(September 17, 1862.)

Manning’s Brigade reached Sharpsburg on the afternoon of September 16 and was held in reserve until daybreak of the 17th, when it took position opposite Snavely’s Ford on the Antietam, one and a half miles from town. Between 8 and 9 A.M., it moved to the left and supported McLaws in his attack on the enemy in the West Woods. Arriving on the rise of ground 300 yards west of this point, the 3d Arkansas and 27th North Carolina formed to hold the open space between the West Woods and the left of D.H. Hill’s Division east of this road. The remainder of the Brigade advanced on the right of Ransom’s Brigade to and beyond the road at the Dunkard Church, where it was repulsed. The 3d Arkansas and 27th North Carolina co-operated in expelling Greene’s Division from the woods about the church, after which they crossed the road and advanced through the fields to the east, but were repulsed and resumed their original position and were not again engaged.

No. 367.
