In 1787, Prime Minister William Pitt the Younger and East India Company official Henry Dundas dispatched Colonel Charles Cathcart to serve as Britain's first ambassador to China. Cathcart became ill during the voyage, however, and died just before his ship, HMS "Vestal", reached China. After the failure of the Cathcart Embassy, Macartney proposed that another attempt be made under his friend Sir George Staunton. Dundas, who had become Home Secretary, suggested in 1791 that Macartney himself take up the mission instead. Macartney accepted on the condition that he would be made an earl, and given the authority to choose his companions.
