The Decline and Fall of the Roman Empire · Chapter 19 (5/7)

The ancient city of Amid or Amida,2301 which sometimes assumes the provincial appellation of Diarbekir,2302 is advantageously situate in a fertile plain, watered by the natural and artificial channels of the Tigris, of which the least inconsiderable stream bends in a semicircular form round the eastern part of the city. The emperor Constantius had recently conferred on Amida the honor of his own name, and the additional fortifications of strong walls and lofty towers. It was provided with an arsenal of military engines, and the ordinary garrison had been reinforced to the amount of seven legions, when the place was invested by the arms of Sapor.2303 His first and most sanguine hopes depended on the success of a general assault. To the several nations which followed his standard their respective posts were assigned; the south to the Vertae, the north to the Albanians, the east to the Chionites, inflamed with grief and indignation; the west to the Segestans, the bravest of his warriors, who covered their front with a formidable line of Indian elephants.2304 The Persians, on every side, supported their efforts, and animated their courage; and the monarch himself, careless of his rank and safety, displayed, in the prosecution of the siege, the ardor of a youthful soldier. After an obstinate combat the Barbarians were repulsed; they incessantly returned to the charge; they were again driven back with a dreadful slaughter, and two rebel legions of Gauls, who had been banished into the East, signalized their undisciplined courage by a nocturnal sally into the heart of the Persian camp. In one of the fiercest of these repeated assaults, Amida was betrayed by the treachery of a deserter, who indicated to the Barbarians a secret and neglected staircase, scooped out of the rock that hangs over the stream of the Tigris. Seventy chosen archers of the royal guard ascended in silence to the third story of a lofty tower which commanded the precipice; they elevated on high the Persian banner, the signal of confidence to the assailants and of dismay to the besieged; and, if this devoted band could have maintained their post a few minutes longer, the reduction of the place might have been purchased by the sacrifice of their lives. After Sapor had tried, without success, the efficacy of force and of stratagem, he had recourse to the slower but more certain operations of a regular siege, in the conduct of which he was instructed by the skill of the Roman deserters. The trenches were opened at a convenient distance, and the troops destined for that service advanced under the portable cover of strong hurdles, to fill up the ditch and undermine the foundations of the walls. Wooden towers were at the same time constructed, and moved forwards on wheels, till the soldiers, who were provided with every species of missile weapons, could engage almost on level ground with the troops who defended the rampart. Every mode of resistance which art could suggest, or courage could execute, was employed in the defence of Amida, and the works of Sapor were more than once destroyed by the fire of the Romans. But the resources of a besieged city may be exhausted. The Persians repaired their losses, and pushed their approaches; a large breach was made by the battering-ram, and the strength of the garrison, wasted by the sword and by disease, yielded to the fury of the assault. The soldiers, the citizens, their wives, their children, all who had not time to escape through the opposite gate, were involved by the conquerors in a promiscuous massacre.

But the ruin of Amida was the safety of the Roman provinces. As soon as the first transports of victory had subsided, Sapor was at leisure to reflect that, to chastise a disobedient city, he had lost the flower of his troops, and the most favorable season for conquest.2305 Thirty thousand of his veterans had fallen under the walls of Amida, during the continuance of a siege, which lasted seventy-three days; and the disappointed monarch returned to his capital with affected triumph and secret mortification. It is more than probable that the inconstancy of his Barbarian allies was tempted to relinquish a war in which they had encountered such unexpected difficulties; and that the aged king of the Chionites, satiated with revenge, turned away with horror from a scene of action where he had been deprived of the hope of his family and nation. The strength as well as the spirit of the army with which Sapor took the field in the ensuing spring was no longer equal to the unbounded views of his ambition. AD 360 Instead of aspiring to the conquest of the East, he was obliged to content himself with the reduction of two fortified cities of Mesopotamia, Singara and Bezabde;2306 the one situate in the midst of a sandy desert, the other in a small peninsula, surrounded almost on every side by the deep and rapid stream of the Tigris. Five Roman legions, of the diminutive size to which they had been reduced in the age of Constantine, were made prisoners, and sent into remote captivity on the extreme confines of Persia. After dismantling the walls of Singara, the conqueror abandoned that solitary and sequestered place; but he carefully restored the fortifications of Bezabde, and fixed in that important post a garrison or colony of veterans amply supplied with every means of defence, and animated by high sentiments of honor and fidelity. Towards the close of the campaign, the arms of Sapor incurred some disgrace by an unsuccessful enterprise against Virtha, or Tecrit, a strong, or as it was universally esteemed till the age of Tamerlane, an impregnable fortress of the independent Arabs.2307

