However, according to Herodotus, Histiaeus was unhappy having to stay in Susa, and made plans to return to his position as King of Miletus by instigating a
revolt in Ionia. In 499 BC, he shaved the head of his most trusted slave,
tattooed a message on his head, and then waited for his hair to grow back. The slave was then sent to Aristagoras, who was instructed to shave the slave's head again and read the message, which told him to revolt against the Persians. Aristagoras, who was disliked by his own subjects after an expedition to
Naxos ended in failure, followed Histiaeus' command, and with help from the
Athenians and
Eretrians, attacked and burned Sardis. When Darius learned of the revolt, he sent for Histiaeus, who pretended to have no knowledge of its origins, but asked to be sent back to Miletus to put down the revolt. Herodotus writes that Darius permitted him to leave. On his way back, Histiaeus went to Sardis, where the
satrap Artaphernes suspected Histiaeus' role in the revolt, forcing Histiaeus to flee to
Chios. Histiaeus tried unsuccessfully to build a fleet while on Chios. He then returned to Miletus with the aim of becoming tyrant once more. However, the Miletians did not want a return to tyranny and exiled him to
Lesbos. There, he gathered some ships and, according to Herodotus, began committing acts of
piracy in the
Black Sea and the
Aegean Sea from a base in
Byzantium. Meanwhile, the Persians defeated the leaders of the Ionian revolt at the
Battle of Lade in 494 BC. When Histiaeus learned of this he left Byzantium, and his troops attacked Chios, blockaded
Thasos and then attempted to land on the mainland to attack the Persians. After joining a Greek force in battle against the Persians, he was captured by the Persian general,
Harpagus in 493 BC. The satrap
Artaphernes did not want to send him back to Susa, where he suspected that Darius would pardon him, so he executed him by impaling, and sent his head to Darius. According to Herodotus, Darius still did not believe Histiaeus was a traitor and gave his head an honourable burial. ==See also==
