Miła 18 Ulica Miła 18 ( or 18 Pleasant Street in English ) was the headquarters bunker ( actually a shelter ) of the Jewish Combat Organization ( ŻOB ) , a Jewish resistance group in the Warsaw Ghetto in Poland during World War II . The bunker at Miła 18 was constructed by a group of underworld smugglers in 1943 . The ŻOB fighters arrived there after their own bunker , at 29 Miła Street , had been discovered . The smugglers who had built it were helping the ŻOB as guides . On 8 May 1943 , three weeks after the start of the Warsaw Ghetto Uprising , when the bunker was attacked by the Nazis , there were around 300 people inside . The smugglers surrendered , but the ŻOB command , including Mordechaj Anielewicz , the leader of the uprising , stood firm . German and Ukrainian troops threw tear gas into the shelter to force the occupants out . Anielewicz , his girlfriend Mira Fuchrer and many of his staff committed mass suicide rather than surrender , though a few fighters managed to get out of a rear exit , and later fled from the ghetto through the canals to the Aryan side at Prosta Street on May 10 . The bodies of Jewish fighters were not exhumed after 1945 and the place gained a status of war memorial . In 1946 monument known as " Anielewicz Mound " , made of the rubble of Miła houses , was erected . A commemorative stone with the inscription in Polish and Yiddish was placed on top of the mound . In 2006 a new obelisk designed by Hanna Szmalenberg and Marek Moderau was added to the memorial . The inscription in Polish , English and Yiddish reads : " Grave of the fighters of the Warsaw Ghetto Uprising built from the rubble of Miła Street , one of the liveliest streets of pre - war Jewish Warsaw . " " These ruins of the bunker at 18 Miła Street are the place of rest of the commanders and fighters of the Jewish Combat Organization , as well as some civilians . Among them lies Mordechaj Anielewicz , the Commander in Chief . " " On May 8 , 1943 , surrounded by the Nazis after three weeks of struggle , many perished or took their own lives , refusing to perish at the hands of their enemies . " " There were several hundred bunkers built in the Ghetto . Found and destroyed by the Nazis , they became graves . They could not save those who sought refuge inside them , yet they remain everlasting symbols of the Warsaw Jews ’ will to live . The bunker at Miła Street was the largest in the ghetto . It is the place of rest of over one hundred fighters , only some of whom are known by name . " " Here they rest , buried as they fell , to remind us that the whole earth is their grave . " The names of 51 Jewish fighters whose identities have been established by historians are engraved on the front of the obelisk . Although it is often claimed that Miła 18 was the last shelter in the Ghetto to fall , this was not the case ( according to Jürgen Stroop , his men took 30 " bunkers " on 12 May alone ) . It should be also noted that the current street numbering in Mila Street does not correspond to the wartime numbering : the memorial is nowadays at the intersection of Miła and Dubois streets while the current Miła 18 is an apartment block around 700 metres to the west .
