Battle of Antietam

The 27th Indiana Infantry Regiment lost 41 killed and 168 wounded out of 443 men engaged during intense fighting in the Cornfield.

From the first War Department marker to Gordon’s Brigade in The Cornfield on the Antietam battlefield:

Gordon’s Brigade formed line at daybreak on the Hoffman farm and advanced in a southerly direction in support of Hooker’s Corps.

The 107th New York was detached to support Cothran’s Battery and the 13th New Jersey was held in reserve. The Brigade formed on either side of Ransom’s Battery on the high ground due east of D. R. Miller’s, where it repulsed an assault of Hood’s Division and its support and, moving south through the Cornfield, changed front to the right and took position behind the ridge parallel to the Hagerstown Pike, where it remained until it was relieved by the advance of Sedgwick’s Division and withdrawn to the East Woods.

From the second War Department marker to Gordon’s Brigade on the Antietam battlefield:

Immediately after the withdrawl of Gordon’s Brigade to the East Woods, after being relieved by Sedgwick’s Division, it was ordered to the support of that Division in the West Woods.

The 13th New Jersey and 2nd Massachusetts advanced into this road – the former north and the latter south of this point – where they encountered such a destructive fire from the enemy that they were compelled to retire to the East Woods. Later in the day, the 13th New Jersey advanced into the woods west of the Dunkard Church and took position on the right of Greene’s Division.
