German submarine U-379

German submarine U-379 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. She was laid down on 27 May 1940 by Howaldtswerke, Kiel as yard number 10, launched on 15 October 1941 and commissioned on 29 November 1941 under Kapitänleutnant Paul-Hugo Kettner.

Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-379 had a displacement of 769 t when at the surface and 871 t while submerged. She had a total length of 67.10 m, a pressure hull length of 50.50 m, a beam of 6.20 m, a height of 9.60 m, and a draught of 4.74 m. The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2800 to 3200 PS for use while surfaced, two Garbe, Lahmeyer & Co. RP 137/c double-acting electric motors producing a total of 750 PS for use while submerged. She had two shafts and two 1.23 m propellers. The boat was capable of operating at depths of up to 230 m.

The submarine had a maximum surface speed of 17.7 kn and a maximum submerged speed of 7.6 kn. When submerged, the boat could operate for 80 nmi at 4 kn; when surfaced, she could travel 8500 nmi at 10 kn. U-379 was fitted with five 53.3 cm torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm SK C/35 naval gun, 220 rounds, and a 2 cm C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.

Service history
The boat's career began with training at 8th U-boat Flotilla on 29 November 1941, followed by active service on 1 July 1942 as part of the 1st Flotilla for the remainder of her short career.

In one patrol she sank two merchant ships, for a total of.

Convoy SC 94
On the calm and sunny afternoon of 8 August 1942, U-379 attacked and sunk two merchant ships of Convoy SC 94, which was Eastbound from Nova Scotia to Liverpool, first US freighter Kaimoku, swiftly followed by the British freighter Anneberg.

However, later the same day, U-379 was spotted on the surface together with GS U-176 exchanging information. RN corvette HMS Dianthus (K95) gave chase firing her guns at the surfaced U-boat as she desperately dived. HMCS Chilliwack (K131) joined HMS Dianthus making a thorough ASDIC sweep but found nothing, so HMCS Chilliwack rejoined the convoy.

HMS Dianthus remained in the area and tried one last sweep and spotted U-379 again on the surface in the darkness attempting to slink away. She fired off a spread of depth charges forcing the now submerged U-boat to the surface. Dianthus opened up with all her guns and prepared to ram, catching the U-boat a glancing blow forward of the conning tower. U-379 finally sank after being rammed four times.

Wolfpacks
U-379 took part in two wolfpacks, namely:
 * Wolf (13 July – 1 August 1942)
 * Steinbrinck (3 – 8 August 1942)

Fate
U-379 was sunk on 8 August 1942 in the North Atlantic southeast of Cape Farewell, Greenland, in position 57.18333°N, -30.95°W, by ramming and depth charges from the Royal Navy corvette HMS Dianthus (K95). There were 40 dead and 5 survivors.
