The Romans now determined to push the war vigorously, and began the siege of Lilybæum (now Marsala), which was the only place besides Drepanum, fifteen miles distant, yet remaining to the enemy on the island of Sicily (B.C. 250). It was not until the end of the war that the Carthaginians could be forced from these two strongholds. Six years before that time (B.C. 247), there came to the head of Carthaginian affairs a man of real greatness, Hamilcar Barca, whose last name is said to mean lightning; but even he was not strong enough to overcome the difficulties caused by the faults of others, and in 241 he counselled peace, which was accordingly concluded, though Carthage was obliged to pay an enormous indemnity, and to give up her claim to Sicily, which became a part of the Roman dominion (the first "province" so-called), governed by an officer annually sent from Rome. Hamilcar had at first established himself on Mount Ercte, overhanging Panormus, whence he made constant descents upon the enemy, ravaging the coast as far as Mount Ætna. Suddenly he quitted this place and occupied Mount Eryx, another height, overlooking Drepanum, where he supported himself two years longer, and the Romans despaired of dislodging him. In their extremity, they twice resorted to the navy, and at last, with a fleet of two hundred ships, defeated the Carthaginians off the Ægusæ Islands, to the west of Sicily, and as the resources of Hamilcar were then cut off, it was only a question of time when the armies at Eryx, Drepanum, and Lilybæum would be reduced by famine. It was in view of this fact that the settlement was effected. A period of peace followed this long war, during which at one time, in the year 235, the gates of the temple of Janus, which were always open during war and had not been shut since the days of Numa, were closed, but it was only for a short space. After this war, the Carthaginians became involved with their own troops, who arose in mutiny because they could not get their pay, and Rome took advantage of this to rob them of the islands of Sardinia and Corsica, and at the same time to demand a large addition to the indemnity fund that had been agreed upon at the peace (B.C. 227). Such arbitrary treatment of a conquered foe could not fail to beget and keep alive the deepest feelings of resentment, of which, in after years, Rome reaped the bitter fruits.
