Survivor: Auschwitz, the Death March and My Fight for Freedom. Sam Pivnik

In 1939, on his 13th birthday, the Nazis invaded Poland. Sam Pivnik survived the two ghettoes set up in his home town of Bedzin and six months working on the processing ramp at Auschwitz, where prisoners were either taken away for entry to the camp or gassing.

After this harrowing experience, he was sent to work at the brutal Furstengrube mining camp. He could have died on the 'Death March' that took him west as the Third Reich collapsed, and he managed to swim to safety when the Royal Air Force mistakenly sank the prison ship Cap Arcona in 1945.

On 14 occasions he should have been killed, yet now in his 80s, Sam tells the story of his life, a tale of survival against the most extraordinary odds.
