Battle of Woosung

Battle context

The Battle of Wusong was fought at the entrance of the Wusong River in Jiangsu province, where British forces under Hugh Gough and William Parker engaged a Qing garrison of 4,000–5,000 troops commanded by Chen Huacheng. The British capture of Woosung and Baoshan was the decisive operational step that opened the Yangtze River approach to Shanghai. With those river mouth positions taken, Shanghai fell three days later with little resistance, giving British forces control of a major commercial and strategic center during the final phase of the First Opium War. The engagement cost the Qing side 198 casualties and effectively collapsed the forward defensive line protecting the lower Yangtze valley, accelerating the broader British advance that would culminate in the treaty negotiations ending the war.
