St.Germanus arrived in the island to fight the Pelagian heresy, which had spread to the region. He spoke of a rich land, although it was at war. They were being invaded from either the north or the east, by an army of Saxons, Picts and Scots. St. Germanus had been a general beforehand and gathered an army to fight the oncoming horde. He had the soldiers hide, waiting in ambush. When the army was coming, he had the priest shout a "triple Alleluia" and the sound echoed through the valley, terrifying the heathens, who ran for their lives.
