Szymon Srebrnik

His testimony along with that of the few other witnesses was critical to the prosecution of camp personnel and other Nazi officials, because of the destruction of evidence by the Germans of their mass extermination of Jews in Chełmno.

Srebrnik also won jumping contests and speed races which the SS organized for chained prisoners to participate in.

On January 18, 1945, two days before Soviet troops arrived and liberated the camp, the Germans shot and killed most Jewish Sonderkommando prisoners who took part in the disposal of Holocaust evidence.

[2][5] According to his own testimony, the German bullet missed the spine ("vital brain centres") and exited through his mouth without substantial blood loss.

[1] After his emigration to Israel, Srebrnik lived in a Kibbutz and went into military service, eventually taking part in four wars.
