Page "Ambrosius Aurelianus" Paragraph 8

But there are smaller snippets of tradition preserved in the Historia Brittonum: in Chapter 31, we are told that Vortigern ruled in fear of Ambrosius ; later, in Chapter 66, various events are dated from a Battle of Guoloph ( often identified with Wallop, ESE of Amesbury near Salisbury ), which is said to have been between Ambrosius and Vitolinus ; lastly, in Chapter 48, it is said that Pascent, the son of Vortigern, was granted rule over the regions of Buellt and Gwrtheyrnion by Ambrosius.

It is not clear how these various traditions relate to each other, or whether they come from the same tradition ; it is very possible that these references are to different men with the same name.

The Historia Brittonum dates the battle of Guoloph to " the twelfth year of Vortigern ", by which 437 seems to be meant.

This is perhaps a generation before the battle that Gildas says were commanded by Ambrosius Aurelianus.
