We must remember, too, in reading the accounts of these transactions, that it is only the Greek side of the story that we hear. The Persian narratives have not come down to us. At any rate, the Persian army was defeated, and that, too, without the assistance of the phalanx. The horsemen and the light troops were alone engaged. The phalanx could not be formed, nor could it act in such a position. The men, on emerging from the water, had to climb up the banks, and rush on to the attack of an enemy consisting of squadrons of horse ready to dash at once upon them.
