We shall have to disagree then, my friend. The AS language and culture became dominant but the Germanics never supplanted the common folk. Francis Pryor in Britain AD paints a more extreme scenario than I can accept, but his view is that the AS invasion never happened and the Venerable Bade was nothing but a spin doctor. Peaceful trading and transition won the day for the Germans and the Brits were so impressed with grubenhausen that they built their own.
Give him a read and have a good laugh. We had better move off this topic soon as we are way out of prehistory now.
