[28] So the two armies drew nearer and nearer, and when they were about four miles apart, the Assyrians proceeded to encamp in the manner described: their position was completely surrounded by a trench, but also perfectly visible, while Cyrus took all the cover he could find, screening himself behind villages and hillocks, in the conviction that the more sudden the disclosure of a hostile force the greater will be the enemy's alarm.
[29] During the first night neither army did more than post the customary guards before they went to sleep, and on the next day the king of Assyria, and Croesus, and their officers, still kept the troops within their lines.

But Cyrus and Cyaxares drew up their men, prepared to fight if the enemy advanced.
Ere long it was plain that they would not venture out that day, and Cyaxares summoned Cyrus and his staff and said: [30] "I think, gentlemen, it would be well for us to march up to the breastworks in our present order, and show them that we wish to fight.
If we do so," he added, "and they refuse our challenge, it will increase the confidence of our own men, and the mere sight of our boldness will add to the enemy's alarm." [31] So it seemed to Cyaxares, but Cyrus protested: "In the name of heaven, Cyaxares, let us do no such thing.

By such an advance we should only reveal our numbers to them: they would watch us at their ease, conscious that they are safe from any danger, and when we retire without doing them any harm they will have another look at us and despise us because of our inferiority in numbers, and to-morrow they will come out much emboldened.

[32] At present," he added, "they know that we are here, but they have not seen us, and you may be sure they do not despise us; they are asking what all this means, and they never cease discussing the problem; of that I am convinced.

They ought not to see us until they sally out, and in that moment we ought to come to grips with them, thankful to have caught them as we have so long desired." [33] So Cyrus spoke, and Cyaxares and the others were convinced, and waited.
