Yeomanry Mounted Division was a British mounted formation active during the First World War, formed in the Egyptian Expeditionary Force and engaged in the Sinai and Palestine Campaigns. It operated alongside formations such as the Desert Mounted Corps, XXI Corps and ANZAC Mounted Division in operations that included the Third Battle of Gaza and the Battle of Beersheba, and involved coordination with elements of the Imperial Camel Corps and Royal Air Force units.

Formation and Organization

The division was established in 1917 within the Egyptian Expeditionary Force under the overall command structures led by General Sir Archibald Murray and later General Edmund Allenby, drawing mounted regiments from British yeomanry brigades previously deployed in the Gallipoli Campaign and on the Western Front. Its formation reflected strategic shifts after the Battles of Gaza and the reorganization following losses sustained around Gaza and Beersheba, incorporating units transferred from the Territorial Force and aligned with the operational doctrines of mounted warfare developed during the Anglo-Egyptian efforts in Sudan, the Boer War and colonial policing actions. Administrative arrangements connected the division to GHQ in Cairo, the British Expeditionary Force logistics networks, and communications nodes used by the Royal Corps of Signals and Royal Army Service Corps.

Operational History

Deployed in the Sinai and Palestine Campaign, the division participated in operations linked to the capture of Beersheba and the subsequent pursuit toward Jerusalem, coordinating maneuvers with the Desert Mounted Corps under Lieutenant General Sir Harry Chauvel and infantry formations including the 52nd (Lowland) Division and 53rd (Welsh) Division. It undertook reconnaissance, screening and mounted charges in actions contemporaneous with the Third Battle of Gaza and the Battle of Jaffa, while engaging Ottoman units from the Yildirim Army Group and elements commanded by General Erich von Falkenhayn. The division's operational tempo involved cooperation with the Royal Flying Corps and later Royal Air Force reconnaissance squadrons, Royal Horse Artillery batteries, and armoured car units supporting advances toward Ramleh, Lydda and the Jordan Valley during the wider Palestine Campaign.

Composition and Units

The division comprised yeomanry brigades drawn from regiments such as the Royal Buckinghamshire Yeomanry, North Somerset Yeomanry, Hertfordshire Yeomanry, and Hampshire Yeomanry, alongside attached Royal Horse Artillery batteries and support from the Royal Engineers field companies. Other constituent regiments included the Warwickshire Yeomanry, Nottinghamshire Yeomanry (Sherwood Rangers), and the Yorkshire Yeomanry contingents, augmented by units from the Imperial Camel Corps, the Machine Gun Corps and the Army Service Corps. Medical support was provided by Royal Army Medical Corps field ambulances, veterinary sections from the Army Veterinary Corps, and dental detachments, working with supply depots coordinated by the Army Pay Corps and ordnance elements of the Royal Army Ordnance Corps.

Training and Equipment

Training emphasized mounted reconnaissance, sabre and carbine tactics, dismounted infantry action, and desert navigation techniques developed in conjunction with cavalry schools and training centers influenced by doctrines from the Cavalry School at Netheravon and the Mounted Infantry training used in the Boer War and North African expeditions. Equipment included pattern 1908 cavalry swords, Lee-Enfield rifles, Vickers machine guns issued via the Machine Gun Corps, 13-pounder and 18-pounder Royal Horse Artillery guns, choirs of signalling equipment from the Royal Corps of Signals, and transport vehicles maintained by the Mechanical Transport Corps and Army Service Corps. Logistical challenges required water supply planning with Royal Engineers wells parties and camel transport coordination alongside horse veterinary practices informed by the Army Veterinary Corps and veterinary research from the Royal Veterinary College.

Command Structure and Notable Commanders

Placed under the Egyptian Expeditionary Force command and operationally coordinated with Desert Mounted Corps, the division served in chains of command involving commanders such as Lieutenant General Sir Harry Chauvel and divisional commanders who liaised with corps commanders including General Edmund Allenby and Lieutenant General Philip Chetwode. Senior staff officers included brigade commanders drawn from Territorial Force leadership and regular army officers experienced in cavalry operations, many of whom had prior service with regiments like the Household Cavalry, 19th Royal Hussars and 13th Hussars and had been involved in campaigns honored with awards such as the Distinguished Service Order and Victoria Cross recipients from related theatres.

Disbandment and Legacy

Following reorganization in 1918, many yeomanry regiments were converted to different roles, amalgamated into the Machine Gun Corps, or absorbed into newly formed armoured and reconnaissance units as part of post-war reductions and the Territorial Force reconstitution; the division itself was broken up with personnel redistributed to formations including the 1st and 2nd Mounted Divisions and later Territorial Army cavalry brigades. Its legacy influenced interwar British cavalry doctrine, the mechanisation debates involving the Royal Tank Corps and Royal Armoured Corps, and regimental histories preserved by county museums and the Imperial War Museum, with battle honors from the Sinai and Palestine Campaign retained by successor yeomanry regiments and commemorated in memorials at locations such as Jerusalem and Beersheba.
