== Ukrainian-Soviet War ==
In the Autumn of 1917, Tiutiunnyk organized a unit of "[[Free Cossacks|Free Kozaks]]" in [[Zvenyhorodka]], and became its leader. After the fall of Kiev to [[Red Army|Bolshevik forces]] in 1918, Tiutiunnyk transformed the unit to a kish-size of 20 thousand and engaged in battles throughout central Ukraine. He had a number of victories over the Bolshevik forces, including winning battles against the [[Bolshevik]]'s and 8,000 group of [[...|Mikhail Muravyov]], while reclaiming the towns and cities like [[Kotovsk, Ukraine|Birzula]] and [[Vapniarka]] from Bolshevik forces. Later, in 1918, Tiutiunnyk's unit waged a guerilla warfare against both the occupying German forces and the forces of the new [[Ukrainian State|Hetmanate]].ref
