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 41st Infantry Division was an infantry division of the United States Army National Guard composed primarily of units from the Pacific Northwest. The division saw active service in World War I and World War II, receiving the nickname “Jungleers” during the latter.
Operation Chronicle was the Allied invasion of Woodlark and Kiriwina Islands, in the South West Pacific, during World War II. The operation was a subordinate action that formed part of the wider Operation Cartwheel, the advance towards Rabaul. An early planning name for this operation was Operation Coronet. Preliminary actions commenced on 23–24 June 1943 when small reconnaissance parties were landed on both islands. The main operation was executed without opposition on 30 June 1943. Around 16,800 personnel took part, divided into two forces. The United States Army provided the majority of ground troops, which were supported by a United States Marine Corps defense battalion as well as U.S. and Australian aircraft and naval vessels.
The Battle of Vella Lavella was fought from 15 August – 6 October 1943 between the Empire of Japan and the Allied forces from New Zealand and the United States at the end of the New Georgia campaign. Vella Lavella, an island located in the Solomon Islands, had been occupied by Japanese forces early during the war in the Pacific. Following the Battle of Munda Point, the Allies recaptured the island in late 1943, following a decision to bypass a large concentration of Japanese troops on the island of Kolombangara.
The Battle of Arawe was fought between Allied and Japanese forces during the New Britain campaign of World War II. The battle formed part of the Allied Operation Cartwheel and had the objective of serving as a diversion before a larger landing at Cape Gloucester in late December 1943. The Japanese military was expecting an Allied offensive in western New Britain and was reinforcing the region at the time of the Allied landing in the Arawe area on 15 December 1943. The Allies secured Arawe after about a month of intermittent fighting with the outnumbered Japanese force.
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 Battle of the Koromokina Lagoon was fought between the United States Marine Corps and Imperial Japanese Army forces on Bougainville Island. It took place on 7–8 November 1943 during the Bougainville campaign of the Pacific War.
The 162nd Infantry Regiment is a regiment of the Oregon Army National Guard with headquarters in Springfield, Oregon. In January 2006 as part of the Army's transformation towards a modular force, the 1st Battalion, 162nd Infantry Regiment was inactivated. Many members continued to serve with the 2nd Battalion and other units within the 41st Infantry Brigade Combat Team.
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 Battle of Porton Plantation took place near the village of Soraken on Bougainville Island, in the Solomon Islands archipelago during World War II. Involving forces from Australia, New Zealand and Japan, the battle was part of the wider Bougainville campaign, which had begun in late 1943 and lasted until the end of the war in August 1945. The battle formed part of Australian efforts to liberate the northern part of Bougainville.
The Landing at Scarlet Beach took place in New Guinea during the Huon Peninsula campaign of the Second World War, involving forces from Australia, the United States and Japan. Allied forces landed at Scarlet Beach, north of Siki Cove and south of the Song River, to the east of Katika and about 10 kilometres (6.2 mi) north of Finschhafen. The capture of Finschhafen allowed the construction of air base and naval facilities to assist Allied air and naval forces to conduct operations against Japanese bases in New Guinea and New Britain.
The Battle of Finschhafen was part of the Huon Peninsula campaign in New Guinea during World War II and was fought between Australian and Japanese forces. The fighting took place between 22 September and 24 October 1943 following the landing at Scarlet Beach, which was followed by a two-pronged advance on Finschhafen as the Australian 20th Infantry Brigade advanced on the town from the north, while the 22nd Infantry Battalion drove from the south, having advanced from the landing beaches east of Lae. After the capture of Finschhafen, the Japanese forces in the area withdrew towards Sattelberg where they sought to hold the Australians before launching a counteroffensive, which subsequently threatened the landing beach. This attack was repelled by Australian and American forces, with heavy casualties being inflicted on the Japanese. In the aftermath, the Australians went on the offensive, capturing Sattelberg, and then advancing towards the Wareo plateau.
