The Gauls, moreover, were terrible on account of their inhuman cruelty, for, wherever they settled, the original towns and their inhabitants completely disappeared from the face of the earth. In their own country they had the feudal system and a priestly government: the Druids were their only rulers, who avenged the oppressed people on the lords, but in their turn became tyrants: all the people were in the condition of serfs, a proof that the Gauls, in their own country too, were the conquerors who had subdued an earlier population. We always find mention of the wealth of the Gauls in gold, and yet France has no rivers that carry gold-sand, and the Pyrenees were then no longer in their possession: the gold must therefore have been obtained by barter. Much may be exaggeration; and the fact of some noble individuals wearing gold chains was probably transferred by ancient poets to the whole nation, since popular poetry takes great liberty, especially in such embellishments.
Pliny states that previous to the Gallic calamity the census amounted to one hundred and fifty thousand persons, which probably refers only to men entitled to vote in the assemblies, and does not comprise women, children, slaves, and strangers. If this be correct, the number of citizens was enormous; but it must not be supposed to include the inhabitants of the city only, the population of which was doubtless much smaller. The statement of Diodorus that all men were called to arms to resist the Gauls, and that the number amounted to forty thousand, is by no means improbable: according to the testimony of Polybius, Latins and Hernicans also were enlisted. Another account makes the Romans take the field against the Gauls with twenty-four thousand men, that is, with four field legions and four civic legions: the field legions were formed only of plebeians, and served, according to the order of the classes, probably in maniples; the civic legions contained all those who belonged neither to the patricians nor to the plebeians, that is, all the aerarii, proletarii, freedmen, and artisans who had never before faced an enemy. They were certainly not armed with the pilum, nor drawn up in maniples; but used pikes and were employed in phalanxes.
Now as for the field legions, each consisted half of Latins and half of Romans, there being in each maniple one century of Roman and one of Latins. There were at that time four legions, and as a legion, including the reserve troops, contained three thousand men, the total is twelve thousand; now the account which mentions twenty-four thousand men must have presumed that there were four field legions and four irregular civic ones. There would accordingly have been no more than six thousand plebeians, and, even if the legions were all made up of Romans, only twelve thousand; if in addition to these we take twelve thousand irregular troops and sixteen thousand allies, the number of forty thousand would be completed. In this case, the population of Rome would not have been as large as that of Athens in the Peloponnesian war, and this is indeed very probable. The cavalry is not included in this calculation: but forty thousand must be taken as the maximum of the whole army. There seems to be no exaggeration in this statement, and the battle on the Alia, speaking generally, is an historical event.
It is surprising that the Romans did not appoint a dictator to command in the battle; it cannot be said indeed that they regarded this war as an ordinary one, for in that case they would not have raised so great a force, but they cannot have comprehended the danger in all its greatness. New swarms continued to come across the Alps; the Senones also now appeared to seek habitations for themselves; they, like the Germans in after-times, demanded land, as they found the Insubrians, Boians, and others already settled; the latter had taken up their abode in Umbria, but only until they should find a more extensive and suitable territory.
The Romans committed the great mistake of fighting with their hurriedly collected troops a battle against an enemy who had hitherto been invincible. The hills along which the right wing is said to have been drawn up are no longer discernible, and they were probably nothing but little mounds of earth: at any rate it was senseless to draw up a long line against the immense mass of enemies. The Gauls, on the other hand, were enabled without any difficulty to turn off to the left. They proceeded to a higher part of the river, where it was more easily fordable, and with great prudence threw themselves with all their force upon the right wing, consisting of the civic legions. The latter at first resisted, but not long; and when they fled, the whole remaining line, which until then seems to have been useless and inactive, was seized with a panic.
