Promoted to the rank of Major on 18 May 1794, in July he joined the Corps of General Karol Sierakowski and distinguished himself in the battles of Krupczyce and Terespol. For his bravery on the field of battle he was awarded with the Ojczyzna Obrońcy Swemu ring (number 38), the replacement for the Virtuti Militari medal abolished soon before. Wounded during the disastrous Battle of Maciejowice, he nevertheless managed to lead his forces out of the Russian encirclement and reach Warsaw, where king Stanisław August Poniatowski promoted him to the rank of Colonel.
