The German camp command entrusted him with interpreter work in connection with the initial Jewish
resistant against the British military. Henceforth, he translated British orders into Yiddish.
Unknown to the British or Germans, he added words making it clear to the refugees which orders
were not to be followed. When the Exodus Passengers arrived and were required to give their name,
date of birth and nationality, Benjamin Gruszka translated:
Yeder Yid zoll zich farschreiben mit linke Nehmen. (Every Jew should give a false name).
The people understood and followed his instructions, resulting in the following:
My name is Marlene Dietrich and I come from Erez Israel.
I am Lord Montgomery and come from Tel Aviv.
Initially, the German personnel carefully wrote down the names and then hesitated and asked, "Really?"
When Lord Pickenham, minister for the British Zone in Germany, visited the Pöppendorf camp and required the Jews to register, Bolek translated. To Lord Pickenham's speech he added the Yiddish proverb: "A loi mit n Alef", which amounts to:
A nothing with an A in front, or He can make long speeches.
To which the majority answered "Amen". Lord Pickenham asked Bolek what this meant, to which he replied: "The Jews thank you for your warm speech".
The Haganah commander knew that there could be no trouble-free aid without dialogue with the camp
administration, and so the protest against the German camp personnel was terminated. The Haganah
commanders also decided to withdraw from their function as leaders, and to build a Jewish camp
The election of an independent Jewish camp committee had been promoted by the German camp administration before the Jews had arrived in Lübeck, "so as to eliminate all possibility of friction within the camp between the German personnel and the Jews".
The election took place on 15th September 1947. Under the chairmanship of Mordechai Rosmann, the Jewish committee assumed the role of representing the camp inhabitants, and became the Jewish contact with the British camp administration and German camp personnel. It continued to organize further daily protests against British government policy.
