The skillful leader subdues the enemy's troops without any fighting.
O divine art of subtlety and secrecy!
If you know both yourself and your enemy, you can win a hundred battles without a single loss.
He who is prudent and lies in wait for an enemy who is not, will be victorious.
Whoever is first in the field and awaits the coming of the enemy, will be fresh for the fight; whoever is second in the field and has to hasten to battle will arrive exhausted.
To plan secretly, to move surreptitiously, to foil the enemy's intentions and balk his schemes, so that at last the day may be won without shedding a drop of blood.
