To fight and conquer in all our battles is not supreme excellence; supreme excellence consists in breaking the enemy's resistance without fighting.
Sun TzuUnless you know the mountains and the forests, the defiles and impasses, the lay of the marshes and swamps, you cannot maneuver with an armed force. Unless you use local guides, you cannot get the advantages of the land.
Sun TzuIn all fighting, the direct method may be used for joining battle, but indirect methods will be needed in order to secure victory.
Sun Tzu
