Second Battle of Porto
The Second Battle of Porto, also known as the Battle of the Douro or the Crossing of the Douro, was a battle in which General Arthur Wellesley's Anglo-Portuguese Army defeated Marshal Nicolas Soult's French troops on 12 May 1809 and took back the city of Porto. After taking command of the British troops in Portugal on 22 April, Wellesley (later named 1st Duke of Wellington) immediately advanced on Porto and made a surprise crossing of the Douro River, approaching Porto where its defences were weak. Soult's late attempts to muster a defence were in vain. The French quickly abandoned the city in a disorderly retreat.
