In the Battle of Majadahonda on 11 August 1812, a British-Portuguese cavalry force under Major-General George Bock and Brigadier-General Benjamin d'Urban fought a French cavalry division led by General of Division Anne-François-Charles Trelliard. The French scored an initial success by routing a Portuguese cavalry brigade and seizing three artillery pieces. Later, the French withdrew when reinforcements arrived in this Peninsular War action. Majadahonda is located 16 kilometres (9.9 mi) and Las Rozas is 17 kilometres (10.6 mi) northwest of Madrid.
