Reichsführer-SS, Chief of German Police, Reich Commissar for the Consolidation of German Nationhood, Reich Minister of the Interior, Commander of the Replacement Army, and Commander-in-Chief of Army Group Vistula—Heinrich Himmler ultimately combined all of these positions in his person. All of his roles are described and explained in detail for the first time in this comprehensive book. What were the tasks of the Security Police compared to the SD (Security Service)? What was the function of the Dienststelle SS-Obergruppenführer Heißmeyer? These and other questions are answered in this book, which also describes combat operations by the Waffen-SS and the Ordnungspolizei. The resettlement of the ethnic Germans and the deportation of the Jewish populations of Europe also form part of the book, as do the detailed history of Army Group Vistula. A total of 275 illustrations, together with the complete texts of several of Himmler’s speeches complete this outstanding book about the man responsible for the implementation of National-Socialist policy.
