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.
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 2/6th Battalion was an infantry battalion of the Australian Army that served during the Second World War. Raised in October 1939 as part of the all-volunteer Second Australian Imperial Force, the battalion formed part of the 6th Division and was among the first troops raised by Australia during the war. Departing Australia in early 1940, the 2/6th were deployed to the Middle East where in January 1941, it took part in the first action of the war by Australian ground forces, the Battle of Bardia, which was followed by further actions around Tobruk. Later, the 2/6th were dispatched to take part in the Battle of Greece, although they were evacuated after only a short involvement in the campaign. Some members of the battalion subsequently fought on Crete with a composite 17th Brigade battalion, and the battalion had to be re-formed in Palestine before being sent to Syria in 1941–42, where they formed part of the Allied occupation force that was established there in the aftermath of the Syria–Lebanon campaign.
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 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.
I Corps was an Australian Army corps, one of three that were raised by the Army during World War II. It was the main Australian operational corps for much of the war. Various Australian and other Allied divisions came under its control at different times. In 1940–1942, the corps was based in the Mediterranean and Middle Eastern theatres, and controlled forces in action against the Germans, Italians and later the Vichy French in North Africa, Greece and Syria–Lebanon.
The Battle of Wau, 29 January – 4 February 1943, was a battle in the New Guinea campaign of World War II. Forces of the Empire of Japan sailed from Rabaul and crossed the Solomon Sea and, despite Allied air attacks, successfully reached Lae, where they disembarked. Japanese troops then advanced overland on Wau, an Australian base that potentially threatened the Japanese positions at Salamaua and Lae. A race developed between the Japanese moving overland, hampered by the terrain, and the Australians, moving by air, hampered by the weather. By the time the Japanese reached the Wau area after a trek over the mountains, the Australian defenders had been greatly reinforced by air. In the battle that followed, despite achieving tactical surprise by approaching from an unexpected direction, the Japanese attackers were unable to capture Wau.
The Salamaua–Lae campaign was a series of actions in the New Guinea campaign of World War II. Australian and United States forces sought to capture two major Japanese bases, one in the town of Lae, and another one at Salamaua. The campaign to take the Salamaua and Lae area began after the successful defence of Wau in late January, which was followed up by an Australian advance towards Mubo as the Japanese troops that had attacked Wau withdrew to positions around Mubo. A series of actions followed over the course of several months as the Australian 3rd Division advanced north-east towards Salamaua. After an amphibious landing at Nassau Bay, the Australians were reinforced by a US regimental combat team, which subsequently advanced north up the coast.
The New Guinea Volunteer Rifles (NGVR) was an infantry battalion of the Australian Army. It was initially raised as a unit of the Militia from white Australian and European expatriates in New Guinea upon the outbreak of the Second World War in 1939, before being activated for full-time service following the Japanese landings in early 1942. NGVR personnel then helped rescue survivors of Lark Force from Rabaul in February and March 1942. Between March and May, the NGVR monitored the Japanese bases which had been established in the Huon Gulf region, being the only Allied force in the area until the arrival of Kanga Force at Wau in May. The battalion subsequently established observation posts overlooking the main approaches and reported on Japanese movements.
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 Papuan Infantry Battalion (PIB) was a unit of the Australian Army raised in the Territory of Papua for service during the Second World War. Formed in early 1940 in Port Moresby to help defend the territory in the event of a Japanese invasion, its soldiers were primarily Papuan natives led by Australian officers and non-commissioned officers. Following the outbreak of the Pacific War, the PIB served in many of the Allied campaigns in New Guinea; however, due to the nature of its role its sub-units mainly operated separately, attached to larger Australian and US Army units and formations. Slow in forming, the first members of the PIB were not officially posted in until March 1941. By 1942 it consisted of only three companies, all of which were under-strength and poorly equipped. It was subsequently employed on scouting, reconnaissance and surveillance patrols against the Japanese, where the natural bushcraft of its native soldiers could be used to their advantage. The PIB was sent forward in June 1942 to patrol the northern coast of Papua and was dispersed over a wide area. These small parties were the first to make contact with the Imperial Japanese forces upon their landing in Papua, before participating in the Kokoda Track campaign. As part of Maroubra Force, the PIB fought alongside the Australian 39th Battalion at Kokoda, Deniki, and Isurava as the Japanese forced them back along the Kokoda track, but was withdrawn before the campaign finally turned in favour of the Australians.
The Landing at Lae was an amphibious landing to the east of Lae and then the subsequent advance on the town during the Salamaua–Lae campaign of World War II. Part of Operation Postern, which was undertaken to capture the Japanese base at Lae, the landing was undertaken between 4 and 6 September 1943 by Australian troops from the 9th Division, supported by US naval forces from the VII Amphibious Force. The first major amphibious operation undertaken by the Australian Army since the failed Gallipoli Campaign, the Australians invested a significant amount of effort into planning the operation.
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 11th Division was an Australian Army unit formed during World War II by the renaming of Milne Force in December 1942. Predominately a Militia formation, the division's main role during the war was as a base command headquarters, although elements saw action in New Guinea against Japanese forces during the Finisterre Range campaign and in New Britain. It was disbanded in July 1946.
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 2/1st Field Regiment was an Australian Army artillery regiment raised as part of the all volunteer Second Australian Imperial Force during World War II. Formed in October 1939, the regiment was assigned to the 6th Division. Shortly after it was raised, the regiment was deployed to the Middle East, where it was briefly re-roled as an anti-aircraft regiment before returning to the field artillery role. In 1941, the regiment served in North Africa and in Greece, before being withdrawn back to Australia in early 1942, following Japan's entry into the war. In late 1942, and early 1943, the regiment took part in the defence of Port Moresby during the fighting along the Kokoda Track, before taking part in the Battle of Buna–Gona and the defence of Wau, remaining in New Guinea on garrison duties until August 1943. Withdrawn to Australia, a long period of training followed before the regiment took part in its final campaign of the war Aitape–Wewak campaign in 1945.
The 1st Mountain Battery was an Australian Army artillery battery formed in July 1942, that served during the Second World War, seeing action against the Japanese during the Battle of Buna–Gona and the Salamaua–Lae campaign in 1942–43. The unit was added to the 1st Parachute Battalion in August 1944 providing an organic indirect fire support, equipped with Short 25-pounder guns, but did not see further action in this role. The battery was disbanded in 1946.
The Battle of Mubo was a series of actions in the Mubo area of the Territory of New Guinea between Australian and Japanese forces which took place between 22 April and 14 July 1943, during World War II. The battle formed part of the wider Salamaua–Lae campaign, and was fought in the early stages of the campaign. The battle followed the successful defence of the airfield around Wau by the Australians in late January 1943, after the Japanese had attempted to infiltrate the Australian positions with two infantry battalions.
