The siege of Enna or Castrogiovanni was launched by the Aghlabids against the important Byzantine city of Enna in 859. The Aghlabid forces managed to capture the city.
Following the fall of Palermo in 831, the key to Byzantine defense became the fortified city of Castrogiovanni (modern-day Enna), governed by Theodotus. The city is on a high mountain, dominating all neighboring heights. Aiming to capture the city, as it was the seat of the Byzantine government of Sicily. Castrogiovanni was accessible by two tortuous and narrow gorges.
A party of Arabs whom the governor, Abbas bin al-Fadhl, had sent to ravage the outskirts of Enna. They managed to capture a Greek prisoner. Abbas ordered him to be executed. The prisoner begged for mercy in exchange for helping them capture Enna, and Abbas agreed to this offer. The Byzantine garrison did not expect any attack and minimized their defenses.
Abbas, with a cavalry force of 2,000, headed towards Castrogiovanni. Taking advantage of the darkness, Abbas dispatched a contingent under his uncle, Rabah, to a secret passage the prisoner had told them about. An aqueduct leads to the center of Castrogiovanni. The Arabs entered the aqueduct, then proceeded to kill the defenders of the city and open the gates for Abbas.
The city fell on January 24. The Arabs captured immense wealth and many prisoners, and part of them were sent to the Abbasid caliph, al-Mutawakkil. Abbas ordered the construction of a mosque to celebrate this victory in the palace of the Patricians.
The capture of Castrogiovanni destroyed the Byzantine power in Sicily and forced them to relocate their seat to Syracuse. Due to this defeat, the Byzantine emperor, Michael III, dispatched a navy of 300 ships to rescue Castrogiovanni under the command of Constantine Kontomytes. The Byzantine Navy suffered a crushing defeat and lost 100 of their ships.
