21. And from that city he sent Severus to succeed Marcellus, a man of great experience and ripe skill in war, and summoned Ursicinus to himself. He, having gladly received the letter of summons, came to Sirmium, with a large retinue, and after a long deliberation on the peace which Musonianus had reported as possible to be made with the Persians, he was sent back to the East with the authority of commander-in-chief, and the older officers of our company having been promoted to commands over the soldiers, we younger men were ordered to follow him to perform whatever he commanded us for the service of the republic.

A.D. 357.
§ 1. But Julian, having passed his winter at Sens, amid continual disturbance, in the ninth consulship of the emperor, and his own second, while the threats of the Germans were raging on all sides, being roused by favourable omens, marched with speed to Rheims, with the greater alacrity and joy because Severus was in command of the army there; a man inclined to agree with him, void of arrogance, but of proved propriety of conduct and experience in war, and likely to follow his lawful authority, obeying his general like a well-disciplined soldier.
2. In another quarter, Barbatio, who after the death of Silvanus had been promoted to the command of the infantry, came from Italy by the emperor's orders, to Augst, with 25,000 heavy-armed soldiers.
3. For the plan proposed and very anxiously prepared was, that the Allemanni, who were in a state of greater rage than ever, and were extending their incursions more widely, should be caught between our two armies, as if between the arms of a pair of pincers, and so driven into a corner and destroyed.
4. But while these well-devised plans were being pressed forward, the barbarians, in joy at some success which they had obtained, and skilful in seizing every opportunity for plunder, passed secretly between the camps of the armies, and attacked Lyons unexpectedly. And having plundered the district around, they would have stormed and burnt the city itself, if they had not found the gates so strongly defended that they were repulsed; so that they only destroyed all they could find outside the city.
5. When this disaster was known, Cæsar, with great alacrity, despatched three squadrons of light cavalry, of approved valour, to watch three lines of road, knowing that beyond all question the invaders must quit the district by one of them.
6. Nor was he mistaken; for all who came by these roads were slaughtered by our men, and the whole of the booty which they were carrying off was recovered unhurt. Those alone escaped in safety who passed by the camp of Barbatio, who were suffered to escape in that direction because Bainobaudes the tribune, and Valentinian (afterwards emperor), who had been appointed to watch that pass with the squadrons of cavalry under their orders, were forbidden by Cella (the tribune of the Scutarii, who had been sent as colleague to Barbatio) to occupy that road, though they were sure that by that the Germans would return to their own country.
