These orders stated that a "“small party of approximately twelve officers and men will be disembarked from the submarine in the vicincity of the mouth of the Gironde estuary. The party will paddle up to the Bassen-Bordeaux area in Cockles Mark II, where they will carry out a limpet attack on the blockade runners in the port”".
