Ludwik was deported to Germany as a forced laborer and 
          stayed there since September 1941 until March 1945. His documents 
          mention the town of Kassel in Muecke Bezirk in Hessen (http://en.wikipedia.org/wiki/Kassel). 
          The details are not known. A sub-camp of the Dachau Concentration Camp 
          was located in this area during WW-II. The Henschel armament factories 
          were also located in the area, where slave labour from the 
          concentration camp was extensively employed.
          
          We are not sure, if Ludwik was a camp prisoner and worked in these 
          factories since his documents gathered by the IPN (Institute for 
          National Remembrance) and FNPN (Foundation for German-Polish 
          Reconciliation) mention only a sawmill ("Tartak") as a place of his 
          work in Kassel.
