Lonka Korzybrodska was an active member of He-Haluz, a resistance movement during World War II. She participated in missions until her capture and died imprisoned in Auschwitz in 1943.

Kashariyot were young women who traveled on illegal missions for the Jewish resistance in German-occupied Eastern Europe during the Holocaust. They smuggled goods, news, and other Jews in and out of the ghettos of Poland, Lithuania, and parts of Russia. While those who fought the Germans within the ghettos are often most celebrated for their heroism, kashariyot were essential in the survival of Jews within ghettos.
