In 531, Bouzes was unable to participate at the Battle of Callinicum (19 April, 531). He was reportedly stationed at Amida, an illness preventing him from campaigning. Zacharias Rhetor mentions that Bouzes tasked his nephew Domnentiolus with leading an army to Abhgarsat. This location is only mentioned by Zacharias. The Byzantine forces faced the Sassanid army and were defeated. Domnentiolus himself was captured by his enemies and transported to the interior of the Sassanid Empire. In 532, the Eternal Peace was concluded between the two powers. Domnentiolus was released "in an exchange of prisoners"
