Ninth Army Corps

Brig. Gen. Jacob D. Cox, Commanding.
September 15-16, 1862.

The Ninth Corps moved from Fox's Gap in South Mountain by the Sharpsburg Road, on the morning of September 15 and in the evening encamped in rear of the extreme left of the Army of the Potomac under the crest of the ridge opposite the Middle Antietam Bridge.

On the morning of the 16th the Corps moved to the left and took position upon the rear slopes of the ridges on the east bank of the Antietam, the center nearly opposite the Burnside Bridge.

Benjamin's Battery (E, 2d U.S. Artillery) occupied the knoll commanding the bridge; the remaining batteries of the Corps were in reserve under the cover of the ridge. During the 16th Benjamin's Battery engaged the Confederate Batteries posted on Cemetery Hill.

In the afternoon the battery moved a short distance south; Crook's Brigade on its right rear, supported by Sturgis' Division, and Rodman's Division on its left rear with Scammon's Brigade in support. Willcox's Division formed a third line in reserve.
