The Great Offensive-one of the greatest military victories in history-was launched by the Turkish Armed Forces on Aug. 26, 1922, under the leadership of Mustafa Kemal Ataturk, the founder of modern Türkiye, and ended on Sept. 18 that same year.
From Aug. 26 to Aug. 30 of 1922, Turkish forces fought the Battle of Dumlupinar (considered part of the Greco-Turkish War) in Türkiye's western Kutahya province, where Greek forces were decisively defeated.
