Battle of Tulagi and Gavutu–Tanambogo

The Battle of Tulagi and Gavutu–Tanambogo was a land battle of the Pacific campaign of World War II, between the forces of the Imperial Japanese Navy and Allied (mainly United States Marine Corps) ground forces. It took place 7–9 August 1942 on the Solomon Islands, during the initial Allied landings in the Guadalcanal campaign.

U.S. Marines of the 1st Marine Division, commanded by U.S. Major General Alexander Vandegrift, and the invasion force under Brigadier General William Rupertus, captured the islands of Tulagi, Gavutu, and Tanambogo. The Japanese Navy had built a naval and seaplane base on these islands. The landings were fiercely resisted by the Japanese Navy troops who, heavily outnumbered and outgunned by the Allied forces, fought and died almost to the last man.

While the landings on Tulagi and Gavutu–Tanambogo were taking place, Allied troops were also landing on nearby Guadalcanal, with the objective of capturing an airfield under construction by Japanese forces. In contrast to the intense fighting on Tulagi and Gavutu, the landings on Guadalcanal were essentially unopposed. The landings on both Tulagi and Guadalcanal initiated the six-month-long Guadalcanal campaign and a series of combined-arms battles between Allied and Japanese forces in the Solomon Islands area.
