1944-07-05 Intercepted Warnings: Nazi Letter Forwards Report on the Extermination of Hungarian Jews at Auschwitz-Birkenau
On July 5, 1944, Horst Wagner, head of Jewish affairs at the German Foreign Office, sent critical information in a letter to SS-Obergruppenführer Ernst Kaltenbrunner, chief of the Security Police and SD. Wagner shared an intercepted radio message between the British Embassy in Bern and the Foreign Office in London. According to the intercepted communication, a Hungarian official had reported that “nearly half of the total 800,000 Jews in Hungary have already been deported” and were “being sent to the death camp at Birkenau near Oswiecim in Upper Silesia.” The message urged immediate military action – “bombing of the railway lines from Hungary to Birkenau” and “strikes on the facilities of the death camps” to disrupt the extermination operations.
