In territories annexed from Poland (the Kresy territories and the Białystok Voivodeship), the initial wave of repression of 1939 was rationalized as removal of "social enemies", or "enemies of the people": military, police and administrative personnel, large landowners, industrialists, and merchants. They were usually sentenced to 8–20 years of labor camps. In addition, settlers, or osadniks, as well as foresters and railroad workers were forcibly removed. Massive deportations of the Polish population into remote areas of the Soviet Union took place in 1940–1941. Estimates of the total number of deported Poles vary between 400,000 and 1.9 million people, including prisoners of war.
