Brigadier Arnold William Potts, was an Australian grazier and army officer who served in the First World War and led the 21st Brigade of the Second Australian Imperial Force during its defence of the Kokoda Trail during the Second World War. He had a distinguished career, however, his place in history has largely been unacknowledged due to his dismissal by General Sir Thomas Blamey, at the very point when Potts had fought the Japanese to exhaustion. His fighting withdrawal over the Kokoda Trail has been called "one of the most critical triumphs in Australian military history and one that an apathetic nation has still to honour". Many contemporaries as well as Potts' official biographer regard this sacking as one of the most disgraceful actions of Blamey's military career. Following his dismissal, Potts went on to command the 23rd Brigade during the Bougainville campaign where he earned a reputation for setting high standards. He retired from the military following the end of the war and unsuccessfully pursued a career in politics. He died in 1968, aged 71.
Maroubra Force was the name given to the ad hoc Australian infantry force that defended Port Moresby, Papua New Guinea from the Japanese, and was involved in the Kokoda Track Campaign of the Pacific War, World War II. The force was established by the Allies under the codename "Maroubra", referring to the troops in the forward area, it was one of many units forming the body of the New Guinea Force, the main Allied army formation in the South West Pacific Area during 1942.
The Kokoda Track campaign or Kokoda Trail campaign was part of the Pacific War of World War II. The campaign consisted of a series of battles fought between July and November 1942 in what was then the Australian Territory of Papua. It was primarily a land battle, between the Japanese South Seas Detachment under Major General Tomitarō Horii and Australian and Papuan land forces under command of New Guinea Force. The Japanese objective was to seize Port Moresby by an overland advance from the north coast, following the Kokoda Track over the mountains of the Owen Stanley Range, as part of a strategy to isolate Australia from the United States.
The 39th Battalion was an infantry unit of the Australian Army. It was originally raised in February 1916 for service during World War I as part of First Australian Imperial Force, with personnel being drawn mainly from the state of Victoria. Making up part of the 10th Brigade, it was attached to the 3rd Division and served on the Western Front in France and Belgium before being disbanded in March 1919. Following the re-organisation of the Australian Army in 1921, the battalion was raised again in Victoria as a unit of the Citizens Force, becoming known as the "Hawthorn–Kew Regiment". In 1937, it was amalgamated with the 37th Battalion to become the 37th/39th Battalion. Later, in August 1939 it was delinked with the 37th and amalgamated with the 24th Battalion to form the 24th/39th Battalion, before being raised again as a single unit in October 1941.
The 3rd Battalion was an infantry battalion of the Australian Army. Originally raised as part of the First Australian Imperial Force for service during World War I, the battalion formed part of the 1st Brigade, attached to the 1st Division. It was formed shortly after the war broke out and was among the first Australian units to be sent overseas, arriving in Egypt in December 1914. In April 1915 the battalion participated in the Landing at Anzac Cove, coming ashore in the second and third waves. In December 1915 the 3rd Battalion was evacuated from the Gallipoli peninsula and withdrawn to Egypt again, where it took part in the defence of the Suez Canal before being sent to France to fight on the Western Front in March 1916. For the next two and a half years the unit would serve in the trenches in France and Belgium and would take part in many of the major battles fought during that time. In May 1919, following the end of the war, the battalion was disbanded and its personnel repatriated back to Australia.
The 25th Brigade was a brigade-sized infantry unit of the Australian Army that served during the Second World War. Raised in July 1940 and consisting of three infantry battalions, the 25th Brigade initially served in the United Kingdom, where it formed part of the garrison tasked with defending against a possible German invasion. In 1941, the brigade was redeployed to the Middle East where it took part in the Syria–Lebanon campaign fighting several actions around Merdjayoun and Jezzine.
