I found this Web Page.
It explains the life of German POW's being held in the UK during and after World War Two.
This little story catch my eye .....
There is today in England an extraordinary case of Fallschirmjäger Obergefreiter Hans Teske who still remains a PoW to this day! He was taken prisoner in Tunisia in 1943 and imprisoned in Hill Hall Camp (Camp 116) near Epping, Essex and during his time there made several escape attempts. At the war's end he did not want to return to Germany as his home was now in Soviet held territory so the British allowed him to live outside the camp on a 12 monthly parole basis. In June he applied for a transfer to Kent and the officials removed his name from the list in Epping but for some reason did not put his name on their records in Kent. When he discovered the error he asked for his name to be put on the repatriation list but was refused. He continued his protests and lobbied his local Member of Parliament and several German ambassadors but to no avail and in 1970 decided not to pursue the matter so technically he is still a prisoner of war to this day!
Hope you enjoy this site.
