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 ten enemy ships were destroyed by Foreign U-boats through the entire war. Eight of these were destroyed by GS UA (1939), which was a modified Type IX U-boat originally built for the Turkish Navy. However, some were effective as minelayers.
