Mago fought with Hannibal in the early Italian campaigns, and played a key role in major battles. Soon afterwards, along with Hamilcar, another brother, Mago moved on to command the Carthaginian forces in Spain. Defeat was suffered at Ilipa in 206 BC, however, and he soon retreated to Cádiz.
He then led a campaign to invade Italy (this time by sea) in 205 BC with 15,000 men. They sailed from Minorca to Ligures. He managed to capture Genoa, and held control of Northern Italy for three years.
Wounded in a battle in Cisalpine Gaul, he was recalled back to Carthage along with Hannibal to aid in its defence. Before arriving, however, he died at sea.
MagoBarca (also spelled Magon) (243 BC - 203 BC), was a member of the Barcid family, and played a major role in the Second Punic War leading forces of Carthage against the Roman Republic.
Mago has been largely eclipsed by his elder brothers, the famous Hannibal, and to a less extent his brother Hasdrubal as well, nevertheless he also was a great general.
The Barca brothers, aided by Hasdrubal Gisco battled the Romans under the command of the brothers Scipio throughout 215-212 BC.
Mago remained in Spain with Hasdrubal, the son of Gisco.
In 207 he was defeated by M. Junius Silanus, and in 206 the combined forces of Mago and Hasdrubal were scattered by Scipio Africanus in the decisive battle of Silpia.
Mago maintained himself for some time in Gades, but afterwards received orders to carry the war into Liguria.
