Verbrennungskommando Warschau

Verbrennungskommando Warschau (German: Warsaw burning detachment) was a slave labour unit formed by the SS following the Wola massacre of around 40,000 to 50,000 Polish civilians by the Germans in the early days of the Warsaw Uprising of 1944. The purpose of the Verbrennungskommando was to remove evidence of the citywide campaign of mass murder that took place during the Uprising, by collecting corpses into large piles and burning them in open-air pyres on Elektoralna and Chłodna Streets among others.
