The 10th Duke of Cambridge’s Own Lancers (Hodson’s Horse) was stationed at Loralai in Balochistan under the 4th (Quetta) Division, when the First World War broke out in August 1914. It had arrived from Jullundur on 18 November 1912 and had detachments at Gumbaz, Maratangi, Murgha and Musa Khel. While the regiment did not proceed overseas until 1916, the Regiment supplied drafts of officers and men to other cavalry regiments. Over 350 officers and men of the Regiment were sent abroad, before the 10th Lancers received orders to mobilize for service in Mesopotamia in August 1916, the first two squadrons arriving in September and the other two squadrons and headquarters in October 1916. The 10th Lancers initially served as part of the Tigris Defences, guarding the lines of communication between Amara and Sheikh Sa’ad. The Regiment spent the next four years serving in Mesopotamia, but it would be during the Iraqi revolt of 1920, that the 10th Lancers suffered its heaviest casualties. On 3 September 1920, an armoured train at Samawa which was guarded by ‘D’ Squadron was overwhelmed and the 10th Lancers lost 28 men. The Regiment left Mesopotamia on 30 October 1920 and returned to India.
