Edward Gibbon 
The Destruction of the Western Roman Empire [EPUB ebook] 

The loss or desolation of the provinces, from the Ocean to the Alps, impaired the glory and greatness of Rome: her internal prosperity was irretrievably destroyed by the separation of Africa. The rapacious Vandals confiscated the patrimonial estates of the senators, and intercepted the regular subsidies, which relieved the poverty and encouraged the idleness of the plebeians. The distress of the Romans was soon aggravated by an unexpected attack; and the province, so long cultivated for their use by industrious and obedient subjects, was armed against them by an ambitious Barbarian. The Vandals and Alani, who followed the successful standard of Genseric, had acquired a rich and fertile territory, which stretched along the coast above ninety days' journey from Tangier to Tripoli; but their narrow limits were pressed and confined, on either side, by the sandy desert and the Mediterranean. The discovery and conquest of the Black nations, that might dwell beneath the torrid zone, could not tempt the rational ambition of Genseric; but he cast his eyes towards the sea; he resolved to create a naval power, and his bold resolution was executed with steady and active perseverance. The woods of Mount Atlas afforded an inexhaustible nursery of timber: his new subjects were skilled in the arts of navigation and ship-building; he animated his daring Vandals to embrace a mode of warfare which would render every maritime country accessible to their arms; the Moors and Africans were allured by the hopes of plunder; and, after an interval of six centuries, the fleets that issued from the port of Carthage again claimed the empire of the Mediterranean. The success of the Vandals, the conquest of Sicily, the sack of Palermo, and the frequent descents on the coast of Lucania, awakened and alarmed the mother of Valentinian, and the sister of Theodosius. Alliances were formed; and armaments, expensive and ineffectual, were prepared, for the destruction of the common enemy; who reserved his courage to encounter those dangers which his policy could not prevent or elude. The designs of the Roman government were repeatedly baffled by his artful delays, ambiguous promises, and apparent concessions; and the interposition of his formidable confederate, the king of the Huns, recalled the emperors from the conquest of Africa to the care of their domestic safety. The revolutions of the palace, which left the Western empire without a defender, and without a lawful prince, dispelled the apprehensions, and stimulated the avarice, of Genseric. He immediately equipped a numerous fleet of Vandals and Moors, and cast anchor at the mouth of the Tyber, about three months after the death of Valentinian, and the elevation of Maximus to the Imperial throne…
