From Stones to Siege: The Life of a Trebuchet Operator Soldier

As a soldier operating a trebuchet siege weapon during a medieval siege, my duty is to launch projectiles at the enemy’s castle to weaken its defenses and ultimately facilitate its capture. I work in a team, receiving orders from the commander and following the overall strategy of the siege.

“The trebuchet was the ultimate medieval siege weapon, capable of launching projectiles weighing hundreds of pounds over long distances with deadly accuracy.”

Kelly DeVries, Professor of History at Loyola University Maryland and author of “The Artillery of the Dukes of Burgundy, 1363-1477”.

Our trebuchet is a massive weapon that can launch projectiles weighing up to 500 pounds at the enemy’s castle walls.

It requires a team of soldiers to operate, each with a specific role. One soldier is responsible for loading the projectile onto the trebuchet’s sling, while others work to adjust the tension of the ropes and the angle of the arm.

Once the trebuchet is ready, we wait for the commander’s order to launch. We carefully aim the weapon and release the projectile, which hurtles through the air toward the enemy’s castle. If we’re lucky, it strikes the castle walls and causes significant damage, weakening the enemy’s defenses and creating a breach for our troops to enter.

“The trebuchet was a powerful and sophisticated machine that played a key role in medieval warfare. Its use required skilled operators and careful planning, and it was capable of inflicting massive damage on fortifications and armies alike.”

Robert Liddiard, Professor of History at the University of East Anglia and author of “Castles in Context: Power, Symbolism and Landscape, 1066 to 1500”.

Our work as trebuchet operators requires precision and teamwork. We must work together seamlessly to load and launch the projectiles, and we must communicate effectively with other units to coordinate our attacks. We also must maintain the trebuchet and make any necessary repairs, as the weapon takes a significant amount of strain with each launch.

Throughout the siege, we remain focused on our mission and work tirelessly to launch as many projectiles as possible. We know that our efforts are crucial to the success of the siege, and we take pride in our ability to operate such a formidable weapon.

As trebuchet operators, we play a vital role in medieval warfare. Our ability to launch massive projectiles at the enemy’s castle can be the difference between victory and defeat. By working together and remaining steadfast in our duty, we help ensure that our army emerges victorious from the siege.

Trebuchets & Projectiles

Trebuchets were medieval siege engines used to hurl large projectiles at enemy fortifications or troops. The objects that trebuchets threw could vary widely depending on the purpose of the siege.

Here are some of the most common objects that were thrown by trebuchets

Stones
This was the most common projectile used in trebuchets. Stones were effective at breaking down walls and causing damage to buildings.

Fireballs
Fireballs were often made of burning materials such as tar, pitch, or oil. They were used to set buildings or other structures on fire.

Diseased Corpses
In some cases, trebuchets were used to hurl diseased corpses into a city or castle, in the hopes of spreading disease and weakening the enemy.

Animals
Sometimes, trebuchets were used to throw live animals into a besieged area, causing chaos and spreading disease.

Human Prisoners
In some cases, trebuchets were used to launch human prisoners into a besieged city, in order to intimidate or demoralize the enemy.


Effective Distance of the Trebuchet

The effective distance of a trebuchet varied depending on its size, design, and the weight of the projectile being thrown. Generally, the larger the trebuchet, the greater its range.

A typical trebuchet used during the medieval period had a range of around 300-400 meters (984-1312 feet) when throwing large stones or other heavy projectiles. However, larger trebuchets, such as those used during the Siege of Acre in 1191, could reportedly throw projectiles as far as 500 meters (1640 feet).

It’s important to note that the accuracy of a trebuchet was not always reliable, and the distance that a projectile traveled could vary greatly depending on factors such as wind and the skill of the trebuchet operator

“The trebuchet was one of the most impressive and effective weapons of the medieval period, capable of throwing heavy stones, fireballs, and even dead animals over castle walls. Its use required a large team of skilled operators and engineers, and it was a testament to the ingenuity and creativity of medieval craftsmen.”

Anne Curry, Professor of Medieval History at the University of Southampton and author of “Agincourt: A New History”.
