Operation Cartwheel (1943–1944) was a major military operation for the Allies in the Pacific theatre of World War II. Cartwheel was an operation aimed at neutralising the major Japanese base at Rabaul. The operation was directed by the Supreme Allied Commander in the South West Pacific Area (SWPA), General Douglas MacArthur, whose forces had advanced along the northeast coast of New Guinea and occupied nearby islands. Allied forces from the South Pacific Area, under Admiral William Halsey, advanced through the Solomon Islands toward Bougainville. The Allied forces involved were from Australia, the Netherlands, New Zealand, the US and various Pacific Islands.
The Allies of World War II conducted an air attack upon a cruiser force at the major Japanese base of Rabaul in November 1943. In response to the Allied invasion of Bougainville, the Japanese had brought a strong cruiser force down from Truk, their major naval base in the Caroline Islands about 800 miles north of Rabaul, to Rabaul in preparation for a night engagement against the Allied supply and support shipping. Allied carrier- and land-based planes attacked the Japanese ships, airfields, and port facilities on the island of New Britain to protect the Allied amphibious invasion of Bougainville. As a result of the Rabaul raids, the Japanese naval forces could no longer threaten the landings. The success of the raid began to change the strongly held belief that carrier-based air forces could not challenge land-based air forces.
The Battle of Cape St. George was a naval battle of the Pacific campaign of World War II fought on 25 November 1943, between Cape St. George, New Ireland, and Buka Island. It was the last engagement of surface ships in the Solomon Islands campaign. During the engagement, a force of five US Navy destroyers led by Captain Arleigh Burke intercepted a similar sized Japanese force that was withdrawing from Buka towards Rabaul, having landed reinforcements on the island. In the ensuing fight, three Japanese destroyers were sunk and one was damaged, with no losses amongst the US forces.
The Battle of Rabaul, also known by the Japanese as Operation R, an instigating action of the New Guinea campaign, was fought on the island of New Britain in the Australian Territory of New Guinea, from 23 January into February 1942. It was a strategically significant defeat of Allied forces by Japan in the Pacific campaign of World War II, with the Japanese invasion force quickly overwhelming the small Australian garrison, the majority of which was either killed or captured. Hostilities on the neighbouring island of New Ireland are usually considered to be part of the same battle. Rabaul was significant because of its proximity to the Japanese territory of the Caroline Islands, site of a major Imperial Japanese Navy base on Truk.
The New Georgia campaign was a series of land and naval battles of the Pacific Theater of World War II between Allied forces and the Empire of Japan. It was part of Operation Cartwheel, the Allied strategy in the South Pacific to isolate the Japanese base around Rabaul. The campaign took place in the New Georgia Islands in the central Solomon Islands and followed the Allied capture of the Russell Islands. The main fighting took place on New Georgia itself, although significant actions also took place around the island chain throughout the campaign.
The Bougainville campaign was a series of land and naval battles of the Pacific campaign of World War II between Allied forces and the Empire of Japan, named after the island of Bougainville. It was part of Operation Cartwheel, the Allied grand strategy in the South Pacific.
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 Solomon Islands campaign was a major campaign of the Pacific War of World War II. The campaign began with Japanese landings and capture of several areas in the British Solomon Islands and Bougainville, in the Territory of New Guinea, during the first six months of 1942. The Japanese occupied these locations and began the construction of several naval and air bases with the goals of protecting the flank of the Japanese offensive in New Guinea, establishing a security barrier for the major Japanese base at Rabaul on New Britain, and providing bases for interdicting supply lines between the Allied powers of the United States and Australia and New Zealand.
The New Britain campaign was a World War II campaign fought between Allied and Imperial Japanese forces. The campaign was initiated by the Allies in late 1943 as part of a major offensive which aimed to neutralise the important Japanese base at Rabaul, the capital of New Britain, and was conducted in two phases between December 1943 and the end of the war in August 1945.
The Battle of the Treasury Islands was a Second World War battle that took place between 27 October and 12 November 1943 on the Treasury Islands group, part of the Solomon Islands. The battle formed part of the wider Pacific War and involved New Zealand and US forces fighting against Japanese troops. The majority of the ground forces were provided by the New Zealand 3rd Division.
The Battle of the Green Islands or Operation Squarepeg was fought from 15 to 20 February 1944, between Imperial Japan and Allied forces from the New Zealand 3rd Division and the United States. Undertaken after landings to secure lodgments on New Britain and Bougainville, the main focus of the operation was the capture of Nissan Island, which was secured by New Zealand forces after only a short ground campaign. At only very limited cost in terms of casualties, the Allied operation resulted in the capture of several small atolls in the island chain, which were subsequently used to support air and naval operations focused on reducing the main Japanese base on Rabaul.
