Now Astyages, watching their furious onslaught, and seeing the enemy move steadily forward in close array to meet them, decided to advance without a moment's delay himself, for fear that his son and Cyrus might come to harm, crashing in disorder against the solid battalions of the foe. [23] The Assyrians saw the movement of the king and came to a halt, spears levelled and bows bent, expecting that, when their assailants came within range, they would halt likewise as they had usually done before. For hitherto, whenever the armies met, they would only charge up to a certain distance, and there take flying shots, and so keep up the skirmish until evening fell. But now the Assyrians saw their own men borne down on them in rout, with Cyrus and his comrades at their heels in full career, while Astyages and his cavalry were already within bowshot. It was more than they could face, and they turned and fled. After them swept the Medes in full pursuit, and those they caught they mowed down, horse and man, and those that fell they slew. There was no pause until they came up with the Assyrian foot. [24] Here at last they drew rein in fear of some hidden ambuscade, and Astyages led his army off. The exploit of his cavalry pleased him beyond measure, but he did not know what he could say to Cyrus. It was he to whom the engagement was due, and the victory; but the boy's daring was on the verge of madness. Even during the return home his behaviour was strange; he could not forbear riding round alone to look into the faces of the slain, and those whose duty it was could hardly drag him away to lead him to Astyages: indeed, the youth was glad enough to keep them as a screen between himself and the king, for he saw that the countenance of his grandfather grew stern at the sight of him.
