German Junkers Ju 88 aircraft unsuccessfully attacked the Home Fleet with bombs. Four destroyers joined the Home Fleet at around 7 pm. Tovey considered raiding German positions in Norway, but decided against this and instead set course for Scapa Flow. The Home Fleet, which had been reinforced with a further eight destroyers, arrived at Scapa Flow at night on 10 March. On 9 March , one of two armed Norwegian whalers that had been dispatched from Iceland to strengthen PQ 12's escort, capsized while searching for the convoy. Only three members of her crew were rescued by the other whaler, which then proceeded directly to Murmansk. Tirpitzs crew completed repairs to the battleship's engines 48 hours after her arrival at Narvik. She departed the port with an escort of five destroyers just before midnight on 12 March. Guided by Ultra intelligence and reports from resistance agents in Norway, a force of eight British destroyers under the command of Captain Alan Scott-Moncrieff attempted to intercept the German force between Trondheim and Bodø that night. They did not make contact, and were forced to turn away from the coast at 3:30 am to avoid being attacked by German aircraft once dawn broke. Four British submarines stationed along the route between Narvik and Trondheim were also unable to attack the German ships. Tirpitz anchored near Trondheim at 9 pm on 13 March. The British received reports of her arrival there from Norwegian agents and these were confirmed by a photo reconnaissance aircraft on 18 March. Both convoys reached their destinations without further loss. QP 8 arrived at Reykjavik in Iceland on 11 March. Most vessels of PQ 12 reached Murmansk on 12 March, but several that had become separated from the convoy arrived in Russian ports on other dates. One of the Norwegian whalers assigned to PQ 12 shot down a German aircraft while it was attempting to bomb a merchant ship on 13 March. This was the only attack on the convoy during its voyage. Two of the four German submarines that were operating off Murmansk spotted ships from PQ 12 as they approached the port, but neither was able to attack. Aftermath Assessments The British were disappointed by their failure to sink or damage Tirpitz. Following the operation Tovey was critical of the instructions he had received from the Admiralty. He believed that the order to prioritise the defence of the
