The allied army subsequently took Salamanca on 17 June, just as Marshal Marmont approached. The two forces met on 22 July, after weeks of maneuver, when Wellington soundly defeated the French at the Battle of Salamanca, during which Marmont was wounded. The battle established Wellington as an offensive general and it was said that he "defeated an army of 40,000 men in 40 minutes." The Battle of Salamanca was a damaging defeat for the French in Spain, and while they regrouped, Anglo-Portuguese forces moved on Madrid, which surrendered on 14 August. 20,000 muskets, 180 cannon and two French Imperial Eagles were captured.
