Political map of South & Southwest Asia 05 October 1918 (Capture of Damascus): The long stand-off between the Allies and the Ottomans in Palestine (Sinai and Palestine Campaign) was finally ended in September 1918 with the Battle of Megiddo (Battle of Megiddo (1918)). Advancing across the front, the British and Arab forces decisively defeated the Ottoman army, entering Damascus on 1 October (Capture of Damascus (1918)). However these Anglo-Arab successes worried the French, who had been promised Syria by the British in the Sykes-Picot Agreement of 1916.
