During the 1805 War of the Third Coalition, the regiment formed part of Pyotr Bagration's column. On 27 September it reached Braunau, before fighting in the Battle of Lambach, the Battle of Amstetten, and the Battle of Schöngrabern during the retreat of Kutuzov from Krems to Znaim, distinguishing itself in the latter two. For its actions at Schöngrabern, the regiment was granted one white and nine green St. George standards on 13 June 1806. It fought on the right flank at the Battle of Austerlitz, covering Bagration's retreat.
