“ Llywelyn had no force with which he could withstand so overwhelming a power. He abandoned South Wales in despair, leaving the native chieftains to make what terms they could with the Earl of Lancaster. But he strove, by closely watching the royal advance, and by availing himself of his minute knowledge of the country traversed, to divide, starve out, or dishearten the invaders. A great wood offered a formidable obstacle to the king's advance, but Edward ordered a broad road to be cut through it, and successfully eluded the threatened ambush of Llywelyn. ”
