Paragraph 15 15. On the third day the commanders of the Barbarians, being exceedingly indignant that so small a number of ships should thus do them damage, and fearing what Xerxes might do, did not wait this time for the Hellenes to begin the fight, but passed the word of command and put out their ships to sea about the middle of the day. Now it so happened that these battles at sea and the battles on land at Thermopylai took place on the same days; and for those who fought by sea the whole aim of the fighting was concerned with the channel of Euripos, just as the aim of Leonidas and of his band was to guard the pass: the Hellenes accordingly exhorted one another not to let the Barbarians go by into Hellas; while these cheered one another on to destroy the fleet of the Hellenes and to get possession of the straits.
Paragraph 16 16. Now while the forces of Xerxes were sailing in order towards them, the Hellenes kept quiet at Artemision; and the Barbarians, having made a crescent of their ships that they might enclose them, were endeavouring to surround them. Then the Hellenes put out to sea and engaged with them; and in this battle the two sides were nearly equal to one another; for the fleet of Xerxes by reason of its great size and numbers suffered damage from itself, since the ships were thrown into confusion and ran into one another: nevertheless it stood out and did not give way, for they disdained to be turned to flight by so few ships. Many ships therefore of the Hellenes were destroyed and many men perished, but many more ships and men of the Barbarians. Thus contending they parted and went each to their own place.
Paragraph 17 17. In this sea-fight the Egyptians did best of the men who fought for Xerxes; and these, besides other great deeds which they displayed, captured five ships of the Hellenes together with their crews: while of the Hellenes those who did best on this day were the Athenians, and of the Athenians Cleinias the son of Alkibiades, who was serving with two hundred man and a ship of his own, furnishing the expense at his own proper cost.
