These squads were recruited from Heydrich's Sicherheitsdienst (hence, SD). They already knew their mandate was broad. Their supreme leader had six weeks ago told General Keitel that "in the Government General of Poland there will have to be a tough struggle for national existence which will permit of no legal restraints." In the lofty rhetoric of their leaders, as the Einsatz soldiers knew, a struggle for national existence meant racial warfare, just as Einsatz itself, Special Chivalrous Duty, meant the hot barrel of a gun.Thomas Keneally
