In the Grand Duchy of Lithuania the first phase of the war with the Tsardom ended with a total defeat of the Commonwealth. At the Battle of Shklow (1654) and the Battle of Shepelevichy the Russians destroyed the small Lithuanian force under Janusz Radziwiłł. The country laid open to the conquerors. Belarusian towns surrendered one after another and in 1654 Smolensk fell after a three-month-long siege. The next year the Russians took Minsk, Grodno (Hrodna) and Vilnius. With the simultaneous Swedish war disasters the Commonwealth had to accede in 1656 to the Truce of Vilnius accord.
