However, Histiaeus argued that they should stay, as they owed their positions as tyrants to Darius and would surely be overthrown if he were killed.
Herodotus writes that while the Scythians were away, the Persians returned to the Danube and Histiaeus organised the ships to successfully ferry them across the river.
During the expedition, Histiaeus' troops had started building a settlement at Myrcinus (site of the later Amphipolis) on the Strymon River.
Nevertheless, Darius considered Histiaeus to be loyal, and asked him to come back to Susa with him as a friend and advisor.
[3] 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.
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.
