had two entirely manned and fully armed companies and two additional en cadre companies, to be manned by newly arrived volunteers when need arises. This indeed happened in April 1943, though the actual number of ŻZW soldiers to take part in the Uprising is a matter of debate. Apart from the fighting groups, the ŻZW was organized into several departments. Political Chair, Dawid Wdowiński Information Department, directed by Leon Rodal; Organization Department, directed by Paweł Frenkel; Supply Department ("Kwatermistrzowski"), directed by Leon Wajnsztok; Finances Department, without a director; Communication Department (contacts with Armia Krajowa mainly), directed by Dawid Apfelbaum; Medical Department led by dr Józef Celmajster (under pseudonym Niemirski); Juridical Department under Dawid Szulman; Rescue (Ratowanie) Department (transporting Jewish children and others outside the ghetto), under Kalma Mendelson; Department of Technology, Transport and Supplies (which, among other things, built two tunnels under the Ghetto walls) led by Hanoch Federbusz; Military Department under Paweł Frenkel and Dawid Apfelbaum. Warsaw Ghetto Uprising During the Warsaw Ghetto Uprising ŻZW is said to have had about 400 well-armed fighters grouped in 11 units.
