 Severianus led a legion (perhaps the IX Hispana) into Armenia, but was trapped by the great Parthian general, Chosrhoes, at Elegia, a town just beyond the Cappadocian frontiers, high up past the headwaters of the Euphrates.Severianus made some attempt to fight Chosrhoes, but soon realized the futility of his campaign, and committed suicide.His legion was massacred.
