Falling Waters Road south of Williamsport, Maryland is the site of the last Confederate defenses of their Potomac River crossing back into Virginia after the Gettysburg Campaign. The Donnelly House, near where Confederate Gen. Pettigrew was mortally wounded, still stands. Information about the area during the Civil War and the nearby Chesapeake and Ohio Canal is available at the Visitor's Center in Williamsport. Interpretive waysides along the canal towpath there detail the Confederate army's escape across the river. Separately, several historic markers on the West Virginia side of the river detail the July 1861 action at Falling Waters.
