The Arthurian Dark Ages

This is a link to Guy Halsall's site in which are re-printed his thoughts on the 'Arthurian' Dark Ages period, first published in Wargames Illustrated in the late '90s.  Great to read the thoughts of a man who is both a renowned historian as well as a passionate wargamer.  And of course while this is set earlier than the Viking Age, the ideas are very portable a few hundred years
