3rd Light Horse Brigade

3rd Light Horse Brigade. The 3rd Light Horse Brigade was a mounted infantry formation of the Australian Imperial Force that served with distinction in the Middle Eastern theatre of World War I. Raised in 1914, it fought primarily in the Sinai and Palestine Campaign, participating in pivotal actions from the defence of the Suez Canal to the final offensive in Syria. The brigade was composed of regiments from New South Wales, Queensland, South Australia, and Tasmania, and was ultimately disbanded in 1919.

Formation and early history

The brigade was formed in Australia in August 1914 as part of the initial expansion of the First Australian Imperial Force following the outbreak of World War I. Its original constituent regiments were the 7th Light Horse Regiment, drawn from New South Wales, the 8th Light Horse Regiment from Victoria, and the 9th Light Horse Regiment from South Australia and Tasmania. After training in Egypt, the brigade was initially assigned to the New Zealand and Australian Division for the Gallipoli Campaign, but served in a dismounted role after the Australian Light Horse were deployed as infantry reinforcements. Following the evacuation from Gallipoli, the brigade returned to Egypt in December 1915 to reorganize and remount for desert warfare.

World War I

Upon returning to the Middle Eastern theatre, the brigade joined the ANZAC Mounted Division and played a crucial role in the Sinai and Palestine Campaign. It helped secure a decisive victory at the Battle of Romani in August 1916, a pivotal action that ended the Ottoman Empire's threat to the Suez Canal. The brigade subsequently participated in the advance across the Sinai Peninsula, including actions at Magdhaba and Rafah. During the First Battle of Gaza in March 1917, the brigade was involved in heavy fighting, and it later took part in the successful Third Battle of Gaza and the capture of Jerusalem. In 1918, the brigade was a key component in the victories at the Battle of Megiddo and the subsequent advance, culminating in the capture of Damascus and operations in Syria.

Structure and organization

As a standard light horse brigade, it typically consisted of three light horse regiments, a machine gun squadron, and a signal troop. The original regiments were the 7th Light Horse Regiment, 8th Light Horse Regiment, and 9th Light Horse Regiment. In early 1916, the 8th Light Horse Regiment was transferred and replaced by the 10th Light Horse Regiment, which was recruited from Western Australia. The brigade's machine gun support was provided by the 3rd Machine Gun Squadron, formed in 1917, and its signals were handled by the 3rd Signal Troop. For much of the war, the brigade operated as part of the ANZAC Mounted Division, alongside formations like the 1st Light Horse Brigade and the New Zealand Mounted Rifles Brigade.

Commanders

The brigade's first commander was Colonel (later Brigadier General) John Macquarie Antill, who had previously served as a staff officer to Major General William Bridges. Antill commanded during the Gallipoli Campaign and the early Sinai actions until February 1917. He was succeeded by Brigadier General John Robinson Royston, a South African officer with extensive experience from the Second Boer War, who led the brigade through the remainder of the Palestine campaign, including the battles of Gaza, Beersheba, and Megiddo. Other notable officers who served within the brigade included Lieutenant Colonel John Whitham of the 12th Light Horse Regiment, which was attached later in the war.

Battle honours

The brigade was awarded numerous battle honours for its service during World War I, reflecting its campaign from the deserts of Sinai to the hills of Palestine. These honours include Romani, Magdhaba–Rafah, Gaza–Beersheba, Jerusalem, Jordan, and Megiddo. The individual regiments within the brigade, such as the 9th Light Horse Regiment and the 10th Light Horse Regiment, also received specific honours for their actions at places like Beersheba and the the Nek. These honours are perpetuated by successor units within the Australian Army Reserve.
