 Thus began the Guadalcanal and Solomon Islands campaigns that resulted in a series of attritional, combined-arms battles between Allied and Japanese forces over the next year which, in tandem with the New Guinea campaign, eventually neutralized Japanese defenses in the South Pacific, inflicted irreparable losses on the Japanese military—especially its navy—and contributed significantly to the Allies' eventual victory over Japan.The delay in the advance of Japanese forces also allowed the Marine Corps to land on Funafuti on 2 October 1942, with a Naval Construction Battalion (Seabees) building airfields on three of the atolls of Tuvalu from which USAAF B-24 Liberator bombers of the Seventh Air Force operated.The atolls of Tuvalu acted as a staging post during the preparation for the Battle of Tarawa and the Battle of Makin that commenced on 20 November 1943, which was the implementation of Operation Galvanic.
