We are not aided by the fact that boundaries shift, names change and cities come into prominence and fade away. We are certainly not helped by the numerous invasions of the Islands have turned everything topsy-turvy several times. Nothing in today's Britain is where Arthur left it. Nothing was in Arthur's day where Rome had left it, after the withdrawal.

Simply imagine the island of the 5th and 6th century. Loyalty often still lay along old Celtic tribal lines, in spite of the Roman occupation of Britain. Incursions of Saxons from the south and east forced Romano-Celts to either leave their homes or fall under the invaders' rule. Irish slavers raided Welsh villages, and the Picts or Scots harried the northern borders. And it would be foolish not to suppose that there were internecine conflicts as well. The land was not stable. There were no ordinance surveys. There wasn't even the feudal system of later years to keep everything in place. And Christianity (with it's tradition of monkish record-keepers) was being wiped out by the invading Saxons. It was truly a land in flux.
