Joseon Naval Campaigns of 1592 - Aftermath

Aftermath

After attacking Busan, Yi retired to his Hansan Island base. For the rest of year, he remained relatively inactive, letting the progress of Ming Chinese assistance on the land take its effect. He still controlled all of the naval routes leading to the northern lines, which forced the Japanese to take the less dependable and more hazardous routes on the eastern coast. This proved ineffective in stopping the Chinese and Korean advances, and eventually Hanseong was recaptured, while the Japanese retreated to their bases around Busan.

Of course, the most obvious result was the devastating consequences of the Hansan Island Battle on the Japanese navy. 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.

Principally because of this, Yi won every single naval engagement in his entire naval career. And after his temporary imprisonment due to a false charge against him, Yi returned with a small fleet of 13 ships and shattered an entire fleet of Japanese ships at Battle of Myeongnyang in 1597. Afterwards, Yi led his campaign to the final Battle of Noryang in 1598, where he was killed in the battle.
