The Commonwealth was not ready for war. In 1631, the royal army numbered barely 3,000 men; the Smolensk garrison was about 500 strong, and most garrisons in the border area were composed not of regular or mercenary soldiers but of 100 to 200 local volunteers. Aware that Russia was preparing for war, in the spring of 1632 the Sejm (Polish–Lithuanian parliament) increased the army by recruiting an additional 4,500 men; by mid-1632 the deputy voivode ("podwojewoda") of Smolensk, Samuel Drucki-Sokoliński, had about 500 volunteers from pospolite ruszenie and 2,500 regular army soldiers and Cossacks. In May the Senate of Poland agreed to increase the size of the army, but Grand Lithuanian Hetman Lew Sapieha objected, arguing that the current forces were enough and that war was not likely. Nonetheless the Field Lithuanian Hetman Krzysztof Radziwiłł recruited an additional 2,000 soldiers.
