Battle context

The Battle of Chapoo was fought on the northern shore of Hangzhou Bay during the First Opium War, pitting a British force of approximately 2,220 against a Qing defense estimated at 8,000–10,000 troops. Qing casualties of 1,200–1,500 against the smaller British force indicate a severe disparity in battlefield outcomes, consistent with the pattern of British operational advances along China's coast during the 1842 campaign season that ultimately led to the war's conclusion.
