On October 14, 1943, a revolt took place in the Nazi death camp "Sobibor," led by Soviet POW Alexander Pechersky. The "Sobibor" death camp was established by the Nazis in Eastern Poland in the spring of 1942. Over a year and a half, more than 170,000 Jews from Poland, the Netherlands, Slovakia, Austria, Germany, France, the USSR, and other countries perished in the camp. On October 14, 1943, a revolt broke out in Sobibor, led by Red Army officer Alexander Pechersky and Leon Feldhendler, a businessman from the Polish town of Żółkiewka. The rebels killed eleven SS officers, several guards, and escaped from the camp. Several hundred people took part in the escape, and over 50 of them survived the war. This was the only successful mass uprising in a death camp during the war.
