captured fighters lobbed hidden grenades or fired concealed handguns after surrendering. There were also clashes at night between small groups of insurgents and German patrols at night. On 8 May, the Germans discovered a large dugout located at Miła 18 Street, which served as ŻOB's main command post. Most of the organization's remaining leadership and dozens of others committed mass suicide by ingesting cyanide, including Mordechaj Anielewicz, the chief commander of ŻOB. His deputy Marek Edelman escaped the ghetto through the sewers with a handful of comrades two days later. On 10 May, Szmul Zygielbojm, a Bundist member of the Polish government in exile, committed suicide in London to protest the lack of action on behalf of the Jews by the Allied governments.

These figures did not include Jewish collaborators, but did include the "Trawniki men" and Polish police under his command. Other sources have questioned the number of German casualties.
