HMS Pickle is the unsung hero of the British navy. In 1805 Britain had just won the most significant sea battle in history, Trafalgar. But how to get the message home to an expectant nation? Enter the Pickle, the smallest ship in the fleet, a little boat with a revolutionary new design that beat her bigger rivals back to Britain to deliver the news. Sailor and writer Tom Cunliffe sets out in the Pickle and tells the story of a boat that, against all the odds, delivered the most important news in Britain's maritime history.
