The History of the Decline and Fall of the Roman Empire - Edward Gibbon [327]
[Footnote 86: The curious reader, who consults the Valesian fragment, p. 713, will probably accuse me of giving a bold and licentious paraphrase; but if he considers it with attention, he will acknowledge that my interpretation is probable and consistent.]
[Footnote 87: The situation of Aemona, or, as it is now called, Laybach, in Carniola, (D'Anville, Geographie Ancienne, tom. i. p. 187,) may suggest a conjecture. As it lay to the north-east of the Julian Alps, that important territory became a natural object of dispute between the sovereigns of Italy and of Illyricum.]
The first battle was fought near Cibalis, a city of Pannonia, situated on the River Save, about fifty miles above Sirmium. ^88 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 valor, 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. Licinius passed through that city, and breaking down the bridge on the Save, hastened to collect a new army in Dacia and Thrace. In his flight he bestowed the precarious title of Caesar on Valens, his general of the Illyrian frontier. ^89
[Footnote 88: Cibalis or Cibalae (whose name is still preserved in the obscure ruins of Swilei) was situated about fifty miles from Sirmium, the capital of Illyricum, and about one hundred from Taurunum, or Belgrade, and the conflux of the Danube and the Save. The Roman garrisons and cities on those rivers are finely illustrated by M. d'Anville in a memoir inserted in l'Academie des Inscriptions, tom. xxviii.]
