3rd Shock then took part in the blockade of the Courland pocket, and the first Soviet attacks started on 16 October. However, by the end of October, it was seen that despite some advances, there was little hope for full success, and the Army was shifted south. 3rd Shock became part of the 1st Belorussian Front from 31 December 1944. The Army was placed in the second echelon for the Warsaw–Poznań strategic offensive operation, attacking in the direction of Poznań under Zhukov's 1st Belorussian Front. It then took part in the Vistula–Oder Offensive between 12.1.1945 – 3.2.1945.
