On St Crispin's Day, 25 October 1415, Henry V's English army crushed the French in the most famous battle of the Hundred Years' War. His outnumbered force of men-at-arms and archers repelled the repeated charges of the French mounted men and killed or captured the leading members of the French nobility. The encounter changed the course of the war and made a mark on English and French history that endures to this day. In this compelling new study, medieval historian Michael K. Jones looks critically at the historical evidence and retells in graphic detail the story of this extraordinary campaign. He also provides a fascinating tour of the sites associated with it - Harfleur, Henry V's route across northern France and the Agincourt battlefield itself.
