English- ashamed of our Anglo-Saxon past?

Recently this summer I visited Scarborough(E.Yorkshire) with my girlfriend on the way home we decided to detour slightly and visit the scene of arguably one of the most violent battles in British history...Stamford Bridge (25th Sept, 1066).

When we arrived there, we struggled even to locate anything to commemorate the climactic and hugely-important battle and, when we finally did(near the S-bend over the bridge- the newer one nearby, not the long-gone 'original') we were peed off to find just one small and briefly-written plaque bolted into a huge pillar near a car park...like a trivial afterthought!

Though Harold's other gruelling all-day and evenly-fought bloody battle (Hastings) deservedly gets huge attention, this bruiser deserves much more high-profile attention?

It's like we supposedly patriotic English/British are ashamed of our Anglo-Saxon past?

Barely more mention than Scarborough council's tourist board's clueless ignorance regarding their own town's utter sacking in Sept 1066 by Hardrada's southward-bound invasion fleet of 300 shipfuls of hardened viking warriors, which then sailed up the Humber and fought two major pitched battles(Fulford Gate 20th Sept & Stamford Bridge five days after)?

Had it not been for this brutal, day-long struggle on 'battle flats' at Stamford near York(which saw the deaths of over 80-90% of the fearsome Norwegian King Harald hardrada's invasion army, including he himself plus Tostig, 'turncoat' brother of the English King) - the second of three huge battles during 1066 - King Harold would have been ready for William(not exhausted and depleted), on the south coast(over 230miles away), with a fresh, full and prepared Saxon army & navy- with archers(and not still straggling along the 'great north road' hastening to follow and join Harold in the south).

Had this been so, and bearing in mind that the English fought a ferocious and even battle at Hastings all day anyway, it is likely that the Normans would probably have been battered back into the sea before disembarkation, assuming the Saxon fleet hadn't scattered them first, which clearly would have drastically altered English/British history?

And what mention in our history books of the hugely important achievements of Kings Edward the Elder(Reconquest 910-18) and Athelstan(the colossal battle of Brunanburh in 937)- Alfred the Great's son and grandson respectively?

Poor and shameful neglect, me thinketh?
