"The Joy Divisions, appearing in Ka-tzetnik 135633's 1955 novel, The House of Dolls, describes a group of Jewish women in the concentration camps during World War II who were kept for the sexual pleasure of Nazi soldiers.
In the book, the barracks in which the women were kept were located in distant locations within existing concentration camps, usually close to the front lines. Troops on their way to the front spent a day drinking and molesting underage women. If they were not 'pleased' with their prisoner, they could have her killed. These female prisoners were better fed than other prisoners of the camp, and were enslaved until they died."
