On the last day of the battle, the French overran a key position and put the Spanish army to rout.

A Spanish artillery shell killed Dugommier early in the battle and Dominique Catherine de Pérignon assumed command of the French army.

These battles and other actions resulted in Spanish forces overrunning part of Roussillon, where France borders Spain on the Mediterranean Sea.

Augereau advanced on the right flank while Pérignon moved forward in the center, supported by General of Brigade Charles Dugua's cavalry reserve.

Attacks by Pérignon in the center and Sauret on the left failed in the face of intense Spanish artillery fire from the area of Capmany.

[9] On the morning of 18 November, Dugommier, Representative-on-mission Pierre Delbrel, and staff officers watched the combat from the summit of Montroig.

French troops soon began assaulting the 25-gun redoubt at the Santa-Maria-del-Roure monastery, 2 kilometres (1.2 mi) northwest of Pont de Molins.

[9] During the early fighting on the 20th, de la Union remained at his headquarters in the San Fernando (Sant Ferran) fortress at Figueres.

During the subsequent melee, de la Union was fatally hit by two bullets and fell about 300 metres (328 yd) from Santa-Maria-del-Roure.

[11] De Courten and General Domingo Izquierdo withdrew the left wing south to Bàscara, behind the Rio Fluvià, pursued by Verdier.

An isolated force of 2,000 troops retreated from Llers to Figueres, where it joined Brigadier General José Andrés Lopéz Valdes' 7,000-man garrison of San Fernando Fortress.

De las Amarilas took command of the badly shaken Army of Catalonia and marched toward Girona, leaving a rear guard to cover the retreat.

The French army quickly seized Figueres, but at first the fortress of San Fernando, which was 1.3 kilometres (0.8 mi) northeast of the city, defied them.

[12] In December, de las Amarilas was dismissed for disgracefully abandoning San Fernando, and for blunders at the battles of Boulou and Peyrestortes.