Terror preceded the Gauls as they laid waste everything on their way, and this paralyzed the courage of the Romans, instead of rousing them to a desperate resistance. The Romans therefore were defeated on the Alia in the most inglorious manner. The Gauls had taken them in their rear, and cut off their return to Rome. A portion fled toward the Tiber, where some effected a retreat across the river, and others were drowned; another part escaped into a forest. The loss of life must have been prodigious, and it is inconceivable how Livy could have attached so much importance to the mere disgrace. If the Roman army had not been almost annihilated, it would not have been necessary to give up the defence of the city, as was done, for the city was left undefended and deserted by all. Many fled to Veii instead of returning to Rome: only a few, who had escaped along the high road, entered the city by the Colline gate.
Rome was exhausted, her power shattered, her legions defenceless, and her warlike allies had partly been beaten in the same battle, and were partly awaiting the fearful enemy in their own countries. At Rome it was believed that the whole army was destroyed, for nothing was known of those who had reached Veii. In the city itself there were only old men, women, and children, so that there was no possibility of defending it. It is, however, inconceivable that the gates should have been left open, and that the Gauls, from fear of a stratagem, should have encamped for several days outside the gates. A more probable account is that the gates were shut and barricaded. We may form a vivid conception of the condition of Rome after this battle, by comparing it with that of Moscow before the conflagration: the people were convinced that a long defence was impossible, since there was probably a want of provisions.
Livy gives a false notion of the evacuation of the city, as if the defenceless citizens had remained immovable in their consternation, and only a few had been received into the Capitol. The determination, in fact, was to defend the Capitol, and the tribune Sulpicius had taken refuge there, with about one thousand men. There was on the Capitol an ancient well which still exists, and without which the garrison would soon have perished. This well remained unknown to all antiquaries, till I discovered it by means of information gathered from the people who live there. Its depth in the rock descends to the level of the Tiber, but the water is now not fit to drink. The Capitol was a rock which had been hewn steep, and thereby made inaccessible, but a clivus, closed by gates both below and above, led up from the Forum and the Sacred Way. The rock, indeed, was not so steep as in later times, as is clear from the account of the attempt to storm it; but the Capitol was nevertheless very strong. Whether some few remained in the city, as at Moscow, who in their stupefaction did not consider what kind of enemy they had before them, cannot be decided. The narrative is very beautiful, and reminds us of the taking of the Acropolis of Athens by the Persians, where, likewise, the old men allowed themselves to be cut down by the Persians.
Notwithstanding the improbability of the matter, I am inclined to believe that a number of aged patricians—their number may not be exactly historical—sat down in the Forum, in their official robes, on their curule chairs, and that the chief pontiff devoted them to death. Such devotions are a well-known Roman custom. It is certainly not improbable that the Gauls were amazed when they found the city deserted, and only these old men sitting immovable, that they took them for statues or supernatural visions, and did nothing to them, until one of them struck a Gaul who touched him, whereupon all were slaughtered. To commit suicide was repugnant to the customs of the Romans, who were guided in many things by feelings more correct and more resembling our own, than many other ancient nations. The old men, indeed, had given up the hope of their country being saved; but the Capitol might be maintained, and the survivors preferred dying in the attempt of self-defence to taking refuge at Veii, where after all they could not have maintained themselves in the end.
The sacred treasures were removed to Caere, and the hope of the Romans now was that the barbarians would be tired of the long siege. Provisions for a time had been conveyed to the Capitol, where a couple of thousand men may have been assembled, and where all buildings, temples, as well as public and private houses, were used as habitations. The Gauls made fearful havoc at Rome, even more fearful than the Spaniards and Germans did in the year 1527. Soldiers plunder, and when they find no human beings they engage in the work of destruction; and fires break out, as at Moscow, without the existence of any intention to cause a conflagration. The whole city was changed into a heap of ashes, with the exception of a few houses on the Palatine, which were occupied by the leaders of the Gauls. It is astonishing to find, nevertheless, that a few monuments of the preceding period, such as statues, situated at some distance from the Capitol, are mentioned as having been preserved; but we must remember that travertino is tolerably fireproof. That Rome was burned down is certain; and when it was rebuilt, not even the ancient streets were restored.
