The various cities were mutually jealous and hostile, and it took a great common danger to bring them even into a semblance of coöperation. Even during this desperate crisis the cities of western Greece, counting themselves reasonably safe from invasion, declined to send a ship or a man for the common cause.

ROUTE OF XERXES' FLEET TO BATTLE OF SALAMIS

The Persian army advanced without opposition as far as the pass of Thermopylæ, which guarded the only road into the rest of Greece. Twelve days after the army had started on its march the great fleet crossed the Ægean to establish contact with the army and bring supplies. The army was checked by the valor of Leonidas, and the Persian fleet was intercepted by a Greek fleet which stood guard over the channel leading to the Gulf of Lamia, thus protecting the sea flank of Leonidas. The Persian fleet, after crossing the open sea safely, made its base at Sepias preparatory to the attack on the Greek fleet. The latter numbered only about 380 vessels to some 1200 of their enemy and the prospects for the Persian cause looked bright indeed. But as the very number of the Persian ships made it impossible to beach all of them for the night a large proportion of them were anchored, lying in eight lines, prows toward the sea. At dawn a northeast gale fell upon them, and, according to the Greek accounts, wrecked 400 triremes, together with an uncounted number of transports. Meanwhile the Greek ships had taken refuge under the lee of the island of Eubœa, and the news of the Persian disaster was signaled to them by the watchers on the heights.

SCENE OF PRELIMINARY NAVAL OPERATIONS, CAMPAIGN OF SALAMIS

As soon as the weather moderated the Greeks returned to their position in the straits near Artemisium, and during the next three days the two fleets fought stubbornly but without advantage to either side. During the second day a southerly gale caught a flying squadron of some 200 triremes, that had been dispatched round the island of Eubœa to catch the Greeks in the rear, and not one of the Persian ships survived. The Greek rear guard squadron of fifty brought the welcome news to the main fleet and served as a much needed reënforcement. Although the Persian armada had lost about half its force in three days by storms, the odds were still so heavily against the Greeks that they found themselves in constant peril of having their flanks turned in this open sea fighting.

On the afternoon of the third day the pass of Thermopyæ was forced, thanks to the treachery of a Greek and the contemptible policy of the Spartan government which steadily refused the plea of Leonidas for reënforcements. With Thermopyæ taken there was no further reason for the Greek fleet to try to hold the straits north of Eubœa, and during the night it retired unobserved. The following day the Persian fleet advanced and brought to the army the supplies which it sorely needed.

With the fall of Thermopyæ and the contact established between his army and his fleet, Xerxes found his route open for the invasion of Attica. Since there was no possibility of opposing him on land, the population of the province was removed and Athens left to its fate. Themistocles, who was in command of the Athenian division of the Greek fleet, now urged the assembling of the fleet at Salamis, partly to cover the withdrawal of the Athenians and partly to assist in the defense of the Isthmus of Corinth, which was to be the next stand of the Greeks. The advice was adopted and the fleet assembled off the town of Salamis. Athenian refugees had crowded into the town and from the heights above they watched the smoke of their burning city. Their own future and the future of Athenian civilization hung on the long lines of triremes drawn up on the shore.

A glance at the map of the region of Salamis shows the advantages offered by the position for the defensive. The fighting off Artemisium had shown the peril of attacking a greatly superior force in the open because of the danger of being outflanked. In the narrow straits between Salamis and the mainland the Greek line of battle would rest its flanks on the opposite shores. But it is one thing to choose a position and another to get the enemy to accept battle in that position. If the Persians ignored the Greek fleet and moved to the Isthmus, the Greeks would be caught in an awkward predicament. To regain touch with the Greek army, the fleet would be then compelled to come out of the straits and fight at a disadvantage in the open. There was only one chance of defeating the Persian fleet and that was to make it fight in the narrow waters of the strait where numbers would not count so heavily. Everything depended on bringing this to pass.

Nor could the Greeks wait indefinitely for the Persians. Already the incorrigible jealousies of rival cities had almost reached the point of disintegrating the fleet. Although the commander in chief was the Spartan general Eurybiades, the whole Spartan contingent was on the point of deserting in a body to its own coasts. The situation was saved by Themistocles. Having wrung from his allies a reluctant consent to stop at Salamis temporarily to cover the withdrawal of the Athenian populace, the story is that he secretly dispatched a messenger to Xerxes to say that if he would attack at once he could crush the entire naval forces of the Greeks at a blow, but if he delayed the Greeks would scatter. Acting on this advice, Xerxes landed troops on the island of Psyttaleia, dispatched a squadron to block the western outlet of Salamis Straits, and proceeded to move the main body of his fleet to attack the Greeks by way of the eastern channel. The preparations were made during the night and were not completed till dawn of the day of battle, September 20, 480 B.C.

The debates in the allied fleet came to an end with the appearance of the Persians. The shrewd plan of Themistocles had succeeded. The Greeks would have to fight with their backs to the wall, but they would fight with better chance of success than under any other circumstances.

The Greek force consisted of about 380 vessels. Of these, Athens contributed 180, Sparta and the rest of the Peloponnesus were represented by 89 and the remainder were made up of squadrons from the island states. Some of these island contingents contained a type of ship different from the triremes, the penteconter. This was a galley with only one bank of oars, but these were long sweeps, each manned by five oarsmen. The penteconter was an early prototype of the galley of the Christian era.

The Persians had been reduced by this time to about 600 ships, although there had been numerous reënforcements since the disaster at Cape Sepias.
