Thomas Currie "Diver" Derrick, VC, DCM (20 March 1914 – 24 May 1945) was an Australian soldier and a recipient of the Victoria Cross, the highest decoration for gallantry "in the face of the enemy" awarded to members of the British and Commonwealth armed forces. In November 1943, during the Second World War, Derrick was awarded the Victoria Cross for his assault on a heavily defended Japanese position at Sattelberg, New Guinea. During the engagement, he scaled a cliff face while under heavy fire and silenced seven machine gun posts, before leading his platoon in a charge that destroyed a further three.

Born in the Adelaide suburb of Medindie, South Australia, Derrick left school at the age of fourteen and found work in a bakery. As the Great Depression grew worse he lost his job and moved to Berri, working on a fruit farm before marrying in 1939. In July 1941, Derrick enlisted in the Second Australian Imperial Force, joining the 2/48th Battalion. He was posted to the Middle East, where he took part in the siege of Tobruk, was recommended for the Military Medal and promoted to corporal. Later, at El Alamein, Derrick was awarded the Distinguished Conduct Medal for knocking out three German machine gun posts, destroying two tanks, and capturing one hundred prisoners.

Lieutenant Colonel Maurice Wilder-Neligan, CMG, DSO & Bar, DCM (born Maurice Neligan; 4 October 1882 – 10 January 1923), was an Australian soldier who commanded the South Australian-raised 10th Battalion during the latter stages of World War I. Raised and educated in the United Kingdom, he was briefly a soldier with the Royal Horse Artillery in London, after which he travelled to Australia where he worked in Queensland. He enlisted as a private in the Australian Imperial Force (AIF) on 20 August 1914 at Townsville, under the name Maurice Wilder, giving Auckland, New Zealand, as his place of birth. A sergeant in the 9th Battalion by the time of the Gallipoli landings of April 1915, he was awarded the Distinguished Conduct Medal, the second highest award for acts of gallantry by other ranks. He was quickly commissioned, reaching the rank of temporary captain before the end of the Gallipoli campaign. During his time at Gallipoli he was wounded once, and formally changed his name to Wilder-Neligan.

Arriving on the Western Front with the substantive rank of captain, he led a "most brilliant" raid on German trenches near Fleurbaix, and although severely wounded in the head, stuck to his command until the operation was successfully completed. For his actions he was appointed a Companion of the Distinguished Service Order (DSO), the second highest award for gallantry by officers. When he returned from hospital, he was promoted to major, and was in temporary command of his battalion during the Second Battle of Bullecourt in May 1917. In July, he was promoted to lieutenant colonel and appointed to command the 10th Battalion. He led that unit during the Battle of the Menin Road Ridge in September and was appointed a Companion of the Order of St Michael and St George in June 1918. Perhaps his greatest achievement was the capture of Merris in July, for which he was awarded a bar to his DSO, again for gallantry. He continued to skilfully lead his battalion throughout the Hundred Days Offensive and up to the Armistice of 11 November. During the war, in addition to decorations already mentioned, he was awarded the French Croix de guerre and was mentioned in despatches five times. (Full article...)

Paterson Clarence Hughes, DFC (19 September 1917 – 7 September 1940) was an Australian fighter ace of World War II. Serving with the Royal Air Force (RAF), he was credited with as many as seventeen aerial victories during the Battle of Britain, before being killed in action in September 1940. His tally made him the highest-scoring Australian of the battle, and among the three highest-scoring Australians of the war.

Born in Cooma, New South Wales, Hughes joined the Royal Australian Air Force as a cadet in 1936. After graduating as a pilot, he chose to take a commission with the RAF. In July 1937, he was assigned to No. 64 Squadron, which operated Hawker Demon and, later, Bristol Blenheim fighters. Posted to No. 234 Squadron following the outbreak of World War II, Hughes began flying Supermarine Spitfires as a flight commander. He shared in his unit's first aerial victory on 8 July 1940, and began scoring heavily against the Luftwaffe the following month. Known for his practice of attacking his targets at extremely close range, Hughes is generally thought to have died after his Spitfire was struck by flying debris from a German bomber that he had just shot down. He was posthumously awarded the Distinguished Flying Cross, and was buried in England. (Full article...)

