Published here for the first time, the Civil War combat memoir of Lieutenant Colonel James Taylor Holmes of the 52nd Ohio Volunteers presents a richly detailed firsthand account of the action on Cheatham's Hill during the June 1864 Battle of Kennesaw Mountain. Written in 1915, Holmes' insightful narrative, with original hand-drawn diagrams, differs on key points from the accepted scholarship on troop movements and positions at Kennesaw, and contests the legitimacy of a battlefield monument. An extensive introduction and annotations by historian Mark A. Smith provide a brief yet comprehensive overview of the battle and places Holmes' document in historical context.
