The mass of men gained the moat before a challenge rang out from above, and with that Brian leaped forward at the gates. A musket roared out, and another, but Brian and Cathbarr were in the courtyard before the Scots awakened. A startled group barred their way to the hall, then Brian thrust once, the huge ax crashed down, and they were through.

Other men were sleeping in the hall, but Brian did not stop to battle here, running through before the half-awakened figures sensed what was forward. A great din of clashing steel and yells was rising from the court; then he and Cathbarr gained the seaward battlements and rushed at the Dark Master's chamber. The door was open—it was empty.

For a moment the two stared at each other in blank dismay. With a yell, a half-dozen Scots swirled down on them, but Brian threw up his hand.

"The castle is mine," he shouted. "You shall have quarter!"

The Scots halted, and when two or three of the Kerry pikemen dashed up with news that the rest of the garrison had been cut down or given quarter, they surrendered.

Brian's first question was as to O'Donnell.

"Either at the camp or aboard one of his kinsmen's ships," returned one of the prisoners. "They were carousing all last evening."

At the same instant Cathbarr caught Brian's arm and whirled him about.

"Listen, brother!"

So swift had been Brian's attack that the castle had been won in a scant three minutes. Now, as he listened, there came a ragged roar of musketry, pierced by yells, and he knew that the camp was attacked.
