The Ecclesiastical History Of Theodoret by Theodoret
Chapter XXXII.--Of the expedition of Valens against the Goths and how he paid the penalty of his impiety.
Valens, however, spurned these excellent counsellors, and sent out his troops to join battle while he himself sat waiting in a hamlet for the victory. His troops could not stand against the barbarians' charge, turned tail and were slain one after another as they fled, the Romans fleeing at full speed and the barbarians chasing them with all their might. When Valens heard of the defeat he strove to conceal himself in the village where he lay, but when the barbarians came up they set the place on fire and together with it burnt the enemy of piety. Thus in this present life Valens paid the penalty of his errors.
