The Battle of Majadahonda Historical milestone · Majadahonda, Área Metropolitana, Madrid Image of Majadahonda, not of the place itself. The Battle of Majadahonda was fought on 11 August 1812, during the Peninsular War. The French cavalry under General Treilhard surprised the Anglo-Portuguese vanguard which, under the command of Brigadier D'Urban, was marching at the head of Wellington's army and had occupied Majadahonda and Las Rozas that morning. The Portuguese did not resist and fled, abandoning three cannons and almost two hundred men; the French galloped as far as Las Rozas and spread panic through the British camp before falling back and forming a line. The battle was decided in favour of the French when the reserve squadrons entered the fray. General Beresford, unhappy with the Portuguese cavalry despite its good performance a month earlier at the Arapiles, requested a reprimand that Wellington did not grant. 11 de agosto de 1812 Photo: Ricardo Ricote Rodri… (CC BY 3.0) What to see and do in Majadahonda
