Where can I check up on the feelings of World War 2 survivors on being upset at no Moshiach? [closed]

I am interested in reading up on the reactions of the Jewish war survivors at liberation in the concentration camps. My grandmother told me that the frum Yidden were devastated that it was the Russians who came to free them, they had assumed the whole time during the war that Moshiach is definitely going to come and save them. Then, when it was the plain Goyim who liberated them, they couldn't believe that Moshiach had not come and this fact depressed many.

Are there any documented war survivor memos on this? Can anyone add anything?

A good place to start, would be the sentiments discussed by Rebbetzin Esther Farbstein, in her monumental work, “B’seiser Ra’am” [also published in English as “Hidden in Thunder: Perspectives on Faith, Halachah, and Leadership during the Holocaust”] (Hebrew edition. 5765, p. 470-471).

She describes the phenomenon of many formerly religious people who tenaciously clung to their faith during the terrible war years, and who hoped to return to their father’s was as soon as they would be able to, only to abandon faith after their liberation. The main reason for this was the deep disappointment they felt with the world they found after war, which was so different from the new “world to be” that they had envisioned during the war.

While they were in the concentration camps, they believed that that there was some form of explanation to their suffering. Perhaps these were the “chevlei Moshiach”, the “birth pangs” which serve to usher in the coming of the Moshiach.

Their ensuing disappointment was tough. The long waited for redemption did not come, and the world was alien to them. The depression in the DP camps reigned, and the faith was weakened.

She quotes R’ Yehoshua Moshe Ahronson, a noted posek, and holocaust survivor (translated here in part): “…Our greatest hope was the coming of Moshiach. We couldn’t believe that anything less was going to happen (Alei Meroros, p. 304)”.

“We hoped to see, not the American army, rather the holy tribes, the 12 sons of Yaakov”, was part of the Klauzenberger Rebbe’s first Friday night speech after liberation (Lapid Aish, p. 258, cited in B’seiser Ra’am at note 29).

Then follows a lengthy quote from “Kol Hakassuv LeChaim” (p. 92), by R’ Chaim Alter Roth (translated here in part):

“The test to remain glued to faith in Hashem after liberation, was more difficult experience during the destruction itself ... In the camps, our hearts pulsed with the great hope that tomorrow we would be redeemed. As my father used to say, “Moshiach will come to Auschwitz”. We thought would suddenly there would be the sudden revelation [of Moshiach] and the redemption, and we would see with our own eyes why we suffered. We would understand what is the reason and purpose of all this agony.

“But the most difficult was the day of liberation. They called it "liberation", but I don’t know what kind of “liberation” this was. To the contrary, we discovered the destruction around us, and along with it we saw that nothing had changed.

“The world went on as usual, and Hashem’s face remained hidden, just as in the past. We found no change in the world... Jews, liberated from the death camps, rolled about in barracks, while the German murderers lived in neat homes. Murders and pogroms took place in many places, and Jewish refugees migrated from land to land. They were forced to illegally cross borders, and no country was willing to accept them etc.

["In face of all the this, many Jews who had held up and withstood many tests, to our dismay, lost the faith, and lacked the strength to continue"].

Not answering your question but listen to this.

My Grandmother told me that after she was liberated from Auchwitz she met her uncle. Her Uncle was the most Medakdek in Halacha that you could get. She saw him getting into a bus on Shabbos. He called out to her and said, come and join and we will build new lives somewhere. When my Grandmother replied that it was Shabbos, he answered, if He would have left me even one member of my family alive, then it would still be Shabbos. With that he left.

Many years later, my Grandmother wanted to meet him and he never let. He said, better remember me as a Frum Yid.

This shows you that those who went off lived bitter lives afterwards regretting leaving their faith. However, the anger there was at the time was too powerful for some.
