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.

When one treats people with benevolence, justice, and righteoousness, and reposes confidence in them, the army will be united in mind and all will be happy to serve their leaders'.

He will win who, prepared himself, waits to take the enemy unprepared.

Bravery without forethought, causes a man to fight blindly and desperately like a mad bull.  Such an opponent, must not be encountered with brute force, but may be lured into an ambush and slain.

Great results, can be achieved with small forces.

If your opponent is of choleric temper,  seek to irritate him.  Pretend to be weak, that he may grow arrogant.
