The Anielewicz Bunker (Polish: Bunkier Anielewicza), also known as the Anielewicz Mount (Polish: Kopiec Anielewicza) was the headquarters and hidden shelter of the Jewish Combat Organization (ŻOB), a Jewish resistance group in the Warsaw Ghetto in Poland during the Nazi German occupation of World War II.

[1] From 17 April 1943 to 18 May 1943, SS Brigadefuehrer Jürgen Stroop reported to SS-Obergruppenfuehrer and General of Police Krueger that 56,065 of the remaining Jews of the Warsaw ghetto were deported to death camps or exterminated by gunshot, explosion, fire, or asphyxiation.

[3] On 8 May 1943, three weeks after the start of the Warsaw Ghetto Uprising, when the bunker beneath 18 Mila Street was found by the Nazis, there were around 300 people living there.

It is to be forced open tomorrow... On the average the raiding parties shoot 30 to 50 Jews each night... Today we blew up a concrete building which we had not been able to destroy by fire.

[1] The armed resistance fighters surrendered, but the ŻOB command, including Mordechaj Anielewicz, the leader of the Warsaw Ghetto uprising, stood firm.

Anielewicz, his girlfriend Mira Fuchrer and many of his staff committed mass suicide by ingesting poison rather than surrender, though a group of about 30 eluded the SS by escaping through the only un-blocked door of the six.

[4][5] From the Stroop Report, 8 May 1943: The whole Ghetto was searched today by raiding parties... [We] are resolved not to terminate the large-scale operation until the last Jew has been destroyed.
