tained; which would have caused much greater delay than was required on the other route, where we could take provisions from the enemy. Moreover unless the Baltimore and Ohio railroad was torn up, the enemy would have been able to move troops from the West over that road to Washington.
On the night of the 2nd, McCausland was sent across North Mountain, to move down Back Creek, and burn the railroad bridge at its mouth, and then to move by North Mountain depot to Hainesville, on the road from Martinsburg to Williamsport; and, early on the morning of the 3rd, Bradley Johnson was sent by Smithfield and Leetown, to cross the railroad at Kearneysville, east of Martinsburg, and unite with McCausland at Hainesville, so as to cut off the retreat of Sigel, who was at Martinsburg with a considerable force. Breckenridge moved, on the same morning, direct for Martinsburg, with his command preceded by Gilmor's battalion of cavalry, while I moved, with Rodes' and Ramseur's divisions, over the route taken by Johnson, to Leetown. On the approach of Breckenridge, Sigel, after very slight skirmishing, evacuated Martinsburg, leaving behind considerable stores, which fell into our hands. McCausland burned the bridge over Back Creek, captured the guard at North Mountain depot, and succeeded in reaching Hainesville; but Johnson encountered a force at Leetown, under Mulligan, which, after hard fighting, he drove across the railroad, when, Sigel, having united with Mulligan, Johnson's command was forced back, just before night, on Rodes' and Ramseur's divisions, which had arrived at Leetown, after a march of twenty-four miles. It was too late, and these divisions were too much exhausted, to go after the enemy; and, during the night, Sigel retreated across the Potomac, at Shepherdstown, to Maryland Heights.
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
