History
Aussenkommando Kattowitz was small subcamp of Auschwitz formed in January 1944.
About ten prisoners spent almost a year building a barracks and an air-raid shelter for the Gestapo in Katowice then known by its German name Kattowitz. Prisoners slept initially in the rooms in the cellar of the Gestapo headquarters. After three weeks they were moved to a shed of the local brickworks.
Dissolution & Liberation
On 31 January to 1 February 1945, prisoners were evacuated along with 50 Gestapo members by truck to Klodzko. From there they were deported on a rail transport to Ölsnitz.
