Persians lost a greater number of ships than did the Greeks, yet the fleet under Eurybiades was so heavily damaged that even Themistocles saw that safety lay in retreat. At the same time tidings reached him of the defeat of Thermopylae, and he knew that Xerxes would soon be marching to the south. The fleet must hasten home to protect her own coasts.
So the Greek fleet set sail down the long Euboean strait and did not stop until it reached the island of Salamis. But as they sailed, Themistocles bade the captains of the Athenian fleets send some of their ships to the rocks where the Persians would search for water.
On these rocks Themistocles ordered to be cut in large letters these words, 'Ye do wrong, O Ionians, by going against your fathers and bringing Hellas into slavery. If ye can, take our side; if ye cannot, then fight for neither. But if this also is impossible, at least in the battle be slack and lazy, remembering that ye are sprung from us and that we are fighting in a quarrel which ye began.'
By these words Themistocles hoped to win the Ionians to his side; or, if that might not be, he hoped at least to make Xerxes so suspicious of them that he would be afraid to let them take part in the battles which had yet to be fought.
