After the Battle of Perryville in October 1862, the focus of the Civil War in the West shifted back to Tennessee. The Union Army of the Cumberland regrouped in Nashville, while the Confederate Army of Tennessee camped 30 miles away in Murfreesboro. On December 26 the Federals marched southward and fought a three-day brawl at Stones River with their Confederate counterparts. The Confederates withdrew, and both armies spent the winter and spring harassing each other and regrouping for the next round. In the Confederate camp, dissention corroded the army's high command. The book will use letters, reports, memoirs, and other primary sources to tell the story of the battles for Middle Tennessee in late 1862 and 1863. The critical engagement at Stones River (by percentage of loss the Civil War's bloodiest battle) and the masterful Tullahoma operation will receive detailed attention
