Hill's five brigades were encamped at and around Boonsboro to prevent the escape of the Union forces at Harper's Ferry, through Pleasant Valley. Informed that two Union brigades were approaching Turner's Pass, Hill, on the evening of September 13, ordered Colquitt's and Garland's Brigades from Boonsboro, to dispute the passage of the mountain. Colquitt, with Lane's battery of Georgia Artillery, moved nearly to the east foot of the mountain and formed north of this road. During the night Garland's brigade and Bondurant's Alabama battery took position a few yards east of this. The Fourth Georgia of Ripley's brigade was ordered to guard Hamburg Pass, nearly three miles north. Early on the morning of the 14th Col. T.L. Rosser, with the 5th Virginia Cavalry and Pelham's Battery occupied Fox's Gap one mile south of this, traversed by the old Sharpsburg Road. Upon the approach of the Union advance by the Sharpsburg Road, Garland moved South along the crest of the mountain and joined Rosser. Colquitt moved back and formed line across the road about 700 yards southeast of this point. Lane's battery took the position a few feet north of this point. George B. Anderson's brigade was ordered to support Garland. Later in the day, Rodes occupied prominent peaks of the mountain north of this, commanding the approaches by the Old Hagerstown Road, and three regiments of Ripley's Brigade were ordered to follow George B. Anderson to the right.
