Design
The submarine had a maximum surface speed of 18.3 knots (33.9 km/h; 21.1 mph) and a maximum submerged speed of 7.3 knots (13.5 km/h; 8.4 mph).
Service history
First patrol
U-504's first war patrol took her from Kiel in Germany, to her home port of Lorient, in occupied France, between 6 and 20 January 1942 without incident.[4]
Second patrol
On 25 January 1942 U-504 sailed from Lorient, and headed across the Atlantic to the Florida coast.
U-504 struck again on 26 February sinking the unescorted Dutch 8,245 GRT tanker Mamura about 230 nautical miles (430 km; 260 mi) off the coast of Florida. The ship, loaded with gasoline, was hit by two torpedoes, setting it on fire and breaking it in two. The ship sank within eight minutes, killing all 49 of the crew.[8]
U-504's final victim was the unescorted British 5,966 GRT merchant ship Stangarth, sunk on 16 March, by a single torpedo, north-east of San Juan, Puerto Rico. There were no survivors from her crew of 46.[9] U-504 arrived back at Lorient on 1 April after 67 days at sea.
Third patrol
The U-boat then sailed for a patrol in the Caribbean Sea, departing Lorient on 2 May 1942.[10] Her first success came on 29 May when she sank the unescorted British 1,597 GRT cargo ship Allister, en route from Kingston, Jamaica, to Tampa, Florida, with a cargo of 500 tons of bananas. The ship was torpedoed 54 nautical miles (100 km; 62 mi) south of Grand Cayman Island, losing 15 of her crew of 23.[11]
On 8 June U-504 struck twice, east of the Yucatán Peninsula. At 06:59 she sank the unescorted 3,901 GRT Honduran merchant ship Tela with two torpedoes, sinking her within five minutes.[12] At 18:06 the U-boat opened fire with her deck gun on the unescorted British 1,512 GRT merchant ship Rosenborg, after missing the ship with two torpedoes. She fired 60 shells, of which about 30 hit. Four of the crew were killed, the remaining 23 were later picked up and landed in Panama.[13]
The U-boat struck again twice in a single day, 11 June, off Honduras. She sank the unescorted Dutch 4,282 GRT passenger ship Crijnssen at 02:10 with three torpedoes,[14] then the unescorted and unarmed American 4,846 GRT merchant ship American at 18:01. The ship, carrying 6,500 tons of manganese ore, coffee, gunny sacks, jute and oil, from Santos, Brazil, to New Orleans, was hit by two torpedoes, and then a third eleven minutes later. The ship sank in 25 minutes. The crew of eight officers and 30 men abandoned ship.[15] Finally, on 14 June, she torpedoed and sank the Latvian 3,280 GRT cargo ship Regent.[16] U-504 arrived back at Lorient on 7 July after 67 days at sea.
Fourth patrol
U-504 left Lorient again on 19 August 1942 and sailed south to the waters off
U-504 sank two more British merchant ships on 31 October, about 200 nautical miles (370 km; 230 mi) east of Durban. First the unescorted 7,041 GRT Empire Guidon,[20] then the unescorted 5,113 GRT Reynolds, which, hit amidships and in the stern, capsized and sank within seconds.[21]
Finally on 3 November she sank the unescorted and unarmed Brazilian 5,187 GRT cargo ship Porto Alegre en route from Rio de Janeiro to Durban, off Port Elizabeth. Hit by a single torpedo, the crew abandoned ship before the U-boat delivered the coup de grâce. Only one crew member was lost. The survivors were questioned by the Germans, and later made landfall about 50 nautical miles (93 km; 58 mi) from Port Elizabeth on 7 November.[22] U-504 arrived back at Lorient on 11 December 1942 after a patrol lasting 115 days.
Fifth and sixth patrol
U-504 left Lorient on 19 January 1943, now under the command of Kapitänleutnant Wilhelm Luis, and headed out into the Atlantic waters south of the Azores. She was subjected to attacks by unidentified Allied aircraft outbound on 21 January and inbound on 12 March, but was not damaged by either.[23] She returned to Lorient on 24 March after 65 days at sea, without making any successful attacks.[24]
Her next patrol took her to the waters south of Greenland between 21 April and 29 May 1943, again without result.[25]
Seventh patrol
U-504's final patrol began on 27 July 1943 under the newly promoted Korvettenkapitän Wilhelm Luis.
Wolfpacks
U-504 took part in six wolfpacks, namely:
- Eisbär (25 August – 1 September 1942)[27]
- Rochen (16 February – 1 March 1943)[28]
- Tümmler (1 – 22 March 1943)[29]
- Amsel 1 (3 – 6 May 1943)[30]
- Elbe (7 – 10 May 1943)[31]
- Elbe 2 (10 – 14 May 1943)[32]
