Formed pursuant to a resolution of the Confederation and the Grodno County of July 3, 1812, in Vilnius, Lithuania. Originally under the name of the 1st Lithuanian Infantry Regiment.
Its commander from July 13, 1812, was Colonel Aleksander Franciszek Chodkiewicz, Major Suhr, and the battalion commanders were TrÃÂbicki, SÃ Âupecki, and Roland. In July 1812, a large group of deserters and prisoners of war from the Imperial Russian Army joined the regiment.

The regiment took part in the defense of Modlin in 1813. As of May 1, 1813, the regiment's strength was 54 officers and 824 soldiers.
After Napoleon's abdication, Tsar Alexander I of Russia agreed to repatriate PolishâÂÂLithuanian units. They were to serve as a base for the formation of the Army of Congress Poland under the command of Grand Duke Konstantin. On June 13, 1814, the regiment was assigned a concentration site in Bydgoszcz. However, the regiment was not recreated, as the new army provided for only 12 infantry regiments.
