On 2 August 1944, at the time of the liquidation of the Gypsy camp by the Germans, the Roma tried to mount resistance, but their efforts were brutally suppressed. Three months earlier, as a result of a rebellion, the Roma managed to stop the perpetrators. Approximately 23,000 Roma people were imprisoned in Auschwitz-Birkenau, out of which 21 thousand were murdered by the Germans.
