From the War Department marker at Antietam for September 16:

“In the general advance of the Ninth Corps on Sharpsburg, the Division moved on either side of the road from the bridge to the town until the center reached this elevation, when, the left flank of the Corps having been turned, the Division was withdrawn to the banks of the Antietam, where it remained until the evening of the 18th, when it was relieved by Morell’s Division of the Fifth Army Corps.”

“A section of the 8th Massachusetts Battery, under Lieut. John N. Coffin, accompanied the Division in its advance and went into position in Otto’s orchard about 350 yards south of this point.” (Rodman Avenue)

From the Marker for September 17:

“Willcox’s Division was the last to cross the Antietam. Passing over the stone bridge at 2 P.M., it moved up the road to this point and deployed… A section of the 8th Battery, Massachusetts Artillery, went into position in Otto’s orchard. A severe engagement took place, resulting in the expulsion of the Confederate Artillery and Infantry from Cemetery Hill and the adjacent heights overlooking Sharpsburg, and the Division skirmishers entered the streets of the town… The left of the Corps line being turned by the attack of A.P. Hill, Willcox’s Division, with its support, was withdrawn to this point (Old Burnside Bridge Road east of the Otto farm house) where it remained until the 18th, when it was relieved by Morell’s Division, Fifth Army Corps.”
