Operation Reinhard:
Belzec Deportations

Arad (Belzec) lists 246,922 deportees from within the General Government area alone, and a total of 600,000 killed in all, primarily Jews, with perhaps a few hundred to a few thousand Gypsies as well. He adds,

This figure was confirmed by the Glowna Komisja Badania Zbrodni Hitlerowskich w Polsce (Main Commission for Investigation of Nazi Crimes in Poland) and was accepted by the judical authorities of the Federal Republic of Germany. (Encyclopedia, Vol. I, 178)

Deportations to Belzec ended in December, 1942, and the transports stopped. Most of the Jews in the General Government were already dead, and Sobibor and Treblinka would handle any that weren't.

Information about Belzec is scarce, as very few escaped death there. One who did, Rudolf Reder, who escaped in November, 1942 after four months in the camp, recorded his testimony in Krakow, in 1946.
