Squadron. During the First World War the Newfoundland Royal Naval Reserve served with the regular navy and in 1916 the Calypso was renamed the H.M.S. Briton. Decline In the late 1930s, The Admiralty realised that the numbers available would not meet the needs of the fast approaching war and created the Royal Naval Volunteer Supplementary Reserve (RNVSR). The main recruits were amateur yachtsmen, who were given sufficient training to get them up to speed in a very high-pressure manner compared with the 'ordinary' RNVR. The RNVSR uniform was the same as the RNVR one. The RNVSR was dropped after World War II. Those who became officers during World War II were considered to have joined the RNVR and wore that service's uniform. Most of the officers in landing craft, Coastal Forces and the Atlantic Convoys were RNVR and many regular officers were astonished how well they coped. A significant number achieved command of corvettes and even frigates. Quite a few also went into the submarine branch of the service and some achieved command there, the first being Commander E.P. Young DSO, DSC and bar, who commanded HMS Storm. See also Royal Naval Patrol Service Royal Australian Naval Reserve Royal Australian Naval Volunteer Reserve References History of the Royal Navy
