Operation Rumford was a British Commando raid during the Second World War. It was carried out over the night of 25/26 August 1944, by the Belgian No. 4 Troop of No. 10 (Inter-Allied) Commando who had returned to England in June and were selected to capture the French Isle of Yeu only to find during a reconnaissance that the Germans had already left.
