The expedition sailed from Miletus; and, in order to prevent the people of Naxos from being apprised of their danger, the report had been circulated that its destination was to be the Hellespont. Accordingly, when the fleet sailed, it turned its course to the northward, as if it were really going to the Hellespont. The plan of the commander was to stop after proceeding a short distance, and then to seize the first opportunity afforded by a wind from the north to come down suddenly upon Naxos, before the population should have time to prepare for defense. Accordingly, when they arrived opposite the island of Chios, the whole fleet came to anchor near the land. The ships were all ordered to be ready, at a moment's warning, for setting sail; and, thus situated, the commanders were waiting for the wind to change. Megabates, in going his rounds among the fleet while things were in this condition, found one vessel entirely abandoned. The captain and crew had all left it, and had gone ashore. They were not aware, probably, how urgent was the necessity that they should be every moment at their posts. The captain of this galley was a native of a small town called Cnydus, and, as it happened, was a particular friend of Aristagoras. His name was Syclax. Megabates, as the commander of the fleet, was very much incensed at finding one of his subordinate officers so derelict in duty. He sent his guards in pursuit of him; and when Syclax was brought to his ship, Megabates ordered his head to be thrust out through one of the small port-holes intended for the oars, in the side of the ship, and then bound him in that position--his head appearing thus to view, in the sight of all the fleet, while his body remained within the vessel. "I am going to keep him at his post," said Megabates, "and in such a way that every one can _see_ that he is there." Aristagoras was much distressed at seeing his friend suffering so severe and disgraceful a punishment. He went to Megabates and requested the release of the prisoner, giving, at the same time, what he considered satisfactory reasons for his having been absent from his vessel. Megabates, however, was not satisfied, and refused to set Syclax at liberty. Aristagoras then told Megabates that he mistook his position in supposing that he was master of the expedition, and could tyrannize over the men in that manner, as he pleased. "I will have you understand," said he, "that I am the commander in this campaign, and that Artaphernes, in making you the sailing-master of the fleet, had no intention that you should set up your authority over mine." So saying, he went away in a rage, and released Syclax from his durance with his own hands.