Sir Michael Francis Addison Woodruff, FRS, FRSE, FRCS (3 April 1911 – 10 March 2001) was an English surgeon and scientist principally remembered for his research into organ transplantation. Though born in London, Woodruff spent his youth in Australia, where he earned degrees in electrical engineering and medicine. Having completed his studies shortly after the outbreak of World War II, he joined the Australian Army Medical Corps, but was soon captured by Japanese forces and imprisoned in the Changi Prison Camp. While there, he devised an ingenious method of extracting nutrients from agricultural wastes to prevent malnutrition among his fellow POWs.

At the conclusion of the war, Woodruff returned to England and began a long career as an academic surgeon, mixing clinical work and research. Woodruff principally studied transplant rejection and immunosuppression. His work in these areas of transplantation biology led Woodruff to perform the first kidney transplant in the United Kingdom, on 30 October 1960. For this and his other scientific contributions, Woodruff was elected a Fellow of the Royal Society in 1968 and made a Knight Bachelor in 1969. Although retiring from surgical work in 1976, he remained an active figure in the scientific community, researching cancer and serving on the boards of various medical and scientific organisations.

Brigadier Sir Neil Hamilton Fairley, KBE, CStJ, FRACP, FRCP, FRCPE, FRS (15 July 1891 – 19 April 1966) was an Australian physician, medical scientist, and army officer who was instrumental in saving thousands of Allied lives from malaria and other diseases.

A graduate of the University of Melbourne, Fairley joined the Australian Army Medical Corps in 1915. He investigated an epidemic of meningitis that was occurring in Army camps in Australia. While with the 14th General Hospital in Cairo, he investigated schistosomiasis (then known as bilharzia) and developed tests and treatments for the disease. In the inter-war period he became renowned as an expert on tropical medicine. (Full article...)

Air Marshal Sir John Patrick Joseph McCauley, KBE, CB (18 March 1899 – 3 February 1989) was a senior commander in the Royal Australian Air Force (RAAF). He served as Chief of the Air Staff from 1954 to 1957. A Duntroon graduate, McCauley spent four years in the Australian Military Forces before transferring to the RAAF in 1924. He was Director of Training from 1936 to 1938, and commanded engineering and flying training schools for the first eighteen months of World War II. Having been promoted to group captain in 1940, he was posted to Singapore in June 1941 to take charge of all RAAF units defending the area. He earned praise for his efforts in attacking invading Japanese forces before the fall of Singapore, and for his dedication in evacuating his men. After serving as Deputy Chief of the Air Staff in 1942–44, he was appointed to a senior operational role with the Royal Air Force's 2nd Tactical Air Force in Europe, where he saw out the rest of the war.

Following the end of hostilities, McCauley again became Deputy Chief of the Air Staff. In 1947 he was promoted to air vice marshal and appointed Chief of Staff at British Commonwealth Occupation Force Headquarters in Japan. Returning to Australia in June 1949, he served as the last Air Officer Commanding (AOC) Eastern Area and the inaugural AOC Home Command (now Air Command). Raised to air marshal, he took up the position of Chief of the Air Staff in January 1954, and was knighted a year later. During his tenure in the RAAF's senior role, McCauley focused on potential deployments to Southeast Asia—particularly Vietnam—and threats from the north, commencing redevelopment of RAAF Base Darwin and recommending purchase of a light supersonic bomber to replace the Air Force's English Electric Canberra. After retiring from military life in March 1957, he chaired community and welfare organisations, serving as Federal President of the Air Force Association for ten years. He died in Sydney in 1989, aged 89. (Full article...)

Air Vice Marshal Ian Dougald McLachlan, CB, CBE, DFC (23 July 1911 – 14 July 1991) was a senior commander in the Royal Australian Air Force (RAAF). Born in Melbourne, he was a cadet at the Royal Military College, Duntroon, before joining the Air Force in December 1930. After serving in instructional and general flying roles, he took command of No. 3 Squadron in December 1939, leading it into action in the Middle East less than a year later. Awarded the Distinguished Flying Cross, he returned to Australia in 1942 to command air bases in Canberra and Melbourne. The following year he was posted to the South West Pacific, where he led successively Nos. 71 and 73 Wings. Having been promoted to group captain, he took charge of Southern Area Command in 1944, and No. 81 Wing in the Dutch East Indies the following year.

