any submarines that might be in the area. The following day, the 2nd Minesweeper Flotilla took over her escort duty off Trondheim. On 17 June, Nürnberg reached Narvik, which was to be her base for the next month. During this period, one of her Arado Ar 196 floatplanes unsuccessfully attacked a British submarine. This was the only action the ship saw while in Norway. On 25 July, Nürnberg and several destroyers and torpedo boats escorted the damaged battleship Gneisenau, which had been torpedoed by a British submarine, from Trondheim, Norway, to Kiel. The flotilla arrived in Kiel on 28 July. On 8 August, KzS Leo Kreisch replaced Klüber as the ship's commander. Nürnberg spent the rest of the year in the Baltic. The Italian Admiral Mavagini visited the ship while she was in Gotenhafen in September. A short refit was conducted at Deutsche Werke in October and November. 1941–1945 On 15 February 1941, she was reclassified as a training cruiser and assigned to the Fleet Training Squadron, along with the other surviving light cruisers. These ships were tasked with training the crews for the U-boat arm, which was expanding rapidly to wage the Battle of the Atlantic. At the start of this period, many of her crewmen were themselves transferred to the U-boat fleet. After the outbreak of war with the Soviet Union in June 1941, Nürnberg was reassigned to the Baltic Fleet, which was centered on the new battleship . After it became clear that the Soviet Baltic Fleet did not intend to sortie, the German ships were dispersed. Nürnberg returned to her training duties for the remainder of the year. Another refit was conducted in January 1942; during this period, her aircraft equipment and aft torpedo tubes were removed, and her light anti-aircraft armament was increased. Allied air raids caused some damage, which delayed her return to service until 23 August. She thereafter conducted sea trials until October, after which she was deployed to Norway. On 11 November, Nürnberg left Gotenhafen, bound for Trondheim. She arrived there on 18 November, and remained there until she was transferred to Bogen Bay outside Narvik on 2 December. There, she joined the fleet in being, which was, again, centered on Tirpitz. Nürnberg saw no action during this period. On 27 April 1943, Nürnberg left Narvik for German waters via Trondheim. After arriving in Kiel on 3 May, she had her machinery
