Gaius Laelius
Setting up camp across the isthmus with 27,500 men, Scipio isolated the town on the landward side, and with the Roman fleet (commanded by Gaius Laelius) blockading the town from the sea, the town was isolated from outside help. The Romans did not set up lines of circumvallation, intending to take the city by storm before help could arrive from the Carthaginian armies that were only 10 days away.
