The factious character of the troops composing the victorious army was disclosed as soon as Palermo had fallen into their hands. A division of Spanish Moors which had been prominent in the attack upon the city claimed the conquest for the Ommeyades. But the superior numbers of the Africans, as well as the fact that the expedition had been equipped at the expense of the Sultan of Kairoan, soon disposed of this demand, and Ziadet-Allah appointed his cousin, Abu-Fihr-Mohammed, as his representative in Sicily. The Moslems, now secure of a refuge in case of disaster and constantly receiving reinforcements, began to make rapid progress in the subjection of the island. Their foraging parties infested every accessible portion of the country, and carried their ravages to the gates of Taormina on the eastern coast. The general success attending their arms was, however, clouded by the assassination of Abu-Fihr, whose murderers found an asylum with the enemy. His successor, Fadl-Ibn-Yakub, defeated the Greeks in a pitched battle; but the victory was rendered unprofitable by the incessant contentions of the hostile parties which infested every portion of the military and naval service of the Saracens. The unfavorable condition of affairs having been reported to Ziadet-Allah, he sent Abu-al-Aghlab, the brother of Abu-Fihr, to assume the supreme command. Under the direction of this wise prince, whose talents speedily reconciled the disputes and suppressed the insolence of the soldiery, the conquest was prosecuted with renewed energy. He equipped a squadron of vessels provided with projectiles of Greek fire, the most formidable weapon of the age, and by its means soon became the master of the coast. The neighboring islands which had hitherto escaped the calamities with which Sicily had been visited were laid waste. Corleone, Platani, Marineo, and many smaller towns were taken. The garrisons of the cities still held by the Christians were so intimidated that they feared to venture beyond their walls. At the end of the year 840 one-third of the island was in the possession of the Arabs; their occupancy had lost its original character of a desultory inroad, and now began to assume the appearance of a permanent settlement; a truce, welcomed if not actually solicited by the fears of the Greeks, imparted an assurance of at least temporary security to the inhabitants, while an increasing trade with Egypt, Africa, and Spain assured the commercial fortunes of the new colony, whose power and prestige had already advanced to such a height that its alliance was eagerly sought by its natural enemies on the other side of the Strait of Messina.
