This is a very remarkable incident in the narrative of an episode which is itself undeniably one of the most remarkable in history. It contains but little of that reliable element in Herodotus,—fact; it contains much of the unreliable element,—motive. The facts are plain, and there is no reason to doubt them. The Spartans, Thebans, and Thespians remained and took part in the final struggle; the rest of the allies departed. Who were the latter? By reference to the list of those present in the pass it will be found that they were Tegeans, Mantineans, other Arcadians, Corinthians, Phliasians, Mykenæans Paus. ii. 16, 5; x. 20, 2. (though Pausanias mentions a tradition to the effect that they remained), and the Opuntian Locrians. The calculation can only be an approximate one, but, excluding the Phocians, who were up on the path, and the Opuntian Locrians, whose number we do not know, 3500 remained, and 2800 departed.[121] This division is a somewhat significant one.

The central motive in Herodotus’ story is undoubtedly the reported oracle delivered to Sparta “quite early in the war.” It is unfortunate, from the historical point of view, that the tradition assailed the historian on his weakest side. He was incurable in this respect. DIFFICULTIES IN THE NARRATIVE. Even the most glaring cases of oracular dishonesty, to which he could not shut his eyes, such as the tampering of the Alkmæonidæ with the oracle at Delphi in order to bring about the expulsion of the Peisistratidæ, never killed his faith in oracular responses in general. But in cases where, as in the present instance, an oracle came to point a moral and adorn a tale, he completely surrendered his critical faculty. The whole of Herodotus’ narrative hangs by this oracle. He rejects the story that half the army deserted the defence of its own free will, in order, in accordance with his prime motive, to produce a story to the effect that Leonidas dismissed them, knowing that he himself had to make the great act of self-abnegation, and not wishing to involve them therein. And yet Leonidas keeps the Thebans with him, and the Thespians remain of their own free will; and, apparently, he allows them to do so.

If this account be true, what was the position of those three thousand five hundred Greeks who remained to face the Persian attack on front and rear? It is not said that they sacrificed themselves to give their friends time to escape, nor is there the slightest cause to suppose that there was any reason whatever for their doing so. The scouts from the top of the mountain must have been down in the camp at least two hours before the Persians could arrive at the site of Upper Drakospilia; and, even arrived there, the latter could not possibly have descended into the pass before their numbers had gathered. It must have been late in the morning before they came down, and probably past midday before they began to assail the rear of the Greek position. Those who escaped had only a mile and a half to go before they were out of the pass at the east gate; and, once outside, they were in an easy country, over which they could travel rapidly.

Taking the story as it stands, there is no possible strategic motive for remaining to defend the middle gate; there is rather every reason for not doing so. And the men who remained there must have been perfectly aware that by remaining they merely sacrificed their own lives without really contributing anything to the defence of their fatherland. The intense sense of discipline among the Spartans may, in so far as they are concerned, of itself account for an act otherwise inexplicable. But what of the Thebans? Were they likely to allow themselves to be forced to face certain death in a case where none save a sentimental result could be attained, without displaying a feeling such as would make them most undesirable participants in the defence? And the Thespians? They must have amounted to a very large proportion of the total available fighting force of their little town. Were they likely to sacrifice themselves, as has been suggested, in the hope that if the Greek cause prospered, they might become the head of the Bœotian confederacy? How could they hope to attain such a result by deliberately placing seven hundred of their citizens in a position whose only issue was the gate of death? What measure of gratitude could they expect from a people who were responsible for their great betrayal at Thermopylæ?

It is plain that there must have been some reasonable and strong motive which induced the Thespians to remain, and made it possible for the Thebans to be retained with Leonidas. The reason given by Herodotus is inadequate to the last degree. Some other must have existed. It is probable that, as is often the case under such circumstances, part of the true reason is present in some form in the statement of the imagined motives. Two tales existed, so Herodotus says: one that the allies went away; the other that they were sent away. Possibly each of them contained a fraction of the truth. What was the situation on that eventful morning? The news of the Persians having passed the summit came not long after dawn. Leonidas must have known, if he had, as must be supposed, taken any measures to get knowledge of the path, that the Persians could not be in force at Upper Drakospilia, to use the modern name, for some hours after the news reached him; and three thousand men in the tangled forest which begins just outside the village might stop the whole Persian army. He would thus be able to maintain the pass, if he could hold his end of it. DEPARTURE OF HALF THE GREEK ARMY. Is it not possible, then, that he divided his force into what, as has been seen, was, roughly speaking, two halves, and “sent away” the one half to seize the forest path before the Persians had time to debouch from it in any strength? On the question of time it may be said that from the middle gate to Upper Drakospilia is an hour and twenty minutes by the direct but more difficult path, and about twenty minutes longer by the easier path which comes down near the east gate.

It seems an essential factor in the situation that Leonidas believed in and was able to persuade the Thespians and, it may be, the Thebans too, of the possibility of still maintaining the pass. Had the division sent to meet Hydarnes done its duty with energy, it is highly probable, judging from the history of the previous fighting, that the event would have justified his confidence. What happened to that division of two thousand eight hundred men will never be known. It may be that for some reason it arrived too late, and found the Persians in too strong a force at Drakospilia. It may be that it never attempted to carry out the orders, and retreated straightway through the east gate, and so to Elatæa. Probably the latter was the case. Had there been a reasonable excuse for their conduct it would have survived in history. But was there no excuse for their vanishing from the scene? They were face to face with a fearful danger, greater even than the danger which had faced them for a week past, great though that had been. They must have been suffering under a bitter sense of desertion, left to their fate, as it were, by those who sent them from the Isthmus. And who but Sparta was responsible for this? “Had they not done enough?” they may have argued. Were they to blame if, deserted themselves, they deserted others? And who were those “others?” Spartans, men of the race which had wished to sacrifice them; Thebans of suspicious loyalty; Thespians, who were—well, not Peloponnesians. And so they could go off with half a conscience, if not a whole one. Such reasoning would not do them honour; but men, if dishonourably treated themselves, are but too apt, in their bitter resentment, to lose the finer sense of honour.

The story of their shame but half-survived; Herodotus caught some echo of it. Those who lived to tell it had most interest in concealing it. The dead men at Thermopylæ could tell no tales; and the Thebans were too much discredited to obtain credit. There was a conspiracy of silence. The inaction of the Spartan authorities had borne terrible fruit,—far more terrible, it may be believed, than the authorities ever expected it would bear. Leonidas had been deserted and had died with his brave band. It was no good blaming the allies who deserted him, even had it been possible under the circumstances to establish the fact of their desertion. These, too, could have retaliated with a tale which would have brought discredit, or even infamy, on those who were really responsible for the disaster.

Thus it was possible to conceal the truth, and the field was open for invention. It was not difficult to supply a motive for a courage so grand as that which Leonidas had displayed,—the motive of self-sacrifice. That was absolutely the only motive which could account to the world for the extraordinary circumstances of his death; and it had the merit of being true.

He was represented as a victim self-immolated on the altar of his country’s weal. The oracle had said that the king must die for his people. And he did die, but a victim to the dishonour of a country which left him and the brave men with him to their fate.

After the departure of the Peloponnesian allies, the last scene in the tragedy began. H. vii. 223. Herodotus describes it in the simple but beautiful language of a master-artist who seeks to do justice to the grandest story of his time. Xerxes after making libation at sunrise, waited until the time when the Agora is wont to fill, and then began the attack; such being the instructions of Epialtes.[122]
