War of the Pyrenees: Forces from the French Army of the Eastern Pyrenees defeated two divisions of the Army of Catalonia, ending the furthest Spanish encroachment in their invasion of Roussillon.

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.

The Army of the Eastern Pyrenees was one of the French Revolutionary armies. It fought against the Kingdom of Spain in Roussillon, the Cerdanya and Catalonia during the War of the Pyrenees. This army and the Army of the Western Pyrenees were formed by splitting the original Army of the Pyrenees at the end of April 1793 soon after the war started. Shortly after the Peace of Basel on 22 July 1795, the fighting ended and the army was dissolved on 12 October that same year. Many of its units and generals were transferred to join the Army of Italy and fought under Napoleon Bonaparte in 1796.

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.

Roussillon was a historical province of France that largely corresponded to the County of Roussillon and part of the County of Cerdagne of the former Principality of Catalonia. It is part of the region of Northern Catalonia or French Catalonia, corresponding roughly to the present-day southern French département of Pyrénées-Orientales in the former region of Languedoc-Roussillon.
