カートホイール作戦
The Allies re-cast their plans in early 1943. Following a major conference, on 28 March the Joint Chiefs of Staff issued a new plan for reducing Rabaul, which was designated Operation Cartwheel. Under this plan, MacArthur's forces were to establish airfields on two islands off the coast of New Guinea, capture the Huon Peninsula region of the mainland and land in western New Britain. The South Pacific Area was to continue its advance through the Solomon Islands towards Rabaul, culminating with a landing on Bougainville Island. While the initial plans for Operation Cartwheel directed MacArthur to capture Rabaul, in June 1943 the Joint Chiefs of Staff decided that this was unnecessary as the Japanese base there could be neutralized by blockade and aerial bombardment. MacArthur initially opposed this change in plans, but it was endorsed by the British and United States Combined Chiefs of Staff during the Quebec Conference in August.
