This book provides new insights into the bloodiest day of the Civil War.The Maryland campaign of September 1862 ranks among the most important military operations of the American Civil War. The climactic clash came on September 17 at the battle of Antietam, where more than 23,000 men fell in the single bloodiest day of the war. Exploring topics related to Lee's and McClellan's operations from a variety of perspectives, contributors to this volume examine questions of military leadership, strategy, and tactics; the performance of untried military units; and the ways in which the battle has been remembered. The contributors are William A. Blair, Keith S. Bohannon, Peter S. Carmichael, Gary W. Gallagher, Lesley J. Gordon, D. Scott Hartwig, Robert E. L. Krick, Robert K. Krick, Carol Reardon, and Brooks D. Simpson. The editor is Gary W. Gallagher.
