Cyropaedia

When they had dined, he led out his army[*](The volunteers to follow Cyrus) while it was still daylight, and he bade the Hyrcanians wait for him that they might go together. Now the Persians, as was to be expected, came out to a man to go with him, and Tigranes came with his army;

while of the Medes some came out because as boys they had been friends of Cyrus when he was a boy, others because they liked his ways when they had been with him on the chase, others because they were grateful to him for freeing them, as they thought, from great impending danger, and still others because they cherished the hope that as he seemed to be a man of ability he would one day be exceedingly successful and exceedingly great besides; others wished to requite him for some service he had done for them while he was growing up in Media; many, too, owed to his kindness of heart many a favour at the hands of his grandfather; and many, when they saw the Hyrcanians and when the report spread that these would lead them to rich plunder, came out (apart from other motives) for the sake of getting some gain.

The result was that almost all came out—even the Medes, except those who happened to be feasting in the same tent with Cyaxares; these and their subordinates remained behind. But all the rest hastened out cheerily and enthusiastically, for they came not from compulsion but of their own free will and out of gratitude.

And when they were out of the camp, he went[*](He assigns the order of marching) first to the Medes and praised them and prayed the gods above all things graciously to lead them and his own men, and he prayed also that he himself might be enabled to reward them for this zeal of theirs. In concluding, he stated that the infantry should go first, and he ordered the Medes to follow with their cavalry. And wherever they were to rest or halt from their march, he enjoined it upon them that some of their number should always come to him, that they might know the need of the hour.
