There are roads which must not be followed, armies which must not be attacked, towns which must not be besieged, positions which must not be contested, commands of the sovereign which must not be obeyed.
The spot where we intend to fight must not be made known; for then the enemy will have to prepare against a possible attack at several different points.
In battle, there are not more than two methods of attack–the direct and the indirect; yet these two in combination give rise to an endless series of maneuvers.
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.
