The Roman History · Amm. 18.9.3

In the garrison of this town, the fifth or Parthian legion was always located with a considerable squadron of native cavalry. But at that time six legions, by forced marches, had outstripped the Persian host in its advance, and greatly strengthened the garrison: they were the Magnentian and Decentian legions whom, after the end of the civil war, the emperor had sent as mutinous and discontented to the East, since there the only danger was from foreign wars: the tenth, and the thirteenth legion called the Fretensian: and two legions of light infantry called præventores and superventores, with Ælian, who was now a count. Of these latter, when only new recruits, we have already spoken, as sallying out from Singara at the instigation of this same Ælian, then only one of the guard, and slaying a great number of Persians whom they had surprised in their sleep.
