Australian Imperial Force

Australian Imperial Force. The Australian Imperial Force was the principal expeditionary military force of Australia during the First World War. Formed shortly after the outbreak of war in August 1914, it fought alongside other British Empire forces, most notably those of New Zealand within the Australian and New Zealand Army Corps. The force was raised entirely from volunteers and became renowned for its combat effectiveness and distinctive national character.

Formation and early history

The Australian government, led by Prime Minister Andrew Fisher, pledged full support to Britain following the declaration of war. The initial contingent was rapidly assembled at training camps like Broadmeadows and Liverpool, with the first convoy departing Albany in November 1914. Under the command of General William Birdwood, the force underwent further training in Egypt before its first major combat deployment. This early period was marked by the integration of the force into the imperial command structure and the forging of its identity separate from the pre-war Citizen Military Forces.

Organisation and structure

The force was organised into infantry divisions, beginning with the 1st Division, 2nd Division, and later the 3rd Division, 4th Division, and 5th Division. Each division comprised three brigades, along with supporting units of artillery, light horse, engineers, and medical corps. The Australian Flying Corps served as the air arm, while the Royal Australian Navy operated independently. Administration and logistics were managed through a complex system of depots in Australia, Egypt, and England, including the vital ANZAC Mounted Division.

Major campaigns and battles

The force first saw action during the Gallipoli Campaign, landing at Anzac Cove on 25 April 1915. Following the evacuation from Gallipoli, it was redeployed to the Western Front, where it fought in many of the war's most gruelling battles. These included the Battle of the Somme, particularly at Pozières and Mouquet Farm, the Battle of Passchendaele, and the Battle of Messines. In 1918, under the command of General John Monash, it played a pivotal role in the Hundred Days Offensive at battles like Amiens and the Battle of Mont Saint-Quentin. Concurrently, the Light Horse regiments were engaged in the Sinai and Palestine Campaign against the Ottoman Empire.

Recruitment and conscription

Initially, recruitment was robust, with thousands enlisting at centres across the country, spurred by patriotic fervour. As casualty lists grew, maintaining numbers became challenging. The government, under Prime Minister Billy Hughes, held two national plebiscites on conscription in 1916 and 1917, both of which were narrowly defeated. This created significant domestic political and social division, pitting Hughes and his supporters against the Australian Labor Party and anti-conscription groups. Consequently, the force remained an all-volunteer army for the duration of the conflict, though its numbers were supplemented by reinforcements from the existing pool of volunteers.

Demobilisation and legacy

Following the Armistice of 11 November 1918, soldiers began a gradual return to Australia, a process managed by the Repatriation Department. Many faced significant challenges reintegrating into civilian life, leading to the establishment of support organisations like the Returned and Sailors' Imperial League of Australia. The collective experience profoundly shaped national consciousness, with Anzac Day becoming the central day of remembrance. The force was officially disbanded in 1921, but its traditions and battle honours were perpetuated by the Australian Army in the interwar period and beyond, influencing military doctrine and national identity for generations.
