Thanks Paradox.
(I get abit frustrated having to re-explain to each and every person (everywhere not just here/now). I'm not sure how to present this so that i don't have to keep re-explaining it all to so many persons?)
Firstly see my first post/reply above.
My only 2 or 3 original sources where the 12 battles section in 'Historia Brittonum' of "Nennius", and the 9 Saxons Shore forts part in the Notitia Dignitatum, plus the actual 9 geographic sites that the ND/SS forts have been identified with/as. We orignally noticed that both lists (HB & ND) had 9 sites, and that some of the names were similar, but i dismissed it because there was only some matches (not all 9) and also because they didn't seem to match in number and order.
Eg: 9 battle sites/9 forts, "9 badon/1 branodunum", "5 fort guinnion/2 gariannonum fort", 4 reculver (baetasiorum)/3 bassas, 5 rutupi (legio ii augusta)/6 city of the legion.
But a year or so later someone told me that Dubglas "black water" had been identified by some as river Blackwater (Essex), while about the same time someone's post on Arthurnet mentioning Gariannonum directed/lead me to the Ravenna cosmography where i noticed that Garieni/Yarmouth better matches Glein than Guinnion. (None of this was really looking for a match betewen the 2, it was casual/unexpected.) I then noticed on casually checking the 9 SS/ND forts and 9 HB battle sites again that we had a dozen matches all matching in name or meaning and number & order.
[1] garieni/1 glein, [2] othona (Blackwater)/2 dubglas "black water", [3] reculver (baetasiorum / bassa the priest)/3 bassas, 6 Dover (white)/5 Guinnion "white/holy", 5 Rutupi (legio ii augusta)/6 city of the legion, (8 anderida/8 agned?) (9 adurni/9 badon).
It was a suddenly amazing/shocking dawning/realising moment then seeing the 9 battle sites matching the 9 forts from Yarmouth to Portsmouth or Southampton (and being militarily/strategically sensible/obvious). From then when i was convinced by such a strong match i have never doubted (though always tried to be objective/careful) and the more i have had to reconsider it in order to answer/show other people the more evidences (some stark/strong/amazing) we have found. The match for Tribruit wasn't found until a little while later when we found the meanings of the name match the Lemanis area. We now have all 9 sites matching in name or meaning, in nature (all the details of the HB and other sources), and number and order. There is no way it can just be coincidence or wrong that all 9 match all in number and order.
For more indepth answer/details see our most recent 9 battle sites paper at
http://www.allempires.com/forum/ebook_view.asp?ForumID=14 (though i have to update a few chapters since the historum forum debating).
Yes there are a few enough specific details from the HB (and other sources). But we have only proven (to any objective person not to highest archsceptic academic standards) that the two/three lists (HB & ND (&/or actual sites)) of 9 sites match, we have not yet proven enough that the battles were actually fought there then, though we have shown that there is seeming possible evidences at/around the sites (& in records) for the battles actually fought there then.
1 Glein matches Gariannonum/Garieni/Yarmouth in name, number/order, mouth, river, etc.
2 Dubglas matches Othona/Blackwater in name/meaning, river, number/order, etc.
3 Bassas matches Reculver in name/meaning, number/order, river, etc.
4 Caledon matches Kit's Coty/Weald in names/meanings, number/order, forest/wood, etc.
5 Guinnion/*Alborum matches Dover/Albion in meaning, number/order, fort/fortlet, etc.
6 city of the legion matches Richborough in legion, city/urbs, number/order, etc.
7 Tribruit matches Lemanis in: the meanings of Tribruit match Lemanis/Lympne/Romney area (then), number/order, etc.
8 Agned/Bregion matches Anderida/Pevensey in meanings &/or names (eg Bre-guoin "white hills"), number/order, etc.
9 Badon matches Adurni/Portchester in name, number/order, hill/mt, number slain, etc.
ps I just remembered i forgot to add that further proof/evidence/confirmation was later found in that the Wonders of Britain seem to match the same 9 actual sites. Some are stark and to my mind undeniable such as Cruc Mawr matching the "large cruciform platform" at Richborough, Amr's tomb matching Countless Stones, etc.
There are also further confirmations from other lists (that also seem to match our HB &/or ND) such as the 9 Pa Gur battle sites, the "12 Monasteries" list, etc.
