Corvette

Corvette

A corvette is a small warship. It is traditionally the smallest class of vessel considered to be a proper warship. The warship class above the corvette is that of the frigate, while the class below was historically that of the sloop-of-war.

World War II

World War II

World War II or the Second World War, often abbreviated as WWII or WW2, was a global conflict that lasted from 1939 to 1945. The vast majority of the world's countries, including all of the great powers, fought as part of two opposing military alliances: the Allies and the Axis. Many participants threw their economic, industrial, and scientific capabilities behind this total war, blurring the distinction between civilian and military resources. Aircraft played a major role, enabling the strategic bombing of population centres and the delivery of the only two nuclear weapons ever used in war.

Battle of the Atlantic

Battle of the Atlantic

The Battle of the Atlantic, the longest continuous military campaign in World War II, ran from 1939 to the defeat of Nazi Germany in 1945, covering a major part of the naval history of World War II. At its core was the Allied naval blockade of Germany, announced the day after the declaration of war, and Germany's subsequent counter-blockade. The campaign peaked from mid-1940 through to the end of 1943.

Background

Main article: Flower-class corvette

Flower-class corvettes like Rimouski serving with the Royal Canadian Navy during the Second World War were different from earlier and more traditional sail-driven corvettes.[3][4][5] The "corvette" designation was created by the French for classes of small warships; the Royal Navy borrowed the term for a period but discontinued its use in 1877.[6] During the hurried preparations for war in the late 1930s, Winston Churchill reactivated the corvette class, needing a name for smaller ships used in an escort capacity, in this case based on a whaling ship design.[7] The generic name "flower" was used to designate the class of these ships, which – in the Royal Navy – were named after flowering plants.[8]

Corvettes commissioned by the Royal Canadian Navy during the Second World War were named after communities for the most part, to better represent the people who took part in building them. This idea was put forth by Admiral Percy W. Nelles. Sponsors were commonly associated with the community for which the ship was named. Royal Navy corvettes were designed as open sea escorts, while Canadian corvettes were developed for coastal auxiliary roles which was exemplified by their minesweeping gear. Eventually the Canadian corvettes would be modified to allow them to perform better on the open seas.[9]

Sir Winston Leonard Spencer Churchill was a British statesman, soldier, and writer who served as Prime Minister of the United Kingdom twice, from 1940 to 1945 during the Second World War, and again from 1951 to 1955. Apart from two years between 1922 and 1924, he was a Member of Parliament (MP) from 1900 to 1964 and represented a total of five constituencies. Ideologically an economic liberal and imperialist, he was for most of his career a member of the Conservative Party, which he led from 1940 to 1955. He was a member of the Liberal Party from 1904 to 1924.

Percy W. Nelles

Percy W. Nelles

Admiral Percy Walker Nelles, was a flag officer in the Royal Canadian Navy (RCN) and the Chief of the Naval Staff from 1 January 1934 to 15 January 1944. He oversaw the massive wartime expansion of the RCN and the transformation of Canada into a major player in the Battle of the Atlantic. During his tenure U-boats raided the Gulf of St. Lawrence, Canadian Northwest Atlantic command was created, and the RCN provided up to 40% of all escort forces in the North Atlantic. His handling of the RCN's war effort had its opponents however, and he was removed from his post as Chief of the Naval Staff in January 1944. He was sent to London as Overseas Naval Attaché, coordinating RCN operations for Operation Overlord. He retired in January 1945 as a full admiral.

Construction

Rimouski was ordered on 22 January 1940 as part of the 1939-1940 Flower-class building program. She was laid down at George T. Davie & Sons Ltd., Lauzon on 12 July 1940 and launched on 3 October 1940.[10] She was commissioned into the RCN on 26 April 1941 at Quebec City.[11]

Rimouski had her fo'c'sle extended during a refit at Liverpool, Nova Scotia that began in March 1943 and lasted until August. She had a second major refit from November 1944 until February 1945. That overhaul was begun at Louisburg, Nova Scotia but was completed at Halifax.[11]

Service history

After arriving at Halifax, Nova Scotia for deployment, Rimouski was initially assigned to Newfoundland Command as a convoy escort. Along with HMCS Pictou, she was one of the two first Canadian corvettes to escort an HX convoy in June 1941. She remained as part of Newfoundland Command until June 1942.

In June 1942, Rimouski joined the Western Local Escort Force. She remained with this force until March 1943 when she departed for her first significant refit. Upon her return to service, she was assigned to the Mid-Ocean Escort Force (MOEF) escort group C-1.[11] During that time Rimouski participated in RCN operations as part of Operation Pointe Maisonnette, the Canadian military's counter-offensive to the German military's Operation Kiebitz. Operation Kiebitz was a plan by the Kriegsmarine to have several senior naval officers (including Otto Kretschmer and Wolfgang Heyda) attempt to escape from the Camp 30 prisoner of war camp at Bowmanville, Ontario to rendezvous for a planned extraction by U-536 off Pointe de Maisonnette, New Brunswick on 26–27 September 1943.

