Due to their specialised skills, parties from the Royal Naval Commandos took part in every amphibious operation carried out by Allies from early 1942 to the end of the war. Following their initial involvement in Operation Ironclad on Madagascar, the next major operation that the Royal Naval Commandos were involved in came in August 1942, when two Royal Naval Commandos units—'C' and 'D'—were involved in the ill-fated Operation Jubilee. The units provided a beachmaster and beach party to each of the landing beaches, however, in the end many of the parties were unable to get ashore, while those that managed to land were prevented from carrying out their assigned tasks due to the high volume of machine gun fire directed on the beaches from the Germans defending them. As a result casualties among the naval commandos were high and when the operation was eventually abandoned, many of them were captured.
