Anabasis (1.10.10-1.10.14)

But while they were taking counsel about this matter, the King had already changed his line of battle to the same form as theirs and brought it into position opposite them, just as when he had met them for battle the first time.[*] And when the Greeks saw that the enemy were near them and in battle-order, they again struck up the paean and advanced to the attack much more eagerly than before;

and the barbarians once again failed to await the attack, but took to flight when at a greater distance from the Greeks than they were the first time.

The Greeks pursued as far as a certain village, and there they halted; for above the village was a hill, upon which the King and his followers rallied; and they were not now foot-soldiers, but the hill was covered with horsemen, so that the Greeks could not perceive what was going on. They did see, they said, the royal standard, a kind of golden eagle on a shield, raised aloft upon a pole.

But when at this point also the Greeks resumed their forward movement, the horsemen at once proceeded to leave the hill; they did not keep together, however, as they went, but scattered in different directions; so the hill became gradually cleared of the horsemen, till at last they were all gone.

Clearchus, accordingly, did not lead the army up the hill, but halted at its foot and sent Lycius the Syracusan and another man to the summit, directing them to observe what was beyond the hill and report back to him.
