Brian now turned his attention to the state of religion and literature, restoring the churches and monasteries which had been plundered and burnt by the Danes. He is said also to have founded the churches of Killaloe and Iniscealtra, and to have built the round tower of Tomgrany, in the present county Clare. A gift of twenty ounces of gold to the church of Armagh,—a large donation for that period,—is also recorded amongst his good deeds.[[214]]
There is some question as to the precise year in which Brian obtained or usurped the authority and position of Ard-Righ: A.D. 1002, however, is the date most usually accepted. He was probably about sixty-one years of age, and Malachy was then about fifty-three.[[215]]
It will be remembered that Brian had married the Lady Gormflaith. Her brother, Maelmordha, was King of Leinster, and he had obtained his throne through the assistance of the Danes. Brian was Gormflaith's third husband. In the words of the Annals, she had made three leaps—"jumps which a woman should never jump"—a hint that her matrimonial arrangements had not the sanction of canon law. She was remarkable for her beauty, but her temper was proud and vindictive. This was probably the reason why she was repudiated both by Malachy and Brian. There can be no doubt that she and her brother, Maelmordha, were the remote causes of the famous battle of Clontarf. The story is told thus: Maelmordha came to Brian with an offering of three large pine-trees to make masts for shipping. These were probably a tribute which he was bound to pay to his liege lord. The trees had been cut in the great forest of Leinster, called Fidh-Gaibhli.[[216]] Some other tribes were bringing their tree-tributes at the same time; and as they all journeyed over the mountains together, there was a dispute for precedency. Maelmordha decided the question by assisting to carry the tree of the Ui-Faelain. He had on a tunic of silk which Brian had given[[217]] him, with a border of gold round it and silver buttons. One of the buttons came off as he lifted the tree. On his arrival at Kincora, he asked his sister, Gormflaith, to replace it for him; but she at once flung the garment into the fire, and then bitterly reproached her brother with having accepted this token of vassalage. The Sagas say she was "grim" against Brian, which was undoubtedly true. This excited Maelmordha's temper. An opportunity soon offered for a quarrel. Brian's eldest son, Murrough,[[218]] was playing a game of chess with his cousin, Conoing; Maelmordha was looking on, and suggested a move by which Murrough lost the game. The young prince exclaimed: "That was like the advice you gave the Danes, which lost them Glen-Mama." "I will give them advice now, and they shall not be defeated," replied the other. "Then you had better remind them to prepare a yew-tree[[219]] for your reception," answered Murrough.
Early the next morning Maelmordha left the place, "without permission and without taking leave." Brian sent a messenger after him to pacify him, but the angry chief, for all reply, "broke all the bones in his head." He now proceeded to organize a revolt against Brian, and succeeded. Several of the Irish princes flocked to his standard. An encounter took place in Meath, where they slew Malachy's grandson, Domhnall, who should have been heir if the usual rule of succession had been observed. Malachy marched to the rescue, and defeated the assailants with great slaughter, A.D. 1013. Fierce reprisals now took place on each side. Sanctuary was disregarded, and Malachy called on Brian to assist him. Brian at once complied. After successfully ravaging Ossory he marched to Dublin, where he was joined by Murrough, who had devastated Wicklow, burning, destroying, and carrying off captives, until he reached Cill Maighnenn (Kilmainham). They now blockaded Dublin, where they remained from St. Ciaran's in harvest (Sept. 9th) until Christmas Day. Brian was then obliged to raise the siege and return home for want of provisions.
The storm was now gathering in earnest, and the most active preparations were made on both sides for a mighty and decisive conflict. The Danes had already obtained possession of England, a country which had always been united in its resistance to their power, a country numerically superior to Ireland: why should they not hope to conquer, with at least equal facility, a people who had so many opposing interests, and who rarely sacrificed these interests to the common good? Still they must have had some fear of the result, if we may judge by the magnitude of their preparations. They despatched ambassadors in all directions to obtain reinforcements. Brodir, the earl, and Amlaibh, son of the King of Lochlann, "the two Earls of Cair, and of all the north of Saxon land,"[[220]] came at the head of 2,000 men; "and there was not one villain of that 2,000 who had not polished, strong, triple-plated armour of refined iron, or of cooling, uncorroding brass, encasing their sides and bodies from head to foot." Moreover, the said villains "had no reverence, veneration, or respect, or mercy for God or man, for church or for sanctuary; they were cruel, ferocious, plundering, hard-hearted, wonderful Dannarbrians, selling and hiring themselves for gold and silver, and other treasure as well." Gormflaith was evidently "head centre" on the occasion; for we find wonderful accounts of her zeal and efforts in collecting forces. "Other treasure" may possibly be referred to that lady's heart and hand, of which she appears to have been very liberal on this occasion. She despatched her son, Sitric, to Siguard, Earl of the Orkneys, who promised his assistance, but he required the hand of Gormflaith as payment for his services, and that he should be made King of Ireland. Sitric gave the required promise, and found, on his return to Dublin, that it met with his mother's entire approbation. She then despatched him to the Isle of Man, where there were two Vikings, who had thirty ships, and she desired him to obtain their co-operation "at any price." They were the brothers Ospak and Brodir. The latter demanded the same conditions as the Earl Siguard, which were promised quite as readily by Sitric, only he charged the Viking to keep the agreement secret, and above all not to mention it to Siguard.
