Top of the Ladder: Marine Operations in the Northern Solomons

The objectives assigned on Bougainville were to seize a substantial beachhead and build airstrips. Then American planes could assure final neutralization of the Japanese airfields at Kahili, Buka, and Bonis airfields at the north and south ends of Bougainville. Facing the invading Marines was a formidable enemy force dispersed on the island. At Buin, for instance, there were 21,800 Japanese. Responsible for the defense was an old adversary, Lieutenant General Haruyoshi Hyakutake, commander of the Seventeenth Army, and the man the Marines had defeated at Guadalcanal. His main force was the 6th Division. - Summary by John C. Chapin (2 hr 2 min)
