Battles of Narvik
During Operation Weserübung, the German invasion of Norway, Wilhelm Heidkamp was the flagship of the Kriegsmarine force assigned to attack Narvik. On 9 April 1940, Wilhelm Heidkamp sunk the old Norwegian coastal defense ship Eidsvold with torpedoes after an attempt to get the ship to surrender failed. The next day, five British destroyers engaged the German force in the First Naval Battle of Narvik. During the battle, Wilhelm Heidkamp was sunk and its commander, Commodore Bonte, was killed
