The primary source of this conflict is the Byzantine historian Agathias, who seems to have had access to the reports of the inquiry into the defeat.
[1] The Byzantines had reinforced the region with a large force under the generals Martin, Bessas, and Bouzes, accompanied by Justin, son of Germanus.
The following Sasanian assault caused a general retreat of the Byzantines at Telephis, and later Ollaria, westward as far as the stronghold at Nesos "island"[2][3] (perhaps the Tekhuri–Abasha).
[4] Mihr-Mihroe was not able to follow up the victory due to supply problems and lack of siege equipment and retreated to Mocheresis, reinforcing his strategic garrison at Onoguris on his way, and died of illness shortly afterward.
[5][6] The Lazic king Gubazes soon protested to Justinian about the incompetence of the Byzantine generals, who dismissed some of them.
