The 1943 Sobibor Uprising, a significant act of resistance during the Holocaust, involved Jewish prisoners at the Sobibor extermination camp in Poland staging an armed revolt. This resulted in roughly 300 prisoners escaping, making it one of the most successful breakout attempts from a Nazi camp. The prisoners were driven by news of Allied advances and the destruction of other camps.  Key figures in the uprising included Alexander Pechersky, a Soviet Jewish POW, and Leon Feldhendler, a former head of a Jewish council.  The prisoners meticulously planned the rebellion, aiming to kill SS officers and guards to seize their weapons and escape into the surrounding forests. Pechersky and Feldhendler's leadership was crucial to the uprising's success.  Around 50 to 70 escapees survived the war.  The uprising forced the Nazis to close and dismantle the camp in an attempt to erase its existence.  The Sobibor Uprising demonstrated the courage and resilience of the prisoners and served as a symbol of resistance against tyranny.
