Anglo-Saxons were not 'vikings' ( which is a stupid term because it actually means Pirate or something like that ), some of them may have had scandinavian blood in them, as did many cultures in western/northern europe, but to generalise and say Anglo-Saxons were descendants of scandinavians is false, some people may have had scandinavian descendants, but that doesn't really have anything to do with the subject.
English is a Germanic language influenced by some outside factors, Britons resided on the Island and the Angles, Saxons and other Germanic tribes settled in the south-east of England, integration obviously occured and the bloods were mixed, the language formed and we became HARD AS NAILS SON.
I said gone 'viking' in the West as 'viking' is in the archaeological record (runestones mainly) also used as a verb, something you do (ie. engage in piracy and raiding), and not only as a noun.
Angles and Saxons and Jutes followed the tradition of sailing West to the rich British Isles generations before the Danes and Norwegians (and a few Swedes and Balts) did so in the Viking Age, and as far as we know more or less displaced the local Celtic peoples (also Roman italic people, Romano-British and those from the faraway Eastern Provinces who had served in the legions stationed in Roman Britain), pushing them North and East, though certainly intermingling happened on some scale or another.
But part of my point was that Harald Godwinson's huscarls have more in common (genetically and culturally) with the invading Vikings than you or for example Victorian British have with the Anglo-Saxons of this time, many of them had come from the same areas and only few generations before, where British people of today have since had about a 1000 years of increasing genetic exposure.
This was not to provoke nationalism but rather to establish that the men fighting in above videos were all closely related and the interesting historical dynamics of the region of the time.
Former invaders (Anglo-Saxons), some of whom were pushed from the Jutland peninsular by invading Danes, were now defending their relatively newly-won territory against invaders from home, be it Danes, Norwegians or Normans, the latter themselves originally Viking invaders who after defending Normandy from their Viking kin now suddenly taking to invasion and west-ward expansion once more.
