Alfréd Wetzler (aka Jozef Lánik) and Rudolf Vrba (born as Walter Rosenberg) escaped from Auschwitz after learning that construction and preparations were being made for the mass arrival of "Hungarian Salami" as those Jews were jokingly called by the camp guards, and wrote the Vrba-Wetzler report, also known as the Auschwitz Protocol, with help from the Bratislava Working Group. It was distributed to many Jewish and other organizations, including the Jewish Agency, in order to warn the Hungarian Jews. The recipients did not publicize the report.
