[24] In 1860 an Anglo-French expedition led by Lord Elgin occupied Peking after defeating Imperial Chinese forces and forcing the Emperor to flee to Jehol. Every palace, temple and mansion in the capital was thoroughly plundered, and the Imperial Summer Palace burned to the ground. The occasion that provoked this war was the 'Arrow' incident of 1856, when a Chinese-owned but Hong Kong-registered ship, the Arrow, was forcefully boarded by Chinese police at Canton for the alleged purpose of searching out a notorious pirate. Incidentally, Elgin is buried in an old church yard at Dharamsala, the present headquarters of the Dalai Lama in northern India.
