U-4 operated off the Norwegian coast 4 September through 14 September 1939; and again from 19 September through 29 September 1939.  Her last combat patrol covered 11 March through 14 April 1940 before she was transferred from combat duty to a training flotilla where she became a schulboot (school boat).

U-4 was decommissioned on 1 August 1944 and surrendered to the Allies in May of 1945.  She was broken up by the Allies after the war.

Many thanks to our friend and Sharkhunters Member since 1987 GEORG HÖGEL for all the conning tower emblems used in our monthly KTB Magazine and also here on the pages of our website.  GEORG was radioman aboard U-30, the first boat into combat, the first to sink a ship (the liner ATHENIA) and the first into an occupied French port.  When that Skipper (Lemp) took command of U-110, GEORG was one of the former crew to transfer to the new boat under Lemp.  After the war, he was Professor of Art at a major German university.
