On April 30, 1945, Soviet troops liberated the Ravensbrück women’s concentration camp where women from over 20 countries had been imprisoned. The death rate in Ravensbrück was very high, with more than 90,000 prisoners not making it home. The prisoners took an oath to never forget the black night of Ravensbrück and to destroy Nazism. The atrocities that the prisoners had to endure can be seen in photographs or learned from eyewitness accounts.
