From the first of two position markers on the Antietam battlefield:
Archer’s Brigade formed line in the road at this point about 3 P.M. supported on the right by the Brigades of Branch and Gregg, and on the left by Toombs’ Brigade of D.R. Jones’ Division. It advanced through a narrow cornfield and across the broad ravine beyond to the stone wall about 600 yards distant, where it met and checked the left of the advancing Federal line. An attempt to advance farther was repulsed and the Brigade rallied behind the stone wall where it remained until early on the morning of the 19th when it recrossed the Potomac at Blackford’s Ford.
From the second of two position markers on the Antietam battlefield:
In its advance from the Antietam Furnace Road, West of this point, on the afternoon of September 17, 1862, Archer’s Brigade of A.P. Hill’s Division encountered the Federal troops posted behind the stone fence forming the western line of the 40 acre cornfield.
Gregg’s movements on the left flank of the Federal line having compelled it to retire, Archer’s Brigade charged over the fence and across the cornfield, but was repulsed with considerable loss and fell back to this side of the fence, where it remained until withdrawn to recross the Potomac on the morning of the 19th.

When the men of the 7th Tennessee who had advanced the farthest were cut off and about to be captured, Captain A.D. Norris ripped the flag from the staff and carried it to safety.
