Brian went to the stables where the three carrier-pigeons were caged, and fetched the cage to the great hall. Here he wrote what had happened, with his plan, in small space, fastened it under the wing of a bird, and let loose the pigeon from the courtyard.
Stunned though he was by the sudden and terrible blow, Brian had seized on the only course left him. If he could make shift to hold the castle at all, he would do so; if not, he must make terms and get off to Gorumna that he might take vengeance for this dastardly stroke that had been dealt him.
Nuala had nigh three hundred men in her castle, and he felt that all was not yet lost, even should he have to yield Bertragh. The Dark Master would hardly have a large force with him, and he would know nothing of those hundred men Brian had loaned Nuala; so Brian reckoned that if he could get away, O'Donnell would think him a broken man who could do no further against him.
"Well, that's looking too far ahead," thought Brian very wearily. "Perchance I am broken, indeed, since I have lost two hundred and a half of men without gain."
An hour later rode in a score of men with wagons, and fell to work getting the dead out of the castle, though for burying there was no time. This score, and two more who came in later, were all the men left to Brian; they reported that the Dark Master would be on them by daybreak, with two hundred Scots troopers and one horse cannon.
"His friends proved niggardly, then," laughed Brian drearily. "We have but to hold the place till to-morrow night, friends, and the O'Malleys will relieve us. Now, one man to watch and the rest of us to rest, for there is work ahead."
Brian, indeed, got some sleep that night, but it was shot through with visions of those poisoned men of his, and their twisted faces gibbered at him, and he thought they shrieked and howled for revenge. When he was roused at dawn, he found the meaning of those noises, since a great storm was sweeping down out of the west, and the farther wore the day, the worse grew the storm.
"Is Heaven itself fighting against us?" he thought bitterly, watching the sea from the battlements. "Against this blast Nuala cannot reach me, if she will."
He got little time to brood, however. Before he had broken his fast the Dark Master's horsemen came in sight—two hundred braw Scots, with wagons and a cannon following after. It was no large force, but Brian found afterward that it was the best the Dark Master could get, since the Galway Irish cared nothing whether the Scots lived or died.
They halted and spread out, half a mile from the castle, and Brian saw that the men were being quartered on the farms round about. Bitterly he wished that he had his lost men, for with them he could have sent those Scots flying home again; but now he was helpless.
