The incomplete Gerard Callenburg was  scuttled by the Dutch in 1940. Raised by the Germans in the same year and commissioned on 11.10.1942. Renamed to ZH1 served most of its time as a experimental ship in the Baltic Sea. First attached to the 5th Z-Flottila, later reassigned to the 8th Z-Flottila, in 1943 sent to France together with Z27 . Used to covering blockade breakers and U-Boats. After the Invasion on D-Day, ZH1 , Z32 , Z24 and T24 were ordered to attack the invasion fleet on 08.06.1944. Near Ile de Bas, the German ships encountered the British destroyers Tartar , Ashanti , Eskimo and Javelin , the Canadian Haida and Huron and the Polnish Blyskawica .
During this battle, ZH1 was damaged severely, but was able to damage the Tartar until a torpedo fired by the Ashanti cut off the entire bow section. ZH1 sunk after its depth charges exploded.
