The Battle of Peyrestortes on 17 September 1793 saw soldiers of the First French Republic fighting troops of the Kingdom of Spain during the War of the Pyrenees. The French Army of the eastern Pyrenees, temporarily commanded by Eustache Charles d'Aoust defeated two divisions of the Army of Catalonia led by Juan de Courten and Jerónimo Girón-Moctezuma, Marquis de las Amarilas. This Spanish setback in an attempt to capture Perpignan marked the high point of their invasion of Roussillon.
