caption_attribution_description: English: Canadian destroyer HMS Ottawa (H60). She was originally the Royal Navy C class destroyer HMS Crusader (H60) from 1932-1938.
context_page_description: The C and D class was a group of 14 destroyers built for the Royal Navy in the early 1930s. As in previous years, it was originally intended to order a complete flotilla comprising eight destroyers—plus a flotilla leader as the ninth unit—in each year. However, only four ships—plus a leader—were ordered under the 1929–30 Programme as the C class. The other four ships planned for the C class were never ordered as an economy measure and disarmament gesture by the Labour government of Ramsay MacDonald. A complete flotilla—the 'D' class—was ordered under the 1930–31 Programme.
  The five ships of the C class were assigned to Home Fleet upon their completion, although they reinforced the Mediterranean Fleet during the Italian invasion of Abyssinia of 1935–36 and enforced the Non-Intervention Agreement during the Spanish Civil War of 1936–39. They were transferred to the Royal Canadian Navy in 1937–39 and spent most of their time during World War II on convoy escort duties in the Atlantic Ocean. Crescent was sunk when she was accidentally rammed by the British cruiser HMS Calcutta in 1940. Crusader was sunk by a German submarine in 1942, though she had sunk an Italian submarine in 1940.
context_section_description: All five of the C class were assigned to the 2nd Destroyer Flotilla of the Home Fleet upon commissioning during 1932. Following the Italian invasion of Abyssinia, the entire flotilla was sent to the Red Sea in August 1935 to monitor Italian warship movements until April 1936. Refitted upon their return, they were deployed to Spanish waters during the Spanish Civil War in 1936–37 to intercept shipping carrying contraband goods to Spain and to protect British-flagged ships. Crescent and Cygnet were sold to the Royal Canadian Navy in 1937 and Comet and Crusader in 1938. Kempenfelt was bought in 1939, but the Royal Navy did not turn her over until enough auxiliary anti-submarine ships had been commissioned to replace her after World War II had started. All four 'C'-class ships were stationed at Esquimalt in British Columbia when the war began, but only Fraser and St. Laurent were immediately recalled to begin convoy escort duties on the Atlantic Coast, the other two following in November. Assiniboine was sent to the Caribbean for local escort duties in December where she assisted in the capture of the blockade runner MV Hannover in March 1940. Fraser, St. Laurent, and Restigouche were transferred to the UK in late May and helped to evacuate refugees from France. Fraser was sunk on 25 June 1940 in a collision with the anti-aircraft cruiser HMS Calcutta in the Gironde estuary while the other two were assigned to the Western Approaches Command for escort duties.
  The remaining ships spent most of the rest of the war escorting convoys in the North Atlantic, based in either Canada or the UK. Ottawa assisted the British destroyer Harvester in sinking the Italian submarine Comandante Faà di Bruno on 7 November 1940. She was sunk by the German submarine U-91 on 14 September 1942 while escorting Convoy ON 127. St. Laurent had her first victory on 27 December 1942 when she was credited with sinking U-356 while defending Convoy ON 154. Together with the destroyer HMS Forester, and the frigates HMCS Owen Sound and HMCS Swansea, she sank U-845. While escorting Convoy SC 94 on 3 August 1942, Assiniboine rammed and sank U-210. Restigouche never sank a submarine, but she and St. Laurent were transferred to the UK to protect the shipping mustering for Operation Overlord in May 1944 and Assiniboine followed in July. They saw some action against German patrol boats in the Bay of Biscay, but Restigouche and St. Laurent were in poor shape by this time and were sent back to Canada for lengthy refits in late 1944. They remained in Canada after the completion of their refits in early 1945, while Assiniboine remained in the UK until June. All three ships transported Canadian troops home after VE Day until they were decommissioned in late 1945. All three were broken up in 1946–47.
  Upon commissioning in 1932–33, the D class formed the 1st Destroyer Flotilla assigned to the Mediterranean Fleet. The flotilla toured the Persian Gulf and the Red Sea in September–November 1933. After refitting in the UK during 1934, the flotilla was transferred to the China Station, arriving at Hong Kong in January 1935 and renumbered as the 8th Destroyer Flotilla. Most of the flotilla was sent to the Red Sea during the Italian invasion of Abyssinia in 1935–36. They returned to the Hong Kong in mid-1936 and remained there until World War II began. Diamond was in the midst of a refit that lasted until November, but the rest of the flotilla was immediately transferred to the Mediterranean Fleet. Daring was kept in the Red Sea for escort duties until November, but the rest of the flotilla was used on contraband patrol duties upon arrival. They all needed repairs which were made before the end of the year.
  Duncan, Diana, Duchess, Delight and Daring were transferred to the Home Fleet in December 1939, although Duchess was rammed and sunk on 10 December by the battleship Barham that she was escorting. Duncan was so badly damaged in a collision with a merchant ship in January 1940 that her repairs required six months to complete. Daring was sunk by the German submarine U-23 on 18
