On October 25, 1415, a decisive battle took place at Agincourt in northern France. The army led by King Henry V of England, despite being much smaller in number than the French, defeated the elite French knights with amazing tactics and the power of their longbowmen. This battle is not only one of the most famous battles in the Hundred Years’ War, but also completely changed the landscape of medieval warfare. So, how did the English longbowmen defeat the French knights? This article will delve into the key factors of this battle.

Background of the campaign: Henry V’s expedition

In 1415, King Henry V of England decided to restart the Hundred Years’ War in an attempt to retake French territory. He landed in Normandy with about 12,000 soldiers and laid siege to Harfleur. However, the siege consumed a lot of time and manpower, and disease and supply problems caused serious casualties in the English army. In the end, Henry decided to lead the remaining 6,000-9,000 men to retreat to Calais and try to return to England.

However, the French assembled a large army to intercept the English. Estimates of the French force range from 20,000 to 36,000 men, mostly men-at-arms and elite infantry. The two sides met in a narrow stretch of farmland at Agincourt, and battle ensued.

The British Army’s Tactical Advantage: The Deadly Power of the Longbowmen

Despite being outnumbered, the English army’s tactical arrangements were extremely sophisticated. Henry V took full advantage of the terrain and longbowmen and adopted the following key strategies:

1. Terrain selection: Narrow battlefield limits the French charge

The battlefield of Agincourt was located between two forests, with a width of only about 800 to 1,200 yards. This terrain greatly limited the French cavalry’s charge space, forcing them to squeeze together and unable to take advantage of mobility. In addition, the heavy rain the night before made the battlefield muddy, further slowing down the pace of the heavily armored knights.

2. Longbowmen’s defensive fortifications: wooden stake array

The English longbowmen inserted sharpened wooden stakes in front of the formation to form a simple defensive barrier. These stakes could effectively block the cavalry charge and force the French knights to dismount and fight, thus losing their impact.

3. Longbow range and firepower coverage

The English longbow had a range of 250-300 yards and could fire 10-12 arrows per minute. When the French charged, thousands of longbowmen fired arrows at the same time, creating a dense rain of arrows. According to records, the English army may have fired more than 500,000 arrows in the early stages of the battle, causing a huge psychological and physical blow to the French army.

4. French tactical mistakes

The French army relied too much on traditional knight charge tactics and had chaotic command. Many French noble knights rushed to charge, resulting in a crowded formation and even trampling on each other. In addition, although their armor was strong, they moved slowly in the mud, making them sitting ducks for longbowmen.

Battle process: Massacre in the mud

After the battle began, the French army first sent out a cavalry charge, but was quickly blocked by the longbowmen’s rain of arrows and the wooden stake array. Subsequently, the French heavy infantry was forced to advance on foot, but due to the muddy terrain and dense arrows, their advancement was extremely difficult.

When the French finally approached the British line, they were exhausted. The British infantry took the opportunity to launch a counterattack, using the advantage of close combat to defeat the immobile French knights. Due to the narrow battlefield, the French army could not retreat, and many were crushed to death or captured.

A classic example of the David and Goliath defeating the Strong

The Battle of Agincourt is one of the most famous examples in history of a small force defeating a large one. The victory of the English army was not accidental, but a perfect combination of tactics, terrain and weapon advantages. The longbowmen’s accurate shooting, the limitations of the muddy battlefield and the French army’s command errors all contributed to this legendary victory.
