The gas chambers of Sobibor were one of the Nazis' best kept secrets. Sobibor killed an approximate total of 260,000 Jews, and only a few managed to survive and give evidence of the existence of the deathcamp. The vast majority of the escapees did not live to witness the day of liberation. Some were killed at later stages of the escape, and others died as fighters in the ranks of the partisans. 

The number of survivors is variously reported, but it is estimated by most authorities that only about fifty survived until the day of liberation.
