Cause

Following victories at the Battle of Mughar Ridge, the Battle of Jerusalem, and the Capture of Jericho, the Egyptian Expeditionary Force consolidated gains and sought to extend its right flank eastward across the Jordan River. The successful Battle of Tell 'Asur and occupation of the Jordan Valley provided the operational basis for a push into Transjordan to threaten Ottoman communications at Amman.

Event

Between 21 March and 2 April 1918, British Empire forces crossed the Jordan River under fire, established a bridgehead, captured Es Salt, and advanced on Amman with the Anzac Mounted Division, Imperial Camel Corps Brigade, and infantry from the 60th London Division. A determined assault on Amman's Ottoman garrison failed when railway-delivered reinforcements strengthened the defenders beyond what the attacking force could overcome.

Consequence

General Shea's force was compelled to retire from both Amman and Es Salt back to the Jordan Valley by 2 April 1918. The EEF continued to hold the Jordan Valley through summer 1918, but the failure to take Amman left Ottoman control of the Hejaz Railway intact until the broader Battle of Megiddo offensive in September 1918.
