Young people of the Akiva youth movement, who had undertaken the publication of an underground newsletter, HeHaluc HaLohem ("The Fighting Pioneer"), joined forces with other Zionists to form a local branch of the Jewish Fighting Organization (ŻOB, Polish: Żydowska Organizacja Bojowa), and organize resistance in the ghetto, supported by the Polish underground Armia Krajowa. The group carried out a variety of resistance activities including the bombing of the Cyganeria cafe – a gathering place of Nazi officers. Unlike in Warsaw, their efforts did not lead to a general uprising before the ghetto was liquidated. From 30 May 1942 onward, the Nazis began systematic deportations from the Ghetto to surrounding concentration camps. Thousands of Jews were transported in the succeeding months as part of the Aktion Krakau headed by SS-Oberführer Julian Scherner. Jews were assembled on Zgody Square first and then escorted to the railway station in Prokocim. The first transport consisted of 7,000 people, the second, of additional 4,000 Jews deported to Bełżec death camp on 5 June 1942.