Raised to acting air commodore in 1946, McLachlan served as senior air staff officer for the British Commonwealth Air Group in Japan until 1948. After leading North-Eastern Area Command in 1951–53, he was appointed a Commander of the Order of the British Empire and posted to Britain, where he attended the Imperial Defence College. Promoted air vice marshal, he returned to Australia in 1957 as Air Officer Commanding Training Command; in this role he carried out two major reviews focussing on the RAAF's educational and command systems. He was Deputy Chief of the Air Staff from 1959 to 1961, and then Head of the Australian Joint Services Staff in Washington, D.C., until 1963. Appointed a Companion of the Order of the Bath in 1966, McLachlan's final post before retiring in 1968 was as Air Member for Supply and Equipment. He was a consultant to Northrop after leaving the RAAF, and lived in Darling Point, Sydney, until his death in 1991. (Full article...)

No. 1 Flying Training School (No. 1 FTS) is a school of the Royal Australian Air Force (RAAF). It is one of the Air Force's original units, dating back to the service's formation in 1921, when it was established at RAAF Point Cook, Victoria. By the early 1930s, the school comprised training, fighter, and seaplane components. It was re-formed several times in the ensuing years, initially as No. 1 Service Flying Training School (No. 1 SFTS) in 1940, under the wartime Empire Air Training Scheme. After graduating nearly 3,000 pilots, No. 1 SFTS was disbanded in late 1944, when there was no further requirement to train Australian aircrew for service in Europe.

The school was re-established in 1946 as No. 1 FTS at RAAF Station Uranquinty, New South Wales, and transferred to Point Cook the following year. Under a restructure of flying training to cope with the demands of the Korean War and Malayan Emergency, No. 1 FTS was re-formed in 1952 as No. 1 Applied Flying Training School (No. 1 AFTS); it moved to RAAF Base Pearce, Western Australia, in 1958. For much of this period the school was also responsible for training the RAAF's air traffic controllers. Its pilot trainees included Army, Navy, and foreign students as well as RAAF personnel. The RAAF's reorganisation of aircrew training in the early 1950s had led to the formation at Uranquinty of No. 1 Basic Flying Training School (No. 1 BFTS), which transferred to Point Cook in 1958. In 1969, No. 1 AFTS was re-formed as No. 2 Flying Training School and No. 1 BFTS was re-formed as No. 1 FTS. Rationalisation of RAAF flying training resulted in the disbandment of No. 1 FTS in 1993.

Air Marshal Sir George Jones, KBE, CB, DFC (18 October 1896 – 24 August 1992) was a senior commander in the Royal Australian Air Force (RAAF). He rose from private soldier in World War I to air marshal in 1948, and served as Chief of the Air Staff from 1942 to 1952, the longest continuous tenure of any RAAF chief. Jones was a surprise appointee to the Air Force's top role, and his achievements in the position were coloured by a divisive relationship during World War II with his nominal subordinate, the head of RAAF Command, Air Vice-Marshal William Bostock.

During World War I, Jones saw action as an infantryman in the Gallipoli Campaign of 1915, transferring to the Australian Flying Corps a year later. Originally a mechanic, he undertook flying training in 1917 and was posted to a fighter squadron in France. He achieved seven victories to become an ace, and was awarded the Distinguished Flying Cross. After a short spell in civilian life following World War I, he joined the newly formed RAAF in 1921, and rose steadily through training and personnel commands prior to World War II.

The Battle of Cape Esperance, also known as the Second Battle of Savo Island and in Japanese sources as the Sea Battle of Savo Island (サボ島沖海戦), took place on 11–12 October 1942, in the Pacific campaign of World War II between the Imperial Japanese Navy and United States Navy. The naval battle was the second of four major surface engagements during the Guadalcanal campaign and took place at the entrance to the strait between Savo Island and Guadalcanal in the Solomon Islands. Cape Esperance () is the northernmost point on Guadalcanal, and the battle took its name from this point.

