The Battle of Molins de Rey or Battle of Molins de Rei or Battle of Molins del Rey (21 December 1808) saw an Imperial French corps led by Laurent Gouvion Saint-Cyr attack a Spanish army led by the Conde de Caldagues and Theodor von Reding. Saint-Cyr outmaneuvered his opponents, distracting them with a false attack in front while sending the bulk of his force across Llobregat River in a turning movement around the Spanish right flank. The Spanish defensive lines crumbled and the French captured 1,200 soldiers, all the Spanish artillery and Caldagues himself. The Peninsular War engagement was fought near Molins de Rei, located 15 kilometres (9 mi) west of Barcelona, Spain.
