The Historians' History of the World 06 [The Early Roman Empire]

The successful valour of Julian had triumphed over all the obstacles that opposed his march to the gates of Ctesiphon. But the reduction, or even the siege, of the capital of Persia, was still at a distance; nor can the military conduct of the emperor be clearly apprehended, without a knowledge of the country which was the theatre of his bold and skilful operations. Twenty miles to the south of Baghdad, and on the eastern bank of the Tigris, the curiosity of travellers has observed some ruins of the palaces of Ctesiphon, which, in the time of Julian, was a great and populous city. The name and glory of the adjacent Seleucia were forever extinguished; and the only remaining quarter of that Greek colony had resumed, with the Assyrian language and manners, the primitive appellation of Coche.

Coche was situated on the western side of the Tigris; but it was naturally considered as a suburb of Ctesiphon, being supposedly connected with it by a permanent bridge of boats. The united parts contributed to form the common epithet of Al Modain, “the cities,” which the Orientals have bestowed on the winter residence of the Sassanids; and the whole circumference of the Persian capital was strongly fortified by the waters of the river, by lofty walls, and by impracticable morasses. Near the ruins of Seleucia the camp of Julian was fixed, and secured by a ditch and rampart against the sallies of the numerous and enterprising garrison of Coche. In this fruitful and pleasant country the Romans were plentifully supplied with water and forage; and several forts which might have embarrassed the motions of the army submitted, after some resistance, to the efforts of their valour. The fleet passed from the Euphrates into an artificial derivation of that river, which pours a copious and navigable stream into the Tigris, at a small distance below the great city. If they had followed this royal canal, which bore the name of Nahar-Malcha, the intermediate situation of Coche would have separated the fleet and army of Julian; and the rash attempt of steering against the current of the Tigris, and forcing their way through the midst of a hostile capital, must have been attended with the total destruction of the Roman navy. The prudence of the emperor foresaw the danger, and provided the remedy. As he had minutely studied the operations of Trajan in the same country, he soon recollected that his warlike predecessor had dug a new and navigable canal, which, leaving Coche on the right hand, conveyed the waters of the Nahar-Malcha into the river Tigris, at some distance above the cities. From the information of the peasants Julian ascertained the vestiges of this ancient work, which were almost obliterated by design or accident. By the indefatigable labour of the soldiers, a broad and deep channel was speedily prepared for the reception of the Euphrates. A strong dike was constructed to interrupt the ordinary current of the Nahar-Malcha: a flood of waters rushed impetuously into their new bed; and the Roman fleet, steering their triumphant course into the Tigris, derided the vain and ineffectual barriers which the Persians of Ctesiphon had erected to oppose their passage.

A BATTLE BY THE TIGRIS

As it became necessary to transport the Roman army over the Tigris, another labour presented itself, of less toil, but of more danger, than the preceding expedition. The stream was broad and rapid; the ascent steep and difficult; and the entrenchments, which had been formed on the ridge of the opposite bank, were lined with a numerous army of heavy cuirassiers, dexterous archers, and huge elephants, which (according to the extravagant hyperbole of Libanius) could trample, with the same ease, a field of corn or a legion of Romans. In the presence of such an enemy, the construction of a bridge was impracticable; and the intrepid prince, who instantly seized the only possible expedient, concealed his design till the moment of execution from the knowledge of the barbarians, of his own troops, and even of his generals themselves. Under the specious pretence of examining the state of the magazines, fourscore vessels were gradually unladen; and a select detachment, apparently destined for some secret expedition, was ordered to stand to their arms on the first signal. Julian disguised the silent anxiety of his own mind with smiles of confidence and joy; and amused the hostile nations with the spectacle of military games, which he insultingly celebrated under the walls of Coche. The day was consecrated to pleasure; but, as soon as the hour of supper was past, the emperor summoned his generals to his tent, and acquainted them that he had fixed that night for the passage of the Tigris. They stood in silent and respectful astonishment; but, when the venerable Sallust assumed the privilege of his age and experience, the rest of the chiefs supported with freedom the weight of his prudent remonstrances.
