By November 1916 Cheshire Yeomanry knew that it was to be formed into an infantry battalion. However, because the establishment of an infantry battalion was so much greater than that of a cavalry regiment it would be necessary for some amalgamations to create new battalions. Cheshire Yeomanry were to amalgamate with Shropshire Yeomanry to form a Battalion of the King’s Shropshire Light Infantry, and the yeomanry regiments undertook a period of infantry training in preparation for their new role.
On 1 March 1917 Shropshire Yeomanry arrived from Sherira at Helmieh Camp, Zietoun, near Cairo. The following day Cheshire Yeomanry arrived at the camp from Alamein. Here the regiments amalgamated to form 10th (Shropshire & Cheshire Yeomanry) Bn. King's Shropshire Light Infantry.
On 14 January 1917, the General Officer Commanding (GOC) Egyptian Expeditionary Force Sir Edmund Allenby had given orders for the reorganisation of the 2nd, 3rd and 4th Dismounted Brigades of Yeomanry and for their redesignation as the 229th, 230th and 231st Infantry Brigades. The Brigades were organised as the 74th (Yeomanry) Division under Major-General E.S. Girdwood and began to assemble on 4 March 1917 near El Arish.
