History
First World War
Gallipoli
The Australian 1st Division was raised during the initial formation of the
Australian Imperial Force (AIF) on 15 August 1914, shortly after the outbreak of the First World War. The division consisted of around 18,000 men, organised into three

, although in January 1915, they were reorganised into the British four-company system. Its first commander was the senior Australian general and head of the AIF,
Major General William Bridges. Over the course of six weeks, the division's subordinate units were raised separately in the various states before embarking overseas. The transports then concentrated off the Western Australian coast and the combined fleet sailed for Britain. While en route, concerns about overcrowding in the training camps in the United Kingdom meant that the decision was made to land the division in Egypt, where it would complete its training before being transported to the
Western Front.

While in Egypt, the division was assigned to the
Australian and New Zealand Army Corps along with the
New Zealand and Australian Division. Following the Allied decision to force a passage through the
Dardanelles
The Dardanelles ( ; ; ), also known as the Strait of Gallipoli (after the Gallipoli peninsula) and in classical antiquity as the Hellespont ( ; ), is a narrow, natural strait and internationally significant waterway in northwestern Turkey th ...
, the division was allocated to take part in a landing on the
Gallipoli peninsula along with Anglo-French forces. The 1st Division made the initial
landing at Anzac Cove on 25 April 1915. The 3rd Brigade formed the covering force which landed first, around dawn. The 1st and 2nd Brigades followed, landing from transports, and all were ashore by 9:00 am. While the landing was lightly opposed on the beach by elements of a single Turkish battalion, the Australians were checked short of their objectives as Turkish reinforcements arrived to secure the high ground around Chunuk Bair and Sari Bair. Critical fights developed on the left, over the hill known as
Baby 700, and on the right on
400 Plateau, but stalemate set in and little further progress would be made for the remaining eight months of the campaign.
On 15 May 1915, after Bridges was mortally wounded by a sniper, an English officer,
Brigadier General Harold Walker was given temporary command while a replacement was dispatched from Australia. This was Colonel
James Legge

William Birdwood, or his subordinate brigade commanders. That same month, the division's artillery – three field artillery brigades each operating twelve 18-pound pieces, which had proved inadequate in the early battle, was boosted by the arrival of several Japanese-made trench mortars. They were later joined by several heavier guns including a 4.7-inch gun and two 6-inch howitzers. On 24 June, Legge replaced Walker, who returned to command of the 1st Brigade, but after Legge was evacuated from Gallipoli he was moved sideways to command of the newly formed
Australian 2nd Division and Walker resumed command of the 1st Division.
The 1st Division's role in the
August Offensive was to hold the front line and conduct a diversion on 400 Plateau at
Lone Pine on 6 August. The resulting battle was the only occasion when a significant length of the Turkish trench line was captured, but resulted in heavy casualties. The main assault was made by the 1st Brigade, which was later reinforced by the
7th and
12th Battalions. Out of an assault force of 2,900 men, 1,700 were killed or wounded. On 7 August, the
6th Battalion from the 2nd Brigade made an unsuccessful attempt to capture the German Officers' Trench as a preliminary operation to other assaults by light horsemen at
Quinn's Post and
the Nek.

Australian 1st Light Horse Brigade, Brigadier General
Harry Chauvel. The 1st Division was evacuated from the peninsula in December, returning to Egypt. During the early months of 1916 the AIF underwent a period of re-organisation and expansion, and the division's experienced personnel were used to provide cadre staff to the newly formed
4th and
5th Divisions before being brought back up to strength in preparation for deployment to the Western Front. On 14 March, Walker, having recovered from his wounds, resumed command of the division, now part of
I Anzac Corps. Seven members of the division received the

who intended to use the Australian divisions to take the village of
Pozières. Walker resisted Gough's efforts to throw the 1st Division into battle unprepared, insisting on careful preparation. When the 1st Division attacked shortly after midnight on 23 July, it succeeded in capturing half of the village but failed to make progress in the neighbouring German trench system. After enduring a heavy German bombardment, far surpassing anything yet experienced by an Australian unit, the 1st Division was withdrawn, having suffered 5,285 casualties, and was replaced by the Australian 2nd Division.
The division's respite was brief as in mid-August, with its battalions restored to about two-thirds strength, it returned to the line on Pozières Ridge, relieving the
Australian 4th Division and continuing the slow progress towards

and, on the night of 26 February, the 3rd Brigade captured the villages of Le Barque and Ligny-Thilloy. On the morning of 2 March, they withstood a German attempt to retake the villages. The 1st Division was then withdrawn to rest, joining the 4th Division. I Anzac's pursuit was carried on by the 2nd and
5th Divisions.
By April, the 1st Division (and I Anzac Corps) was once again part of Gough's
Fifth Army (formerly the Reserve Army). On 9 April – the day the British launched the
Battle of Arras – the 1st Division captured the last three villages (
Hermies,
Boursies and
Demicourt) used by the Germans as outposts of the Hindenburg Line, thereby bringing the British line in striking distance of the main Hindenburg defences. This action cost the division 649 casualties. For actions during the fighting at Boursies, Captain

