Herodotus recounts that Megabates made inspections of the ships (probably whilst beached for the night), and came across one ship from Myndus which had not posted any sentries. Megabates ordered his guard to find the captain of the ship, Scylax, and then had the captain thrust into one of the ship's oar holes with his head outside and his body inside the ship. News reached Aristagoras of the treatment of his friend and he went to Megabates and asked him to reconsider his decision. When Megabates refused to grant Aristagoras's wishes, Aristagoras simply cut the captain loose himself. Predictably, Megabates was furious with Aristagoras, who in turn retorted "But you, what have you to do with these matters? Did not Artaphernes send you to obey me and to sail wherever I bid you? Why are you so meddlesome?". According to Herodotus, Megabates was so enraged by this that he sent messengers to the Naxians to warn them of the approach of the Persian force.
