—in rear of which last, after daylight, the cavalry was also to cross, except that Fitz. Lee's brigade, should he find the pontoon bridge clear in time, was to cross at the bridge; otherwise, to cross at the ford at Williamsport. The operation was successfully performed by the cavalry. General Fitz. Lee, finding the bridge would not be clear in time for his command, moved after daylight to the ford, sending two squadrons to cross in rear of the infantry at the bridge. These squadrons, mistaking Longstreet's rear for the rear of the army on that route, crossed over in rear of it. General Hill's troops, being notified that the squadrons would follow in his rear, were deceived by some of the enemy's cavalry, who approached very near in consequence of their belief that they were our cavalry.

Harper's Ferry was again in possession of the enemy, and Colonel Harman, Twelfth Virginia cavalry, had in an engagement with the enemy gained a decided success, but was himself captured by his horse falling.
Upon my arrival at the Bower that afternoon (15th), I learned that a large force of the enemy's cavalry was between Shepherdstown and Leetown, and determined at once to attack him, in order to defeat any designs he might have in the direction of Martinsburg. I made disposition accordingly, concentrating cavalry in his front, and early on the 16th moved Fitz. Lee's brigade down the turnpike towards Shepherdstown, supported by Chambliss, who, though quite ill, with that commendable spirit which has always distinguished him, remained at the head of his brigade. Jenkins' brigade was ordered to advance on the road from Martinsburg towards Shepherdstown, so as by this combination to expose one
