From the War Department tablet at Antietam:

Anderson’s Brigade advanced from the North Woods about 6:30 A.M. in support of Doubleday’s Division engaged on either side of the road south of this point. Midway between the North Woods and D. R. Miller’s, the 10th Regiment crossed the road and moving west about 700 yards became engaged with the enemy’s skirmishers and the Artillery of Stuart’s Cavalry Command. The three remaining Regiments formed line with the right resting on the road at this point. A charge of the enemy to the north edge of the Cornfield was repulsed and the Brigade advanced to the Cornfield, the 9th Regiment going through the corn to its south edge, the center and left about midway into the corn, when it was checked by the advance of a Confederate line and fell back, after which Anderson withdrew to the North Woods, where he was rejoined by the 10th Regiment and served as a rallying point for Sedgwick’s Division, Second Corps. The Brigade then moved to the rear of the high ground north of Joseph Poffenberger’s.

The regiment lost 13 killed, 47 wounded and 4 missing.
