The last three divisions were the engine room personnel. When Bismarck left port, fleet staff, prize crews, and war correspondents increased the crew complement to over 2,200 men.[8] Roughly 200 of the engine room personnel came from the light cruiser Karlsruhe, which had been lost during Operation Weserübung, the German invasion of Norway.[9] Bismarck's crew published a ship's newspaper titled Die Schiffsglocke (The Ship's Bell);[10] this paper was only published once, on 23 April 1941, by the commander of the engineering department, Gerhard Junack.[11]
