The 10th Division was a division of the Australian Army, which served briefly during World War II. It was initially formed on 15 April 1942 from the Militia units of the Newcastle Covering Force. However, personnel shortages led to the division being disbanded in August that year.

Division (military) large military unit or formation

A division is a large military unit or formation, usually consisting of between 10,000 and 20,000 soldiers. Infantry divisions during the World Wars ranged between 8,000 and 30,000 in nominal strength.

Australian Army land warfare branch of Australias defence forces

The Australian Army is Australia's military land force. It is part of the Australian Defence Force (ADF) along with the Royal Australian Navy and the Royal Australian Air Force. While the Chief of the Defence Force (CDF) commands the ADF, the Army is commanded by the Chief of Army (CA). The CA is therefore subordinate to the CDF, but is also directly responsible to the Minister for Defence. Although Australian soldiers have been involved in a number of minor and major conflicts throughout its history, only in World War II has Australian territory come under direct attack.

World War II 1939–1945 global war

World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945. The vast majority of the world's countries—including all the great powers—eventually formed two opposing military alliances: the Allies and the Axis. A state of total war emerged, directly involving more than 100 million people from over 30 countries. The major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World War II was the deadliest conflict in human history, marked by 50 to 85 million fatalities, most of whom were civilians in the Soviet Union and China. It included massacres, the genocide of the Holocaust, strategic bombing, premeditated death from starvation and disease, and the only use of nuclear weapons in war.

In 1945, as plans were being made for an invasion of the Japanese home islands, the name 10th Division was revived for a proposed Australian contingent. It was to use personnel drawn from existing units of the Australian Imperial Force. The war ended before the invasion took place and the division was not formally re-raised.

Operation Downfall codename for the Allied plan for the invasion of Japan near the end of World War II

Operation Downfall was the proposed Allied plan for the invasion of Japan near the end of World War II. The planned operation was cancelled when Japan surrendered following the atomic bombings of Hiroshima and Nagasaki, the Soviet declaration of war, and the Soviet invasion of Manchuria. The operation had two parts: Operation Olympic and Operation Coronet. Set to begin in November 1945, Operation Olympic was intended to capture the southern third of the southernmost main Japanese island, Kyūshū, with the recently captured island of Okinawa to be used as a staging area. Later, in the spring of 1946, Operation Coronet was the planned invasion of the Kantō Plain, near Tokyo, on the Japanese island of Honshu. Airbases on Kyūshū captured in Operation Olympic would allow land-based air support for Operation Coronet. If Downfall had taken place, it would have been the largest amphibious operation in history.

Second Australian Imperial Force expeditionary force during World War II

The Second Australian Imperial Force was the name given to the volunteer personnel of the Australian Army in World War II. Under the Defence Act (1903), neither the part-time Militia nor the full-time Permanent Military Force (PMF) could serve outside Australia or its territories unless they volunteered to do so. The Second AIF fought against Nazi Germany, Italy, Vichy France and Japan. After the war, Australia's wartime military structures were demobilised and the 2nd AIF was disbanded, although a small cadre of its personnel became part of the Interim Army that was established in 1947, and from which the Australian Regular Army was formed in 1948.

History

Formation and disbandment

Following the start of the Pacific War, the Newcastle Covering Force, [1] [2] a Militia formation composed of the 1st and 32nd Brigades [3] under the command of Major General John Murray, [4] was renamed the 10th Division on 15 April 1942 following a complete re-organisation of the higher command of the Australian Army. [1] However, on 27 August 1942, personnel shortages caused the division to be disbanded. Australian Prime Minister John Curtin referred to this in a letter to Winston Churchill in October 1942, saying:

Pacific War theatre of war in the Second World War

The Pacific War, sometimes called the Asia–Pacific War, was the theater of World War II that was fought in the Pacific and Asia. It was fought over a vast area that included the Pacific Ocean and islands, the South West Pacific, South-East Asia, and in China.

The Newcastle Covering Force was an Australian militia force responsible for protecting strategically important Newcastle region and its approaches during World War II. Established on 8 April 1941, the formation's composition changed over the course of its existence, starting from a single infantry battalion support by a machine-gun unit and swelling to roughly brigade-size, with a brigade headquarters and three battalions – two infantry and one garrison – supported initially by a machine gun battalion that was later converted to a motor regiment. The unit was responsible for defending the important port and air bases in and around the town, part of Fortress Newcastle, against a feared Japanese invasion. Newcastle Covering Force was converted on 15 April 1942 to the 10th Division, a regular Australian Army unit, following a complete re-organisation of the higher command structures of the Australian Army.

1st Brigade (Australia) formation of the Australian Army

1st Brigade is a combined arms formation of the Australian Army. Formed in 1903 as a militia formation based in New South Wales, it was reconstituted as part of the Australian Imperial Force in 1914 for service during World War I, the brigade fought at Gallipoli and on the Western Front before being disbanded in mid-1919. In 1921, the 1st Brigade was re-raised as a unit of Australia's part-time military forces, based in New South Wales. During World War II the brigade undertook defensive duties before being disbanded. In 1948, it was re-raised as an integral part of the Australian Regular Army. Currently the brigade is based at Robertson Barracks in Darwin and at RAAF Base Edinburgh near Adelaide, South Australia. It is the first of the Australian Army brigades to be re-organised as a combat brigade under Plan Beersheba.

