This is not an easy read. The author is obviously knowledgeable and this book represents a culmination of tremendous knowledge and research. The book is a thesis containing a challenge to conventional thinking about the wars.
I don't fully know the conventional thinking on this war so the details on the challenge were hard to digest. I wanted to learn about the war --- and I did --- but there were narrative and organizational problems made it more difficult than it should have been.
One problem is with definitions. On p.28, where the author defines "bastard feudalism", which the author (who according to the dust jacket has written a book on this) considers a necessary condition of these wars, as a system where a lord could call all in his employ to pageantry or battle. As a lay person, this is my view of feudalism, so how "bastard feudalism" differs is not clear. Similarly, a new concept (to me), that of "entails in tail male" on p. 36, seems to be a method of oral or written testament to override inheritance by primogeniture, but this is not clear.
There are things for which better immediate connections would help. For instance, there are many mentions that the Yorkists are promoting a "reform" or "good government" agenda. Not until p. 172 is the agenda itself spelled out, and it contradicts the many pevious references to "reform agenda" (and also what seems to be part of the author's thesis), but fits the actions of the Yorkists: "However, the Yorkist programme had not proposed a reformed system of government. It entailed rather the better management of the existing system by good rather than evil counselors, in short, themselves."
Queen Margaret is mentioned several times in the first half. You learn that historians are split about her influence, but neither the debate, nor what she is doing is not defined is defined until, finally, on p. 152 comes the first evidence that she is a player, she raises an army in Scotland.
While I don't know this history well enough to critique the balance of events, Henry VI's mental illness comes and goes with no telling of what this illness was and how it vanished. This 2+ year period would seem to be a major event and a major influence in what happened next, but it is mentioned, not explained or analyzed. Similarly Richard, Duke of York who dominates the first half of the book is key to initiating this many years struggle, dies in battle and this is sum total of what is said: "Obviously the defeat at Wakefield and the deaths of both York and Salisbury were unexpected disasters for the Yorkist cause." It would seem that for a key player this would be a big event and it seems there should be something about how he was struck, his mourners/burial, his inheritance. If nothing is known, since Richard is so important to the story, the absence of information should be noted.
The plates are very good and appropriate. The publisher opted for b & w over color, making more of them possible than if color had been used.
The final chapter "The End of the Wars" and the Epilogue are very good and can be used as free standing commentary on these wars for informed readers. "The End..." talks about the significance of the wars both then and now.
Despite all the above, I got through it and learned a lot about this multi-generational war and its aftermath. It's hard to assign stars for an ambitious work like this when I don't have be background to critique its actual thesis. While there is 5 star information here, my experience of the book was 3 stars or less. I'm going to round this higher due to knowledge of the author and the work he put into the it.
