Operation Bigamy aka Operation Snowdrop was a raid during the Second World War by the Special Air Service in September 1942 under the command of Lieutenant Colonel David Stirling and supported by the Long Range Desert Group. The plan was to destroy the harbour and storage facilities at Benghazi and raid the airfield at Benina in Libya in coordination with the RAF. The raid was part of a deception plan for Operation Agreement, the much larger raid on Tobruk.
