Pierre-Antoine, comte Dupont de l’Étang (4 July 1765 – 9 March 1840) was a French general of the French Revolutionary and Napoleonic Wars, as well as a political figure of the Bourbon Restoration. His exploits, encountered during a 19 year long conflict with brother officer François Fournier-Sarlovèze, are the stuff of legends.
Born in Chabanais, Charente, Pierre first saw active service during the French Revolutionary Wars, as a member of Maillebois legion in the Netherlands, and in 1791 was on the staff of the Army of the North under General Theobald Dillon. He distinguished himself in the Battle of Valmy, and in the fighting around Menen in the campaign of 1793 he forced an Austrian regiment to surrender. Promoted Brigadier General for this accomplishment, he soon received further advancement from Lazare Carnot, who recognized his abilities. In 1797 he became Général de Division.
The rise of Napoleon Bonaparte, whom he supported in the 18 Brumaire Coup (November 1799), brought him further opportunities under the Consulate and Empire. In the campaign of 1800 he was chief of staff to Louis Alexandre Berthier, the nominal commander of the Army of Peierve of the Ains which won the Battle of Marengo. After the battle he sustained a successful combat, against greatly superior forces, at Pozzolo.
In the campaign on the Danube in 1805, as the leader of one of Michel Ney’s divisions, he earned further distinction, especially in the Battle of Haslach-Jungingen (Albeck), in which he prevented the escape of the Austrians from Ulm, and so contributed most effectively to the isolation and subsequent capture of Freiherr Mack von Leiberich and his whole army. He also distinguished himself in the Battle of Friedland.
