Since it's Memorial Day today when armed forces are honored and Nigel Cooney is said to be buried in the Klagenfurn War Cemetery, let me share this information:
Cemetery notes and/or description:
Klagenfurt, the only Commonwealth war cemetery in Austria, was begun in June 1945 by the British occupying forces, who moved graves into it from all over the country. Austria was annexed by Germany in March 1938, and many labour, prisoner-of-war and concentration camps were established there by the Germans. The principal POW camps were at Dollerscheim, Gneizendorf, Kaisersteinbruch, Leinz Drau, Spittal Drau, and Wolfsburg Gratz. Commonwealth war dead buried in Austria were mainly servicemen who died in these camps in captivity, airmen who were shot down or crashed while flying over the country and those who died while serving with the army of occupation after the war.
Klagenfurt now contains 589 Commonwealth burials of the Second World War. Between 1950 and 1954, eight First World War graves (three of them unidentified) were moved into the cemetery from small cemeteries at Innsbruck, Mauthausen, Muhldorf, and Vienna. At the same time, special memorials were erected to two other First World War casualties whose graves at Muhldorf and Vienna could not be found.
