In 1704 a Scottish sailor called Alexander Selkirk was marooned on a remote and uninhabited island in the South Pacific. He spent the next four and a half years there, completely alone, struggling to survive using little other than his wits. How did he come to be there, how did he manage to survive for so long, and what was life as a castaway like?
