The Roman History · Amm. 24.1.2

And as a leader of experience and skill, fearing lest his ignorance of the country might lead to his being surprised by secret ambuscades, he began his march in line of battle. He ordered fifteen hundred skirmishers to precede him a short distance, who were to march slowly looking out on each side and also in front, to prevent any sudden attack. The infantry in the centre were under his own command, they being the flower and chief strength of the whole army, while on the right were some legions under Nevitta, who was ordered to march along the banks of the Euphrates. The left wing with the cavalry he gave to Arinthæus and Hormisdas, with orders to lead them in close order through the level and easy country of the plain. The rear was brought up by Dagalaiphus and Victor, and the last of all was Secundinus, Duke of Osdruena.
