The word “Chivalry” comes from the French Cheval (Horse). To be a knight was, by definition, to be a horseman. The medieval Warhorse was not just an animal; it was a weapon system. It struck with hooves and teeth. It carried 300lbs of armored man into a wall of spears. But was it the giant, plodding shire horse we see in movies? (Spoiler: No).
This article explores the biology, economics, and tactics of the equestrian middle ages.
The Types of Horse
It wasn’t just “a horse.” There was a strict hierarchy.
- The Destrier: The Rolls Royce. The true warhorse. Rare, expensive, and exclusively a stallion (for aggression).
- The Courser: The BMW M3. Fast, agile, used for skirmishing and hunting. Many knights fought on coursers because Destriers were too expensive to risk.
- The Rouncy: The Ford Transit van. The general-purpose riding horse used by squires and mounted archers.
- The Palfrey: The Mercedes S-Class. A smooth-gaited horse used for long-distance travel (and by ladies) because it didn’t bounce you out of the saddle.
The Destrier: Myth vs. Reality
Movies show knights riding massive Clydesdales or Shires.
- The Reality: The Destrier was smaller, likely 15-16 hands (the size of a modern Friesian or Andalusian).
- Agility: A heavy cart horse cannot turn quickly. A warhorse needs to spin, stop, and sprint. It needed the build of a heavy hunter, not a plow horse.
- The Temperament: They were trained to bite and kick. In battle, a good horse fought with you.
The Cost: A Mortgage on Hooves
A good Destrier could cost 80 marks (£50). To put that in context: A skilled laborer earned £2 a year. A warhorse cost 25 years of a workman’s wages. If your horse was killed in battle, it was a financial catastrophe. This is why knights often targeted the enemy’s horses—it was economic warfare.
Breeding: The Medieval Genetic Engineering
Medieval lords were obsessed with genetics. They knew you couldn’t just catch a wild horse.
- The Stud Farms: Great lords maintained huge stud farms (Parks).
- The Spanish Connection: The best bloodstock came from Spain (The Jennet) and Naples. These horses had Arab blood, giving them speed and fire.
- The Mix: They crossed these hot-blooded Southern horses with the cold-blooded, heavy Northern European horses. The goal was the “Golden Mean”—heavy enough to carry armor, but hot enough to charge.
Logistics: Feeding the Beast
A warhorse was a high-performance athlete. You couldn’t just feed it grass.
- The Fuel: It needed “Hard Feed”—oats, barley, and beans.
- The Quantity: A Destrier ate the equivalent of three peasant families’ grain rations every day.
- The Groom: You needed a dedicated squire just to groom the horse. If a horse’s sweat wasn’t cleaned off under the armor, it would get saddle sores and be useless combat-wise.
The Unsung Hero: The Sumpter Horse
For every Destrier, an army had 20 Sumpter Horses (Pack Horses).
- The Logistics: An army marches on its stomach, but it carries that stomach on a horse. Sumpters carried the tents, the arrows, the horseshoes, and the food.
- The Vulnerability: If you killed the enemy’s sumpter horses, his army starved. Raiding the baggage train (as happened at Agincourt) was a standard, if unglamorous, tactic.
Medieval Veterinary Science
How did they treat a sick horse?
- The Farrier: The blacksmith (Marshal) was also the vet.
- The Remedies: It was a mix of practical care and superstition.
- For Colic: Drenching the horse with ale and garlic (actually works).
- For Lameness: Bleeding (phlebotomy) to “balance the humors” (doesn’t work, weakens the horse).
- For Evil Eye: Hanging a “Hag Stone” (stone with a natural hole) in the stable.
The Armor: Barding
As arrows got sharper, horses got armor. This is called Barding.
- Chamfron: Armor for the face/head.
- Peytral: Armor for the chest.
- Crupper: Armor for the rear. Full plate barding was incredibly heavy, which is why it only appeared in the late middle ages. Before that, horses wore “Trappers”—long cloth coats (often padded with mail underneath) displaying the knight’s heraldry.
The Transport Revolution: The Horse Collar
While the Destrier got the glory, a humble invention changed the world: The Horse Collar.
- The Problem: In ancient Rome, horses pulled carts with a strap around their neck. If they pulled too hard, they choked. They could only pull light loads.
- The Solution: The rigid padded collar (invented in China, arrived in Europe ~900 AD) shifted the weight to the shoulders.
- The Result: A horse could now pull a heavy plow. This allowed farmers to plow the heavy, clay soils of Northern Europe. Food production exploded. The population boomed. This “Agricultural Revolution” funded the building of the cathedrals and castles. The warhorse conquered the land, but the plow horse made it worth conquering.
Famous Warhorses of History
History records several individual horses whose fame rivals that of their riders.
- Bucephalus: Alexander the Great’s legendary stallion. Said to be terrified of his own shadow, only Alexander could calm and ride him. Bucephalus carried Alexander from Greece to the edge of India. When he died of battle wounds in 326 BC, Alexander founded a city in his honor—Bucephala—near modern Jhelum in Pakistan.
- Marengo: Napoleon’s favorite grey Arab stallion. Captured in Egypt and named after the Battle of Marengo (1800), he carried Napoleon at Waterloo. He survived the battle, was captured by the British, and lived to the age of 38 in England. His skeleton is on display at the National Army Museum in London.
- Copenhagen: The Duke of Wellington’s chestnut stallion at Waterloo. Wellington rode him for 17 hours without a break during the battle. When Wellington finally dismounted, Copenhagen kicked out—perhaps the only creature who ever got away with assaulting the Duke of Wellington.
The End of the Destrier
As armor disappeared, the heavy horse became obsolete in war. Cavalry became “Light Dragoons” or Hussars—fast men on fast horses with sabers and pistols. The Destrier didn’t die out, though. Its DNA went into the Shire Horse and the Draft Horse, which powered the Industrial Revolution before the steam engine took over. The magnificent beast that once carried a king now pulled a beer wagon.
Conclusion
The age of the knight ended not just because of gunpowder, but because of the Pike. Once infantry learned to stand firm with 18-foot spears (pikes), the cavalry charge was suicide. The horse, the symbol of aristocratic dominance, was defeated by a stick held by a peasant. But for 400 years, the thunder of hooves was the sound of power.
