Histories

The Athenians came with their twenty ships as well as five triremes of the Eretrians who came to the war to please not the Athenians but the Milesians themselves, thereby repaying their debt (for the Milesians had once been the allies of the Eretrians in the war against +Chalcis [23.6083,38.4667] (Perseus) Chalcis, when the Samians came to aid the Chalcidians against the Eretrians and Milesians). When these, then, and the rest of the allies had arrived, Aristagoras planned a march against Sardis [28.0167,38.475] (Perseus) Sardis.

He himself did not go with the army but remained at Miletus [27.3,37.5] (Perseus) Miletus, and appointed others to be generals of the Milesians, namely his own brother Charopinus and another citizen named Hermophantus.
