 After another night march, on 5 March the Allies reached a hill to the south east of Barrosa, the Cerro del Puerco (also referred to as the Barrosa Ridge). Scouts reported the presence of Villatte's force, and la Peña ordered his vanguard division to advance. With the aid of a fresh sortie of Zayas's troops from Cádiz, and reinforced by a brigade of the Prince of Anglona's division, the Spanish drove Villatte's force across the Almanza Creek. La Peña refused his vanguard permission to pursue the retreating French, who were consequently able to regroup on the far side of the creek. Graham's Anglo-Portuguese division had remained behind on the Cerro del Puerco to defend the rear and right flank of la Peña's main force.
