#Sonderaktion1005 was a #Nazi operation, June '42 to late '44, to hide evidence of the #Shoah/#Holocaust using specialized prisoner #Sonderkommando, #Leichenkommandos ("corpse units"), to exhume mass graves left by #Einsatzgruppen & #AktionReinhard #DeathCamps & burn the victims.

On #ThisDayInHistory in 1943, a revolt in the #Treblinka #ExterminationCamp led to the escape of 400 prisoners -- half the total there to be gassed. Fewer than 70 survived the war, however. The three #AktionReinhard camps were built for the sole purpose of murdering Polish Jews.
