The siege of Phasis took place in 555–556 during the Lazic War between the Byzantine and Sasanian Empires. Expecting an easy victory, the Persians besieged the town of Phasis in Lazica, held by the Byzantines, but were defeated in the ensuing irregular battle. The main source for the siege is the 6th-century historian Agathias.^[2]
