He wanted therefore by provoking the Persians to weaken +Nisos Samos [26.8,37.75] (island), Samos, Aegean Islands, Greece, Europe Samos as much as he could before surrendering it, for he was well aware that if the Persians were hurt they would be furiously angry with the Samians. Besides, he knew that he could get himself safely off the island whenever he liked, having built a secret passage leading from the acropolis to the sea.
Maeandrius then set sail from +Nisos Samos [26.8,37.75] (island), Samos, Aegean Islands, Greece, Europe Samos; but Charilaus armed all the guards, opened the acropolis' gates, and attacked the Persians. These supposed that a full agreement had been made, and were taken unawares; the guard fell upon them and killed the Persians of highest rank, those who were carried in litters.
They were engaged in this when the rest of the Persian force came up in reinforcement, and, hard-pressed, the guards retreated into the acropolis.
The Persian captain Otanes, seeing how big a loss the Persians had suffered, deliberately forgot the command given him at his departure by Darius not to kill or enslave any Samian but to deliver the island intact to Syloson; and he commanded his army to kill everyone they took, men and boys alike.
Then, while some of the Persians laid siege to the acropolis, the rest killed everyone they met, inside the temples and outside the temples alike.
