Australian Mounted Division: The Imperial Cavalry of the Sinai and Palestine Campaign
The Australian Mounted Division, originally established as the Imperial Mounted Division, was a specialized military formation that played a pivotal role in the Middle Eastern theater of World War I. Active from January 1917 to May 1919, this division combined the unique capabilities of Australian light horsemen and British yeomanry to conduct high-mobility operations across the challenging terrains of Egypt, Sinai, and Palestine.
Operating as part of the Desert Column and later the Desert Mounted Corps within the Egyptian Expeditionary Force, the division was designed for versatility. It integrated mounted infantry—soldiers who used horses for rapid movement but typically fought on foot—with traditional cavalry roles to secure strategic objectives against Ottoman forces.

Formation and Composition
The division was formed in Egypt in January 1917. Its initial structure was a multinational effort, blending Australian and British forces to create a powerful mobile strike force.
The Australian Light Horse
The division initially included the 3rd Light Horse Brigade and the reconstituted 4th Light Horse Brigade. The 3rd Brigade had a storied history, having served dismounted at Gallipoli during the Battle of Sari Bair before returning to mounted operations. The 4th Brigade was reformed in early 1917, incorporating the 4th Light Horse Regiment to replace the 13th.
The British Yeomanry
The 5th and 6th Mounted Brigades provided the division's Yeomanry—volunteer cavalry from the British Territorial Force. These units, including the Warwickshire Yeomanry and the Royal Buckinghamshire Hussars, brought significant experience from the Gallipoli Campaign and the Western Frontier Force.
Artillery and Support
Firepower was provided by the XIX Brigade, Royal Horse Artillery (T.F.). This brigade consisted of four batteries, including the Honourable Artillery Company. Originally equipped with Ehrhardt 15-pounder guns, they were upgraded to 18-pounders in time for the First Battle of Gaza. The division was further supported by dedicated engineer and signals squadrons, as well as a divisional train for logistics.
Service History and Major Engagements
The division's operational history is defined by its participation in the Sinai and Palestine Campaign. During the First Battle of Gaza, the division served as a critical shield on the eastern flank, protecting the main infantry assault from counter-attacks and later acting as the rearguard during the withdrawal.
As the war progressed, the division participated in a series of decisive engagements that pushed Ottoman forces out of the region. Most notably, the division was central to the capture of Beersheba and the eventual fall of Damascus.

Evolution of Equipment and Structure
The division underwent significant changes in both weaponry and organization. Initially, the Light Horse were armed with rifles and bayonets, while the Yeomanry carried swords. By mid-1918, after the Yeomanry were redeployed to the Western Front, the Light Horse were also issued swords.
By July 1918, the division was redesignated as the Australian Mounted Division, reflecting a reorganization that replaced most British units with Australian ones, including the 5th Light Horse Brigade and the 1er Regiment Mixte de Cavalerie du Lavant.