The 30th Brigade was a brigade-sized infantry unit of the Australian Army. Formed in December 1941, as part of the Militia, the unit was raised for service during the Second World War. Established in response to Japan's entry into the war, the brigade's subordinate units were established in several Australian states. Some of these had already been dispatched to New Guinea before the brigade's headquarters was established, although the majority arrived there in early 1942. Following their arrival, the brigade initially provided garrison troops to Port Moresby before later taking part in the fighting along the Kokoda Track during which elements took part in delaying actions around Kokoda and Isurava, before being relieved by units of the Second Australian Imperial Force. After the campaign began to turn in favour of the Australians, the Japanese withdrew north towards their beachheads around Buna and Gona, and elements of the brigade were recommitted to the fighting. In early 1943, the 30th Brigade was withdrawn back to Australia and was disbanded in July 1943, with its personnel being redistributed to other formations.
The 21st Brigade was a brigade-sized infantry unit of the Australian Army. It was briefly raised in 1912 as a Militia formation providing training as part of the compulsory training scheme. Later, it was re-formed in April 1940 as part of the Second Australian Imperial Force, the unit was raised for service during World War II. As part of the 7th Division the brigade's constituent units were raised from volunteers from several Australian states. After rudimentary training in Australia, the brigade deployed for the Middle East in October 1940. Defensive duties were mounted along the Libyan border in early 1941, before the brigade was committed to the Syria-Lebanon campaign, fighting against Vichy French forces. In early 1942, following Japan's entry into the war, the brigade returned to Australia. After a period of defensive duties in Australia, it was deployed to New Guinea and subsequently played a key role in the Kokoda Track campaign, delaying the Japanese advance towards Port Moresby and then joining the pursuit as the Japanese withdrew towards Buna–Gona. In 1943–1944, the brigade took part in the capture of Lae and the Ramu Valley–Finisterre Range campaign. Its final campaign of the war, came in the final months when it took part in the Balikpapan landings. It was disbanded in 1946.
The Invasion of Buna–Gona, called Operation RI by the Japanese, was a military operation by Imperial Japanese forces to occupy the Buna–Gona area in the Territory of Papua during the Pacific campaign of the Second World War. The initial landings and advance on Kokoda occurred between 21 and 27 July 1942. The Japanese invaded and occupied the location in preparation for an overland attack on Port Moresby along the Kokoda Track. The landing marked the start of the Kokoda Track campaign. The landings were not directly opposed by land forces but were engaged by elements of Maroubra Force as they advanced on Kokoda. This initially included B Company of the 39th Battalion, patrols of the Papuan Infantry Battalion (PIB) operating in the area and a small number of the Australian New Guinea Administrative Unit (ANGAU) that became attached to the force. The Australians were initially repulsed near Oivi but subsequently regrouped to defend Kokoda in an initial battle there from 28–29 July.
The 2/14th Battalion was an infantry battalion of the Australian Army that served during World War II. Part of the 21st Brigade, 7th Division, the battalion was raised from Second Australian Imperial Force volunteers drawn mainly from the state of Victoria. After completing training in Australia in 1940, the battalion deployed to the Middle East where it was stationed in Egypt and Palestine before it saw action against the Vichy French in Syria in June and July 1941, in a short lived campaign. Garrison duties in Lebanon followed before the battalion was withdrawn to Australia in early 1942 as Australian forces were concentrated in the Pacific to respond to the threat posed by Japan's entry into the war.
The 2/33rd Battalion was an infantry battalion of the Australian Army during the Second World War. It was formed as part of the Second Australian Imperial Force in the United Kingdom in June 1940 as the "72nd Battalion" to create the 25th Brigade, which eventually became part of the 7th Division. After the threat of invasion had passed, the battalion was transferred to the Middle East in early 1941, and after a period of garrison duty in the Western Desert, the battalion fought against the Vichy French in the invasion of Syria and Lebanon.
