinite variety of ways.

So in war, the way is to avoid what is strong, and strike at what is weak.

To see victory only when it is within the ken of the common herd is not the acme of excellence.

Know thy self, know thy enemy.

To maintain an army at a distance causes the people to be impoverished.

The line between disorder and order lies in logistics.
