This book is not action packed; it is more about the internal struggles of Hervey as he comes to terms with the loss of his wife and the leaving of his daughter with a governess and Hervey's sister Elizabeth - possibly at some cost to her hopes for a suitable marriage. We open in Rome (where coincidentally Mallinson was serving as he wrote the book) with Hervey having left his regiment and travelling with his sister. We then meet Percy Shelley, which is an amusing interlude, and catch up with Captain - now Commodore - Peto, who is perhaps a little taken with Elizabeth. There is a some brief road brigandage, but it is more or less pointless, and this little interlude closes with Hervey deciding to rejoin the sixth, which is being posted to India.
We then have Hervey's return as a Captain, and having to raise a troop - both horses and men - out of very little. We have scenes of training in India, and finally a mission, and some action at the end to close out the book. Hervey is no longer quite the naif he was, visiting a local prostitute (mostly offscreen) and questioning his religious faith: it will be interesting to see where this goes.
If all that sounds a little tame...well...I suppose it is, but soldiering is a lot more than battle. By the standards of "battle" a hell of a lot of Aubrey-Maturin is idle sailing around. What Mallinson is giving us is a fun story where much of the conflict is internal, within Hervey himself. As well as this, it is an accurate and detailed look at the life of a Regency-era cavalry Regiment. As a reader, you can feel the heat of India, the oppression of the jungle, the sweat of horse and rider. This is putting the history in historical fiction, and that's not a bad thing.
