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; and his forces being thus distributed in many directions, the numbers we shall have to face at any given point will be proportionately few.
Sun TzuIf you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.
Sun TzuThe good fighter is able to secure himself against defeat, but cannot make certain of defeating the enemy.
Sun TzuHence the experienced soldier, once in motion, is never bewildered; once he has broken camp, he is never at a loss.
