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

A warrior who is prepared to fight must also be prepared to die.

To capture an enemies army is better than to destroy it.

It is the rule in war, if our forces are ten to the enemy's one, to surround him; if five to one, to attack him; if twice as numerous, to divide our army into two.

Appear at points which the enemy must hasten to defend; march swiftly to places where you are not expected.

It is said that if you know your enemies and know yourself, you will not be imperiled in a hundred battles; if you do not know your enemies but do know yourself, you will win one and lose one; if you do not know your enemies nor yourself, you will be imperiled in every single battle.

When you are ignorant of the enemy but know yourself, your chances of winning or losing are equal.
