Admiral Sir John Norris : and the British Naval Expeditions to the Baltic Sea 1715-1727 /David Denis Aldridge.

This book covers the naval, military, political and diplomatic history of Sweden, Denmark, Hanover, England and Russia during the Great Northern War. It is chiefly a biographical study of Norris who commanded British expeditions in the Baltic Sea. The British naval presence was important for Britain's diplomacy and trade with the Baltic powers. Norris was a serving naval officer but also a representative of George I, whose dual role as King of England and Elector of Hanover placed him in a difficult political situation regarding the Northern powers.
