At first the plan seemed to work well when Todo Takatora defeated Admiral Won Gyun at the Battle of Chilchonryang, but the plan was abandoned when the Korean navy under Admiral Yi Sun-sin defeated the Japanese fleet under Todo Takatora in the Battle of Myeongnyang with only 13 ships.
Mulanya rencana itu kelihatannya berjalan lancar ketika Todo Takatora mengalahkan Laksamana Won Gyun di Perang Chilchonryang, namun rencana itu diabaikan ketika angkatan laut Korea di bawah Laksamana Yi Sun-sin berhasil mengalahkan armada Jepang di bawah pimpinan Todo Takatora di dalam Perang Myeongnyang dengan hanya 13 kapal.
