Mr Cornwell: I have been a Sharpe fan for years, having read all these books (more than once !) I decided to read the Grail Quest trilogy – I am currently nearing the end of Vagabond. As a keen longbow archer with an eye for historic detail, I am immensely pleased to read the accurate & intricate detail with which you describe the battlefield archery and fieldcraft of the medieval archer. How long did your research in this area take ? Matt Rentell
