The Battle of Agincourt took place on October 25th, 1415 between England and France during the Hundred Years' War. King Henry V of England defeated the French army, securing an important victory for England in its campaign to expand its territory in France. Though outnumbered, the English forces were able to defeat the overconfident, tired, and hungry French army due in part to the effectiveness of the English longbowmen. The battle resulted in many French casualties but few English losses and helped cement Henry V's reputation as a strong military leader.