Brodir,[[221]] according to the Saga, was an apostate Christian, who had "thrown off his faith, and become God's dastard." He was both tall and strong, and had such long black hair that he tucked it under his belt; he had also the reputation of being a magician. The Viking Ospak refused to fight against "the good King Brian," and, touched by some prodigies, became a convert to Christianity, joined the Irish monarch at Kincora, on the Shannon, and received holy baptism.[[222]] The author of the Wars of the Gaedhil gives a formidable list of the other auxiliaries who were invited by the Dublin Danes. The Annals of Loch Cé also give an account of the fleet he assembled, and its "chosen braves." Maelmordha had mustered a large army also; indeed, he was too near the restless and revengeful Larmflaith to have taken matters quietly, even had he been so inclined.
Meanwhile Brian had been scarcely less successful, and probably not less active. He now marched towards Dublin, "with all that obeyed him of the men of Ireland." These were the provincial troops of Munster and Connaught and the men of Meath. His march is thus described in the Wars of the Gaedhil:—"Brian looked out behind him, and beheld the battle phalanx—compact, huge, disciplined, moving in silence, mutely, bravely, haughtily, unitedly, with one mind, traversing the plain towards them; threescore and ten banners over them—of red, and of yellow, and of green, and of all kinds of colours; together with the everlasting, variegated, lucky, fortunate banner, that had gained the victory in every battle, and in every conflict, and in every combat."[[223]] The portion of the narrative containing this account is believed to be an interpolation, but the description may not be the less accurate. Brian plundered and destroyed as usual on his way to Dublin. When he had encamped near that city, the Danes came out to give him battle on the plain of Magh-n-Ealta.[[224]] The king then held a council of war, and the result, apparently, was a determination to give battle in the morning. It is said that the Northmen pretended flight in order to delay the engagement. The Njal Saga says the Viking Brodir had found out by his sorcery, "that if the fight were on Good Friday, King Brian would fall, but win the day; but if they fought before, they would all fall who were against him." Some authorities also mention a traitor in Brian's camp, who had informed the Danes that his forces had been weakened by the absence of his son Donough, whom he had sent to devastate Leinster. Malachy has the credit of this piece of treachery, with other imputations scarcely less disreputable.
The site of the battle has been accurately defined. It took place on the plain of Clontarf,[[225]] and is called the Battle of the Fishing Weir of Clontarf. The weir was at the mouth of the river Tolka, where the bridge of Ballybough now stands. The Danish line was extended along the coast, and protected at sea by their fleets. It was disposed in three divisions, and comprised about 21,000 men, the Leinster forces being included in the number. The first division or left wing was the nearest to Dublin. It was composed of the Danes of Dublin, and headed by Sitric, who was supported by the thousand mail-clad Norwegians, commanded by Carlus and Anrud. In the centre were the Lagennians, under the command of Maelmordha. The right wing comprised the foreign auxiliaries, under the command of Brodir and Siguard.[[226]]
Brian's army was also disposed in three divisions. The first was composed of his brave Dalcassians, and commanded by his son Murrough, assisted by his four brothers, Teigue, Donough, Connor, and Flann, and his youthful heir, Turlough, who perished on the field. The second division or centre was composed of troops from Munster, and was commanded by Mothla, grandson of the King of the Deisi, of Waterford, assisted by many native princes. The third battalion was commanded by Maelruanaidh (Mulrooney of the Paternosters) and Teigue O'Kelly, with all the nobles of Connaught. Brian's army numbered about twenty thousand men. The accounts which relate the position of Malachy, and his conduct on this occasion, are hopelessly conflicting. It appears quite impossible to decide whether he was a victim to prejudice, or whether Brian was a victim to his not unnatural hostility.
On the eve of the battle, one of the Danish chiefs, Plait, son of King Lochlainn, sent a challenge to Domhnall, son of Emhin, High Steward of Mar. The battle commenced at daybreak. Plait came forth and exclaimed three times, "Faras Domhnall?" (Where is Domhnall?) Domhnall replied: "Here, thou reptile." A terrible hand-to-hand combat ensued. They fell dead at the same moment, the sword of each through the heart of the other, and the hair of each in the clenched hand of the other. And the combat of those two was the first combat of the battle.
