Aedh, Prince of Connaught, the father of the lad who had been so cruelly put to death, was already preparing for vengeance. The chiefs of Tir-Connell joined him, hot in Columba's cause. The men who gathered to avenge the insult made a formidable army, and Diarmaid on his side lost no time in gathering his forces for battle. The encounter took place at Cuil-dreimhne, between Balbulbin Mountain and the sea, and the fight was long and bloody. Columba, say some of the old writers, was himself present, and prayed with outstretched arms for the victory of his people. Three thousand of Diarmaid's men fell on the field of battle, while the losses of the Hy-Nialls of the north, such was the efficacy of the prayers of Columbcille, were comparatively slight. The victory was complete, but Diarmaid was not the man to take his defeat meekly. He appealed to the Church to judge the conduct of Columba. Did it seem right and good, he asked, that a priest and an abbot, the founder of religious houses, and one who had dedicated his life to the service of Christ, should have provoked a bloody war which had been the death of thousands of innocent men? The churchmen looked grave. The case thus stated did not promise well for Columba. He was the friend of all: the zeal and fervour of his life, the charity and generosity of his heart were known throughout the length and breadth of Erin. There was but one weak point in that noble nature--the haughty spirit that had come to him with the hot blood of the Hy-Nialls; and certainly he had been sorely tried by circumstances. Yet--the fact was incontestable--his conduct as an abbot and as a priest was open to the gravest censure. He was ordered to appear before an ecclesiastical council which was summoned to meet at Teilte in the heart of the King's domains to hear the judgment that should be pronounced upon him by the Saints of Erin. CHAPTER V A BITTER PENANCE MANY of the holiest men in Ireland were present at the Synod of Teilte. St. Enda of Aran had passed from his life of penance to the glory which is eternal; but St. Brendan of Birr, and probably his namesake the Bishop of Clonfert, with his assistant St. Moinen, Oena of Clonmacnoise, successor of the saintly Ciaran, and St. Kevin of Glendalough, formed part of the Council. When Columba was seen approaching in the distance, St. Brendan of Birr alone arose and went forward to receive him. The Fathers objected to his action. It was not fitting, they said, that one who was under the grave censure of the Church should be greeted with marks of deference and honour. "If you saw what I see," replied the holy Brendan, "you would hasten to do likewise. I see Columba, as he climbs the hill, surrounded by a column of light, and angels going before and after him. I bow before the Hand of God which destines him to convert a whole nation to the faith of Christ."
