This opinion having been approved of by unanimous consent, more than twenty towns of the Bituriges are burned in one day. Conflagrations are beheld in every quarter; and although all bore this with great regret, yet they laid before themselves this consolation, that, as the victory was certain, they could quickly recover their losses. There is a debate concerning Avaricum in the general council, whether they should decide, that it should be burned or defended. The Bituriges threw themselves at the feet of all the Gauls, and entreat that they should not be compelled to set fire with their own hands to the fairest city of almost the whole of Gaul, which was both a protection and ornament to the state; they say that "they could easily defend it, owing to the nature of the ground, for, being inclosed almost on every side by a river and a marsh, it had only one entrance, and that very narrow." Permission being granted to them at their earnest request, Vercingetorix at first dissuades them from it, but afterward concedes the point, owing to their entreaties and the compassion of the soldiers. A proper garrison is selected for the town.

Vercingetorix follows closely upon Caesar by shorter marches, and selects for his camp a place defended by woods and marshes, at the distance of fifteen miles from Avaricum . There he received intelligence by trusty scouts, every hour in the day, of what was going on at Avaricum , and ordered whatever he wished to be done; he closely watched all our expeditions for corn and forage, and whenever they were compelled to go to a greater distance, he attacked them when dispersed, and inflicted severe loss upon them; although the evil was remedied by our men, as far as precautions could be taken, by going forth at irregular times' and by different ways.

Caesar pitching his camp at that side of the town which was not defended by the river and marsh, and had a very narrow approach, as we have mentioned, began to raise the vineae and erect two towers: for the nature of the place prevented him from drawing a line of circumvallation. He never ceased to importune the Boii and Aedui for supplies of corn; of whom the one [the Aedui], because they were acting with no zeal, did not aid him much; the others [the Boii], as their resources were not great, quickly consumed what they had. Although the army was distressed by the greatest want of corn, through the poverty of the Boii, the apathy of the Aedui, and the burning of the houses, to such a degree, that for several days the soldiers were without corn, and satisfied their extreme hunger with cattle driven from the remote villages; yet no language was heard from them unworthy of the majesty of the Roman people and their former victories. Moreover, when Caesar addressed the legions, one by one, when at work, and said that he would raise the siege, if they felt the scarcity too severely, they unanimously begged him "not to do so; that they had served for several years under his command in such a manner that they never submitted to insult, and never abandoned an enterprise without accomplishing it; that they should consider it a disgrace if they abandoned the siege after commencing it; that it was better to endure every hardship than to not avenge the names of the Roman citizens who perished at Genabum by the perfidy of the Gauls." They intrusted the same declarations to the centurions and military tribunes, that through them they might be communicated to Caesar.

When the towers had now approached the walls, Caesar ascertained from the captives that Vercingetorix after destroying the forage, had pitched his camp nearer Avaricum , and that he himself with the cavalry and light-armed infantry, who generally fought among the horse, had gone to lay an ambuscade in that quarter, to which he thought that our troops would come the next day to forage. On learning these facts, he set out from the camp secretly at midnight, and reached the camp of the enemy early in the morning. They having quickly learned the arrival of Caesar by scouts, hid their cars and baggage in the thickest parts of the woods, and drew up all their forces in a lofty and open space: which circumstance being announced, Caesar immediately ordered the baggage to be piled, and the arms to be got ready.
