they failed to explode. The third also failed to detonate. One of the 227 kg bombs penetrated the upper deck just forward of the rear gun turret, and exploded on the main armored deck. The last bomb fell on the starboard side and also detonated on the main armor deck. The ship listed at 8°, after having taken in between and of water; the list was reduced to 2° by counter-flooding. Casualties amounted to two men killed and 15 wounded. The following day Scharnhorst arrived in Brest for repairs, which lasted for four months. Operation Cerberus In early 1942, the crews of Scharnhorst, Gneisenau, and the heavy cruiser made preparations for Operation Cerberus, a daylight dash up the English Channel. The ships were to be redeployed to Norway, to assist in the disruption of convoys to the Soviet Union, as well as the defense of occupied Norway. The risk of further damage from air raids, and the loss of the Bismarck and most of the supply ships had forced a change of thinking by the naval staff on the use of these ships for Atlantic sorties. If they could not be evacuated, Hitler ordered that they were to be decommissioned in Brest. The ships left Brest late on 11 February, and remained undetected for the majority of the operation. East of Dover, a flight of six Swordfish torpedo bombers attacked the ships without result. At 15:31, Scharnhorst detonated a magnetic mine, which damaged the ship's circuit breakers enough to shut down the entire electrical system. The ship was immobilized briefly—between 15:49 and 16:01, all three turbines were restarted and the ship resumed a speed of . A series of air attacks ensued; through evasive maneuvers, anti-aircraft fire, and Luftwaffe fighters, they were all repulsed. By noon on 13 February, Scharnhorst had reached Wilhelmshaven. After two days she was transferred to Kiel for repairs, which lasted until July 1942.Gneisenau and Prinz Eugen had continued their journey to Norway while Scharnhorst was immobilized. At 14:45, the ships were attacked by five Whirlwind fighter-bombers—German fighters beat them back. Several more air attacks followed over the next two hours, without success for the British. At 16:17, five British destroyers attempted to torpedo the German ships, but heavy fire from Gneisenau and Prinz Eugen mauled one and forced the others to turn away. Near Terschelling, Gneisenau struck a mine that did minor damage to the
