The cavalry was placed under the command of Arinthseus and Prince Hormisdas, and was stationed at the extreme left, with orders to advance on a line parallel with the general course of the river.

Some picked legions under the command of Nevitta formed the right wing, and, resting on the Euphrates, maintained communication with the fleet.

Julian, with the main part of his troops, occupied the space intermediate between these two extremes, marching in a loose column which from front to rear covered a distance of above nine miles.

A flying corps of fifteen hundred men acted as an avant-guard under Count Lucilianus, and explored the country in advance, feeling on all sides for the enemy.
