"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 hull, and the explosive shock damaged one of her three turbines. Her captain ordered the ship to stop while temporary repairs were conducted, which lasted for about 30 minutes. By 03:50 on 13 February, the ship had reached Helgoland.
