Alcimachus was the father of the traitor Euphorbus: Hdt. 6.101, Paus. 7.10.2
... The Eretrians had no intention of coming out and fighting; all their care was to guard their walls if they could, since it was the prevailing counsel not to leave the city. The walls were strongly attacked, and for six days many fell on both sides; but on the seventh two Eretrians of repute, Euphorbus son of Alcimachus and Philagrus son of Cineas, betrayed the city to the Persians.  They entered the city and plundered and burnt the temples, in revenge for the temples that were burnt at Sardis; moreover, they enslaved the townspeople, according to Darius' command.
After reducing Ionia the Persians enslaved Eretria also, the most famous citizens turning traitors, Philagrus, the son of Cyneas, and Euphorbus, the son of Alcimachus.
