“Ground on which we can only be saved from destruction by fighting without delay, is desperate ground.”

“Sun Tzu said: The art of war recognises nine varieties of ground: (1) Dispersive ground; (2) facile ground; (3) contentious ground; (4) open ground; (5) ground of intersecting highways; (6) serious ground; (7) difficult ground; (8) hemmed-in ground; (9) desperate ground.”

“On open ground, do not try to block the enemy's way. On the ground of intersecting highways, join hands with your allies.”

“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.”

“Know your enemy and know yourself and you can fight a hundred battles without disaster”

“The supreme art of war is to subdue the enemy without fighting.”

“To fight and conquer in all your battles is not supreme excellence; supreme excellence consists in breaking the enemy's resistance without fighting.”
