A thorough new study by Brian Williams including interpretations of the old Welsh poems, and ancient texts and references have brought a reality to the legends of Arthur and Merlin some of which is found below.

AD 460 saw Ambrosius, the son of the former King “Constantine the Blessed”, return to Britain to claim his inheritance as King of Britain.

He landed at Ketgueli (Kidwelly) and travelled from there through Carmarthen en-route to Dinas Ffaron Dandde ( today's Beddgelert). His purpose was to remove the usurper King Vortigern who had introduced the Angles into 'Britain' and who was based there at this time.

After a number of battles where Vortigern was defeated each time but managed to escape to fight another day, Ambrosius drove him out of Britain
to Brittany in AD 465.

It is important to realise that at this time there were a number of tribes fighting for supremacy mainly the Goedels, Brythons, Angles and Picts. Ambrosius was a Brython, Vortigern was a Goedel and the Angles had been invited in by Vortigern to hold back the invading Picts.

Arthur was born in the midst of all this rivalry in AD 482 at Boverton in the Vale of Glamorgan South Wales and he spent his early years in the area.
He was the son of Meurig the king of Siluria.

Arthur was only 15 when Ambrosius died in battle against Eoppa. Uther and Gereint (Ambrosius’s brother and nephew) were his Regents .with Gereint governing the South and Uther the North of the Kingdom.

In AD 508 Arthur was with Gereint when Gereint's Fleet was attacked at Llongborth (near Chepstow). It would appear that Cerdic, residing at Wroxeter, sailed down the River .Severn and sneaked up on Gereint catching him unawares. Gereint was killed, leaving Arthur in charge in South Cambria.

In AD 512 Uther was killed in battle at Uffington in Shropshire and Arthur assumed the Kingship.
