A case, however, soon occurred, in Oretes's treacherous and bloody career, which arrested the attention of Darius and aroused his ire. Darius had sent a messenger to Oretes, with certain orders, which, it seems, Oretes did not like to obey. After delivering his dispatches the bearer set out on his return, and was never afterward heard of. Darius ascertained, to his own satisfaction at least, that Oretes had caused his messenger to be waylaid and killed, and that the bodies both of horse and rider had been buried, secretly, in the solitudes of the mountains, in order to conceal the evidences of the deed. Darius determined on punishing this crime. Some consideration was, however, required, in order to determine in what way his object could best be effected. The province of Oretes was at a great distance from Susa, and Oretes was strongly established there, at the head of a great force. His guards were bound, it is true, to obey the orders of Darius, but it was questionable whether they would do so. To raise an army and march against the rebellious governor would be an expensive and hazardous undertaking, and perhaps, too, it would prove that such a measure was not necessary. All things considered, Darius determined to try the experiment of acting, by his own direct orders, upon the troops and guards in Oretes's capital, with the intention of resorting subsequently to an armed force of his own, if that should be at last required. He accordingly called together a number of his officers and nobles, selecting those on whose resolution and fidelity he could most confidently rely, and made the following address to them: "I have an enterprise which I wish to commit to the charge of some one of your number who is willing to undertake it, which requires no military force, and no violent measures of any kind, but only wisdom, sagacity, and courage. I wish to have Oretes, the governor of Sardis, brought to me, dead or alive. He has perpetrated innumerable crimes, and now, in addition to all his other deeds of treacherous violence, he has had the intolerable insolence to put to death one of my messengers. Which of you will volunteer to bring him, dead or alive, to me?" This proposal awakened a great enthusiasm among the nobles to whom it was addressed. Nearly thirty of them volunteered their services to execute the order. Darius concluded to decide between these competitors by lot. The lot fell upon a certain man named Bagaeus, and he immediately began to form his plans and make his arrangements for the expedition.
