The endeavours of the deputies of Greeks at the isthmus had thus produced no other reinforcement to their cause except some fair words from the Corcyræans. It was about the time when Xerxes was about to pass the Hellespont, in the beginning of 480 B.C., that the first actual step for resistance was taken, at the instigation of the Thessalians. Though the great Thessalian family of the Aleuadæ were among the companions of Xerxes, and the most forward in inviting him into Greece, with every promise of ready submission from their countrymen—yet it seems that these promises were in reality unwarranted. The Aleuadæ were at the head only of a minority, and perhaps were even in exile, like the Pisistratidæ: while most of the Thessalians were disposed to resist Xerxes—for which purpose they now sent envoys to the isthmus, intimating the necessity of guarding the passes of Olympus, the northernmost entrance of Greece. They offered their own cordial aid in this defence, adding that they should be under the necessity of making their own separate submission, if this demand were not complied with. Accordingly a body of ten thousand Grecian heavy-armed infantry, under the command of the Spartan Euænetus and the Athenian Themistocles, were despatched by sea to Alus in Achaia Phthiotis, where they disembarked and marched by land across Achaia and Thessaly. Being joined by the Thessalian horse, they occupied the defile of Tempe, through which the river Peneus makes its way to the sea, by a cleft between the mountains Olympus and Ossa.
THE VALE OF TEMPE
Greek Standard Bearer
The long, narrow, and winding defile of Tempe formed then, and forms still, the single entrance, open throughout winter as well as summer, from lower or maritime Macedonia into Thessaly. The lofty mountain precipices approach so closely as to leave hardly room enough in some places for a road: it is thus eminently defensible, and a few resolute men would be sufficient to arrest in it the progress of the most numerous host. But the Greeks soon discovered that the position was such as they could not hold—first, because the powerful fleet of Xerxes would be able to land troops in their rear; secondly, because there was also a second entrance passable in summer, from upper Macedonia into Thessaly, by the mountain passes over the range of Olympus. It was in fact by this second pass, evading the insurmountable difficulties of Tempe, that the advancing march of the Persians was destined to be made, under the auspices of Alexander, king of Macedon, tributary to them and active in their service. That prince sent a communication of the fact to the Greeks at Tempe, admonishing them that they would be trodden under foot by the countless host approaching, and urging them to renounce their hopeless position. He passed for a friend, and probably believed himself to be acting as such, in dissuading the Greeks from unavailing resistance to Persia: but he was in reality a very dangerous mediator; and as such the Spartans had good reason to dread him, in a second intervention of which we shall hear more hereafter. On the present occasion, the Grecian commanders were quite ignorant of the existence of any other entrance into Thessaly, besides Tempe, until their arrival in that region. Perhaps it might have been possible to defend both entrances at once, and considering the immense importance of arresting the march of the Persians at the frontiers of Hellas, the attempt would have been worth some risk. So great was the alarm, however, produced by the unexpected discovery, justifying or seeming to justify the friendly advice of Alexander, that they remained only a few days at Tempe, then at once retired back to their ships, and returned by sea to the Isthmus of Corinth—about the time when Xerxes was crossing the Hellespont.
This precipitate retreat produced consequences highly disastrous and discouraging. It appeared to leave all Hellas north of Mount Cithæron and of the Megarid territory without defence, and it served either as reason or pretext for the majority of the Grecian states, north of that boundary, to make their submission to Xerxes, which some of them had already begun to do before. When Xerxes in the course of his march reached the Thermaic Gulf, within sight of Olympus and Ossa, the heralds whom he had sent from Sardis brought him tokens of submission from a third portion of the Hellenic name—the Thessalians, Dolopes, Ænianes, Perrhæbians, Magnetes, Locrians, Dorians, Melians, Phthiotic Achæans, and Bœotians. Among the latter is included Thebes, but not Thespiæ or Platæa. The Thessalians, especially, not only submitted, but manifested active zeal and rendered much service in the cause of Xerxes, under the stimulus of the Aleuadæ, whose party now became predominant: they were probably indignant at the hasty retreat of those who had come to defend them.
Had the Greeks been able to maintain the passes of Olympus and Ossa, all this northern fraction might probably have been induced to partake in the resistance instead of becoming auxiliaries to the invader. During the six weeks or two months which elapsed between the retreat of the Greeks from Tempe and the arrival of Xerxes at Therma, no new plan of defence was yet thoroughly organised; for it was not until that arrival became known at the isthmus, that the Greek army and fleet made its forward movement to occupy Thermopylæ and Artemisium.[b]
XERXES REVIEWS HIS HOST
Xerxes having ranged and numbered his armament, was desirous to take a survey of them all. Mounted in his car, he examined each nation in its turn. To all of them he proposed certain questions, the replies to which were noted down by his secretaries. In this manner he proceeded from first to last through all the ranks, both of horse and foot. When this was done, the fleet also was pushed off from land, whilst the monarch, exchanging his chariot for a Sidonian vessel, on the deck of which he sat beneath a golden canopy, passed slowly the heads of the ships, proposing in like manner questions to each, and noting down the answers. The commanders had severally moored their vessels at about four plethra from shore, in one uniform line, with their sterns out to sea, and their crews under arms, as if prepared for battle. Xerxes viewed them, passing betwixt their prows and the shore.
