At Point of Rocks, Union troops on the Maryland side skirmish with Confederate units across the Potomac
Troops of the 28th Pennsylvania under Colonel John White Geary engaged several hundred Confederate troops dug in on the opposite Virginia side of the Potomac River. Rifle fire and artillery managed to drive away the Confederates and Pennsylvania troops crossed the river briefly and burned the houses their opponents had been using for cover. Few casualties were reported on either side. (By John Osborne)
