Prison barracks

As if merely being in a concentration camp weren't enough, for difficult cases the camp included special prison barracks with isolation cells and interrogation (read: torture) facilities. It was not unusual for prisoners to spend months alone and blind shackled in tiny cells. One of the prison's inmates was Pastor Martin Niemöller, who famously remarked about not saying anything while they took away his neighbors. Nobody was left to say something when they came for him. (Niemöller survived both Sachsenhausen and Dachau, and became a vocal pacifist.):First they came for the Communists, and I did not speak out—
because I was not a Communist;
Then they came for the socialists, and I did not speak out—
because I was not a socialist;
Then they came for the trade unionists, and I did not speak out—
because I was not a trade unionist;
Then they came for the Jews, and I did not speak out—
because I was not a Jew;
Then they came for me—
and there was no one left to speak out for me.Prison regulations extensively detailed permissible methods of torture; quite a few of the exhibit texts seem to be more annoyed by the fact that the guards occasionally exceeded the rules than by the fact that they were using torture in the first place. Official favorites included suspension from poles (resulting in bone dislocation and a slow, painful death), beating with iron truncheons and whipping (not allowed on bare buttocks until the regulations were amended in 1942).
