№.29 British Encampment on Irgao-Shan, Chusan 舟山英軍營地
In the First Opium War, shortly after the first Battle of Dinghai on July 5-6, 1840, British forces first occupied Dinghai County (now Zhoushan Island). It wasn’t until seven months later, on February 24, 1841, that the British forces completely withdrew from Dinghai County.
