Lieutenant General Ezéchiel du Mas, Comte de Mélac who commanded a garrison of 4,095 infantry and 240 cavalrymen. Mélac was notorious for his brutal devastation of the Palatinate in 1688. Aside from the gunners, Mélac's force consisted of two battalions of the
Nettancourt Infantry Regiment, one battalion each of the
Sarre,
Bourbon and
Soissonaise Infantry Regiments, two squadrons of the
Forsac Cavalry Regiment and the
Mélac Free Company. The free company was composed of enemy deserters. Mélac's deputy was Brigadier de l'Esperoux, the infantry commander was Brigadier d'Amigny, the artillery officer was du Breuil, the engineer officer was Villars and the commander of the Crownwork was
Lieutenant Colonel Colomes. After the fortress was surrounded, a number of officers who had been on leave tried to slip through the investment to join their units inside the fortress. On 18 May, Brigadier de Guesques and
Colonel de Nettancourt were captured by
Palatine cavalry just outside the gates. D'Amigny successfully sneaked in on 16 June disguised as a peasant. During the siege the
Nettancourt Regiment was led by Colonel de Gournay. ==Siege==
