Commanders of Antietam, the Union and Confederate Commanders at the Battle of Antietam is a comprehensive look at the biographies of both armies' high command during the Maryland Campaign of September 1862. This treatment focuses on the lives of Union and Confederate commanders from the brigade level up to the army commanders, Robert E. Lee and George B. McClellan. Each commander's biography is broken into three sections: Before the Maryland Campaign; During the Maryland Campaign; and After the Maryland Campaign. This is the most complete volume of commanders' biographies in the Maryland Campaign. This book has been written by a collaboration of Antietam Battlefield Guides, National Park Service Rangers and volunteers, and Civil War historians. Kevin Pawlak and Brad Gottfried are the editors of this volume. It is the third in a series of books focused on different aspects of the campaign, including Brigades of Antietam (edited by Bradley Gottfried) and Artillery of Antietam (by James A. Rosebrock), both published by the Antietam Institute.
