German interest in Bergen was based on it’s strategic position close to British Isles, and the fact that it was Norway’s second largest city.  Battle Group 3, consisting of the cruisers Koeln and Koenigsberg, the service ships Bremse and Karl Peters, 3 torpedo boats, 5 motor torpedo boats, and 1,900 troops, departed from Wilhelmshaven for Bergen at 00:40 on April 8th.  At 04:30 the convoy paused and troops were disembarked for an assault on Kvarven.  At 05:15 Norwegian batteries fired on the ships, hitting the Koeningsberg three times and the Bremse once.  The Koeningsberg was damaged and unable to continue.  ( Picture on right of the damaged Koeningsberg harbored in Bergen, from Kurt Monsen at http://home.sol.no/~kurtmon/ndWW2.html ) At 09:30 the Norwegian batteries at both Sandviken and Kvarven were defeated by the Germans.  Very little resistance was put up by the city of Bergen, and it was easily occupied.  From there the German military began advancing eastward.  On the morning of the 26th they took Voss, and on May 1st, Norwegian troops surrendered at Myrdal.
