The Royal Navy also controlled Royal Navy Beach Parties, based on teams formed to control the evacuation of Dunkirk in 1940. These were later known simply as RN Commandos, and they did not see action until they successfully fought for control of the landing beaches (as in the disastrous Dieppe Raid of 19 August 1942). The RN Commandos, including Commando "W" from the Royal Canadian Navy, saw action on D-Day.
