When Nazi Germany invaded the Soviet Union in June 1941, young Red Army soldier Simjon Rosenfeld was wounded and captured during the first weeks of the war. After years of imprisonment, forced labor, and survival in the Minsk Ghetto, he was deported to Sobibor, one of the Nazi regime's deadliest killing centers.

In October 1943, Rosenfeld joined a secret resistance group that organized the historic Sobibor uprising. During the revolt, prisoners killed several members of the camp staff and hundreds attempted to escape. Rosenfeld survived the breakout, spent months hiding in the forests of occupied Poland, and later rejoined the Red Army, fighting until the end of the war in Berlin.

He would eventually become the last known survivor of the Sobibor uprising, preserving the memory of one of the most remarkable acts of resistance during the Holocaust.
