The Invention And Use Of The Trabuco Before Gunpowder

The Trabuco is a unique siege weapon that dates back to the middle ages. It was used in wars to crush the masonry walls of the enemy or when shooting projectiles over them into cities. The weapon’s origin is traced to China around 400 BC and later entered Europe in 600 AD. Its use was not abandoned until the discovery and outbreak of gunpowder.

The counterweight blunderbuss that appeared in Muslim and Christian countries around the Mediterranean could throw projectiles of up to 140 kilograms at high speed. Moreover, these weapons were highly effective because they could be used from a distance of up to 800 meters from the intended target according to .

The traditional Trabuco is sometimes referred to as the balancing Trabuco to distinguish itself from the traction Trabuco. The latter was created before the popular balancing Trabuco. Today in Brazil, the name Trabuco is used to refer to large caliber shotguns or revolvers especially those of old manufacture like bacamarte.

How it Works

In contrast to mangonels, catapults, and ballistae, the Trabuco doesn’t use complicated mechanism. In fact, its growing popularity during the middle ages was attributed to the simplicity of its manufacture and maintenance on Furthermore, its prominence rose because of its ability to launch heavier projectiles at a greater distance compared to similar arms in use back then.

The mechanism behind the Trabuco consists of transforming gravitational potential into kinetic energy. However, not all potential energy in the mechanism is transformed, rather, a part of it dissipates in the form of sound and heat. What’s more, the size of the Trabuco’s counterweight was directly proportional to its projectile’s velocity. As a result, larger counterweights launched stronger projectiles at

Modern physics has linked potential difference, kinetic energy, and potential gravitational to the weapon’s operation. It is presently used to explain these physical principles to students.

1. The Tensile Trabuco

The first traction Trabuco were human-operated. The beam’s short end was moved by people and required a lot of cooperation and teamwork. To date, the biggest documented trabuco as described in Wu Jing Yao de Zong’s military treatise was operated by 250 people. It hurled stones weighing 140 pounds at 80 meters. These machines were rare because they required complicated logistics to operate.

Despite the weapon’s ability to deliver four shots per minute, its use faced numerous limitations on . The biggest one was that it was hard to control the large teams of people who operated the Trabucos. It was also difficult to achieve shots of similar force. It was replaced in the eleventh century by the hybrid Trabuco.

2. The Hybrid Trabuco

When Arab merchants introduced the traction Trabuco in the Middle East, its design was refined to make it more efficient. Weight was added to the arm’s short end adding an extra reach. The hybrid Trabuco used in the thirteenth century had the capability of hurling up to 400-pound stones as evidenced in Damietta, Egypt.

Europeans first come across the hybrid Trabuco during the crusade wars. They were impressed with the idea of the weapon as well as its power and decided to implement it. They also improved the design to increase its accuracy. This was after they realized that using a constant weight and human strength would allow the Trabuco to give a greater weight.

3. The Counterweight Blunderbuss

The improvements made to the hybrid Trabuco by Europeans gave rise to the counterweight blunderbuss. These weapons hurled stones weighing over one ton for a greater distance. For ammunition, these weapons were loaded with stones, cows, horses, sand barrels, living prisoners, and human heads.

The use of Trabucos was discontinued only after the invention of gunpowder. As a result, guns and cannons were preferred for their accuracy and power.
