German submarine U-407 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. She was laid down on 12 September 1940 by Danziger Werft, Danzig as yard number 108, launched on 16 August 1941 and commissioned on 18 December 1941 under Oberleutnant zur See Ernst-Ulrich Brüller.

Service History[edit]

The boat's career began with training at 5th U-boat Flotilla on 18 December 1941, followed by active service on 1 September 1942 as part of the 9th Flotilla. However, within 3 months, she transferred for operations in the Mediterranean with 29th Flotilla for the remainder of her service.

In twelve patrols she sank three merchant ships, for a total of 26,892 gross register tons (GRT), one merchant ship damaged of 6,207 GRT, two warships damaged (17,900 tons) and one more ship a total loss 7,176 GRT; however, some sources claim that the damaging of the HMS Newfoundland is to be attributed to the Template:Ships.[3]

  • Vorwärts (25 August – 26 September 1942)
  • Tiger (26–28 September 1942)
