Fearing that the outbreak in Nancy would spread to the other garrisons located along the frontier, the
National Constituent Assembly in Paris ordered suppression of the mutiny. The Assembly concerned at the increasing indiscipline had already voted to abolish political associations within the army. General
François Claude de Bouillé, army commander at
Metz, accordingly led 4,500 regular soldiers and
national guardsmen to Nancy on 18 August. De Bouillé, a committed royalist, was later to be a leading force in
Louis XVI's attempted
flight to Varennes. Upon arrival at the city on 31 August, de Bouillé issued an ultimatum to a delegation from the mutinous soldiers demanding the release of their officers and the handing over of four ring-leaders. These terms appeared acceptable to the majority of the soldiers, but before they could be implemented, a clash occurred at the
Stainville Gate, where the advance ranks of de Bouillé's forces were halted before an artillery piece manned by soldiers of the
Régiment du Roi.
Antoine-Joseph-Marc Désilles, a junior officer of the
Régiment du Roi, stepped in front of a
24-pounder cannon loaded with canister in an attempt to dissuade the mutineers from firing on the government troops. He was shot down, and in the confusion the cannon was fired, killing about 60 of the loyal troops drawn up in close formation a few paces away. A general engagement then broke out, and after three hours of fighting, de Bouillé's troops put down the mutiny with heavy casualties amongst soldiers and civilians. Total deaths were estimated at 500. ==Aftermath==