On the night of 11 October, Japanese naval forces in the Solomon Islands area—under the command of Vice Admiral Gunichi Mikawa—sent a major supply and reinforcement convoy to their forces on Guadalcanal. The convoy consisted of two seaplane tenders and six destroyers and was commanded by Rear Admiral Takatsugu Jojima. At the same time but in a separate operation, three heavy cruisers and two destroyers—under the command of Rear Admiral Aritomo Gotō—were to bombard the Allied airfield on Guadalcanal (called Henderson Field by the Allies) with the object of destroying Allied aircraft and the airfield's facilities.

The Hobart class is a ship class of three air warfare destroyers (AWDs) built for the Royal Australian Navy (RAN). Planning for ships to replace the Adelaide-class frigates and restore the capability last exhibited by the Perth-class destroyers began by 2000, initially under acquisition project SEA 1400, which was re-designated SEA 4000. Although the designation "Air Warfare Destroyer" is used to describe ships dedicated to the defence of a naval force (plus assets ashore) from aircraft and missile attack, the planned Australian destroyers are expected to also operate in anti-surface, anti-submarine, and naval gunfire support roles.

Planning for the Australian Air Warfare Destroyer (as the class was known until 2006) continued through the mid-2000s, with the selection of the Aegis combat system as the intended combat system and ASC Pty Ltd (ASC) as the primary shipbuilder in 2005. In late 2005, the AWD Alliance was formed as a consortium of the Defence Materiel Organisation (DMO), ASC, and Raytheon. Between 2005 and 2007, Gibbs & Cox's Evolved Arleigh Burke-class destroyer concept and Navantia's Álvaro de Bazán-class frigate competed for selection as the AWD design. Although the Arleigh Burke design was larger and more capable, the Álvaro de Bazán design was selected in June 2007 as it was an existing design and would be cheaper, quicker, and less risky to build.

Major General Philip Michael Jeffery, AC, CVO, MC (12 December 1937 – 18 December 2020) was a senior Australian Army officer and vice-regal representative. He was the 28th governor of Western Australia from 1993 to 2000, and the 24th governor-general of Australia, serving from 2003 to 2008.

From Perth, Western Australia, Jeffery graduated from the Royal Military College, Duntroon, and served in the Malayan Emergency and the Vietnam War, being awarded the Military Cross during the latter conflict. (Full article...)

The Australian frontier wars were the violent conflicts between Indigenous Australians (including both Aboriginal Australians and Torres Strait Islanders) and primarily British settlers during the colonial period of Australia.

The first conflict took place several months after the landing of the First Fleet in January 1788, and the last frontier conflicts occurred in the early 20th century following the federation of the Australian colonies in 1901, with some occurring as late as 1934. Conflicts occurred in a number of locations across Australia. (Full article...)

Vice Admiral Sir John Augustine Collins, KBE, CB (7 January 1899 – 3 September 1989) was a Royal Australian Navy (RAN) officer who served in both World Wars, and who eventually rose to become a vice admiral and Chief of Naval Staff. Collins was one of the first graduates of the Royal Australian Naval College to attain flag rank. During the Second World War, he commanded the cruiser HMAS Sydney in the Mediterranean campaign. He led the Australian Naval Squadron in the Pacific theatre and was wounded in the first recorded kamikaze attack, in 1944. (Full article...)

The Invasion of Lingayen Gulf (Filipino: Paglusob sa Golpo ng Lingayen), 6–9 January 1945, was an Allied amphibious operation in the Philippines during World War II. In the early morning of 6 January 1945, a large Allied force commanded by Admiral Jesse B. Oldendorf began approaching the shores of Lingayen from Lingayen Gulf, on the island of Luzon. U.S. Navy and Royal Australian Navy warships began bombarding suspected Japanese positions along the coast of Lingayen from their position in Lingayen Gulf for three days. On "S-Day", 9 January, the U.S. 6th Army landed on a roughly 25 mi (40 km) beachhead at the base of the Gulf between the towns of Lingayen and San Fabian. (Full article...)

