German submarine U-157 was a Type IXC U-boat of the Nazi German Kriegsmarine during World War II. The submarine was laid down on 21 October 1940 at the AG Weser yard in Bremen, launched on 5 June 1941, and commissioned on 15 September under the command of Korvettenkapitän Wolf Henne. After training with the 4th U-boat Flotilla, U-157 was transferred to the 2nd U-boat Flotilla for front-line service on 3 June 1942.[5]

Service history

1st patrol

U-157 sailed from Kiel on 30 April 1942, around the British Isles, and arrived at Lorient, France, eleven days later on 10 May.[7]

2nd patrol

The U-boat left Lorient on 18 May 1942 and sailed across the Atlantic to the Caribbean Sea.[8] There, on 11 June, she torpedoed and sank[9] the unescorted 6,401-ton American tanker Hagan about five miles off the north coast of Cuba. The ship, loaded with 22,676 barrels of blackstrap molasses, was hit in the engine room, destroying the engines and causing at least one boiler to explode. About a minute later a second torpedo struck, and the tanker began to sink by the stern. The crew abandoned ship in two lifeboats, but two officers and four crewmen were lost. The boats, containing 38 men, both landed in Cuba.[10]

U-157 was sunk two days later, on 13 June, south-west of Key West, in position 24°13′N 82°03′W / 24.217°N 82.050°W / 24.217; -82.050, by depth charges from the US Coast Guard cutter USS Thetis. All 52 crew were lost.[5][11]
