Most times these books are only free for a day or two, so you have to grab them while you can. Worry about whether you really want to read it later if it seems interesting. And be careful, they can change from free to not free at any time.
I have decided to list books for no more than one day to avoid cluttering up the posts, unless there is some reason I think the book deserves extra attention.I have also decided to consolidate to a single post, instead of sometimes splitting them up by subject matter.

Leadership: The Warrior's Art
Foreword by Gen. Barry R. McCaffrey, USA (Ret.)
Contributors include Gen. Gordon Sullivan, former U.S. Army Chief of Staff; Conrad Crane; Fred Kagan
This bold, wide-ranging collection brings together some of the most noted military minds, past and present, to examine the crucial role of leadership in combat. Written while Christopher Kolenda was a faculty member in the history department at West Point, it covers both classic and modern concepts of leadership and uses case studies from Alexander the Great through World War II to illustrate principles of leadership in concrete historical contexts.
