I bought this book because of my overall interest in the Napoleonic Wars and its very high rating on Amazon; it is billed as a history of the Napoleonic Wars with a more global perspective than most similar books, which focus on Europe. And indeed, this book has much detail about the period of the Napoleonic Wars in places such as India, Persia, Turkey, the Americas, etc, as well as a thorough treatment of Europe.
That said, other than the bits about India, Persia, etc., I didn’t learn that much about the period, and frankly I’m not particularly interested in those parts of the world. The book very much focuses on diplomatic and political, rather than military, topics, and is generally a rather dense read–it reads like a text book… While the book has some 960 pages, only about 650 of them are text, while the rest are notes.
I would recommend this book to anyone very interested in the Napoleonic era in non-European parts of the world, otherwise there are shorter, more interesting books to choose from.
