Even cowards had been mobilised; or rather — which was not necessarily the same thing — men whom the Spartans had labelled cowards. One of these, an unfortunate veteran by the name of Aristodemus, was particularly grateful to have been given a chance to redeem his honour, for this was not the first time that he had marched to war against the barbarians. Less than a year previously, he had been one of the three hundred who had accompanied Leonidas to Thermopylae. Arriving at the pass, he and a fellow Spartan had fallen sick with an eye inflammation, and the two men had been dismissed and ordered to recuperate. Come the fateful morning of their king's last stand, however, Aristodemus' partner, rising from his sick-bed, had instructed a helot to lead him, blind as he still was, into the thick of the fighting. Aristodemus, preferring to obey Leonidas' direct orders, had invalided himself home. There, on his arrival, he had been greeted with revulsion. His fellow citizens had branded him 'trembler': the single most shameful word in the Spartan lexicon.
Harshly unfair — but it was only to be expected, in a city where courage was reckoned the greatest virtue, that the slightest hint of cowardice in a citizen would doom him to ignominy. The life of a 'trembler' in Sparta was signally wretched. Patches sewn onto his cloak would alert the whole city to his disgrace. Whether sitting down at his mess-table or attempting to join in with a ball-game, he would be icily ignored by all his former friends. At festivals, he would have to stand up or make way for anyone who demanded it — even the most junior. Cruellest cut of all, his daughters, if he had any, would find it impossible to secure a husband: a typically Spartan eugenicist measure designed to prevent the taint of cowardice from being inherited by future generations. Unable to endure these humiliations, the only other survivor of Thermopylae, a liaison officer sent by Leonidas on a mission to Thessaly, had ended up hanging himself. 'For after all, when cowardice results in such shame, it is only to be expected that death be preferred to a life of dishonour and obloquy.
And for Aristodemus, the man who had spurned the chance to die in battle beside his king, the long months following his return from Thermopylae had been particularly bitter. The shadow cast by Leonidas' end had proved impossible to escape. Mourning in Lacedaemon was not, as it was in, say, Athens, the responsibility only of women. Every man too, whether ephor or helot, was obliged to wail and beat his brow when a king descended to the underworld. To other Greeks, indeed, Spartan lamentations appeared so excessive as to verge on the barbarian. Officially, the obsequies that accompanied a royal funeral lasted for ten days, but Leonidas was no easy ghost to lay to rest. His mutilated corpse, left as food for kites and dogs in a far-distant pass, had never been recovered. Adding to the pathos of his fate, and a constant reminder to the Spartan people of the loss they had sustained, was the fact that his son, the new king, was just a boy. Cleombrotus, Leonidas' younger brother, had been serving ably as regent but he, too, during the course of the winter, had died. When the Spartans, then, having resolved to give battle at last, marched out from the Isthmus, they did so under the generalship of a young man barely in his twenties: Pausanias, the son of Cleombrotus. Since he was, as the Regent of Sparta, also the supreme commander of the allied forces, this was a startling weight of responsibility for one so young to bear — but Pausanias himself, whose qualities as a general never entirely outpaced his conceit, shouldered it with insouciance. Even so, the brute fact of their general's youth must have kept Thermopylae, and Leonidas' death there, all the more firmly in the Spartans' minds. Marching to liberate Greece, they were also after revenge. And Aristodemus especially — for it was due to the barbarians that he wore his trembler's patchwork cloak.
And there were others, too, of course, who wanted payback — men whose losses had been infinitely greater than the Spartans'. At Eleusis, thirty-five miles along the coastal road from the Isthmus, Pausanias waited while Aristeides and eight thousand other Athenians ferried themselves across from Salamis. Also joining the expedition were six hundred exiles from a second city occupied and torched by the invaders: Plataea. Now at last, a year after fleeing their homeland, the cherished moment of return had finally arrived. It was time for the Plataeans, and for everyone else committed to meeting with the barbarian, to take the road to Boeotia.
