Historical Memory of Irish raids on Britain in Togail Bruidne Dá Derga
In the text, raiders are banished from Ireland by the High King: they resort to raiding across the sea, in Britain. Leaving aside the fact that a High King didn't exist at the time, and that the story supposedly takes place before the birth of Christ, is there any chance the story is vaguely referencing the frequent raids that Goidelic peoples launched from Ireland into western Great Britain in Late Antiquity?
