The situation had changed when on July…
August 1841 CE
Pottinger wants to negotiate terms with the Qing for the entire country of China, rather than just the Pearl River, so he turns away Chinese envoys from Canton and gives permission for the expeditionary force to proceed with its war plans.
Admiral Sir William Parker had also arrived in Hong Kong to replace Humphrey Fleming Senhouse (who had died of a fever on June 29) as the commander of the British naval forces in China.
It wis agreed by the British commanders that combat operations should be moved north to put pressure on Peking, and on August 21 the fleet sails for Amoy.
