Flt. Sub-Lieut. Charles Philip Oldfield Bartlett, R.N.A.S.
   For exceptionally good work on the occasion of a bombing raid on Houttave Aerodrome on the 25th July, 1917.
Supplement to the London Gazette, 14 September 1917

Flt. Cdr. Charles Philip Oldfield Bartlett, D.S.C. [Distinguished Service Cross], R.N.A.S. {Royal Naval Air Service]
   For conspicuous bravery and devotion to duty in carrying out bombing raids and in attacking enemy aircraft.
    On the 28th March, 1918, he carried out three bombing raids. Whilst returning from one of these missions he was attacked at a height of about 2,500 feet by three enemy triplanes, and five other scouts. One of these he drove down, attacking it with his front guns, whilst his observer shot down out of control a second. Observing that two of the triplanes were diving on him and converging, he side-slipped his machine away with the result that the two enemy machines collided and fell to the ground together, where they burst into flames.
    He has carried out very many bombing raids, and brought down several enemy machines, invariably showing the greatest skill and determination.
