The Red Army took it in February 1918, followed by the Army of the German Empire in March; Ukrainian forces retook the city in December. During February 1919 the Red Army regained control; in August it was taken first by Symon Petlura's men and then by Denikin's army. The Soviets regained control in December 1919. On the eve of Kyiv Offensive Korosten lay on the frontlines between the Polish and Soviet Forces. On 27 February 1921 The Haydamatsky Kish of the Ukrainian People's Republic led by Symon Petliura, a separate Zaporizhzhya detachment led by Konstantin Prisovsky, and a unit of Sich Riflemen led by Yevhen Konovalets passed though Korosten, heading for Kyiv, in an attempt to recapture it from Bolshevik troops.
