If that great warrior heard, how he must have grinned! The besiegers encamped a furlong from the walls, and made roads; kept their pikemen in camp ready for an assault when practicable; and sent forward their sappers, pioneers, catapultiers, and crossbowmen. These opened a siege by filling the moat, and mining, or breaching the wall, etc. And as much of their work had to be done under close fire of arrows, quarels, bolts, stones, and little rocks, the above artists “had need of a hundred eyes,” and acted in concert with a vigilance, and an amount of individual intelligence, daring, and skill, that made a siege very interesting, and even amusing: to lookers on. The first thing they did was to advance their carpenters behind rolling mantelets, to erect a stockade high and strong on the very edge of the moat. Some lives were lost at this, but not many; for a strong force of crossbowmen, including Denys, rolled their mantelets up and shot over the workmen's heads at every besieged who showed his nose, and at every loophole, arrow-slit, or other aperture, which commanded the particular spot the carpenters happened to be upon. Covered by their condensed fire, these soon raised a high palisade between them and the ordinary missiles from the pierced masonry. But the besieged expected this, and ran out at night their boards or wooden penthouses on the top of the curtains. The curtains were built with square holes near the top to receive the beams that supported these structures, the true defence of mediaeval forts, from which the besieged delivered their missiles with far more freedom and variety of range than they could shoot through the oblique but immovable loopholes of the curtain, or even through the sloping crenelets of the higher towers. On this the besiegers brought up mangonels, and set them hurling huge stones at these woodworks and battering them to pieces. Contemporaneously they built a triangular wooden tower as high as the curtain, and kept it ready for use, and just out of shot. This was a terrible sight to the besieged. These wooden towers had taken many a town. They began to mine underneath that part of the moat the tower stood frowning at; and made other preparations to give it a warm reception. The besiegers also mined, but at another part, their object being to get under the square barbican and throw it down. All this time Denys was behind his mantelet with another arbalestrier, protecting the workmen and making some excellent shots. These ended by earning him the esteem of an unseen archer, who every now and then sent a winged compliment quivering into his mantelet. One came and struck within an inch of the narrow slit through which Denys was squinting at the moment. “Peste,” cried he, “you shoot well, my friend. Come forth and receive my congratulations! Shall merit such as thine hide its head? Comrade, it is one of those cursed Englishmen, with his half ell shaft. I'll not die till I've had a shot at London wall.”
