German submarine U-264 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 21 June 1941 at the Bremer-Vulkan-Vegesacker Werft (yard) in Bremen as yard number 29. She was launched on 2 April 1942 and commissioned on 22 May under the command of Oberleutnant zur See Hartwig Looks.^[1]

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-264 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.^[3] She had a total length of 67.10 m (220 ft 2 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two AEG GU 460/8–27 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. She had two shafts and two 1.23 m (4 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).^[3]

The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a maximum submerged speed of 7.6 knots (14.1 km/h; 8.7 mph).^[3] When submerged, the boat could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph). U-264 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm (3.46 in) SK C/35 naval gun, 220 rounds, and two twin 2 cm (0.79 in) C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.^[3]

Service history

After training with the 8th U-boat Flotilla, the boat became operational on 1 November 1942 when she was transferred to the 6th flotilla.

First and second patrols

U-264's first patrol began when she departed Kiel on 3 November 1942. She entered the Atlantic Ocean after negotiating the gap between the Faroe and the Shetland Islands. On 17 November, she sank the Mount Taurus. She was attacked by a Norwegian corvette, HNoMS Potentilla, on the 20th. No damage was sustained. She entered St. Nazaire in occupied France, on 4 December.

The boat's second sortie was relatively uneventful.

Third patrol

On 26 February 1943 just off Cape Finisterre she fired a salvo of four torpedoes at HMS Sussex but all four missed; Sussex had just attacked and sunk the German Tanker Hohenfriedburg.^[4] On 17 April 1943, she was in the process of attacking Convoy HX 233 when she was attacked by the escorts. The boat was badly damaged, but was repaired by the crew and the patrol continued. She then sank the Harperley and the West Maximus500 nautical miles (930 km; 580 mi) south of Cape Farewell (Greenland) on 5 May. She docked at Lorient, on the French Atlantic coast, on 1 June.

There then followed a pair of short 'hops' between Lorient and St. Nazaire in August and September 1943.

Fourth patrol

While on her fourth patrol, U-264 and two other U-boats were re-fuelling from the supply submarine U-460 on 4 October 1943 when they were surprised by aircraft from the American carrier USS Card. The more nimble Type VIIs escaped, but the 'milch cow' was sunk by the Avengers. U-264 did not remain unscathed for long; later that day she was attacked, the damage inflicted forced a return to base.

Fifth patrol and loss

For her final sortie, she was again in the North Atlantic. She was damaged by depth charges dropped by the British sloops HMS Woodpecker and HMS Starling and forced to the surface on 19 February 1944 in position 48°31′N22°05′W / 48.517°N 22.083°W / 48.517; -22.083 . Starling opened fire on the submarine, scoring several hits, as the crew abandoned the boat and it then sank.

The entire crew of 52 officers and men were taken prisoner.

Wolfpacks

U-264 took part in eleven wolfpacks, namely:

Kreuzotter (15 – 20 November 1942)
Delphin (23 January – 9 February 1943)
Rochen (9 – 20 February 1943)
Without name (15 – 18 April 1943)
Specht (19 April – 4 May 1943)
Fink (4 – 6 May 1943)
Naab (12 – 15 May 1943)
Donau 2 (15 – 19 May 1943)
Mosel (19 – 23 May 1943)
Igel 2 (15 – 17 February 1944)
Hai 1 (17 – 19 February 1944)
