Events

By place

Carthage

The Roman general, Publius Cornelius Scipio, while undertaking peace negotiations with the Carthaginians at Utica, makes a surprise attack on the Carthaginian camp and destroys it. Then, sweeping down on the forces that the Carthaginians and their allies, the Numidians, are trying to muster on the Great Plains near the upper Bagradas River (in modern Tunisia), he smashes that army in the Battle of the Great Plains. The Numidian king, Syphax, and the Carthaginian leader, Hasdrubal Gisco, manage to escape separately.
The Roman general, Gaius Laelius, and Rome's Numidian ally, Masinissa, follow Syphax towards Cirta, the Numidian capital. In the pursuit, Syphax is captured after his badly wounded horse throws him off. He is delivered to Scipio and is made a prisoner of the Romans, dying in the Italian town of Alba Fucens later in the year.
Masinissa becomes king of both the Massyli and the Massaesyli tribes in Numidia and remains a loyal ally to the Romans.
Hasdrubal Gisco persuades the Carthaginians to raise a new army and to send for Hannibal to return home from Italy. Hannibal finally leaves Italy and returns to Carthage.
The Carthaginian general, Mago Barca, is defeated and wounded by the Romans in a battle in Cisalpine Gaul. He dies of his wounds on the return voyage to Carthage.
A preliminary armistice between Carthage and Rome is declared and the Carthaginian armies accept Scipio's severe terms. However, on his return to Carthage, Hannibal concentrates the remnants of the Carthaginian forces at Hadrumetum (modern Sousse, Tunisia) and prepares them for battle.
