Though the abdication, exile, return and ultimate fall of Napoleon is well covered by a vast range of both popular and scholarly histories, less is available to the general reader on the political and diplomatic manoeuvrings of 1814-15, usually under the generic title of "The Congress of Vienna." This colourful historical narrative, which is enlivened with countless vignettes and anecdotes, brings the whole period to life. While Napoleon, for once, is a mainly background figure, albeit a menacing one, three larger than life characters dominate the story - Metternich, Tallyrand and Alexander I - but it is to Mr.Dallas's credit that he breathes life and interest into the fourth main player, Castlereagh, a much less charismatic personality. The secondary cast includes Britain's Prince Regent, France's Louis XVIII, the monarchs of Prussia and Austria, Wellington and Blucher, Austria's spy-network (with the ace spy still today identified only as "**"" ),a host of mistresses and courtesans (often closely related, despite differing political affiliations) and a plethora of diplomats, while the walk-ons range from Ludwig van Beethoven to minor Austrian civil servants. A surprise is the extent to which the gouty and corpulent Louis XVIII, briefly returned from his travels, only to be sent packing again within months, emerges as curiously attractive and sympathetic. As in his splendid biography of Clemanceau, Mr.Dallas excels in breathing life and interest into bygone crises - notably, in this case, the near collision between Austria, Priussia and Russia over the fate of Saxon. A particular triumph of the book is the extent to which the climax of Waterloo is not allowed to dominate the narrative to the detriment of less well-known events. For the general reader interested in the Napoleon period this book is indeed a treat - highly recommended.
