The Battle of Abu Tellul (called the Affair of Abu Tellul by the British Battles Nomenclature Committee[6]) was fought on 14 July 1918 during the Sinai and Palestine Campaign of World War I after German and Ottoman Empire forces attacked the British Empire garrison in the Jordan Valley. The valley had been occupied by the Egyptian Expeditionary Force (EEF) from February 1918 when Jericho was captured. Following two raids east of the River Jordan by the EEF the first in March and second in April the defence of the valley became the responsibility of the Desert Mounted Corps.
