Chapter XIV: Six Emperors At The Same Time, Reunion Of The Empire.—Part III.
When Hannibal marched from Gaul into Italy, he was obliged, first to discover, and then to open, a way over mountains, and through savage nations, that had never yielded a passage to a regular army. [53] The Alps were then guarded by nature, they are now fortified by art. Citadels, constructed with no less skill than labor and expense, command every avenue into the plain, and on that side render Italy almost inaccessible to the enemies of the king of Sardinia. [54] But in the course of the intermediate period, the generals, who have attempted the passage, have seldom experienced any difficulty or resistance. In the age of Constantine, the peasants of the mountains were civilized and obedient subjects; the country was plentifully stocked with provisions, and the stupendous highways, which the Romans had carried over the Alps, opened several communications between Gaul and Italy. [55] Constantine preferred the road of the Cottian Alps, or, as it is now called, of Mount Cenis, and led his troops with such active diligence, that he descended into the plain of Piedmont before the court of Maxentius had received any certain intelligence of his departure from the banks of the Rhine. The city of Susa, however, which is situated at the foot of Mount Cenis, was surrounded with walls, and provided with a garrison sufficiently numerous to check the progress of an invader; but the impatience of Constantine’s troops disdained the tedious forms of a siege. The same day that they appeared before Susa, they applied fire to the gates, and ladders to the walls; and mounting to the assault amidst a shower of stones and arrows, they entered the place sword in hand, and cut in pieces the greatest part of the garrison. The flames were extinguished by the care of Constantine, and the remains of Susa preserved from total destruction. About forty miles from thence, a more severe contest awaited him. A numerous army of Italians was assembled under the lieutenants of Maxentius, in the plains of Turin. Its principal strength consisted in a species of heavy cavalry, which the Romans, since the decline of their discipline, had borrowed from the nations of the East. The horses, as well as the men, were clothed in complete armor, the joints of which were artfully adapted to the motions of their bodies. The aspect of this cavalry was formidable, their weight almost irresistible; and as, on this occasion, their generals had drawn them up in a compact column or wedge, with a sharp point, and with spreading flanks, they flattered themselves that they could easily break and trample down the army of Constantine. They might, perhaps, have succeeded in their design, had not their experienced adversary embraced the same method of defence, which in similar circumstances had been practised by Aurelian. The skilful evolutions of Constantine divided and baffled this massy column of cavalry. The troops of Maxentius fled in confusion towards Turin; and as the gates of the city were shut against them, very few escaped the sword of the victorious pursuers. By this important service, Turin deserved to experience the clemency and even favor of the conqueror. He made his entry into the Imperial palace of Milan, and almost all the cities of Italy between the Alps and the Po not only acknowledged the power, but embraced with zeal the party, of Constantine.

[ The three principal passages of the Alps between Gaul and Italy, are those of Mount St. Bernard, Mount Cenis, and Mount Genevre. Tradition, and a resemblance of names, (Alpes Penninoe,) had assigned the first of these for the march of Hannibal, (see Simler de Alpibus.) The Chevalier de Folard (Polyp. tom. iv.) and M. d’Anville have led him over Mount Genevre. But notwithstanding the authority of an experienced officer and a learned geographer, the pretensions of Mount Cenis are supported in a specious, not to say a convincing, manner, by M. Grosley. Observations sur l’Italie, tom. i. p. 40, &c. ——The dissertation of Messrs. Cramer and Wickham has clearly shown that the Little St. Bernard must claim the honor of Hannibal’s passage. Mr. Long (London, 1831) has added some sensible corrections re Hannibal’s march to the Alps.—M]
