Armament

HMCS Amherst was a Flower-class corvette of the Royal Canadian Navy. She served primarily in the Battle of the Atlantic on convoy protection duty during the Second World War. She was named for Amherst, Nova Scotia. The ship was laid down at Saint John Dry Dock and Shipbuilding Co. Ltd. in Saint John, New Brunswick, on 23 May 1940 and launched on 3 December later that year. Amherst was commissioned on 5 August 1941 and served in the Battle of the Atlantic and Battle of the St. Lawrence, earning battle honours for both actions. After the war, the ship was decommissioned and sold to Venezuelan Navy in 1945 and renamed Carabobo. However, while en route to Venezuela, the ship was wrecked in the Gulf of St. Lawrence that same year.

Saint John is a seaport city of the Atlantic Ocean located on the Bay of Fundy in the province of New Brunswick, Canada. Saint John is the oldest incorporated city in Canada, established by royal charter on May 18, 1785, during the reign of King George III. The port is Canada's third-largest port by tonnage with a cargo base that includes dry and liquid bulk, break bulk, containers, and cruise. The city was the most populous in New Brunswick until the 2016 census, when it was overtaken by Moncton. It is currently the second-largest city in the province, with a population of 69,895 over an area of 315.59 km2 (121.85 sq mi).

Ceremonial ship launching

Ceremonial ship launching

Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself.

Battle of the St. Lawrence

Battle of the St. Lawrence

The Battle of the St. Lawrence involved marine and anti-submarine actions throughout the lower St. Lawrence River and the entire Gulf of Saint Lawrence, Strait of Belle Isle, Anticosti Island and Cabot Strait from May–October 1942, September 1943, and again in October–November 1944. During this time, German U-boats sank over 20 merchant ships and four Canadian warships. There were several near-shore actions involving the drop of German spies, or the attempted pickup of escaping prisoners of war. Despite the 23 ships lost, this battle marked a strategic victory for Canadian forces as ultimately they managed to disrupt U-boat activity, protect Canadian and Allied convoys, and intercept all attempted shore operations. This marked the first time that a foreign power had inflicted casualties in Canadian inland waters since the US incursions in the War of 1812.

Battle honour

Battle honour

A battle honour is an award of a right by a government or sovereign to a military unit to emblazon the name of a battle or operation on its flags ("colours"), uniforms or other accessories where ornamentation is possible.

Gulf of St. Lawrence

Gulf of St. Lawrence

The Gulf of St. Lawrence is the outlet of the North American Great Lakes via the St. Lawrence River into the Atlantic Ocean. The gulf is a semi-enclosed sea, covering an area of about 226,000 square kilometres (87,000 sq mi) and containing about 34,500 cubic kilometres (8,300 cu mi) of water, at an average depth of 152 metres (500 ft).

Design and description

Flower-class corvettes like Amherst serving with the Royal Canadian Navy (RCN) during the Second World War were different from earlier and more traditional sail-driven corvettes.[1][2] The Flower-class corvettes originated from a need that arose in 1938 to expand the Royal Navy following the Munich Crisis.[3] A design request went out for a small escort for coastal convoys.[4] Based on a traditional whaler-type design, the initial Canadian ships of the Flower class had a standard displacement of 950 long tons (970 t). They were 205 feet 1 inch (62.51 m) long overall with a beam of 33 feet 1 inch (10.08 m) and a maximum draught of 13 feet 5 inches (4.09 m). The initial 1939–1940 corvettes were powered by a four-cylinder vertical triple expansion engine powered by steam from two Scotch boilers turning one three-bladed propeller rated at 2,800 indicated horsepower (2,100 kW). The Scotch boilers were replaced with water-tube boilers in later 1939–1940 and 1940–1941 Programme ships. The corvettes had a maximum speed of 16 knots (30 km/h; 18 mph). This gave them a range of 3,450 nautical miles (6,390 km; 3,970 mi) at 12 knots (22 km/h; 14 mph).[5] The vessels were extremely wet.[6]

The Canadian Flower-class vessels were initially armed with a Mk IX BL 4-inch (102 mm) gun forward on a CP 1 mounting and carried 100 rounds per gun. The corvettes were also armed with a QF Vickers 2-pounder (40 mm, 1.6 in) gun on a bandstand aft, two single-mounted .303 Vickers machine guns or Browning 0.5-calibre machine guns for anti-aircraft defence and two twin-mounted .303 Lewis machine guns, usually sited on bridge wings.[3][5][7] For anti-submarine warfare, they mounted two depth charge throwers and initially carried 25 depth charges. The corvettes were designed with a Type 123 ASDIC sonar set installed. The Flower-class ships had a complement of 47 officers and ratings.[3] The Royal Canadian Navy initially ordered 54 corvettes in 1940 and these were fitted with Mark II Oropesa minesweeping gear used for destroying contact mines.[8] Part of the depth charge rails were made portable so the minesweeping gear could be utilised.[9]