Until Australia became a Federation in 1901, each of the six colonies were responsible for their own defence. From 1788 until 1870 this was done with British regular forces. In all, 24 British infantry regiments served in the Australian colonies. Each of the Australian colonies gained responsible government between 1855 and 1890, and while the Colonial Office in London retained control of some affairs, and the colonies were still firmly within the British Empire, the Governors of the Australian colonies were required to raise their own colonial militia. To do this, the colonial Governors had the authority from the British crown to raise military and naval forces. Initially these were militias in support of British regulars, but British military support for the colonies ended in 1870, and the colonies assumed their own defence. The separate colonies maintained control over their respective militia forces and navies until 1 March 1901, when the colonial forces were all amalgamated into the Commonwealth Forces following the creation of the Commonwealth of Australia. Colonial forces, including home raised units, saw action in many of the conflicts of the British Empire during the 19th century. Members from British regiments stationed in Australia saw action in India, Afghanistan, the New Zealand Wars, the Sudan conflict, and the Boer War in South Africa.

Despite an undeserved reputation of colonial inferiority, many of the locally raised units were highly organised, disciplined, professional, and well trained. For most of the time from settlement until Federation, military defences in Australia revolved around static defence by combined infantry and artillery, based on garrisoned coastal forts; however, in the 1890s improved railway communications between all of the eastern mainland colonies (Queensland, New South Wales, Victoria, and South Australia), led Major General Bevan Edwards, who had recently completed a survey of colonial military forces, to state his belief that the colonies could be defended by the rapid mobilisation of standard brigades. He called for a restructure of colonial defences, and defensive agreements to be made between the colonies. He also called for professional units to replace all of the volunteer forces.

Operation Downfall was the proposed Allied plan for the invasion of the Japanese home islands near the end of World War II. The planned operation was canceled when Japan surrendered following the atomic bombings of Hiroshima and Nagasaki, the Soviet declaration of war, and the 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. In early 1946 would come Operation Coronet, the planned invasion of the Kantō Plain, near Tokyo, on the main 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, surpassing D-Day.

Japan's geography made this invasion plan obvious to the Japanese as well; they were able to accurately predict the Allied invasion plans and thus adjust their defensive plan, Operation Ketsugō (ja), accordingly. The Japanese planned an all-out defense of Kyūshū, with little left in reserve for any subsequent defense operations. Casualty predictions varied widely, but were extremely high. Depending on the degree to which Japanese civilians would have resisted the invasion, estimates ran up into the millions for Allied casualties. (Full article...)

The New Guinea campaign of the Pacific War lasted from January 1942 until the end of the war in August 1945. During the initial phase in early 1942, the Empire of Japan invaded the Territory of New Guinea on 23 January and Territory of Papua on 21 July and overran western New Guinea (part of the Netherlands East Indies) beginning on 29 March. During the second phase, lasting from late 1942 until the Japanese surrender, the Allies—consisting primarily of Australian forces—cleared the Japanese first from Papua, then New Guinea, and finally from the Dutch colony.

The campaign resulted in a crushing defeat and heavy losses for the Empire of Japan. As in most Pacific War campaigns, disease and starvation claimed more Japanese lives than enemy action. Most Japanese troops never even came into contact with Allied forces and were instead simply cut off and subjected to an effective blockade by Allied naval forces. Garrisons were effectively besieged and denied shipments of food and medical supplies, and as a result some claim that 97% of Japanese deaths in this campaign were from non-combat causes. According to John Laffin, the campaign "was arguably the most arduous fought by any Allied troops during World War II". (Full article...)

The Leeuwin class is a two-ship class of hydrographic survey vessels operated by the Royal Australian Navy (RAN). Leeuwin and Melville were ordered from NQEA Australia in 1996, and were commissioned in 2000. The ships are capable of charting waters up to 6,000 metres (20,000 ft) deep, carry three Fantome-class survey boats, and could operate an AS 350B Squirrel helicopter. In addition to surveying duties, since 2001 both vessels have been used to supplement the RAN patrol force. Leeuwin and Melville are based at HMAS Cairns, and are active as of 2023.

