This is the story of an extraordinary period in British criminal history, brought to life through unique surviving records held by the UK National Archives. For over two hundred years, tens of thousands of convicts were sentenced to be 'banished beyond the seas', mostly to Australia and to destinations which became the stuff of legend - Botany Bay, Van Diemen's Land, Norfolk Island. This book follows their epic voyages across the world's oceans, recapturing the perils and unexpected pleasures of life at sea in fresh and fascinating detail.
