The Battle of Salamanca took place on 22 July 1812. An Anglo-Portuguese army under the Earl of Wellington defeated Marshal Auguste Marmont's French forces at Arapiles, south of Salamanca, Spain, during the Peninsular War. A Spanish division was also present but took no part in the battle.
The battle involved a succession of flanking manoeuvres in oblique order, initiated by the British heavy cavalry brigade and Pakenham's 3rd Division and continued by the cavalry and the 4th, 5th and 6th divisions. These attacks resulted in a rout of the French left wing. Marmont and his deputy commander, General Bonet, received shrapnel wounds in the first few minutes of firing. Confusion amongst the French command may have been decisive in creating an opportunity, which Wellington seized.
