Gisco (died 239 BC)

Gisco was a Carthaginian general who served during the closing years of the First Punic War (264–239 BC) and took a leading part in the events which sparked the Mercenary War. He was a citizen of the city state of Carthage, which was located in what is now Tunisia. His date of birth and age at death are both unknown, as are his activities prior to his rise to prominence towards the end of the First Punic War.

When the Carthaginians conceded defeat in the war in 241 BC, Gisco was commander of the major base of Lilybaeum (modern Marsala) on Sicily, subordinate to Hamilcar Barca, the overall Carthaginian commander on the island. On being ordered to negotiate a peace treaty, Hamilcar retired to Carthage in a rage, leaving Gisco, as the next most senior commander, in charge of negotiations with the Romans. These resulted in the Treaty of Lutatius, which ended the war. By this time the troops whom he had sent from Sicily to Africa to be repatriated were in a mutinous state over a pay dispute, and Gisco, who had a good reputation with them, was hastily recalled to deal with the situation. The discontent seemed to have abated when, for some unknown reason, discipline broke down. Several soldiers insisted that no deal with Carthage was acceptable, a riot broke out and dissenters were stoned to death. Gisco and his staff were taken prisoner and his treasury was seized.

He was held prisoner for two years, during which the rebels suffered several defeats. After a large force of rebels deserted to the Carthaginians in 239 BC and were well received, the rebel leaders feared the disintegration of their army; they were aware that such generous terms would not be extended to them personally. To remove the possibility of any goodwill between the sides, they had Gisco and 700 other Carthaginian prisoners tortured to death.
