This is were the discussion came from. You said "after Romans withdraw". So that was the period I was thinking of.
If we're talking about the time-period of this map, then the Romans were still in control, so I'm not quite sure what we would be discussing.
And yes, I would say that we "know" nothing (or practically nothing) of the facts of history in the dark ages in Britain.
