Drawing from The War Illustrated, 19 June 1915. Caption reads:

The Great Aerial Exploit of Lieut. Warneford: For skill and daring the magnificent exploit of Flight Sub-Lieut. Warneford, V.C., has rarely been equalled. While flying at a great height between Bruges and Ghent he encountered a Zeppelin. Quickly rising above it, he swooped down and launched bombs on the massive airship. A loud explosion followed, and the Zeppelin caught fire and fell to earth. The explosion caused the British machine to turn several somersaults, during which the petrol escaped from the rear tank and the pilot had to descend in the German lines. He managed to refill the empty tank, restart his engine, soar again into the air, and return safely to the British lines. Within thirty-six hours after his heroic deed the King had conferred the V.C. on the young aviator.
