大沽口炮台
The British and French sent a squadron of gunboats, under Rear-Admiral Admiral Michael Seymour, to attack China's Taku Forts. The battle ended as an allied success. However, the first phase of the Second Opium War would end with the Treaties of Tianjin and the forts were returned to the hands of the Qing Army, leading to the Second Battle of Taku Forts in 1859.
