Born on 20 October 1760 at Lorry-Devant-le-Pont, in the Kingdom of France, Roget entered military service in the 7th regiment of chasseurs a cheval, on 13 May 1777, as a simple trooper. In 1793, as a sous-lieutenant he served in Custine's army at the Siege of Mainz. Later he served with Marceau-Desgraviers and Kleber to quell the Vendee uprising. By the end of uprising in the Vendee, he had reached the grade of adjutant general. Recalled to the Army of the Rhine and Moselle, General Desaix gave him command of the 13th Dragoon Regiment, which had achieved battle honors at Valmy four years earlier; at the Battle of Dierstein, he led the 13th in a charge and defeated the Austrian Regiment D'Alton, taking two flags and five cannons. He then turned to Offenburg, where he chased out the Austrians and pursued them beyond Gengenbach; in the second action, he took four guns from the Austrians, as well as forty boxes of ammunition, and a large number of prisoners. In the Swiss Campaign of 1799, under overall command of Massena, he led the 13th Dragoons in Brigadier General Oudinot's division in the Alpine Rhine. He was instructed to cross the Rhine at a ford near Verdenberg. The sudden rise of the river made this impractical and several troopers drowned in the attempt. Colonel Roget led his regiment across the river under fire from Habsburg sharpshooters concealed on the other side; having reached the east bank, he ordered the remaining dragons on the far bank to bring the artillery across. Under the cover of artillery fire, Roget drove the Austrian defenders back past the village of Eschen. The next day, after a lively fight, Colonel Roget led a successful cavalry charge against the Regiment O'Donnell and Regiment Modena, taking a number of prisoners, five cannons, and 200 horses. Subsequently, he was promoted to general of brigade. In 1799, under command of Michel Ney, he participated in the Battle of Winterthur. He commanded the 13th Dragoons. He fought at the Battle of Austerlitz, where he also commanded the 10th and 11th dragoons, of Walther's division. By 30 December 1806, he had been promoted to general of division and in 1808, he commanded the 3rd division at Metz. In January 1813, the Allied offensive had reached the border regions between the German states and France. In anticipation of invasion, MarshalMarmont investigated all preparations for the defense of Metz, and found the state of troops and defenses lacking. He accused Roget of gross incompetence, and removed him from his post as military commander of Metz, appointing Durette in his place. Upon the Bourbon Restoration, Roget retired to Remelfing where he died on 9 January 1832.
Roget married Marie Françoise Josephine Bourste. They had three children: Dominique-François-Louis, Marie-Antoine-Françoise Susanne, and Napoleon-Henri-Joseph.
