Иоанн Дука
In the aftermath of this success, John Palaiologos joined by the forces of John Doukas, marched south into Thessaly, seizing and fortifying its fortresses, until he reached the town of Neopatras, where he made his camp for a time. He then continued on into Boeotia; the territory of the Duchy of Athens, where he took and plundered Levadeia and Thebes. At this point, however, John Doukas defected back to his father, upsetting the balance of power and John himself was soon after recalled to Lampsacus. Thus, his conquest of Greece remained incomplete and was soon reversed by the recovery of Epirus' fortunes.
