didn't really leave us any information about their side of things.
One small note. We don't know if Carthagenians left anything, as Romans were quick to destroy anything that wasn't pro-Roman.

We don't have any account of Alexander's campaign in full but for Arrian, a Roman governor of Anatolia in 2nd cent. CE
We don't have any account of Hannibal but for Polybius, a Pro Roman Greek.
We don't have any account of the destruction of the Temple and Jerusalem but for Josephus, a Hebrew who many have accused as Pro Roman, but without whom, we would have no knowledge whatsoever of that time.

What I am trying to say is that whenever we read history of that time, we must remember that we are looking it through a Roman perspective, as it is Roman history we are reading.

If we are to take it one step further, I think that Roman state put those who wrote against it in a form of

For example, we don't have any account of the Bar Kochba rebellion, nothing as accurate as the accounts of Josephus for the earlier Hebrew rebellion.
