Wang Chan-yuan, held at Tientsin and Peking, during April and May 1921, General Chang was appointed High Commissioner for Mongolia with full power to reconquer Urga which was then in the hands of Soviet Russians. During the latter part of 1921 General Chang again went to Peking from Manchuria ,to adjust matters to his own satisfaction, and the result of his visit was the installation of the Liang Shih-i Cabinet on December 24, 1921. In March 1922 General Chang was awarded the First Order of Wenfu. During the winter 1921-22, a military and political coalition with General Chang as the leader was organized with the avowed purpose of eliminating Wu Pei-fu. The members of the coalition were the Manchurian military leaders, the Anfu leaders under Tuan Chi-jui, the Chiaotung faction under Liang Shih-i, the Tuchuns of Honan, Anhui and Chekiang, and the Kuomingtang Party in the South under Sun Yat-sen. However this later met with failure as some of the members of the coalition lost their courage. The result of this invasion was a war in the vicinity of Tientsin and Peking. Fighting commenced on April 18, and lasted until May 4, when Chang's troops in the west of Peking had suffered heavy loss at the hands of Feng Yu-hsiang's 11th Division. The evacuation commenced at once and by noon of May 4. Chang's entire force was enroute for Mukden. On May 1, 1922, Presidential Mandates "were issued, dismissing General Chang from the position of Civil and Military governors of Fengtien, abolishing the posts of High Inspecting Commissioner of the Three Eastern Provinces and of the High Commissioner for Mongolia, and ordering him to be dealt with by law. Ever since this defeat Manchuria under General Chang's rule has been independent of Peking with himself as the Commander-in-Chief of the Forces for the Maintenance of Order and Peace in Manchuria. In September 1924 following the outbreak of the war in the lower Yangtse district between Chekiang and Kiangsu provinces, Marshal Chang Tso-lin, mobilized his forces for the purpose of assisting his associate Marshal Lu Yung-hsiang in the Yangtze area. Owing largely to the coup d'etat of General Feng Yu-hsiang, in Peking, Marshal Chang was successful in defeating the leading power purporting the Peking government, having been responsible with General Feng Yu-hsiang in the return of Tuan Chi-jui to the presidency.
