225th victory. On 14 October 1943, he became the first pilot to reach 250 victories, following his 442 combat missions. Nowotny was celebrating this feat in the Ria Bar in Vilna when he received a phone call from Hitler himself, announcing that he had been awarded the Knight's Cross of the Iron Cross with Oak Leaves, Swords and Diamonds (), making him the eighth of 27 men to be so honored. The Brillanten (Diamonds) were presented by Hitler at the Wolfsschanze, near Kętrzyn (German: Rastenburg) on 19 October 1943. Nowotny immediately went on a short vacation to Vienna before returning to his front-line unit. On 29 October 1943, Nowotny presented the Knight's Cross of the Iron Cross to Oberfeldwebel Otto Kittel. In the days following, Nowotny flew as wingman to Karl Schnörrer, helping him accumulate further victories. On 11 November, Anton Döbele was killed when he rammed an Il-2 Sturmovik. The next day, 12 November 1943, Schnörrer was severely injured after bailing out at low altitude. Schnörrer was replaced as Nowotny's wingman by Unteroffizier Ernst Richter. With Richter, Nowotny claimed his final two aerial victories on the Eastern Front on 15 November 1943. In total, Nowotny had claimed 255 confirmed kills plus a further 50 unconfirmed, before he was taken off combat duty. Nowotny was sent on a propaganda tour in Germany, which included the presentation of the Knight's Cross of the War Merit Cross () to the railroad engineer August Kindervater on 7 December 1943 – Nowotny's 23rd birthday. Shortly before Christmas, he visited the Focke-Wulf production site at Bad Eilsen, where he was met by Professor Kurt Tank. The mayor of Vienna, Dipl.-Ing. Hanns Blaschke awarded Nowotny the city's ring of honour on 11 January 1944, the presentation taking place a week later. It was a token that Nowotny accepted reluctantly, feeling that he did not deserve it. His next official visit was the Büromaschinenfabrik (office machinery factory) at Zella-Mehlis, before he briefly returned to Jagdgeschwader 54. Nowotny was made Geschwaderkommodore of Jagdgeschwader 101 (JG 101) and commander of the Jagdfliegerschule 1, a Luftwaffe fighter pilot training school at Pau in southern France, in April 1944. Kommando Nowotny and death In September 1944, Nowotny was made commander of a specialist unit dubbed Kommando Nowotny, flying the newly developed Messerschmitt Me 262 out of airfields near Osnabrück. The unit not only had to contend with the enemy, but also
