Upon arrival in Cantabria the cavalrymen marched to Extremadura where they were to collect horses, thus avoiding the defeat that fell upon Romana's division at Espinosa de los Monteros. In 1809 the regiment would see much action while serving in Gregorio García de la Cuesta y Fernández de Celis' Army of Extremadura, as part of General José de Henestrosa's 1st Cavalry Division. It would fight at the Battle of Talavera, where they captured four French cannons and would be highly praised in Cuesta's report.
