19th Lithuanian Infantry Regiment

Formed in 1812 in Samogitia^[1] in Raseiniai.

Its commander from July 13, 1812, was Colonel Konstanty Tyzenhauz,^[1] Major Pawłowski, and the battalion commanders were Radwan, Rymiński and Górski.^[2]

On August 16, 1812, Tyzenhauz reported that the regiment had been formed and bore arms.^[3]

The 19th Infantry Regiment took part in the defense of Modlin in 1813.^[1] As of May 1, 1813, the regiment's strength was 22 officers and 22 soldiers.^[4]

After Napoleon's abdication, Tsar Alexander I of Russia agreed to repatriate Polish–Lithuanian 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 Płock.^[5] However, the regiment was not recreated, as the new army provided for only 12 infantry regiments.
