タロキナ岬
The Bougainville Campaign began on 1 November 1943 when the United States I Marine Amphibious Corps landed at Cape Torokina, around Empress Augusta Bay on the west coast of the Japanese-held island. The Allied invasion aimed to establish a defensive perimeter around Cape Torokina within which airfields would be built to attack the major Japanese base at Rabaul and support other operations in the region. The Allies did not intend to conquer the entire island, and the invasion area was mainly selected on the grounds that it was lightly defended and distant from the main Japanese bases at the northern and southern ends of Bougainville.
