Most other prisoners of the early camps were soon set free again—not because of outside intervention, but because the authorities felt that a brief period of shock and awe was normally enough to force opponents into compliance. As a result, there was a rapid turnover in 1933, with the places of released prisoners quickly filled with new ones.
The duration of detention was unpredictable. Prisoners who expected to regain their freedom after a few days were mostly disappointed, but it was rare for them to remain inside for a year or more. Longer spells were served in the bigger, more permanent camps, but even in a large camp like Oranienburg, around two‐thirds of all prisoners stayed for less than three months.^244^
The result was a constant stream of former prisoners back into German society, and it was these men and women who would become the most important sources of private knowledge about the early camps.