The defence of the East against the arms of Sapor required, and would have exercised, the abilities of the most consummate general; and it seemed fortunate for the state that it was the actual province of the brave Ursicinus, who alone deserved the confidence of the soldiers and people. In the hour of danger, Ursicinus2308 was removed from his station by the intrigues of the eunuchs; and the military command of the East was bestowed, by the same influence, on Sabinian, a wealthy and subtle veteran, who had attained the infirmities, without acquiring the experience, of age. By a second order, which issued from the same jealous and inconstant councils, Ursicinus was again despatched to the frontier of Mesopotamia, and condemned to sustain the labors of a war, the honors of which had been transferred to his unworthy rival. Sabinian fixed his indolent station under the walls of Edessa; and while he amused himself with the idle parade of military exercise, and moved to the sound of flutes in the Pyrrhic dance, the public defence was abandoned to the boldness and diligence of the former general of the East. But whenever Ursicinus recommended any vigorous plan of operations; when he proposed, at the head of a light and active army, to wheel round the foot of the mountains, to intercept the convoys of the enemy, to harass the wide extent of the Persian lines, and to relieve the distress of Amida; the timid and envious commander alleged that he was restrained by his positive orders from endangering the safety of the troops. Amida was at length taken; its bravest defenders, who had escaped the sword of the Barbarians, died in the Roman camp by the hand of the executioner; and Ursicinus himself, after supporting the disgrace of a partial inquiry, was punished for the misconduct of Sabinian by the loss of his military rank. But Constantius soon experienced the truth of the prediction which honest indignation had extorted from his injured lieutenant, that, as long as such maxims of government were suffered to prevail, the emperor himself would find it is no easy task to defend his Eastern dominions from the invasion of a foreign enemy. When he had subdued or pacified the Barbarians of the Danube, Constantius proceeded by slow marches into the East; and, after he had wept over the smoking ruins of Amida, he formed, with a powerful army, the siege of Becabde. The walls were shaken by the reiterated efforts of the most enormous of the battering-rams; the town was reduced to the last extremity; but it was still defended by the patient and intrepid valor of the garrison, till the approach of the rainy season obliged the emperor to raise the siege, and ingloviously to retreat into his winter quarters at Antioch.2309 The pride of Constantius and the ingenuity of his courtiers were at a loss to discover any materials for panegyric in the events of the Persian war; while the glory of his cousin Julian, to whose military command he had entrusted the provinces of Gaul, was proclaimed to the world in the simple and concise narrative of his exploits.

In the blind fury of civil discord, Constantius had abandoned to the Barbarians of Germany the countries of Gaul, which still acknowledged the authority of his rival. A numerous swarm of Franks and Alemanni were invited to cross the Rhine by presents and promises, by the hopes of spoil, and by a perpetual grant of all the territories which they should be able to subdue.2310 But the emperor, who for a temporary service had thus imprudently provoked the rapacious spirit of the Barbarians, soon discovered and lamented the difficulty of dismissing these formidable allies, after they had tasted the richness of the Roman soil. Regardless of the nice distinction of loyalty and rebellion, these undisciplined robbers treated as their natural enemies all the subjects of the empire, who possessed any property which they were desirous of acquiring. Forty-five flourishing cities, Tongres, Cologne, Treves, Worms, Spires, Strasburgh, etc., besides a far greater number of towns and villages, were pillaged, and for the most part reduced to ashes. The Barbarians of Germany, still faithful to the maxims of their ancestors, abhorred the confinement of walls, to which they applied the odious names of prisons and sepulchres; and, fixing their independent habitations on the banks of rivers, the Rhine, the Moselle, and the Meuse, they secured themselves against the danger of a surprise by a rude and hasty fortification of large trees, which were felled and thrown across the roads. The Alemanni were established in the modern countries of Alsace and Lorraine; the Franks occupied the island of the Batavians, together with an extensive district of Brabant, which was then known by the appellation of Toxandria,2311 and may deserve to be considered as the original seat of their Gallic monarchy.2312 From the sources to the mouth, of the Rhine, the conquests of the Germans extended above forty miles to the west of that river, over a country peopled by colonies of their own name and nation; and the scene of their devastations was three times more extensive than that of their conquests. At a still greater distance the open towns of Gaul were deserted, and the inhabitants of the fortified cities, who trusted to their strength and vigilance, were obliged to content themselves with such supplies of corn as they could raise on the vacant land within the enclosure of their walls. The diminished legions, destitute of pay and provisions, of arms and discipline, trembled at the approach, and even at the name, of the Barbarians.

Under these melancholy circumstances, an unexperienced youth was appointed to save and to govern the provinces of Gaul, or rather, as he expressed it himself, to exhibit the vain image of Imperial greatness. The retired scholastic education of Julian, in which he had been more conversant with books than with arms, with the dead than with the living, left him in profound ignorance of the practical arts of war and government; and, when he awkwardly repeated some military exercise which it was necessary for him to learn, he exclaimed with a sigh, “O Plato, Plato, what a task for a philosopher!” Yet even this speculative philosophy, which men of business are too apt to despise, had filled the mind of Julian with the noblest precepts and the most shining examples; had animated him with the love of virtue, the desire of fame, and the contempt of death. The habits of temperance recommended in the schools are still more essential in the severe discipline of a camp. The simple wants of nature regulated the measure of his food and sleep. Rejecting with disdain the delicacies provided for his table, he satisfied his appetite with the coarse and common fare which was allotted to the meanest soldiers. During the rigor of a Gallic winter, he never suffered a fire in his bedchamber; and after a short and interrupted slumber he frequently rose in the middle of the night from a carpet spread on the floor, to despatch any urgent business, to visit his rounds, or to steal a few moments for the prosecution of his favorite studies.2313 The precepts of eloquence which he had hitherto practised on fancied topics of declamation were more usefully applied to excite or to assuage the passions of an armed multitude: and, although Julian, from his early habits of conversation and literature, was more familiarly acquainted with the beauties of the Greek language, he had attained a competent knowledge of the Latin tongue.2314 Since Julian was not originally designed for the character of a legislator or a judge, it is probable that the civil jurisprudence of the Romans had not engaged any considerable share of his attention: but he derived from his philosophic studies an inflexible regard for justice, tempered by a disposition to clemency; the knowledge of the general principles of equity and evidence, and the faculty of patiently investigating the most intricate and tedious questions which could be proposed for his discussion. The measures of policy and the operations of war must submit to the various accidents of circumstance and character, and the unpractised student will often be perplexed in the application of the most perfect theory. But in the acquisition of this important science, Julian was assisted by the active vigor of his own genius, as well as by the wisdom and experience of Sallust, and officer of rank, who soon conceived a sincere attachment for a prince so worthy of his friendship; and whose incorruptible integrity was adorned by the talent of insinuating the harshest truths without wounding the delicacy of a royal ear.2315
