The first landing took place on 17 November 1918 at Mersin with roughly 15,000 men, mainly volunteers from the French Armenian Legion, accompanied by 150 French officers. The first goals of that expeditionary force were to occupy ports and dismantle the Ottoman administration. On 19 November, Tarsus was occupied in order to secure the surroundings and prepare for the establishment of headquarters in Adana. After the occupation of Cilicia proper at the end of 1918, French troops occupied the Ottoman provinces of Antep, Marash and Urfa in southern Anatolia at the end of 1919, taking them over from British troops as agreed. In the regions they occupied, the French encountered immediate resistance from the Turkish, especially because they had associated themselves with Armenian objectives. The French soldiers were foreign to the region and were using Armenian militia to acquire their intelligence. Turkish nationals had been in cooperation with Arab tribes in this area. Compared to the Greek threat, the French seemed less dangerous to Mustafa Kemal Pasha, who suggested that, if the Greek threat could be overcome, the French would not hold its territories in Turkey, especially as they mainly wanted to settle in Syria.
