Of the destination of the two hundred the Greeks do not appear to have had any suspicion whatever, until Skyllias the diver, deserting the Persian fleet, made his way across the strait and gave them information. The utter confusion of this part of the Artemisium story renders it very difficult to arrive at anything resembling a certain conclusion as to what actually took place in consequence of the receipt of this news. It is hardly conceivable that those in command of the Greek fleet should have been quite unprepared for the eventuality of a squadron being sent round to intercept their retreat by Chalkis. There is no direct evidence on this point; the slight evidence which does exist is of a circumstantial character. ◆H. viii. 14.◆ After describing the disaster which overtook the two hundred vessels, Herodotus says that the news of it was brought to the fleet at Artemisium by a squadron of fifty-three Attic vessels, or, at any rate,—for his language is not quite explicit,—that the news arrived with that squadron. This is the first mention of this body of ships. It seems highly probable that it had been at Chalkis, guarding the narrow passage there, and that, on receiving news of the disaster to the Persian flying squadron, it went to join the rest of the fleet at Artemisium. The escape of Skyllias is asserted to have been made during the review, and the consultation among the Greeks as to what course they must adopt in consequence of his information was held on the day of the first engagement.[138] Herodotus reports that they determined to remain where they were for that day and the greater part of the following night, and then, after midnight, to go and meet the ships coming up through the south channel. It is quite intelligible that, if the Greeks had not provided for the defence of the narrows at Chalkis, their position was such as to cause alarm, and to demand desperate measures. But the probability is that there never was any intention on the part of the Greek commanders to leave the station at Artemisium until some blow had been inflicted on the fleet at Aphetæ.[139] The Attic vessels were probably guarding the strait, which at Chalkis was so narrow as to be easily defensible. Under no circumstances could the fleet at Aphetæ have been left free to land troops behind Thermopylæ.[140] #ATTACK ON PERSIANS AT APHETÆ.#
