The battlefield lay on 1,000 yards of open ground between two woods, which prevented large-scale maneuvers and thus worked to Henry’s advantage. On the morning of October 25, the battle commenced. The English stood their ground as French knights, weighed down by their heavy armor, began a slow advance across the muddy battlefield. The French were met by a furious bombardment of artillery from the English archers, who wielded innovative longbows with a range of 250 yards. French cavalrymen tried and failed to overwhelm the English positions, but the archers were protected by a line of pointed stakes. As more and more French knights made their way onto the crowded battlefield, their mobility decreased further, and some lacked even the room to raise their arms and strike a blow. At this point, Henry ordered his lightly equipped archers to rush forward with swords and axes, and the unencumbered Englishmen massacred the French.
Almost 6,000 Frenchmen lost their lives during the Battle of Agincourt, while English casualties stood around several hundred. Despite the odds against him, Henry had won one of the great victories in military history.
