Battle of Rennell Island

The Battle of Rennell Island (Japanese: レンネル島沖海戦) took place on January 29–January 30, 1943, and was the last major naval engagement between the United States Navy and the Imperial Japanese Navy during the lengthy Guadalcanal campaign in the Solomon Islands campaign during World War II. The battle took place in the South Pacific between Rennell Island and Guadalcanal in the southern Solomon Islands.

In the battle, Japanese naval land-based torpedo bombers, seeking to provide protection for the impending evacuation of Japanese forces from Guadalcanal, made several attacks over two days on United States' warships operating as a task force south of Guadalcanal. In addition to approaching Guadalcanal with the objective of engaging any Japanese ships that might come into range, the U.S. task force was protecting an Allied transport ship convoy that was carrying replacement troops to Guadalcanal. As a result of the Japanese air attacks on the task force, one U.S. heavy cruiser was sunk, a destroyer was heavily damaged, and the rest of the U.S. task force was forced to retreat from the southern Solomons area. Partly because of their success in turning back the U.S. task force in this battle, the Japanese were successful in evacuating their remaining troops from Guadalcanal by February 7, 1943, leaving Guadalcanal in Allied hands and ending the battle for the island.
