Without a significant fleet and having lost their strategically important fortresses in Sicily, Corsica, and Sardinia, the Carthaginians had to look elsewhere for a source of money to fund their armies.
Some of the main reasons for the second war Carthage's intrigues with the Celts, Hannibal's rivalry with Rome in Spain and the great Carthaginian's general thirst for revenge on Rome.
Oh and in 256 Catherage was prepared to surrender to the Roman empire but they could not agree with there ridiculous demands so they ended up attacking the Romans
The war was fought to establish control over the strategic islands of Corsica and Sicily
Do you know what strategies the 2 empires used during the second Punic war?
Yeah I know once Hanniable took control of the Carthaginians he had over 90,000 infantry, 12,000 cavalries, and even elephants
The Romans used naval attacks they took the warfare to sea
Soon the Roman army was defeted by the Carthgins and in 216
The Romans to regain their stand in the battle while the Carthaginians lost their hold o Italy while Rome had many victories in Spain
In the end, Rome forced Carthage to give up their fleet and surrender
