eam tamen legionem quam exauctoravit rogatus post dies XXX, priusquam ad expeditionem Persicam proficisceretur, loco suo restituit eaque pugnante maxime vicit, cum tamen tribunos eius capitali adfecit supplicio, quod per neglegentiam illorum milites apud Daphnem luxuriati essent, vel per coniventiam seditionem fecisset exercitus.
Translation :
However, thirty days afterwards, before he set out on the campaign against the Persians, he was prevailed upon to restore the discharged legion to its former status; and it was chiefly through its prowess in the field that he won the victory. Nevertheless, he inflicted capital punishment on its tribunes because it was through their negligence that the soldiers had revelled at Daphne or else with their connivance that the troops had mutinied.
