On September 17, 1862, French's Division followed Sedgwick across the Antietam and, after reaching the East Woods, wheeled left, drove Confederate outposts from the Roulette Buildings, and about 9:30 a.m. engaged the brigades of Rodes, Colquitt, and Garland. Posted on the west end of Bloody Lane, Geo. B. Anderson's Brigade, on Rodes' right, tried to turn French's left but was forced back by the advance of Richardson's Division, which formed on French's left. Five brigades of R.H. Anderson's Confederate division came to aid the four brigades already engaged. About noon French and Richardson carried Bloody Lane and the high ground immediately south of it. The Confederates then retreated to and beyond Piper's. Meanwhile Pleasonton's cavalry crossed the Antietam by the Middle Bridge and, advancing on the Boonsboro Pike, drove in Confederate skirmishers. Four horse batteries followed and were placed on the ridge crossing the pike about 880 yards southeast of this location, where they engaged Confederate artillery on Cemetery Hill. The horse batteries were relieved at intervals by two batteries of Sykes' Division. After noon portions of Sykes' regular division crossed the Antietam and, in cooperation with Ninth Corps, compelled the Confederate artillery to abandon Cemetery Hill. About 5 p.m. the Seventh Maine Infantry charged across Bloody Lane at a point about 450 yards west of this location and reached the Piper Barn but was soon driven back with great loss.
