Alternately barracks, battleground, and eventually burial place during the Civil War, the Mount Zion Old School Baptist Church near Aldie in Loudoun County, was also the site of one of Colonel John Mosby’s most famous fights. Union troops had been on the hunt for Mosby, on orders of the federal government, after a number of successes bolstered his fame. The troops had stopped to cook dinner at Mount Zion Church, when Mosby and his men encountered them there. During the ensuing battle, at least 105 Union soldiers were killed, wounded, or captured. Mosby lost only a single man. The burial sites of some of these Union soldiers are identified with blank fieldstone markers.
