The politic genius of Charlemagne comprehended more fully than would be imagined from his panegyrist’s brief and dry account all the gravity of the affair of Roncesvalles. Not only did he take immediate vengeance by hanging Duke Lupus of Aquitaine, whose treason had brought down this mishap, and by reducing his two sons, Adalric and Sancho, to a more feeble and precarious condition; but he resolved to treat Aquitaine as he had but lately treated Italy, that is to say, to make of it, according to the correct definition of M. Fauriel, “a special kingdom, an integral portion, indeed, of the Frankish empire, but with an especial destination, which was that of resisting the invasions of the Andalusian Arabs, and confining them as much as possible to the soil of the peninsula.” This was, in some sort, giving back to the country its primary task as an independent duchy; and it was the most natural and most certain way of making the Aquitanians useful subjects, by giving play to their national vanity, to their pretensions of forming a separate people, and to their hopes of once more becoming, sooner or later, an independent nation. Queen Hildegarde, during her husband’s sojourn at Casseneuil, in 778, had borne him a son whom he called Louis, and who was afterward Louis the Debonair. Charlemagne, summoned a second time to Rome, in 781, by the quarrels of Pope Adrian I with the imperial court of Constantinople, brought with him his two sons, Pepin, aged only four years, and Louis, only three years, and had them anointed by the Pope—the former King of Italy, and the latter King of Aquitaine. On returning from Rome to Austrasia, Charlemagne sent Louis at once to take possession of his kingdom. From the banks of the Meuse to Orleans the little prince was carried in his cradle; but once on the Loire, this manner of travelling beseemed him no longer; his conductors would that his entry into his dominions should have a manly and warrior-like appearance; they clad him in arms proportioned to his height and age; they put him and held him on horseback; and it was in such guise that he entered Aquitaine. He came thither accompanied by the officers who were to form his council of guardians, men chosen by Charlemagne, with care, among the Frankish Leudes, distinguished not only for bravery and firmness, but also for adroitness, and such as they should be to be neither deceived nor scared by the cunning, fickle, and turbulent populations with whom they would have to deal. From this period to the
