DFC citation - London Gazette 01st July 1941

P/O. John Winston Sievers:

"One night in June, 1941, this officer was the captain of an aircraft which, took part in an attack on Brest. In spite of intense anti- aircraft fire both from ground defences and ships, P/O. Sievers descended to 4,500 feet and skilfully dropped all his bombs in the target area. On a previous occasion, during an attack on Hamburg, this officer displayed great flying skill which enabled his rear gunner to shoot down a Messerschmitt which attacked his aircraft whilst held in the beams of searchlights. P/O. Sievers has completed many operational missions over enemy and enemy occupied country and has shown great skill and coolness throughout".
