Guadalcanal

Guadalcanal is the largest island in the Solomon Islands.

It is located in the southwestern Pacific Ocean, northeast of Australia. The island is the most significant landmass in Guadalcanal Province. While it is the largest by area, it is the second-most populous island in the country. Malaita remains the most populous island in the Solomon Islands. Most of the land is covered by dense tropical rainforest. A mountainous hinterland rises behind the coastal areas.

The geography of the island is defined by high peaks and long rivers. Mount Popomanaseu is the highest point on the island. It is also the highest peak in the entire Solomon Islands, reaching an elevation of 2,335 meters above sea level. The island features many other significant peaks, such as Mount Makarakomburu and Mount Tanareirei. Water flows through various river systems across the terrain. The Mbokokimbo River is the longest river on the island, stretching 140 kilometers. Other notable rivers include the Lungga, Mbalisuna, and Matanikau rivers.

Human history on Guadalcanal stretches back thousands of years. Archaeological evidence from Poha Cave and Vatuluma Posovi shows habitation as early as 4500–2500 BC. Between 1200 and 800 BC, the Austronesian Lapita peoples migrated to the islands. In 1568, the Spanish explorer Álvaro de Mendaña de Neira led the first European expedition to see the island. He named it after the village of Guadalcanal in Andalusia, Spain. This name honored Pedro de Ortega Valencia, a member of the expedition. Over time, European settlers, whalers, and missionaries arrived. In the 1860s, British authorities sent about 60,000 Solomon Islanders to work on plantations in Australia or Fiji. By 1893, the British Solomon Islands Protectorate was proclaimed, which included Guadalcanal.

During World War II, the island became a central site of intense conflict. In May 1942, Japanese forces occupied the island. They began constructing an airfield at Lunga Point on the north coast. This airfield posed a threat to Australia and communication lines to the United States. In August 1942, the United States conducted its first amphibious landing of the war to secure the area. Allied forces named the airfield Henderson Field. The campaign lasted six months and involved heavy ground, air, and naval combat.

The naval battles surrounding the island were exceptionally violent. Japanese forces used fast destroyers, known as the Tokyo Express, to resupply their troops at night. During the day, the Cactus Air Force defended the airfield. Many ships were lost in the waters near the Solomon Islands. This area of the ocean became known as Ironbottom Sound. In November 1942, a major naval battle occurred where Allied forces sank the Japanese battleship Kirishima. This was one of only two times in the Pacific theater that two battleships fought each other.

Following the war, the island underwent significant political changes. Honiara, located on the north coast, became the capital of the British Solomon Islands Protectorate. It later became the capital of the independent nation of Solomon Islands.

The former Henderson Field was converted into the Solomon Islands international airport. The secondary airfield, called "Fighter Two," is now a local golf course. Visitors can still explore military history at the Vilu War Museum.

The museum contains an outdoor collection of military equipment and aircraft.

Several memorials also stand to honor the soldiers who died during the conflict.

The island also hosts a unique variety of wildlife. The most notable mammal is the grey cuscus, also called the phalanger. This animal is a native marsupial. Other mammals include various species of bats and rodents. The forests are home to many colorful parrots. Estuarine crocodiles inhabit the shores, particularly along the Weather Coast in the south.

While venomous snakes are rare, a specific type of centipede has a very painful bite. In recent history, the island also faced internal tensions. In 1999, violence erupted between local Guale people and migrants from Malaita. This led to the intervention of the Pacific Forum in 2003 through Operation Helpem Fren.
