The Gestapo prison Columbia-Haus in Berlin becomes a concentration camp.
Subordinate to the IKL are: Dachau, Esterwegen, Richtenburg, Sachsenhausen, Columbia-Haus, Oranienburg, and Fuhlsbuttel, with ostensibly 7,000 to 9,000 prisoners (official statement).
Concentration camp Oranienburg is closed.
In the Hohnstein trial in Dresden, SA members who staffed the Hohenstein camp are sentenced to prison for mistreating concentration camp prisoners. In November they are pardoned, without exception.
As a reaction to criticism from the Justice department on the increasing number of "unnatural deaths" in concentration camps, the Gestapo releases behavior guidelines for the guards.
Concentration camp Sachsenburg is dissolved.
