The 12th Light Horse Regiment was a mounted unit of the Australian Army. It was raised in New South Wales in 1915 as part of the Australian Imperial Force (AIF) for service during the First World War. After fighting at Gallipoli as reinforcements, the regiment served in the Sinai and Palestine campaign against the Ottoman Empire, seeing action in several notable battles including Beersheba, the capture of Jerusalem, Megiddo and the capture of Damascus. In the aftermath of the war, the regiment was used to suppress the 1919 Egyptian Uprising, before being disbanded in late 1919.

The Capture of Damascus occurred on 1 October 1918 after the capture of Haifa and the victory at the Battle of Samakh which opened the way for the pursuit north from the Sea of Galilee and the Third Transjordan attack which opened the way to Deraa and the inland pursuit, after the decisive Egyptian Expeditionary Force (EEF) victory at the Battle of Megiddo during the Sinai and Palestine Campaign of World War I. Damascus was captured when Desert Mounted Corps and Prince Feisal's Sherifial Hejaz Army encircled the city, after a cavalry pursuit northwards along the two main roads to Damascus. During the pursuit to Damascus, many rearguards established by remnants of the Ottoman Fourth, Seventh and Eighth Armies were attacked and captured by Prince Feisal's Sherifial Army, Desert Mounted Corps' Australian Mounted Division the 4th and the 5th Cavalry Divisions. The important tactical success of capturing Damascus resulted in political manoeuvring by representatives from France, Britain and Prince Feisal's force.
