Z19 Hermann Künne was one of six Type 1936 destroyers built for the Kriegsmarine (German Navy) in the late 1930s. Completed at the beginning of 1939, the ship spent most of her time training although she did participate in the occupation of Memel a few months later. At the beginning of World War II in September, she was initially deployed to lay minefields off the German coast, but was soon transferred to the Skagerrak where she inspected neutral shipping for contraband goods. In late 1939, Z18 Hans Lüdemann helped to laid four offensive minefields off the English coast that claimed two British destroyers and thirty-eight merchant ships.
