Ragnar Colvin

Admiral Sir Ragnar Musgrave Colvin (1882–1954) was a long-serving British naval officer who commanded the Royal Australian Navy (RAN) at the outbreak of the Second World War.

Early life and background
Colvin was the son of Clement Sneyd Colvin and his wife Alice Jane, née Lethbridge. This connected him with a long and illustrious line of British Empire soldiers and administrators, the Colvin family; his grandfather was John Russell Colvin, lieutenant-governor of the North-West Provinces of British India during the mutiny of 1857. His uncles included Walter Mytton and Auckland, also lieutenant-governor of the North-West Provinces and Oudh. A first cousin, Brenda Colvin (1897–1981), was an important landscape architect, author of standard works in the field and a force behind its professionalization. A more distant cousin was Sidney Colvin, who grew up to be a critic, curator, and great friend of Robert Louis Stevenson.

Career
Colvin joined the Royal Navy as a cadet in HMS Britannia in 1896, was commissioned lieutenant six years later and, after qualifying as a gunnery specialist in 1904, was promoted Commander in 1913. In World War I he served as Executive Officer in the cruiser Hibernia, and in the battleship Revenge in which he served in the Battle of Jutland in 1916. Promoted Captain on 31 December 1917, he served in the Admiralty as Assistant Director of Plans and was appointed CBE.

After the war Colvin commanded the cruiser HMS Caradoc in the Black Sea and the Mediterranean and in 1922 to 1924 he was Naval Attaché in Tokyo. He re-joined HMS Revenge as Flag Captain to the Commander-in-Chief, Atlantic Fleet, and in 1927 became Director of the Naval Tactical School, Portsmouth. Colvin was promoted Rear Admiral in 1929 and soon was appointed Chief of Staff to the Commander-in-Chief, Atlantic Fleet. In 1932 he was appointed CB and posted to the 2nd Battle Squadron. Promoted Vice Admiral in 1934, he became president of the Royal Naval College, Greenwich, and commander of the Royal Naval War College. He was appointed KBE in 1937.

Colvin was appointed Chief of Naval Staff to the Royal Australian Navy in 1937. Under his leadership, the Royal Australian Navy expanded its naval fleet and maintained a high profile in Australia’s military affairs.

At the outbreak of World War II, Colvin was an active participant in international planning; however, by 1940 his health was failing and he resigned the following year. Colvin returned to London where he served as Naval Advisor to the Australian High Commission from 1942 to 1944.
