The landings were a military amphibious assault on Rendova Island in the Solomon Islands on 30 June 1943 by United States Army and Navy forces during the New Georgia Campaign of the Pacific War. In the assault, U.S. forces overwhelmed a small Japanese military garrison and secured the island. The U.S. occupied the island to use it as a staging and artillery base to support an offensive against Japanese forces guarding an airfield at Munda Point on nearby New Georgia.
