On 26 November 1804, for his 25 years' service as an officer in the Imperial Russian army, Baggovut received the Order of Saint George (4th class). During the War of the Fourth Coalition, he was known as one of the Russian army's bravest generals. On 26 December 1806, during the Battle of Pułtusk, he protected the river Narew. For this heroic act he was given the Order of Saint George, 3rd class. At the Battle of Eylau in 1807, Baggovut received orders to hold back the enemy advance to allow the Russo-Prussian troops to take possessions of the fortifications - in the course of the fighting he was seriously wounded in the chest. He also distinguished himself at the Battle of Heilsberg and at the Battle of Friedland - at the latter, he was again seriously wounded and seriously concussed, forcing him to leave the battlefield before the end of the fighting. During this military campaign he was also promoted to lieutenant general.
