We will study navies and sea power, on the international stage, c.1890 to the present, especially navies as a vital part of the wider context of twentieth-century history. The emphasis will be on strategic and grand strategic, rather than tactical themes, although these will feature in case studies (e.g. the Battle of the Atlantic). Topics will include Mahan and the classical maritime strategists, the world wars at sea, sea power and the British empire, the Cold War, the Falklands War, current issues and the future of sea power, naval command, and the personal experience of naval warfare.
