In the Battle of Tordesillas, Battle of Villa Muriel or Battle of Palencia between 25 and 29 October 1812, a French army led by Joseph Souham pushed back an Anglo-Portuguese-Spanish army commanded by Arthur Wellesley, Marquess Wellington. After its failed Siege of Burgos, the 35,000-man Allied army withdrew to the west, pursued by Souham's 53,000 French soldiers. On 23 October, French cavalry attacked the Allied rear guard in the inconclusive Battle of Venta del Pozo. The Allies pulled back behind the Pisuerga and Carrión Rivers and took up a defensive position.
