William Oliver Churchill, DSO, MC (1914–1997) was a Special Operations Executive (SOE) officer during the Second World War. Shortly after the Italians had switched allegiance to the Allies in September 1943, he was parachuted into German occupied Corfu to inform the Italian commander that the Allies would support him. In August 1944, he was parachuted into northern Italy behind German lines to act as British Liaison Officer with the partisan leaders. He was the younger brother of Walter Churchill and Peter Churchill.
