Comprehensive and well laid out, The Battle really benefits from Barbero's use of short pithy chapters. Each is enjoyably punchy and succinct, and the large number, and rapid progress you can make through them, make for a galloping good read.
Talking of maps, the maps here are all grouped together near the front of the book, and are okay, although I've seen clearer/better. The inclusion of a portion of the Ferrari & Capitaine map - see image below - as used by Boney (and also the source for Wellington's maps), is a nice touch. There are also a good number of evocative illustrations.
The grand scale of this intense battle is humanised by Barbero's liberal peppering of his narrative with piquant observations from participants, making for a gripping read. This is the sort of exciting history that can kickstart a lifelong passion for a subject. I was glued to The Battle from start to finish, and thoroughly enjoyed it, so I'd recommend it highly.
