The Battle of Agincourt (1415): How Henry V's Outnumbered Army Won the Impossible Victory

By Princess Charlotte (Medieval Warfare Expert)

Every country has a battle that becomes legend. For England, it is hard to argue against that battle being Agincourt. Even people who know very little about medieval history have heard of it. And there is a very, very good reason for that. The real story of events is every bit as dramatic as any myth. Infact, I don't think you'd believe the myth!

On 25 October 1415, King Henry V found himself trapped and outnumbered 5-to-1 against a far superior French army. Experts believe that there were around 6,000 English soldiers, up against 30,000 Frenchmen.

Not great odds. It would have been a terrifying sight.

Henry's army had spent weeks marching through northern France. Many of his men were sick. Supplies were running low. The French had gathered a much larger force and were determined to stop him reaching safety, which means killing him.

Everything pointed towards a complete and utter disaster.

The battlefield itself was a narrow strip of land between two woods in northern France. Heavy rain had turned the ground into thick mud. The English took up a defensive position and waited. And then the French attacked the English lines...

What followed became one of the most famous military victories in history, not just British history but in the entire history of warfare anywhere in the world.

The exact numbers remain debated by historians, but what can't be debated is that Henry's army was hugely outnumbered. The French force contained many of the most powerful nobles in the kingdom and expected an easy'ish victory. Instead, the muddy ground became just as much as an enemy and Henry's forces.

Heavily armoured men-at-arms struggled forward through churned earth while English longbowmen and infantry held their positions and launched barrage after barrage of arrows. The arrows hit their mark and you really do not want to be hit by an arrow fired from an English longbow.

As more troops crowded into the narrow battlefield, confusion grew. Men slipped. Formations collapsed. Momentum disappeared. And it descended into utter chaos across the French lines. They became easy targets and were picked off without remorse. The French had learned very little since the Battle of Crecy!

By the end of the day, thousands of French soldiers lay dead, including a remarkable number of noblemen. English losses were comparatively light. Incredibly, historians estimate that between 13,000-20,000 French lost their lives across that muddy stretch day. In comparison, Henry's army lost between 70-100 men.

The victory transformed Henry V into a national hero.

Five years later, the Treaty of Troyes recognised him as heir to the French throne. For a brief moment it seemed possible that England and France might one day be ruled by a single king.

But Henry died in 1422 at just thirty-five years old. He never got to wear the French crown he had fought so hard to claim.

Agincourt remains famous because it was an impossible achievement. A much smaller army pitted against a far larger, superior enemy. They should not have won, let alone deliver such a comprehensive and incredibly one-sided victory. It still feels like a myth, but it happened. The reality of the battle was not magic or destiny. It was leadership, discipline, terrain and a great deal of luck.

And longbows, the most deadly weapon to appear on a medieval battleground.