The Army's minimum need for replacement of wastage is 7,000 to 8,000 a month, against an estimated monthly intake in the coming year of 1,100 (youths turning 18). This does not enable existing army formations to be maintained. Eight infantry battalions have already been disbanded and absorbed into other units. This has involved the disbandment of the 10th Division and the absorption of its units into other formations. A further decrease in the number of battalions up to a total decrease of eleven battalions is contemplated. [5]

Plans to re-raise

Much later in the war, as Allied forces approached the Japanese home islands, planning began for a Commonwealth Corps, including an Australian Imperial Force (AIF) division, [6] to be the re-raised 10th Division. [7] The division was to be made up of experienced personnel from the existing divisions. The corps would have included British and Canadian divisions, and was to be part of a landing on Honshū in 1946. Regardless, the planned landing would have been dominated by US forces, and was known as Operation Coronet. [6]

The Commonwealth Corps was the name given to a proposed British Commonwealth army formation, which was scheduled to take part in the planned Allied invasion of Japan during 1945 and 1946. The corps was never formed, however, as the Japanese surrender obviated any need for it. Under the proposals the corps would have comprised Australian, British, Canadian and New Zealand forces.

Corps military unit size

Corps is a term used for several different kinds of organisation.

However, the introduction of nuclear weapons, and their use at Hiroshima and Nagasaki caused Japan to surrender before the invasion took place. [6] As a result, the 10th Division was never re-raised. Instead, the decision was made to raise the 34th Brigade for occupation duties in Japan as part of the British Commonwealth Occupation Force. This formation consisted of men drawn from the three remaining AIF divisions—the 6th, 7th and 9th Divisions. [8]

Nuclear weapon Explosive device that derives its destructive force from nuclear reactions

A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or from a combination of fission and fusion reactions. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to 20,000 tons of TNT (84 TJ). The first thermonuclear ("hydrogen") bomb test released energy approximately equal to 10 million tons of TNT (42 PJ). A thermonuclear weapon weighing little more than 2,400 pounds (1,100 kg) can release energy equal to more than 1.2 million tons of TNT (5.0 PJ). A nuclear device no larger than traditional bombs can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy.

Hiroshima Designated city in Chūgoku, Japan

Hiroshima is the capital of Hiroshima Prefecture and the largest city in the Chūgoku region of western Honshu, the largest island of Japan. Hiroshima gained city status on April 1, 1889. On April 1, 1980, Hiroshima became a designated city. As of August 2016, the city had an estimated population of 1,196,274. The gross domestic product (GDP) in Greater Hiroshima, Hiroshima Urban Employment Area, was US$61.3 billion as of 2010. Kazumi Matsui has been the city's mayor since April 2011.

34th Brigade (Australia)

The Australian 34th Brigade was an Australian Army brigade. The brigade was formed in late 1945 following the end of World War II as part of the Australian contribution to the British Commonwealth Occupation Force (BCOF) in Japan. In late 1948 it was renamed the 1st Brigade.

Subordinate units

13th Battalion (Australia)

The 13th Battalion was an infantry battalion of the Australian Army. Originally raised for the 1st Australian Imperial Force during the First World War, it was formed just six weeks after the start of the war. Along with the 14th, 15th and 16th Battalions which were recruited from New South Wales, it formed the 4th Brigade. The battalion saw service initially at Gallipoli before being transferred to France in 1916. For the next two years it fought in the trenches of the Western Front, earning numerous battle honours in the process.

41st Battalion, Royal New South Wales Regiment battalion of the Australian Army

The 41st Battalion, Royal New South Wales Regiment,, is an infantry battalion of the Australian Army. An Army Reserve unit, it is one of four battalions of the Royal New South Wales Regiment and is attached to the 5th Brigade, 2nd Division. It is based in northern New South Wales, with its headquarters in Lismore and depots in a number of locations including Tweed Heads, Grafton, Kempsey, Port Macquarie and Coffs Harbour. In its present form the battalion was raised in 1965, however, it can trace its lineage back to a couple of Scottish Rifles units formed in the 1800s in Byron Bay and Maclean. It also perpetuates the battle honours and traditions of the 41st Bn AIF, that served on the Western Front during World War I.

2nd Battalion (Australia) former infantry battalion of the Australian Army

The 2nd Battalion was an infantry battalion of the Australian Army. It was initially raised for service during the First World War as part the Australian Imperial Force and saw action at Gallipoli before being sent to the Western Front in mid-1916, where it spent the next two-and-a-half years taking part in the fighting in the trenches of France and Belgium. Following the conclusion of hostilities, the battalion was disbanded in early 1919 as part of the demobilisation process.
