Barker is a medievalist and biographer, and this is a paperbound reprint of her 2005 book. The battle of Agincourt (October 1415), has long been acknowledged by historians and popular culture to be a defining moment in British history; for some, it also marks the downfall of chivalry and the ushering in of the Early Modern period. At Agincourt, Henry V, outnumbered deep in French territory, defeated the French under Charles VI, utilizing the longbow to great effect but also controversially killing all but the most important French prisoners to prevent a battle on two fronts. She examines the preparations, campaign, battle, and aftereffects from the point of view of the English, arguing that despite claims that the campaign at Agincourt contributed to strife that brought about the English War of the Roses, an outcome that included Henry V losing at Agincourt would have had devastating ramifications for England. This book is intended for general readers interested in late medieval history and warfare. Annotation ©2008 Book News, Inc., Portland, OR (booknews.com)
