Meet the only known trebuchet casualty in history

Archaeological and historical analysis has identified the remains of what is believed to be the only known human casualty of a trebuchet attack in history. The discovery relates to a medieval siege during which a defender was struck by a small boulder launched from a trebuchet at close to 300 kilometers an hour.

The high-velocity impact struck the unlucky defender's upper back, smashing his bones and crushing him beneath the heavy stone. The man's skeleton was subsequently recovered from beneath the chapel of Stirling Castle in Scotland, where it lay alongside the remains of several other individuals.
