The executioners of the Einsatzgruppen death squads and members of the local Volksdeutscher Selbstschutz, the German-minority militia, justified their actions by falsely stating that the purpose of their police-work was to remove politically dangerous people from Polish society.

[4] The Intelligenzaktion was a major step towards the implementation of Sonderaktion Tannenberg (Special Operation Tannenberg), the installation of Nazi policemen and functionaries — from the SiPo (composed of Kripo and Gestapo members), and members of the SD — to manage the occupation and facilitate the realization of Generalplan Ost, the German colonization of Poland.

[5] The Intelligenzaktion occurred soon after the German invasion of Poland (1 September 1939), and lasted from the autumn of 1939 until the spring of 1940; the mass murder of the Polish intellectuals continued with the operations of the AB-Aktion.

The Einsatzgruppen and the Volksdeutscher Selbstschutz, the Ethnic Self-defence militia of the German minority in Poland, were to kill the intelligentsia identified in the Special Prosecution Book–Poland.

[13] Aware they would be killing unarmed civilians, the commanders of the paramilitary militias strengthened morale with ideological and racialist instructions to the soldier–policemen, that their political role in the ethnic cleansing of Poland (executions, counterinsurgency, policing) would be more difficult than fighting in battle against soldiers; as noted by Martin Bormann, in a meeting (2 October 1940) between Hitler and Hans Frank:[14] The Führer must emphasize, once again, that for Poles there is only one master, and he is a German; there can be no two masters, beside each other, and there is no consent to such, hence, all representatives of the Polish intelligentsia are to be killed.
