9. With great rapidity they built some wooden towers, higher than the battlements of the enemy, and then fastening their boats together, they placed these towers on them. In them they stationed soldiers, who, with undaunted resolution, laboured to drive down the garrison from the walls; while under them were bodies of light infantry wholly unencumbered, who going forth from the hollow parts of the towers below, threw drawbridges across, which they had put together beforehand, and so tried to cross over to the bottom of the wall while the attention of the garrison was diverted from them; so that while those above them were attacking one another with darts and stones, those who crossed over on the drawbridges might be able without interruption to break down a portion of the wall and so effect an entrance. 10. But once more a clever design failed in its result. For when the towers came close to the walls, they were assailed with brands steeped in pitch, and reeds, and faggots, and every kind of food for flames, all kindled. The towers quickly caught fire, and yielding under the weight of the men who were mounted on them, fell into the river, while some of the soldiers on their summits, even before they fell, had been pierced with javelins hurled from the engines on the walls, and so died. 11. Meanwhile the soldiers at the foot of the wall, being cut off by the destruction of their comrades in the boats, were crushed with huge stones, with the exception of a few, who, in spite of the difficult ground over which their flight lay, escaped by their swiftness of foot. At last, when the contest had been protracted till evening, the usual signal for retreat was given, and the combatants parted to pass the night with very different feelings. 12. The losses of the besiegers, who had suffered greatly, encouraged the defenders of the town with hopes of victory, though they also had to mourn the deaths of some few of their number. Nevertheless, the preparations went on rapidly. Rest and food refreshed their bodies during the night; and at dawn of day the conflict was renewed at the trumpet's signal. 13. Some, holding their shields over their heads, in order to fight with more activity; others, in front, bore ladders on their shoulders, and rushed on with eager vehemence, exposing their breasts to wounds from every kind of weapon. Some endeavoured to break down the iron bars of the gates; but were attacked with fire, or crushed under stones hurled from the walls. Some boldly strove to cross the fosses, but fell beneath the sudden sallies of soldiers rushing out from postern gates, or were driven back with severe wounds. For those who sallied forth had an easy retreat within the walls, and the rampart in front of the walls, strengthened with turf, saved those who lay in wait behind it from all danger.
