day dawned the Romans discovered what had happened, and indeed for a short time were engaged with Hannibal’s rear; but eventually they all made for the town gates. There they found no one to oppose them: they therefore threw themselves into the town, plundered it, and secured a large number of captives, besides a great booty of every sort and description. [Sidenote: This success inspires the Senate with the idea of expelling the Carthaginians from Sicily.] [Sidenote: B.C. 261.] +20.+ Great was the joy of the Roman Senate when the news of what had taken place at Agrigentum arrived. Their ideas too were so raised that they no longer confined themselves to their original designs. They were not content with having saved the Mamertines, nor with the advantages gained in the course of the war; but conceived the idea that it was possible to expel the Carthaginians entirely from the island, and that if that were done their own power would receive a great increase: they accordingly engaged in this policy and directed their whole thoughts to this subject. As to their land forces they saw that things were going on as well as they could wish. For the Consuls elected in succession to those who had besieged Agrigentum, Lucius Valerius Flaccus and Titus Otacilius Crassus, appeared to be managing the Sicilian business as well as circumstances admitted. Yet so long as the Carthaginians were in undisturbed command of the sea, the balance of success could not incline decisively in their favour. For instance, in the period which followed, though they were now in possession of Agrigentum, and though consequently many of the inland towns joined the Romans from dread of their land forces, yet a still larger number of seaboard towns held aloof from them in terror of the Carthaginian fleet. Seeing therefore that it was ever more and more the case that the balance of success oscillated from one side to the other from these causes; and, moreover, that while Italy was repeatedly ravaged by the naval force, Libya remained permanently uninjured; they became eager to get upon the sea and meet the Carthaginians there. It was this branch of the subject that more than anything else induced me to give an account of this war at somewhat greater length than I otherwise should have done. I was unwilling that a first step of this kind should be unknown,—namely how, and when, and why the Romans first started a navy.
