Ravensbrück was a women's forced labor camp that hosted some 70 satellite camps. Located about 80 km north of Berlin, it was opened in 1939, and designed to accommodate 6,000 prisoners. This number eventually swelled to 32,000 to accommodate the usual Nazi "enemies:" political undesirables, prostitutes, Gypsies, lesbians, and jews. They worked as slave laborers in arms and textile manufacture supporting the war. A number of prominent resistance women were executed, including members of the British Special Operations Executive, Catholic and Orthodox nuns, some royalty, communists, and Polish patriots. Some 150,000 passed through the camp where 30,000 to 40,000, including children, perished due to malnutrition, disease, exhaustion, or harsh treatment by the guards. Many of the guards were women, who gained a reputation for cruelty surpassing that of the male SS guards. Many prisoners were perfunctorily sent to death camps. Those sent upon arrival were never registered in camp records, so the total number is unknown. At the end of March, 1945, with the Red Army only hours away, the SS ordered over 20,000 prisoners on a death march. Many died but the survivors were rescued by a Red Army scouting party. Fewer than 3,500 sickly women and 300 men remained when the Red Army liberated the camp on April 30th, 1945.  Link. Map
