On 27 December 1811 he took command of the 10th Infantry Regiment, becoming a colonel. In 1812 his regiment took part in the personal review by the emperor himself in Königsberg and he then joined 7th Division of the 10th Corps of the Grande Armée under Jacques MacDonald, being assigned to general Rappa's corps. After winning a series of clashes with Russian troops, he retired to Gdańsk where he led numerous assaults, defensive actions and nighttime sallies beyond the town walls.
