We lost no time in falling in with Granville's suggestion, and immediately after we set the men to work on constructing thick wooden mantlets, under the cover of which we still further repaired the breach in the walls.

Unfortunately, a great part of the dislodged masonry had fallen outwards, almost filling in the moat immediately in front of the weakest part of our defences; but behind the breach we built up a second wall, breast high, backed by a platform of earth, so that we could the better hold our own in a chance hand-to-hand conflict.

Barely had we completed these preparations when there came the deep boom of a cannon. The rebels had unspiked their sole remaining piece of ordnance, and were renewing the attack.

The first shot, being totally unexpected, was particularly disastrous, for three men were struck down, two being killed outright, and one grievously wounded.

While the cannonade lasted, we, as before, could do nothing, but presently we observed the pikemen and musketeers massing in solid ranks, slightly to the left of the line of fire of the cannon. Then two dismounted officers made their way to the front, and took a long and careful look at our defences.

"There's Chaloner!" I exclaimed, pointing to one of the pair, who were clad in complete breast and back pieces over their buff coats, and wore steel motions protected by guards. These accoutrements were not worn by the dragoons, and Granville remarked about the fact.

"'Tis certain the rogue makes himself secure from pike-thrusts," he remarked, with a scornful laugh.

The rebel ranks were set in motion, and, with matches lighted and pikeheads gleaming in the sunlight, they advanced to the attack, the pikemen in the centre and the musketeers on either flank.

So intent were we on the oncoming danger that we almost failed to notice a solitary horseman riding furiously down the hill-side from the clump of trees, from which he had emerged.

Spurring towards the deserted trenches, his horse cleared them at a single bound, and ere either we or the rebels could grasp the meaning of it, the rider was halfway across the intervening ground.
