''Blücher'' was the second of five heavy cruisers of Nazi Germany's ''Kriegsmarine'', built after the rise of the Nazi Party and the repudiation of the Treaty of Versailles. Named for Gebhard Leberecht von Blücher, the Prussian victor of the Battle of Waterloo, the ship was laid down in August 1936 and launched in June 1937. She was completed in September 1939, shortly after the outbreak of World War II. After completing a series of sea trials and training exercises, the ship was pronounced ready for service with the fleet on 5 April 1940. Assigned to Group 5 during the invasion of Norway in April 1940, ''Blücher'' served as ''Konteradmiral'' Oskar Kummetz's flagship. The ship led the flotilla of warships into the Oslofjord on the night of 8 April, to seize Oslo, the capital of Norway. Two old coastal guns in the Oscarsborg Fortress engaged the ship at very close range, scoring two hits. Two torpedoes fired by land-based torpedo batteries struck the ship, causing serious damage. A major fire broke out aboard ''Blücher'', which could not be contained. After a magazine explosion, the ship sank, with major loss of life. The wreck remains on the bottom of the Oslofjord. == Construction == (詳細はDeutsche Werke'' shipyard in Kiel. Her keel was laid on 15 August 1936, under construction number 246.
