The Breakthrough, the Union Collapse, and the Defense of Horseshoe Ridge, September 20, 1863 Now in paperback, Glory or the Grave is the second volume in The Chickamauga Campaign, David Powell’s magnificent three-volume study of this overlooked and often misunderstood campaign. For any student of the Civil War in general, or the Western Theater in particular, Powell’s trilogy is a must-read. AUTHOR: David A. Powell is a 1983 graduate of the Virginia Military Institute with a B.A. in history. After graduating from VMI, he went to work for CBS Messenger-a family business in the Chicago area-but never lost his intense interest in military history, especially in the American Civil War. David has written numerous articles for a variety of magazines, more than fifteen historical simulations of various battles, and regularly leads tours of the Chickamauga battlefield. His previous books include The Maps of Chickamauga: An Atlas of the Chickamauga Campaign, Including the Tullahoma Operations, June 22 - September 23, 1863 (2009), and Failure in the Saddle: Nathan Bedford Forrest, Joseph Wheeler, and the Confederate Cavalry in the Chickamauga Campaign (2010), the recipient of the Atlanta Civil War Round Table’s Richard B. Harwell Award.
