The place is an isolated strip on the Forest of Dean side of the Severn Estuary between Lydney and Chepstow, near the Oldbury nuclear station. The farmer, Willy Guest, found his flock in a state no one involved could account for. Around forty sheep were injured and sixteen were dead. The archive holds no date for the episode. Not even a year, which is a real weakness of this entry.
What is on the record
One telling on one channel, resolving three claimants: Guest and two others named as Robert Hulse and Jane Glover Hill. The reason this case is worth its file is that something was done rather than only seen. Carcasses were radiographed and the radiography is reported to have ruled out firearms. What it showed instead were crushing injuries, strips taken from the jaw, missing tongues and blind holes on each side of the head described as clamp-like.
That is a specific set of findings and it is the most testable material in the file. It is also the material the archive does not hold. There are no images, no veterinary report, no laboratory paperwork and no primary documents of any class. The radiography is described in the telling. The archive has the description and not the plates.
The proximity to Oldbury is stated in the account and it is worth handling carefully. Nearness to a nuclear installation is a fact of geography rather than a mechanism. Nothing in the record connects the two beyond the fact that they are close. Ordinary explanations are not excluded here either. Nothing in the file settles what could produce crushing injuries and symmetrical head wounds across a whole flock.
Why it sits where it does
The case grades L3 on several claimants attached to one connected event and it rests on testimony alone. Without the radiographs or a veterinary record it cannot reach the document-corroborated tier. The missing date holds it back further. What the record holds is a farmer, a ruined flock and a described set of findings. What killed those sheep is not resolved here.
