The Guadalcanal campaign, also known as the Battle of Guadalcanal and codenamed Operation Watchtower by American forces, was a military campaign fought between 7 August 1942 and 9 February 1943 on and around the island of Guadalcanal in the Pacific theater of World War II. It was the first major land offensive by Allied forces against the Empire of Japan.
The Battle of Empress Augusta Bay, on 1–2 November 1943 – also known as the Battle of Gazelle Bay, Operation Cherry Blossom, and in Japanese sources as the Sea Battle off Bougainville Island (ブーゲンビル島沖海戦) – was a naval battle fought at night in Empress Augusta Bay near Bougainville Island. The naval battle was a result of Allied landings at Cape Torokina with the bay in the first action in the Bougainville campaign of World War II and may also be considered as part of the Solomons and New Guinea campaigns. The battle was significant as part of a broader Allied strategy—known as Operation Cartwheel—aimed at isolating and surrounding the major Japanese base at Rabaul. The intention was to establish a beachhead on Bougainville, within which an airfield would be built.
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 bombing of Rabaul in November 1943 was an air attack conducted by the Allies of World War II upon a cruiser force at the major Japanese base of Rabaul. In response to the Allied invasion of Bougainville, the Japanese had brought a strong cruiser force down to Rabaul from Truk, their major naval base in the Caroline Islands about 800 miles north of 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 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.
Cactus Air Force refers to the ensemble of Allied air power assigned to the island of Guadalcanal from August 1942 until December 1942 during the most heavily contested phases of the Guadalcanal Campaign, particularly those operating from Henderson Field. The term "Cactus" comes from the Allied code name for the island. In 1943, the Cactus Air Force was absorbed into AirSols, a joint command of Allied air units in the Solomon Islands.
The South Pacific Area (SOPAC) was a multinational U.S.-led military command active during World War II. It was a part of the U.S. Pacific Ocean Areas under Admiral Chester Nimitz.
No. 25 Squadron of the Royal New Zealand Air Force was formed at Seagrove, Auckland in July 1943 with Douglas SBD Dauntless dive bombers and served in the Southern Pacific based at the Piva Airstrip on Bougainville, flying missions against Japanese forces on Bougainville and at Rabaul. It was disbanded in May 1944 and reformed as a fighter/ground attack squadron flying F4U Corsairs. It served in Santo, Guadalcanal, Los Negros and Emirau, before returning to New Zealand and being disbanded in September 1945. A SBD-4 Dauntless operated by 25 Squadron was for a time preserved in the Royal New Zealand Air Force Museum at Wigram, displayed in the condition which it was recovered after being lost with its crew while on a training mission at Espiritu Santo. One of the SBD-5 aircraft operated by 25 Squadron has been restored to flying condition in America for the "Planes of Fame" museum, in the colour scheme of an American aircraft.
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.
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 Cape Gloucester was fought in the Pacific theater of World War II between Japanese and Allied forces on the island of New Britain, Territory of New Guinea, between 26 December 1943 and 16 January 1944. Codenamed Operation Backhander, the US landing formed part of the wider Operation Cartwheel, the main Allied strategy in the South West Pacific Area and Pacific Ocean Areas during 1943–1944. It was the second landing the US 1st Marine Division had conducted during the war thus far, after Guadalcanal. The objective of the operation was to capture the two Japanese airfields near Cape Gloucester that were defended by elements of the Japanese 17th Division.
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 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 of the Pacific War.
Francis Patrick Mulcahy CBE was a general and commander in the United States Marine Corps during World War II. Mulcahy commanded the 2nd Marine Aircraft Wing, the Cactus Air Force, and the Tactical Air Force, Tenth Army.
The Landing on Emirau was the last of the series of operations that made up Operation Cartwheel, General Douglas MacArthur's strategy for the encirclement of the major Japanese base at Rabaul. A force of nearly 4,000 United States Marines landed on the island of Emirau on 20 March 1944. The island was not occupied by the Japanese and there was no fighting. It was developed into an airbase which formed the final link in the chain of bases surrounding Rabaul. The isolation of Rabaul permitted MacArthur to turn his attention westward and commence his drive along the north coast of New Guinea toward the Philippines.
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, 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 to give Japan time to prepare a new set of defenses in response to recent defeats in the Guadalcanal campaign and in New Guinea at Buna–Gona, Wau, and the Bismarck Sea.
The neutralisation of Rabaul was an Allied campaign to render useless the Imperial Japanese base at Rabaul in eastern New Britain, Papua New Guinea. Japanese forces landed on Rabaul on 23 January 1942, capturing it by February 1942, after which the harbor and town were 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.
Ralph Johnson Mitchell was a decorated aviation officer of the United States. He is most noted for his service as Director of Aviation during the years 1939–1943 and commanding officer of the 1st Marine Aircraft Wing during World War II.
