The mass murder operations of Intelligenzaktion killed 100,000 Polish people; by way of forced disappearance, the Nazis imprisoned and killed selected citizens of Polish society, identified before the war as enemies of the Reich; they were buried in mass graves at remote places.[4] To facilitate the depopulation of Poland, the Nazis terrorised the general populace with the public, summary executions of selected intellectuals and community leaders, before effecting the expulsions of the general population from occupied Poland. The executioners of the Einsatzgruppen death squads and the local Volksdeutscher Selbstschutz, the German-minority militia, pretended that their police-work was meant to eliminate politically dangerous people from Polish society.[4]
