As mounted infantry, the regiment rode into battle on their horses but were expected to dismount and fight on foot. The regiment fought predominantly against the forces of the Ottoman Turkish Empire. Their first engagement was in the Gallipoli Campaign between May and December 1915, during which they participated in the largest battle of that theatre at Chunuk Bair and the fighting for Hill 60. Evacuated to Egypt, the regiment took part in the Sinai and Palestine Campaign from 1916 to 1918. Their early battles included Romani, Gaza and Beersheba. Later in the war, they were part of the force that occupied the Jordan Valley and took part in the raids on Amman and Es Salt. Their final wartime operation was in connection with the capture of the Turkish Fourth Army. During the four years of war, the regiment sustained 334 dead from all causes and 555 wounded, several of those more than once. After the war, the regiment played a minor role in the Egyptian Revolution of 1919 before it was disbanded in June 1919.
