Gaius Laelius
In the meantime, Lucius Marcius defeated Hanno, Mago's prefect, who had been sent from Gades (Cadiz) with a small force of Africans to hire local mercenaries and had armed 4,000 young men. Hanno escaped. Gaius Laelius' ships reached Carteia, in the Bay of Gibraltar. Some men offered to surrender Gades, but the plot was discovered and Mago arrested them and sent them to Carthage in a convoy of ships. When this passed the Strait of Gibraltar Laelius pursued it. There was a battle made chaotic by the current. Four Carthaginians ships were sunk and five fled to Africa. Back onshore, Laelius learnt that the plot had been discovered. He and Lucius Marcius agreed that they were wasting time and returned to Cartago Nova. Mago sent news of the mutiny of the Roman camp and the Illergete revolt to Carthage and urged for aid to be sent for the re-conquest of Hispania.
