George of Antioch's military career started soon after his migration to Sicily. He was initially a commander under Christodulus, with one of their first joint ventures being the 1123 attack on Mahdia, the seat of the Zirid emirs. The attack started out successfully with the seizure of the fortress of ad-Dimas near Mahdia, but the two admirals were soon defeated at the hands of the Zirids, and lost 200 of the 300 ships they had sailed from Sicily with. The next phases of George's military career took place in Africa and Greece. Starting in 1140, George began raiding the city of Mahdia on a regular basis, on King Roger II's orders. The attack on Mahdia was part of a larger invasion of Muslim Ifriqiya by the Normans. This is shown by the subsequent attacks on North African cities such as Sousse,
Sfax, and George's final attack on Mahdia in 1148, where he returned with 300 ships, taking the city for the last time. Roger II took that fight to Byzantium proper through raids on Greece starting in 1147. These attacks are recorded by Greek historian
Nicetas Choniates, who portrays George, his fellow Greek, as a pillager only motivated by greed. George's attacks began with the island of
Corfu, which he was able to bribe due to the excessive tax burden placed on the island by the Byzantines. George then sailed into the
Saronic Gulf between
Athens and the
Peloponnese peninsula, raiding towns such as
Monemvasia. George then sailed back around the Peloponnese and into the
Gulf of Corinth, where he and his troops set out onto the land, attacking
Thebes, sacking and looting the city, and absconding with great wealth. George then made his way to the city of
Corinth, which was lightly defended, and did much the same as he did in Thebes and returned to Sicily with his spoils in late 1147. George would return in 1148, but not before he was defeated by a coalition of
Venetian and Byzantine ships. In 1149, George then managed to sail through the Aegean and harass the defenses of Constantinople. == Legacy ==
