Although one of the most important leaders of the Warsaw Ghetto Uprising and the Jewish resistance in the months preceding April 1943, Frenkiel is also one of the least well known to historians; both his early life and ultimate fate are a subject of some controversy.
[3] Earlier publications and accounts by Tadeusz Bednarczyk,[4] Henryk Iwański and Kałmen Mendelson assert, that Paweł Frenkel was one of the deputies of JMU's commander Dawid Moryc Apfelbaum.
However, other accounts, including those by Dawid Wdowiński[5] and Cezary Szemley, suggest that Frenkiel was indeed the leader of the entire organisation.
[6][7] In either case, it is probable that Frenkiel personally commanded one of the companies of armed fighters during the Warsaw Ghetto Uprising of 1943.
According to a widespread opinion he was killed in action while defending the headquarters of the Jewish Military Union at #7 Muranów Square.
