During this period, the
Dolonci (a tribe from the Thracian Chersonese) suffered several military defeats against their rivals, the
Apsinthians. They travelled to the
Oracle of Delphi for advice, and were told to return to Thrace with a
Greek colonist as their commander. The Dolonci asked Miltiades to take on this role, due to the hospitality he showed them on their return trip through Athens. Miltiades arrived in the Thracian Chersonese with a group of Athenian settlers, probably between 556 BC and 550 BC, Miltiades was also credited with the founding of several other Thracian cities, including
Pactye,
Agora, and
Crithote. Miltiades' most famous construction was the
Long Wall stretching from Cardia to Pactye. This wall was completed relatively early in Miltiades' reign, most likely prior to 546 BC, and was designed to keep the Apsinthians out of the peninsula. During his reign, Miltiades also went to war against the city of
Lampsacus. This war was largely unsuccessful, and Miltiades was briefly taken captive in a Lampsacene ambush. However,
Croesus of Lydia interceded on behalf of Miltiades, compelling the Lampsacenes to release him unharmed. In the Thracian Chersonese, an annual contest in horse-racing and gymnastics was then inaugurated in Miltiades' memory; == The three-Miltiades theory ==
