三川軍一
Marshal Admiral Isoroku Yamamoto promised the emperor that he would pay back the Allies for the disaster at the Bismarck Sea with a series of massive air strikes. For this, he ordered the air arm of Vice Admiral Jisaburo Ozawa's Third Fleet carriers to reinforce the Eleventh Air Fleet at Rabaul. To demonstrate the seriousness of the effort to the Supreme War Council, multiple shifts of high-ranking personnel were also effected: Both Yamamoto and Ozawa moved their headquarters to Rabaul; and Eighth Fleet commander Vice Admiral Gunichi Mikawa as well as General Imamura's chief of staff were sent to Tokyo with advice and explanations for the respective General Staffs (Admiral Tomoshige Samejima replaced Mikawa as Eight Fleet commander).
