All was not quiet along the Potomac early in 1862. The 28th Pennsylvania Volunteer Regiment, under command of Colonel John W. Geary of Kansas fame, was guarding a 24-mile stretch of the river, and there were occasional skirmishes between the opposing armies. On February 7, Geary shelled Harpers Ferry, and a few weeks later marched in and recaptured the town from the Confederates.
