Wanka's Bataillon (I./Grenadier-Regiment 446) and I./Grenadier-Regiment 439 were the primary German units in the effort near the end of 1943 to link up Heeresgruppen Mitte and Süd. Starting from the Paritschi on the 21.12.1943, the two Bataillonen moved south and were eventually able to link up with 4. Panzer-Division. With this act the linkage between 2. Armee and 9. Armee was achieved, and by extension that of the two Army Groups. For his share in this success Wanka received the Knight's Cross.
