Operation Loyton was the codename given to a Special Air Service (SAS) mission in the Vosges department of France during the Second World War. The mission, between 12 August and 9 October 1944, had the misfortune to be parachuted into the Vosges Mountains, at a time when the German Army was reinforcing the area, against General George Patton's Third Army. As a result, the Germans quickly became aware of their presence and conducted operations to destroy the SAS team.
