In August 1948 Frisch visited Breslau/Wrocław to attend an International Peace Congress organized by Jerzy Borejsza . Breslau itself , which had been more than 90 % German speaking as recently as 1945 , was an instructive microcosm of the post-war settlement in central Europe . Poland 's western frontier had moved , and the ethnically German majority in Breslau had escaped or been expelled from the city which now adopted its Polish name as Wrocław . The absented ethnic Germans were being replaced by relocated Polish speakers whose own formerly Polish homes were now included within the newly enlarged Soviet Union . A large number of European intellectuals were invited to the Peace Congress which was presented as part of a wider political reconciliation exercise between east and west . Frisch was not alone in quickly deciding that the congress hosts were simply using the event as an elaborate propaganda exercise , and there was hardly any opportunity for the " international participants " to discuss anything . Frisch left before the event ended and headed for Warsaw , notebook in hand , to collect and record his own impressions of what was happening . Nevertheless , when he returned home the resolutely conservative NZZ concluded that by visiting Poland Frisch had simply confirmed his status as a Communist sympathizer , and not for the first time refused to print his rebuttal of their simplistic conclusions . Frisch now served notice on his old newspaper that their collaboration was at an end
