The 1st Parachute Battalion was attached to the 1st Marine Division for the invasion of Guadalcanal. On 7 August 1942 the unit conducted an amphibious assault on the small island of Gavutu and later seized the neighbouring island of Tanambogo with other Marine units. The battalion later moved to Guadalcanal fighting alongside the 1st Marine Raiders in the Tasimboko raid and the Battle of Edson's Ridge. The high casualties suffered by the Marine paratroopers led the battalion to be moved to Camp Kiser in Tontouta, New Caledonia in September. The 2nd Parachute Battalion performed a diversionary raid on Choiseul Island in October 1943 and later joined the 1st and 3rd Parachute Battalion on Bougainville.
