The letter caused a reaction in the West.
The Times published a letter criticizing the authorities of the Polish People's Republic, signed by 21 British writers and artists, including
Arthur Koestler and
Alan Bullock. In addition, 15 Italian intellectuals including
Alberto Moravia and 13
Harvard professors defended the signatories. The letter caused the harassment and repression of its signatories and
Tygodnik Powszechny by the authorities. Wańkowicz, was the most severely repressed, being arrested and accused of preparing and forwarding a text containing "false information slandering People's Poland". The writer was convicted and sentenced to three years in prison. However, the Communist authorities, wanting to avoid criticism, did not carry out the sentence, initially , and later the ruling was formally suspended. From 34 signatories of the Letter Konrad Górski withdrew his signature, after which he wrote a letter to Prime Minister Cyrankiewicz, in which he blamed Turowicz for drawing him into the matter. This letter was read by
Zenon Kliszko at a meeting of the
Writers' Union. Ten of the signatories of Letter 34 then signed another letter addressed to
The Times, stating that Letter 34 was to be internal and they criticized
Radio Free Europe. The letter was signed by:
Aleksander Gieysztor, Konrad Górski,
Leopold Infeld,
Julian Krzyżanowski, Kazimierz Kumaniecki,
Edward Lipiński,
Wacław Sierpiński,
Jan Szczepański,
Władysław Tatarkiewicz and
Kazimierz Wyka. Despite this, Polish intellectuals were supported by intellectuals from other countries and letters of support were published in the Italian
Il Mondo and the French
Le Figaro Littéraire. 13 Harvard professors signed a letter to the ambassador of the Polish People's Republic, and
Berkeley professors did the same. == Bibliography ==
