This book is one of the least impressive of the English Monarchs series. The historical issues with Wolffe's analysis are brought out in the Foreword by John Watts. Much of that Foreword is devoted to arguing that Wolffe's book is outdated in its research - that the current view of Henry is that of a "well-intentioned duffer" as opposed to Wolffe's presentation of him as more assertive and personally responsible for the failings of his reign. I think the Foreword would have worked much better following the text. When one reads first thing that the main thesis of the book is now considered wrong, it does not exactly excite the reader to want to go through the book itself. If it had followed the text, Watts's commentary would have been a fine corrective. However, that is not the reason for my problems with the book.
Large sections are poorly written. In much of Part III on "Majority Rule," the paragraphs read like lists of data and they often wander off the thesis statement of the paragraph. My main complaint is that the author very often did not structure paragraphs in a way that highlights the key issues in the paragraphs. It is one data point followed by another, followed by another, followed by another, etc. with a mind-numbing succession of names, many of them never brought up earlier or explained. I ended up trying to pick out the main point amidst an array of data. Very irritating. Sentences also need some editing. Clauses pile on top of clauses, sometimes appropriately, but often with extraneous points thrown into the sentence. I am sure that Wolffe wanted to use these sentential additions to enlighten the reader about context but the effect is confusion and difficulty in following his point. One other very bothersome point to me was that critical points, like the death of the Duke of York, are added in a few sentences at the end of a paragraph, this particular one dealing with the "rebels" in general. (The sentence starts out "In any case York and his son were slain in the melee.." - this for a man who dominates much of the last part of the book.) This "tossing in" of important points in paragraphs that are about broader issues occurs several times and is another example of lack of organization as to what is important in the paragraph and what is not.
This lack of well-written paragraphs is not true of the whole book. The first section on Henry's minority is much better organized and written. So are parts of the last third of the book. But the really important section about Henry's last years and the Lancaster-York war is quickly (in fact, very quickly) glossed over. In this section a great number of important events are crammed together and again the reader has a sense of a string of "facts" tossed together to make a paragraph. Given the importance of this time period, the lack of any developed explanation is a real weakness.
As Watts notes, the book emphasizes Henry's role in the loss of the English possessions in France. Even if Henry was more passive that Wolffe makes him, there is real drama that shines through at times in these sections amidst the lists of research points masquerading as paragraphs. Despite some bright spots, the book as a whole is not one I would recommend.
