Irwin's Brigade, Smith's Division

   About 5 P.M., the 7th Maine, on the left of the Brigade, crossed Mumma's Lane, moved obliquely across the front of Brook's Brigade, charged over the Bloody Lane at this point, dispersed the Confederates in its front and in the orchard on its left and reached the low ground North of Piper's Barn, when the enemy from behind the stone fence on the Hagerstown Pike and the hill adjoining poured a severe fire on its right flank and front.

The regiment then obliqued to the left, passed through an opening in the fence into the orchard and to within 70 yards of Piper's House, here it was met by a withering fire from a column of the enemy moving down the hill east of the house and driven back through the orchard with great loss.

It reformed a short distance east of this point and returned to the position from which it had advanced.

At noon of the 18th, the Brigade was relieved by Cochrane's Brigade of Couch's Division.
