A study based on ca. 700 personal stories of Jewish survivors of Ravensbrück, including ca. 200 testimonies held in the Yad Vashem archives; information from memoirs; and interviews conducted with survivors after the war or during 1997-2005 by Agassi and the team of scholars from Israel and Germany who worked with her, as well as with relatives of survivors who are no longer alive. The percentage of Jews among Ravensbrück prisoners was small, thus this camp was sometimes neglected by scholars of the Holocaust. Divides the history of the Ravensbrück camp (1939-45) into five periods, and presents a sociological portrait of the Jewish population in each period. Gives the distribution of the Jewish prisoners by countries of origin, reasons for arrest and incarceration, age, marital status, etc. Dwells on the prisoners in the satellite camps, the evacuation marches in the last stage of the war, and the rescue of some of the prisoners by Count Bernadotte in February-March 1945. Notes manifestations of antisemitism on the part of some non-Jewish prisoners. There was little group-wide social organization among non-political Jewish prisoners in Ravensbrück, only small group relationships. Resistance was limited to small-scale sabotage at in work places. Nonetheless, the very survival in Ravensbrück constituted a type of heroism.
