But the stubborn perseverance of the Romans again neutralized the rapid success of Hannibal, at least at the most decisive point.

As soon as Hannibal turned his back on Capua to proceed to Apulia, the Roman armies once more gathered around that city, one at Puteoli and Volturnum under Appius Claudius, another at Casilinum under Quintus Fulvius, and a third on the Nolan road under the praetor Gaius Claudius Nero.

The three camps, well entrenched and connected with one another by fortified lines, precluded all access to the place, and the large, inadequately provisioned city could not but find itself compelled by the mere investment to surrender at no distant time, should no relief arrive.
As the winter of 542-3 drew to an end, the provisions were almost exhausted, and urgent messengers, who were barely able to steal through the well-guarded Roman lines, requested speedy help from Hannibal, who was at Tarentum, occupied with the siege of the citadel.

With 33 elephants and his best troops he departed by forced marches from Tarentum for Campania, captured the Roman post at Caiatia, and took up his camp on Mount Tifata close by Capua, in the confident expectation that the Roman generals would, now raise the siege as they had done the year before.

But the Romans, who had had time to entrench their camps and their lines like a fortress, did not stir, and looked on unmoved from their ramparts, while on one side the Campanian horsemen, on the other the Numidian squadrons, dashed against their lines.
