The siege of Landrecies (17–30 April 1794) was a military operation during the Spring 1794 campaign in the Low Countries theatre of the War of the First Coalition.

In the amended plan de campagne that the military leaders of the Coalition agreed upon in The Hague in early April the capture of the fortress of Landrecies was a key objective.

Sébastien Le Prestre de Vauban then gave it a fortress built according to the latest military practice.

The columns of the Prince of Hessen-Darmstadt and Major-General Van der Duyn captured Catillon-sur-Sambre, near Landrecies that evening.

Two columns marched via Fontaine-au-Bois and the Forêt de Mormal toward the Sambre river, where they took the villages of Hapegarde, Etoguis and the reinforced camp of Preux-au-Bois, within range of the artillery of the fortress.

Two batteries were placed on the main approaches to the town, and work on a second, countervailing, system of trenches was prepared.

The Hereditary Prince made the chateau of Bousies his headquarters, and the Austrian auxiliaries (Hungarians, Serbs and Croats), destined to do the spadework for the entrenchments, built a camp in the forest of Mormal.

[10] Despite the severe losses the garrison commander, general Roulland, at first refused repeated demands to surrender, possibly because the French launched a desperate last attempt to relieve the fortress on 27 April, but this again came to nothing.

On 29 April an order for a sortie was refused and Roulland convened a council of war of the soldiers, as was sometimes done in the French revolutionary army.

The pressure of the council steadily increased and on 30 April Roulland gave in: he asked for a ceasefire.

Indeed the tide eventually turned in favor of the French after the Battle of Fleurus (26 June 1794), and they retook Landrecies on 17 July 1794 after a brief siege.
