On 24 December, Augereau forced a crossing of the Wkra River in Poland in the Battle of Czarnowo. He sent Étienne Heudelet de Bierre's 2nd Division to attempt a passage at Sochocin, while Desjardin tried to cross at Kołoząb. A Russian division under Michael Andreas Barclay de Tolly opposed the French. Heudelet's attack was repulsed, but Desjardin met with success. Desjardin pinned down the Russians with covering fire, while some elite companies stormed across the partially destroyed bridge. Pierre Belon Lapisse led Desjardin's other brigade in a flank attack. The combined assault drove off the Russian defenders and captured six field pieces.
