“Throw your soldiers into positions whence there is no escape, and they will prefer death to flight. If they will face death, there is nothing they may not achieve. Officers and men alike will put forth their uttermost strength. Soldiers in desperate straits lose the sense of fear. If there is no place of refuge, they will stand firm. If they are in the heart of a hostile country, they will show a stubborn front. If there is no help for it, they will fight hard. Thus, without waiting to be marshaled, the soldiers will be constantly on the alert, and without waiting to be asked, they will do your will; without restrictions, they will be faithful; without giving orders, they can be trusted.
Prohibit the taking of omens, and do away with superstitious doubts.
Then, until death itself comes, no calamity need be feared.”
― Sun Tzu, The Art Of War
