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 in the first action in the Bougainville campaign of World War II. It 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.
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.
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 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 Raid on Choiseul was a small unit engagement that occurred from 28 October to 3 November 1943, during the Solomon Islands campaign of the Pacific War. The raid was launched to divert the Japanese from the Allied landings at Cape Torokina on Bougainville Island.
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 Piva Forks, also known as the Battle of Numa–Numa Trail, was an engagement that took place during the Bougainville campaign in World War II. Occurring between 18 and 25 November 1943 on Bougainville Island in the South Pacific, the battle involved troops from the United States Marine Corps and the United States Army fighting against Imperial Japanese Army forces and took place amidst the context of the expansion of a beachhead that US forces had established around Torokina on the western side of the island.
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 Battle of Viru Harbor was a battle of the Pacific campaign of World War II that took place on New Georgia island during the New Georgia campaign from 28 June – 1 July 1943. It was one of the first actions of the campaign and involved an overland advance by elements of a Marine Raider battalion, supported by a United States Army infantry company. Supported by airstrikes, the Marines carried out an enveloping attack on the Japanese defenders around the harbor and forced them to withdraw. The harbor was subsequently used by US forces to support further operations, although plans to build a PT boat base in the area were later canceled when the harbor was found to be unsuitable.
The Landings on Rendova were amphibious military assaults by United States Army, Marine Corps and Navy forces on Rendova Island in the Solomon Islands on 30 June 1943. The small Japanese garrison was quickly overwhelmed by US troops, but the island was subjected to heavy attack by Japanese aircraft over several days. The landings were some of the first Allied landings during the New Georgia campaign of the Pacific War and were successful in securing the island and providing a base from which the Allies could support the subsequent invasion of New Georgia island and the eventual capture of Munda airfield in early August 1943.
The Battle of Wickham Anchorage took place during the New Georgia campaign in the Solomon Islands during the Pacific War from 30 June – 3 July 1943. During the operation US Marines and US Army troops landed by ship around Oleana Bay on Vangunu Island and advanced overland towards the anchorage where they attacked a garrison of Imperial Japanese Navy and Army troops. The purpose of the attack by the US was to secure the lines of communication and supply between Allied forces involved in the New Georgia campaign and Allied bases in the southern Solomons. The US forces were successful in driving the Japanese garrison from the area and securing the anchorage, which would later be used to stage landing craft for subsequent operations.
The New Georgia counterattack was a counterattack on 17–18 July 1943 by mainly Imperial Japanese Army troops against United States Army forces during the New Georgia campaign in the Solomon Islands. The U.S. and its allies were attempting to capture an airfield constructed by the Japanese at Munda Point on New Georgia with which to support further advances towards the main Japanese base around Rabaul as part of Operation Cartwheel.
The Battle of Munda Point was a battle in World War II between American and Japanese forces from 2 July to 5 August 1943 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 Battle of the Coconut Grove was a battle between United States Marine Corps and Imperial Japanese Army forces on Bougainville Island during the Pacific War. The battle took place on 13–14 November 1943 during the Bougainville campaign, coming in the wake of a successful landing around Cape Torokina at the start of November, as part of the advance towards Rabaul as part of Operation Cartwheel.
The Raid onKoiari was a battle that occurred between 28 and 29 November 1943 in the Pacific theater of World War II between American and Japanese forces. Part of the Bougainville campaign, the raid involved a landing by a battalion-sized force of United States Marines to harass Imperial Japanese Army troops on Bougainville Island. The raid was a failure for the Americans as they were attacked by a larger-than-expected Japanese force and as a result the Marines were withdrawn from the beachhead without having achieved any of their objectives.
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.
The Bougainville counterattack, also known as the Second Battle of Torokina, was an unsuccessful Japanese offensive against the Allied base at Cape Torokina on Bougainville Island during the Pacific Theater of World War II. The Japanese attack began on 8 March 1944 after months of preparation and was repulsed by United States Army forces in fighting which lasted until 25 March. The attack was hampered by inaccurate intelligence and poor planning and was pushed back by the well-prepared Allied defenders, who greatly outnumbered the Japanese force. The Japanese suffered severe casualties, while Allied losses were light.
The Battle for Piva Trail was a battle between United States Marine Corps and Imperial Japanese Army forces on Bougainville Island. The battle took place on 8–9 November 1943 during the Bougainville campaign of the Pacific War in the days following the US landings at Cape Torokina earlier in the month.
The Battle of Arundel Island was fought from 27 August – 21 September 1943, primarily between United States Army and Imperial Japanese Army forces on Arundel Island during the New Georgia campaign in the Pacific War. The battle took place towards the end of the campaign after the capture of Munda airfield and mopping up operations in western New Georgia had resulted in the Japanese evacuation of mainland New Georgia. The US high command decided to occupy the island so that it could be used as a base for artillery to fire on the main Japanese troop concentration on Kolombangara.
