After Valmy, the 12th Chasseurs à Cheval went north as part of the "Army of Belgium" under Pierre de Ruel, marquis de Beurnonville. Two squadrons of the regiment served in Beurnonville's Advance Guard under Auguste Marie Henri Picot de Dampierre at the Battle of Jemappes on 6 November 1792. The 12th Chasseurs fought at the Battle of Aldenhoven on 1 March 1793 from which Henri Christian Michel de Stengel brought off the army pay chest with one squadron from the regiment. At the Battle of Neerwinden on 18 March the 12th Chasseurs may have fought with the right wing. On 1 May in a preliminary action to the Battle of Raismes Bonnaud suffered a saber cut on the cheek and on 6 August he received a sword cut to his left hand at the Battle of Caesar's Camp. By this time his unit was part of the "Army of the North". On 15–16 October 1793, the 12th Chasseurs with 511 troopers fought in Jacques Fromentin's division at the Battle of Wattignies.
