Second Opium War [SEP] British attacks
Although the British were delayed by the Indian Rebellion of 1857, they followed up the "Arrow" Incident in 1856 and attacked Guangzhou from the Pearl River. Viceroy Ye Mingchen ordered all Chinese soldiers manning the forts not to resist the British incursion. After taking the fort near Guangzhou with little effort, the British Army attacked Guangzhou. Meanwhile, in Hong Kong, there was a possible attempt to poison John Bowring and his family in January, known as the Esing Bakery incident. However, if it was deliberate, the baker who had been charged with lacing bread with arsenic bungled the attempt by putting an excess of the poison into the dough, such that his victims vomited sufficient quantities of the poison that they had only a non-lethal dose left in their system.
