The Battle of Ningpo was fought between British and Chinese Manchu forces in Ningpo (Ningbo), Zhejiang province, China, on 10March 1842 during the First Opium War (1839–1842). After the British captured Chinhai (Zhenhai) on 10October 1841, three days later they captured the nearby city of Ningpo unopposed. On 10March, the Chinese dispatched Manchu Prince Yijing to muster forces and recapture the city but the British repelled their attack. The Chinese forces consisted of ManchuBannermen. Tricked into thinking the British had abandoned the city, the Chinese rushed in only to find mines laid in the streets. The Chinese retreated but were ambushed by the British, and were repelled from the city.