The invasion of Tulagi, on 3–4 May 1942, was part of Operation Mo, the Empire of Japan's strategy in the South Pacific and South West Pacific Area in 1942. The plan called for Imperial Japanese Navy troops to capture Tulagi and nearby islands in the British Solomon Islands Protectorate. The occupation of Tulagi by the Japanese was intended to cover the flank of and provide reconnaissance support for Japanese forces that were advancing on Port Moresby in New Guinea, provide greater defensive depth for the major Japanese base at Rabaul, and serve as a base for Japanese forces to threaten and interdict the supply and communication routes between the United States and Australia and New Zealand.
The Landings at Cape Torokina, also known as Operation Cherryblossom, took place at the beginning of the Bougainville campaign in World War II. The amphibious landings were carried out by elements of the United States Marine Corps in November 1943 on Bougainville Island in the South Pacific, as part of Allied efforts to advance towards the main Japanese base around Rabaul under Operation Cartwheel. Coming in the wake of Allied successes at Guadalcanal and in the central Solomons, the landings were intended to secure a beachhead with the purpose of establishing several bases from which to project air and naval power closer towards Rabaul, in an effort to neutralize the large Japanese force that had been established there.
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.
The Battle of Munda Point was a battle from 22 July – 5 August 1943 between primarily United States Army and Imperial Japanese Army forces during the New Georgia campaign in the Solomon Islands in the Pacific War. The battle took place following a landing by U.S. troops on the western coast of New Georgia from Rendova Island, as part of an effort to capture the Japanese airfield that had been constructed at Munda Point. This advance had become bogged down, and while the Allies brought forward reinforcements and supplies, the Japanese had launched a counterattack on 17–18 July. This effort was ultimately unsuccessful, and afterwards U.S. forces launched a corps-level assault to reinvigorate their effort to capture the airfield. Against this drive, Japanese defenders from three infantry regiments offered stubborn resistance but were ultimately forced to withdraw, allowing U.S. forces to capture the airfield on 5 August. The airfield later played an important role in supporting the Allied campaign on Bougainville in late 1943.
The invasion of Salamaua–Lae, called Operation SR by the Japanese, was an operation by Imperial Japanese forces to occupy the Salamaua–Lae area in the Territory of New Guinea during the Pacific campaign of World War II. The Japanese invaded and occupied the location in order to construct an airfield and establish a base to cover and support the advance of Japanese forces into the eastern New Guinea and Coral Sea areas. As the Japanese arrived, the tiny Australian garrison in the region retreated and did not oppose the invasion.
The Battle of Ratsua occurred during the Second World War and involved Australian and Japanese forces. Part of the wider Bougainville Campaign of the Pacific theatre, the battle took place in the northern sector of Bougainville between June and August 1945. The main forces that took part in the fighting were the Australian 23rd Brigade and the Japanese 87th Naval Garrison Force.
Operation I-Go was an aerial counter-offensive launched by Imperial Japanese forces against Allied forces during the Solomon Islands and New Guinea Campaigns in the Pacific Theater of World War II. Taking place from 1–16 April 1943, during the operation, Japanese aircraft – primarily from Imperial Japanese Navy units under the command of Admirals Isoroku Yamamoto and Jinichi Kusaka – attacked Allied ships, aircraft, and land installations in the southeast Solomon Islands and New Guinea. The goal of the operation was to halt the Allied offensives in New Guinea and the Solomons and to give Japan time to prepare a new set of defenses in response to recent defeats to the Allies in the Battle of Guadalcanal and in New Guinea at Buna–Gona, Wau, and the Bismarck Sea.
Rabaul is a town in eastern New Britain, Papua New Guinea. Japanese forces landed on Rabaul on 23 January 1942, capturing it by February 1942. The former Australian territory was transformed into a major Japanese naval and air installation. The Japanese heavily relied on it, using it as a launching point for Japanese reinforcements to New Guinea and Guadalcanal. Throughout the Solomon Islands campaign, neutralizing Rabaul became the primary objective of the Allied effort in the Solomons.
The Japanese occupation of the Solomon Islands was the period in the history of the Solomon Islands between 1942 and 1945 when Imperial Japanese forces occupied Solomon Islands during World War II.
