Alexander Kolchak
After a military coup d'état in November 1918, when Adm. Alexander Kolchak proclaimed himself the Supreme Ruler of Russia, Boldyrev was forced to emigrate. In December 1918 Kolchak dissolved the old Siberian Army and created a new one on the base of the Ekaterinburg Group (included the 1st and 3rd Corps of the Siberian Army and some other troops) with Radola Gajda as its commander. Three other independent forces were created.
