タロキナ岬
In early November, US forces had landed around Cape Torokina and established a beachhead, as part of Allied efforts to advance towards the main Japanese base around Rabaul, the isolation and reduction of which was a key objective of Operation Cartwheel. Facing the American beachhead at Cape Torokina were troops of the Japanese 17th Army, commanded by General Harukichi Hyakutake, the main elements of which were drawn from Lieutenant General Masatane Kanda's 6th Division. In response, the Japanese attempted a counter landing at Koromokina Lagoon, and began moving reinforcements north from southern Bougainville.
