Whilst Severus was engaged in his eastern war, he had reason to apprehend that the governor of Britain might pass the sea and the Alps, occupy the vacant seat of empire, and oppose his return with the authority of the senate and the forces of the West. The ambiguous conduct of Albinus, in not assuming the Imperial title, left room for negotiation. Forgetting, at once, his professions of patriotism, and the jealousy of sovereign power, he accepted the precarious rank of Cæsar, as a reward for his fatal neutrality. Till the first contest was decided, Severus treated the man, whom he had doomed to destruction, with every mark of esteem and regard. Even in the letter, in which he announced his victory over Niger, he styles Albinus the brother of his soul and empire, sends him the affectionate salutations of his wife Julia, and his young family, and entreats him to preserve the armies and the republic faithful to their common interest. The messengers charged with this letter were instructed to accost the Cæsar with respect, to desire a private audience, and to plunge their daggers into his heart. The conspiracy was discovered, and the too credulous Albinus, at length, passed over to the continent, and prepared for an unequal contest with his rival, who rushed upon him at the head of a veteran and victorious army. The military labors of Severus seem inadequate to the importance of his conquests. Two engagements, * the one near the Hellespont, the other in the narrow defiles of Cilicia, decided the fate of his Syrian competitor; and the troops of Europe asserted their usual ascendant over the effeminate natives of Asia. The battle of Lyons, where one hundred and fifty thousand Romans were engaged, was equally fatal to Albinus. The valor of the British army maintained, indeed, a sharp and doubtful contest, with the hardy discipline of the Illyrian legions. The fame and person of Severus appeared, during a few moments, irrecoverably lost, till that warlike prince rallied his fainting troops, and led them on to a decisive victory. The war was finished by that memorable day.
