Here's a book that, I think, is more talked about than read, but the current conflict against terrorism makes Sun Tzu's The Art of War even more interesting reading. One of the earliest known military treatises, it emphasizes intelligence, terrain, mobility, morale and supply and hardly mentions tactics. Here are two quotes:
Hence to fight and conquer in all your battles is not supreme excellence; supreme excellence consists in breaking the enemy's resistance without fighting.
All warfare is based on deception. Hence, when able to attack, we must seem unable; when using our forces, we must seem inactive; when we are near, we must make the enemy believe we are far away; when far away, we must make him believe we are near.
Just to show that Sun Tzu's analysis remains relevant, consider WWII's Operation Fortitude South. Prior to the Normandy invasion, German intelligence detected radio traffic concerning the Fifth Army Group massing in southern England, with the redoubtable Gen. George Patton in command. Aerial reconnaisance showed massive buildup of tanks and landing craft. All indications pointed to Allied plans to land in Calais. But the radio messages were faked, and the military equipment phony (I've seen pictures of four soldiers carrying an inflatable dummy "tank"). Still, the deception was so thorough that when the actual Normandy invasion occurred, Hitler was convinced it was a feint, and rather than reinforce there, sent troops to Calais to counter the expected "real" invasion.
