A Derbyshire man convicted of murder in 1867 was sent to the other side of the world to pay for his crime.
Daniel Marsh was one of thousands sent across the seas to Australia to free up space in British prisons. Which at the time were at full capacity.
Throughout his time in prison he sent letters home to the UK about his life in prison.
The letters being auctioned on Friday, have been described as the only known letters of this kind.