Heading northwards, the allies duly left Eleusis. Soon enough, dusty ridges of limestone and slopes of mangy brushwood began to obstruct any backward glances at the sea. As the advance progressed, so the way ahead of the tramping hoplites turned increasingly rugged, the valleys lonely, the fir-dotted slopes of Mount Cithaeron even more so, the haunt not of men but of wild beasts, deer and bears and lions — and sometimes, for he loved all such deserted spots, of the great god Pan himself. In happier times, the Boeotians had been accustomed to celebrate an eerie festival, wheeling colossal idols of wood from the banks of the Asopus, hauling them all the way up the side of the mountain, and then, at the very summit, incinerating them, so that the conflagration might be seen for miles around, a beacon lit for the gods. The Plataeans, surely, passing beneath the austere heights of Mount Cithaeron, would have pressed ahead now with particular eagerness, for they were just hours away from their city; and the road, after winding past spurs and jagged crags, suddenly opened out, giving them, away to their left, a view at last of their beloved homeland.
But not as they had left it. Their fields were overgrown and their city a blackened shell. Trees for miles around had been levelled. Stripped and raw, the timbers now formed the barbarians' palisade. Meanwhile, the barbarians themselves, their numbers appearing to slur together in the shimmering heat, swarmed across the plain, and everywhere, it seemed, there were horses, whether hobbled, or in corrals, or else being ridden across the parched dirt of Boeotia, plume-shadowed as they flaunted their speed and proficiency. There could have been few among the Greeks who did not feel a tremor of consternation at such a sight; and Pausanias himself, who was arrogant but certainly not foolhardy, had not the slightest intention of crashing down directly to confront the enemy on ground so favourable to their cavalry. Instead, sternly ordering his men to keep to the foothills, he then manoeuvred them into a position roughly opposite Mardonius' forces — not only above but some seven miles to the east of Plataea. For the city's six hundred hoplites, the return to what remained of their homes was evidently going to be delayed.
Yet, though Pausanias was proving himself to be cautious, it is unlikely that his first sight of the Persian forces had prompted anything like the alarm that Mardonius must have experienced when he looked up from the banks of the Asopus and saw the full scale of the army snaking across the foothills above him. His agents had certainly brought him some reports of the allied preparations. For days, the mood among the high command had been jittery. At a dinner-party hosted by a prominent Theban collaborator, for instance, a Persian officer had turned to his Greek neighbour and whispered that of all the guests around them, and of all the troops camped beside the river, 'you will see, in a short time, only a very few left alive'.

Mardonius himself would never have admitted to such defeatism; but neither, not even at his most pessimistic, would he have imagined the ever-fractious allies capable of co-ordinating a task force such as was now being brought to bear against him on the lower slopes of Mount Cithaeron. On and on, throughout the day, the Greeks descended from the pass, taking up their positions, until, by the time that they were finally embedded, Mardonius found that he was staring at the largest hoplite army ever assembled in a single place: almost forty thousand men.
48
Against these fearsome numbers, he himself could muster perhaps twice as many again; but he would have had no illusions that his infantry, only lightly armed and armoured, could hope to overrun the Greek positions.
49
Instead, only two options appeared to give him any real prospect of victory. The first was somehow to lure the allies down to the plain, and then to trust that their various contingents, unaccustomed as they were to fighting side by side, would blunder apart and prove easy meat for his cavalry. The second was to sow divisions among the enemy ranks with a strategic deployment of bribes, and then to wait for the endemic rivalries that afflicted all Greek coalitions to take hold. Horsemen and spies: the deadliest weapons, as they had ever been, in the Persian armoury.
And Mardonius, looking to co-ordinate their deployment, decided that his first move should be to resume the war of nerves that he had been waging all summer against the Athenians. The Spartans, it would soon emerge, had been right to suspect a canker of medism in the refugee camps on Salamis. The murdered Lycidas had not been alone in his pro-Persian views. Other prominent citizens, ruined by the war, resentful of the democracy, hungering to restore their lost fortunes, had also been plotting; and not merely appeasement, but naked treachery. Mardonius, who had lost contact with these collaborators following his withdrawal from Attica, would surely have looked to re-establish communications with them as a matter of urgency; simultaneously, hoping to concentrate the traitors' minds even as he dispatched agents to infiltrate their camp, he ordered his cavalry to launch a hit-and-run raid on the allied lines.