Modifications

In Canadian service the vessels were altered due to experience with the design's deficiencies. The galley was moved further back in the ship and the mess and sleeping quarters combined. A direction-finding set was installed and enlarged bilge keels were installed to reduce rolling.[10] After the first 35–40 corvettes had been constructed, the foremast was shifted aft of the bridge and the mainmast was eliminated. Corvettes were first fitted with basic SW-1 and SW-2 CQ surface warning radar, notable for their fishbone-like antenna and reputation for failure in poor weather or in the dark. The compass house was moved further aft and the open-type bridge was situated in front of it. The ASDIC hut was moved in front and to a lower position on the bridge. The improved Type 271 radar was placed aft, with some units receiving Type 291 radar for air search. The minesweeping gear, a feature of the first 54 corvettes, was removed.[11] Most Canadian Flower-class corvettes had their forecastles extended which improved crew accommodation and seakeeping. Furthermore, the sheer and flare of the bow was increased, which led to an enlarged bridge. This allowed for the installation of Oerlikon 20 mm (0.8 in) cannon, replacing the Browning and Vickers machine guns.[12] Some of the corvettes were rearmed with Hedgehog anti-submarine mortars.[13] The complements of the ships grew throughout the war rising from the initial 47 to as many as 104.[12]

Royal Navy

Royal Navy

The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service.

Convoy

Convoy

A convoy is a group of vehicles, typically motor vehicles or ships, traveling together for mutual support and protection. Often, a convoy is organized with armed defensive support and can help maintain cohesion within a unit. It may also be used in a non-military sense, for example when driving through remote areas.

Displacement (ship)

Displacement (ship)

The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used.

Long ton

Long ton

The long ton, also known as the imperial ton or displacement ton, is the name for the unit called the "ton" in the avoirdupois system of weights or Imperial system of measurements. It was standardised in the 13th century. It is used in the United Kingdom and several other Commonwealth of Nations countries alongside the mass-based metric tonne defined in 1799, as well as in the United States for bulk commodities.

Tonne

Tonne

The tonne is a unit of mass equal to 1000 kilograms. It is a non-SI unit accepted for use with SI. It is also referred to as a metric ton to distinguish it from the non-metric units of the short ton, and the long ton. It is equivalent to approximately 2204.6 pounds, 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram, a less common way to express the same mass.

Length overall

Length overall

Length overall is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth.

Beam (nautical)

Beam (nautical)

The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water.

Draft (hull)

Draft (hull)

The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water.

Propeller

Propeller

A propeller is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft with an approximately horizontal axis.

Construction and career

Ordered from Saint John Dry Dock and Shipbuilding Co. Ltd. in Saint John, New Brunswick as part of the 1939–1940 Flower-class building programme, Amherst was laid down on 23 May 1940 and launched on 3 December later that year. She was commissioned on 5 August 1941 at Saint John and then sent to Halifax, Nova Scotia to undergo work ups.[14]

War service

After her commissioning Amherst was sent on convoy escort duty from 22 August 1941 until her first refit in 1943.[14] The ship was assigned to Newfoundland Force[14] and on 11 October 1941, the escort for convoy SC 49 was taken over by the Canadian escort group 4.1.16, of which Amherst was a member. During their escort, the convoy was rerouted to the north of convoy SC 48 and their ongoing battle. On 22 October, escort of the convoy was handed over to the British escort group EG 4 at the Mid-Ocean Meeting Point (MOMP).[15] On 6 November, Amherst's escort group took over the escort of convoy ONS 32 at the MOMP, first rerouting to the south to avoid the German U-boats before arriving without incident. This was followed by four more uneventful convoy escort missions, SC 56, ONS 44, SC 63 and ONS 58 taking the ship into 1942.[16]

In August 1942, Amherst was made a member of the Mid-Ocean Escort Force (MOEF) escort group C-4. The unit was escorting convoy ON 127 when it is sighted by a U-boat on 9 September. The wolfpack "Vorwärts" moved to intercept and engaged the convoy on 10 September. Hampered by faulty radar, the escort is overwhelmed, losing the destroyer HMCS Ottawa during the battle. The battle lasts until 14 September, out of the 32 freighters in the convoy, 10 were sunk, plus a trawler that was near the convoy, comprising 79,263 gross register tons (GRT).[17] During the battle, Amherst was fired upon by the German submarine U-92 but all of the torpedoes missed while recovering the survivors of SS Hindanger.[18] Amherst and sister ship Sherbrooke detached from the convoy on 15 September, escorting four merchant vessels that had been damaged in the battle to St. John's, Newfoundland.[19] Amherst and C-4 then escorted convoy SC 101 at the end of the month, losing only one ship that had straggled behind the main body of the convoy to the U-boats.[20]

