Hasler and Sparks began at about 21:00 on 11 December and placed eight limpet mines on four vessels. One target was a Sperrbrecher, where a sentry shone a torch toward the water without finding their canoe. They continued working around the harbour until about 01:00. Laver and Mills found no targets in their assigned eastern area and moved to Bassens, where they attached five mines to a large cargo ship and three to a small liner. The two crews met again near an island and paddled together until about 06:00 before setting off separately toward Spain. French gendarmes apprehended Laver and Mills two days later and handed them to the Germans.
