A lithograph depicting the Battle of Fort Sanders, the decisive engagement of the 1863 Knoxville Campaign during the American Civil War. The Confederate army, under Lt. Gen. James Longstreet, attacked the Union salient of Fort Sanders. Although he had superior numbers, Longstreet planned poorly and was unable to break through the fort's defenses; he called off his attack after 20 minutes. The Union defenders, under Maj. Gen. Ambrose Burnside, suffered 13 casualties to the Confederates' 813.Lithograph: Kurz and Allison; restoration: Adam Cuerden
