Guadalcanal
Guadalcanal (; indigenous name: ''Isatabu'') is the principal island in Guadalcanal Province of Solomon Islands, located in the south-western Pacific, northeast of Australia. It is the largest island in the Solomon Islands by area, and the second by population (after Malaita). The island is mainly covered in dense tropical rainforest and has a mountainous hinterland. Guadalcanal's first charting by westerners was under the Spanish expedition of Álvaro de Mendaña in 1568. The name comes from the village of Guadalcanal, in the province of Seville, in Andalusia, Spain, birthplace of Pedro de Ortega Valencia, a member of Mendaña's expedition. During 1942–43, it was the scene of the Guadalcanal Campaign and saw bitter fighting between Japanese and US troops. The Americans were ultimately victorious. At the end of World War II, Honiara, on the north coast of Guadalcanal, became the new capital of the British Solomon Islands Protectorate. Geography Guadalcanal is the lar ...

It took place from 12–14 September 1942, on Guadalcanal in the Solomon Islands, and was the second of three separate major Japanese ground offensives during the Guadalcanal campaign.

Battle Of Milne Bay
The Battle of Milne Bay (25 August – 7 September 1942), also known as Operation RE or the Battle of Rabi (ラビの戦い) by the Japanese, was a battle of the Pacific campaign of World War II. Japanese marines, known as ''Kaigun Tokubetsu Rikusentai'' (Special Naval Landing Forces), with two small tanks attacked the Allied airfields at Milne Bay that had been established on the eastern tip of New Guinea. Due to poor intelligence work, the Japanese miscalculated the size of the predominantly Australian garrison and, believing that the airfields were defended by only two or three companies, initially landed a force roughly equivalent in size to one battalion on 25 August 1942. The Allies, forewarned by intelligence from Ultra, had heavily reinforced the garrison. Despite suffering a significant setback at the outset, when part of their small invasion force had its landing craft destroyed by Royal Australian Air Force aircraft as they attempted to land on the coast behind t ...

Rabaul
Rabaul () is a township in the East New Britain province of Papua New Guinea, on the island of New Britain. It lies about 600 kilometres to the east of the island of New Guinea. Rabaul was the provincial capital and most important settlement in the province until it was destroyed in 1994 by falling ash from a volcanic eruption in its harbour. During the eruption, ash was sent thousands of metres into the air, and the subsequent rain of ash caused 80% of the buildings in Rabaul to collapse. After the eruption the capital was moved to Kokopo, about away. Rabaul is continually threatened by volcanic activity, because it is on the edge of the Rabaul caldera, a flooded caldera of a large pyroclastic shield. Rabaul was planned and built around the harbour area known as Simpsonhafen (Simpson Harbour) during the German New Guinea administration, which controlled the region between 1884 and formally through 1919. Rabaul was selected as the capital of the German New Guinea administratio ...

Operation Mo
or the Port Moresby Operation was a Japanese plan to take control of the Australian Territory of New Guinea during World War II as well as other locations in the South Pacific. The goal was to isolate Australia and New Zealand from the Allied United States. The plan was developed by the Imperial Japanese Navy and supported by Admiral Isoroku Yamamoto, the commander-in-chief of the Combined Fleet, but the operation was eventually abandoned. Background When the Japanese Navy was planning the New Guinea Campaign (air strikes against Lae and Salamaua, disembarkation in Huon Gulf, New Britain (Rabaul), New Ireland (Kavieng), Finch Harbor (also called Finschhafen), and the capture of Morobe and Buna), strategists envisioned those territories as support points to implement the capture of Port Moresby. The implementation of these operations was assigned to the Japanese Naval task force led by Admiral Chūichi Nagumo, after completing the Java campaign. Another important step was t ...

Tulagi
Tulagi, less commonly known as Tulaghi, is a small island——in Solomon Islands, just off the south coast of Ngella Sule. The town of the same name on the island (pop. 1,750) was the capital of the British Solomon Islands Protectorate from 1896 to 1942 and is today the capital of the Central Province. The capital of what is now the state of Solomon Islands moved to Honiara, Guadalcanal, after World War II. The island was originally chosen by the British as a comparatively isolated and healthier alternative to the disease-ridden larger islands of the Solomon Islands archipelago. In October 2019, the government of Central Province signed a deal to grant the 75-year lease of the entire island of Tulagi to a Chinese company China Sam Enterprise Group. However, this was declared unconstitutional by the Solomon Islands parliament after a week and, consequently, the deal was cancelled.
