The battle at first went decidedly against the assailants. The Count had left behind him a catapult among other effects which he had not thought it worth while to remove; and Martianus, who had practised some of the garrison in the use of it, brought it into play with considerable effect. The very first discharge killed one of the lesser chiefs, and a little later in the day Ambiorix himself was badly bruised by one of the stones propelled from it. Meanwhile the defenders escaped almost wholly without injury. There was no need for them to leave the shelter of the buildings. As long as they kept within this the bows and slings of the enemy failed to harm them. One or two rash young recruits exposed themselves unnecessarily, and were wounded in consequence; but when Ambiorix, about an hour before sunset, called off his men, the garrison found that the casualties had been very slight and few. During the night the besiegers were not idle. They constructed a mantelet(61) of wicker work covered with stout hides, and brought it out close to the palisade—an operation which the besieged, with a culpable carelessness, allowed them to do unmolested. From under cover of this they plied long poles, armed at the ends with blades of steel (for Ambiorix was not so obstinate a conservative as to go back to the axe of bronze), and hacked away at the palisade. The catapult produced no effect on this erection, and though arrows, discharged almost perpendicularly into the air so as to fall just on the other side of it, inflicted some injury, the work went on without interruption. Martianus, seeing this, headed a sally in person, and, after a sharp struggle, succeeded in possessing himself of it. The wicker work was broken in pieces, and the hides carried off within the line of defences. The next three days passed without incident, and the inmates of the villa began to hope that the danger had passed over. In reality, however, the besiegers were collecting materials for the construction of another mantelet on a much larger scale. As much of this as was possible was put together out of sight of the villa, and on the morning of the fourth day an erection of considerable size could be seen about fifty yards from the palisade. It soon became evident that the new plan of the assailants was to try the effect of fire. Arrows were wrapped round with tow, and, when this had been lighted, were discharged into the enclosure. Some mischief was done, not so much to the buildings, for it was not difficult to put out the fire if the arrows happened to fall on an inflammable place, but to the garrison. The men who had to extinguish the flames could not avoid exposing themselves, and those who exposed themselves were frequently hit by the slingers and archers. On the whole, however, little progress was made, and when, in the course of the evening, a heavy rain came on, and the wind, which had hitherto assisted the flames, altogether died away, the discharge ceased.
