The 6th Division was an infantry division of the Australian Army. It was raised briefly in 1917 during World War I, but was broken up to provide reinforcements before seeing action. It was not re-raised until the outbreak of World War II, when it was formed as a unit of the Second Australian Imperial Force. Throughout 1940–41 it served in the North African Campaign, the Greek campaign, on Crete and in Syria, fighting against the Germans, Italians and Vichy French. In 1942, the division left the Middle East and returned to Australia to meet the threat of Japan's entry into the war. Part of the division garrisoned Ceylon for a short period of time, before the division was committed to the New Guinea campaign. In New Guinea, its component brigades had a major role in the successful counter-offensive along the Kokoda Track, at Buna–Gona and around Salamaua–Lae in 1942–43. Throughout late 1943–44, the division was re-organised in Australia before being committed as a complete formation to one of the last Australian operations of the war around Aitape–Wewak in 1944–45.
The United States 32nd Infantry Division was formed from Army National Guard units from Wisconsin and Michigan and fought primarily during World War I and World War II. With roots as the Iron Brigade in the American Civil War, the division's ancestral units came to be referred to as the Iron Jaw Division. During tough combat in France in World War I, it soon acquired from the French the nickname Les Terribles, referring to its fortitude in advancing over terrain others could not. It was the first allied division to pierce the German Hindenburg Line of defense, and the 32nd then adopted its shoulder patch; a line shot through with a red arrow, to signify its tenacity in piercing the enemy line. It then became known as the Red Arrow Division.
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 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.
Tomitarō Horii was a lieutenant general in the Imperial Japanese Army during World War II. After graduating from the Imperial Japanese Army Academy in 1911, Horii served in China before undertaking a variety of regimental appointments. Following Japan's entry into World War II, he commanded a division during the capture of Guam before commanding the Japanese force that had been given the task of capturing Port Moresby. In November 1942, in the retreat from Oivi–Gorari, Horii drowned while attempting to canoe down the Kumusi River to reach Japanese forces defending Buna–Gona. His canoe was swept out to sea and capsized.
The '5th Division' was an infantry division of the Imperial Japanese Army. Its call sign was the Koi (Carp) Division. The 5th Division was formed in Hiroshima in January 1871 as the Hiroshima Garrison, one of six regional commands created in the fledgling Imperial Japanese Army. Its personnel were drafted from Hiroshima, Yamaguchi and Shimane.
New Guinea Force was a military command unit for Australian, United States and native troops from the Territories of Papua and New Guinea serving in the New Guinea campaign during World War II. Formed in April 1942, when the Australian First Army was formed from the Australian I Corps after it returned from the Middle East, it was responsible for planning and directing all operations within the territory up until October 1944. General Headquarters Southwest Pacific Area Operational Instruction No.7 of 25 May 1942, issued by Commander-Allied-Forces, General Douglas MacArthur, placed all Australian and US Army, Air Force and Navy Forces in the Port Moresby Area under the control of New Guinea Force. Over the course of its existence, New Guinea Force was commanded by some of the Australian Army's most notable commanders, including Sydney Rowell, Sir Edmund Herring and Sir Leslie Morshead.
The 2/16th Battalion was an infantry battalion of the Australian Army, serving during World War II. Attached to the 21st Brigade that was assigned to the 7th Division, the 2/16th was raised in 1940 as part of the Second Australian Imperial Force from volunteers drawn mainly from the state of Western Australia. After training in Australia, the battalion was deployed to the Middle East where it undertook defensive duties along the Egyptian–Libyan border in early 1941 before taking part in the Syria–Lebanon campaign, fighting against Vichy French forces in June and July. At the conclusion of the campaign, the 2/16th remained in Lebanon, contributing to the Allied occupation force there, before returning to Australia in early 1942 following Japan's entry into the war. In August 1942, they were committed to the fighting along the Kokoda Track and then later fought around Buna and Gona. After a period of rest and reorganisation in Australia, the battalion fought around Lae and then took part in the Finisterre Range campaign in 1943–44. Its final campaign of the war came in Borneo in July 1945. At the end of the war, the 2/16th were disbanded in January 1946.
The 38th Division was an infantry division of the Imperial Japanese Army, activated 30 June 1939 in Nagoya, simultaneously with the 39th, 40th and 41st Divisions. Its call sign was the Swamp Division.
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 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 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 Ioribaiwa took place between 14 and 16 September 1942, during the Kokoda Track campaign in Papua during the Second World War. Involving forces from Australia, the United States, and Japan, the fighting centred on a high feature known as Ioribaiwa Ridge, south of Ofi Creek on the Kokoda Track, in the Territory of Papua. It was the last of three defensive battles fought by the Australians along the Kokoda Track to halt the Japanese advance from the north coast of Papua towards Port Moresby.
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 Allied advance on the Japanese positions at Buna–Gona was made by the 16th and 25th Brigades of the Australian 7th Division and the 126th and 128th Infantry Regiments of the US 32nd Infantry Division. During the course of the battle, a further four infantry brigades, two infantry regiments and an armoured squadron of 19 M3 Stuart tanks were deployed.
