According to Peter Longerich, Dirlewanger's leadership "was characterized by continued alcohol abuse, looting, sadistic atrocities, rape, and murder—and his mentor Berger tolerated this behaviour, as did Himmler, who so urgently needed men such as the Sonderkommando Dirlewanger in his fight against 'subhumanity'." In his letter to Himmler, SS-Brigadeführer Odilo Globocnik recommended Dirlewanger, who "in charge of the Jewish camp of Dzikow ... was an excellent leader." During the Nuremberg Trials after the war, Berger said: "Now Dr. Dirlewanger was hardly a good boy. You can't say that. But he was a good soldier, and he had one big mistake that he didn't know when to stop drinking."
