Solomon Islands Campaign

Solomon Islands Campaign US marines invaded Guadalcanal to keep the Japanese from basing aircraft there in August 1942; they secured the island, and the nearby Russell Islands by February 1943. On 20 June 1943, USMC and army forces began attacking Japanese bases on and near New Georgia Island, and these were taken by 25 August. On 26–7 October, New Zealanders seized the Treasury Islands. On 1 November USMC and army units established a beachhead on Bougainville Island (which the Japanese resisted until March 1944), while Allied aircraft destroyed its Japanese airfields. By March 1944, US capture of the Admiralty and St Matthias Islands isolated Japanese garrisons in the Solomons by cutting their supply lines to Rabaul, against which the Allies next advanced in the New Britain campaign.
