The enemy line faltered, its front ranks stopping dead. The rearward Persian marchers, unable to see what was happening uphill beyond their leading comrades, kept pushing forward, tripping over those who had halted in front, and in turn being pushed by their fellows in the rear. Encouraged at this sign of hesitation, the Greek heavy infantry picked up its pace to a full sprint, armor and shields crashing madly. The discipline of the Greek forces was heart-stopping-men prepared against those unprepared, good order against disorder, troops surging forward in absolute, deadly precision, as tight and as uniform as the scales on an asp.
As for what happened next, it is impossible to say whether the gods were responsible, or whether no enemy could resist a tide of men as determined as ours. The Persian ranks collapsed without a struggle in the face of the Greek hell-storm, unable to muster even the deafening crash one usually hears as the lead warriors of the opposing forces collide and fold into one another in a chaos of metal, body fluids, and screams. The front line broke and we plowed over them as if they were so many molehills, neglecting even to kill those we ran over, but simply trampling them and moving on to the next rank, a seething, roaring wall of iron and death. The frenzied camp followers swarming close behind us stripped the dead of their valuables and food, using clubs and discarded spearheads to make short work of any enemy soldiers who remained twitching or sobbing after being mowed down by our surging hoplites. The Persians in the front lines tried desperately to wheel and run to the rear, but their comrades behind, fifteen or twenty ranks thick, marched doggedly forward like the slaves they were, under the whips and threats of their sergeants, blocking the path of the panic-stricken front ranks and hindering their retreat. Slaughter ensued, panic fed upon panic. Even those few Persians originally inclined to take a stand and fight lost heart when they saw they had been deserted on all sides, and then they themselves joined the terrified mob.
Our archers took special aim at the enemy chariot drivers, who had held slightly back behind their heavy infantry, waiting for a gap in the fighting to open up through which they could drive their lethal scythes without cutting apart their own men. The Spartans loathed such machines, and had not used them in their own forces for a hundred years. They did, however, relish the thought of facing them, for they had mastered the trick of calmly opening up gaps between which the chariot drivers would charge harmlessly, while one or two Spartans darted in from the side and stabbed the horse or driver. In his youth, Clearchus was known to be well accomplished in this trick.
The Spartans were to be disappointed, however, for not a single Persian scythe-chariot even made it to the Greek lines. Our bowmen toppled several of the drivers, and in the ensuing chaos none of the Persian infantry even bothered to pick up their comrades' reins. The panicked horses raced about aimlessly among their own men, the razor-sharp blades violating the sanctity and virginity of fragile skin, lopping off an arm here, a head there, gouging through men's breastplates and ribs as if they were cheese, exposing the gods' secrets to the eyes of leering and terrified onlookers. I watched as two Boeotians from Proxenus' battalion, brothers as it happened, each took charge of a runaway chariot and began lending method and discipline to the general carnage they were wreaking, turning the Persians' most terrifying weapons against them with devastating effect. They cut a bloody swath through the most densely packed of the enemy lines, and then calmly drove their captured trophies up to Proxenus, grinning, with odd pieces of bloody flesh and dripping helmet leather still hanging off the murderous tines. Socrates once said that to peer inside a human being, you can make him laugh or observe him in love; he neglected to note that you can also use a blade or a spear point. The latter method proves beyond a doubt that people are more alike inside than they are outside, and in fact are scarcely different from pigs or asses.
Xenophon galloped back and forth the length of our immediate line, wheeling his mount in tight circles at the end of his range, and observing Tissaphernes' forces closely for any indication of an attack or an attempt to outflank our troops. The exercise was useless, however; Tissaphernes' cavalry were helpless in the chaos, and they assembled nervously far to the rear of the battle, awaiting the outcome. I glanced at Proxenus, who was darting in and out of the slaughter on his horse, trying to maintain order among the fury, and at Clearchus, who after having led his men directly to the enemy lines, had backed away to monitor the situation, and was now sitting on his horse impassively on the edge of the fray, watching as his men mowed down the enemy as if harvesting wheat in a field.
Finally the Persians' surviving middle and rear ranks reversed their march and began a general retreat. The Greeks ran them down as they went, tripping over the bodies of the fallen and slipping in the gore on the ground as they churned it into an ankle-deep slurry of mud and piss, salted with shattered weapons and the detritus of dying men. The Hellenes' spears, both the throwing point and the sauroter, the bronze-tipped "lizard-killer" used for standing the weapon in the ground when at rest, had long since broken and shivered on the fragile spines and skulls of the Persians, and our men were now reduced to a frenzied, blind hacking with their short swords. Mobs of Persians threw down their shields and weapons in their panic, forgoing any protection, forgetting even to fight, but doing everything to assist in their own slaughter. The enemy dead numbered in the thousands, while our troops had scarcely lost a man, suffering only from the weary numbness in our limbs from the strain of the relentless killing.
Clearchus at last roused himself from his apparent boredom at the appalling carnage, and ordered his trumpeter to sound a halt. For what seemed an eternity, nothing happened. The horrifying bloodbath continued unabated. Finally, however, after further trumpet blasts, Clearchus resorted to riding into the slaughter himself, swinging and beating at his own men with the flat of his sword to drive them back, to force a respite. The mad blood-trance lifted and the Greeks staggered, gasping, to a halt. The shattered men slowly lowered their arms and stood trembling in place, dropping their weapons in exhaustion. The terrible roar of battle died away to a mere echo in our heads, which was gradually replaced by the moans of the injured and dying. The troops' appearance was hellish, godlike-so slathered in gore from helmet to greaves they might have been wallowing in it like dogs, their eyes glittering evilly through the darkness of their visors, the muscles in their shoulders and thighs swollen and taut. Their chests heaved, quaking legs collapsing in exhaustion, some crumpling into the steaming, fetid muck, kicking aside corpses and unclaimed viscera to make room for themselves. Moans of agony filled the still, heavy air, the death throes of bleeding Persians who had not yet been dispatched by the pitiless camp followers. The ground was purple with blood, it flowed in rivulets into puddles and pools and collected in hollows, corpses lay mingled with each other, shields pierced, spears splintered, daggers unsheathed, some on the ground, most stuck in bodies, some still in the hands of the dead. The hardiest of the Greek troops struggled to remain on their feet, their hands shaking from the shock of the slaughter and the intensity of their effort, and they sought out comrades, even strangers, to lean against in their exhaustion and to feel some human comfort.
