Aerial Shot of Battlefield
This Information was provided by Robert Dunlop -
The photograph is rotated circa 110 degrees clockwise. Thus, north is roughly on the right hand side. The oval feature top-left is Essex Farm. Nearby is Subsidiary Trench. The rectangular feature mid-bottom right is Moated Farm. Just to the left of Moated Farm is a small dark splodge - this is Dead Horse Corner.
Messines is 2.5km north of Moated Farm.
