In September a Provisional Eastern-Transbaikal Assembly was organized, and Semyonov transferred to it the civil powers. At the same time military forces of the Far Eastern Republic, masked as independent groups of partisans, began to move to Chita; on September 15, an assembly of workers of the Eastern Transbaikal Region in Nerchinsk proclaimed the creation of the regional Revolution committee. On October 15, Japanese troops left Chita, and the Reds demanded the capitulation of the Whites' garrison.
