The implacable and perfidious spirit of the Berbers, whom no treaties could control, now broke out in the prosecution of petty hostilities, which the scattered forces of the Moslems were powerless to prevent. Forays were made upon isolated settlements, flocks were driven off, hamlets given to the flames, and even the security of the rising colony of Kairoan was threatened. Emboldened by their success, the Berber chief’s confederated for the total destruction of the Moslems. Koceila, an influential chieftain, who had been wantonly insulted and maimed by Okbah and was now kept a close prisoner in the camp, was the moving spirit of the conspiracy. Learning too late of the plan of the enemy, Okbah was compelled to weaken his army, and while a detachment for the relief of Kairoan was on the march, it was suddenly attacked near Tehuda by an overwhelming force of barbarian cavalry. The little band of Mussulmans, less than four hundred in number, seeing the hopelessness of the contest, commended themselves to God, and, casting away their scabbards, perished to a man, scimetar in hand. The tombs of these martyrs are still objects of veneration to the devout, and Zab, where they are situated, enjoys the sanctity, privileges, and lucrative trade of a place of pilgrimage. The Franks and Berbers with their usual inconstancy now flocked to the standard of Koceila, who assumed the title of an independent sovereign and for five years remained the undisputed ruler of Ifrikiyah. At the expiration of that period, a fresh army of Arabs under Zoheir defeated the Berbers in a decisive battle, and, Koceila having been killed, the lieutenant of the Khalif again asserted his unstable authority.

But none of the latter had mustered such a force, or could have controlled such vast resources, as did the new commander-in-chief. His office, as Governor of Egypt, placed at his disposal the enormous wealth of that fertile country, and he marched out of Alexandria at the head of a thoroughly equipped army of forty thousand veterans. He was well provided with scaling ladders and the various engines for the siege of fortified places, while the success of the Moslems in the East had inspired them with confidence, and afforded experience in the attack upon fortifications, a branch of warfare in which they had at first been entirely deficient. Resolving to reduce the strongholds of the coast, which were still in possession of the Greeks, Hassan, after traversing the region which had been desolated, and partially colonized by former commanders, advanced at once upon Carthage. This famous city, which had preserved, amidst unparalleled disaster, the prestige and the traditions of its former
