Chapter VII: Prophecy of the blessed man regarding the Tumults of Battles fought at a distance
About two years, as we have been told, after the battle of Cule-Drebene (in Connaught), at which time the blessed man first set sail and took his departure from Scotia (Ireland), it happened that on the very day and at the same hour when the battle, called in Scotic Ondemone (near Coleraine), was fought in Scotia (Ireland), the same man of God was then living in Britain with King Connall, the son of Comgell, and told him everything, as well about the battle itself, as also about those kings to whom the Lord granted the victory over their enemies. These kings were known as Ainmore, son of Setna, and the two sons of Mac Erca, Domnall and Forcus. And the saint, in like manner, prophesied of the king of the Cruithne, who was called Echoid Laib, and how, after being defeated, he escaped riding in his chariot.

On the Battle of the Miathi

At another time, after the lapse of many years from the above-mentioned battle, and while the holy man was in the Iouan island (Hy, now Iona), he suddenly said to his minister, Diormit, "Ring the bell." The brethren, startled at the sound, proceeded quickly to the church, with the holy prelate himself at their head. There he began, on bended knees, to say to them, "Let us pray now earnestly to the Lord for this people and King Aidan, for they are engaging in battle at this moment." Then after a short time he went out of the oratory, and, looking up to heaven, said, "The barbarians are fleeing now, and to Aidan is given the victory, a sad one though it be." And the blessed man in his prophecy declared the number of the slain in Aidan's army to be three hundred and three men.
