Explanation:

In February 1840 the British government decided to launch a military expedition, and Elliot and his cousin, George (later Sir George) Elliot, were appointed joint plenipotentiaries to China (though the latter, in poor health, resigned in November). In June, 16 British warships arrived in Hong Kong and sailed northward to the mouth of the Bei River to press China with their demands. Charles Elliot entered into negotiations with the Chinese, and, although an agreement was reached in January 1841, it was not acceptable to either government. In May 1841 the British attacked the walled city of Guangzhou (Canton) and received a ransom of $6 million, which provoked a counterattack on the part of the Cantonese. This was the beginning of a continuing conflict between the British and the Cantonese.
