These campaigns made Yi a legendary figure in Korean history on par with, if not surpassing, the great general Eulji Mundeok.
The campaigns of Yi were vital in halting the Japanese invasion, which had the ultimate aim of conquering not just Korea, but Ming China as well.
Prior to the Okpo Campaign, Yi mainly patrolled the seas near his Jeolla Province, to fortify its position before he began moving westward, due to the call for help from Admiral Won Gyun.
Around the end of May, Admiral Yi set out again eastward and encountered another force around the Sacheon-Dangpo area, where he again engaged in minor skirmishes against the Japanese fleet.
For the rest of the year, he remained relatively inactive, letting the progress of Ming Chinese assistance on the land take its effect.
This proved ineffective in stopping the Chinese and Korean advances, and eventually Hanseong was recaptured, while the Japanese retreated to their bases around Busan.
In every future engagement, the Japanese commanders were afraid for their safety, considering Yi's manipulative use of the sea terrain, battle tactics, and frightening weapons as well as his innovative Geobukson.
