The second issue is one I often find myself mentioning in this special-interest niche of ours, military history, and that's editing. The Infantry volume has some pretty shocking moments, as when the back jacket blurb announces that the book is about cavalry. But this Cavalry volume, whilst correct on the rear dust jacket, is littered with editorial gaffes that suggest it has never been proof-read.
For example, take the first three Rocco plates: the first shows Chasseurs a Cheval, but the caption is for Grenadiers a Cheval. The second is Empress Dragoons, but the caption describes Chasseurs a Cheval. The third, a Grenadier a Cheval... well, it's not made clear in the text what body of cavalry is being referred to. Awful!
This jumble of misplaced captions is bad enough, but there's worse, as on pages 114-115 (shown above), where the left page shows photos of horse bridles/reins, and the right a sword belt and sabretache. But both bear identical captions describing a schabraque! This is, frankly, appalling and inexcusable in a book whose RRP is a hefty £40!
In conclusion, I would say that this potentially excellent book is currently very notably spoiled, partly by the dry data-heavy nature of the text itself, but much more so by the sloppy or seemingly non-existent editing . Nevertheless, whilst pretty disappointed, particularly after the anticipation generated by the previous Infantry volume, I'm still very glad to have this. For all its faults, and they aren't insignificant, overall it's still both fascinating and informative.
 The photo I've used is a reproduction item.
 Here's another and not altogether untypical instance of the need for better editing, p. 218: 'The eclaireurs of the Guard was a corps of cavalry eclaireurs of the French Imperial Guard...' Come on! Such redundant tautology shouldn't reach the printed page.
NB You may notice that I'm rather interested in the Eclaireurs! I was looking forward to learning more about them. And I did. But I was also deeply disappointed not to find better images of them.
