The welcome news of the death of Julian, which a deserter revealed to the camp of Sapor, inspired the desponding monarch with a sudden confidence of victory. He immediately detached the royal cavalry, perhaps the ten thousand Immortals
, to second and support the pursuit; and discharged the whole weight of his united forces on the rear-guard of the Romans. The rear-guard was thrown into disorder; the renowned legions, which derived their titles from Diocletian and his warlike colleague, were broken and trampled down by the elephants; and three tribunes lost their lives in attempting to stop the flight of their soldiers. The battle was at length restored by the persevering valour of the Romans; the Persians were repulsed with a great slaughter of men and elephants; and the army, after marching and fighting a long summer’s day, arrived, in the evening, at Samara on the banks of the Tigris, about one hundred miles above Ctesiphon. On the ensuing day, the barbarians, instead of harassing the march, attacked the camp of Jovian, which had been seated in a deep and sequestered valley. From the hills, the archers of Persia insulted and annoyed the weary legionaries, and a body of cavalry, which had penetrated with desperate courage through the prætorian gate, was cut in pieces, after a doubtful conflict, near the imperial tent. In the succeeding night the camp at Carche was protected by the lofty dikes of the river; and the Roman army, though incessantly exposed to the vexatious pursuit of the Saracens, pitched their tents near the city of Dura, four days after the death of Julian. The Tigris was still on their left; their hopes and provisions were almost consumed; and the impatient soldiers who had fondly persuaded themselves that the frontiers of the empire were not far distant, requested their new sovereign, that they might be permitted to hazard the passage of the river. With the assistance of his wisest officers, Jovian endeavoured to check their rashness, by representing that if they possessed sufficient skill and vigour to stem the torrent of a deep and rapid stream, they would only deliver themselves naked and defenceless to the barbarians who had occupied the opposite banks.Yielding at length to their clamorous importunities, he consented that five hundred Gauls and Germans, accustomed from their infancy to the waters of the Rhine and Danube, should attempt the bold adventure, which might serve either as an encouragement, or as a warning, for the rest of the army. In the silence of the night they swam the Tigris, surprised an unguarded post of the enemy, and displayed at the dawn of day the signal of their resolution and fortune. The success of this trial disposed the emperor to listen to the promises of his architects, who proposed to construct a floating bridge of the inflated skins of sheep, oxen, and goats, covered with a floor of earth and fascines. Two important days were spent in the ineffectual labour; and the Romans, who already endured the miseries of famine, cast a look of despair on the Tigris, and upon the barbarians, whose numbers and obstinacy increased with the distress of the imperial army.
