Trebuchet Vs Catapult – Do You Know The Difference?

Key Point: Trebuchets excel at long-range fortification attacks, while catapults are versatile for short-range assaults on both fortifications and infantry.

Today, we are discussing the topic of trebuchet vs. catapult. You will see 6 ways the trebuchet is different from a catapult. So, by the time you finish this article, you will see for yourself how these two siege weapons are different and why they were made differently. 

So, what are the 6 differences between a trebuchet and a catapult? Well, here they are…

6 ways the trebuchet and a catapult differ from each other: 

1) Design

2) Size

3) Range

4) Projectile

5) Accuracy

6) Complexity

These are the 6 key differences between trebuchets and catapults. Now, let’s get our hands dirty by going through each of the 6 points in detail. 

Trebuchet vs. Catapult – Design Difference

As you have likely seen in documentaries and movies. The Trebuchet and the Catapult look different from each other. 

A trebuchet is a large and complex siege engine that was powered by gravity.

It consists of a massive wooden frame, a long throwing arm, and a counterweight, usually made of heavy stones or lead. Here is a video demonstrating the difference in their design, it’s just 30 seconds long, but it explains the way each of these siege weapons converts stored energy into kinetic energy.

How catapults and trebuchets store energy

Are You Curious? If so, I suggest taking a look at this article on the Assyrian Siege Tower. The siege weapon they used to create an Empire. If you click here a new tab will open with the article. So, when you finish this one, you can continue reading. Now back to the main article …

To launch a projectile, the operator would have to load the arm with the shot, then release it. This allowed the counterweight to fall and pull the arm downwards. This movement would cause the arm to swing upward, launching the projectile over the walls of the target.

Trebuchets could also launch much larger and heavier shots than catapults. That made them effective at causing widespread damage and disrupting enemy fortifications.

A catapult in comparison is a smaller and simpler device. Typically it consisted of a throwing arm mounted on a sturdy frame. The arm was tensioned by a rope, a spring, or a torsion mechanism, and when released, it flings a stone, a bolt, or another projectile toward the target.

Catapults could be operated by a single person and could be reloaded relatively quickly, making them ideal for launching repeated attacks against an enemy position.

Now, for their size difference. 

Difference In Their Size

Trebuchets were much larger machines than Catapults. 

A typical trebuchet could be anywhere from 30 feet to 100 feet or more in length, with a throwing arm that measured 20 feet to 40 feet or more. The size of the counterweight could range from several hundred pounds to several tons. Trebuchets were usually operated by a team of several people and required a significant amount of space for their construction and operation.

In contrast, a catapult was generally smaller, with a frame that measured anywhere from 6 feet to 20 feet in length. The throwing arm could be as short as 3 feet or as long as 10 feet, and the counterweight, if present, was typically much lighter than that of a trebuchet. Catapults could be operated by a single person and were more portable, allowing them to be used in a wider variety of locations.

The Trebuchet was larger typically because the demands placed on it were larger than that of a catapult. The demands in terms of range I mean. This leads us perfectly to … 

Difference In Range

The difference in ranges for these two siege weapons is quite substantial. While of course, it depended on the size of the siege weapon but in general terms: 

A typical trebuchet could launch a projectile up to 300 yards or more. Some of the largest trebuchets were capable of launching shots over 500 yards. This ability to throw things long-range made trebuchets a formidable weapon for attacking castles and fortifications from a safe distance. 

Meanwhile, catapults, had a much shorter effective range, typically launching projectiles up to 200 yards or less. While this was still a significant distance, it placed the operator in closer proximity to the target and made the device more vulnerable to enemy counterattacks. However, catapults were still useful weapons, particularly for launching repeated, quick attacks against enemy positions. 

The trebuchet was a larger weapon capable of firing with greater ranges but it was slow to reload when compared to the catapults. The catapult’s small size and ability to fire more quickly (compared to the trebuchet) meant it was kept around despite its inferiority when it came to long-distance shooting. 

Now, that we covered how far they could throw things. Let’s see what things did they actually throw at people and walls … so it’s time we examine the. 

Difference In Projectiles

When it comes to the type of projectiles they used, trebuchets and catapults were notably different. 

Trebuchets were created to launch a diverse array of items such as: 

– rocks 

– flaming pitch balls (that must have been a terrifying sight)

– diseased animals & human waste

Biological materials, such as fecal matter and diseased animals were thrown over walls to cause panic and spread disease among the inhabitants of the city. The Mongols were particularly cruel with that tactic. 

Catapults, meanwhile, were primarily used for launching smaller and lighter items such as stones, bolts, and javelins. Although these projectiles were not as destructive as those used by trebuchets, they were more manageable to produce and could be launched quickly in succession.

This made it possible for the operator to carry out repeated, fast attacks against the enemy. The lighter weight of the projectiles also made catapults more portable, allowing them to be employed in a variety of locations.

The distinction in the type of projectiles utilized by trebuchets and catapults was in line with the different purposes they served in medieval warfare. Trebuchets were built to launch heavy and powerful projectiles to cause maximum damage. Catapults on the other hand were intended to launch lighter projectiles for repeated, swift assaults.

What about the accuracy of a trebuchet in comparison to the Catapult? Let’s find out. 

Accuracy Of A Trebuchet Vs. Catapult

When it comes to hitting their targets, trebuchets and catapults differed in their level of accuracy. Trebuchets, due to their longer range and more powerful launches, were less accurate than catapults. Their massive size made it difficult to precisely aim them at specific targets, and the projectile would often travel in a high arc, making it hard to hit smaller, more distant targets. Almost impossible. 

Catapults, on the other hand, were more accurate than trebuchets. They could launch their lighter projectiles in a relatively straight line (much smaller arc), and the smaller size of the device made it easier to aim and control the trajectory of the shot. This allowed the operator to direct their attacks at specific targets and structures, making them a more effective weapon for siege warfare.

The difference in accuracy between trebuchets and catapults was a result of the different designs and capabilities of each weapon. Trebuchets, with their long range and heavy projectiles, were less accurate but more destructive, while catapults, with their smaller size and lighter projectiles, were more accurate but less destructive.

So, finally, the little Catapult won a round. 

Now, what about the next part?

The Complexity – Trebuchet vs. Catapult 

Trebuchets were more complex than catapults in both design and operation. These medieval weapons were larger in size and required a more sophisticated mechanism, consisting of a counterweight and a sling to launch their heavy projectiles. Their construction also demanded a higher level of skill and resources, including a significant amount of timber, rope, and iron.

Catapults, in comparison, were less complex in design and operation. They were smaller in size and utilized a simpler mechanism, consisting of a spring or a torsion rope, to launch their lighter projectiles. This made catapults easier and quicker to build, as well as easier to operate in the field. Also, they were also more portable and could be carried to different locations. This made them a versatile option for medieval armies.

In short, the distinction in complexity between trebuchets and catapults was rooted in the different purposes they served in medieval warfare. Trebuchets, with their heavy projectiles and long-range, were more complex but more destructive weapons, while catapults, with their lighter projectiles and fast-firing capability, were less complex but more maneuverable and adaptable.
