It absolutely pains me that our primary sources on Carthage are severely lacking on account of one Scipio Aemilianus. That being said, Hannibal's wild ride through Spain, Gaul, and Italy, while a delight to the Carthaginian generals and soldiers who had a score to settle with Rome, caused much grumbling among the landed Carthaginian aristocracy. The traditional narrative is that these landowners had a ringleader in the form of Hanno the Younger, who if you were a rabid Hannibal fanboy like me in my yout', treacherously stabbed Hannibal in the back when he was on the cusp of victory after Cannae, sabotaging efforts to send Hannibal reinforcements.
Now of course, the reasons for Hannibal's defeat go beyond Hanno and his cabal (it very well could be that Hanno's involvement in Hannibal's slow decline in Italy is heavily overstated). However, it is very clear that while powerful in Barcid-conquered Spain, Hannibal more than likely had many an enemy in the Carthaginian establishment. Had by whatever means Hannibal achieved victory in the Second Punic War (now more than likely equipped with a massive army of Spaniards, Gauls, Africans, and Italians), might we see a similar situation to Caesar and Pompey with Hannibal and Hanno?
