Chapter 2, “The Killing Years,” explains the two-wave Nazi police genocide against the intelligentsia in 1939–1940, its fallout, and how these initial killing campaigns shaped the Nazi German occupation administration for Poland. German anti-intelligentsia campaigning was bloody but ultimately drove the resistance it attempted to thwart. The first campaign, codenamed Operation Tannenberg, was coordinated with the military campaign in 1939 but delayed in Warsaw because of the siege. Tannenberg went awry and was complicated by the circumstances of the invasion and incoming occupation. After Nazi Germany established a civilian occupation under general governor Hans Frank, Frank revived anti-intelligentsia killing with his new campaign, the Extraordinary Pacification Action (AB-Aktion). This campaign’s violence shocked Poles and provoked the resistance it was intended to achieve. This chapter argues that the two Nazi genocidal campaigns failed but shaped the nature of Nazi occupation administration, and encouraged the first violent Polish resistance in response.
