Though Valens initially despaired of subduing the rebellion, and was inclined to come to terms with the usurper, he quickly rallied, guided by the counsels ofSalutiusandArintheus, and the superior ability of his generals prevailed in two battles atThyatiraandNacoliawhere Procopius' forces were defeated. He fled the battlefield, and was for a while a fugitive in the wilds ofPhrygia, but was soon betrayed to Valens due to the treachery of his two generals Agilonius andGomoarius(they had been promised they would be "shown favour" by Valens), he was captured. Valens had his rival executed on 27 May 366 by being fastened to two trees bent down with force; when the trees were released, Procopius was ripped apart in the manner of the legendary execution of the banditSinis. The "favour" Valens showed to Agilonius and Gomoarius was to have them bothsawn asunder.
