Who they were

Eustathius, born at Side about 270, was Bishop of Beroea and from about 323 of Antioch. At the Council of Nicaea he was one of the leading opponents of Arianism, and would not admit Arian priests to his diocese.

In 331 an Arian synod deposed him on false charges and Constantine banished him to Trajanopolis in Thrace. His people wished to defend him by arms, but he calmed them, urged them to keep the true faith, and went humbly into exile, where he died.

The miracles

There was never a formal cause: he has been honoured as a saint since before the Church's formal processes began.

Why that counted as sanctity

A bishop of Nicaea who suffered exile rather than yield to Arianism.
