On the 4th, Shepherdstown was occupied by a part of Ransom's cavalry. Rodes' and Ramseur's divisions moved to Harper's Ferry, and the enemy was driven from Bolivar Heights, and the Village of Bolivar, to an inner line of works under the cover of the guns from Maryland Heights. Breckenridge, after burning the railroad bridges at Martinsburg, and across the Opequon, moved to Duffield's depot, five miles from Harper's Ferry, destroying the road as he moved.

At night, considerable stores, which had been abandoned at Harper's Ferry, were secured; and, before day, Rodes' and Ramseur's divisions moved to Shepherdstown, and crossed the Potomac early on the 6th, Lewis' brigade, of Ramseur's division, being left to occupy Harper's Ferry with skirmishers.
