The two photographs on Page 7 were taken by an RE8 of 6 Squadron, part of the squadron's aerial reconnaissance operations over the Western Front during WW1.

​

Both photographs of Page 7 were shot by the crew of a 6 Squadron RE8 over the town of St Eloi, as defined by the mapping coordinates 28. O. 2. C and 28. O. 2. B, each area measuring 500 yards square. This was a prime example of a 6 Squadron WW1 aerial reconnaissance operation. The first photograph was taken on the 18th May 1917 and the second on the 11th June 1917, 4 days after the 19 mines were detonated beneath the German lines along the Messines ridge.
