Chapter 3 discusses the key characteristics and numbers of internees. It argues that here, too, the similarities across the zones were greater than is often assumed, but that important differences emerged. It shows that internee numbers were higher in the western zones than is often believed and that most internees in every zone were middle-aged men. The chapter examines competing claims about internees’ Nazi incrimination and distinguishes between different organizations and tiers of the Nazi Party hierarchy. It shows that there were more lowly than highly ranked personnel in every zone, but that seniority levels were higher in the western (and especially the American and British) zones and that only there were significant numbers of SS members interned. Yet one should not overlook the personnel of the broader Nazi repressive apparatus nor downplay the responsibility of even the lowest-ranked Party officials who were interned in the Soviet zone in large numbers. The chapter also argues that the Soviets interned fewer adolescents, Social Democrats, and members of other postwar political parties than is often believed and that some were targeted for Nazi-era offences. Nevertheless, their number had no equivalent in the west and even more were prosecuted by Soviet Military Tribunals.
