Gallic War

The whole multitude raise a shout and clash their arms, according to their custom, as they usually do in the case of him of whose speech they approve; [they exclaim] that Vercingetorix was a consummate general, and that they had no doubt of his honor; that the war could not be conducted with greater prudence. They determine that ten thousand men should be picked out of the entire army and sent into the town, and decide that the general safety should not be intrusted to the Bituriges alone, because they were aware that the glory of the victory must rest with the Bituriges, if they made good the defense of the town.

To the extraordinary valor of our soldiers, devices of every sort were opposed by the Gauls; since they are a nation of consummate ingenuity, and most skillful in imitating and making those things which are imparted by any one; 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 skillfully on this account, because there are in their territories extensive iron mines, and consequently every description of mining operations is known and practiced by them. They had furnished, more over, 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 equaled 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 defense 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 labor 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 defense, 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.
