The middle ages were times characterized by warfare though weapons were not as sophisticated as they are today since not even guns were present. Enemies relied on large forces and fortifications to guard their territories and bases. To breach such security measures, one war siege machine was discovered, called the Trabuco. It was a weapon that could hurl and sling massive weights over enemies’ fortresses breaking them down within a few hits and bringing havoc upon armies. The Traction Trabuco preceded the Balancing Trabuco as more efficient and powerful versions followed later.
The Chinese are credited with the making of the first Trabuco around 400 BC using it to fly projectiles such as fire stones over concrete walls of their enemies. They used the weapon to break walls and gain access to the inside of enemies’ zones. A Chinese commander is thought to have developed the traction Trabuco which they used to beat Mongol invaders in a Chinese city they had captured. With a capacity to throw stones 140 kg weights at high speeds across 800 meters the Trabuco was highly effective than any other weapons of its age. Its accuracy is only compared to the modern-day revolver where the Chinese used it in biological warfare launching dead and infected people into besieged areas spreading diseases.

The weapon then spread to Persia, and later Europe. The Vikings used it to attack Paris in while the Nordic people used it to besiege Angers in 86 BC. Around 1191, it spread to Italy before it went to England in 1216. The British troops constructed a Trabuco as a backup for their insufficient firearms in 1779 when defending the Strait of Gibraltar against Spanish army. Herman Cortez is the last recorded man to have used the Trabuco when fighting against the Aztec capital city that he captured although the Trabuco never worked.
The Trabuco worked like a giant sling where a long bit of wood was levered on a motor with the string tied on the longer end of the lever. A stabilizer or counterweight was used to hold the shorter side. The advancement led to more counterweight and more projectile distance and weight. However, with the discovery of gunpowder, the Trabuco was deserted.