Operation Astute was an Australian-led military deployment to East Timor to quell unrest and return stability in the 2006 East Timor crisis. It was headed by Brigadier Bill Sowry, and commenced on 25 May 2006 under the command of Brigadier Michael Slater. The operation was established at the request of East Timor's government, and continued under an understanding reached between Australia, East Timor, and the United Nations, with the United Nations Integrated Mission in East Timor supporting and helping to develop East Timor's police force. Other countries deploying soldiers to East Timor include Malaysia, New Zealand and East Timor's former colonial power Portugal, operating under independent command. (Full article...)

No. 71 Wing was a Royal Australian Air Force (RAAF) wing of World War II. It was formed in February 1943 at Milne Bay, Papua New Guinea, as part of No. 9 Operational Group. The wing initially comprised two squadrons of P-40 Kittyhawks, one of Lockheed Hudsons, and one of Bristol Beauforts. The wing's mainstay soon became the Beaufort, which eventually equipped five squadrons attached to the formation. No. 71 Wing took part in the New Guinea campaign under the auspices of No. 9 Group, before transferring to No. 10 Operational Group for the Western New Guinea campaign during 1944. It then returned to the control of Northern Command (formerly No. 9 Group) to support Australian ground forces in the Aitape–Wewak campaign, and completed its final combat mission only hours before the Japanese surrender in August 1945. No. 71 Wing remained in New Guinea following the war and was disbanded in January 1946. (Full article...)

Air Commodore Peter Frank Raw, DSO, DFC, AFC (5 June 1922 – 14 July 1988) was a senior officer and pilot in the Royal Australian Air Force (RAAF). He saw combat in a heavy bomber unit in the European theatre during the later stages of World War II and as a senior officer in the Vietnam War, and served in many flying, training and administrative roles.

Raw joined the RAAF in 1941, and served as a flight instructor, bomber pilot and the commander of a communications unit during World War II. After the war he became a specialist navigator. He was appointed commanding officer of the bomber-equipped No. 2 Squadron in January 1953, but temporarily left this position for part of the year to participate in the 1953 London to Christchurch air race, in which he placed second. He returned to lead No. 2 Squadron at the end of 1953 and held the position until 1955. (Full article...)

No. 79 Wing was a Royal Australian Air Force (RAAF) wing of World War II. It was formed in December 1943 at Batchelor, Northern Territory, as part of North-Western Area Command. Led by Group Captain Charles Eaton, the wing comprised four squadrons on its establishment, flying Beaufort and B-25 Mitchell bombers and Beaufighter heavy fighters. No. 79 Wing took part in the New Guinea and North-Western Area Campaigns during 1944–45, eventually transferring to Balikpapan in the Dutch East Indies as the Allies advanced northward. By the end of the Pacific War, the wing was attached to the Australian First Tactical Air Force and was made up of Nos. 2 and 18 (Netherlands East Indies) Squadrons, both flying Mitchells. The latter transferred to the Netherlands Air Force in late 1945, while the former returned to Australia where it disbanded the following year. No. 79 Headquarters itself disbanded in October 1945, soon after the end of hostilities. (Full article...)

John "Barney" Hines (1878–1958) was a British-born Australian soldier of World War I, known for his prowess at taking items from German soldiers. Hines was the subject of a famous photo taken by Frank Hurley that depicted him surrounded by German military equipment and money he had looted during the Battle of Polygon Wood in September 1917. This image is among the best-known Australian photographs of the war.

Born in Liverpool, England, in 1878, Hines served in the British Army and Royal Navy, and worked in several occupations. He arrived in Australia in 1915 and volunteered for the Australian Imperial Force in August 1915. Although discharged due to poor health in early 1916, he rejoined in August that year and served on the Western Front from March 1917 to mid-1918, when he was discharged again for health reasons. During his period in France he proved to be an aggressive soldier, and gained fame for the collection of items that he amassed, but was undisciplined when not in combat and frequently punished. After the war, Hines lived in poverty on the outskirts of Sydney until his death in 1958. (Full article...)

