Dear Mr Cornwell, I am Brazilian and I follow your books since I was a boy, the first book I bought was The Winter King in 2000. When I bought the book Azincourt, could not fail to establish a link between this battle and the Battle of Aljubarrota, between Portugal and Castile. I know you will probably never write anything about this battle, but I think you may know about it. So I wonder if there is any book you recommend to get more information about this battle. Sorry my poor English, and thank you for your attention. Marcus de Almeida
