The Battle of Anglon took place in 543 AD, during the Byzantine (East Roman) invasion of Sasanian-ruled Armenia ("Persarmenia") in the early phase of the Lazic War. After receiving the news of a rebellion in Persia and an epidemic in King Khosrow I's army, the Roman armies in the East under the orders of Emperor Justinian I initiated a hasty invasion of Persarmenia. The outnumbered Persian forces in the region performed a meticulous ambush at Anglon, decisively defeating the Roman forces in a siege-like confrontation.
