Germany was headed, he never registered complaints about murdering Jews. He did, however, express misgivings about the barbarity and sadism being meted out by the Romanian units that accompanied the Einsatzgruppen in their murderous tasks, since they were not only leaving a trail of corpses in their wake, they were also pillaging and raping in the process. Ohlendorf also lodged a complaint about the Romanian forces, who drove thousands of frail elderly persons and children from Bessarabia and Bokovina—all incapable of work—into German-held regions, which his men forced back into Romanian territory but not without killing a significant percentage of them as a result. Ohlendorf devoted only four years (1939–1943) of full-time activity to the RSHA, for in 1943, in addition to his other jobs, he became a deputy director general in the Reich Ministry of economic affairs. Sometime in November 1944, he was promoted to Gruppenführer. Believing their expertise invaluable, Ohlendorf, Ludwig Erhard, and other experts concerned themselves with how to stabilize German currency after the war. Hoping to salvage the reputation of the SD, Ohlendorf offered his services in the hopes that he could shape the postwar reconstruction of Germany, but along "National Socialist lines", remaining convinced as was Admiral Karl Dönitz (who gave Ohlendorf the economics portfolio), that some form of Nazism would ultimately survive. In May 1945, Ohlendorf participated in Himmler's flight from Flensburg. He and several other subordinates were arrested by the British near Lüneburg on 23 May 1945. Himmler committed suicide shortly after being captured. For several weeks after his arrest, Ohlendorf was carefully interrogated, during which he revealed the criminal nature of the German campaign in the East. Nuremberg trials Ohlendorf was called as a witness by the prosecution during the International Military Tribunal at Nuremberg on 3 January 1946. During the subsequent Einsatzgruppen trial, Ohlendorf was the chief defendant, and was also a key witness in the prosecution of other indicted war criminals. Ohlendorf's apparently reliable testimony was attributed to his distaste for the corruption in Nazi Germany and a stubborn commitment to duty. The court examined Ohlendorf concerning Einsatzgruppen operations in particular. During the trial, Ohlendorf insisted that he, as a loyal Nazi, had acted properly and had done nothing wrong. He expressed no remorse for his actions, telling prosecutor Ben Ferencz that the Jews of America would suffer for what the prosecutor had done, and seemed to have been more
