2018 marks the centenary of Nelson Mandela’s birth.

He seized centre stage during a historic trial in 1963 and 1964.But there were eight others who, like him, faced the death sentence. They too were subjected to pitiless cross-examinations. To a man they stood firm and turned the tables on the state: South Africa's apartheid regime was in the dock.

Recently recovered archival recordings of those hearings transport us back into the thick of the courtroom battles.
