To the extraordinary valour of our soldiers, devices of every sort were opposed by the Gauls; since they are a nation of consummate ingenuity, and most skilful in imitating and making those things which are imparted by anyone; for they turned aside the hooks with nooses, and when they had caught hold of them firmly, drew them on by means of engines, and undermined the mound the more skilfully on this account, because there are in their territories extensive iron mines, and consequently every description of mining operations is known and practised by them. They had furnished, moreover, the whole wall on every side with turrets, and had covered them with skins. Besides, in their frequent sallies by day and night, they attempted either to set fire to the mound, or attack our soldiers when engaged in the works; and, moreover, by splicing the upright timbers of their own towers, they equalled the height of ours, as fast as the mound had daily raised them, and countermined our mines, and impeded the working of them by stakes bent and sharpened at the ends, and boiling pitch, and stones of very great weight, and prevented them from approaching the walls.
But this is usually the form of all the Gallic walls. Straight beams, connected lengthwise and two feet distant from each other at equal intervals, are placed together on the ground; these are mortised on the inside, and covered with plenty of earth. But the intervals which we have mentioned, are closed up in front by large stones. These being thus laid and cemented together, another row is added above, in such a manner that the same interval may be observed, and that the beams may not touch one another, but equal spaces intervening, each row of beams is kept firmly in its place by a row of stones. In this manner the whole wall is consolidated, until the regular height of the wall be completed. This work, with respect to appearance and variety, is not unsightly, owing to the alternate rows of beams and stones, which preserve their order in right lines; and, besides, it possesses great advantages as regards utility and the defence of cities; for the stone protects it from fire, and the wood from the battering ram, since it [the wood] being mortised in the inside with rows of beams, generally forty feet each in length, can neither be broken through nor torn asunder.
The siege having been impeded by so many disadvantages, the soldiers, although they were retarded during the whole time, by the mud, cold, and constant showers, yet by their incessant labour overcame all these obstacles, and in twenty-five days raised a mound three hundred and thirty feet broad and eighty feet high. When it almost touched the enemy’s walls, and Caesar, according to his usual custom, kept watch at the work, and encouraged the soldiers not to discontinue the work for a moment: a little before the third watch they discovered that the mound was sinking, since the enemy had set it on fire by a mine; and at the same time a shout was raised along the entire wall, and a sally was made from two gates on each side of the turrets. Some at a distance were casting torches and dry wood from the wall on the mound, others were pouring on it pitch, and other materials, by which the flame might be excited, so that a plan could hardly be formed, as to where they should first run to the defence, or to what part aid should be brought. However, as two legions always kept guard before the camp by Caesar’s orders, and several of them were at stated times at the work, measures were promptly taken, that some should oppose the sallying party, others draw back the towers and make a cut in the rampart; and moreover, that the whole army should hasten from the camp to extinguish the flames.
When the battle was going on in every direction, the rest of the night being now spent, and fresh hopes of victory always arose before the enemy: the more so on this account because they saw the coverings of our towers burnt away, and perceived that we, being exposed, could not easily go to give assistance, and they themselves were always relieving the weary with fresh men, and considered that all the safety of Gaul rested on this crisis; there happened in my own view a circumstance which, having appeared to be worthy of record, we thought it ought not to be omitted. A certain Gaul before the gate of the town, who was casting into the fire opposite the turret balls of tallow and fire which were passed along to him, was pierced with a dart on the right side and fell dead. One of those next him stepped over him as he lay, and discharged the same office: when the second man was slain in the same manner by a wound from a crossbow, a third succeeded him, and a fourth succeeded the third: nor was this post left vacant by the besieged, until, the fire of the mound having been extinguished, and the enemy repulsed in every direction, an end was put to the fighting.
The Gauls having tried every expedient, as nothing had succeeded, adopted the design of fleeing from
