Greece dispatched the Army of Epirus and the Army of Thessaly to its frontiers in Epirus and Thessaly respectively. The latter numbered 100,000 men, and was divided into seven divisions: namely the 1st, the 2nd, the 3rd, the 4th, the 5th, the 6th and the 7th Infantry Divisions, as well as a cavalry brigade and four independent Evzones battalions. The Army of Thessaly was commanded by Crown Prince Constantine. Facing the Greeks in Thessaly was the Ottoman VIII Corps under General Hasan Tahsin Pasha which included three divisions: the regular ("nizamiye") 22nd Division and the reserve ("redif") Nasliç and Aydın Divisions which, combined with the Ottoman garrisons in western Macedonia, totaled 35,000–40,000 men.
