September 17, 1862

At daylight of the 17th Nagle’s Brigade was about a half mile northeast of this point. It moved to the south and, at 10 A.M., was formed for assault on the bridge. The 2nd Maryland took position in the old lane 110 yards southeast of this point, and the remainder of the Brigade under cover of the hill and in rear of the 2nd Maryland. At 11 A.M. the 2nd Maryland, closely followed by the 6th New Hampshire, both moving by the flank, charged down the hill under a heavy fire of artillery and musketry. They passed through the opening in the fence at this point and reached within 250 feet of the bridge, when their advance was checked. Many of the men took shelter behind the fences and trees bordering the stream, and supported Ferrero’s Brigade in its successful assault. The Brigade then crossed the bridge, filed to the left, and occupied the high ground beyond. Late in the day it moved forward and co-operated in checking the advance of the right of A.P. Hill’s Division.

No. 69.
