U-Flotilla "Wegener"* was founded on 25 June 1938 under the command of Korvkpt. Werner Sobe. The Flotilla transferred in 1940/1941 to St. Nazaire (France). The first boat of the Flotilla, which reached St. Nazaire was U-46 under Oblt. Engelbert Endrass on 29 Sept, 1940.

In August/September 1944 most boats left the base for Norway. The last but one flotilla boat was U-267, which left St. Nazaire on 23 Sept, 1944.

After that only U-255 remained in St. Nazaire, suffering from some technical problems. After the installation of a Schnorkel the boat under the command of Korvkpt. Piening laid on 30 April 1945 mines near Les sables d'Olonne. U-255 left St. Nazaire on 7 May, 1945 as last boat and surrendered 5 days later at sea.

* Kptlt. Bernd Wegener was in WWI commander of U-27. He sank on 10 patrols 29 ships with a total of 29,402 tons. He died on 19 Aug, 1915, when his U-27 was sunk by gunfire from British U-boat-trap Baralong. The crew of Baralong killed 10 survivors of U-27 (The Baralong-incident).
