Hieronymus Syracusanorum rex, cuius pater Hiero amicus populi Romani fuerat, ad Carthaginienses defecit et propter crudelitatem superbiamque a suis interfectus est. Tib. Sempronius Gracchus proconsul prospere adversus Poenos et Hannonem ducem ad Beneventum pugnavit servorum maxime opera, quos liberos esse iussit. Claudius Marcellus consul in Sicilia, quae prope tota ad Poenos defecerat, Syracusas obsedit. Philippo Macedonum regi bellum indictum est, qui ad Apolloniam nocturno proelio oppressus fugatusque in Macedoniam cum prope inermi exercitu profugit. Ad id bellum gerendum M. Valerius praetor missus. Res praeterea in Hispania a P. et Cn. Scipionibus adversus Carthaginienses gestas continet; a quibus Syphax rex Numidiae in amicitiam adscitus, qui a Masinissa Massyliorum rege pro Carthaginiensibus pugnante victus in Hispaniam ad Scipionem cum magna manu transiit contra Gades, ubi angusto freto Africa et Hispania dirimuntur. Celtiberi quoque in amicitiam recepti sunt, quorum auxiliis adscitis tunc primum mercennarium militem Romana castra habuerunt.
Hieronymus, king of the Syracusans, whose father Hiero had been a friend of the Roman people, revolted to the Carthaginians and because of his cruelty and arrogance was killed by his own men. Tiberius Sempronius Gracchus the proconsul fought with success against the Carthaginians and their general Hanno near Beneventum, mostly through the help of slaves, whom he ordered to be free men. Claudius Marcellus, the consul, in Sicily, which had almost entirely revolted to the Carthaginians, besieged Syracuse. War was declared on Philip, king of the Macedonians, who, surprised at Apollonia in a battle at night and put to flight, fled into Macedonia with an army almost disarmed. The praetor Marcus Valerius was sent to conduct that war. The book also contains operations against the Carthaginians in Spain by Publius and Gnaeus Scipio; by them Syphax, king of Numidia, was brought into friendship. Syphax, defeated by Masinissa, king of the Massylians, who was fighting for the Carthaginians, crossed over with a large force to Scipio in Spain, from a point opposite Gades, where Africa and Spain are separated by a narrow strait. The Celtiberians were also accepted into friendship, and after they were admitted as auxiliaries Roman camps then had mercenary soldiers for the first time.
