They took part in the Battle of Czarnowo, where they repulsed the second French attack and under the command of Major Palibin and Lieutenant Colonel Lokhov recaptured a height on the Russian left, dislodging the French in hand-to-hand fighting and recapturing a light battery.

Their participation in the Battle of Eylau included flanking the French under Major Makhov and Captain Panov, utilising a battalion and two companies respectively.

They turned back a cavalry charge from Murat's horsemen and captured multiple prisoners, and went on to repulse attacks from Moran, Saint-Illaire and Gudin's divisions.

Under Captain Kyrlov, the 2nd battalion pursued the dislodged French, who had set fire to the only bridge across the Nischu river.

They stormed the bridge regardless and continued a pursuit of the French infantry, routing them off the field at bayonet point.
