This wartime view of the Sunken Road shows the aftermath of the middle region of the field only days after the battle. This image demonstates the trench-like nature of the road. The postion shown here would have been occupied by Anderson's Brigade.
The trampled stacks of the Piper Cornfield are visible on the other side of the road. Although there are no close up pictures of the Miller 30 Acre Cornfield, one might conjecture that it was reduced to an appearance like this.
