8. Leonas heard this, and, after receiving letters from Julian, stating what had occurred, was dismissed in safety: the only one of the emperor's appointments which was allowed to take effect was that of Nebridius, which Julian in his letters had plainly said would be in accordance with his wishes. For he himself had some time before appointed Anatolius to be master of the ceremonies, having been formerly his private secretary; and he had also made such other appointments as seemed useful and safe. 9. And since, while matters were going on in this matter, Lupicinus, as being a proud and arrogant man, was an object of fear, though absent and still in Britain; and since there was a suspicion that if he heard of these occurrences while on the other side of the channel, he might cause disorders in the island, a secretary was sent to Boulogne to take care that no one should be allowed to cross; and as that was contrived, Lupicinus returned without hearing of any of these matters, and so had no opportunity of giving trouble. X. § 1. But Julian, being gratified at his increase of rank, and at the confidence of the soldiers in him, not to let his good fortune cool, or to give any colour for charging him with inactivity or indolence, after he had sent his envoys to Constantius, marched to the frontier of the province of lower Germany; and having with him all the force which the business in hand demanded, he approached the town of Santon.[113] 2. Then crossing the Rhine, he suddenly entered the district belonging to a Frank tribe, called the Attuarii, men of a turbulent character, who at that very moment were licentiously plundering the districts of Gaul. He attacked them unexpectedly while they were apprehensive of no hostile measures, but were reposing in fancied security, relying on the ruggedness and difficulty of the roads which led into their country, and which no prince within their recollection had ever penetrated. He, however, easily surmounted all difficulties, and having put many to the sword and taken many prisoners, he granted the survivors peace at their request, thinking such a course best for their neighbours. 3. Then with equal celerity he repassed the river, and examining carefully the state of the garrisons on the frontier, and putting them in a proper state, he marched towards Basle; and having recovered the places which the barbarians had taken and still retained in their hands, and having carefully strengthened them, he went to Vienne, passing through Besançon, and there took up his winter quarters. XI. § 1. These were the events which took place in Gaul, and while they were thus conducted with prudence and good fortune, Constantius, having summoned Arsaces, king of Armenia, and having received him with great courtesy, advised and exhorted him to continue friendly and faithful to us.
