This is a difficult book to rate. It has some very positive aspects. It is written in a breezy style which is easy to read. The complexities of 15th-century politics are bound to be difficult for any reader who isn't already well-versed in the period but Bicheno does much to help with numerous family trees and tables. The military complexities are also elucidated through clear maps, campaign diagrams and battle plans - would that other historical writers would make such good use of maps. Bicheno also makes good use of recent battlefield archaeology research.
However, there are down-sides too. The breeziness comes with a certain amount of chippiness, which is not attractive. To take just one example, in the introduction to the 'Further Reading' section the author writes (in response presumably to a critical review of a former book), 'As it appears I did not make it clear enough last time, this is not an academic bibliography.' A good editor could surely have persuaded him to drop this petulant remark.
Bicheno is entirely and unrepentantly partisan. He makes Marguerite d'Anjou the heroine of the first part of the story, which is refreshing. In general he is very positive about the female protagonists. He is also very much anti Richard III. He may be right but the evidence is not so clear-cut as his scornful treatment of the pro-Ricardians suggests; there will always be room for re-interpretation.
I don't know enough about the period to evaluate the accuracy of Bicheno's account but he makes some assertions that must be questionable. Again, one example must suffice: in speaking of Richard III's denunciation of Thomas Grey, Marquess of Dorset, for immorality and adultery, he says 'it is hard to imagine what constituency in bawdy England might have shared his obsessive prudery'; but this is to assume that English society was a monolith with only one opinion. Not everyone in England was 'bawdy' and there were undoubtedly many who believed very sincerely the church's teaching about morality or who just felt strongly about the sanctity of marriage.
While I enjoyed reading this book, I will be looking for a more balanced and scholarly account of this intriguing period of our history.
