Battle of Kanlı Geçit

French interest in the region was sparked by the Sykes-Picot Agreement, signed amidst World War I.

By November 1, 1920 various forces were scattered in national detachments within in the town of Osmaniye, but in the morning hours a large part of the French force advanced to Mamure railway station without suffering any resistance from the 1000 Kuva-yi Milliye militias. French forces advancing in the direction of "the bell" were met with resistance but continued to advance towards Kanlı Geçit also referred to as "the Bloody Gateway." By noon, all French forces had reached the Blood Alley-Mamure railway line. Turkish forces from Osmaniye were able to retreat to Yarpuz, 20 km away. Turkish Forces from Ceyhan retreated to the northern bank of the Ceyhan River with a portion of the platoon beginning to move towards Kadirli.

French forces north of the Ceyhan River and east of the starting offensive, were placed under intense fire by Turkish forces. This fire was continued against French forces east of the Ceyhan River resulting in heavy casualties. As a result French forces there were repelled.

Attacks from both sides ceased during the consolidation of Turkish and French forces at "Bloody Gateway." However, on the morning of November 8, 1920 the French began to fire on Turkish forces. In addition to ground fire, Turkish forces were also assaulted by French aircraft passing overhead. During this early morning attack, the French captured the high positions of the Turkish forces, but by evening these positions were taken back by the Turkish. During this attack the French managed to occupy a hill, where they then spent the night.
