The civil administration was sometimes interrupted by the military defence of the empire. Crispus, a youth of the most amiable character, who had received with the title of Cæsar the command of the Rhine, distinguished himself by his conduct in several victories over the Franks and Alamanni, and taught the barbarians of that frontier to dread the eldest son of Constantine and the grandson of Constantius. The emperor himself had assumed the more difficult and important province of the Danube. The Goths, who in the time of Claudius and Aurelian had felt the weight of the Roman arms, respected the power of the empire, even in the midst of its intestine divisions. But the strength of that warlike nation was now restored by a peace of near fifty years; a new generation had arisen, who no longer remembered the misfortunes of ancient days: the Sarmatians of the lake Mæotis followed the Gothic standard, either as subjects or as allies, and their united force was poured upon the countries of Illyricum. Campona, Margus, and Bononia[58] appear to have been the scenes of several memorable sieges and battles; and though Constantine encountered a very obstinate resistance, he prevailed at length in the contest, and the Goths were compelled to purchase an ignominious retreat, by restoring the booty and prisoners they had taken. Nor was this advantage sufficient to satisfy the indignation of the emperor. He resolved to chastise, as well as to repulse, the insolent barbarians who had dared to invade the territories of Rome.
At the head of his legions he passed over the Danube, after repairing the bridge which had been constructed by Trajan, penetrated into the strongest recesses of Dacia, and when he had inflicted a severe revenge, condescended to give peace to the suppliant Goths on condition that, as often as they were required, they should supply his armies with a body of forty thousand soldiers. Exploits like these were no doubt honourable to Constantine, and beneficial to the state; but it may surely be questioned, whether they can justify the exaggerated assertion of Eusebius that all Scythia, as far as the extremity of the north, divided as it was into so many names and nations of the most various and savage manners, had been added by his victorious arms to the Roman Empire.
CONSTANTINE AND LICINIUS AGAIN AT WAR
[323 A.D.]
In this exalted state of glory it was impossible that Constantine should any longer endure a partner in the empire. Confiding in the superiority of his genius and military power, he determined, without any previous injury, to exert them for the destruction of Licinius, whose advanced age and unpopular vices seemed to offer a very easy conquest. But the old emperor, awakened by the approaching danger, deceived the expectations of his friends, as well as of his enemies. Calling forth that spirit and those abilities by which he had deserved the friendship of Galerius and the imperial purple, he prepared himself for the contest, collected the forces of the East, and soon filled the plains of Hadrianopolis with his troops, and the straits of the Hellespont with his fleet. The army consisted of 150,000 foot and 15,000 horse; and as the cavalry was drawn, for the most part, from Phrygia and Cappadocia, we may conceive a more favourable opinion of the beauty of the horses than of the courage and dexterity of their riders. The fleet was composed of 350 galleys of three ranks of oars. A hundred and thirty of these were furnished by Egypt and the adjacent coast of Africa. A hundred and ten sailed from the ports of Phœnicia and the isle of Cyprus; and the maritime countries of Bithynia, Ionia, and Caria were likewise obliged to provide 110 galleys. The troops of Constantine were ordered to rendezvous at Thessalonica; they amounted to above 120,000 horse and foot. The emperor was satisfied with their martial appearance, and his army contained more soldiers, though fewer men, than that of his eastern competitor.
