Historical Map of Europe & the Mediterranean
With the collapse of the Ottoman Empire, Greece moved troops into western Turkey to protect the sizeable local Greek population and assert its historical claim over the region. Initially the war favored Greece, but by late 1921 the Turks were gaining the upper hand.

Battle of Sakarya
The invading Greek army advanced on the Turkish Nationalist lines on the Sakarya River, 80km from the Nationalist capital of Ankara. By September 2, the Greeks had captured Mount Chal and in the ensuing 10 days, some units come within 50km of Ankara. However, the Greeks were overextended, and a Turkish counterattack on September 8 forced them to abandon the offensive and withdraw toward Eskişehir and Kara Hisar.
