This article discusses ambiguous tactics of German Communist resisters in the Third Reich. The official historiography of the German Democratic Republic (GDR) portrayed Communist resisters as unfaltering heroes. By contrast, revisionist studies published after 1990 presented Communists as traitors and renegades. This study transcends these approaches that revolve around legitimation or de-legitimation of the dictatorship, and examines the dubious manoeuvring of three German Communists who strategically collaborated with the Nazis, namely Theodor Bottländer, Friedrich Schlotterbeck and Wilhelm Knöchel. While Knöchel's attempts to outwit the Gestapo failed and could not prevent his execution, Schlotterbeck and Bottländer found ways to survive - largely without betraying their comrades. Even so, the Kommunistische Partei Deutschlands (KPD), as well as its successor in the GDR, the Sozialistische Einheitspartei Deutschlands (SED), reprimanded venturesome, inventive and obstinate Communists, excluded them from the party and brought them to court. The harsh reactions are indicative of the inability of Communist historiography to acknowledge ‘Eigen-Sinn’, and highlight a central shortcoming of the antifascist doctrine. Likewise, more recent revisionist approaches have failed to recognise various attempts of Communists to minimise harm and survive in the grey zone between betrayal and loyalty.
