Desk perpetrator or crimes against humanity? A Nazi official from Lower Bavaria turns out to be an organizer of Holocaust crimes in Ukraine: After failing as a vocational school teacher, Josef Glück rises to become the NSDAP district leader in Vilshofen and Regen, and in 1936, the mayor of Zwiesel. He skillfully makes himself indispensable alongside the Gau leadership in Bayreuth. As a special envoy of Reich Minister Alfred Rosenberg, Glück arrives in Ukraine in 1942 and participates in the liquidation of the ghetto in Luzk - through mass shootings, 25,000 Jewish men and women are murdered by German police officers. In 1944, Glück moves to Italy and coordinates, as head of the German occupation in the province of Udine, the SS-led deployment of 40,000 Cossacks and Caucasians against partisans in the Carnic Alps. This biography traces buried trails, exposes the unscrupulous maneuvers of a cunning political careerist, brings carefully concealed Nazi violent crimes to light, and gives a voice to forgotten victims - a historically criminal documentation, spurred by the shameful failure of West German post-war justice.
