The Battle of Folck's Mill, also known as the Battle of Cumberland, was a small cavalry engagement, fought August 1, 1864, in northern Maryland, as part of the Valley Campaigns of 1864 during the American Civil War. Although the action around Cumberland was tactically inconclusive, Kelley's stand likely saved the town from being burned and greater damage being inflicted on the railroads. The stubborn resistance of Stough at the Potomac represented the first time McCausland's force had been contested since burning Chambersburg.
