The MORAL LAW causes the people to be in complete accord with their ruler, so that they will follow him regardless of their lives, undismayed by any danger.
Move not unless you see an advantage; use not your troops unless there is something to be gained; fight not unless the position is critical.
Treat your men as you would your own beloved sons. And they will follow you into the deepest valley.
Put them in a spot where they have no place to go, and they will die before fleeing.
In difficult ground, press on; In encircled ground, devise stratagems; In death ground, fight.
The Art of War is self-explanatory.
