The Roman History · Amm. 29.5.47

And the next morning at daybreak the two armies, breathing terrible threats against each other, advanced to engage in battle: nearly twenty thousand barbarians constituted the front of their army, with very large reserves posted behind, out of sight, with the intention that they should steal forward gradually, and hem in our battalions with their vast and unexpected numbers. These were also supported by a great number of auxiliaries of the Jesalenian tribes, whom we have mentioned as having promised reinforcements and supplies to ourselves.
