German submarine U-76 was a Type VIIB U-boat of Nazi Germany's Kriegsmarine during World War II. She played a minor role in the Battle of the Atlantic, but was destroyed south of Iceland.

History[edit]

Construction[edit]

She was laid down at Bremer Vulkan in Bremen on 28 December 1939 as yard number 4. She was launched on 3 October 1940 and commissioned on 9 December.

U-76 was available for service from March 1941 following the completion of her working-up period and sea trials. Her commander, Kapitänleutnant (Kptlt.) Friedrich von Hippel, had previously served in U-144 during her trials until November the previous year.

War patrol[edit]

Six days into her first and only patrol on 2 April, U-76 sank the Finnish steam merchant ship SS Daphne which was on her way to Lillehammer, Norway. All twenty-two crew members were killed in the attack.[5][6]

The next day, U-76 followed the mostly British convoy SC 26 travelling from Sydney, Nova Scotia to Liverpool. The U-boat fired a torpedo at the British merchantman SS Athenic, disabling the vessel. The 40 people aboard were rescued by HMS Arbutus.[6]

The attack attracted the attention of the armed escort vessels, who pinpointed her position. Deploying depth-charges from HMS Wolverine and Scarborough, U-76 was sunk. Forty-two of her forty-three-man crew survived and were captured.
