Archer’s Brigade

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the cornfield, but was repulsed with considerable loss and fell back to this side of the fence, where it remained until withdrawn to recross the Potomac on the morning of the 19th.
