Australian Light Horse
Australian Light Horse were mounted troops with characteristics of both cavalry and mounted infantry, who served in the Second Boer War and World War I. During the inter-war years, a number of regiments were raised as part of Australia's part-time military force. These units were gradually mechanised either before or during World War II, although only a small number undertook operational service during the war. A number of Australian light horse units are still in existence today.
The Australian Light Horse was established as the outcome of a debate that took place in military circles in Australia in the late 19th – early 20th centuries concerning the future of mounted troops.[1] The example of the Franco-Prussian War illustrated that the battlefield had become dominated by massed land armies supported by artillery. For Australia the reality was vast spaces with sparse populations making it difficult to consider anything that remotely looked like the European model. The 1890s were wracked by drought and depression ensuring that none of the states were able to afford anything but the most token of armies supported by a large contingent of volunteers.
The Second Boer War provided the short term answer. While Australian forces fought against the Boers in South Africa, the Boer methodology of conducting war was considered to be the answer for Australian defence. Volunteer Light Horse Regiments were established around Australia supported by the Rifle Club movement which provided semi trained reinforcements for the various formations. Should these formations be called upon to defend Australia, the local commander was charged with maintaining resistance through the use of the Commando formation which envisaged a large scale guerrilla war. The prospect of an endless and strength-sapping guerrilla war was the key deterrent factor which relied heavily upon mobile soldiers. The mounted infantry remained the key to the Australian defence posture until the Kitchener Report of 1910 (Archived 17 June 2008 at the Wayback Machine) which envisaged formations that could be slotted directly into an Imperial expeditionary force. The plan envisaged two mounted divisions.
By the outbreak of World War I, there were 23 light horse regiments within Australia's part-time military force, consisting of 9,000 personnel.[1] These were organised as follows:[2][3]
After the war, the light horse regiments were distributed as follows:[27]
These cavalry brigades were organised into two cavalry divisions: the 1st and 2nd.[17]
At the outbreak of World War II, there were 25 light horse regiments. Of these, 17 were still horsed although they had been partially mechanised, while four had been converted to machine gun regiments and two had been converted to armoured car regiments.[28] Throughout the war, the various light horse units were converted to motorised infantry, armoured car or armoured regiments, serving mainly in the defence of Australia. As the threat of invasion passed, though, most were disbanded in 1943 or 1944 and their personnel redistributed amongst other units. By 1945, only two units remained. The first of these was the 20th Light Horse Regiment, which as the 20th Motor Regiment, served overseas, at Merauke, and was later converted into a pioneer regiment. The second unit was the 1st Light Horse Regiment, which became the 1st Tank Battalion, and as such fought in New Guinea and Borneo.[28]
