In 254, 255, and 257, Valerian again became "Consul Ordinarius." By 257, he had recovered Antioch and returned the province of Syria to Roman control. The following year, the Goths ravaged Asia Minor. In 259, Valerian moved on to Edessa, but an outbreak of plague killed a critical number of legionaries, weakening the Roman position, and the town was besieged by the Persians. At the beginning of 260, Valerian was decisively defeated in the Battle of Edessa and held prisoner for the remainder of his life. Valerian's capture was a tremendous defeat for the Romans.
