The Siege of Akragas took place in 406 BC in Sicily; the Carthaginian enterprise ultimately lasted a total of eight months. The Carthaginian army under Hannibal Mago besieged the Dorian Greek city of Akragas in retaliation against Greek raids on Punic colonies in Sicily. The city had managed to repel Carthaginian attacks until a relief army from Syracuse defeated part of the besieging Carthaginian army and lifted the siege of the city.
