The Roman History · Amm. 16.2.6

And there, having, according to his custom, devoted a short time to rest, for the purpose of refreshing his men, he proceeded onwards towards Troyes; and strengthened his flanks that he might with the greater effect watch the barbarians, who attacked him in numerous bodies, which he avoided as well as he could, thinking them more numerous than they really were. Presently, however, having occupied some favourable ground, he descended upon one body of them, and routed it, and took some prisoners whom their own fears delivered to him; and then he allowed the rest, who now devoted all their energies to flying with what speed they could, to escape unattacked, as his men could not pursue them by reason of the weight of their armour.
