Jewish Military Union
In any way, it is probable that Paweł Frenkiel personally commanded one of the armed companies of armed fighters during the ill-fated 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. According to some other sources he was killed on 19 June 1943 in Grzybowska Street in Warsaw.
