Battle of Folck's Mill

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.

After burning Chambersburg, Pennsylvania, on July 30, cavalry under Confederate generals John McCausland and Bradley T. Johnson set out for western Maryland towards Cumberland, to disrupt traffic on the Baltimore and Ohio (B&O) Railroad and to demand a ransom from the town or torch it as well. At 3 p.m. on August 1, the Confederates arrived at Folck's Mill, east of Cumberland. There, Union Brig. Gen. Benjamin F. Kelley, with three regiments of untested "100-days" troops and six pieces of artillery, met the Confederate advance. As the Confederates arrived at the outskirts of town, Kelley's artillery fired on the cavalry. Lacking familiarity with the local terrain and the strength of the force he was up against, McCausland decided against an assault and brought up his own artillery. The gunners from both armies dueled until about 8 p.m., at which point McCausland withdrew, heading southeast to Old Town on the Potomac River.

The following day the Confederates prepared to cross the Potomac and head into West Virginia but found the bridges over the Chesapeake and Ohio Canal had been burned by Col. Israel Stough and his regiment of 100-days troops. Stough deployed his force on the spit of land between the canal and river to contest the Confederate advance toward the river. After initially repulsing a charge by the Confederate cavalry, Stough was forced to retreat across the Potomac when the 21st Virginia successfully constructed a bridge and crossed the canal on his left flank. On the south bank of the river the Federals took cover in a blockhouse on the B&O Railroad and in an armored ordnance train operated by the Potomac Home Brigade that was stopped on the line. McCausland briefly considered an all out charge on the blockhouse, but then thought it wise to first demand its surrender. The Federals in the blockhouse agreed to the terms of surrender, and the Confederates crossed the river and headed to Springfield, West Virginia, where they rested until the 4th.

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.
