Alexander Srb: A Serbian officer in the Russian service

The paper is devoted to the strokes of the biography of the Serbian Army Colonel A. Srb, which is incorporated into the key events of the political history of Serbia and Russia at the beginning of the 20th century, and he himself was not just a participant in them, but also had some influence on them. A participant in the 1903 Coup and all the vicissitudes of the Serbian politics at the beginning of the 20th century, an active member of the organization "Unification or Death", who arrived in 1916 with Fr. Corfu to Russia to recruit the Serbian Volunteer Corps, became a witness and participant in the difficult events of 1917. The study of his biography, replete with white spots, allows a deeper understanding of the context of the seething political life that took place both in Serbia and Russia.
