German submarine U-87 was a

Joachim Berger. U-87 trained with 6th U-boat Flotilla

until 1 December 1941, when she was put on front-line service.

U-87 sank five ships in her one-year career; she was a member of five wolfpacks.

She was sunk off the coast of Leixões in Portugal during her fifth combat patrol, in March 1943, by warships of the Canadian Navy.^[1]

Design

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 460/8-276 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 17.9 knots (33.2 km/h; 20.6 mph) and a maximum submerged speed of 8 knots (15 km/h; 9.2 mph).

anti-aircraft gun The boat had a complement of between forty-four and sixty.^[3]

Service history

First patrol

U-87 sailed from Kiel on 24 December 1941, and headed out into the Atlantic via the North Sea. On the evening of 31 December, the boat encountered the Cardita, which was straggling behind convoy HX 166, bound for

Shellhaven. A single torpedo hit the vessel, resulting in the deaths of twenty-seven crew members. The thirty-three survivors were picked up on 3 January by HMS Onslow and HMS Sabre

.

Meanwhile, U-87 completed her voyage around the British isles and crossed the Atlantic, where on 17 January, the submersible struck again. The Norwegian vessel Nyholt was nearing the completion of convoy ON-52's journey from Reykjavík to New York. While passing the Newfoundland coast, Nyholt was struck amidships after she left the safety of her convoy, which had been harassed by U-86 and U-553 over the previous two days. Attempting to divert further from their course to reach Newfoundland, U-87 reacted poorly to the movement and four subsequent torpedoes missed. Another two hits failed to sink the tanker, and U-87 was forced to surface for its crew to fire the deck gun as the ship's crew took to their lifeboats, not to be rescued for another nine days.

U-87 was damaged by gunfire from the tanker, and re-crossed the Atlantic, to arrive at La Pallice in France on 30 January 1942 after 38 days at sea.^[4]

Second patrol

U-87 sailed on 22 February 1942 for a second trip to the east coast of North America, but was held in the

St. Nazaire on 27 March.^[5]

Third patrol

U-87 sailed on 19 May 1942 and laid a field of 15

troy ounces of platinum.^[6] On 22 June U-87 was damaged off Halifax Harbour, by depth charges from Lockheed Hudson aircraft of 11 Squadron Royal Canadian Air Force. The boat was unable to continue the patrol and returned to port on 8 July.^[7]

Fourth patrol

U-87 sailed on 31 August 1942 to patrol off Freetown, where she sank the 7,392 GRT British freighter Agapenor before docking in Brest on 20 November 1942.^[8]

Fifth patrol and loss

U-87 sailed on 9 January 1943, and was sunk by depth charges from Canadian warships, the corvette HMCS Shediac and the destroyer HMCS St. Croix during an unsuccessful 4 March attack on convoy KMS 10G.^[1] On this last patrol she had 50 crewmen on board, none of whom survived the sinking.

Wolfpacks

U-87 took part in five wolfpacks, namely:

Zieten (6 – 17 January 1942)
Westwall (2 – 12 March 1942)
Iltis (6 – 23 September 1942)
Delphin II (20 January – 9 February 1943)
Rochen (9 – 26 February 1943)
