History of the Peloponnesian War

As soon as the Athenians heard the news, they sailed with sixty ships against Samos. Sixteen of these went to Caria to look out for the Phoenician fleet, and to Chios and Lesbos carrying round orders for reinforcements, and so never engaged; but forty-four ships under the command of Pericles with nine colleagues gave battle, off the island of Tragia, to seventy Samian vessels, of which twenty were transports, as they were sailing from Miletus. Victory remained with the Athenians.

Reinforced afterwards by forty ships from Athens, and twenty-five Chian and Lesbian vessels, the Athenians landed, and having the superiority by land invested the city with three walls; it was also invested from the sea.

Meanwhile Pericles took sixty ships from the blockading squadron, and departed in haste for Caunus and Caria, intelligence having been brought in of the approach of the Phoenician fleet to the aid of the Samians; indeed Stesagoras and others had left the island with five ships to bring them.
