The Historians' History of the World 06

Constantine had lately given his sister Anastasia in marriage to Bassianus, a man of a considerable family and fortune, and had elevated his new kinsman to the rank of cæsar. According to the system of government instituted by Diocletian, Italy and perhaps Africa were designed for his departments in the empire. But the performance of the promised favour was either attended with so much delay, or accompanied with so many unequal conditions, that the fidelity of Bassianus was alienated rather than secured by the honourable distinction which he had obtained. His nomination had been ratified by the consent of Licinius; and that artful prince, by the means of his emissaries, soon contrived to enter into a secret and dangerous correspondence with the new cæsar, to irritate his discontent, and to urge him to the rash enterprise of extorting by violence what he might in vain solicit from the justice of Constantine. But the vigilant emperor discovered the conspiracy before it was ripe for execution; and after solemnly renouncing the alliance of Bassianus, despoiled him of the purple, and inflicted the deserved punishment on his treason and ingratitude. The haughty refusal of Licinius, when he was required to deliver up the criminals who had taken refuge in his dominions, confirmed the suspicions already entertained of his perfidy; and the indignities offered at Æmona, on the frontiers of Italy, to the statues of Constantine, became the signal of discord between the two princes.

The first battle was fought near Cibalis, a city of Pannonia, situated on the river Savus, about fifty miles from Sirmium. From the inconsiderable forces which in this important contest two such powerful monarchs brought into the field, it may be inferred that the one was suddenly provoked, and that the other was unexpectedly surprised. The emperor of the West had only twenty thousand, and the sovereign of the East no more than five-and-thirty thousand men. The inferiority of number was, however, compensated by the advantage of the ground. Constantine had taken post in a defile about half a mile in breadth, between a steep hill and a deep morass, and in that situation he steadily expected and repulsed the first attack of the enemy. He pursued his success, and advanced into the plain. But the veteran legions of Illyricum rallied under the standard of a leader who had been trained to arms in the school of Probus and Diocletian. The missile weapons on both sides were soon exhausted; the two armies, with equal valour, rushed to a closer engagement of swords and spears, and the doubtful contest had already lasted from the dawn of the day to a late hour of the evening, when the right wing, which Constantine led in person, made a vigorous and decisive charge. The judicious retreat of Licinius saved the remainder of his troops from a total defeat; but when he computed his loss, which amounted to more than twenty thousand men, he thought it unsafe to pass the night in the presence of an active and victorious enemy. Abandoning his camp and magazines, he marched away with secrecy and diligence at the head of the greatest part of his cavalry, and was soon removed beyond the danger of a pursuit. His diligence preserved his wife, his son, and his treasures, which he had deposited at Sirmium.[56] Licinius passed through that city, and breaking down the bridge on the Savus, hastened to collect a new army in Dacia and Thrace. In his flight he bestowed the precarious title of Cæsar on Valens, his general of the Illyrian frontier.[57]