A cunningly crafted pincer attack - except that it did not go entirely according to plan. First, far from demoralising the Greeks, the cavalry raid served only to boost their morale: for the Persian commander, a hulking dandy who had ridden into battle sporting a purple tunic and an eye-catching cuirass of golden fish-scales, had his Nisaean horse shot from under him and ended up dead and exposed on a wagon, being paraded before the gawping allied troops. Shortly afterwards, the treachery in the Athenian camp was uncovered by Aristeides, who, deciding that he could hardly ignore the plot but not wishing to stick his nose too far into the ordure, contented himself with arresting only the eight most prominent conspirators.
50
Two of these fled; the other six, ordered to redeem themselves in the coming battle, were released without charge. Aristeides, who had himself been labelled a Mede-lover when ostracised, knew perfectly well what it was to be given a second chance. There was no more talk of treachery, from that moment on, in the Athenian camp.
Yet these setbacks, rather than crippling Mardonius' strategy, served ironically to give it a second wind. Pausanias, his spirits much boosted, felt sufficiently emboldened to take up a new position, much closer to the Asopus, and therefore to the enemy. Mardonius, hoping to catch the Greeks on open ground, immediately began to hurry along the opposite bank, shadowing them, waiting for a chance to strike. It never came. Pausanias, even as he inched onto the plain, had been sure to move sideways into the territory of Plataea, and there was not a spur along the route he took, not a stretch of elevated ground, but the Plataeans were able to guide the allies along it. By the time that their dispositions had been completed, the Spartans were dug in along a broken ridge on the right of the battle-line, and the Athenians were installed on a hillock on the left. The remaining contingents, led by men whose clout could hardly compete with that of Pausanias or Aristeides when it came to securing the safest billets, had to be content with occupying the lower — and therefore more exposed — ground in the centre. Mardonius, eyeing up his opportunities from the opposite side of the Asopus, must have felt a quickening of excitement. He may not yet have been in a position to launch a frontal attack — for the fields of Plataea, even at their flattest, still undulated menacingly— but if he could just tempt Pausanias to continue his advance across the river, the Persian cavalry would have him. Mardonius was a practised Greek-fighter; he knew that the instinct of a hoplite army was always to seek out battle. So when the heavens themselves, speaking through incontrovertible omens, warned the Persian high command not to go on the attack, Mardonius was more than content to listen. Time appeared to be on the side of a policy of wait-and-see: barely five miles away, in Thebes, 'food was in abundance, including fodder for the animals'" and Mardonius had reserves of treasure enough to flood the whole Greek camp with gold. He did as the gods had advised: he kept to the north bank; he did not cross the river.
But nor did Pausanias. Instead, blunting all Mardonius' expectations of how a Greek general would behave, he kept grimly to his position. The Spartans clung to their ridge, the Athenians to their hill, everyone else to the fields in between. Although squabbles would periodically erupt between the various contingents — and particularly when the Athenians started throwing their weight around — the feuding never escalated so as to threaten the alliance itself with disintegration. Indeed, far from fracturing, the Greek battle-line grew ever stronger: for as first a day passed, and then another, and ultimately a whole week, reinforcements kept trickling in. Eventually, on the eighth day of the stand-off, Mardonius lost his patience. His cavalry were ordered to make a raid on the Cithaeron passes. A huge wagon train, loaded down with provisions from the Peloponnese, was successfully ambushed. The drovers and mules alike were massacred. Then, leaving the corpses to litter the foothills where they would be clearly visible to the Greeks down on the plain, the Persians, 'once they were sated of slaughter', drove the wagons back in triumph to their camp.
