In April 1918 in response to the German spring offensive in France, every available man that could be spared was sent to reinforce the British Expeditionary Force on the Western Front.
The Desert Mounted Corps lost the majority of its yeomanry regiments, who were dismounted and retrained to serve as infantry or machine-gun companies.
This necessitated the disbandment of the Yeomanry Mounted Division.
Which could have had serious consequences on the corps future operations.
But the yeomanry were replaced in theatre by experienced British Indian Army cavalry regiments, that had been fighting in France since 1914.
Allenby used these new regiments to raise two new divisions.
The 4th Cavalry Division with the 10th Cavalry, 11th Cavalry and 12th Cavalry Brigades.
The 5th Cavalry Division was slightly different having the 13th Cavalry, 14th Cavalry and the 15th (Imperial Service) Cavalry Brigades.

Each of the cavalry brigades had one yeomanry and two Indian regiments, except the 15th (Imperial Service) Cavalry Brigade which had three regiments of Indian Imperial Service Troops.
With the move from the Sinai desert into southern Palestine there was now no need for a camel force.
In June the Imperial Service Camel Brigade was also disbanded, its battalions were instead mounted on horses and used to form the 5th Light Horse Brigade.
Which replaced the yeomanry 5th Mounted Brigade in the Australian Mounted Division, bringing that division back up to full strength.
The corps now comprised four divisions but had lost its mounted reserve force, and there was no increase in the ten horse artillery batteries, it did however gain its own infantry sub unit, the 20th Indian Brigade.
