Yi Sun-sin

Life overview

Yi Sun-sin was a naval commander of Joseon during Japan’s invasions of 1592–1598. These stages connect his capital origins, the Yeosu command and three battle regions. The map shows selected places in his life, not reconstructed fleet movements or modern national borders in the sixteenth century.

   Born in the capital

   Hanseong, now Seoul City-level representative point

   Yi Sun-sin was born in Geoncheon-dong in Joseon’s capital, Hanseong. The city is now Seoul; the pin does not identify a surviving birthplace building. His later naval career unfolded far to the south, so this first stage establishes his origins before the coastal commands and battle regions that follow.

   1591

   Preparing a naval command at Yeosu

   Yeosu City-level representative point

   After passing the military examination in 1576 and serving in several posts, Yi became Left Naval Commander of Jeolla. His headquarters were at Yeosu, where he prepared ships and trained forces before the invasion. The city point represents this command base; the present Jinnamgwan hall was first built by a successor in 1599.

   1592, seventh lunar month, day 8

   A combined fleet at Hansan

   Waters near Hansan Island Representative area

   During Japan’s invasion, Yi and other Joseon commanders fought a Japanese fleet near Hansan Island. They drew opponents out from narrower waters and deployed a spreading formation in the wider sea. The victory belongs to a combined naval operation, not a lone individual; the pin marks a battle region rather than a precisely reconstructed manoeuvre.

   1597, ninth lunar month, day 16

   Rebuilding command at Myeongnyang

   Myeongnyang Strait, near Jindo Representative area

   After dismissal and a later return to naval command, Yi led a reduced force at Myeongnyang, the narrow strait between Jindo and Haenam. The fleet resisted a larger Japanese force, preserving a basis for further naval operations. This location highlights the strait’s geography; it does not trace every ship’s movement or claim an exact casualty count.

   1598, eleventh lunar month, day 19

   The final battle at Noryang

   Noryang Strait Representative area

   Yi’s Joseon fleet and Ming forces under Chen Lin fought Japanese ships near Noryang as the war was ending. Yi was killed during the battle. His diary had recorded the preceding years’ combat, weather and daily hardships; later accounts preserve additional memories. The regional point does not identify the vessel or exact place of his death.

Legacy and context

His campaigns depended on crews, ships, preparation and other commanders, including Ming allies in the final battle. His surviving diary records war alongside weather, loss and everyday concerns. Later turtle-ship illustrations are useful historical objects, but cannot simply be treated as exact pictures of his own vessels.
