P: In 1344, Momchil, the independent Bulgarian ruler of the Rhodope and Aegean regions, whose army grew to 2,000 men, took an important role in the Byzantine civil war. While at first he supported John Kantakouzenos, from the spring of 1344 Momchil reneged, provoked by the aggression of the Ottoman allies. In June he defeated the Ottoman fleet near the Portogalos bay. According to sources, at night the Bulgarian ruler sent boats to burn the anchored Ottoman ships and soon after he defeated the army of Kantakouzenos at Mosynopolis. Probably the first local ruler to become aware of the impending Ottoman threat, Momchil unsuccessfully pleaded with the emperors of Bulgaria and Byzantium for help. Even though his troops continued the resistance in the Eastern Rhodopes, in May 1345 the Turks led by Umur Beg marched from Asia Minor and devastated Bulgarian territories driving away people and livestock. Soon after, on 7 July 1345, Ottoman forces under Umur Beg defeated Momchil's army in the battle of Peritor near his capital Xanthi. Sources attest that the independent ruler perished in the battle without leaving asuccessor, and with little political will or leadership left to counter the Ottoman invasion.
