Both plans started in July, but by mid-September, the Battle for Guadalcanal took priority for the Japanese, and troops in New Guinea were ordered to withdraw from the Port Moresby area to the northern part of the island, where they faced Australian and United States troops in the Battle of Buna-Gona.
Kedua rencana ini dimulai bulan Juli, namun pada pertengahan September, Pertempuran Guadalcanal dimenangkan Jepang, dan tentara-tentara di Nugini diperintahkan mundur dari Port Moresby ke bagian utara pulau, tempat mereka menghadapi tentara Australia dan Amerika Serikat dalam Pertempuran Buna-Gona.
