Staffordshire Yeomanry The Staffordshire Yeomanry ( Queen ' s Own Royal Regiment ) was a unit of the British Army . Raised in 1794 following Prime Minister William Pitt ' s order to raise volunteer bodies of men to defend Great Britain from foreign invasion , the Staffordshire Yeomanry began as volunteer cavalry regiment . It first served overseas at the time of the Boer War . Following distinguished action in Egypt and Palestine in the First World War , it developed with the deployment of artillery and tanks . From 1971 , the Regiment formed part of the Mercian Yeomanry , renamed The Queen ' s Own Mercian Yeomanry in 1973 . From 1992 it amalgamated with The Duke of Lancaster ' s Own Yeomanry to form The Royal Mercian and Lancastrian Yeomanry , and as such it remains today a yeomanry regiment of the Territorial Army . In October 2006 , the RMLY became a single cap badge regiment , when the individual cap badges of each squadron were replaced by the newly designed RMLY cap badge . The Regiment currently serves in the armoured replacement role , providing replacement tank crews for regular armoured regiments . World War I . The Staffordshire Yeomanry , after a short period of training at Diss , Norfolk with the North Midland Mounted Brigade , was ordered to join the Egyptian Expeditionary Force in 1915 . The Regiment was attached to the 22nd Mounted Brigade , Yeomanry Mounted Division in the Sinai and Palestine Campaign against the Ottoman Turkish and German army 1916 - 1918 . It fought in the indecisive First Battle of Gaza and Second Battle of Gaza in March and April 1917 . They finally won through in the Third Battle of Gaza in October 1917 and the crucial follow up Battle of Beersheba on 6 November 1917 , where Allied victory at last left the field open for the capture of Jerusalem on 9 December 1917 . In July 1918 the Division was reformed as the Fourth Cavalry Division under the command of General Allenby and the Regiment played a key role in the decisive Battle of Megiddo ( 1918 ) . The 1 / 1st Staffordshire Yeomanry joined the Desert Mounted Corps under the Australian General Henry George Chauvel and took part in his strategic cavalry ‘ bound ’ from the desert through Beisan , a forced march which covered an epic 87 miles in 33 hours : a record in cavalry history . After resting four days during which they took 5 , 800 prisoners , they converged with the spearhead of the Allied advance and made a triumphal entry into the Syrian city of Damascus with Allenby on 1 October 1918 . After a week , the Regiment started on a 200 - mile trek to Aleppo , having been reduced to just 75 men , 200 of them having become casualties from malignant malaria caught in the Jordan valley . However , Aleppo was captured on 25 October 1918 . Five days later , Turkey surrendered . World War II . In 1939 , the Staffordshire Yeomanry was part of the 6th Cavalry Brigade , 1st Cavalry Division , with the Warwickshire Yeomanry and Cheshire Yeomanry .
