Cao Kun
In April, and in order to appease the Zhili clique, the Guominjun released the deposed ex-president Cao Kun, who had been put under arrest by Feng in 1923. Wu did not respond. The Young Marshal, Zhang Xueliang, had his army occupy the capital, with Wu's troops arriving a little later. They sacked the capital, causing much chaos and leading to the collapse of much of the Beiyang government's bureaucracy. It would not fully recover until its occupation by the Nationalists in 1928.
