Knowing that the Lusitanian resistance was largely due to Viriathus' leadership, Caepio bribed Audax, Ditalcus and Minurus, who had been sent by Viriathus as an embassy to establish peace (Appian). These ambassadors returned to their camp and killed Viriathus while he was sleeping. Eutropius claims that when Viriathus' assassins asked Q. Servilius Caepio for their payment he answered that "it was never pleasing to the Romans, that a general should be killed by his own soldiers.", or in another version more common in modern Portugal and Spain, "Rome does not pay traitors who kill their chief". Q. Servilius Caepio was refused his Triumph by the Senate.
