Zosimus, New History 2.22

Zosimus (Greek Ζώσιμος): Early Byzantine, pagan author of a history of the Roman Empire, published in the first quarter of the sixth century CE.

The translation of ZosimusNew History offered here was printed in 1814 by W. Green and T. Chaplin in London, and was probably prepared by J. Davis of the Military Chronicle and Military Classics Office. The translator is anonymous. The text was found at Tertullian.org. The notes were added by Jona Lendering.

[2.22.1] These he distributed into the different cities, and then came to Thessalonica, where having constructed a harbor (this city not possessing one before), he made new preparations for war against Licinius. For this purpose, he fitted out two hundred galleys of war; each with thirty oars, besides two thousand transport vessels, and raised a force of a hundred and twenty thousand foot, and ten thousand horsemen and sailors. Licinius, hearing of the great preparations of Constantine, sent messengers to every nation, commanding them to prepare a sufficient number of men for the navy, besides horse and foot soldiers.

[2.22.2] The Egyptians therefore sent out eighty galleys, the Phoenicians an equal number, the Ionians and Dorians of Asia sixty, the Cyprians thirty, the Carians twenty, the Bithynians thirty, and the Africans fifty. His foot-soldiers amounted to nearly a hundred and fifty thousand, but his horse only to fifteen thousand, which were sent to him from Phrygia and Cappadocia. Constantine's navy lay at Piraeus, that of Licinius in the Hellespont

[2.22.3] When they had thus established their naval and military forces, Licinius encamped at Adrianople in Thrace, whilst Constantine sent for his navy from Piraeus, which was built and manned chiefly in Greece. Advancing with his infantry from Thessalonica, he encamped on the bank of the river Hebrus, which runs to the left of Adrianople.

[2.22.4] At the same time, Licinius drew up his army in order of battle, extending from a mountain which is above the town two hundred stadia, as far as the junction of another river with the Hebrus; thus the armies continued opposite to each other for several days. Constantine. observing where the river was least broad, concerted this plan. 

[2.22.5] He ordered his men to bring trees from the mountain, and to tie ropes around them, as if he intended to throw a bridge over the river for the passage of his army. By this stratagem he deluded the enemy, and, ascending a hill on which were thick woods sufficient to conceal any that were in them, he planted there five thousand archers and eight hundred horse. 

[2.22.6] Having done this, he crossed the Hebrus at the narrowest place, and so surprised the enemy that many fled with all their speed, while others, who were amazed at his unexpected approach, were struck with wonder at his coming over so suddenly. 

[2.22.7] In the meantime, the rest of his army crossed the river in security, and a great slaughter commenced. Nearly thirty thousand fell; and about sunset Constantine took their camp, while Licinius, with all the forces he could muster, hastened through Thrace to his ships.
