The Baron of Wortham was indeed surprised at the feebleness of the assault.

The arrows which had fallen in clouds upon the first day's attack upon the castle among his soldiers were now comparatively few and ineffective.

The besiegers scarcely appeared to push forward their bridges with any vigor, and it seemed to him that a coldness had fallen upon them, and that some disagreement must have arisen between the foresters and the earl, completely crippling the energy of the attack.
When he heard the words shouted from the courtyard below he could not believe his ears.

That the keep behind should have been carried by the enemy appeared to him impossible.

With a roar he called upon the bravest of his men to follow, and rushing across the courtyard, rapidly ascended the staircase.
