With the passing years , Kambanellis 's work remained in manuscript form at his home . Subsequent world events , such as the assassination of US President Kennedy , caused Kambanellis to re-examine and update his manuscript . He then wrote two new chapters , which were eventually published in the Sunday editions of the Greek newspaper '' Eleftheria '' and caused a sensation . In December 1965 , Kambanellis published his book '' Mauthausen '' with the '' Themelio '' publishers in Athens
