The Persian position, both at Thermopylæ and Artemisium, was at this moment very precarious. The army had conspicuously failed to force the pass, and the fleet had, so far, confined itself to the defensive. Cf. H. viii. 15, ad init. Doubtless, urgent messages were coming from Thermopylæ to Aphetæ, commanding that the strait should be forced at any price. 20th day. The Persian commanders, therefore, afraid to defer longer the attack, took the offensive. It may well be that the disadvantages of the position at Aphetæ from a defensive point of view, which had been clearly demonstrated in the engagements of the two previous days, had something to do with determining their course of action. The battle which ensued was an obstinate one. It certainly was not favourable to the Greeks, even less favourable, perhaps, than is represented. H. viii. 16. The losses on both sides were large, those of the Persians being the greater. It seems, however, that, over and above the vessels actually destroyed, H. viii. 18. a large number were considerably damaged, and that the Athenian contingent suffered especially in this respect. H. viii. 19, 20. The account which Herodotus gives of the events which took place after the battle leaves it uncertain whether he considered that the subsequent retirement from Artemisium was due primarily to the losses incurred in the previous engagement, or to the receipt of the news of the disaster at Thermopylæ. Diod. xi. 13. Diodorus mentions the losses, but ascribes the retreat entirely to the news from Thermopylæ. That disaster must have taken place early in the afternoon: the news of it must have reached the fleet at Artemisium, by means of the despatch-boat, very early in the evening. H. viii. 21. According to Herodotus, the retreat had been discussed before the despatch-boat arrived.[147] That it had been discussed may well have been the case; but that it had been decided, and, above all, that Themistocles had consented, to retire that very night, before the receipt of the news from Thermopylæ, is doubtless untrue. Herodotus’ assertion incurs all the more suspicion from the fact that he uses it as a peg whereon to hang a tale illustrative of the disaster which is sure to befall those who refuse to obey the advice of oracles. The Eubœans, he says, had disregarded an oracle of Bakis, which had urged them to place their sheep in security, in view of the coming war, and were now, on the approaching retirement of the Greek fleet, in a position of extreme difficulty as to the best means of saving their property. Themistocles’ proposal for dealing with the situation was simple and effective. He said, “Kill the sheep: kindle fires: roast them and put them on board, since it is better that they fall into our hands than into those of the enemy. As to getting the fleet away in safety, I will look to that.” He also hinted that he had a plan, which he did not then disclose, for detaching the Ionians and Carians from the Persian fleet. So the other Greek commanders looked to the sheep and the fires, while he devised measures for retreat.
No tale could be more peculiarly illustrative of the wide distinction which must be drawn between the facts of history as stated by Herodotus and the motives which he propounds for certain courses of action.
It is doubtless perfectly true that a council of war was held that evening, at which it was decided to retire from Artemisium; and that Themistocles concurred in that decision. But, on the question of motive, it may be taken as almost equally certain that this decision was not come to in consequence of what had happened in the engagement of that afternoon, but by reason of the news which had come from Thermopylæ, which rendered the further presence of the fleet at Artemisium not merely unnecessary, but, from the point of view of the Greek commanders, unadvisable. In actual fact it may be regarded as exceedingly doubtful whether Xerxes could have advanced southwards without the aid of the fleet commissariat; but the idea uppermost in the minds of the Greek commanders would be the extreme danger of such a move on his part.
GREEKS RETIRE FROM ARTEMISIUM.
It is not difficult to see that the building of the fires that evening on the Artemisium shore had probably little if any connection with the provisioning of the fleet, but was part of the plan by which Themistocles proposed to secure a safe withdrawal from the position. The Persians were evidently to be deluded by the idea that the Greeks had no intention of deserting their station; and the ruse employed to attain this end would naturally suggest itself. It has been again and again employed under similar circumstances.
The retreat began early in the night, the ships taking their departure in order according to their position at the anchorage. H. viii. 21. The fact that the Corinthians led the way, and that the Athenians were last to start, may merely signify that they formed respectively the extreme left and right of the line; but, in view of the attitude of the former at this time, it may be suspected that Herodotus had special motives for mentioning the order of retirement.
Themistocles, with a fast sailing division, formed the rearguard. He did not, apparently, intend so much to cover the retreat, as to visit the various watering-places on the shores of the Euripus, and to affix there a quasi-manifesto to the Ionian Greeks in the Persian fleet, calling upon them to abstain, in so far as possible, from attacking their fellow-countrymen. H. viii. 22. His object was, says Herodotus, either to detach the Ionians from their allegiance to Xerxes, or to make the king suspicious of their loyalty.
The Persians did not attempt to pursue the Greek fleet. «H. viii. 23.» The latter had, indeed, got a long start before its departure was discovered. A Greek from North Eubœa brought the news to Aphetæ; but his information was distrusted, and ships were sent across the strait to discover whether it was true or not. This must have taken place during the night, for it was at sunrise that the Persian fleet, after receiving the report of the scouting vessels, moved across the strait to Artemisium. At midday the Persians moved to Histiæa, where they appear to have spent some time in ravaging the district in its neighbourhood.
It is probable that the news of the disaster in the South Euripus deterred the Persians from any attempt at pursuit. Nothing is said as to how or when the news reached them; but it may be regarded as certain that the tidings, which had arrived at Artemisium twenty-four hours before, had in the interval made their way across the strait.
It was now possible for the Persian fleet to communicate by sea with the captors of Thermopylæ; and it may easily be imagined that no time was lost in sending supplies to the army. In connection with these communications Herodotus relates a tale to the effect that Xerxes invited the sailors to view the scene of battle, and took certain ridiculously ineffective measures to conceal from them the magnitude of the losses suffered. That the king did attempt to conceal the greatness of the price he had paid for the capture of the pass may well have been the case; but whether Greek tradition, with its marked tendency to bring into high relief the childishness and foolishness of the Oriental monarch, truly represented the measures taken to attain this end, may well be doubted.
