German submarine U-126 was a Type IXC U-boat of Nazi Germany's Kriegsmarine during World War II. In six patrols, she sank 25 ships for a total of and 450 tons. She was laid down at the DeSchiMAG AG Weser yard in Bremen as yard number 989 on 1 June 1940, launched on 31 December and commissioned on 22 March 1941 under Kapitänleutnant Ernst Bauer.
The submarine commenced her service with the 2nd U-boat Flotilla, an organization she would stay with, both for training and operations.
German Type IXC submarines were slightly larger than the original Type IXBs. U-126 had a displacement of when at the surface and while submerged. The U-boat had a total length of , a pressure hull length of , a beam of , a height of , and a draught of . The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of for use while submerged. She had two shafts and two propellers. The boat was capable of operating at depths of up to .
The submarine had a maximum surface speed of and a maximum submerged speed of . When submerged, the boat could operate for at ; when surfaced, she could travel at . U-126 was fitted with six torpedo tubes (four fitted at the bow and two at the stern), 22 torpedoes, one SK C/32 naval gun, 180 rounds, and a SK C/30 as well as a C/30 anti-aircraft gun. The boat had a complement of forty-eight.
U-126 opened her account by damaging the British Canadian Star about west of Lands End on 20 July 1941. She had missed with torpedoes and decided to use her guns instead, but accurate return fire from the merchantman (many merchant ships had some form of defensive armament fitted), drove her off before she could finish the job. A week later, things improved when she sank Erato on 27 July, west of northwest Spain. She used her deck gun again to sink the schooner Robert Max on 4 August east of the Azores. She sank the Yugoslavian Sud using the deck gun once more, but in conjunction with the Italian submarine Marconi on 14 August northeast of the Azores.
The boat was rewarded with two sinkings on 10 October 1941 northeast of the Cape Verde islands; Nailsea Manor was carrying HMS LCT-102 as deck cargo when she was attacked. U-126 also sank Lehigh about off Freetown, Sierra Leone, on the 19th and Peru on 13 November, southwest of Cape Palmas (Liberia).
She assisted survivors from the German commerce raider Atlantis on the 22nd.
The boat was also successful in early 1942 as part of Operation Drumbeat (Paukenschlag), the German assault on merchant shipping along the US coast. She sank many vessels, beginning with Gunny on 2 March about south of the Bermudas and finished with Olga on the 12th. One ship that did not sink was Colabee. She was attacked on the 13th about off Cape Guajaba, Cuba. The ship ran aground after being torpedoed and abandoned with her engines still running. She was salvaged, repaired and returned to service.
There was drama after the sinking of the Norwegian tanker Høegh Giant on 3 June 1942 about east of Guyana. The ship's master was questioned by the German sailors, but when he did not understand what was being said, the Germans fired over a lifeboat, wounding one man.
Other vessels were attacked in the area of the Caribbean and the West Indies, using torpedoes and the deck gun.
Patrol number five was the boat's longest â 111 days. The voyage took the submarine to west Africa. On 1 November 1942, she sank the Liberty ship George Thatcher about from the coast at Gabon. She was also successful in sinking New Toronto on the fifth from Kotonou; her cargo included 75 live cows.
One of U-126s victims on this patrol was Flora MacDonald, which was torpedoed on 30 May 1943 south of Freetown in Sierra Leone. The ship did not sink, but after being beached and the cargo salvaged, she burned for 16 days and was subsequently declared a total loss. The U-boat also hit Standella on 2 June. The submarine was attacked by an aircraft (the source does not give the type), off Freetown on 15 June. The boat was sunk by a Wellington of 127 Squadron RAF, on 3 July 1943, off Cape Ortegal, Spain. There were no survivors from the 55 man crew.