The Battle of Gang Toi (8 November 1965) was fought during the Vietnam War between Australian troops and the Viet Cong. The battle was one of the first engagements between the two forces during the war and occurred when A Company, 1st Battalion, Royal Australian Regiment (1 RAR) struck a Viet Cong bunker system defended by Company 238 in the Gang Toi Hills, in northern Bien Hoa Province. It occurred during a major joint US-Australian operation codenamed Operation Hump, involving the US 173rd Airborne Brigade, to which 1 RAR was attached. During the latter part of the operation an Australian rifle company clashed with an entrenched company-sized Viet Cong force in well-prepared defensive positions. Meanwhile, an American paratroop battalion was also heavily engaged in fighting on the other side of the Song Dong Nai.

The Australians were unable to concentrate sufficient combat power to launch an assault on the position and consequently they were forced to withdraw after a fierce engagement during which both sides suffered a number of casualties, reluctantly leaving behind two men who had been shot and could not be recovered due to heavy machine-gun and rifle fire. Although they were most likely dead, a battalion-attack to recover the missing soldiers was planned by the Australians for the next day, but this was cancelled by the American brigade commander due to rising casualties and the need to utilise all available helicopters for casualty evacuation. The bodies of the two missing Australian soldiers were subsequently recovered more than 40 years later, and were finally returned to Australia for burial. (Full article...)

The Battle of Lone Pine (also known as the Battle of Kanlı Sırt) was fought between Australian and New Zealand Army Corps (ANZAC) and Ottoman Empire forces during the Gallipoli Campaign of the First World War, between 6 and 10 August 1915. The battle was part of a diversionary attack to draw Ottoman attention away from the main assaults being conducted by British, Indian and New Zealand troops around Sari Bair, Chunuk Bair and Hill 971, which became known as the August Offensive.

At Lone Pine, the assaulting force, initially consisting of the Australian 1st Brigade, managed to capture the main trench line from the two Ottoman battalions that were defending the position in the first few hours of the fighting on 6 August. Over the next three days, the fighting continued as the Ottomans brought up reinforcements and launched numerous counterattacks in an attempt to recapture the ground they had lost. As the counterattacks intensified the ANZACs brought up two fresh battalions to reinforce their newly gained line. Finally, on 9 August the Ottomans called off any further attempts and by 10 August offensive action ceased, leaving the Allies in control of the position. Nevertheless, despite the Australian victory, the wider August Offensive of which the attack had been a part failed and a situation of stalemate developed around Lone Pine which lasted until the end of the campaign in December 1915 when Allied troops were evacuated from the peninsula.

The Battle of Pakchon (5 November 1950), also known as the Battle of Bochuan (Chinese: 博川战斗; pinyin: Bó Chuān Zhàn Dòu), took place ten days after the start of the Chinese First Phase Offensive, following the entry of the Chinese People's Volunteer Army (PVA) into the Korean War. The offensive reversed the United Nations Command (UN) advance towards the Yalu River which had occurred after their intervention in the wake of the North Korean invasion of South Korea at the start of the war. The battle was fought between British and Australian forces from the 27th British Commonwealth Brigade with American armour and artillery in support, and the PVA 117th Division of the 39th Army, around the village of Pakchon on the Taeryong River. After capturing Chongju on 30 October the British and Australians had been ordered to pull back to Pakchon in an attempt to consolidate the western flank of the US Eighth Army. Meanwhile, immediately following their success at Unsan against the Americans, the PVA 117th Division had attacked southward, intending to cut off the UN forces as they withdrew in the face of the unexpected PVA assault. To halt the PVA advance, the 27th British Commonwealth Brigade was ordered to defend the lower crossings of the Taeryong and Chongchon rivers as part of a rearguard, in conjunction with the US 24th Infantry Division further upstream on the right.

