Destruction Evidence for the Fall of Roman Britain?

[Flavivs Aetivs]

The stations were supposedly built c.AD370, and one (of the others, I think) has coin deposits up to Honorius. So we could perhaps date the destruction to c400 or so.

Actually there's an argument for redating coin deposits in Britain to the mid 5th century despite being from earlier emperors. It was based on studies of coins from Hadrian's wall.
