Convoy HX 90 (1–3 December 1940) was a North Atlantic convoy of the HX series in the Second World War which ran during the Battle of the Atlantic in both world wars.
HX 90 was an eastbound convoy of 41 ships which sailed from Halifax, Nova Scotia, Canada, on 21 November 1940 bound for Liverpool, England, carrying war materials. The convoy, made up of contingents from Halifax, Sydney and Bermuda was led by convoy commodore V. P. Alleyne in Botavon. [1]
The escort for the crossing had been sparse, as was common at this stage of the campaign and the Western Approaches escort did not generally meet incoming convoys until south of Iceland, reckoned to be the limit of U-boat endurance. For Convoy HX 90, the ocean escort was the Royal Navy armed merchant cruiser HMS Laconia and she was due to rendezvous with the Western Approaches escort on 2 December. [2]
Also at sea were Convoy SC 13, to the north of Convoy HX 90, also heading east, while heading towards them was the westbound Convoy OB 251. To the south, heading to the United Kingdom from Gibraltar, was Convoy HG 47. Ranged against them was a wolfpack of seven U-boats and reinforced by three Italian submarines of BETASOM operating with them in the Atlantic Ocean. These were deployed in a patrol line at the fringe of the Western Approaches, hoping to intercept eastbound convoys before they met their escorts.
On 1 December 1940, about 500 nmi (930 km; 580 mi) south of Iceland, Convoy HX 90 was sighted by U-101 (Kapitänleutnant]] E. Mengersen which reported its position. Mengersen was ordered to shadow and report. During the day, the first Western Approaches escort, the Royal Navy destroyer HMS Viscount (Lieutenant Commander M. S. Townsend) arrived from Convoy OB 251. That evening, Mengersen was no longer able to resist attacking. He fired all twelve of his torpedoes, claiming four ships sunk and two damaged but sank Apalachee, Kavak and Lady Glanely, damaging Loch Ranza. [2]
Just after midnight on 2 December, U-47 (Gunther Prien) arrived and sank Ville D'Arlon, which had straggled from the convoy and damaged Conch. Prien attacked Dunsley, with his deck gun, but was driven off by an escort ship. Later U-95 joined, attacking the damaged Conch, which was again hit but remained afloat. U-99 (Otto Kretschmer) was en route to join the attack, but encountered the armed merchant cruiser HMS Forfar on her way to join Convoy OB 251 as ocean escort. Kretschmer hit Forfar five times with torpedoes; she sank with the loss of 172 of her crew, leaving 21 survivors. U-43 also missed the convoy, but fell in with Convoy OB 251, sinking two ships, while the Argo, having attacked Convoy HG 43, also missed Convoy HX 90, but found Convoy SC 13, attacking and sinking one ship.
On the morning of 2 December the pack was joined by U-52, which sank Tasso and Goodleigh. The convoy was joined the sloop HMS Folkestone and corvette HMS Gentian, also from Convoy OB 251. They were assisted by the Royal Canadian Navy destroyer HMCS St. Laurent, which had been travelling with Forfar but had detached to reinforce Convoy HX 90's escort. Viscount and St. Laurent attacked numerous asdic contacts, making thirteen depth-charge attacks over four hours. No U-boats were hit but all were kept submerged and silent, allowing Convoy HX 90 to escape.
Later that evening the convoy was sighted again, by U-94; she attacked during the night of 2/3 December and sank Stirlingshire and Wilhelmina. Also that night, U-99 found and sank a straggler, Victoria City, though other sources say she was sunk by U-140 and the damaged Conch, which she also sank. [3] [4] No further U-boat attacks developed for Convoy HX 90, though on 3 December W. Hendrik was bombed by German aircraft and sunk. The convoy met its local escort on 5 December and arrived in Liverpool later that day. [1]
U-Boat Command (BdU Rear Admiral Karl Dönitz) was delighted with the attack, believing his U-boats had sunk eighteen ships of over 120,000 GRT. In fact the confirmed loss to Convoy HX 90 was eleven ships of 73,495 GRT; other sources give 73,958 GRT. [3] [5] During the same period the pack had also sunk Forfar, two ships from Convoy OB 251, and another from Convoy SC 13, and had damaged an escort from Convoy HG 47. None of the attacking U-boats had been sunk or damaged. Thirty ships of Convoy HX 90 arrived safely, as did 41 ships of Convoy SC 13, the 30 ships of Convoy HG 47, and 31 ships of Convoy OB 251. The attack on Convoy HX 90 was a setback for the Allies, and one of the more serious convoy losses of the Atlantic campaign.

HMS Gladiolus was a Flower-class corvette of the Royal Navy, the first ship of her class.
This is a timeline for the Battle of the Atlantic (1939–1945) in World War II.
HMS Malcolm was one of eight Admiralty-type destroyer leaders built for the Royal Navy during World War I. She was the first of only two Royal Navy ships to carry the name Malcolm, although HMS Valkyrie was originally planned to bear the name. She was one of two Admiralty-type leaders to miss the First World War but saw service in, and survived, the Second World War. Her pennant number was changed from D19 to I19 in May 1940. She was broken up in 1945.
