The Battle of Gallipoli was fought in 1312, between the Byzantine Empire, Serbian Kingdom and Republic of Genoa against Turcopoles led by Halil Pasha. For two years, Thrace was occupied by Halil Pasha. Meanwhile, the local inhabitants could not cultivate their lands, since the Turcopoles were looting and pillaging the countryside. The Byzantine emperor, Michael IX, raised an army and confined the Turcopoles to the Gallipoli peninsula. He was aided by troops sent by Serbian King Stefan Uroš II Milutin numbering some 2000 Cumans or Serbs, while the Genoese prevented the Turcopoles from escaping by sea. Halil himself and the Turcopoles were massacred. Few of the Turcopoles returned to Byzantine service.
