German submarine U-591 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. She was laid down on 30 October 1940 by Blohm & Voss, Hamburg as yard number 567, launched on 20 August 1941 and commissioned on 9 October 1941 under Kapitänleutnant Hans-Jürgen Zetzsche.
Design
[edit]German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-591 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[2] 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 Brown, Boveri & Cie GG UB 720/8 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).[2]
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).[2] 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-591 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 a 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.[2]
Service history
[edit]The boat's service began on 9 October 1941 with training, followed by active service as part of the 6th U-boat Flotilla. She was transferred to the 11th Flotilla on 1 July 1942 for active service in the North Atlantic operating out of Bergen. The following year, on 1 June 1943, she transferred to 9th Flotilla operating of Brest, France.
In 8 patrols she sank four merchant ships, for a total of 19,932 gross register tons (GRT), plus one merchant ship damaged.
Convoy ONS 154
[edit]The first victim of Convoy ONS 154 was the 5,701-GRT Norwegian freighter Norse King, the second in column eleven, on 28 December 1942. U-591 torpedo hit her at 20:04. Badly damaged, Norse King attempted to limp to the Azores but was found by U-435 and sent to the bottom.
U-591’s second success was the badly damaged and abandoned 4,871-GRT United Africa Company freighter Zarian with a single torpedo, although she missed the Baron Cochrane
Convoy SC 121
[edit]Having recently returned to sea after a long recovery from gunshot wounds, Hans-Jürgen Zetzsche was on target with Convoy SC 121 when he sighted the Empire Impala, hove-to picking up survivors from the torpedoed Egyptian, on 7 March 1943. Of the combined crew of 80 men, from both Egyptian and Empire Impala, only 3 survived.
Fate
[edit]U-591 was sunk on 30 July 1943 in the South Atlantic near Pernambuco in position 08°36′S 34°34′W / 8.600°S 34.567°W; depth charged by a US Lockheed Ventura aircraft of VB-127. There were 19 dead and 28 survivors.
Wolfpacks
[edit]U-591 took part in nine wolfpacks, namely:
- Schlei (21 January – 12 February 1942)
- Bums (6 – 10 April 1942)
- Greif (14 – 29 May 1942)
- Nebelkönig (27 July – 13 August 1942)
- Ungestüm (11 – 30 December 1942)
- Sturmbock (21 – 26 February 1943)
- Wildfang (26 February – 5 March 1943)
- Westmark (6 – 11 March 1943)
- Seewolf (21 – 30 March 1943)
