Zosimus, New History 1.50

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 Zosimus' New 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.

[1.50.1] During these occurrences in Italy and Pannonia, the emperor prepared to march against the Palmyrenians, who had subdued all Egypt, and the east, as far as Ancyra in Galatia, and would have acquired Bithynia even as far as Chalcedon if the inhabitants of that country had not learned that Aurelian was made emperor, and so shook off the Palmyrenian yoke.

[1.50.2] As soon as the emperor was on his march thither, Ancyra submitted to the Romans, and afterwards Tyana, and all the cities between that and Antioch. There finding Zenobia with a large army ready to engage, as he himself also was, he met and engaged her as honor obliged him. 

[1.50.3] But observing that the Palmyrene cavalry placed great confidence in their armor, which was very strong and secure, and that they were much better horsemen than his soldiers, he planted his infantry by themselves on the other side the Orontes. He charged his cavalry not to engage immediately with the vigorous cavalry of the Palmyrenians, but to wait for their attack, and then, pretending to fly, to continue so doing until they had wearied both the men and their horses through excess of heat and the weight of their armor, so that they could pursue them no longer.

[1.50.4] This project succeeded, and as soon as the cavalry of the emperor saw their enemy tired, and that their horses were scarcely able to stand under them, or themselves to move, they drew up the reins of their horses, and, wheeling round, charged them, and trod them under foot as they fell from their horses. By which means the slaugther was promiscuous, some falling by the sword, and others by their own and the enemies' horses.
