History
Formation
The Imperial Mounted Division was formed in Egypt in 1917 by bringing together two Australian Light Horse brigades, two British Yeomanry brigades, and a British horse artillery brigadeTemplate:Efn (four batteries).<ref name="Perry56">Template:Harvnb</ref> These units were:
- The 3rd Light Horse Brigade was formed in Australia in October 1914 with the 8th, 9th, and 10th Light Horse Regiments and was posted to Egypt in March 1915. It was dismounted and served in Gallipoli from May to December attached to the New Zealand and Australian Division<ref name=Perry51>Template:Harvnb</ref> (notably the Battle of Sari Bair).<ref name=Perry41>Template:Harvnb</ref> It joined the ANZAC Mounted Division when it was formed in March 1916<ref name=Perry51/> and saw action with it at the battles of Romani and Magdhaba.<ref name=Perry52>Template:Harvnb</ref> It joined the division on formation in January 1917; it was replaced in the ANZAC Mounted Division by the British 22nd Mounted Brigade.<ref name=Perry51/>
- The 4th Light Horse Brigade was formed in Australia in February 1915 with the 11th, 12th, and 13th Light Horse Regiments and was posted to Egypt in July 1915. The brigade was broken up:<ref name=Perry55>Template:Harvnb</ref> the 11th Light Horse Regiment was dismounted and served in Gallipoli as reinforcements to other regiments;<ref name=11lhr>Template:Cite web</ref> the 12th Light Horse Regiment was dismounted and attached to the 3rd Light Horse Brigade in Gallipoli (AugustTemplate:SndDecember 1915) and 2nd Light Horse Brigade in Egypt (April 1915Template:SndJanuary 1917);<ref name=Perry40>Template:Harvnb</ref> and the 13th Light Horse Regiment remained mounted and joined the 2nd Australian Division. The brigade was reformed in January 1917Template:Sndwith the 4th Light Horse Regiment in place of the 13thTemplate:Snd and joined the division on formation.<ref name=Perry55/>
- The 5th Mounted Brigade was formed as part of the Territorial Force in 1908 as the 1st South Midland Mounted Brigade with three yeomanry regiments: the Warwickshire Yeomanry, the Royal Gloucestershire Hussars and the Queen's Own Worcestershire Hussars.<ref name=Westlake15>Template:Harvnb</ref> Shortly after the outbreak of war, it was assigned to the 2nd Mounted Division and moved to Egypt in April 1915. It was dismounted in August 1915 and took part in the Gallipoli Campaign as 1st Mounted Brigade, notably the Battle of Scimitar Hill. Due to losses and wastage during August 1915, it formed a battalion sized unitTemplate:Snd1st South Midland RegimentTemplate:Sndin 1st Composite Mounted Brigade. It returned to Egypt in December where it was reformed and remounted.<ref name=Becke1017>Template:Harvnb</ref> The 2nd Mounted Division was broken up in January 1916 and it served as Corps Troops from 21 January 1916 (numbered as 5th Mounted Brigade from April). It joined the division on formation.<ref name=Perry55/>
- The 6th Mounted Brigade was likewise formed as part of the Territorial Force in 1908 as the 2nd South Midland Mounted Brigade with three yeomanry regiments: the Royal Buckinghamshire Hussars, the Berkshire Yeomanry and the Queen's Own Oxfordshire Hussars.<ref name=Westlake15/> On 19 September 1914, the Queen's Own Oxfordshire Hussars was posted to the BEF, joining the 4th Cavalry Brigade in France.<ref name=LLT_QOOH>Template:Cite web</ref> The Queen's Own Dorset Yeomanry joined in the same month to replace them.<ref name=LLT_QODY>Template:Cite web</ref> The brigade's early service was identical to the 5th Mounted Brigade until January 1916 when it joined the Western Frontier Force.<ref name=Becke1017/> It joined the division on formation.<ref name=Perry55/>
- XIX Brigade, Royal Horse Artillery (T.F.) was formed for the division in January 1917 with four British Territorial Force horse artillery batteries: the 1/1st Berkshire and 1/1st Nottinghamshire Batteries of the Royal Horse Artillery, and 1/A and 1/B Batteries of the Honourable Artillery Company.<ref name=Perry54>Template:Harvnb</ref> All four batteries had originally gone out to Egypt with the 2nd Mounted Division in April 1915, but did not proceed to Gallipoli with the division. Instead, they variously served on the Suez Canal Defences,<ref name=Becke16>Template:Harvnb</ref> as part of the Western Frontier Force in the Senussi Campaign,<ref name=Frederick449>Template:Harvnb</ref> or in Aden where 1/B Battery HAC and 1/1st Berkshire RHA fought a sharp action at Sheikh Othman that removed the Turkish threat to Aden for the rest of the war.<ref name=Farndale357>Template:Harvnb</ref> They rejoined 2nd Mounted Division on its return from Gallipoli in December 1915,<ref name=Becke17>Template:Harvnb</ref> however, the dismemberment of the division began almost immediately as units were posted to the Western Frontier Force, Suez Canal Defences or to various other commands.<ref name=Becke16/> Initially, each battery was equipped with four<ref name=Westlake3>Template:Harvnb</ref> Ehrhardt 15-pounder guns<ref name=Clarke23>Template:Harvnb</ref> but were re-equipped with more modern 18 pounders (four per battery) in time for the First Battle of Gaza (26Template:Snd27 March 1917).<ref name=Farndale83>Template:Harvnb</ref> In practice, the batteries were tactically attached to the mounted brigades, for example, 1/1st Nottinghamshire RHA to the 3rd Light Horse Brigade<ref name=3alhb>Template:Cite web</ref> and 1/A Battery HAC to the 4th Light Horse Brigade.<ref name=4alhb>Template:Cite web</ref>
The division was also provided with support units, mostly assigned or attached directly to the brigades, but including an engineer squadron, a signals squadron, and train.<ref name=Perry54/>
