Battle of Truillas The Battle of Truillas was fought on 22 September 1793 during the French Revolutionary War between the French Army of the eastern Pyrenees led by Luc Siméon Auguste Dagobert and the Spanish Army of Catalonia under Antonio Ricardos . This attempt by the French to exploit their success in the Battle of Peyrestortes ended in a Spanish victory . Part of the War of the Pyrenees , the battle was fought near the village of Trouillas in the French department of Pyrénées Orientales , 12 km southwest of Perpignan . Background . Since invading French Rousillon on April 1793 , Captain General Ricardos and his Spanish army won a string of successes over the defending forces of the First French Republic . The Siege of Bellegarde ended with a French capitulation on 24 June 1793 . Since June , the Spanish army maintained itself a few kilometers south of Perpignan , the department capital . In early September , Ricardos made a bid to isolate and capture the fortress of Perpignan by sending two divisions around its western side to cut the road to Narbonne . Meanwhile he bombarded the city from the south . French troops under General of Division Eustache Charles d ' Aoust and General of Brigade Louis Antoine Goguet attacked the positions of Spanish Lieutenant General Jerónimo Girón - Moctezuma , Marquis de las Amarilas at Peyrestortes and Lieutenant General Juan de Courten at Le Vernet . The resulting Battle of Peyrestortes on 17 September was an important French victory . The badly shaken Spanish army regrouped near Trouillas . The day after Peyrestortes , General of Division Luc Siméon Auguste Dagobert was appointed commander of the Army of the Eastern Pyrenees . Desiring to take advantage of the recent victory and urged on by Representative - on - mission Claude Fabre , Dagobert decided to attack Ricardos in his camp at Trouillas . Battle . Trouillas nestles in a plain on the Canterrane stream at an altitude of about 100 meters . Mas Deu , an establishment founded by the Knights Templar in medieval times , is located 2 . 4 km to the east . Thuir lies five km to the northwest . Ricardos defended these positions with a force of 17 , 000 soldiers and 38 cannons . The second battalion of the " Barcelona " Infantry Regiment arrived , but this reinforcement did not make up for the heavy Spanish losses suffered at Peyrestortes . Dagobert attacked the Spanish defenses with 22 , 000 soldiers . The French order of battle included the 7th , 61st , 70th , and 79th Infantry Demi - Brigade s , as well as the National Guards of Gers and Gard . Dagobert preferred to envelop the Spanish position from the west , but Fabre and the other generals persuaded him to make a frontal attack . So he sent General of Brigade Louis Antoine Goguet ' s division to assault the Spanish left flank at Thuir while sending a flanking column to attack that town from the west . D ' Aoust ' s division was ordered to attack the Spanish right flank at Mas Deu , while Dagobert led his own division in an attempt to pierce the Spanish center . Believing that Thuir was the focus of the main French effort , Ricardos posted General Crespo and only 3 , 000 men to defend the Spanish right . He shifted the troops of LG Pedro Téllez - Girón , 9th Duke of Osuna and LG Luis Firmin de Carvajal , Conde de la Union to hold Thuir . Dagobert ' s attack pushed back the Spanish center and forced its way into the main camp at Trouillas . Meanwhile , Goguet ran into a concentration of Spanish infantry and artillery on the west flank at Thuir and was beaten . Ricardos personally led a cavalry charge to break up the flanking column , then he returned to the crisis of the battle in the center . D ' Aoust merely skirmished with Crespo near Mas Deu and never mounted a serious threat to the Spanish right . This allowed Ricardos to mass his cavalry against Dagobert ' s division . After disposing of Goguet , de la Union marched to Trouillas to take the French center in reverse . Three French demi - brigades were surrounded and many prisoners taken . After an all - day battle Dagobert retreated northeast to Canohès . The Spanish victory was also helped by disorganization and poor logistical arrangements on the part of the French . Result . Though Dagobert admitted only 1 , 500 casualties , historian Digby Smith notes that the French actually suffered 3 , 000 killed and wounded , with 1 , 500 soldiers and 10 artillery pieces captured . The Spanish army lost a total of 2 , 000 killed , wounded , and missing . De Courten and General Diego Godoy also fought for the Spanish . Representatives Fabre and Raymond Gaston removed the unsuccessful Dagobert from command of the army on 28 September and temporarily replaced him with d ' Aoust . Dagobert returned to the Cerdagne with his division and sacked the Spanish town of Camprodon on 4 October . Though Ricardos gained the victory at Trouillas , he soon found it expedient to withdraw to the Tech River . On 3 October , the Spanish commander and 15 , 000 troops repulsed d ' Aoust and 16 , 000 Frenchmen at Le Boulou on the Tech . In that action , 1 , 200 French soldiers became casualties against only 300 Spaniards .
