Introduction
On 11 January 1943, SS-Sturmbannführer Hermann Höfle, coordinator of Operation Reinhard(t), sent top-secret telegrams on its death toll to SS officials Adolf Eichmann at the RSHA in Berlin and Franz Heim at the Security Police in Kraków. These messages – intercepted by the British – provide precise data on the mass deportations – totaling 1,274,166 Jewish victims – to the extermination camps at Belzec (B), Sobibor (S), Treblinka (T), and the Majdanek / Lublin (L) concentration camp by the end of 1942.
