Researchers have identified a 700-year-old set of remains from Stirling Castle as the first confirmed casualty of a trebuchet. The skeleton, known as Skeleton 150, shows catastrophic injuries consistent with a high-velocity impact.

The 160 fractures of Skeleton 150

The physical evidence found on Skeleton 150 provides a visceral look at the lethality of medieval siege engines. According to the report, the remains exhibit over 160 fractures in total, a level of trauma that suggests an overwhelming force. Specifically, the skeleton shows nearly 60 zigzag-shaped breaks across the ribs and a deep, severe fracture in the shoulder.

The damage to the head was equally severe, with the skull alone sustaining more than 60 fractures.. These specific patterns of breakage indicate that the individual was struck by a heavy object traveling at an extreme speed, which is characteristic of the projectiles launched by a trebuchet .

The 1997 excavation beneath Stirling Castle's royal chapel

The remains were not discovered recently, but their significance was only just realized. As the source reported, Skeleton 150 was originally unearthed in 1997 during excavations at Stirling Castle in Scotland. The individual had been buried alongside eight other people beneath the castle's royal chapel, suggesting a mass burial event common during periods of conflict.

For decades, these remains sat in storage without a clear cause of death. it was only through a modern re-examination that the unique intensity of the skeletal trauma was identified, transforming a generic archaeological find into a landmark piece of military history.

How Dr. Jo Buckberry linked medieval trauma to car crash forensics

The breakthrough in identifying the cause of death came from an unexpected parallel in modern medicine. Dr. Jo Buckberry , an arcchaeologist and medieval warfare expert at the University of Bradford, recognized the fracture patterns on Skeleton 150 from a forensic anthropology workshop. Dr. Buckberry noted that the injuries mirrored those typically seen in high-velocity car crash victims.

This comparison is critical because high-velocity trauma was virtually unheard of in the medieval era, save for the use of massive siege engines.. By applying modern forensic standards to 700-year-old bones, the University of Bradford researcher was able to conclude that only a weapon like a trebuchet—capable of hurling massive stones over great distances—could produce such devastating results.

The missig identity of the Stirling Castle casualty

Despite the clarity regarding how the person died, several critical details remain unknown. The report does not identify the specific battle or siege that led to the death of Skeleton 150, nor does it provide the name or rank of the individual. It remains unclear whether the victim was a defending soldier at Stirling Castle or an attacker caught in the crossfire.

Furthermore, the source does not specify the exact nature of the projectile that caused the 160 fracutres. While trebuchets typically launched large stones, the specific weight and material of the object that struck Skeleton 150 have not been verified, leaving a gap in the reconstruction of this specific historical event.
