The experience of past faults, which may sometimes correct the mature age of an individual, is seldom profitable to the successive generations of mankind. The nations of antiquity, careless of each other’s safety, were separately vanquished and enslaved by the Romans. This awful lesson might have instructed the barbarians of the West to oppose, with timely counsels and confederate arms, the unbounded ambition of Justinian. Yet the same error was repeated, the same consequences were felt; and the Goths both of Italy and Spain, insensible of their approaching danger, beheld with indifference, and even with joy, the rapid downfall of the Vandals. After the failure of the royal line, Theudes, a valiant and powerful chief, ascended, in 531, the throne of Spain, which he had formerly administered in the name of Theodoric and his infant grandson. Under his command the Visigoths besieged the fortress of Ceuta on the African coast; but while they spent the sabbath day in peace and devotion, the pious security of their camp was invaded by a sally from the town; and the king himself, with some difficulty and danger, escaped from the hands of a sacrilegious enemy. It was not long before his pride and resentment were gratified by a suppliant embassy from the unfortunate Gelimer, who implored in his distress the aid of the Spanish monarch. But, instead of sacrificing these unworthy passions to the dictates of generosity and prudence, Theudes amused the ambassadors, till he was secretly informed of the loss of Carthage, and then dismissed them with obscure and contemptuous advice, to seek in their native country a true knowledge of the state of the Vandals. [Sidenote: [535-625 A.D.]] The long continuance of the Italian War delayed the punishment of the Visigoths; and the eyes of Theudes were closed before they tasted the fruits of his mistaken policy. After his death, the sceptre of Spain was disputed by a civil war. The weaker candidate solicited the protection of Justinian; and ambitiously subscribed a treaty of alliance, which deeply wounded the independence and happiness of his country. Several cities, both on the ocean and the Mediterranean, were ceded to the Roman troops, who afterwards refused to evacuate those pledges, as it should seem, either of safety or payment; and as they were fortified by perpetual supplies from Africa, they maintained their impregnable stations, for the mischievous purpose of inflaming the civil and religious factions of the barbarians. Seventy years elapsed before this painful thorn could be extirpated from the bosom of the monarchy; and as long as the emperors retained any share of these remote and useless possessions, their vanity might number Spain in the list of their provinces, and the successors of Alaric in the rank of their vassals.[b] MILITARY TACTICS UNDER JUSTINIAN [Sidenote: [527-565 A.D.]]
