Valens was the younger brother of Valentinian who made him co-emperor
soon after his own accession. He then sent Valens off to take care of the
eastern portion of the empire. Making Constantinopolis his capital, he dealt
with the Persian factor as best he could which wasn't all that great and saw his
borders shrink as a consequence. His ineptitude showed most compellingly at the
battle of Adrianopolis in 378. Resettled barbarians had been allowed within the
nominal borders of the empire but were allowed to keep their arms. As the
barbarians became squeezed from the double whammy of external tribes pushing
against their lands and the systematic and extra-official hard-line policies of
lower Roman government officials they became aggressive once more and aimed to
push southward.
Near the city of Adrianopolis they gathered with the intention of making war
and Valens prepared to meet them in battle. He sent for reinforcements from
Gratian but before these could arrive he figured in a bout of short-sighted
arrogance that he could go at it alone and claim the glory all to himself
afterward. On an exceedingly poorly executed attack plan the Romans attacked the
barbarians. In what apparently was meant to be a surprise attack, he rushed the
barbarians before getting his soldiers into formation and before they had eaten.
It was also a very hot and dusty day making their attack that much more
energy-sapping. The barbarians watched as their counterparts fumbled and figured
out their strategy. Their general sent his cavalry in an outflanking maneuver
and managed to encircle Valens's infantry and subsequently slaughtered most.
Valens himself perished in battle and the loss of the army along with the
demoralizing effect to the rest of the military was another step in the
inexorable fall of the empire almost one hundred years later.
