This is an odd book in several ways, and while I'm happy with it, it could easily have been twice as long. I'll explain the "oddness" but I'm not complaining. I can recommend this one.
In a very real sense this book is an expansion of, and riff upon, Thomas De Quincey's essay "The English Mail Coach." The author essentially assumes that the reader is very familiar with that work, because he refers to it without explanation more than half the time. (I expect that the majority of this book's readers will not, in fact, be all that familiar with De Quincey, which makes this an odd choice.)
The book is subtitled "Witnessing Waterloo" and at first I thought it was going to take a world-wide perspective on the battle, as there were such early hints. In fact, this is essentially about the British view of the battle, and the effect on British politics, and the British self-image. There are brief chapters describing what was happening on the battlefield that Sunday, intercut with what was happening back in London, and a few selected places elsewhere in Britain.
The selection of persons to observe upon is both interesting and puzzling. Family members of soldiers fighting in the battle are an obvious choice. There are a couple of artists whose connection with the battle is that many of their artist models for well-known paintings were, in their day jobs, soldiers in some of the showier units, like the Life Guards Cavalry. (We then follow some of these models who are in the battle, and one who has been left behind in London.) There are a couple of young ladies who find themselves in prison, condemned to death. Their stories give a slice of the culture, so that makes sense. But there are others, like Lord Cochrane, also in jail, and Byron, who have interesting stories, but don't seem very relevant to the battles going on in Belgium. The result of the randomness of these deliberate choices is that I wasn't always sure why I was being told what I was being told, and in a few cases never did find out.
Still, the stories had interest. I especially like that Crane focuses on the anti-war leaders in Britain, and the Bonaparte sympathizers; as well as those simply weary of fighting the French.
There are citations in the back, and a few footnotes, but often the book expects you to be familiar with various legends and myths of the battle. While I am widely read on the subject of the Waterloo Campaign, I found myself having to look things up rather often; and feeling that I should have been given that one extra sentence of explanation that would have solved the issue.
Again, despite some oddities, I enjoyed reading this quite a lot. Despite all I've read about Ligny, Quatres Bras and Waterloo, I was never bored. I got some writing ideas, and I have been inspired to revisit De Quincey. A win, all around.
