Location
Cause → Event → Consequence
As part of the broader New Georgia campaign launched in mid-1943, US forces sought to seize key harbor positions on New Georgia island. Viru Harbor was targeted early in the campaign to secure a potential base for PT boats and to dislodge Japanese defenders holding the area.
Elements of a Marine Raider battalion, accompanied by a US Army infantry company, conducted an overland advance from 28 June to 1 July 1943. Supported by airstrikes, the Marines executed an enveloping attack against Japanese forces around Viru Harbor, compelling the defenders to withdraw from their positions.
US forces took control of Viru Harbor and used it to support subsequent operations in the New Georgia campaign. However, plans to establish a PT boat base at the site were later canceled after the harbor was assessed and found unsuitable for that purpose.
