The two angle-towers had disappeared, tearing away heaps of brick and stone and leaving a mound twenty feet in height. Their destruction had resulted in the removal of the recognized signal to the "Meteor" that all was well.

Even Dacres began to be anxious, although he kept his doubts to himself. The fact of being under fire without being able to return an effective shot told heavily upon the Valderian members of the garrison. He began to consider the possibilities of a retirement.
