Should one ask: 'how do I cope with a well-ordered enemy host about to attack me?' I reply: seize something he cherishes and he will conform to your desires.

Pretend to be weak, so your enemy may grow arrogant.

So a military force has no constant formation, water has no constant shape: the ability to gain victory by changing and adapting according to the opponent is called genius.

Prohibit the taking of omens, and do away with superstitious doubts. Then, until death itself comes, no calamity need be feared.

Ultimate excellence lies not in winning every battle, but in defeating the enemy without ever fighting.

With regard to narrow passes, if you can occupy them first, let them be strongly garrisoned and await the advent of the enemy.

In war, practice dissimulation and you will succeed.
