HMS Crescent (1931)

HMS Crescent was a C-class destroyer which was built for the Royal Navy in the early 1930s. The ship was initially assigned to the Home Fleet, although she was temporarily deployed in the Red Sea and Indian Ocean during the Abyssinia Crisis of 1935–36. Crescent was sold to the Royal Canadian Navy in late 1936 and renamed HMCS Fraser. She was stationed on the west coast of Canada until the beginning of World War II when she was transferred to the Atlantic coast for convoy escort duties. The ship was transferred to the United Kingdom (UK) in May 1940 and helped to evacuate refugees from France upon her arrival in early June. Fraser was sunk on 25 June 1940 in a collision with the anti-aircraft cruiser HMS Calcutta (D82) while returning from one such mission.

Design and construction
Crescent displaced 1375 LT at standard load and 1865 LT at deep load. The ship had an overall length of 329 ft, a beam of 33 ft and a draught of 12 ft. She was powered by Parsons geared steam turbines, driving two shafts, which developed a total of 36000 shp and gave a maximum speed of 36 kn. Steam for the turbines was provided by three Admiralty 3-drum water-tube boilers. Crescent carried a maximum of 473 LT of fuel oil that gave her a range of 5500 nmi at 15 kn. The ship's complement was 145 officers and men.

The ship mounted four 45-calibre 4.7-inch Mk IX guns in single mounts, designated 'A', 'B', 'X', and 'Y' from front to rear. For anti-aircraft (AA) defence, Crescent had a single QF 3-inch 20 cwt AA gun between her funnels, and two 40 mm QF 2-pounder Mk II AA guns mounted on the aft end of her forecastle deck. The 3 in AA gun was removed in 1936 and the 2-pounders were relocated to between the funnels. She was fitted with two above-water quadruple torpedo tube mounts for 21-inch torpedoes. Three depth-charge chutes were fitted, each with a capacity of two depth charges. After World War II began this was increased to 33 depth charges, delivered by one or two rails and two throwers.

Crescent was ordered on 30 January 1930 as part of the 1929 Naval Programme and laid down on 1 December 1930 at Vickers-Armstrongs, Barrow-in-Furness. She was launched on 29 September 1931 and completed on 15 April 1932.

Operational history
After the ship commissioned on 21 April 1932, she was assigned to the 2nd Destroyer Flotilla of the Home Fleet. Crescent collided with her sister HMS Comet (H00) at Chatham on 21 July and was under repair until 27 August. Crescent was refitted at Chatham between 30 March and 6 May 1933, before deploying to the West Indies between January and March 1934. She was given another refit at Chatham from 27 July to 3 September 1934. Crescent was detached from the Home Fleet during the Abyssinian Crisis, and deployed in the Indian Ocean and the Red Sea from September 1935 to April 1936. When the ship returned, she was refitted at Sheerness between 23 April to 13 June and placed briefly in reserve.

Transfer to the Royal Canadian Navy
Together with her sister HMS Cygnet (H83), Crescent was sold to Canada on 20 October 1936 for a total price of £400,000. She was refitted again to meet Canadian standards, including the installation of ASDIC (sonar), and taken over by them on 1 February 1937. The ship was renamed as HMCS Fraser and commissioned into the RCN at Chatham on 17 February. Fraser was assigned to the Canadian Pacific Coast and arrived at Esquimalt on 3 May 1937. She remained there until she was ordered to the East Coast on 31 August 1939.

When World War II began on 3 September, Fraser was transiting the Panama Canal and arrived at Halifax on 15 September. She and her sisters were employed as local escorts to ocean convoys sailing from Halifax. In November the Royal Navy's North America and West Indies Station took operational control of the Canadian destroyers. The ship escorted the convoy bringing most of the 1st Canadian Infantry Division to Britain part way across the North Atlantic in mid-December. In March 1940 she was ordered to join the Jamaica Force for Caribbean patrols before being reassigned to Western Approaches Command two months later. On 26 May she left Bermuda for Britain and arrived at Plymouth on 3 June where she was pressed into service evacuating Allied troops from various French ports on the Atlantic coast. Sometime in 1940, the ship's aft set of torpedo tubes was removed and replaced by a 4 in AA gun.

Loss
On 25 June 1940, Fraser, her sister HMCS Restigouche (H00), and the cruiser Calcutta were returning from St. Jean de Luz after rescuing refugees trapped by the German Army (Operation Aerial), when Fraser was rammed by Calcutta in the Gironde estuary. Struck forward of the bridge by the cruiser's bow, Fraser was cut in half and sank immediately. All but 45 of the ship's crew were rescued by Restigouche and other nearby ships. Many of the survivors from Fraser transferred that later summer to HMCS Margaree (H49), and were lost when that vessel sank on 22 October 1940 as a result of a collision with the freighter MV Port Fairy.
