[4] [From Constantine Porphyrogenitus, The Embassies] When this war was ended, the Gallic mercenaries demanded of the Carthaginians the pay still due to them for their service in Sicily, together with the presents that Hamilcar had promised to give them. The African soldiers, although they were Carthaginian subjects, demanded the same things, on account of their service in Sicily, and this they did the more arrogantly as they saw that the Carthaginians were weakened and humbled; they were angry also on account of the killing of 3,000 of their own number whom the Carthaginians had crucified for deserting to the Romans.

When the Carthaginians refused the demands of both Gauls and Africans, they joined together and seized the city of Tunes, and also Utica, the largest city in Africa after Carthage. Starting thence they detached the rest of Africa, and brought over to their side some Numidians, and received into their ranks a vast number of fugitive slaves, and pillaged the Carthaginian possessions in every direction.

Being pressed by enemies on all sides the Carthaginians appealed to the Romans for aid against the Africans. The Romans did not send them a military force, but allowed them to draw supplies from Italy and Sicily, and to recruit mercenaries in Italy for this war only. They also sent deputies to Africa to arrange peace if they could, but they returned without accomplishing anything. The Carthaginians prosecuted the war vigorously.
