The Romans never desponded in their reverses; they carried the war again into Sicily, and recovered Panormus, the head-quarters of the Carthaginian army. For several years the fleets of the two countries ravaged, one the coast of Africa, the other the Italian shores; in the interior of Sicily the Romans had the advantage; on the coast, the Carthaginians. Twice the fleets of the Republic were destroyed by tempests or by the enemy, and these disasters led the Senate on two occasions to suspend all naval warfare. The struggle remained concentrated during six years in a corner of Sicily: the Romans occupied Panormus; the Carthaginians, Lilybæum and Drepana. It might have been prolonged indefinitely, if the Senate, in spite of the poverty of the treasury, had not succeeded, by means of voluntary gifts, in equipping another fleet of two hundred quinquiremes. Lutatius, who commanded it, dispersed the enemy’s ships near the Ægates, and, master of the sea, threatened to starve the Carthaginians. They sued for peace at the very moment when a great warrior, Hamilcar, had just restored a prestige to their arms. The fact is, that the enormity of her expenses and sacrifices for the last twenty-four years had discouraged Carthage, while at Rome, patriotism, insensible to material losses, maintained the national energy without change. The Carthaginians, obliged to give up all their establishments in Sicily, paid an indemnity of 2,200 talents.[493] From that time the whole island, with the exception of the kingdom of Hiero, became tributary, and, for the first time, Rome had a subject province. If, in spite of this definitive success, there were momentary checks, we must attribute them in great part to the continual changes in the plans of campaign, which varied annually with the generals. Several consuls, nevertheless, were wanting neither in skill nor perseverance, and the Senate, always grateful, gave them worthy recompense for their services. Some obtained the honours of the triumph; among others, Duilius, who gained the first naval battle, and Lutatius, whose victory decided peace. At Carthage, on the contrary, the best generals fell victims to envy and ingratitude. Xanthippus, who vanquished Regulus, was summarily removed through the jealousy of the nobles, whom he had saved;[494] and Hamilcar, calumniated by a rival faction, did not receive from his government the support necessary for the execution of his great designs.
