Siege of Fort-Louis (1793)

The siege of Fort-Louis (14 October – 14 November 1793) saw a force composed of Habsburg Austrians, Hessians and Bavarians led by Franz von Lauer lay siege to Fort-Louis which was held by a Republican French garrison under Michel Durand. The French capitulated after a defense lasting exactly one month. The siege occurred during the War of the First Coalition, part of the French Revolutionary Wars. In 1793 the fortress was sited on an island in the Rhine River, but today Fort-Louis is a village in the Bas-Rhin department in France.

Dominique-André de Chambarlhac supervised the technical elements of the defense. Altogether, Fort-Louis mounted 111 artillery pieces. General-major Franz von Lauer commanded the 4,700-man besieging force which included a siege train of 55 guns. Lauer commanded three battalions of the Combined Bavarian Regiment, one battalion from the Hessian Leib Regiment, the Hessian Leib Grenadier Battalion, one Austrian battalion from an unknown regiment and two squadrons of the Szekler Hussar Regiment.
