By the end of June 1941
Taras Borovets, with support from German occupation forces officials, decided to create his own military formation. At the beginning of July 1941 he was nominated by the Germans to the post of Ukrainian militia commander at
Sarny district. By the beginning of August 1941 he obtained German permission to create an armed military formation which he named the Polissian Sich. The main tasks of this newly created formation was " by the order of German military command … establishing a self defense against
Bolshevik regular and partisan units." Borovets' military formation obtained high praise from the Germans; they especially noted the cruel massacre of retreating
Soviet Army soldiers which this formation had conducted earlier. At the beginning of August, Borovets made an attempts to obtain military support from the two rival factions of the
Organization of Ukrainian Nationalists.
Stepan Bandera's OUN-B rejected his proposal while the
OUN-M under
Andriy Melnyk faction agreed to provide support. Several military officials affiliated to the OUN-M joined the UPA-Polissian Sich. The Sich's chief of staff was
Petro Smorodsky, formerly a lieutenant colonel of the UNR Army. After defeating a Soviet force at
Olevsk on 21 August, Borovets established his headquarters there. From this time till the middle of November 1941, the Bulba formation controlled a large territory of northwest Ukraine which lay away from central roads. By the autumn of 1941, it had 2,000-3,000 armed personnel and published the official newspaper
Haidamaka. Arms and ammunition were supplied by the Germans with which Borovets maintained friendly relations. In November 1941, the German administration began to disband nationalist military formations, some of which were reformed into Ukrainian auxiliary police under direct German command. On 16 November 1941, UPA/The Polissian Sich was formally demobilized.
Rule in Olevsk By August 1941,
Taras Bulba-Borovets had appointed Petro Smorodskyi as commander of the garrison in
Olevsk and commanded up to 600 men; later, Boris Simonovich followed as the leader of the raion-council. Around 3,000 Jews lived in the Olevsk, which was around 42% of its population. The Jews of Olevsk were subjected to pogroms and were assigned to forced labor tasks, mainly to humiliate them. In addition to the physical abuse, the
Polissian Sich imposed a collective tax of 100,000 rubles on the Jewish population. In November 1941, the rule of the Polissian Sich ended with the taking over of German civil and military administration. Still, the Polissian Sich were integrated in the implementation of German administration, especially in the ghettoization of the Jews. Also around 50 Sich-members and two Sich-commanders participated in liquidations of Jews in mid-November 1941. Additionally on 20 November 1941 Sich-members took part at the liquidations of 535 Jews in the village of Varvarovka, where they were brought from
Olevsk. ==Ukrainian Insurgent Army ==
