First Opium War
Pearl River campaign

With the Pearl River cleared of Chinese defences, the British debated advancing on Guangzhou. Although the truce had ended on 6 March, Superintendent Elliot believed that the British should negotiate with the Qing authorities from their current position of strength rather than risk a battle in Guangzhou. The Qing army made no aggressive moves against the British and instead began to fortify the city. Chinese military engineers began to establish a number of mud earthworks on the riverbank, sank junks to create blockships on the river, and started constructing fire rafts and gunboats. Chinese merchants were ordered to remove all of the silk and tea from Guangzhou to impede trade, and the local populace was barred from selling food to the British ships on the river. On 16 March a British ship approaching a Chinese fort under a flag of truce was fired upon, leading to the British setting the fort on fire with rockets. These actions convinced Elliot that the Chinese were preparing to fight, and following the return of the ships of the Broadway expedition to the fleet, the British attacked Guangzhou on 18 March, taking the Thirteen Factories with very few casualties and raising the Union Jack above the British factory. The city was partially occupied by the British and trade was reopened after negotiation with the Cohong merchants. After several days of further military successes, British forces commanded the high ground around Guangzhou. Another truce was declared on 20 March. Against the advice of some of his captains, Elliot withdrew most of the Royal Navy warships downriver to the Bocca Tigris.
