Agincourt
The Battle of Agincourt was fought by King Henry V on 25 October 1415 (Saint Crispin’s Day) near Azincourt in northern France.
Despite greater numbers, the French forces were unexpectedly defeated
The English victory is attributed to the use of the English longbow in very large numbers, with the English and Welsh archers making up nearly 80 percent of Henry’s army. It is probable that many of the bowmen originated in Berkhamsted, turning the tide of a battle that changed the course of European history. The victory raised English morale and prestige, and crippled France.