The Battle of the Pimple was part of the Markham and Ramu Valley – Finisterre Range campaign, which consisted of a number of battles fought by Australian and Japanese troops in Papua New Guinea in World War II. Fought on 27 and 28 December 1943, the battle took place as the Australians advanced towards the Japanese strong hold around Shaggy Ridge, and was a preliminary phase in their eventual capture of that position in January 1944. Supported by artillery, mortars, machine guns and fighter-bomber aircraft, the assault was made across a narrow frontage, which was usually not much wider than a single section. Two companies of Australian infantry were committed to the attack, with one securing the initial crest, while the other exploited the position and secured several other smaller features throughout the two days of fighting. In the aftermath, Japanese artillery harassed the Australians holding the position, and subjected them to several counter-attacks, which were eventually defeated.
The Battle of Lababia Ridge was fought from 20–23 June 1943 in the Territory of New Guinea during World War II. Part of the Salamaua–Lae campaign, the battle involved Australian and Japanese troops who clashed on the ridge, which was about 20 kilometres (12 mi) south of Salamaua, near Mubo, over the course of several days. The battle was fought in conjunction with several other actions in the region as the Allies attempted to draw Japanese attention away from Lae, where they launched seaborne landings in mid-September 1943, in conjunction with airborne landings around Nadzab. The fighting around Lababia Ridge took place at the same time as the Battle of Mubo, after two battalions of Japanese infantry launched a counter-attack on a depleted Australian company. The Australians, supported by Royal Australian Air Force fighter-bombers, managed to hold off the initial Japanese attacks before being reinforced by another depleted company. Fighting continued over the course of three days before the Japanese withdrew.
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.
The Battle of Bobdubi was a series of actions fought in the Salamaua area of the Territory of New Guinea between Australian and Japanese forces which took place from 22 April to 19 August 1943, during World War II. Part of the Allied advance on Salamaua, the battle was fought in conjunction with several other actions in the region as the Allies attempted to draw Japanese attention away from Lae, where they launched seaborne landings in mid-September 1943 in conjunction with airborne landings around Nadzab. The initial phase of the fighting around Bobdubi was characterised mainly by small unit harassment and reconnaissance operations, while the second phase saw the capture of a number of Japanese defensive positions in locations dubbed "Old Vickers", "Timbered Knoll", and the "Coconuts".
The Battle of Roosevelt Ridge was fought between 21 July and 14 August 1943 between US and Japanese forces in the Salamaua area of the Territory of New Guinea during World War II. The battle was fought in conjunction with several other actions of the Salamaua–Lae campaign. Throughout the first half of 1943, Australian forces had clashed with the Japanese around Wau and then Mubo as they had pushed the Japanese back towards Salamaua. As the campaign had developed, the Japanese had brought in reinforcements from elsewhere in New Guinea, effectively reducing their garrison, particularly around Lae. Following fighting on Lababia Ridge, the Australians had begun securing positions around Bobdubi, with a view to extending towards Mount Tambu.
The Battle of Mount Tambu was a series of actions fought in the Salamaua area of the Territory of New Guinea between Allied and Japanese forces, which took place between 16 July and 18 August 1943, during World War II. The battle formed part of the wider Salamaua–Lae campaign and was fought in the final stages of the campaign, which had seen a combined Australian and US force advance from Wau towards Salamaua following the repulse of the Japanese attack on Wau in late January and early February 1943. After several frontal assaults on the position by Australian and US infantrymen were rebuffed by determined Japanese defenders, an indirect approach was sought and flanking moves were undertaken to cut off the Japanese supply route along the Komiatum Track. This succeeded in eventually forcing the Japanese off the position as they withdrew to avoid encirclement.
The Battle of Talasea was fought in the Pacific theater of World War II between Japanese and Allied forces. Dubbed "Operation Appease" by the Allies, the battle was part of the wider Operations Dexterity and Cartwheel, and took place on the island of New Britain, Territory of New Guinea, in March 1944 as primarily US forces, with limited Australian support, carried out an amphibious landing to capture the Talasea area of the Willaumez Peninsula, as part of follow-up operations as the Japanese began withdrawing east towards Rabaul following heavy fighting around Cape Gloucester earlier in the year. The assault force consisted of a regimental combat team formed around the 5th Marines, which landed on the western coast of the Willaumez Peninsula, on the western side of a narrow isthmus near the Volupai Plantation. Following the initial landing, the Marines advanced east towards the emergency landing strip at Talasea on the opposite coast. Their advance south was stymied by a small group of Japanese defenders who prevented the US troops from advancing quickly enough to cut off the withdrawal of the Japanese force falling back from Cape Gloucester.
