From the first, even earlier than the time when the embassy went to Sicily to solicit alliance, there had been a talk of intrusting the Athenians with the command at sea; but the allies were averse to the plan, wherefore the Athenians did not press it; for there was nothing they had so much at heart as the salvation of Greece, and they knew that, if they quarrelled among themselves about the command, Greece would be brought to ruin. Herein they judged rightly; for internal strife is a thing as much worse than war carried on by a united people, as war itself is worse than peace. The Athenians therefore, being so persuaded, did not push their claims, but waived them, so long as they were in such great need of aid from the other Greeks. And they afterwards showed their motive; for at the time when the Persians had been driven from Greece, and were now threatened by the Greeks in their own country, they took occasion of the insolence of Pausanias to deprive the Lacedaemonians of their leadership. This, however, happened afterwards.

At the present time the Greeks, on their arrival at Artemisium, when they saw the number of the ships which lay at anchor near Aphetae, and the abundance of troops everywhere, feeling disappointed that matters had gone with the barbarians so far otherwise than they had expected, and full of alarm at what they saw, began to speak of drawing back from Artemisium towards the inner parts of their country. So when the Euboeans heard what was in debate, they went to Eurybiades, and besought him to wait a few days, while they removed their children and their slaves to a place of safety. But, as they found that they prevailed nothing, they left him and went to Themistocles, the Athenian commander, to whom they gave a bribe of thirty talents, on his promise that the fleet should remain and risk a battle in defence of Euboea.

And Themistocles succeeded in detaining the fleet in the way which I will now relate. He made over to Eurybiades five talents out of the thirty paid him, which he gave as if they came from himself; and having in this way gained over the admiral, he addressed himself to Adeimantus, the son of Ocytus, the Corinthian leader, who was the only remonstrant now, and who still threatened to sail away from Artemisium and not wait for the other captains. Addressing himself to this man, Themistocles said with an oath- "Thou forsake us? By no means! I will pay thee better for remaining than the Mede would for leaving thy friends"- and straightway he sent on board the ship of Adeimantus a present of three talents of silver. So these two captains were won by gifts, and came over to the views of Themistocles, who was thereby enabled to gratify the wishes of the Euboeans. He likewise made his own gain on the occasion; for he kept the rest of the money, and no one knew of it. The commanders who took the gifts thought that the sums were furnished by Athens, and had been sent to be used in this way.

Thus it came to pass that the Greeks stayed at Euboea and there gave battle to the enemy.

Now the battle was on this wise. The barbarians reached Aphetae early in the afternoon, and then saw (as they had previously heard reported) that a fleet of Greek ships, weak in number, lay at Artemisium. At once they were eager to engage, fearing that the Greeks would fly, and hoping to capture them before they should get away. They did not however think it wise to make straight for the Greek station, lest the enemy should see them as they bore down, and betake themselves to flight immediately; in which case night might close in before they came up with the fugitives, and so they might get clean off and make their escape from them; whereas the Persians were minded not to let a single soul slip through their hands.

They therefore contrived a plan, which was the following:- They detached two hundred of their ships from the rest, and- to prevent the enemy from seeing them start- sent them round outside the island of Sciathos, to make the circuit of Euboea by Caphareus and Geraestus, and so to reach the Euripus. By this plan they thought to enclose the Greeks on every side; for the ships detached would block up the only way by which they could retreat, while the others would press upon them in front. With these designs therefore they dispatched the two hundred ships, while they themselves waited- since they did not mean to attack the Greeks upon that day, or until they knew, by signal, of the arrival of the detachment which had been ordered to sail round Euboea. Meanwhile they made a muster of the other ships at Aphetae.

Now the Persians had with them a man named Scyllias, a native of Scione, who was the most expert diver of his day. At the time of the shipwreck off Mount Pelion he had recovered for the Persians a great part of what they lost; and at the same time he had taken care to obtain for himself a good share of the treasure. He had for some time been wishing to go over to the Greeks; but no good opportunity had offered till now, when the Persians were making the muster of their ships. In what way he contrived to reach the Greeks I am not able to say for certain: I marvel much if the tale that is commonly told be true. 'Tis said he dived into the sea at Aphetae, and did not once come to the surface till he reached Artemisium, a distance of nearly eighty furlongs. Now many things are related of this man which are plainly false; but some of the stories seem to be true. My own opinion is that on this occasion he made the passage to Artemisium in a boat.

However this might be, Scyllias no sooner reached Artemisium than he gave the Greek captains a full account of the damage done by the storm, and likewise told them of the ships sent to make the circuit of Euboea.

So the Greeks on receiving these tidings held a council, whereat, after much debate, it was resolved that they should stay quiet for the present where they were, and remain at their moorings, but that after midnight they should put out to sea, and encounter the ships which were on their way round the island. Later in the day, when they found that no one meddled with them, they formed a new plan, which was to wait till near evening, and then sail out against the main body of the barbarians, for the purpose of trying their mode of fight and skill in manoeuvring.

When the Persian commanders and crews saw the Greeks thus boldly sailing towards them with their few ships, they thought them possessed with madness, and went out to meet them, expecting (as indeed seemed likely enough) that they would take all their vessels with the greatest ease. The Greek ships were so few, and their own so far outnumbered them, and sailed so much better, that they resolved, seeing their advantage, to encompass their foe on every side. And now such of the Ionians as wished well to the Grecian cause and served in the Persian fleet unwillingly, seeing their countrymen surrounded, were sorely distressed; for they felt sure that not one of them would ever make his escape, so poor an opinion had they of the strength of the Greeks. On the other hand, such as saw with pleasure the attack on Greece, now vied eagerly with each other which should be the first to make prize of an Athenian ship, and thereby to secure himself a rich reward from the king. For through both the hosts none were so much accounted of as the Athenians.
