Under Rear Admiral Michael Seymour, ships on the station were involved in operations arising from the attack on the British coaster "Arrow". During the Second Opium War or "Arrow War," in China, Seymour commanded the Battle of the Bogue in November 1856, helped destroy the Chinese fleet in the Battle of Fatshan Creek in June 1857, captured Canton in December, and in 1858 he captured the forts on the Baihe (Hai River), compelling the Chinese government to consent to the Treaty of Tientsin.
