At length the difficulty reached a climax. Arrests and punishments for the use of opium became common throughout the empire, three royal princes were degraded for this practice, a commissioner with large powers was sent from Peking to Canton, and the foreigners were ordered to deliver up every particle of opium in their store-ships and give bonds to bring no more, on penalty of death. As a result, somewhat more than one thousand chests were tendered to the commissioner, but this was declared to be not enough, and that official at once took the decisive measure of cutting off the food-supply from the foreign settlement. This and other active steps brought about the desired result. Captain Elliot, the British superintendent of commerce, advised a complete delivery of all opium under British control, and before night more than twenty thousand chests of the deleterious drug were surrendered into his hands, and were offered by him to the commissioner the next day. News of this event was sent to Peking, and orders came back that the opium should be all destroyed; which was done effectively by mixing it with salt water and lime in trenches and drawing off the mixture into an adjacent creek. Care was taken that none should be purloined, and one man was executed on the spot for attempting to steal a small portion of the drug. Thus perished an amount of the valuable substance rated at cost price at nearly eleven million dollars. We have described this event at some length, as it led to the first war between China and a foreign power. The destruction of the opium deeply offended the British government, and in the next year (1840) Captain Elliot received an official letter to the effect that war would be declared unless China should pay for the goods destroyed. As China showed no intention of doing so, an English fleet was sent to Chinese waters in the summer of 1841, whose admiral declared a blockade of the port of Canton, and, on July 5, bombarded and captured the town of Ting-hai. Various other places were blockaded, and, as the emperor rejected all demands, the fleet moved upon Canton, taking the forts along the river as it advanced. In the end, when an attack had become imminent, the authorities ransomed their city for the sum of six million dollars.
