This SOE mission, requested by the Air Ministry, was to ambush and kill as many pilots as possible of the Kampfgruppe 100, a German Pathfinder formation stationed at Meucon airfield which spearheaded night raids on Britain.

The following day they discovered the pilots no longer commuted between Vannes and Meucon by bus, but had taken to travelling on an ad hoc basis by cars.

Seeking to gain something from the mission, Captain Georges Bergé instructed his men to disperse and go on general reconnaissance and meet at Sables d'Olonne at the end of the month for extraction by sea.

After several nights watching from the sand dunes, on 4/5 April, Bergé saw Geoffrey Appleyard of the SOE's Small Scale Raiding Force paddling ashore after launching from the submarine HMS Tigris.

Joël Le Tac remained behind and made his way to a safehouse in Paris and continued as an SOE operative.