Canadian military intelligence and police intercepted and decoded the encrypted Kriegsmarine instructions to its prisoners at Camp 30 and the RCN planned a response centred on an anti-submarine task force that would be hidden near the extraction point. Rimouski was outfitted with an experimental version of diffused lighting camouflage for the operation. Military guards were aware of the tunnelling efforts at Camp 30 but deliberately (and covertly) allowed them to proceed so as to not tip off the Kriegsmarine. Incidentally, Wolfgang Heyda did escape, however not by the tunnel as he used a zip wire on electrical cables to carry him outside the camp fence. He made his way by Canadian National Railways passenger trains to northern New Brunswick only to be apprehended by RCN and Canadian Army personnel on shore at the Pointe de Maisonnette lighthouse.

U-536 lurked offshore for the coded light signal from the escapees and the RCN personnel attempted to replicate what the escapees would have done, however the submarine detected the presence of the RCN task force led by Rimouski and remained submerged and evaded attack or capture, without successfully carrying the prisoners, but was sunk the following month by the Canadian frigate Nene and corvette Snowberry on 19 November 1943 while she was attacking Convoy SL 139/MKS 30.[12]

In December 1943, Rimouski transferred to MOEF escort group C-3. In April 1944, Rimouski joined Western Approaches Command after being allotted for invasion duties. She was one of 57 RCN warships that participated in Operation Neptune, the code name for the Normandy Landings as part of D-Day (Operation Overlord). On 31 May, she departed Oban to escort the blockships that were part of the constructed bridgehead on the beaches of Normandy. She remained in the English Channel escorting invasion convoys until August, when she returned to Canada.[11]

Upon her return to Canada, Rimouski briefly served as a training ship at Halifax, before undergoing her second major refit. After workups, she returned to the United Kingdom as a member of escort group EG 41 based in Plymouth. She spent the rest of the war as part of that unit.[11]

A common tradition of painting a mascot on a naval ship's gun shields, Rimouski featured a boisterous cowboy with a 10-gallon hat lassoing a U-boat from the back of his steed.

Rimouski was paid off on 24 July 1945 at Sorel, Quebec. She was sold for scrapping and broken up in December 1950 at Hamilton, Ontario.[2][11]

HX convoys

HX convoys

The HX convoys were a series of North Atlantic convoys which ran during the Battle of the Atlantic in the Second World War. They were east-bound convoys and originated in Halifax, Nova Scotia from where they sailed to ports in the United Kingdom. They absorbed the BHX convoys from Bermuda en route. Later, after the United States entered the war, HX convoys began at New York.

Western Local Escort Force

Western Local Escort Force

Western Local Escort Force (WLEF) referred to the organization of anti-submarine escorts for World War II trade convoys from North American port cities to the Western Ocean Meeting Point near Newfoundland where ships of the Mid-Ocean Escort Force (MOEF) assumed responsibility for safely delivering the convoys to the British Isles.

Mid-Ocean Escort Force

Mid-Ocean Escort Force

Mid-Ocean Escort Force (MOEF) referred to the organisation of anti-submarine escorts for World War II trade convoys between Canada and Newfoundland, and the British Isles. The allocation of United States, British, and Canadian escorts to these convoys reflected preferences of the United States upon their declaration of war, and the organisation persisted through the winter of 1942–43 despite withdrawal of United States ships from the escort groups. By the summer of 1943, United States Atlantic escorts were focused on the faster CU convoys and the UG convoys between Chesapeake Bay and the Mediterranean Sea; and only British and Canadian escorts remained on the HX, SC and ON convoys.

Operation Kiebitz

Operation Kiebitz

Operation Kiebitz was a failed German operation during World War II to organize the escape of four skilled U-boat commanders from a Canadian prisoner of war camp in Bowmanville, Ontario. The subsequent counter operation by the Royal Canadian Navy, Operation Pointe Maisonnette, became a key engagement in the Battle of the St. Lawrence and was also successful in thwarting the Germans' plan.

Diffused lighting camouflage

Diffused lighting camouflage

Diffused lighting camouflage was a form of active camouflage using counter-illumination to enable a ship to match its background, the night sky, that was tested by the Royal Canadian Navy on corvettes during World War II. The principle was discovered by a Canadian professor, Edmund Godfrey Burr, in 1940. It attracted interest because it could help to hide ships from submarines in the Battle of the Atlantic, and the research project began early in 1941. The Royal Navy and the US Navy carried out further equipment development and trials between 1941 and 1943.
