Many books about medieval battles are based on little more than guesswork, but here is one which uses documentary, archaeological and topographical evidence to present a well-argued and convincing assessment of what really happened. The author seeks to probe the mindset of the commanders - by referring to the military manuals they would have studied - and questions why some noblemen and knights were prepared to risk everything to help an obvious impostor (Lambert Simnel), rather than commit themselves to King Henry VII. Simnel's Irish soldiers - previously portrayed as a disorganised rabble - are shown to have been a force to be reckoned with, and an in-depth analysis of the fire-power unleashed by the royal archers testifies eloquently to their courage. I was particularly intrigued by the role which Queen Elizabeth Woodville, Bishop Robert Stillington and Francis, Viscount Lovel played in the conspiracy, and by chapter 7 which must surely be the last word on Lovel's strange disappearance. All in all an excellent read which left me feeling that I had been told about the battle by someone who had fought in it. The 'guided tour', which can be followed on foot or by car, will be very useful when I go to see Stoke Field for myself.