The 2/27th Battalion was an infantry battalion of the Australian Army during World War II. Raised in May 1940 as part of the 7th Division from volunteers from the state of South Australia, the battalion was assigned to the 21st Brigade. After completing training in Australia, the 2/27th deployed to the Middle East in November 1940, and in early 1941 undertook defensive duties in the Western Desert. The battalion's first combat experience came against the Vichy French during the short Syria–Lebanon campaign during which it fought major engagements around Sidon and Damour. At the conclusion of the fighting in Syria, the battalion remained in the area as part of the Allied occupation force until early 1942 when it was returned to Australia to fight against the Japanese.
The Battle of Isurava took place over the period 26 to 31 August 1942. Forming part of the Kokoda Track campaign of the Second World War, the battle involved military forces from Australia, supported by the United States, fighting against Japanese troops from Major General Tomitaro Horii's South Seas Detachment who had landed around Buna and Gona in Papua mid-July 1942, with the intent of capturing Port Moresby to the south via the overland route.
The Battle of Buna–Gona was part of the New Guinea campaign in the Pacific Theatre during World War II. It followed the conclusion of the Kokoda Track campaign and lasted from 16 November 1942 until 22 January 1943. The battle was fought by Australian and United States forces against the Japanese beachheads at Buna, Sanananda and Gona. From these, the Japanese had launched an overland attack on Port Moresby. In light of developments in the Solomon Islands campaign, Japanese forces approaching Port Moresby were ordered to withdraw to and secure these bases on the northern coast. Australian forces maintained contact as the Japanese conducted a well-ordered rearguard action. The Allied objective was to eject the Japanese forces from these positions and deny them their further use. The Japanese forces were skillful, well prepared and resolute in their defence. They had developed a strong network of well-concealed defences.
The Battle of Mission Ridge – Brigade Hill took place between 6 and 9 September 1942, during the Kokoda Track campaign of the Second World War. Involving forces from Australia, the United States, and Japan, the fighting centred on a high feature south of the village of Efogi on the Kokoda Track.
The Battle of Oivi–Gorari was the final major battle of the Kokoda Track campaign before the Battle of Buna–Gona. Following the capture of Kokoda by Australian forces on 2 November, the Allies began flying in fresh supplies of ammunition and food to ease the supply problems that had slowed their advance north after the climactic battle around Ioribaiwa, which coupled with reverses elsewhere, had stopped the Japanese advance on Port Moresby.
The Battle of Kokoda consisted of two engagements fought in late July – early August 1942. Forming part of the Kokoda Track campaign of the Second World War, the battle involved military forces from Australia, supported by the United States, fighting against Japanese troops from Major General Tomitaro Horii's South Seas Detachment who had landed around Buna and Gona in Papua mid-July 1942, with the intent of capturing Port Moresby to the south via the overland route.
The Battle of Buna–Gona was part of the New Guinea campaign in the Pacific Theatre during World War II. It followed the conclusion of the Kokoda Track campaign and lasted from 16 November 1942 until 22 January 1943. The battle was conducted by Australian and United States forces against the Japanese beachheads at Buna, Sanananda and Gona.
The First Battle of Eora Creek – Templeton's Crossing was fought from 31 August 1942 to 5 September 1942. Forming part of the Kokoda Track campaign of the Second World War, the battle involved military forces from Australia, supported by the United States, fighting against Japanese troops from Major General Tomitaro Horii's South Seas Detachment who had landed in Papua in mid-1942, with the intent of capturing Port Moresby. The battle was one of three defensive actions fought by the Australians along the Kokoda Track. The fighting resulted in the delay of the Japanese advance south, which allowed the Australians to withdraw to Efogi. Eora Creek village and Templeton's Crossing was subsequently the site of a battle in late October 1942 as the Australian forces pursued the Japanese forces retiring back toward the north coast of Papua.
The Second Battle of Eora Creek – Templeton's Crossing was fought from 11 to 28 October 1942. Forming part of the Kokoda Track campaign of the Second World War, the battle involved military forces from Australia, supported by the United States, fighting against Japanese troops from Major General Tomitaro Horii's South Seas Detachment who had landed in Papua in mid-1942, with the intent of capturing Port Moresby.
