Analysis of information sources in references of the Wikipedia article "Bullenhuser Damm" in English language version.
The closer the Allies got, the greater the pressure on the SS to make the evidence of their horrific human experiments disappear. Probably on April 20, 1945, the order came from an SS office in Berlin: "The Heissmeyer department is to be dissolved." In plain language: The 20 boys and girls must be murdered, along with their four carers. An SS commando pulled the children out of bed in the evening and took them to school on Bullenhuser Damm, a satellite camp of Neuengamme concentration camp in East Hamburg.
