In April 1944, 19-year-old Rudolf Vrba and fellow inmate Fred Wetzler became the first Jews to break out of Auschwitz. Under electric fences and past armed watchtowers, evading thousands of SS men and dogs, they trekked across marshlands, mountains and rivers to freedom. Vrba's mission: to reveal to the world the truth of the Holocaust. In the death factory of Auschwitz, Vrba had become an eyewitness to almost every chilling stage of the Nazis' process of industrialised murder. A brilliant student of science and mathematics, he committed each detail to memory, risking everything to collect the first data of the Final Solution. After his escape, that information would form a priceless 32-page report that would reach Roosevelt, Churchill and the pope, and eventually save over 200,000 lives. But the escape from Auschwitz was not his last. After the war, he kept running – from his past, from his home country, from his adopted country, even from his own name. Few knew of the truly extraordinary deed he had done. Now, at last, Rudolf Vrba's heroism can be known.
