ld declare itself moral while its merchants profited from the legal sale in China of a drug that was banned in Britain. He wrote: "Your Majesty has not before been thus officially notified, and you may plead ignorance of the severity of our laws, but I now give my assurance that we mean to cut this harmful drug forever." The letter never reached the Queen, with one source suggesting that it was lost in transit. Lin pledged that nothing would divert him from his mission, "If the traffic in opium were not stopped a few decades from now we shall not only be without soldiers to resist the enemy, but also in want of silver to provide an army." Lin banned the sale of opium and demanded that all supplies of the drug be surrendered to the Chinese authorities. He also closed the Pearl River Channel, trapping British traders in Canton. As well as seizing opium stockpiles in warehouses and the thirteen factories, Chinese troops boarded British ships in the Pearl River and South China Sea before destroying the opium on board.
The British Superintendent of Trade in China, Charles Elliot, protested the decision to forcibly seize the opium stockpiles. He ordered all ships carrying opium to flee and prepare for battle. Lin responded by besieging the foreign dealers in the foreign quarter of Canton, and kept them from communicating with their ships in port. To defuse the situation, Elliot convinced the British traders to cooperate with Chinese authorities and hand over their opium stockpiles with the promise of eventual compensation for their losses by the British government. While this amounted to a tacit acknowledgment that the British government did not disapprove of the trade, it also placed a huge liability on the exchequer. This promise, and the inability of the British government to pay it without causing a political storm, was used as an important casus belli for the subsequent British attack. During April and May 1839, British and American dealers surrendered 20,283 chests and 200 sacks of opium. The stockpile was publicly destroyed on the beach outside Canton.
After the opium was surrendered, trade was restarted on the strict condition that no more opium be shipped into China. Looking for a way to effectively police foreign trade and purge corruption, Lin and his advisers decided to reform the existing bond system. Under this system, a foreign captain and the Cohong merchant who had purchased the goods off of his ship swore that the vessel carried no illegal goods. Upon examining the records of the port, Lin was infuriated to find that in the 20 years since opium had been declared illegal, not a single infraction had been reported. As a consequence, Lin demanded that all foreign merchants and Qing officials sign a new bond promising not to deal in opium under penalty of death. The British government opposed their signing of the bond, feeling that it violated the principle of free trade, but some merchants who did not trade in opium (such as Olyphant & Co.) were willing to sign against Elliot's orders. Trade in regular goods continued unabated, and the scarcity of opium caused by the seizure of the foreign warehouses caused the black market to flourish. Some newly arrived merchant ships were able to learn of the ban on opium before they entered the Pearl River estuary, and so they unloaded their cargoes at Lintin Island. The opportunity caused by the sharp rise in the price of opium was seized upon by some of the Cohong trading houses and smugglers, who were able to evade commissioner Lin's efforts and smuggled more opium into China. Superintendent Elliot was aware of the smugglers' activities on Lintin and was under orders to stop them, but feared that any action by the Royal Navy could spark a war and withheld his ships.
In early July 1839 a group of British merchant sailors in Kowloon became intoxicated after consuming rice liqueur. Two of the sailors became agitated with and beat to death Lin Weixi, a villager from nearby Tsim Sha Tsui. Superintendent Elliot ordered the arrest of the two men, and paid compensation to Lin's f
