The Historians' History of the World 06 [The Early Roman Empire]

His cuirassiers are described as so many massy statues of steel, glittering with their scaly armour, and breaking with their ponderous lances the firm array of the Gallic legions. As soon as the legions gave way, the lighter and more active squadrons of the second line rode sword in hand into the intervals, and completed the disorder. In the meanwhile the huge bodies of the Germans were exposed, almost naked, to the dexterity of the oriental archers; and whole troops of those barbarians were urged by anguish and despair to precipitate themselves into the broad and rapid stream of the Drave. The number of the slain was computed at fifty-four thousand men and the slaughter of the conquerors was more considerable than that of the vanquished, a circumstance which proves the obstinacy of the contest, and justifies the observation of an ancient writer, that the forces of the empire were consumed in the fatal battle of Mursa by the loss of a veteran army sufficient to defend the frontiers or to add new triumphs to the glory of Rome. Notwithstanding the invectives of a servile orator, there is not the least reason to believe that the tyrant deserted his own standard in the beginning of the engagement. He seems to have displayed the virtues of a general and of a soldier till the day was irrecoverably lost and his camp in the possession of the enemy. Magnentius then consulted his safety, and, throwing away the imperial ornaments, escaped with some difficulty from the pursuit of the light horse, who incessantly followed his rapid flight from the banks of the Drave to the foot of the Julian Alps.

The detachments, however, which were ordered either to press or to intercept the flight of Magnentius, conducted themselves with the usual imprudence of success; and allowed him, in the plains of Ticinium, an opportunity of turning on his pursuers, and of gratifying his despair, by the carnage of a useless victory.

The pride of Magnentius was reduced by repeated misfortunes to sue, and to sue in vain, for peace. He first despatched a senator, in whose abilities he confided, and afterwards several bishops, whose holy character might obtain a more favourable audience, with the offer of resigning the purple, and the promise of devoting the remainder of his life to the service of the emperor. But Constantius, though he granted fair terms of pardon and reconciliation to all who abandoned the standard of rebellion, avowed his inflexible resolution to inflict a just punishment on the crimes of an assassin, whom he prepared to overwhelm on every side by the effort of his victorious arms. An imperial fleet acquired the easy possession of Africa and Spain, confirmed the wavering faith of the Moorish nations, and landed a considerable force, which passed the Pyrenees, and advanced towards Lyons, the last and fatal station of Magnentius. The temper of the tyrant, which was never inclined to clemency, was urged by distress to exercise every act of oppression which could extort an immediate supply from the cities of Gaul. Their patience was at length exhausted; and Trèves, the seat of prætorian government, gave the signal of revolt, by shutting her gates against Decentius, who had been raised by his brother to the rank either of cæsar or of augustus. From Trèves, Decentius was obliged to retire to Sens, where he was soon surrounded by an army of Germans, whom the pernicious arts of Constantius had introduced into the civil dissensions of Rome. In the meantime, the imperial troops forced the passages of the Cottian Alps, and in the bloody combat of Mount Seleucus, irrevocably fixed the title of rebels on the party of Magnentius.
