In the 1840s, engineers blasted through 175 feet of earth and bedrock at Allatoona Pass, Georgia, to allow passage of the Western & Atlantic Railroad. Little more than twenty years later, both the Union and Confederate armies fortified the hills and ridges surrounding the gorge to deny the other passage during the Civil War. In October 1864, the two sides met in a fierce struggle to control the iron lifeline between the North and the recently captured city of Atlanta. Though small compared to other battles of the war, this division-sized fight produced casualty rates on par with or surpassing some of the most famous clashes. Join author Brad Butkovich as he explores the controversy, innovative weapons and unwavering bravery that make the Battle of Allatoona Pass one of the war's most unique and savage battles.
