Emperor Valens sent Vadomarius and Traianus against him, with a strong army and the order to keep the Sasanids under control but to avoid provoking them into battle.
The two generals decided to fight the bulk of the enemy army with their Armenian troops, which had proved valiant, and succeeded in pushing the Goths inside the valleys, where they hoped to defeat them by hunger.
[3] When the news of the bloody battle arrived in the East, Valens sent the West more troops under the magister equitum Saturninus, who was to substitute the two generals.
Traianus followed Valens, who wanted to defeat the Goths before the arrival from the West of his nephew Gratian with the Western army.
[6] Valens fought the Goths in the battle of Adrianople (August 9, 378); here, after the Roman line was shattered and had fled, Traianus cried that the Emperor had been left alone by his guards.
