Turlough picked a hollow in the road a mile farther from the castle, flanked on either hand by woods and hillsides where men might lie hidden. Brian found it good, and that afternoon a part of their horsemen were shifted thither in readiness.
For the next three days there was little done. Twice the Dark Master attempted sallies with what few horsemen he had left, but on each occasion Cathbarr's horse smote his men and drove them back. To be sure, O'Donnell thundered with his bastards, but the guns only burned up good powder, for Brian would allow no assault made.
By Turlough's advice, however, they brought about the Dark Master's fall through certain prisoners made in the two sallies.
These captives were led through the depleted central camp, though they knew nothing of that picked place farther back. Having been allowed to see what men Brian had here, Turlough slyly drove Cathbarr into parading his vanity before them; and in all innocence the giant told how he could put the Dark Master's men to flight single-handed, and of his anxiety lest the O'Donnells should fear to fight in the open. What was more, Brian affected to be utterly shattered by his wounds, and with that the prisoners were sent back with a message offering quarter to all within the castle save the Dark Master himself.
Early the next morning a horseman came riding fast from Cathbarr with word that the garrison was stirring. Without delay, Brian donned a mail-shirt, bound his useless left arm to his side, and mounted. The Bird Daughter insisted on accompanying him, and stilled his dismayed protests by asserting her feudal superiority; in the end she had her way.
Leaving her kinsmen and a hundred more men to dispute O'Donnell's passage and give back slowly before him with Cathbarr, she and Brian rode to their men among the trees on the hillsides over the hollow in the road. Here they had a hundred and fifty men, composed of the Scots troopers and the pick of the others, and Nuala took one side of the road while Brian took the other. Then, being well hidden, they waited.
Brian was savagely determined to slay the Dark Master that day, and came near to doing it. Presently a man galloped up to say that O'Donnell and six hundred men were on the road, having left the rest to hold the castle. A little later Cathbarr's retreating force came in sight, and after them marched O'Donnell. He had deployed his muskets in front and rear, and rode in the midst of his pikemen, whose banner of England blew out bravely in the morning wind.
At the edge of the dip in the road Cathbarr led his men in full flight down the hollow and up the farther rise, where he halted as if to dispute the Dark Master further. There were barely a dozen mounted men with O'Donnell, and he made no pursuit, but marched steadily along with his muskets pecking at Cathbarr's men. When he had come between the wooded hillsides, however, Cathbarr came charging down the road; the pikemen settled their pikes three deep to receive him, and with that Brian led out his men among the trees and swooped down with an ax swinging in his right hand.
Alive to his danger, the Dark Master tried to receive his charge, but at that instant Nuala's men burst down on the other flank. Brian headed his men, and at sight of him a yell of dismay went up from the O'Donnells. A moment later the pikemen's array was broken and the fight disintegrated into a wild affray wherein the horsemen had much the better of it.
