Another story from Aidan’s period in Wales shows how events of the eleventh and twelfth centuries had an impact upon how Aidan’s story was communicated. It tells how the native Britons of Wales were confronted by the prospect of an invasion by a large Saxon army. Aidan was sent by David to the battlefield and prayed for the Britons, who were outnumbered by their Saxon foes. Following Aidan’s intercession, the Saxons turned and fled and were pursued and slaughtered by the Britons over the following seven days. 

“Not one man of the Britons fell by the hands of the Saxons all that time through the favour of God and the miracles of Maedoc. And no Saxon invaded Britain while Maedoc was there after the manifestation of these miracles”. It is possible that this story was composed at a time when Wales was under threat of invasion by the Normans and can be interpreted as an attempt by the Welsh to warn off potential invaders.
