HMCS Fergus (K686)

HMCS Fergus was a modified Flower-class corvette that served with the Royal Canadian Navy during the Second World War. She fought primarily in the Battle of the Atlantic as a convoy escort. She was named for Fergus, Ontario. She was originally named Fort Frances but was renamed before launching. She was the last corvette launched by the Royal Canadian Navy.

Background
Flower-class corvettes like Fergus serving with the Royal Canadian Navy during the Second World War were different to earlier and more traditional sail-driven corvettes. The "corvette" designation was created by the French as a class of small warships; the Royal Navy borrowed the term for a period but discontinued its use in 1877. 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. The generic name "flower" was used to designate the class of these ships, which – in the Royal Navy – were named after flowering plants.

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.

Construction
Fergus was ordered 2 January 1942 as part of the 1942-43 modified Flower-class building programme. This programme was known as the Increased Endurance (IE). Many changes were made, all from lessons that had been learned in previous versions of the Flower-class. The bridge was made a full deck higher and built to naval standards instead of the more civilian-like bridges of previous versions. The platform for the 4-inch main gun was raised to minimize the amount of spray over it and to provide a better field of fire. It was also connected to the wheelhouse by a wide platform that was now the base for the Hedgehog anti-submarine mortar that this version was armed with. Along with the new Hedgehog, this version got the new QF 4-inch Mk XIX main gun, which was semi-automatic, used fixed ammunition and had the ability to elevate higher giving it an anti-aircraft ability.

Other superficial changes to this version include an upright funnel and pressurized boiler rooms which eliminated the need for hooded ventilators around the base of the funnel. This changes the silhouette of the corvette and made it more difficult for submariners to tell which way the corvette was laying.

She was laid down by Collingwood Shipyards Ltd. at Collingwood, Ontario 10 December 1943 and was launched 30 August 1944. She was commissioned into the Royal Canadian Navy 18 November 1944 at Collingwood. Due to her late arrival into the war Fergus never had a refit.

War service
After working up in Bermuda, Fergus joined the Mid-Ocean Escort Force (MOEF) as a trans-Atlantic convoy escort. She was assigned to MOEF escort group C-9 and remained with them until the end of the war. She returned to Canada in June 1945.

Post-war service
Fergus was paid off at Sydney, Nova Scotia 14 July 1945 and was placed in reserve at Sorel, Quebec. She was transferred to the War Assets Corporation later that year and sold for mercantile conversion. She reappeared as Camco II in 1945. In 1948 she was sold to the Kent Steamship Company and renamed Harcourt Kent. On 22 November 1949, Harcourt Kent wrecked off St. Shott's, Newfoundland and Labrador. She went down in a storm but all eighteen of her crew were saved.
