I shall walk round the ground, and see that all are vigilant.

We know not where Glendower's men were lying.

It may hap they were twenty miles away, but even so he would have had plenty of time to have brought them up, by now.

I don't think there is much chance of any of our men being surprised; most of them having, in their time, been so used to midnight rides across moor and hill, and so accustomed to see in the dark that, crafty as the Welshmen may be, I do not think there is a chance of their getting within a hundred yards of any of our posts, without being seen; especially as the moon is still half full." "Do you think that there is any chance of our being disturbed, Master Oswald ?" Roger said, as they took up their post under a low, stunted tree.
"I do not think so.

If Glendower's spies have told him that the main body, of those who surprised him this morning, have returned to Chirk; he may be sure that enough have been left, to hold the place successfully against him and his wild followers, till assistance can reach us; and he would have nothing to gain by recapturing his house, for he could not hold it long against the force assembled at Chirk.
Besides, he must know, well enough, that if he is to fight successfully, it must be in the woods.
