Li Yuanhong
On 1 July 1917, Zhang officially proclaimed the restoration of Qing dynasty and requested that Li Yuanhong give up his presidency, which Li promptly rejected. Duan Qirui led his army and defeated Zhang Xun's restoration forces in Beijing. One of Duan's airplanes bombed the Forbidden City, in what was possibly the first aerial bombardment in East Asia. On July 12 Zhang's forces disintegrated and Duan returned to Beijing.
