First Opium War

1839–1842

Britain went to war with Qing China after Commissioner Lin Zexu seized and destroyed the British merchants' opium at Canton. The Qing coast was defended by forts and wooden war junks that were no match for British ships of the line and frigates, and the East India Company's iron paddle steamer Nemesis, drawing only five feet of water, took the war up rivers no warship had reached. After the fall of the forts at the Bogue, Amoy, Chinhai and Woosung, a British fleet sailed up the Yangtze to Nanking, and China signed away Hong Kong and opened five ports to foreign trade.
