Ninth Army Corps

   About 3 P.M., Willcox's and Rodman's Divisions, with their supporting Brigades, advanced on Sharpsburg; Willcox following the road to the town, Rodman moving over the hill on his left.

The right of Willcox's was checked on the high ground east of the Sharpsburg Road; the left, passing a few yards east of this point, gained the stone mill and the house beyond and penetrated the orchard, Crook's Brigade moving up to this fence in support.

Rodman's advance passed this road about 500 yards southwest of this point and, swinging to the right to close up on Willcox, advanced about 360 yards north and west of this point, driving the Confederates from their position.

Rodman's left having been repulsed by the advance of A.P. Hill's Division, the whole line, after a contest in which all the Brigades of the Corps were engaged, was drawn back to the cover of the high ground bordering the Antietam.