SC 7 was the code name for a large Allied convoy in the Second World War comprising 35 merchant ships and six escorts, which sailed eastbound from Sydney, Nova Scotia, for Liverpool and other British ports on 5 October 1940. While crossing the Atlantic, the convoy was attacked by one of the first U-boat wolfpacks. The escorts were overwhelmed, twenty of the 35 cargo vessels were sunk and two were damaged, with 141 lives lost. The disaster demonstrated the potency of wolfpacks and the inadequacy of British anti-submarine operations.
HMS Arbutus was a Flower-class corvette of the Royal Navy, which was active during the Second World War. She was a successful escort vessel, and took part in the destruction of two U-boats during the Battle of the Atlantic. Arbutus was torpedoed by a U-boat and sunk in the North Atlantic in February 1942 while aiding a convoy that was under attack.
German submarine U-99 was a Type VIIB U-boat of Nazi Germany's Kriegsmarine during World War II. She was laid down on 31 March 1939 at the Friedrich Krupp Germaniawerft in Kiel as yard number 593. She was launched on 12 March 1940 under the command of Korvettenkapitän Otto Kretschmer and was assigned to the 7th U-boat Flotilla based in Kiel and later in St Nazaire.
German submarine U-96 was a Type VIIC U-boat of the German Navy (Kriegsmarine) during World War II. It was made famous after the war in Lothar-Günther Buchheim's 1973 bestselling novel Das Boot and the 1981 Oscar-nominated film adaptation of the same name, both based on his experience on the submarine as a war correspondent in 1941.
HX 79 was an Allied convoy in the North Atlantic of the HX series, which sailed east from Halifax, Nova Scotia. The convoy took place during the Battle of the Atlantic in the Second World War. One ship dropped out and returned to port, leaving 49 to cross the Atlantic for Liverpool. Two armed merchant cruisers and a submarine escorted the convoy to protect it from German commerce raiders.
OB 293 was a North Atlantic convoy which ran during the battle of the Atlantic in World War II. It was notable for seeing the loss to the Kriegsmarine (KM) of U-47, with her commander KL Günther Prien, the person responsible for the sinking of HMS Royal Oak two years previously.
HX 112 was a North Atlantic convoy of the HX series which ran during the battle of the Atlantic in the Second World War. It saw the loss of U-boats commanded by two of the Kriegsmarine's most celebrated commanders and propaganda heroes: U-99 under Otto Kretschmer (POW), and U-100 under Joachim Schepke (KIA).
Convoy SC 42 was the 42nd of the numbered series of World War II Slow Convoys of merchant ships from Sydney, Cape Breton Island to Liverpool. SC 42 was attacked over a three night period in September 1941, losing 16 ships sunk and 4 damaged. This was the worst Allied loss following the attack on convoy SC 7 the previous year. Two attacking U-boats were destroyed.
German submarine U-101 was a Type VIIB U-boat of Nazi Germany's Kriegsmarine during World War II. She had a highly successful career.
HX 228 was a North Atlantic convoy of the HX series which ran during the Battle of the Atlantic in World War II. It was one of a series of four convoy battles that occurred during the crisis month of March 1943 and is notable for the loss of the Escort Group leader Commander AA "Harry" Tait.
HMS Viscount was a V-class destroyer of the British Royal Navy that saw service in the final months of World War I and in World War II.
Convoy HX 126 was the 126th of the numbered series of World War II HX convoys of merchant ships from HalifaX to Liverpool.

It was the 65th of the numbered series of merchant convoys run by the Allies from Halifax to Liverpool. The convoy was attacked by German U-boats and aircraft, losing eight of its 51 ships sunk and a further three damaged. One U-boat was damaged.
Convoy HG 73 was a trade convoy of merchant ships during the Second World War. It was the 73rd of the numbered HG convoys Homeward bound to the British Isles from Gibraltar. The convoy departed Gibraltar on 17 September 1941 and was spotted by a German reconnaissance aircraft on 18 September. The convoywas attacked over the next ten days. Nine ships were sunk from the convoy before the submarines exhausted their torpedo inventory on 28 September. The convoy reached Liverpool on 1 October.
Convoy HX 47 was a North Atlantic convoy of the HX series which ran during the battle of the Atlantic in World War II. It was the 47th of the numbered series of merchant convoys run by the Allies from Halifax to Liverpool. The convoy was attacked by German U-boats and lost three of its 58 ships.
HMS Hibiscus was a Flower-class corvette, built for the Royal Navy during the Second World War, and was in service in the Battle of the Atlantic. In 1942 she was transferred to the United States Navy as part of the Reverse Lend-Lease arrangement and renamed USS Spry, one of the Temptress-class gunboats. With the end of hostilities she was returned to the Royal Navy and sold into mercantile service.
HMS Periwinkle was a Flower-class corvette, built for the Royal Navy during the Second World War, and was in service in the Battle of the Atlantic.