The Germans, well aware of the vulnerable state of the British defences, launched a counter-stroke on 15 April (the
Battle of Lagnicourt). The Germans attacked with 23 battalions against four Australian battalions. The German plan was to drive back the advanced posts, destroy supplies and guns and then retire to the Hindenburg defences. However, despite their numerical superiority, the Germans were unable to penetrate the Australian line. The 1st Division's artillery batteries in front of Lagnicourt were overrun and the village was occupied for two hours but counter-attacks from the Australian 9th and
20th Battalions (the latter from the 2nd Division) drove the Germans out. In this action the Australians suffered 1,010 casualties, mainly in the 1st Division, against 2,313 German casualties. Only five artillery guns were damaged.
On 3 May the
Second Battle of Bullecourt commenced. Initially the 1st Division in reserve but it was drawn into the fighting on the second day when the 1st Brigade was detached to support the 2nd Division's attack. The Australians seized a foothold in the Hindenburg Line which over the following days was slowly expanded. By 6 May, they had captured over of the German trenchline, and the 3rd Brigade had also been committed. The German attempts to drive the British from their gains finally ceased on 17 May and the 1st Division was withdrawn for an extended rest, having suffered 2,341 casualties.

Polygon Wood. The Australian divisions suffered 5,000 casualties from the battle – the 1st Division lost 2,754 men – mainly due to retaliatory shelling from heavy artillery after the advance had completed.

This was completed by 23 March 1919, when the division was disbanded.

Inter war years
In 1921, after the AIF was disbanded, the part-time
Citizens Forces was re-organised to adopt the numerical designations of the AIF. Thus the 1st Division was re-raised as a reserve formation, initially under the command of Colonel Charles Brand, composed primarily of infantry units based in New South Wales and Queensland. During the inter-war years, the assignment of battalions to brigades and
divisions varied considerably within the Army and as a result the 1st Division's composition was changed a number of times; its initial order of battle included three infantry brigades – the 1st,

– as well as two field artillery regiments, one medium artillery regiment and two engineer field companies. At this stage the division was partly mobilised, although as the provisions of the ''Defence Act (1903)'' precluded the deployment of the Militia to fight outside of Australian territory, it was decided to raise an all volunteer force for overseas service. This force was known as the

, however, in December 1941 members of the Militia were prevented from joining the AIF and were called up for full-time service to bolster defences in Australia in an effort to counter the possibility of attacks by
Japanese land forces against the Australian mainland. Later a number of Militia formations took part in the fighting against the Japanese in the Pacific, notably in New Guinea and Borneo, however, the 1st Division remained in Australia throughout the war. Based in New South Wales, the division formed part of the Port Kembla Covering Force during the early stages of the Pacific War and in March 1942 became part of the
II Corps,
First Army.
During this time the division's composition changed numerous times as many of its subordinate units were transferred. Shortly after mobilisation the division lost its engineer field companies and in June 1940 the three artillery regiments assigned to the division were also transferred out, to be replaced by a light horse regiment which had been converted to the machine gun role although this too was later removed from the division's order of battle. In mid-1942, the division's headquarters staff were transferred along with their commander, Major General Cyril Clowes, to

Battle of Milne Bay. Later the division was transferred to the
Second Army. By April 1943, the division consisted of the 1st,
9th and
28th Brigades, and was headquartered in Parramatta. As manpower restrictions in the Australian economy forced the early demobilisation of large numbers of men, the majority of which came from infantry units in Australia that were not involved in fighting overseas. The 1st Division was one of these units and by January 1945, when the 2nd Brigade was disbanded, the division consisted of only one infantry brigade, the 1st. The division was officially disbanded on 6 April 1945.

. By 1948 this process had been completed and a period of reorganisation began. This resulted in the establishment of a Regular infantry force consisting of a single brigade and two divisions of part-time soldiers in the Citizens Military Force (CMF). There was no room within this structure for the 1st Division and as a result it remained off the Australian Army's order of battle until 1960, when its headquarters was reformed in Sydney, following the implementation of the
Pentropic divisional structure, commanding all Army units – Regular and CMF – in New South Wales. It was also responsible for training some CMF units in other states.
In 1965, the Pentropic structure was abolished and the divisional headquarters' was tasked with determining the readiness of units deploying to

Forces Command, in 2009, and the implementation of the "Adaptive Army" initiative it was decided that no combat units would be directly assigned to the 1st Division on a permanent basis. Instead, it was decided that all combat forces would be assigned to Forces Command and the Headquarters 1st Division would provide a command and control function for "high-level training activities", during which activities combat units would be force assigned to the division.
