meanwhile had raced ahead, but turned about and came back to aid the retreat of Hotspur. The German destroyers were low on fuel and ammunition, allowing Hostile and Havock to come back to aid the retreat of Hotspur. Second Battle of Narvik Shortly after the First Battle of Narvik, two more German ships were sunk by British forces. During the night of 9/10 April, the submarine intercepted and sank the light cruiser shortly after she had left Kristiansand. On 10 April, the Fleet Air Arm made a long-range attack from their base at RNAS Hatston (also called HMS Sparrowhawk) in the Orkney Islands against German warships in Bergen harbour. The attack sank the disabled German light cruiser Königsberg; On 10 April, Furious and the battleship joined the Home Fleet, and another air attack was made against Trondheim hoping to sink Admiral Hipper. Admiral Hipper, however, had already managed to escape through the watch set up outside of the port and was on her way back to Germany when the attack was launched; none of the remaining German destroyers or support ships were hit in the assault. Better luck was had in the south when severely damaged the heavy cruiser at midnight on 11 April, putting the German ship out of commission for a year. With it becoming more evident the German fleet had slipped out of Norwegian waters, the Home Fleet continued north to Narvik in the hope of catching the remaining destroyers. En route the ships suffered further harassment from German bombers, forcing them to divert to the west away from the shoreline. By 12 April, they were in range of Narvik and an aerial attack on Narvik from Furious was attempted, but the results were disappointing. It was instead decided to send in the battleship Warspite and a powerful escort force, to be commanded by Whitworth. On the morning of 13 April, Whitworth's force entered the Vestfjord using Warspites scouting aircraft to guide the way. Aside from locating two of the German destroyers, the scouting aircraft also sank an enemy submarine, the first such occurrence. Warspites destroyers travelled in advance of the battleship and were the first to engage their German counterparts which had come to meet them, thus starting the Second Battle of Narvik. Though neither side inflicted notable damage, the German ships were running low on ammunition and were gradually pushed back to the harbour. By
