Following the First Transjordan and the Second Transjordan attacks in March–April and April–May 1918, by the Egyptian Expeditionary Force (EEF), which had been responsible for the Sinai and Palestine Campaign since March 1916, its commander General Edmund Allenby ordered the occupation of the Jordan Valley.
He also ordered the front line be extended across the Judean Hills to the Mediterranean.
Most of the British infantry and Yeomanry cavalry regiments were redeployed to the Western Front to counter Ludendorff's Spring Offensive and were replaced by British India Army infantry and cavalry.
As part of re-organisation and training, these newly arrived soldiers carried out a series of attacks on sections of the Ottoman front line during the summer months.
These attacks were aimed at pushing the front line to more advantageous positions in preparation for a major attack, and to acclimatise the newly arrived infantry.
It was not until the middle of September that the consolidated force was ready for large-scale operations.

On 19 September, the XXI Corps commanded by Lieutenant General Edward Bulfin had, with the support of a creeping barrage, broken through the Ottoman front line to begin the Battle of Sharon.
In the afternoon the XX Corps commanded by Lieutenant General Philip Chetwode was then ordered to begin the Battle of Nablus, supported by an artillery barrage.
These infantry attacks by both the XX and XXI Corps, known as the Battle of Megiddo, continued until midday on 21 September, when a successful flanking attack by the XXI Corps, combined with the XX Corps assault, forced the Seventh and Eighth Armies to disengage.
The Seventh Army retreated from the Nablus area towards the Jordan River, crossing at the Jisr ed Damieh bridge before the rearguard at Nablus was captured.
The Desert Mounted Corps commanded by Lieutenant General Harry Chauvel advanced through the gap created by the XXI Corps infantry during the morning of 19 September to continue the Battle of Megiddo, almost encircling the Ottoman forces fighting in the Judean Hills, capturing Nazareth, Haifa, Afulah and Beisan, Jenin and Samakh before advancing to Tiberias.
During this time, Chaytor's Force commanded by Major General Edward Chaytor captured part of the retreating Ottoman and German column at the capture of Jisr ed Damieh bridge to cut off this line of retreat across the Jordan River.
To the east of the river, as the Fourth Army began its retreat, Chaytor's Force advanced to capture Es Salt on 23 September.
Amman was captured on 25 September during the Second Battle of Amman where a strong Fourth Army rearguard was defeated on 25 September.

Tiberias is one of the Four Holy Cities of the Jews; the others being Jerusalem, Hebron and Safed.
It is situated on the western shore of the Sea of Galilee, and is separated by a narrow plain from the Nazareth hills to the west.
Tiberias was the seat of a Kaimmakam (district) within the Ottoman sanjak (prefecture) of Acre and had a population of about 8,600, including 7,000 Jews, many of whom were German-speaking immigrants from Poland.
There were also 1,400 Muslims and 200 Christians living in the town, which was surrounded by ancient walls.
At this time Tiberias was connected to southern Palestine via Nazareth by metalled roads and by an alternative route to Afulah via Beisan, which was also suitable for wheeled vehicles.
The main road north from Tiberias to Damascus crossed the Jordan River at the bridge at Jisr Benat Yakub.

During the unsuccessful attack of the 5th Cavalry Division on Nazareth in the early morning of 20 September, the commander of the Yildirim Army Group commanding three Ottoman armies, Generalleutnant (comparable to a British Major General) Otto Liman von Sanders escaped to Damascus, travelling via Tiberias, Samakh and Deraa.
He alerted the garrisons he passed to the advance of the EEF and ordered the establishment of a rearguard line.
The line was to run from Deraa down the Yarmuk River Valley, across the Jordan River and west to Samakh, around the shore of the Sea of Galilee to Tiberias a
