HMCS Thorlock was a modified Flower-class corvette that served in 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 Thorold, Ontario. Her name was changed due to local preference.[2] After the war she was sold to the Chilean Navy.

Flower-class corvette

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.

Royal Canadian Navy

Royal Canadian Navy

The Royal Canadian Navy is the naval force of Canada. The RCN is one of three environmental commands within the Canadian Armed Forces. As of 2021, the RCN operates 12 frigates, four attack submarines, 12 coastal defence vessels, eight patrol class training vessels, two offshore patrol vessels, and several auxiliary vessels. The RCN consists of 8,570 Regular Force and 4,111 Primary Reserve sailors, supported by 3,800 civilians. Vice-Admiral Angus Topshee is the current commander of the Royal Canadian Navy and chief of the Naval Staff.

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 Thorlock 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 as a class 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]

Winston Churchill

Winston Churchill

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 and career

Thorlock was ordered in June 1942 as part of the 1943–44 Increased Endurance Flower-class building program, which followed the main layout of the 1942–43 program. The only significant difference is that the majority of the 43–44 program replaced the 2-pounder Mk.VIII single "pom-pom" anti-aircraft gun with 2 twin 20-mm and 2 single 20-mm anti-aircraft guns.[9] Thorlock was laid down by Midland Shipyards Ltd. at Midland, Ontario 25 September 1943 and launched 15 May 1944.[10][11] She was commissioned into the RCN 13 November 1944 at Midland.[2]

After working up in Bermuda, Thorlock was assigned to the Mid-Ocean Escort Force. She was allocated to escort group C-9 as a trans-Atlantic convoy escort. She escorted her first convoy at the end of February 1945. She spent the remainder of the war as a convoy escort. On 12 May 1945 while escorting ON 300 she was diverted along with HMCS Victoriaville to accept the surrender of U-190 and escort her to Bay Bulls, Newfoundland and Labrador.[2]

Thorlock was paid off 15 July 1945 at Sorel, Quebec and placed in reserve. She was transferred to the War Assets Corporation and sold to the Chilean Navy in 1946.[2]

Chilean Navy

She arrived in Chile 12 April 1946 and was renamed Papudo. She served in the Chilean Navy until 6 April 1945 when she was struck.[12] She was sold for scrap and broken up in 1967.[10][11]

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.

ON convoys

The ON convoys were a series of North Atlantic trade convoys running Outbound from the British Isles to North America during the Battle of the Atlantic.

She was named for Victoriaville, Quebec. After the war she was converted to a Prestonian-class frigate in 1959. In 1966 she was converted to a diving tender and renamed Granby, serving as such until 1973 when she was decommissioned for the final time.

Ship breaking

Ship breaking

Ship-breaking is a type of ship disposal involving the breaking up of ships for either a source of parts, which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking is sustainable, there are concerns about the use by poorer countries without stringent environmental legislation. It is also labour-intensive, and considered one of the world's most dangerous industries.
