During the fighting for the Orel salient in early 1943 Oberstleutnant Flinzer and his troops fought around Wydrowka, Pustynka, Buda-Monastyrskaja and Kommuna-Bolschewik. Here they distinguished themselves greatly in the defense. In particular, on the 22.02.1943, they withstood a major Soviet offensive in the so-called “Hell of Liwadija”. Flinzer would receive the Knight’s Cross for his outstanding leadership during this time.
