XVIII. THE WRATH OF FERGUS MAC ROY.
Reading edition
Barach's banquet was ended. Fergus, anxious and impatient, returned with his people to Emain. And when he found that the sons of Usna had been slain in violation of his pledge, and that his son, Illan the Fair, had fallen while defending them, his grief and wrath knew no bounds. Caffa the druid was none the less incensed; and he was in sore anguish: for he it was, who, trusting in Concobar's deceitful promises, persuaded the sons of Usna to give up their arms and yield. And he pronounced the doom of Concobar's race, that neither he nor any of his descendants should reign in Emain thenceforward for evermore.
And these two, Fergus and Caffa, collecting their men of valour, spoiled and laid waste Concobar's territory; till at last a battle was fought between them, in which the king was defeated, and three hundred of his bravest Ultonians were slain, besides his son and many other illustrious persons in his service. Fergus and Caffa then attacked Emain, and burned and pillaged it, and slew those who defended it. And though the palace was rebuilt in due time, and continued to be the residence of the kings of Ulaid for more than three hundred years afterwards, none of Concobar's descendants possessed it, as Caffa had foretold.
Bronze celts. A celt was a sort of battle axe; sometimes made of bronze, sometimes of stone. The right hand figure shows how the bronze head was fixed to the handle. Great numbers of these celts of many different shapes, both stone and bronze, are preserved in the National Museum, Dublin.

After this, Fergus and other great champions of the Red Branch, with three thousand warriors, marched into Connaught, where Ailell and Maive, king and queen of that province, being at war with Concobar, welcomed them and took them gladly into their service. And for seven years they continued to send marauding parties to spoil and ravage the province of Ulaid, so that many battles were fought, and many heroes were slain. In the stories of this war we read much of the mighty champion Cuculainn who was the chief defender of Ulaid against Ailell and Maive's forces.
