In 2018 my wife and I toured the Civil War battlefield in Perryville, Kentucky. After viewing the visitor center videos, we purchased Christopher Kolakowski’s excellent book “The Civil War at Perryville: Battling for the Bluegrass.” His book is part of the Civil War Sesquicentennial Series; and has been reprinted six times from 2009-12. During day one of the fighting, within 5 hours, there were over 7,500 casualties —the largest per hour casualty count during the entire Civil War. According to The author, Perryville was both a strategic Union victory and a tactical win for the Confederacy. As a result of the battle, Kentucky remained a Union state. (P)
