Воронежский фронт
On October 20, 1943, the Voronezh Front was renamed to the 1st Ukrainian Front. This name change reflected the westward advance of the Red Army in its campaign against the German Wehrmacht, leaving Russian Soviet Federative Socialist Republic behind and moving into Ukrainian Soviet Socialist Republic. The front participated or conducted battles in Ukraine, Poland, Germany, and Czechoslovakia during 1944 and 1945.
