Meanwhile, Field Hetman of Lithuania and Voivode of Vilnius, Krzysztof Radziwiłł, and Voivode Gosiewski established a camp about from Smolensk, moving from Orsha to Bajów and later, Krasne. By February 1633, they had amassed around 4,500 soldiers, including over 2,000 infantry, and were engaged in raiding the rear areas of the Russian besiegers to disrupt their logistics. Hetman Radziwiłł also managed to break through the Russian lines on several occasions, bringing about 1,000 soldiers and supplies into Smolensk to reinforce the fortress and raising the defenders' morale.
