showed that the old barbarian spirit was but thinly covered by the veneer of Christianity and civilization which they had acquired in the last half-century. The struggle resolved itself into a repetition of the great raids of the third century: towns were sacked and the open country harried in the old style, nor was the war rendered less fierce by the fact that many runaway slaves and other outcasts among the provincial population joined the invaders. But the Roman armies still retained their old reputation; the ravages of the Goths were checked at the Balkans, and though joined by the remnants of the Ostrogoths from the Danube mouth, as well as by other tribes flying from the Huns, the Visigoths were at first held at bay by the imperial armies. A desperate pitched battle at Ad Salices, near the modern Kustendje thinned the ranks of both sides, but led to no decisive result.
Next year, however, the unwarlike Emperor, driven into the field by the clamours of his subjects, took the field in person, with great reinforcements brought from Asia Minor. At the same time his nephew Gratian, a gallant young prince who had succeeded to the Empire of the West, set forth through Pannonia to bring aid to the lands of the Lower Danube.
The personal intervention of Valens in the struggle was followed by a fearful disaster. In 378 a.d., the main body of the Goths succeeded in forcing the line of the Balkans; they were not far from Adrianople when the Emperor started to attack them, with a splendid army of 60,000 men. Every one expected to hear of a victory, for the reputation of invincibility still clung to the legions, and after six hundred years of war the disciplined infantry of Rome, robur peditum, whose day had lasted since the Punic wars, were still reckoned superior, when fairly handled, to any amount of wild barbarians.
But a new chapter of the history of the art of war was just commencing; during their sojourn in the plains of South Russia and Roumania the Goths had taken, first of all German races, to fighting on horseback. Dwelling in the Ukraine they had felt the influence of that land, ever the nurse of cavalry from the day of the Scythian to that of the Tartar and Cossack. They had come to “consider it more honourable to fight on horse than on foot,” and every chief was followed by his war-band of mounted men. Driven against their will into conflict with the empire, they found themselves face to face into the army that had so long held the world in fear, and had turned back their own ancestors in rout three generations before.
Valens found the main body of the Goths encamped in a great “laager,” on the plain north of Adrianople. After some abortive negotiations he developed an attack on their front, when suddenly a great body of horsemen charged in on the Roman flank. It was the main strength of the Gothic cavalry, which had been foraging at a distance; receiving news of the fight it had ridden straight for the battle field. Some Roman squadrons which covered the left flank of the Emperor's army were ridden down and trampled under foot. Then the Goths swept down on the infantry of the left wing, rolled it up, and drove it in upon the centre. So tremendous was their impact that legions and cohorts were pushed together in hopeless confusion. Every attempt to stand firm failed, and in a few minutes left, centre, and reserve, were one undistinguishable mass. Imperial guards, light troops, lancers, auxiliaries, and infantry of the line were wedged together in a press that grew closer every moment. The Roman cavalry saw that the day was lost, and rode off without another effort. Then the abandoned infantry realized the horror of their position: equally unable to deploy or to fly, they had to stand to be cut down. Men could not raise their arms to strike a blow, so closely were they packed; spears snapped right and left, their bearers being unable to lift them to a vertical position; many soldiers were stifled in the press. Into this quivering mass the Goths rode, plying lance and sword against the helpless enemy. It was not till forty thousand men had fallen that the thinning of the ranks enabled the survivors to break out and follow their cavalry in a headlong flight. They left behind them, dead on the field, the Emperor, the Grand Masters of the Infantry and Cavalry, the Count of the Palace, and thirty-five commanders of different corps.
The battle of Adrianople was the most fearful defeat suffered by a Roman army since Cannæ, a slaughter to which it is aptly compared by the contemporary historian Ammianus Marcellinus. The army of the East was almost annihilated, and was never reorganized again on the old Roman lines.
This awful catastrophe brought down on Constantinople the first attack which it experienced since it had changed its name from Byzantium. After a vain assault on Adrianople, the victorious Goths pressed rapidly on towards the imperial city. Harrying the whole country side as they passed by, they presented themselves before the “Golden Gate,” its south-western exit. But the attack was destined to come to nothing: “their courage failed them when they looked on the vast circuit of walls and the enormous extent of streets; all that mass of riches within appeared inaccessible to them. They cast away the siege machines which they had prepared, and rolled backward on to Thrace.”3 Beyond skirmishing under the walls with a body of Saracen cavalry which had been brought up to strengthen the garrison, they made no hostile attempt on the city. So forty years after his death, Constantine's prescience was for the first time justified. He was right in believing that an impregnable city on the Bosphorus would prove the salvation of the Balkan Peninsula even if all its open country were overrun by the invader.
The unlucky Valens was succeeded on the throne by Theodosius, a wise and virtuous prince, who set himself to repair, by caution and courage combined, the disaster that had shaken the Roman power in the Danube lands. With the remnants of the army of the East he made head against the barbarians; without venturing to attack their main body, he destroyed many marauders and scattered bands, and made the continuance of the war profitless to them. If they dispersed to plunder they were cut off; if they held together in masses they starved. Presently Fritigern died, and Theodosius made peace with his successor Athanarich, a king who had lately come over the Danube at the head of a new swarm of Goths from the Carpathian country. Theodosius frankly promised and faithfully observed the terms that Fritigern had asked of Valens ten years before. He granted the Goths land for their settlement in the Thracian province which they had wasted, and enlisted in his armies all the chiefs and their war-bands. Within ten years after the fight of Adrianople he had forty thousand Teutonic horsemen in his service; they formed the best and most formidable part of his host, and were granted a higher pay than the native Roman soldiery. The immediate military results of the policy of Theodosius were not unsatisfactory; it was his Gothic auxiliaries who won for him his two great victories over the legions of the West, when in a.d. 388 he conquered the rebel Magnus Maximus, and in a.d. 394 the rebel Eugenius.
But from the political side the experiment of Theodosius was fraught with the greatest danger that the Roman Empire had yet known. When barbarian auxiliaries had been enlisted before, they had been placed under Roman leaders and mixed with equal numbers of Roman troops. To leave them under their own chiefs, and deliberately favour them at the expense of the native soldiery, was a most unhappy experiment. It practically put the command of the empire in their hands; for there was no hold over them save their personal loyalty to Theodosius, and the spell which the grandeur of the Roman name and Roman culture still exercised over their minds. That spell was still strong, as is shown in the story which the Gothic historian Jornandes tells about the visit of the old King Athanarich to Constantinople. “When he entered the royal city, ‘Now,’ said he, ‘do I at last behold what I had often heard and deemed incredible.’ He passed his eyes hither and thither admiring first the site of the city, then the fleets of corn-ships, then the lofty walls, then the crowds of people of all nations, mingled as the waters from divers springs mix in a single pool, then the ranks of disciplined soldiery. And at last he cried aloud, ‘Doubtless the Emperor is as a god on earth, and he who raises a hand against him is guilty of his own blood.’ ” But this impression was not to continue for long. In a.d. 395, the good Emperor Theodosius, “the lover of peace and of the Goths,” as he was called, died, and left the throne to his two weakly sons Arcadius and Honorius.
