War of the Pyrenees: France defeats a Spanish force at the Battle of Peyrestortes.

The War of the Pyrenees, also known as War of Roussillon or War of the Convention, was the Pyrenean front of the First Coalition's war against the First French Republic. It pitted Revolutionary France against the kingdoms of Spain and Portugal from March 1793 to July 1795 during the French Revolutionary Wars.

At the Battle of Peyrestortes in the War of the Pyrenees, soldiers of the First French Republic defeated a Spanish army that had invaded Roussillon and was attempting to capture Perpignan. The Spanish army of Antonio Ricardos had occupied part of Roussillon and made an abortive attempt to seize the fortress of Perpignan in July 1793. At the end of August, the Spanish commander sent two divisions on a sweep around the western side of Perpignan in an attempt to isolate the fortress and choke it off from resupply. After an initial Spanish success, the French army commander Hilarion Paul Puget de Barbantane, lost his nerve and fled from the area.
