The Auschwitz Report — Poland
Slovak Jews Rudolf Vrba and Alfréd Wetzler escape from Auschwitz in April 1944 to compile the first comprehensive eyewitness report on the camp's killing operations and deliver it to the world.
On 7 April 1944 Vrba and Wetzler hid for three days then walked 80 miles to Slovakia. The Vrba-Wetzler Report, completed in late April 1944, provided the first comprehensive account of Auschwitz to reach Western governments. Vrba later testified at the Eichmann trial. He always maintained that the report's delayed distribution contributed to hundreds of thousands of Hungarian Jewish deaths.
