This is a very good book about the events leading up to, and the actual battle of Antietam. A must read for any Civil War buff.
The battle of Antietam wielded enormous influence over the course of the cival war. Although not a decisive tactical victory, it boosted the Union cause in profoundly important ways. James A. Mcpherson's engaging and perceptive narrative places Antietam within the broader context of the war, assessing major commanders, evaluating strategic decisions and movements, and explaining the battle's background as well as its seismic political and diplomatic consequences. Anyone interested in learning Antietam should begin by reading this book.
