Battle of Abu Tellul

The Battle of Abu Tellul (called the Affair of Abu Tellul by the British Battles Nomenclature Committee) 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 EF the first in March and second in April the defence of the valley became the responsibility of the Desert Mounted Corps.

A German and Ottoman force attacked the Australian Light Horse units defending the heights at Mussallabeh and Abu Tellul on the edge of the Judean Hills, while a German force attacked those defending the Wadi Mellaha midway between Abu Tellul and the Jordan River. As these attacks were taking place on the western bank of the river, on the eastern side the Ottoman Caucasus Cavalry Brigade deployed two regiments, to attack the bridgeheads at the fords of El Hinu and Makhadet Hijla. However, the Ottoman formation was overwhelmed by a combined force of British and Indian troops before it could launch its attack. These were the last attacks against the British forces in this campaign.

Military situation
Abu Tellul was a strategically important ridge located near the west bank of the Jordan river which, together with another ridge to the north called Mussallabeh, formed a salient in the British defensive line in the Jordan valley. A number of defensive posts were constructed by the Australian and New Zealand garrison which were often between 400 yards (370 m) and 1,000 yards (910 m) apart, consisting of either dug or built up stone sangars, while the ravines in between were covered with barbed wire. The British artillery batterieswere concealed close behind the front line just south of the ridge.

El Mussallabeh had been attacked on 11 April, between the first and second Transjordan raids. The attack had been launched by a composite force of four Ottoman infantry battalions and several batteries. Subsequently, defensive work was carried out. From early May, when the withdrawal of the forces involved in the second Transjordan attack was complete, the occupation of the Jordan Valley by the Egyptian Expeditionary Force was unchallenged, except for the attacks on 14 July and shelling by long-range Ottoman and German artillery.

The Ottoman and German attack occurred on the front line protecting the garrison in the valley; the main focus being a salient in the wilderness to the north north west of the Wadi el Auja on the western side of the Jordan River. They sought to cut off the British force in the Jordan Valley from the infantry holding the front line in the Judean Hills by creating a wedge between the infantry and the mounted force in the valley. Such an action would, if successful, have destabilised British control of the Jordan and Dead Sea area, effectively ending the threat of a third Transjordan attack by pushing Lieutenant General Harry Chauvel's forces back out of the Jordan Valley. If the attack succeeded, the front line stretching from the Mediterranean Sea would have been considerably shortened and potentially destabilised. The Ottoman Eighth Army defending the coastal sector, the Seventh Armydefending the Judean Hills and the Fourth Army defending the east would have been able to strengthen their considerably shorter line to threaten General Edmund Allenby's right flank making the attacks in September at Megiddo very difficult, if not virtually impossible.
