While in Eretz Yisrael, the plan to resist a possible Nazi invasion was compared to
Masada, to
Tobruk, and to Musa Dagh. The Jews from the ghettos talked about Musa Dagh more often than they did about Masada. To them, Masada was more a symbol of suicide than a symbol of a battle, while Musa Dagh was a symbol of rebellion.
Haika Grossman, who in her youth was a
partisan and a participant in the
ghetto uprisings in
Poland and
Lithuania, said that
Musa Dagh was popular with Jewish activists in Europe, was read and "passed from hand to hand": According to testimony from the Warsaw Ghetto,
Musa Dagh had a big impact on
Janusz Korczak, a director of an
orphanage for Jewish children. A member of Korczak's staff said that they discussed
Musa Dagh in the summer of 1941 at one of their meetings. In particular they discussed the episode in which a
pastor abandoned the children to save himself (in the book he later came back). During this discussion, Korczak said "that he would not under any circumstances be parted from his children" and he did not. He was offered sanctuary on the "
Aryan side" by
Żegota but turned it down repeatedly, saying that he could not abandon his children. He perished together with the children.
Emmanuel Ringelblum known for his
Notes from the Warsaw Ghetto wrote: What are people reading? This is a subject of general interest; after the war, it will intrigue the world. What, the world will ask, did people think of on Musa Dagh.... One more testimony comes from the
Kladovo-Šabac group: "Like Jews throughout the world, from the ghettos of Eastern Europe to the pioneering settlements of Palestine, the Kladovo refugees (young and old) read
The Forty Days of Musa Dagh by Franz Werfel and became enthralled by the story of Armenia's struggle against Turks during the First World War." A member of the
Dutch underground said about
Musa Dagh: "It was a 'textbook' for us. It opened our eyes and spelled out for us what might happen, although we did not know what in fact would occur." In a 1938 letter written from prison in
Benito Mussolini's
Italy,
Vittorio Foa stated: "In a novel by Franz Werfel,
The Forty Days of Musa Dagh, I found a pretty faithful description of what the treatment of Jews would be in Mitteleuropa". ==Jewish critics of the book==
