On October 25, 1415, French and English forces fought the Battle of Agincourt, a famous English victory during the Hundred Years War.
Two months earlier, Henry V of England crossed the English Channel with over 10,000 men. He enforced a siege on Harfleur in Normandy. The town surrendered after 5 weeks, but by then Henry had lost half of his men to disease and battle. He proceeded to march his army to Calais, from where he would return to England. However in Agincourt there stood an army of 20,000 Frenchmen, waiting to fight the exhausted Englishmen.
The battle commenced at 11 A.M. on October 25. The French knights, weighed down by heavy armor, were bombarded by English archers, wielding their innovative longbows. 6000 Frenchmen lost their lives, compared to the English death toll of just 400. From that day forward Henry V's fame lie in winning one of the great military victories in history. After further successes in France, he was named heir to the French throne in 1420, but died before he could inherit it.
