Overview
The 9th Division was an Australian Army formation created during the Second World War as the fourth division raised for the Second Australian Imperial Force. Unlike most other Australian divisions, it was formed in the United Kingdom from Australian infantry brigades and support units that had been sent overseas during 1940, when Britain faced the possibility of a German invasion after the fall of France. The division subsequently became one of Australia's most distinguished wartime formations. Its early organization changed considerably. The division initially included the 18th and 25th Brigades, with the 24th Brigade later assigned to it. Major General Henry Wynter was its first commander, but illness led to his replacement by Major General Leslie Morshead in January 1941. As the Australian force in the Middle East was reorganized, the 18th and 25th Brigades were transferred to the 7th Division and replaced by the 20th and 26th Brigades. The division's headquarters moved to the Middle East in February 1941, and its units underwent further training and preparation in Palestine and the surrounding region. The division first entered combat in North Africa. It was sent to Cyrenaica in Libya in early 1941, although shortages of transport, artillery, anti-tank weapons and other equipment limited its initial effectiveness. During the rapid Axis advance in March and April, the division conducted difficult withdrawals toward Tobruk. Rear-guard actions, including the fighting at Er Regima Pass and Mechili, marked its first major encounters with German forces. Elements of the division reached Tobruk on 9 April 1941 and became the principal Australian component of the Allied garrison during the ensuing siege. At Tobruk, the 9th Division defended a fortified perimeter against repeated German and Italian attacks. Its defensive system combined fixed fortifications, aggressive patrols and raids, artillery support, and determined local counterattacks. The division's soldiers helped prevent the port from being captured until the garrison was relieved late in 1941. John Edmondson was awarded the Victoria Cross posthumously for his conduct during the siege, the first of seven Victoria Crosses awarded to members of the division during the war. Most of the division was withdrawn during September and October 1941, while the 2/13th Battalion remained until the final relief of the garrison in December. The Tobruk fighting caused the division more than 3,000 casualties, including killed, wounded and prisoners. After a short period in Palestine, the division was deployed to northern Syria for frontier security and mobile-warfare training. In 1942, although the 6th and 7th Divisions were recalled to Australia following Japan's entry into the war, the Australian government agreed to keep the 9th Division in the Middle East for a time. It was then moved to Egypt and committed to the First Battle of El Alamein in July 1942. The division attacked in the northern sector, captured important ground around Tel el Eisa and took large numbers of prisoners. Its operations also resulted in the capture of a German signals-intelligence unit that had been supplying valuable information to Axis commanders. The division sustained heavy losses in subsequent attacks, including the costly fighting around Ruin Ridge. The 9th Division remained in the El Alamein line and played a major role in the Second Battle of El Alamein in October and November 1942. Positioned near the coast, it helped draw German and Italian reinforcements toward the northern sector and made important gains against Axis positions. Its assault formations suffered severe casualties, but its pressure contributed to the wider Allied breakthrough and the eventual Axis withdrawal from Egypt. The division then returned to Australia, arriving during early 1943 after a prolonged overseas deployment. In the Pacific, the division took part in the New Guinea campaign during 1943 and 1944, including operations in the Lae and Huon Peninsula areas. It later served in the Borneo campaign in 1945, conducting amphibious and land operations against Japanese forces at locations including Tarakan, Brunei Bay and Balikpapan. The division was disbanded in early 1946 after the end of the war. Its reputation rested on its unusually long cumulative period in front-line combat, its record of decorations, and the respect it received from commanders on both Allied and Axis sides. It was one of only a small number of Allied army divisions to serve in both the Mediterranean and Pacific theatres.
History
The 9th Division was established in the United Kingdom in late 1940 as the fourth division of the Second Australian Imperial Force. Its initial personnel came from Australian brigades and supporting formations already dispatched to Britain to reinforce the country's defenses after the German victory in France. The 18th and 25th Brigades were initially assigned to the division, with the 24th Brigade joining later. Major General Henry Wynter commanded the formation at first, but illness resulted in Major General Leslie Morshead taking command in January 1941. A reorganization of the Australian divisions in early 1941 transferred the 18th and 25th Brigades to the 7th Division. The 20th and 26th Brigades replaced them, and the division's headquarters moved to the Middle East. After further training in Australia, Britain and Palestine, the division was sent to Cyrenaica in Libya. Its deployment was affected by shortages of weapons, transport and supporting arms. When German-led Axis forces launched an offensive in March 1941, the division conducted a series of withdrawals and rear-guard actions toward Tobruk. The fighting at Er Regima Pass demonstrated both the determination of the Australian infantry and the vulnerability created by limited mobility and equipment. The division entered Tobruk on 9 April 1941. During the siege, its brigades defended the port and surrounding perimeter against repeated Axis attacks. Australian forces used the existing Italian defenses, aggressive patrolling, artillery and local counterattacks to prevent a German capture. The division's casualties included those incurred in the defense of the fortress and in attempts to hold or recover forward positions. John Edmondson received a posthumous Victoria Cross for actions during the siege. Most of the division was evacuated in stages in September and October, although the 2/13th Battalion remained with the garrison until its relief in December. Following its withdrawal, the division spent a short period in Palestine and then moved to northern Syria. There it guarded the Turkish-Syrian frontier and conducted training intended to improve its ability to fight a mobile campaign. In 1942, the division remained in the Middle East after the 6th and 7th Divisions were returned to Australia. It was moved from Syria to Egypt in response to the Axis advance and reached the El Alamein area in July. During the First Battle of El Alamein, the division attacked in the northern part of the Allied line. Its operations around Tel el Eisa captured important high ground and many prisoners, but later attacks produced heavy casualties. The capture of a German signals-intelligence formation disrupted an important source of Axis information. The division remained in the front line through the subsequent months of static defense, patrols and raids. In the Second Battle of El Alamein, the 9th Division again operated near the coast. Its attacks compelled German and Italian commanders to reinforce the northern sector, thereby contributing to the wider Allied plan. The division made significant local gains, although its battalions were reduced by sustained losses and some formations required relief or rebuilding. After the battle, the division returned to Australia in early 1943. Its later service took place in the Pacific. During 1943 and 1944 it fought in the New Guinea campaign, including operations in the Lae and Huon Peninsula regions. In 1945 it participated in the Borneo campaign, where Australian forces conducted amphibious assaults and subsequent ground operations against Japanese positions. The division was disbanded early in 1946. Its wartime record made it one of the Australian Army's most decorated formations and one of the few Allied divisions to serve in both the Mediterranean and Pacific theatres. It also accumulated an exceptionally long period of front-line combat compared with other Australian divisions.
