German submarineU-596 was aType VIICU-boat built forNazi Germany'sKriegsmarine for service duringWorld War II.She waslaid down on 4 January 1941 byBlohm & Voss inHamburg as yard number 572,launched on 17 September 1941 andcommissioned on 13 November underKapitänleutnantGunter Jahn. He was replaced on 28 July 1943 byOberleutnant zur See Victor-Whilhelm Nonn who was superseded byOblt.z.S. Hans Kolbus in July 1944.
The boat's service began on 13 November 1941 with training as part of the8th U-boat Flotilla. She was transferred to the3rd flotilla on 1 July 1942 and moved on to the29th flotilla on 19 November.
German Type VIIC submarines were preceded by the shorterType VIIB submarines.U-596 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), apressure hull length of 50.50 m (165 ft 8 in), abeam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and adraught of 4.74 m (15 ft 7 in). The submarine was powered by twoGermaniawerft F46 four-stroke, six-cylindersuperchargeddiesel 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, twoBrown, Boveri & Cie GG UB 720/8double-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-596 was fitted with five 53.3 cm (21 in)torpedo tubes (four fitted at the bow and one at the stern), fourteentorpedoes, one8.8 cm (3.46 in) SK C/35 naval gun, 220 rounds, and a2 cm (0.79 in) C/30 anti-aircraft gun. The boat had acomplement of between forty-four and sixty.[2]
In twelve patrols, she sank twelve ships, including one warship for a total of 41,411 GRT.
Her initial sortie fromKiel was cut short by a battery explosion on 28 June 1942. She was obliged to put intoBergen in Norway.
Her first patrol saw her depart Bergen on 8 August 1942, cross theNorth Sea and move through thegap betweenIceland and theFaroe Islands into the Atlantic. There she sank theSuecia with a torpedo on 16 August, having first checked the ships' papers. She also sank theEmpire Hartebeeste on 20 September, but was attacked byHNoMS Potentilla andHMS Viscount on 24 August. No damage was sustained.U-596 lost a man overboard on 30 August in mid-Atlantic. The boat then docked atSt. Nazaire in occupied France on 3 October.
Her next foray from St. Nazaire took the U-boat as part of group 'Delphin' toLa Spezia in northern Italy. Her route involved passing the heavily defendedStrait of Gibraltar, which she successfully accomplished in the darkness during the period of the new moon from 8–10 November 1942.[3]
U-596's third patrol took her past theBalearic Islands to the Algerian coast nearOran. It was unsuccessful.
Her fourth foray yielded some reward. BetweenAlgiers and Oran, she damagedFort Norman andEmpire Standard, both on 9 March 1943.
Her fifth outing, in the same area as her third and fourth patrols, was rewarded with the sinking of theFort a la Corne west of Algiers on 30 March 1943.
Her home port was moved from La Spezia toPola in Croatia; she sailed from there on her sixth patrol, but it was uneventful.
Patrol number seven was marked by the sinking of several Egyptian, a Palestinian and British-registered sailing ships off theLebanon coast with herdeck gun in August and September 1943.
During her eighth patrol, she sankMarit off the Libyan coast on 4 October, but was attacked by the British corvetteHMS Gloxina. Although slightly damaged, the U-boat escaped.
U-596 departed Pola on 30 November but it was not until many days later that she sank the Troop TransportCap Padaran offCape Spartivento in Italy on 9 December. She returned to Pola on 28 December 1943.
Another unsuccessful patrol passed between 12 February and 11 March 1944.
The boat barely left theAdriatic for patrol number eleven.
What turned out to be the last complete patrol by a U-boat in theMediterranean[4] began withU-596's departure from Pola on 29 July 1944. Her route was to theGulf of Sirte on the Libyan coast. Her arrival atSalamis in Greece was followed by theUSAAF (United States Army Air Forces) bombing the port on 29 September (USAAF records say the 25th). The boat was sufficiently damaged that the crew was forced to abandon her and join the general retreat throughAthens.[5]
The submarine was scuttled on 30 September 1944 inSkaramanga Bay, near Salamis in position37°59′N23°34′E / 37.983°N 23.567°E /37.983; 23.567. One person died; the number of survivors is unknown.
