The 3rd Light Horse Regiment was a mounted infantry regiment of the Australian Army during the First World War. The regiment was raised in September 1914, and by December as part of the 1st Light Horse Brigade had moved overseas. The regiment only fought against the forces of the Ottoman Empire, in Egypt, at Gallipoli, on the Sinai Peninsula, and in Palestine and Jordan. After the armistice the regiment eventually returned to Australia in March 1919. For its role in the war the regiment was awarded nineteen battle honours. During the inter-war years, the regiment was re-raised as a part-time unit based in the state of South Australia. It was later converted to a reconnaissance squadron during the Second World War but was disbanded in early 1943 without having been deployed overseas. In the post war period, the regiment was re-raised as an amalgamated unit, designated the 3rd/9th Light Horse (South Australian Mounted Rifles), which is currently part of the Australian Army Reserve. Formation On 17 August 1914, the 3rd Light Horse Regiment was raised in Adelaide, South Australia and in Hobart, Tasmania. It had an establishment of twenty-five officers and 497 other ranks serving in three squadrons, each of six troops. Each troop was divided into eight sections, of four men each. In action one man of each section, was nominated as a horse holder reducing the regiment's rifle strength by a quarter. Once formed the regiment was assigned to the 1st Light Horse Brigade serving alongside the 1st and 2nd Light Horse Regiments. All Australian Light Horse regiments used cavalry unit designations, but were mounted infantry armed with rifles, not swords or lances, and mounted exclusively on the Australian Waler horse. Operational history Gallipoli In October 1914, the regiment left Australia, bound for the Middle East. After arriving in Egypt in December, they took part in the North African campaign defending the Suez Canal. They remained there until May 1915, when they left for the Gallipoli campaign with the Australian and New Zealand Army Corps (ANZAC). The regiment left their horses in Egypt, and arrived at the Gallipoli peninsula on 12 May 1915. Here regiment fought in the Landing at Anzac Cove, and the Battle of Sari Bair, but spent most of the campaign in a defensive posture. The regiment left Gallipoli for Egypt in December 1915, by which time they had earned four battle honours. Sinai and
