Upon Ptolemy's fall and the rout of his company, the Spartans pursued, carrying all before them, and before they were aware of it had dashed out into the plain and were cut off by the infantry of Pyrrhus. Against this band of Spartans Pyrrhus, who had just heard of the death of his son and was in anguish, turned his Molossian horsemen. He himself charged at their head, and sated himself with Spartan blood. He had always shown himself invincible and terrible in arms, but now his daring and might surpassed all previous displays.
