Meantime both sent messages to king Vologeses, advising him to choose peace rather than war, and to give hostages and so continue the habitual reverence of his ancestors towards the people of Rome. Vologeses, wishing to prepare for war at an advantage, or to rid himself of suspected rivals under the name of hostages, delivered up some of the noblest of the Arsacids. A centurion, Insteius, sent perhaps by Ummidius on some previous occasion, received them after an interview with the king. Corbulo, on knowing this, ordered Arrius Varus, commander of a cohort, to go and take the hostages. Hence arose a quarrel between the commander and the centurion, and to stop such a scene before foreigners, the decision of the matter was left to the hostages and to the envoys who conducted them. They preferred Corbulo, for his recent renown, and from a liking which even enemies felt for him. Then there was a feud between the two generals; Ummidius complained that he was robbed of what his prudence had achieved, while Corbulo on the other hand appealed to the fact that Vologeses had not brought himself to offer hostages till his own appointment to the conduct of the war turned the king's hopes into fears. Nero, to compose their differences, directed the issue of a proclamation that for the successes of Quadratus and Corbulo the laurel was to be added to the imperial "fasces." I have closely connected these events, though they extend into another consulship.
