When the Armia Krajowa began the Warsaw Uprising on 1 August 1944, Dirlewanger was sent into action as part of the Kampfgruppe formation led by SS-Gruppenführer Heinz Reinefarth; once again serving alongside Bronislav Kaminski's militia (now named SS Sturmbrigade RONA).[14] Acting on orders that came directly from Reichsführer-SS Heinrich Himmler, Kaminski's and Dirlewanger's men were given a free hand to rape, loot, torture and butcher.[15]
