Design
[edit]German Type VIIC submarineswere preceded by the shorterType VIIB submarines.U-204had 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), apressure hulllength of 50.50 m (165 ft 8 in), abeamof 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and adraughtof 4.74 m (15 ft 7 in). The submarine was powered by twoGermaniawerftF46 four-stroke, six-cylindersuperchargeddiesel enginesproducing 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, twoAEGGU 460/8–27double-acting electric motorsproducing 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-204was 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/30anti-aircraft gun. The boat had acomplementof between forty-four and sixty.[3]
Service history
[edit]Part of the1st U-boat Flotilla,U-204carried out three patrols in the North Atlantic.
First patrol
[edit]U-204's first patrol began when she leftKielon 24 May 1941; she travelled through thegapbetweenGreenlandandIceland(theDenmark Strait) and sank the Icelandic fishing boatHolsteinnwith gunfire, south of Iceland on 31 May – Kell did not want news of the U-boat's presence to be broadcast. She then sankMerciereast ofNewfoundlandon 10 June. She docked atBrestin occupied France, on the 27th.
Second patrol
[edit]Nearly a month passed before the boat sortied again. On 2 August she spottedAllied convoy SL81and called for support. WhenU-401arrived the following day, they attacked together but without success.[4]On 18 Aug she joined a wolfpack searching forConvoy OG 71and shortly after 0100 the next day she struck HNoMSBathwith two torpedoes into the starboard side of her engine room and causing the destroyer to sink within three minutes at about 400 nmi (740 km; 460 mi) southwest of Ireland. Eighty-four ofBaths crew including herCOLieutenant CommanderFrederik Melsom were killed plus two others later died after rescue; the death toll was compounded by the fact that twodepth chargesexploded when the vessel went down.[5]
Third patrol and loss
[edit]Having left Brest on 20 September 1941, she sank the Spanish sailing shipAingeru Guardakoawith a single torpedo on 14 October, thinking she was a British submarine chaser. She then sankInverleeon the 19th. On the same day, she fell victim to a British anti-submarine sweep fromGibraltar.She was sunk by depth charges from the corvetteHMSMallowand the sloopHMSRochester.
Forty-six men died; there were no survivors.
Wolfpacks
