Foreign U-boats
Foreign U-Boats was the title for a special section created by Nazi Germany's Kriegsmarine that adopted 13 captured enemy submarines and a single Turkish vessel into the U-Boat corps. Beginning in 1939 and lasting until the end of World War II in 1945, the Kriegsmarine modified a total of 13 captured enemy submarines, then deployed them into combat with German crews. The special corps was not especially successful, as only nine enemy ships were destroyed by Foreign U-Boats through the entire war. Seven of these were destroyed by, which was a modified Type IX U-Boat originally built for the Turkish Navy. However, some were effective as minelayers.The captured submarines
