The Battle of Dumlupınar was the concluding engagement of the Greco-Turkish War (1919-1922) and a decisive encounter within the broader context of the Turkish War of Independence. Following the invasion of Western Anatolia by Greek forces in 1919, the Turkish National Movement, under the leadership of Mustafa Kemal Atatürk, rallied to reclaim their homeland. The Turks aimed to resist the Greek advance and restore sovereignty over their territories. The battle unfolded from August 26 to August 30, 1922, near the town of Dumlupınar, located in present-day Kütahya Province, Turkey.In the lead-up to the battle, Mustafa Kemal organized a strategic counter-offensive titled the Great Offensive. The Turkish forces, numbering approximately 100,000 troops, launched a coordinated assault against a significantly larger but demoralized Greek army, estimated at around 80,000 men. The Greeks, hindered by supply issues and low morale, struggled to maintain their positions. The battle commenced with a diversionary attack in the west, drawing Greek forces away while the main assault hit hard in the center. Turkish troops swiftly broke through Greek lines, employing tactical maneuvers and heavy artillery to gain the upper hand.The culmination of the battle saw the Greek army in retreat, leading to a significant influx of Turkish forces into western Anatolia. The battle resulted in tens of thousands of Greek casualties, both killed and wounded, along with the widespread capture of Greek soldiers. By the end of August 1922, the Turkish victory at Dumlupınar effectively altered the regional balance of power, laying the groundwork for the establishment of the Republic of Turkey in 1923.
