The Battle of Wusong (Woosung) (Chinese: 吳淞戰役) was fought between British and Chinese forces at the entrance of the Wusong River (present-day Huangpu River), Jiangsu province, China, on 16 June 1842, during the First Opium War. The British capture of the towns of Woosung (now Wusong) and Baoshan opened the way to Shanghai, which was captured with little resistance on 19 June.
