The Broadway expedition was a British military expedition that explored the Broadway River (present-day Xi River) in Guangdong province, China, on 1315 March 1841 during the First Opium War. The river was also called the "Inner Passage" or "Macao Passage" as it served as an intricate channel from the Portuguese colony of Macao to the Chinese city of Canton (Guangzhou). The expedition was the first time a European vessel traversed the passage, and was believed by the Chinese to be inaccessible to foreigners due to the shallowness and intricacy of the channel as well as the forts along the banks. The iron steamship "Nemesis" had a shallow draught of 6 ft , which was a major advantage in navigating the river. Despite being over 600 tons burden, the ship was able to navigate through a river that frequently had less than 6 feet of water and through mud in areas of only 5 ft .
