The Mask of Command: Alexander the Great, Wellington, Ulysses S. Grant, Hitler, and the Nature of Lea dership by John Keegan
A wide-ranging, forceful, and fascinating analysis of generals - who they are, what they do, and how they affect the world we live in. Its central argument is that, like warfare itself, generalship is a cultural activity, providing a key to understanding a particular place or era, as much as it is an exercise in power or military skill. Other books by the same author include: The Face Of Battle, Who's Who In Military History and The Nature of War.
