Battle of Agincourt (1415): English victory in the Hundred Years' War
A clear, neutral account of the Battle of Agincourt (25 October 1415): participants, tactics, weapons, course of the action, casualties, aftermath and its place in the Hundred Years' War.
Overview
The Battle of Agincourt took place on 25 October 1415 near Agincourt (Azincourt) in northern France. It was a decisive English victory during the Hundred Years' War in which a numerically inferior English force defeated a much larger French army. The English army, led by Henry V, had marched from the recently besieged port of Harfleur and was weakened by disease and fatigue. The principal French field commander that day was Charles d'Albret, Constable of France; the French king, Charles VI, did not personally command, in part because of his chronic mental illness.

Forces, terrain and opening moves
The battlefield was a narrow lane between two woods, constraining movement and restricting cavalry manoeuvre. The English army relied heavily on infantry and archers rather than mounted knights. French forces deployed large numbers of heavily armoured men-at-arms and mounted knights, who had to advance across a churned, rain-softened field. Mud, fencing, and the confined front all worked against the French ability to use their superior numbers effectively.
Weapons, tactics and the role of the longbow
English archers armed with the longbow played a central role. The longbowmen were protected by sharpened stakes planted in front of their positions and by occupying ground that channelled French attacks. The longbow offered a combination of range, rate of fire and ability to disrupt armored formations. French forces included crossbowmen and traditional mounted heavy cavalry; contemporary accounts and later analysis contrast the English longbow with the crossbow, noting differences in deployment, rate of fire and integration with infantry tactics.
The battle, casualties and prisoners
In the fighting, English archery and disciplined infantry resistance frustrated French assaults. Close-quarters combat developed as French men-at-arms became mired in mud and crowded together; English soldiers, including officers, joined the melee. Henry V himself is recorded as having been involved directly in the fighting and is said to have suffered an axe blow that his helmet helped to deflect (accounts of such wounds exist). Contemporary sources give widely differing casualty counts; many medieval chronicles exaggerate numbers. Modern historians treat precise totals cautiously: French casualties were heavy and included many nobles, while English losses were comparatively light, but exact figures remain debated.
Aftermath and significance
The immediate result was a crippling setback for French military prestige and a morale boost for England. The victory strengthened Henry V's position and contributed to the diplomatic momentum that produced the Treaty of Troyes in 1420, though long-term control of French territory remained contested. Agincourt became a potent symbol in English cultural memory, sometimes magnified by later chroniclers and dramatists. Historians emphasize both the practical tactical reasons for the outcome and the way that legend and national memory have shaped its reputation.
Key factors and notable points
- Terrain: a narrow, muddy front limited French deployment and advantaged defensive English formations.
- Longbowmen: massed archers disrupted and delayed French attacks, supported by stakes and infantry.
- Armour and mobility: heavy French armour and crowded approach made movement difficult in wet ground.
- Leadership and morale: Henry V's command discipline and the cohesion of English troops were important.
- Prisoners and ransom: capturing and ransoming noble prisoners was common practice; the chaos of the field sometimes led to killings of lower-status captives.
- Legacy: Agincourt is studied as an example of how tactics, technology and terrain can outweigh numerical superiority.
The battle remains one of the most studied medieval engagements: a mixture of clear tactical lessons and enduring myth.

Background
Causes of the dispute
The starting point and core point of contention of the Hundred Years' War, of which the Battle of Azincourt is a part, was the English claim to the French throne. After the English victories at Crécy (1346) and Maupertuis (1356), the first phase of this war ended with the Peace of Brétigny, concluded in 1360, which secured English rule over large parts of France. By 1396, the French had recovered much of the land they had lost to the English and secured it through a renewed peace treaty with England. Henry V, who ascended the English throne in 1413, renewed the claim to the French kingdom and resumed diplomatic talks to that end while recruiting an army of experienced soldiers paid directly by the English crown. After diplomatic negotiations broke down, he and his army landed at Harfleur (now the Seine-Maritime department) in Normandy on August 14, 1415.
On the French side, he was opposed by the insane King Charles VI. Among his imperial administrators were the Duke of Burgundy, John Fearless, and the Duke of Orleans, Charles de Valois, who with their parties of Bourguignons and Armagnacs fought a power struggle that almost paralyzed the French side in the war against the English. The town of Harfleur, besieged by the Anglo-Welsh army, was not helped by any French army and the town surrendered on September 22. Although a mobilization of the feudal armies in the French provinces took place after the fall of Harfleur, the armies of the dukes of Orleans and Burgundy would probably have fought each other if they had met. Thus, the army of the Burgundian Duke John Fearless remained behind and the Connétable, Charles I d'Albret commanded the French force.
The English march to Azincourt
About a third of the Anglo-Welsh army was dead or unable to fight after the week-long siege of Harfleur. With a remnant army weakened from day to day by an epidemic of rest, Henry V wanted to move to Calais, which had been the last bastion of the English crown in northern France since 1396. There he wanted to prepare himself for coming hostilities. The direct route from Harfleur to Calais was about 200 kilometers and led along the coast. Only the Somme represented a major obstacle on this route. In order to cross this river above the estuary, the Anglo-Welsh army moved further inland from October 13.
Along the Somme, French troops had occupied the crossings in time, so the English force had to penetrate further and further inland in search of a way to cross the Somme. It followed the course of the river, however, the French army on the north bank of the Somme kept pace with it. Henry V therefore decided to stop following the course of the river and, in order to throw off the French army, crossed the Santerre plain in a forced march. Near the towns of Bethencourt and Voyennes, they found two unguarded, though damaged, dams that allowed them to cross the Somme. By this time they had covered 340 km in twelve days. Therefore, Henry V let his army rest on October 20. From October 21 to 24, the army covered another 120 km. Henry V was aware that the French army must be on their right flank. Scouts were able to confirm this assumption on October 24. Although the French had already formed up in battle formation on October 24, the battle did not take place because of nightfall. The two armies camped within earshot of each other during the very rainy night.
Effect of the defeat
Militarily, France was so soundly defeated that the English regent Henry V was able to impose his war aims in the following years, occupying Caen and finally, five years later, imposing the Treaty of Troyes on the French crown, by which he married the French princess Catherine of Valois and made himself the successor of the French king Charles VI.
The scale of France's defeat also led to a realignment of Burgundian policy, which came to fruition in the Treaty of Troyes in 1420. The King of England was recognized by the Burgundians as King of France in order to work towards the formation of an independent empire.
