U-47

U47, which belonged to the Type VIIB Class, was the ace submarine of G-Navy. In October 1939, she succeeded in crossing a blockade and penetrating the E-Navy’s base at Scapa Flow. On that very night, U-47 managed to sink the E-Country battleship Royal Oak with a torpedo. When she came back to the harbor, she was warmly welcomed and awarded the Knight’s Cross medal. In the following patrols, U47 sank numerous ships ammounting to 160 thousand tons.
