This is the first comprehensive naval history of a nation with many important, but often little known, naval connections. Covering a broad historical span, from the Romans to the present day, the book examines the naval forces of the independent Welsh rulers, the part played by seapower in the English conquest, the stories of such great Welsh seafarers as Nelson’s friend Sir Thomas Foley, the history of Pembroke’s royal dockyard, and the importance of Welsh copper and, later, coal, to the predominance of the Royal Navy in the eighteenth and nineteenth Centuries. Chapters examine the part played by Wales and the Welsh in the naval sides of both World Wars, and in subsequent operations such as the Falklands. Britannia’s Dragon was shortlisted for the Mountbatten Maritime Literary Award in 2014.
