Mihr-Mihroe's campaign of 554
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.
The Byzantines had reinforced the region with a large force under the generals Martin, Bessas, and Bouzes, accompanied by Justin, son of Germanus. Martin stationed at a frontier stronghold guarding a strategic narrow pass at Telephis, while Bessas and Justin stationed nearby at Ollaria. The Sasanian general Mihr-Mihroe had stationed nearby at Kutais. Knowing that he could not defeat the Byzantine force right away, he reportedly spread disinformation by rumoring about himself being critically ill, which caused the Byzantine forces to relax their defenses (he actually died of illness afterward; see below). 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". 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.
