Ratification of the treaty in the following year led to a resumption of hostilities. In 1860, with Anglo-French forces marching on Beijing, the emperor and his court fled the capital for the imperial hunting lodge at Rehe. Once in Beijing, the Anglo-French forces looted the Old Summer Palace and, in an act of revenge for the arrest of several Englishmen, burnt it to the ground. Prince Gong, a younger half-brother of the emperor, who had been left as his brother's proxy in the capital, was forced to sign the Convention of Beijing. The humiliated emperor died the following year at Rehe.
