[...] the new cruiser Blücher, carrying thousands of German troops, approached Oscarsborg. [...] Local commander Colonel Birger Eriksen, knowing the gunners' limitations, held his fire until the last moment. [...] One shell hit the cruiser's anti-aircraft control centre, while the other smashed into an aviation fuel store, causing a pillar of flame to leap skywards. After suffering two further hits from shore-based torpedoes, within minutes Blücher was engulfed in fire and listing heavily, her ammunition exploding. The ship sank with the loss of a thousand German lives.
