With the outbreak of the War of the Third Coalition, Dupas was given a command in the Grande Armée, leading an epic attack at the Battle of Austerlitz, where his men were instrumental in forcing 5,000 Russians to surrender. For this action, he was promoted to General of Division, before taking part to the War of the Fourth Coalition of 1806-1807, where he was noted above all for his spirited actions at the Battle of Straslund and Battle of Friedland. He was created a Count of the Empire at the beginning of 1809 and fought at the great Battle of Wagram in July of that year. Dupas was then placed on the retired list, due to the various infirmities that he was suffering from, following his many battle wounds. He was recalled in 1813 for the War of the Sixth Coalition, but was permanently placed on the retired list in November of that year. He retired in Chateau de Ripaille in thonon-les-Bains where he died on 6 Mar 1823. http://charlesnealselections.com/wine/savoie/ripaille-vin-savoie/
