12. And then, fearing similar attempts by Procopius, he blocked up the three narrowest entrances into the northern province; one through Dacia, along the course of the different rivers; another, and that the most frequented, through the Succi; and the third through Macedonia, which is known as the Acontisma. And in consequence of these precautions the usurper was deprived of all hope of becoming master of Illyricum, and lost one great resource for carrying on the war.
13. In the mean time Valens, overwhelmed with the strange nature of this intelligence, and being already on his return through Gallo-Græcia, after he had heard what had happened at Constantinople, advanced with great diffidence and alarm; and as his sudden fears deprived him of his usual prudence, he fell into such despondency that he thought of laying aside his imperial robes as too heavy a burden; and in truth he would have done so if those about him had not hindered him from adopting so dishonourable a resolution. So, being encouraged by the opinions of braver men, he ordered two legions, known as the Jovian and the Victorian, to advance in front to storm the rebel camp.
14. And when they approached, Procopius, who had returned from Nicæa, to which city he had lately gone with the legion of Divitenses and a promiscuous body of deserters, which he had collected in a few days, hastened to Mygdus on the Sangarius.
15. And when the legions, being now prepared for battle, assembled there, and while both sides were exchanging missiles as if wishing to provoke an attack, Procopius advanced by himself into the middle, and under the guidance of favourable fortune, he remarked in the opposite ranks a man named Vitalianus (it is uncertain whether he had known him before), and having given him his hand and embraced him, he said, while both armies were equally astonished.
16. "And is this the end of the ancient fidelity of the Roman armies, and of the oaths taken under the strictest obligations of religion! Have you decided, O gallant men, to use your swords in defence of strangers, and that a degenerate Pannonian should undermine and upset everything, and so enjoy a sovereign power which he never even ventured to picture to himself in his prayers, while we lament over your ill-fortune and our own. Follow rather the race of your own noble princes which is now in arms, not with the view of seizing what does not belong to it, but with the hope of recovering its ancestral possessions and hereditary dignities."
17. All were propitiated by this conciliatory speech, and those who had come with the intention of fighting now readily lowered their standards and eagles, and of their own accord came over to him; instead of uttering their fearful yells, they unanimously saluted Procopius emperor, and escorted him to his camp, calling Jupiter to witness, after their military fashion, that Procopius should prove invincible.
VIII.
§ 1. Another fortunate circumstance occurred to swell the prosperity of the rebels. A tribune named Rumitalca, who had joined the partisans of Procopius, having been intrusted with the guard of the palace, digested a plan, and after mingling with the soldiers, passed over by sea to the town formerly known as Drepanum, but now as Helenopolis, and thence marched upon Nicæa, and made himself master of it before any one dreamt of such a step.
2. Valens sent Vadomarius, who had formerly been duke and king of the Allemanni, with a body of troops experienced in that kind of work, to besiege Nicæa, and proceeded himself to Nicomedia; and passing on from that city, he pressed the siege of Chalcedon with all his might; but the citizens poured reproaches on him from the walls, calling him Sabaiarius, or beer-drinker. Now Sabai is a drink made of barley or other grain, and is used only by poor people in Illyricum.
3. At last, being worn out by the scarcity of supplies and the exceeding obstinacy of the garrison, he was preparing to raise the siege, when the garrison who were shut up in Nicæa suddenly opened the gates and issued forth, destroying a great portion of the works of the besiegers, and under the command of the faithful Rumitalca hastened on eagerly in the hope of cutting off Valens, who had not yet quitted the suburb of Chalcedon. And they would have succeeded in their attempt if he had not learnt the imminence of his danger from some rumour, and eluded the enemy who were pressing on his track, by departing with all speed by a road lying between the lake Sunon and the winding course of the river Gallus. And through this circumstance Bithynia also fell into the hands of Procopius.
