1759. The Year Britain Became Master of the World, Paperback/Frank McLynn

Although 1759 is not a date as well known in British history as 1215, 1588, or 1688, there is a strong case to be made that it is the most significant year since 1066. In 1759 - the fourth year of the Seven Years War - the British defeated the French in arduous campaigns on four continents and also achieved absolute mastery of the seas.
