The Battle of Collioure (20–23 December 1793) saw troops from Spain attack a French division during the War of the Pyrenees.

The Spanish troops led by Gregorio García de la Cuesta were completely successful in ousting the French under Louis Pierre François Delattre from Collioure, Fort Saint-Elme and Port-Vendres.

[4] In the Battle of Peyrestortes on 17 September, the leaderless army scored a victory thanks to Generals Eustache Charles d'Aoust and Jacques Gilles Henri Goguet and Representative Joseph Cassanyes.

[2] Ricardos defeated Dagobert at the Battle of Truillas on 21 September, though the Spanish afterward retreated to the Tech River valley.

The new commander Louis Marie Turreau finally arrived on 11 October and was aghast at the way the representatives ordered around the generals.

Because of a missed communication between the War Office and army headquarters, Turreau decided to allow Aoust to continue in acting command while he sat on the sidelines and wrote complaining letters to his political friends.

[2] Doppet found the army in a terrible state, the men badly equipped and the horses and mules dying from lack of feed.

On 6 December, Doppet received information that the Spanish planned to attack Villelongue-dels-Monts the next day and tried to warn the garrison.

[7] In order to break contact with the enemy and draw his army back into winter quarters, Doppet planned an attack on Villelongue.

The attempt was a success and Delattre's troops were compelled to abandon their positions after the Spanish captured 300 French soldiers and 20 field pieces.

[10] As the retreating French approached Fort Saint-Elme and Port-Vendres, both places shut their gates, refusing to admit the soldiers.

The Army of Catalonia rushed in pursuit, Ricardos sending his cavalry across the Tech at Brouilla in an attempt to envelop the French from the east.

[9] Jerónimo Girón-Moctezuma, Marquis de las Amarillas pursued in the center with 6,000 Spanish troops while Portuguese general John Forbes with five battalions closed in menacingly from the west.

[13] In the crisis, Catherine-Dominique de Pérignon's brigade blocked the Portuguese at Saint-Luc, causing Ricardos to hesitate and allowing the French to scramble to safety.

Even so, the French lost 7,700 men and 23 guns before they reached a secure position at Perpignan[9][note 1] and its entrenched Camp de l'Union.

The new French commander Jacques François Dugommier came with 10,500 troops after successfully concluding the Siege of Toulon in December.
