Assured that no considerable body of Federal troops was approaching from the west, Hill's detachment was called back to Winchester. Some rough gunstocks having been left at Harper's Ferry, Lieut.-Col. G. H. Steuart was sent, with his Maryland battalion, to bring these away, which he did, leaving nothing there worth removing.