On 16 October 1942, C-4 was escorting convoy ON 137 which was spotted by German forces. However, the convoy evaded the wolfpacks "Panther" and "Wotan" without loss.[21] At the end of October, C-4 was deployed on escort duty, this time with convoy SC 107, consisting of 42 ships.[22] However, Amherst had recently had a change in command, and two of the group were only on passage to the United Kingdom. First contact between the opposing forces took place on 30 October, but was lost until 2 November. The wolfpack "Velichen" was placed across SC 107's path.[23] Amherst engaged several U-boats. During his first encounter the commanding officer, Lieutenant Louis Audette, went up to the crowsnest to direct fire down on the surfaced U-boat. The next night during her attempt to sink another submarine her ASDIC lost power and she lost contact. During the same convoy, a member of the crew earned a British Empire Medal for helping save three stranded crew from a burning vessel.[24] However, the convoy lost 15 ships, comprising 82,777 GRT.[22]

In January 1943, C-4 was deployed to escort convoy HX 224, which was discovered by Axis forces on 1 February. The convoy was attacked and three merchant ships were sunk comprising 24,823 GRT.[25] Later that month C-4 was sent to Londonderry for training, before sailing on 2 March to escort eight troopships sailing as convoy KMF 10B to Algiers. They passed through the Strait of Gibraltar uneventfully, but came under attack by German Focke-Wulf Fw 200 Condor aircraft, damaging one of the troopships. The rest of the convoy was uneventful, arriving at Algiers on 17 March.[26] C-4 sailed for the United Kingdom escorting the return convoy MKF 10B uneventfully. In early April C-4 escorted convoy ON 177, making the trip safely, after being rerouted to avoid German wolfpacks.[27] Amherst was re-assigned to MOEF group C2 and the unit escorted ON 149 in late April. Though the German forces made contact during the transit, the convoy arrived safely.[28]

Amherst underwent a major refit at Charlottetown, Prince Edward Island, getting her forecastle extended among other changes to the ship from May to November 1943. After more workups at Pictou, Nova Scotia the corvette returned to convoy escort duty in the Atlantic until her second refit in September 1944. After work was completed Amherst was worked up in Bermuda. Amherst was assigned to Halifax Force in January 1945, tasked with local defence. In March the corvette joined the escort group C-7 for one more round trip to the United Kingdom before the end of the war in the Atlantic.[14] Amherst was awarded the battle honours "Atlantic 1941–45"[29] and "Gulf of St. Lawrence 1944"[30] for service during the Second World War.

Fate

Amherst was paid off from service on 11 July 1945 at Sydney, Nova Scotia. The corvette was then placed in reserve at Sorel, Quebec. The ship was one of seven corvettes disposed of by sale on 17 October to the Venezuelan Navy and was renamed Carobobo. However, while departing Canadian waters for Venezuela, the ship was wrecked in the Gulf of St. Lawrence.[14][31][a]

Newfoundland Escort Force

The Newfoundland Escort Force (NEF) was a Second World War naval command created on 20 May 1941 as part of the Allied convoy system in the Battle of the Atlantic. Created in response to the movement of German U-boats into the western Atlantic Ocean, the Newfoundland Escort Force (NEF) was instituted to cover the convoy escort gap that existed between the local convoy escort in Canada and the United Kingdom. The Royal Canadian Navy provided the majority of naval vessels to the NEF along with its commander Commodore Leonard W. Murray, with units from the British, Norwegian, Polish, French and Dutch navies also assigned. The NEF was reconstituted as part of the Mid-Ocean Escort Force in 1942.

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.

Convoy ON 127

Convoy ON 127

Convoy ON 127 was a trade convoy of merchant ships during the second World War. It was the 127th of the numbered series of ON convoys Outbound from the British Isles to North America and the only North Atlantic trade convoy of 1942 or 1943 where all U-boats deployed against the convoy launched torpedoes. The ships departed Liverpool on 4 September 1942 and were met at noon on 5 September by the Royal Canadian Navy Mid-Ocean Escort Force Group C-4 consisting of the Canadian River-class destroyer Ottawa and the Town-class destroyer St. Croix with the Flower-class corvettes Amherst, Arvida, Sherbrooke, and Celandine. St. Croix's commanding officer, acting Lieutenant Commander A. H. "Dobby" Dobson RCNR, was the senior officer of the escort group. The Canadian ships carried type 286 meter-wavelength radar but none of their sets were operational. Celandine carried Type 271 centimeter-wavelength radar. None of the ships carried HF/DF high-frequency direction finding sets.

Destroyer

Destroyer

In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy, or battle group and defend them against powerful short-range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish Navy as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War.

Gross register tonnage

Gross register tonnage

Gross register tonnage or gross registered tonnage, is a ship's total internal volume expressed in "register tons", each of which is equal to 100 cubic feet (2.83 m3). Replaced by Gross Tonnage (GT), gross register tonnage uses the total permanently enclosed capacity of the vessel as its basis for volume. Typically this is used for dockage fees, canal transit fees, and similar purposes where it is appropriate to charge based on the size of the entire vessel. Internationally, GRT may be abbreviated as BRT for the German "Bruttoregistertonne".
