During the early stages of the war while the Balkan allies were victorious, the Hellenic Army liberated Thessaloniki and continued to advance west in Macedonia to Kastoria and then Korytsa.

The Epirus front was also active and the Ottoman forces under Djavid Pasha placed 24,000 Ottoman troops in Korytsa in order to protect north of Ioannina, the urban center of the Epirus region. On December 20, three days after peace negotiations started,^[57] the Greek forces pushed the Ottomans out of Korytsa.^[58]

This would give the Greek forces a significant advantage in controlling Ioannina and the entire area in March 1913 at the Battle of Bizani.
