(8) Then Gobryas brought back the words of the king to Cyrus, and Cyrus led his army off, and then he summoned Gobryas and said to him:

"Surely you told me that you thought the man who was made an eunuch by the king would be upon our side?"

"And I am sure he will," answered Gobryas, "for we have spoken freely to each other many a time, he and I." (9) "Then," said Cyrus, "you must go to him when you think the right moment has come: and you must so act at first that only he and you may know what he intends, and when you are closeted with him, if you find he really wishes to be a friend, you must contrive that his friendship remain a secret: for in war a man can scarcely do his friends more good than by a semblance of hostility, or his enemies more harm than under the guise of friendship." (10) "Aye," answered Gobryas, "and I know that Gadatas would pay a great price to punish the king of Assyria. But it is for us to consider what he can best do." (11) "Tell me now," rejoined Cyrus, "you spoke of an outpost, built against the Hyrcanians and the Sakians, which was to protect Assyria in time of war,—could the eunuch be admitted there by the commandant if he came with a force at his back?" "Certainly he could," said Gobryas, "if he were as free from suspicion as he is to-day." (12) "And free he would be," Cyrus went on, "if I were to attack his strongholds as though in earnest, and he were to repel me in force. I might capture some of his men, and he some of my soldiers, or some messengers sent by me to those you say are the enemies of Assyria, and these prisoners would let it be known that they were on their way to fetch an army with scaling-ladders to attack this fortress, and the eunuch, hearing their story, would pretend that he came to warn the commandant in time." (13) "Undoubtedly," said Gobryas, "if things went thus, the commandant would admit him; he would even beg him to stay there until you withdrew."

"And then," Cyrus continued, "once inside the walls, he could put the place into our hands?" (14) "We may suppose so," said Gobryas. "He would be there to settle matters within, and you would be redoubling the pressure from without."

"Then be off at once," said Cyrus, "and do your best to teach him his part, and when you have arranged affairs, come back to me; and as for pledges of good faith, you could offer him none better than those you received from us yourself."

(15) Then Gobryas made haste and was gone, and the eunuch welcomed him gladly; he agreed to everything and helped to arrange all that was needed. Presently Gobryas brought back word that he thought the eunuch had everything in readiness, and so, without more ado, Cyrus made his feigned attack on the following day, and was beaten off. (16) But on the other hand there was a fortress, indicated by Gadatas himself, that Cyrus took. The messengers Cyrus had sent out, telling them exactly where to go, fell into the hands of Gadatas: some were allowed to escape—their business was to fetch the troops and carry the scaling-ladders—but the rest were narrowly examined in the presence of many witnesses, and when Gadatas heard the object of their journey he got his equipment together and set out in the night at full speed to take the news. (17) In the end he made his way into the fortress, trusted and welcomed as a deliverer, and for a time he helped the commandant to the best of his ability. But as soon as Cyrus appeared he seized the place, aided by the Persian prisoners he had taken. (18) This done, and having set things in order within the fortress, Gadatas went out to Cyrus, bowed before him according to the custom of his land, and said, "Cyrus, may joy be yours!"

(19) "Joy is mine already," answered he, "for you, God helping you, have brought it to me. You must know," he added, "that I set great store by this fortress, and rejoice to leave it in the hands of my allies here. And for yourself, Gadatas," he added, "if the Assyrian has robbed you of the ability to beget children, remember he has not stolen your power to win friends; you have made us yours, I tell you, by this deed, and we will stand by as faithfully as sons and grandsons of your own."

(20) So Cyrus spoke. And at that instant the Hyrcanian chief, who had only just learnt what had happened, came running up to him, and seizing him by the hand cried out:

"O Cyrus, you godsend to your friends! How often you make me thank the gods for bringing me to you!"

(21) "Off with you, then," said Cyrus, "and occupy this fortress for which you bless me so. Take it and make the best use of it you can, for your own nation, and for all our allies, and above all for Gadatas, our friend, who won it and surrenders it to us."
