Sporrenberg was transferred to the command of SS-
Oberabschnitt Rhein in
Wiesbaden on 25 September 1939 and, on 1 October, concurrently was named the
Higher SS and Police Leader (HSSPF) Rhein. With this appointment came a seat on the Defense Committee of
Wehrkreis XII. On 30 January 1940, he was promoted to the rank of SS-
Gruppenführer and, in June 1940, he became a member of the
Waffen-SS. He returned to Königsberg in that month as commander of SS-
Oberabschnitt Nordöst and the HSSPF
Nordöst, remaining in that assignment until 1 May 1941. He also sat on the Defense Committee for
Wehrkreis I and was the representative of the
Reich Commissioner for the Consolidation of German Nationhood for that military district. He then underwent training in the main office of the
Ordnungspolizei and at the
Reich Security Main Office (RSHA) through June. From 21 July to 14 August 1941, he was
SS and Police Leader (SSPF) in the
Generalbezirk Weißruthenien, headquartered in
Minsk. He then served on the staff of
Reichskommissar Erich Koch in the
Reichskommissariat Ukraine. In March 1943, he was assigned to the staff of SS-
Obergruppenführer Erich von dem Bach-Zelewski to combat
partisans in the
Bandenbekämpfung operations. Sporrenberg was made a
Generalleutnant of police on 7 July 1943 and succeeded
Odilo Globočnik as SSPF of Lublin in the
General Government of occupied
Poland from 16 August 1943 to 25 November 1944. In this capacity, Sporrenberg oversaw and implemented the mass shooting of Jewish
forced laborers during
Operation Harvest Festival on 3–4 November 1943 that resulted in the murder of an estimated 40,000 to 43,000 individuals. In November 1944, Sporrenberg and several of his staff were redeployed to Norway. There Sporrenberg served as SSPF of the newly established command of
Süd-Norwegen (South Norway). He was the only holder of this post and remained there until Germany's surrender. == Post-war ==
