Background
“Sasha (Pechersky), jumping up on a table, made a short speech in Russian, his native language. His voice was clear and loud so that everybody could hear, but also composed and slow. He told the prisoners that most of the Germans in the camp had been killed. There was no turning back. A terrible war was ravaging the world and each prisoner was part of that struggle. He promised that dead or alive, they would be avenged and so would the tragedy of all humanity. He repeated twice that those prisoners who, by some miracle survive, should forever be a witness to this crime.”
