Not only does the British Museum continue the above-mentioned tradition, it also owes its very existence, in its current form, to emulation of Napoleon's cultural legacy. 
In the exhibition and this catalogue there are, as well as the very numerous prints, a number of ancillary objects, such as coins, medals, pottery and suchlike - even some genuine Napoleonic 'relics' - as well as a few examples of the more ordinary categories like drawings and sculpture, which, if you take the trouble to read about them, offer up all kinds of fascinating insights.
But the stars of the show are undoubtedly the beautifully reproduced prints. These range from earnestly pro-Napoleonic images, mostly but not exclusively French, via examples of straightforward classical allegory and beautifully depicted battle scenes, to the satirical prints of numerous nations, chiefly - and unsurprisingly given the title of the book and exhibition - British. The works of these British artists, and James Gillray's most of all, show very clearly why this is regarded as a golden age of English satirical printmaking.

Once the brief peace of Amiens ended, when England declared war on France, the perpetual assault on the country viewed as the hotbed of revolution by those Ancien Regime powers was resumed. They never let up until after Waterloo. Apart from a few debacles (in South America and Holland), Britain's active role was limited. Thanks to the audacity of Nelson, which cost him his life, we scored two notable naval successes. But on land our only sizeable contribution, until Waterloo (and even there we were only a small part of a mixed allied force) was the Iberian or Peninsular campaign, which didn't get off to the best of starts.
As Napoleon's French media liked to point out, England's chiefly role was as agitator and financial backer (see two prints down). It was the wars France's enemies continually made upon her, funded by British money (the need to fund these wars saw the introduction of income tax here in Britain) that raised Napoleon, and as long as Britain bankrolled successive coalitions - seven formed against France in this period - his gift for swift and decisive warmaking would help him become ever more powerful. So it could be argued that they effectively forced him into becoming the caricature warmonger they had always made him out to be.
On the other hand it has to be borne in mind that he himself said 'Conquest has made me what I am, and conquest alone can maintain me'. But this was, I believe, something he said in his memoirs, when a lifetime of near continual conflict lay behind him. Napoleon also said that 'History is the version of past events that people have decided to agree upon'. It's interesting that, in relation to the history of his times, the argument rumbles on.
Fortunately the book and the show include both the official and the dissenting British views, as well as those of our allies and adversaries. And just as there was here, there was a diversity of opinion amongst the French, from royalists to Bonapartists, and beyond. The image of the British as a 'nation of slaves' fighting and financing wars to prevent the spread of liberty was a central plank in Napoleon's propaganda. This was a view rarely aired this side of The Channel, the or since. It's good that this show doesn't gloss over these other views.
Tim Clayton and Sheila O'Connell have written a clear, informative, and fairly well balanced text. They go further than most British writers in pointing out the multiple readings of these histories that are possible. But it's still, as the exhibition's title says, a resolutely British story. More than the still-vexed politics, which continue to present a conundrum Britain and Europe struggle to solve, it's the pictures of prints and other objects that are the main attraction in this book: there are lots of fantastic memorable images here, as well as some that are less delightful but still very interesting. Gillray's work is what I enjoy looking at the most, even if I don't always like the propaganda he's peddling.
There are also some terrifically beautiful 'straight' prints, such as Francois Aubertin's Passage du Grand St. Bernard, a French print celebrating an early and audacious move by the young Napoleon, or Matthew DuBourg's Field of Waterloo, an incredible work that beautifully depicts a truly appalling scene, the bloody aftermath of the battle that ended Napoleon's career. Dubourg was of French extraction, but worked in England. It's interesting that his mixed cultural heritage resonates with the scene he depicts, in which the various nationalities are reduced to a common suffering. The Field of Waterloo is hardly the sort of triumphalist image that many in Britain favoured.
Of particular interest to wargamers, perhaps, in addition to the magnificent images by Aubertin and Dubourg (see above), is a series of panoramic Watercolours, painted only days after the battles at Waterloo and Quatre Bras. Rather ghoulishly corpses can be spotted here or there in the fields, and troops and civilians are also evident sparsely populating what had been only days before close-packed scenes of carnage. These watercolours show the battlefields as they were at the time, and would presumably be useful to gamers seeking to recreate the battle and the terrain, as no doubt many will attempt to do this year. 
This is a gem of a book, produced to accompany a fascinating show. I already had Mark Bryant's The Napoleonic Wars in Cartoon, which is a fun but comparatively superficial look at much of the same material. This gorgeous volume allows one to explore similar territory in much greater breadth and depth. I love it, and think it's an essential purchase for the Napoleonic history nut.

 France and the other European nations had their own traditions of printmaking and satire, and the balance between freedom and censorship outside the British Isles shows, in both similar and different ways, how Napoleonic France, its empire, and these other nations dealt with similar issues. But obviously the focus here is mostly on Britain and France, with other nations, Russia and Spain for example, being treated in a subsidiary manner.
 Does anyone know if the observation derrick (behind the French lines) pictured in one of these images was erected before of after the battle?
