All this, however, required time. For once the Romans had allowed themselves to be surprised, and it was too late at least to save Etruria. The Celts found the Apennines hardly defended, and plundered unopposed the rich plains of the Tuscan territory, which for long had seen no enemy. They were already at Clusium, three days' march from Rome, when the army of Ariminum, under the consul Papus, appeared on their flank, while the Etruscan militia, which after crossing the Apennines had assembled in rear of the Gauls, followed the line of the enemy's march. Suddenly one evening, after the two armies had already encamped and the bivouac fires were kindled, the Celtic infantry again broke up and retreated on the road towards Faesulae (Fiesole): the cavalry occupied the advanced posts during the night, and followed the main force next morning. When the Tuscan militia, who had pitched their camp close upon the enemy, became aware of his departure, they imagined that the host had begun to disperse, and marched hastily in pursuit. The Gauls had reckoned on this very result: their infantry, which had rested and was drawn up in order, awaited on a well-chosen battlefield the Roman militia, which came up from its forced march fatigued and disordered. Six thousand men fell after a furious combat, and the rest of the militia, which had been compelled to seek refuge on a hill, would have perished, had not the consular army appeared just in time. This induced the Gauls to return homeward. Their dexterously-contrived plan for preventing the union of the two Roman armies and annihilating the weaker in detail, had only been partially successful; now it seemed to them advisable first of all to place in security their considerable booty. For the sake of an easier line of march they proceeded from the district of Chiusi, where they were, to the level coast, and were marching along the shore, when they found an unexpected obstacle in the way. It was the Sardinian legions, which had landed at Pisae; and, when they arrived too late to obstruct the passage of the Apennines, had immediately put themselves in motion and were advancing along the coast in a direction opposite to the march of the Gauls. Near Telamon (at the mouth of the Ombrone) they met with the enemy. While the Roman infantry advanced with close front along the great road, the cavalry, led by the consul Gaius Atilius Regulus in person, made a side movement so as to take the Gauls in flank, and to acquaint the other Roman army under Papus as soon as possible with their arrival. A hot cavalry engagement took place, in which along with many brave Romans Regulus fell; but he had not sacrificed his life in vain: his object was gained. Papus became aware of the conflict, and guessed how matters stood; he hastily arrayed his legions, and on both sides the Celtic host was now pressed by Roman legions. Courageously it made its dispositions for the
