Xenophon's Anabasis (Cambridge, Trinity College, MS R.9.29)

...to the gates of Cilicia and Syria. There were two walls, and the one on the inside, before Cilicia, Syennesis held, with a guard of Cilicians; the outer one, toward Syria, was said to be guarded by the King’s garrison. Through the middle of these flows a river, named Carsus, a plethron in width. The entire space between the walls was three stadia, and it was not possible to pass by force; for the passage was narrow, and the walls reached down to the sea, and above were sheer, impassable rocks; and gates had been set upon both walls. Because of this narrow passage, Cyrus sent for the ships, so that he might land hoplites, inside and outside the gates, and having forced the enemy, they might pass through, if they were guarding at the Syrian gates, which Cyrus thought Abrocomas would do, as he had a large army. But Abrocomas did not do this; rather, when he heard that Cyrus was in Cilicia, he turned back from Phoenicia and marched away toward the King, having, as it was said, three hundred thousand troops. From there he marches through Syria one stage, five parasangs, to Myriandrus, a city inhabited by Phoenicians on the sea; the place was a trading post. And many merchant ships were anchored there. There they remained for seven days, and Xenias the Arcadian general and Pasion the Megarian, having boarded a ship and put on board their most valuable possessions, sailed away. Most people thought they did this out of jealousy because Cyrus allowed Clearchus to keep their soldiers who had gone over to him, intending to return to Greece and not against the King. Since they were missing, the story went around that Cyrus was pursuing them with triremes. Some prayed that they would be captured as traitors.
