Baron Alexey Budberg commanded in the autumn of 1917 a corps stationed near Dvinsk. In mid-November 1917, leaving command of the corps, he moved to Petrograd. At the end of January 1918 he went to the Far East, where he remained (mostly in Harbin) until the spring of 1919. On March 26, 1919, he was appointed Chief of Supply at the headquarters of Admiral Alexander Kolchak, and at the end of April that same year he went to Omsk, where he stayed in that position—and later in the post of managing the Military Ministry—until October 1919.
