Simultaneously steps were undertaken to eliminate 'foreign elements' in Ukraine. OUN-B posters and leaflets incited the Ukrainian population to murder Poles and 'Juedo-Muscovites'. Since the majority of Jews in German-occupied Ukraine had already perished at the hands of Nazis, the OUN-B concentrated its assault on Poles. In Februrary 1943, taking into account the possibility of Germany's defeat, the third conference of the OUN-B finalized its plans.
In the late winter and early spring of 1943 the assault on Polish settlements began. Backed by a peasant self-defence units, the OUNB detachments attacked Polish villages at night or in the early morning, butchering all inhabitants regardless of the sex or age. Bullets were often spared in favour of axes, knives and pitchforks. After the killings were completed, Polish house were looted and set on fire.
