The Battle of Wickham Anchorage took place during the New Georgia campaign in the Solomon Islands during the Pacific War from 30 June – 3 July 1943. During the operation US Marines and US Army troops landed by ship around Oleana Bay on Vangunu Island and advanced overland towards the anchorage where they attacked a garrison of Imperial Japanese Navy and Army troops. The purpose of the attack by the U.S. was to secure the lines of communication and supply between Allied forces involved in the New Georgia campaign and Allied bases in the southern Solomons. The U.S. forces were successful in driving the Japanese garrison from the area and securing the anchorage, which would later be used to stage landing craft for subsequent operations.
