Tianshun proved to be a troubled time and Mongol forces within the Ming military structure continued to be problematic. On 7 August 1461, the Chinese general Cao Qin and his Ming troops of Mongol descent staged a coup against the Tianshun Emperor out of fear of being next on his purge-list of those who aided him in the Wresting the Gate Incident. Cao's rebel force managed to set fire to the western and eastern gates of the Imperial City (doused by rain during the battle) and killed several leading ministers before his forces were finally cornered and he was forced to commit suicide.
