The Duke of York and Albany's Maritime Regiment of Foot, later to be known as the Royal Marines, is established.

The Royal Marines provide the United Kingdom's amphibious special operations capable commando force, one of the five fighting arms of the Royal Navy, a company strength sub-unit to the Special Forces Support Group (SFSG), landing craft crews, and the Naval Service's military bands. The Royal Marines trace their origins back to the formation of the "Duke of York and Albany's maritime regiment of Foot" on 28 October 1664, and the first Royal Marines Commando unit was formed at Deal in Kent on 14 February 1942 and designated "The Royal Marine Commando".
