The docs for this are minimal, just St. Jerome’s recollections about the sad state of the empire under Constantius II.
After these proceedings the Council (Ariminum, 359, adopting Sirmium) was dissolved. All returned in gladness to their own provinces. For the Emperor and all good men had one and the same aim, that the East and West should be knit together by the bond of fellowship. But wickedness does not long lie hidden, and the sore that is healed superficially before the bad humour has been worked off breaks out again. Valens and Ursacius and others associated with them in their wickedness, eminent Christian bishops of course, began to wave their palms, and to say they had not denied that He was a creature, but that He was like other creatures. At that moment the term ousia was abolished: the Nicene Faith stood condemned by acclamation. The whole world groaned, and was astonished to find itself Arian. Some, therefore, remained in their own communion, others began to send letters to those Confessors who as adherents of Athanasius were in exile; several despairingly bewailed the better relations into which they had entered. But a few, true to human nature, defended their mistake as an exhibition of wisdom. The ship of the Apostles was in peril, she was driven by the wind, her sides beaten with the waves: no hope was now left.
