Hamilcar refused, claiming the surrender was unnecessary, and the negotiation of the peace terms was left to Gisco, the commander of Lilybaeum, as the next most senior Carthaginian on the island.
This in turn agreed that Carthage would hand over what it still held of Sicily; relinquish several groups of islands nearby; release all Roman prisoners without ransom, although ransom would need to be paid to secure the release of prisoners held by the Romans; and pay an indemnity of 3,200 talents[note 1] of silver – 82,000 kilograms (81 long tons) – over 10 years.
Weakened by 30 years of war, Carthage agreed rather than enter into a conflict with Rome again; the additional payment and the renunciation of Sardinia and Corsica were added to the treaty.
[5][6][7] His works include a now lost manual on military tactics,[8] but he is known today for The Histories, written sometime after 146 BC, or about a century after the end of the war.
[10][11] Carthaginian written records were destroyed along with their capital, Carthage, in 146 BC and so Polybius's account of the First Punic War is based on several, now-lost, Greek and Latin sources.
[6][17] Modern historians usually also take into account the histories of Diodorus Siculus and Dio Cassius, and the 12th-century Byzantine chronicler Joannes Zonaras, who relied on much earlier sources, is also sometimes used.
[23] During this period Carthage, with its capital in what is now Tunisia, had come to dominate southern Hispania, much of the coastal regions of North Africa, the Balearic Islands, Corsica, Sardinia, and the western half of Sicily in a military and commercial empire.
[30] The Carthaginians were engaging in their traditional policy of waiting for their opponents to wear themselves out, in the expectation of then regaining some or all of their possessions and negotiating a mutually satisfactory peace treaty.
[31] The Carthaginian leadership preferred to expand their area of control in North Africa at the expense of the Numidians, and probably viewed Sicily as a secondary theatre.
[32] From 250 BC the Carthaginians held only two cities on Sicily: Lilybaeum and Drepana; these were well-fortified and situated on the west coast, where they could be supplied and reinforced without the Romans being able to use their superior army to interfere.
[40] Rome was also close to bankruptcy and the number of adult male citizens, who provided the manpower for the navy and the legions, had declined by 17 per cent since the start of the war.
[41] In late 243 BC realising they would not capture Drepana and Lilybaeum unless they could extend their blockade to the sea, the Roman Senate decided to build a new fleet.
[42] With the state's coffers exhausted, the Senate approached Rome's wealthiest citizens for loans to finance the construction of one ship each, repayable from the reparations to be imposed on Carthage once the war was won.
This caused him to be flexible during the negotiations as he was eager to conclude a definitive peace while he still had the authority to, and thus claim the credit for bringing the lengthy war to a close.
The news of a formed, experienced, anti-Carthaginian army in the heart of its territory spread rapidly and many cities and towns rose in rebellion; some were freshly conquered and all had been harshly oppressed to finance the recently ended war.
[61][62] Hiero II, the king of the Roman satellite kingdom of Syracuse, was allowed to supply Carthage with the large amounts of food it needed and was no longer able to obtain from its own hinterland.
The Roman Senate stated they considered the preparation of this force an act of war, and demanded Carthage cede Sardinia and Corsica, and pay an additional 1,200-talent indemnity, as peace terms.
[69][72] Polybius considered this "contrary to all justice"[69] and modern historians have variously described the Romans' behaviour as "unprovoked aggression and treaty-breaking",[69] "shamelessly opportunistic"[67] and an "unscrupulous act".
Sicily became the first Roman province as Sicilia, governed by a praetor – with the exception of Syracuse, which remained nominally independent and a close ally of Rome.
[71] When Carthage besieged the Roman-protected town of Saguntum[note 11] in eastern Iberia in 218 BC it ignited the Second Punic War with Rome.
