Львовско-Сандомирская операция
In the summer of 1944, after Lvov–Sandomierz Offensive, Red Army pushed the Wehrmacht from eastern Lesser Poland. The city of Lublin was captured by the Soviets on 22 July 1944, Stalowa Wola – on 1 August, and Sandomierz, on the left bank of the Vistula – on 18 August. The front line stabilized along the Vistula for about six months (with some bridgeheads on the western bank on the Vistula – see Battle of Studzianki), and in early 1945, Soviet Vistula–Oder Offensive began, which pushed Germans to the gates of Berlin. The Soviets entered Kielce on 15 January, Częstochowa – on 17 January, and Kraków on 19 January. On 27 January, the Red Army entered Sosnowiec. In took the Soviets much longer to clear the areas in the mountains – they did not enter Żywiec until 5 April 1945.
