Methinks that the Kerr's hold may more easily be made to withstand a lengthened siege than Glen Cairn, seeing that the latter is commanded by the hill beside it.
Kerr's castle, too, is much larger and more strongly fortified.

I need no thanks," he continued, as Archie was about to express his warm gratitude; "it is the Warden of Scotland who rewards your services to the country; but Sir William Wallace will not forget how you have twice stood beside him against overwhelming odds, and how yesterday, in Stirling, it was your watchful care and thoughtful precaution which alone saved his life." Archie's friends all congratulated him warmly, and the next morning, with his own band, he started for Glen Cairn.

Here the news that he was once more their lawful chief caused the greatest delight.
It was evening when he reached the village, and soon great bonfires blazed in the street, and as the news spread burned up from many an outlying farm.

Before night all the vassals of the estate came in, and Glen Cairn and the village was a scene of great enthusiasm.
Much as Archie regretted that he could not establish himself in the hold of his father, he felt that Wallace's suggestion was the right one.

Glen Cairn was a mere shell, and could in no case be made capable of a prolonged resistance by a powerful force.
