1944 October 7, BIRKENAU (AUSCHWITZ II) UPRISING
David Szmulewski, one of the leaders of Birkenau's underground, and of the Jews of the Sonderkommados, who worked in the gas chambers and crematorias, blew up
crematorium IV. Rosa Robota, one of the heroines of the Auschwitz underground, succeeded in smuggling explosives out of a munitions factory. Rosa was caught and tortured but refused to give away any of her comrades. Her last words scribbled on a piece of paper just before she was hanged were "Hazak V'Arnatz"--Be Strong and Brave." After killing several SS men, the group escaped, although few survived.
