Agincourt is a village in northern France. Near here in 1415, King Henry V of England won a decisive battle in the Hundred Years War. Though the French outnumbered the English four to one, at the end 5,000 Frenchmen lay dead while only 113 Englishmen were killed. This slaughter was partly accomplished by skillful use of the Welsh longbow, a weapon that spelled the end of the armored knight, the military basis of feudalism.
