Sena Gallica.
In a pitched battle the army of the Senones were cut to pieces, and the rest of the tribe expelled from the country; into which the Romans sent the first colony which they ever planted in Gaul—namely, the town of Sena, so called from the tribe of Gauls which formerly occupied it. This is the town which I mentioned before as lying on the coast at the extremity of the plains of the Padus.

20. Seeing the expulsion of the Senones, and fearing the same fate for themselves, the Boii made a general levy, summoned the Etruscans to join them, and set out to war. They mustered their forces near the lacus Vadimonis, and there gave the Romans battle; in which the Etruscans indeed suffered a loss of more than half their men, while scarcely any of the Boii escaped. But yet in the very next year the same two nations joined forces once more; and arming even those of them who had only just reached manhood, gave the Romans battle again; and it was not until they had been utterly defeated in this engagement that they humbled themselves so far as to send ambassadors to Rome and make a treaty.151
These events took place in the third year before Pyrrhus crossed into Italy, and in the fifth before the destruction of the Gauls at Delphi. For at this period fortune seems to have plagued the Gauls with a kind of epidemic of war. But the Romans gained two most important advantages from these events. First, their constant defeats at the hands of the Gauls had inured them to the worst that could befall them; and so, when they had to fight with Pyrrhus, they came to the contest like trained and experienced gladiators. And in the second place, they had crushed the insolence of the Gauls just in time to allow them to give an undivided attention, first to the war with Pyrrhus for the possession of Italy, and then to the war with Carthage for the supremacy in Sicily.

21. After these defeats the Gauls maintained an unbroken peace with Rome for forty-five years. But when the generation which had witnessed the actual struggle had passed away, and a younger generation of men had taken their places, filled with unreflecting hardihood, and who had neither experienced nor seen any suffering or reverse, they began, as was natural, to disturb the settlement; and on the one hand to let trifling causes exasperate them against Rome, and on the other to invite the Alpine Gauls to join the fray. At first these intrigues were carried on by their chiefs without the knowledge of the tribesmen; and accordingly, when an armed host of Transalpine Gauls arrived at Ariminum, the Boii were suspicious; and forming a conspiracy against their own leaders, as well as against the new-comers, they put their own two kings Atis and Galatus to death, and cut each other to pieces in a pitched battle.
B.C. 232.
Just then the Romans, alarmed at the threatened invasion, had despatched an army; but learning that the Gauls had committed this act of self-destruction, it returned home again. In the fifth year after this alarm, in the Consulship of Marcus Aemilius Lepidus, the Romans divided among their citizens the territory of Picenum, from which they had ejected the Senones when they conquered them: a democratic measure introduced by Gaius Flaminius, and a policy which we must pronounce to have been the first step in the demoralisation of the people, as well as the cause of the next Gallic war. For many of the Gauls, and especially the Boii whose lands were coterminous with the Roman territory, entered upon that war from the conviction that the object of Rome in her wars with them was no longer supremacy and empire over them, but their total expulsion and destruction.
B.C. 231.
22. Accordingly the two most extensive tribes, the Insubres and Boii, joined in the despatch of messengers to the tribes living about the Alps and on the Rhone, who from a word which means “serving for hire,” are called Gaesatae. To their kings Concolitanus and Aneroetes they offered a large sum of gold on the spot; and, for the future, pointed out to them the greatness of the wealth of Rome, and all the riches of which they would become possessed, if they took it. In these attempts to inflame their cupidity and induce them to join the expedition against Rome they easily succeeded. For they added to the above arguments pledges of their own alliance; and reminded them of the campaign of their own ancestors in which they had seized Rome itself, and had been masters of all it contained, as well as the city itself, for seven months; and had at last evacuated it of their own free will, and restored it by an act of free grace, returning unconquered and scatheless with the booty to their own land. These arguments made the leaders so eager for the expedition, that there never at any other time came from that part of Gaul a larger host, or one consisting of more notable warriors. Meanwhile, the Romans, informed of what was coming, partly by report and partly by conjecture, were in such a state of constant alarm and excitement, that they hurriedly enrolled legions, collected supplies, and sent out their forces to the frontier, as though the enemy were already in their territory, before the Gauls had stirred from their own lands.
It was this movement of the Gauls that, more than anything else, helped the Carthaginians to consolidate their power in Iberia. For the Romans, as I have said, looked upon the Celtic question as the more pressing one of the two, as being so near home; and were forced to wink at what was going on in Iberia, in their anxiety to settle it satisfactorily first. Having, therefore, put their relations with the Carthaginians on a safe footing by the treaty with Hasdrubal, which I spoke of a short time back,152 they gave an undivided attention to the Celtic war, convinced that their interest demanded that a decisive battle should be fought with them.

23. The Gaesatae, then, having collected their forces, crossed the Alps and descended into the valley of the Padus with a formidable army, furnished with a variety of armour, in the eighth year after the distribution of the lands of Picenum. The Insubres and Boii remained loyal to the agreement they had made with them: but the Venĕti and Cenomani being induced by embassies from Rome to take the Roman side, the Celtic kings were obliged to leave a portion of their forces behind, to guard against an invasion of their territory by those tribes. They themselves, with their main army, consisting of one hundred and fifty thousand foot, and twenty thousand horse and chariots, struck camp and started on their march, which was to be through Etruria, in high spirits. As soon as it was known at Rome that the Celts had crossed the Alps, one of the Consuls, Lucius Aemilius Papus, was sent with an army to Ariminum to guard against the passage of the enemy, and one of the Praetors into Etruria: for the other Consul, Gaius Atilius Regulus, happened to be in Sardinia with his legions. There was universal terror in Rome, for the danger threatening them was believed to be great and formidable. And naturally so: for the old fear of the Gauls had never been eradicated from their minds. No one thought of anything else: they were incessantly occupied in mustering the legions, or enrolling new ones, and in ordering up such of the allies as were ready for service. The proper magistrates were ordered to give in lists of all citizens of military age; that it might at once be known to what the total of the available forces amounted. And such stores of corn, and darts, and other military equipments were collected as no one could remember on any former occasion. From every side assistance was eagerly rendered; for the inhabitants of Italy, in their terror at the Gallic invasion, no longer thought of the matter as a question of alliance with Rome, or of the war as undertaken to support Roman supremacy, but each people regarded it as a danger menacing themselves and their own city and territory. The response to the Roman appeal therefore was prompt.
The Roman resources.
24. But in order that we may learn from actual facts how great the power was which Hannibal subsequently ventured to attack, and what a mighty empire he faced when he succeeded in inflicting upon the Roman people the most severe disasters, I must now state the amount of the forces they could at that time bring into the field. The two Consuls had marched out with four legions, each consisting of five thousand two hundred infantry and three hundred cavalry. Besides this there were with each Consul allies to the number of thirty thousand infantry and two thousand cavalry. Of Sabines and Etruscans too, there had come to Rome, for that special occasion, four thousand horse and more than fifty thousand foot. These were formed into an army and sent in advance into Etruria, under the command of one
