Answer
The Battle of Dumlupınar, a crucial turning point in the Greco-Turkish War of 1919-1922, took place in August 1922 and witnessed the resignation of Turkish Prime Minister Fevzi Çakmak to personally lead the Turkish forces. Çakmak's strategic leadership proved instrumental in securing a decisive victory against the Greek army, ultimately paving the way for the Turkish War of Independence and the establishment of the modern Republic of Turkey.