During the night of 4/5 November, the PVA and Korean People's Army (KPA) mounted a full-scale assault on the US 24th Infantry Division, pushing back an American infantry regiment nearly 2 kilometres (1.2 mi). The PVA/KPA force subsequently turned west, advancing between the Taeryong and Chongchon rivers and threatening the rear of the 27th British Commonwealth Brigade by cutting the Pakchon–Sinanju road. The following day they attacked an American artillery battery which was guarding a vital concrete bridge near Kujin. The British and Australians then successfully counter-attacked the PVA forces occupying a number of nearby ridgelines during the day but were in turn counter-attacked before being pushed off the high ground during the night. In their first battle with the PVA, the 3rd Battalion, Royal Australian Regiment (3 RAR) captured a well defended hill with only limited offensive support, and held it in the face of heavy counter-attacks before confused command decisions resulted in a disorganised night withdrawal while still in contact. The withdrawal threatened to open the 27th British Commonwealth Brigade's left flank and the Australians were ordered to immediately reposition on the ridge, yet ultimately it was too late to regain the feature in darkness. However, following heavy fighting the pressure on the Australians unexpectedly ceased after midnight, and parties of PVA were observed beginning to withdraw. By early morning the PVA attack had been checked and 3 RAR had redeployed to new positions in the paddy fields around the railway crossing north of Maenjung-dong. (Full article...)

The Borneo campaign or Second Battle of Borneo was the last major Allied campaign in the South West Pacific Area during World War II to liberate Japanese-held British Borneo and Dutch Borneo. Designated collectively as Operation Oboe, a series of amphibious assaults between 1 May and 21 July 1945 were conducted by the Australian I Corps, under Lieutenant-General Leslie Morshead, against Imperial Japanese forces who had been occupying the island since late 1941 – early 1942. The main Japanese formation on the island was the Thirty-Seventh Army under Lieutenant-General Masao Baba, while the naval garrison was commanded by Vice-Admiral Michiaki Kamada. The Australian ground forces were supported by US and other Allied air and naval forces, with the US providing the bulk of the shipping and logistic support necessary to conduct the operation. The campaign was initially planned to involve six stages, but eventually landings were undertaken at four locations: Tarakan, Labuan, North Borneo and Balikpapan. Guerilla operations were also carried out by Dayak tribesmen and small numbers of Allied personnel in the interior of the island. While major combat operations were concluded by mid-July, localised fighting continued throughout Borneo until the end of the war in August. Initially intended to secure vital airfields and port facilities to support future operations, preparatory bombardment resulted in heavy damage to the island's infrastructure, including its oil production facilities. As a result, the strategic benefits the Allies gained from the campaign were negligible. (Full article...)

The 2/48th Battalion was an infantry battalion of the Australian Army which served during the Second World War. Raised in Adelaide in South Australia in August 1940, the battalion formed part of the 26th Brigade and was initially assigned to the 7th Division, although it was later transferred to the 9th Division in 1941 when it was deployed to the Middle East. While there, it saw action during the siege of Tobruk and the First and Second Battles of El Alamein before being returned to Australia to take part in the fighting in New Guinea following Japan's entry into the war.

During the campaign in New Guinea, the battalion took part in the advance on Lae during the Salamaua–Lae campaign and the fighting around Finschhafen and Sattelberg, during the Huon Peninsula campaign. Following this it was withdrawn to Australia, where it remained for over a year. In mid-1945, the 2/48th Battalion took part in the landing on Tarakan, which was its final involvement in the war. It was disbanded in October 1945 and is considered to be Australia's most highly decorated unit of the war, with four members receiving the Victoria Cross, the nation's highest decoration for gallantry, while over 90 other decorations were also made to its members.

The 1st Armoured Brigade was a formation of the Australian Army during World War II. The brigade was formed in July 1941, at Greta, New South Wales from volunteers for the Second Australian Imperial Force and was assigned to the 1st Armoured Division. Raised initially for service in the Middle East, following Japan's entry into the war, the brigade was assigned to the defence of Australia in case of an invasion. After garrison duties in New South Wales and Western Australia, it was disbanded in November 1944 without seeing active service, although some of its former units saw action later with other formations.

It was re-raised in the postwar period, serving in the Citizens Military Force between 1948 and 1957. During this period, the brigade was based in New South Wales and formed part of Eastern Command. The brigade's headquarters was broken up when the Australian Army determined that there was no need for large-scale armoured formations as the focus shifted to jungle operations and close infantry-armoured cooperation. Its constituent units were subsequently dispersed to other formations. (Full article...)
