In 1799, the French Directory had him and Championnet dismissed and tried for extortion before a council of war, but after the coup d'état of 30 Prairial year VI the charges against Broussier were waived and he was returned him to his rank. With his cousin Nicolas Broussier as his aide-de-camp, he continued to serve with distinction in Italy until 1803, during which time he was made commander of the place de Paris. In 1805 he was promoted to divisional general, before being made Grand Officer of the Légion d'honneur on 21 July 1809, then comte de l'Empire the following October. He returned to Lombardy that same year, taking a large part at Wagram. He then served with equal brilliance in the French invasion of Russia and the 1813 Germany campaign. He took part in the battles of Ostrovno, Borodino and Maloyaroslavets. Straight after the disasters of 1813 he was put in command of the 3rd division of the observation corps at Mainz before being put in command of Strasbourg by Napoleon, where he was promptly besieged. In 1814 he took on command of the Meuse before dying of an apoplexy at Bar-le-Duc. His name is engraved on the north side of the Arc de Triomphe, in column 7.
